The best power bank for most is the Anker PowerCore 5000 . It is cheap and handy and you can charge the smartphone once or twice full. If you’re traveling longer without a power outlet and need more capacity, you should take a look at the Revolt Powerpack . For very long tours, the RAV Power RP-PB006 delivers huge power reserves.
UPDATE January 28, 2019
We have heavily overhauled the article and removed some models that are no longer available.
After our last tests of 18 and 28 Powerbanks, we have this time nine more current reserve batteries under the microscope. All in all, we have now tested more than 50 Powerbanks for you.
We have divided the batteries into three groups according to their capacity: small power banks with up to 10,000 mAh (milliamp hours), medium to 20,000 mAh and large over 20,000 mAh. For each of the three sizes we have chosen a test winner and found alternative recommendations for you.
Why do you need a power bank?
Powerbanks are the best way to solve one of the biggest problems of the mobile age: the limited battery capacity of smartphones and tablets. In handy format they are very useful for the everyday train ride to work or as a huge energy storage for the long weekend in nature. External power banks are thus the mobile emergency power socket for refueling the flimsy battery.
Spare batteries solve the problem of small smartphone batteries
Depending on the capacity of the battery pack and the size of the cell phone battery, the emergency power for one or more charges sufficient. Numerous manufacturers offer powerbanks in many different sizes: from a modest 3,000 to a proud 30,000 milliamps (mAh) and more. Naturally, with the capacity, the dimensions and weight of the devices increase – and, as a rule, the price.
The market for power banks has grown enormously. We have looked at a total of 55 copies of various categories for you, tested and each one recommendation. We have divided the additional batteries into three categories: up to 10,000 mAh, up to 20,000 mAh and from 20,000 mAh.
Since you can not really rely on the manufacturer’s information on capacity, we measured all the power banks. We wanted to know how many milliwatt hours (mWh) of energy actually flow when a battery pack is completely discharged and then compared the measured values with the manufacturer’s specifications.
We charged each power bank and then discharged it on a tablet until it stopped supplying power. The measurements were made using a USB multimeter. Because of the better comparability we have always carried out the test with the same cable.
Many manufacturers give too high capacity values
Since the voltage has a major impact on the maximum amount of energy that can be removed, we tried not to drop the charge level of the test tablet below 30 percent during the measurement and not allow it to rise above 70 percent. Because in such a range, the charging electronics usually does not regulate the flow of current, so that all power banks were discharged with the same voltage.
As in almost every modern device with a battery, even in power banks an electronic system prevents the battery from being completely discharged. A certain residual amount of energy is always stored, otherwise the battery will be damaged. However, this is irrelevant in practice, as the mentioned remainder is not available to the smartphone or tablet and therefore uninteresting for the user.
In addition, the transformation of the voltage provides for a loss of energy. The 3.7V of the powerbank battery needs to be converted to 5V for the USB output. This is the standard voltage for USB ports, only with it can be a smartphone or tablet charge.
The unused residual energy in the battery and losses in the voltage conversion again ensure a difference between the manufacturer’s information and the actual usable capacity of a power bank.
In addition to the measurement of the actual amount of energy that give the battery pack, also interested in the charging time. For this we charged each model with a 2 ampere charger and measured the charging time. Except for a test device, all power banks use a USB input with at least 2 amps, some even with 3 amps. Models with an input that accepts a higher current benefit from a high-performance power supply.
Usually you use the USB charger from the smartphone – or just the USB port of a laptop or PC. Therefore, our test series rather serves the comparability of power banks with each other. How it looks in practice at home users, always depends heavily on the used power supply. Because many smartphone chargers deliver only 1 amp and many PC USB sockets do not produce 3 amps. You can read about the current intensity of a charger on the device – usually in very small print.
The little basics of battery physics
Determining the capacity of a battery is not that easy in practice. For example, it depends on the ambient temperature – in the cold, a battery delivers significantly less power than at room temperature. We all know the problem that batteries lose their capacity over time. And even when charging and discharging itself is lost power, incidentally, the quality of the USB cable plays a major role. The amount of energy that gets into a battery is never the same, which comes out again.
Many manufacturers take advantage of such uncertainties and sometimes exaggerate their data on the capacity of their battery packs – according to the motto: No one can exactly check it anyway. Especially with no-name manufacturers from the Far East, you can not be sure that everything is in it.
The watt-hour is more meaningful than the milli-hour, which specify the manufacturer
It has become customary to specify the capacity of batteries in milliamp hours. This is actually a unit that says little about the actual capacity of a battery.
Significantly more meaningful than the milliamperehour (mAh) is the unit (milli Watt-hour) (mWh or Wh), which stands for the electrical work and thus for the amount of energy that can give a battery. In addition to the amperage, the voltage in volts that is used to discharge the power bank battery also flows here. The voltage affects the usable capacity or the amount of energy that a smartphone can actually pull out of a battery pack.
Small calculation example: An additional battery with 10,000 mAh performs at 3.7 volts exactly the same electrical work as a battery with 1000 mAh at 37 volts – namely 37 Wh. The indication of the milliamp hours alone says so little, the decisive watt hour. However, 10,000 mAh sound no doubt more impressive than 37 Wh, which is why the manufacturers probably prefer their indication. After all, the providers of almost all of us battery packs tested now indicate the capacity both in milliamp hours (mAh) and in watt-hours (Wh) or milliwatt hours (mWh).
How long does the battery pack last?
Most smartphone batteries have a capacity between 2,500 and 3,500 mAh. However, they generally deliver 3.8 volts, which is why the milliampereck of the battery pack can not be compared directly with that of the smartphone. If you want to know how often you can charge your smartphone with a battery pack, so you should rather look at the watt hours.
At 3,000 mAh and 3.8 volts, it comes to around 11,000 mWh capacity for an average smartphone. If a battery pack has a capacity of 20,000 mWh, it can be fully charged just under two times.

The best little power banks
Small power banks are popular because they are slim and compact and you can always have them with you. And to recharge the phone once or twice, their capacity is always enough.
By small power banks we mean devices from 5,000 to 10,000 mAh. Below 5,000 mAh are not recommended in our view.
Short overview: Our recommendations
Anker PowerCore 5000
The Anker PowerCore 5000 is so small that it simply disappears into the hand or jacket pocket. In our test, the device could almost confirm the manufacturer’s information on capacity – a rarity, because here is a lot of cheating. Also, the charging of the power bank is fast, so it is the best small power bank for us.
Poweradd Slim 2
If you only look at the price, buy the Poweradd Slim 2 . The model is the cheapest in the entire test, but also provides only three quarters of the capacity, which promises the manufacturer. But that is enough to provide the smartphone with energy for a few hours, when the charger is at home or the next outlet is out of reach.
Test winner: Anker PowerCore 5000
For most smartphone users who want to recharge their batteries on the go, but do not feel like carrying large backup batteries, Anker’s PowerCore 5000 model is currently the best choice.
As the name suggests, the manufacturer indicates a capacity of 5,000 mAh or 18,500 mWh. In the field test 17,222 mWh were available. That’s a whopping 93 percent of what the manufacturer promises – an absolute top value. About one and a half times can be used to charge a cell phone battery.
Power banks up to 10,000 mAh are usually sufficient
As is usual for small power banks in the category up to 10,000 mAh, the Anker PowerCore 5000 only has one USB output. It charges 2 amp devices connected, which is industry standard. Also more and more smartphones support higher charging currents, so that the battery of the device is charged much faster.
The micro USB port for charging the battery pack also supports currents up to 2 amps. If you use a charger that provides the corresponding values, you benefit: the power bank is faster and fully operational again. In our test with a corresponding charger, the battery of the PowerCore 5000 was charged after 2:36 hours. This equates to a charging time of 9 minutes per watt-hour (Wh), making Anker one of the fastest in the test field.
With its small size of about 10 x 3 centimeters and a weight of 144 grams, the PowerCore 5000 is ideal for on the go. It fits comfortably in every pocket and does not stand up any further. Also the round plastic case is – as one knows it from Anker – solid processed and should join almost every tour – as long as it stays dry. How much energy is currently in her, the power bank reveals about 3 small LEDs.
With a price of 75 cents per watt-hour, the model is priced at the average of the power banks, but it delivers an above-average performance. The Anker PowerCore 5000 is a power bank that most people want: stable, handy, cheap – and the manufacturer remains realistic in terms of capacity.
If you can not make friends with Anker PowerCore, here are some recommendations for you.
Poweradd Slim 2
If you are looking for a cheap power bank to keep the smartphone battery afloat in the worst case, you can use the Poweradd Slim 2 . With less than 10 euros, it is the cheapest in the entire test field and thus our tip for saving foxes.
However, in our measurements, it only delivered 75 percent of the manufacturer’s stated capacity: 13,917 out of 18,500 mWh. And once fully charged takes 3:12 hours – not very fast. These are the disadvantages that you would probably have to accept for such a low price.
On the other hand, it scores again with a compact (10 x 3 cm) and extremely light (140 grams) design, so that it does not stand out in the handbag, backpack or even in the jacket pocket. In terms of connectivity, it offers the standards: a microUSB port for up and a normal UBS output for unloading.
We’ve also tested the following power banks
The best mid-sized power banks
In the category up to 20,000 mAh there is a lot of choice. Such power banks offer enough capacity to survive even a weekend without a socket and are still comparatively light and handy.
Short overview: Our recommendations
The Revolt Powerpack is for us the best power bank in its category. It is compact and lightweight and still offers plenty of energy, the manufacturer promises not too much here. It also has two USB outputs, so you can charge two smartphones in parallel – a real all-rounder.
The EasyAcc PB16750MS is also worth a recommendation, not only because of the large energy storage with nominal 16,750 mWh. It has two USB inputs (including even a USB-C port) and two USB outputs, so that even here two smartphones can be charged in parallel. One of the outputs even powers 12 volt devices.
A completely normal power bank without bells and whistles is the CoolReall K6 . It offers a very good price-performance ratio and can score with a usable capacity yield of 85 percent. The rest is standard – which is not meant to be negative. She just does what she should and for a reasonable price.
equinux tizi powerhouse Powerstart
A special alternative is the tizi powerhouse Powerstart by equinux. He can spend 200 amps for two seconds and get a car up and running again. That one should not use the function constantly, because the power bank does not do well in the long run, is clear. In addition, she is one of the hardest in the test field and therefore not suitable to be carried in the purse. Your place is best in the glove box, because it can, if necessary, to serve you well.
Test winner: Revolt Powerpack
Whoever wants to spend the weekend without a socket but not without an empty smartphone battery, accesses a power bank with higher capacity. In the category up to 20,000 mAh, the Revolt Powerpack with 10,000 mAh is our recommendation.
Of the 36,000 mWh that the manufacturer promises, the test left 33,350 mWh. This corresponds to 93 percent and also a first-class result, because only few power banks reach values beyond the 90-Prozent-Marke. A smartphone can be fully charged up to three times.
A weekend without a socket is no problem with the EasyAcc
Why we also recommend the model: The built-in batteries require little space and are quite light. The Powerpack brings a weight of 195 grams on the scales, which corresponds to 6 grams per measured watt-hour, a low, which reach only a few other models. Thus, the power bank fits easily into a purse and backpack and still provides enough energy when the mobile phone battery runs dry and needs to be charged urgently.
Speaking of charging: The Revolt Powerpack has two USB outputs, so you can charge two smartphones, tablets or other devices. The third port, a USB micro input, charges the power bank. For this she needs 5 hours in the test, others get it a little faster. Nevertheless, the revolt is our recommendation for those who are looking for a cheap and compact power bank with a lot of capacity.
The EasyAcc PB16750MS is our former test winner in the category and of course still a recommendation. 60.800 mWh promises the manufacturer, we measured in the test 55,331 mWh. This is quite impressive, after all we are talking about 91 percent. The smartphone can be fully charged with the power bank up to five times.
What makes the model so special, are the connections: In addition to the micro-USB input with 2 amps, there is still a USB-C input with 3 amps. In addition, the power bank can load faster, if you have a cable with USB-C plug and a 3-amp charger. Positive: The delivery includes two cables with two plugs.
More and more smartphone manufacturers are using USB-C instead of micro-USB, so that the new type of USB will probably spread in the coming years. With the PB16750MS you are already fit for the future. By the way: Both inputs can also be used in parallel to recharge the power bank – then it’s even faster.
The EasyAcc also offers two outputs, but it is twice a normal USB-A port. However, one of the two supplies a voltage of up to 12 volts (at a maximum of 1.25 amps). This corresponds to the voltage of a cigarette lighter, which can be used to operate corresponding car accessories such as mini-fans or FM transmitters.
When a smartphone is plugged in, the voltage drops to 5 volts and 3 amps of current flow – more than most other power banks that deliver a maximum of 2 amps. The advantage: the smartphone is charged faster.
With 65 cents per watt-hour, the PB16750MS belongs to the average price-performance ratio. At 6 grams per watt-hour (328 g in total) it is comparatively light, but with its 14 x 8 x 2 centimeters it is definitely not yours anymore. On the other hand she is fast when charging. In the test on our 2-amp charger, it only took 7:20 hours, equivalent to 7 minutes per watt-hour.
Like many other power banks, the EasyAcc has a built-in LED flashlight. Big difference here: It is actually useful because they are relatively bright – in an emergency a practical thing, but not a substitute for a real flashlight.
If you are looking for a cheap power bank with a lot of capacity and no other bells and whistles, then the CoolReall K6 is in good hands. The model has the best price-performance ratio in the entire test field: 1 watt-hour costs just 33 cents.
In the capacity test, the power bank came to a rate of 85 percent: 57,700 mWh promises the manufacturer, 48,945 mWh were really out – useful.
As far as the other features are concerned, the CoolReall is limited to standards: the device is charged via a 2-amp micro USB socket, discharged via two USB-A outputs, which deliver a maximum of 2.1 amps. If you want to charge two smartphones in parallel, you have to be patient.
This also applies to the refill of the power bank itself: In our test on the 2-amp charger, it took 8:35 hours, equivalent to 10 minutes per watt-hour – not particularly fast, but to cope.
An LED light is also installed, but it is really not good as a flashlight.
equinux tizi powerhouse Powerstart
A very special power bank is the tizi powerhouse Powerstart of the German manufacturer equinux. With it you can recharge an empty car battery or start the car by a short surge.
For the latter, it provides 200 amperes for 2 seconds – however, the manufacturer warns against extreme wear. On the other hand, you will not start your car all the time. But if you stay lying down, the powerhouse Powerstart can be the salvation. A special car charger cable with terminals is even included, the connections hide behind a small flap.
Two normal USB outputs with 1 and 2.4 amps are also on board. Another special feature is the built-in light, which comes very close to a real flashlight.
In the test, the model delivered 35,946 mWh from a promised 44,400 mWh, which corresponds to an average of 81 percent. You can charge your smartphone around three times.
With 2.23 euros per watt-hour, however, it is quite expensive and with 550 grams one of the heaviest power banks in the test field. It is very robustly built for that. Thus, the tizi Kraftprotz Powerstart makes itself especially good in the glove compartment and donates power and light to drivers in an emergency.
We’ve also tested the following powerbanks
Anker PowerCore II 10000
The Anker PowerCore II 10000 has the peculiarity that it provides up to 12 volts of voltage (then at a lower current of 1.5 A) and thus also drives 12 volt devices. Incidentally, this corresponds to the voltage of a car battery. She is in 4:33 hours she is fully charged – that’s pretty fast. The weight is pleasingly low at 191 grams. The capacity is with at least 86 percent of the manufacturer’s information in the frame. Unfortunately, the power bank is not the cheapest.
Intenso ST 13000
At around 9 minutes per watt-hour, the Intenso ST13000 is not necessarily fast in charging for a total of 6:28 hours. Its capacity yield is decent at 87 percent, and at a weight of 6 grams per watt-hour, it is in the truest sense of the word portable. The connection field is also ok, but you will not find anything special in vain. Unfortunately, the ST13000 is relatively clunky and, like its price, could be a bit narrower.
Anker PowerCore 10000
The Anker PowerCore 10000 is also relatively fast with 8 minutes per watt-hour, because after 4:44 hours it is fully charged. In addition, she is quite light at 194 grams. The capacity is a staggering 89 percent of the specified value. However, the connector panel with just one input and one output is quite meager. For the high price you get much better power banks – the sister model from the house, the PowerCore II, including.
The Aukey PB T3 , as already the anchor Powercore II, also operate with a voltage of 12 volts. After all, their measured capacity corresponds to 84 percent of the manufacturer’s information, which makes them not one of the top candidates in terms of energy yield, but does not have to hide. Unfortunately, the power bank weighs too much and its price is clearly too high for what it delivers.
Varta PB 16000
The Varta PB 16.0000 has a capacity of 86 percent and loads with 7 minutes per watt hour also quite fast. It’s not very expensive, but it does not have any great highlights to set it apart from the others – so average. Unfortunately, with almost half a kilogram she is extremely heavy. And also measured by the watt hours she just weighs too much.
The best big power banks for 2019
If you want more, there are more than 20,000 mAh power banks. So you can keep your cell phone running for days off the beaten track – or even charge a laptop.
Short overview: Our recommendations
RAV Power RP-PB006
Our test winner in the big category is the RAV Power RP-PB006 . The measured capacity of 68,650 mWh almost matches the manufacturer’s specifications – no other power bank was better in the test. This allows most smartphones to charge about six to seven times. That’s huge and even enough for a short break.
Just a big energy store for little money? Then you get the right powerbank with the CoolReall K8 . It offers a very good price-performance ratio and can score with a usable capacity rate of 86 percent.
The Powerbank recommendation for outdoor friends is the EasyAcc Outdoor . The case is very shockproof and waterproof – at least if you have closed the flap behind which the connections are installed. A flashlight is conveniently installed and that is also quite useful. Rather average, but still in order, the yield of 83 percent and the price.
Another, but very special alternative is the Anker PowerCore+ , which has a special feature: It supports the “USB Power Delivery” specification (USB PD). The power bank delivers a power of up to 30 watts via a USB-C connection. This can be used, for example, to charge notebooks. If the power bank is to be recharged, however, this only works via the USB-C port. So you do not have to wait several days, you need a special power supply with high performance, which is not supplied by the manufacturer, however.
Test winner: RAV Power RP-PB006
The extended weekend on the campground or in the mountains is no problem with a large power bank beyond the 20,000 mAh. This provides not only a mobile phone with power, but if needed, a tablet or the devices of fellow travelers.
RAV Power RP-PB006
The RAV Power RP-PB006 sets in our opinion the most important discipline the best: The measured by us actual capacity of the power bank reaches 95 percent of the manufacturer ‘s specification . This has not yet done a model tested. Of the promised 72,000 mWh, the user gets 68,650 mWh in practice – not bad!
Thus, the power bank also offers a good price-performance ratio, because we calculate based on the measured capacity. Sure, there are other power banks in the 20,000 mAh class that are cheaper at first glance. But there is often much less power from the USB port than promised. The RP-PB006 costs a good 41 cents per Wh.
In other disciplines, our test winner has no special features such as USB-C, permanently integrated cable or a flashlight to offer. Also, the current and voltage that support the USB inputs and outputs are standard. This will not bother anyone who only wants to charge smartphones and other compact devices. With the RAV Power RP-PB006 you simply get a power bank with large capacity.
If you are looking for a cheap power bank with a lot of capacity and no other gadgets, then the CoolReall K8 is in good hands. The model has the best price-performance ratio in the entire test field: 1 watt-hour costs just 31 cents.
In the capacity test, the power bank came to a decent rate of 86 percent: The measured 48,945 mWh are enough for four to five loads.
The CoolReall K8 is a simple powerbank for a low price and with a lot of capacity. It has a micro USB socket for charging with a maximum of 2 amps and three USB outputs. With a maximum of 4.8 amps it will charge your smartphone and more. These are standard values in the power bank industry, which is why it is not the fastest when refilling with just under 10 hours – but also not among the slowest in the test field counts.
An LED is also installed, but it is really not good as a flashlight.
Just on the move or on camping trips, if just no power outlet is available, power banks are used. If you like doing something more robust on the go, the EasyAcc Outdoor is just right for you. Their clou: The reserve battery is built particularly shockproof and water can not harm him. The housing is certified to IP67 and therefore dust and waterproof. A water depth of one meter should survive unscathed for half an hour.
The test in a bucket showed that the circuits are not damaged within 30 minutes, at least with a water column of 50 centimeters. Even heavy rain or a fall into the water, the power bank so easily – if you close the small flap, behind which all ports (a micro USB input and two USB-A outputs), closes properly. If you just load your smartphone and the power bank falls into the water, one of the otherwise waterproof housing does not help.
In keeping with the concept of an outdoor power bank EasyAcc has installed a flashlight, which is quite useful as such. It is relatively bright, which can not be claimed by many power bank lights. Three modes are offered: Continuous, flashing and SOS signal.
In our measurements, EasyAcc Outdoor achieved 61,223 mWh of a promised 74,000 mWh – that’s 83 percent. That’s just fine. It took her 11:03 hours or 10 minutes per watt hour to charge – not very fast, but okay. Also just okay: the price of 72 cents per Wh.
If you are looking for a robust, waterproof power bank, the EasyAcc is still worth a look. Otherwise you get with our other recommendations more for his money.
The Anker PowerCore + supports the specification »USB Power Delivery« (USB PD). This means that the power bank provides an electrical power of up to 30 watts via the USB-C port in order to be able to charge notebooks, for example. A few current notebook models, such as the new MacBook, namely use the USB socket for power supply. However, not all notebooks are compatible with USB PD. This is how Anker excludes the HP Specter and the Dell XPS 13.
The power bank has a capacity of 96,480 mWh according to the manufacturer. In the test, we measured 79,533 mWh, which corresponds to a rate of only 82 percent – just fine. For the special use as a USB-PD power bank but you may still accept that.
In addition, the PowerCore + has two normal USB-A outputs, each delivering up to 3 amps – that is 1 amp more than most of the power banks in the test.
The model can only be charged via the USB-C port mentioned above, which is used both as an output and as an input. The problem: When charging via a normal USB charger, the process takes several days. Instead, it must have a special power supply that delivers the right performance. Such a power supply is not included. Anchor only attaches a cable with USB-C plug at both ends.
At 591 grams, the Anker PowerCore + is the second-heaviest powerbank in the test field. It makes a very solid and high quality impression. The ten LEDs, which are arranged in a circle, indicate the charge level of the battery.
With a price of 79 cents per watt-hour, it is also not particularly cheap – but it has fallen significantly since the market launch. All in all, it is aimed at users who are actually looking for a power bank with USB PD. They are still rare in the trade so far. If you only want to load smartphone and tablet, you can use another model.
We’ve also tested the following power banks
The Aukey PB-N36 is the only power bank in the test that has a Lightning connector for Apple charging cables. It also addresses owners of iPhone and iPad, but a cable for a micro USB input is also included. The price per watt-hour on the 20,000 mAh model is also very cheap. As a treat, Aukey has also donated a flashlight to his power bank.
Anker PowerCore II 20000
The Anker PowerCore II 20000 with 20,000 mAh and charges fast with 7 minutes per watt-hour. The capacity is 84 percent of the manufacturer’s specification, which is just fine. Besides, the powerbank is nice and light. But this is again at the expense of the connections, because as so often at anchor, the device must be satisfied with only one input and two outputs. The price is not absurdly high, but in comparison to other models, it is not enough for a recommendation.
Anker PowerCore 20100
The Anker PowerCore 20100 actually has 86 percent of the stated 21,000 mAh capacity and is one of the rather lightweight candidates. In direct comparison to similar PowerCore II 20000, unfortunately, it loads a good deal slower and waives the optional voltage of 12 volts. Otherwise, she is similarly heavy and looks like her sister like an egg to another. Because it is hardly cheaper, we would therefore prefer the powerCore II – or even resort to a completely different device.
Anker PowerCore Speed 20000 PD
The most noticeable thing about the Anker PowerCore Speed 20000 PD is that it also has USB PD. However, in comparison to the PowerCore +, it offers less capacity at a similar price – we would rather recommend the same level of competition from the same house, even if it weighs a few grams more. The high-performance power supply is also necessary for the PowerCore Speed, so you do not have an advantage in spite of lower capacity. Also the connection field remains as usual.
The EasyAcc PB20000MS also has a capacity of 20,000 mAh with a fairly modest 84 percent measured yield. The connection panel is stately with two inputs and four outputs for USB. Unfortunately, the power bank is very lame when charging – a full 12 minutes, the battery needs per watt-hour, which comes to a duration of 13 hours for a full charge. After all, the PB20000MS is relatively cheap.
The EasyAcc PB26000MS has a capacity of 26,000 mAh, but otherwise differs only marginally from the smaller sister. It is almost the same weight, is equipped with the same connections and visually they are very similar. However, the capacity yield is 2 percent higher and above all, the device loads much faster than the PB20000MS. But the price in relation to capacity but much higher – too high, as we find.
