Frequently Asked Questions: 10000mAh Power Banks

What does “mAh” mean on a power bank?

As soon as you deal with the topic of power banks, you will be confronted with the abbreviation “mAh”. This is a unit of measure for electrical charge and stands for milliampere hours. It indicates the available charge or, more precisely, the charge carrier capacity of a rechargeable battery or batteries.

That means, mAh tell you how long (measured in hours) the power bank can deliver a certain current (measured in milliamps).

Specifically, this means the higher the capacity in mAh, the more often you can charge your smartphone with it, for example. If the power bank has several outputs, you can even charge two or more devices at the same time with a higher capacity.

For which devices can I use a Power bank with 10000mAh?

In principle, the power bank is an external battery that you can use to charge any device that has a USB port. However, it makes sense if the capacity of the power bank exceeds the consumption of the device to be charged.

Possible devices include, for example, your smartphone, tablet, notebook, mp3 player, game console, camera or e-book reader.

Do I need an adapter for certain devices or cable connections?

If you are the owner of an iPhone or a smartphone that already has a USB-C connection, it must be ensured that the power bank also has these suitable connections.

Since you probably don’t want to buy a separate power bank for each device in order to have the right connection, you can also buy different adapters. These are then simply plugged onto the existing cable.

How do I charge a Power bank?

Charging the power bank is as simple as using your smartphone. You need a USB cable for this and you have two options.

  • Charging the power bank via PC / notebook
  • Charging the power bank via a power supply unit at the socket

It is essential that you make sure that the type of USB connection on your power bank matches that of the power supply unit or your PC connections. Many devices are now equipped with a USB-C cable connection.

If you want to charge your power bank on your PC / notebook, you simply connect the smaller micro USB port to the power bank and the larger USB port directly to your PC / notebook.

If you want to charge the power bank at the socket, the cable is connected to the power supply via USB. You plug the smaller micro-USB connection back into the power bank and the power supply unit into the socket.

Usually only the USB cable and no power supply is included. You can either buy suitable power supplies separately or simply use the power supply of your smartphone or tablet. Here, too, it is important to check beforehand whether the connections match!

How long does it take for a power bank to be fully charged?

How quickly a power bank or even your smartphone is fully charged by the power bank depends on several factors:

  • Charging speed in amperes (A)
  • Capacity of the power bank in mAh
  • Power supply (cable, power supply unit and, if necessary, adapter)
  • Quick charge capability

Charging speed in amperes (A)

The charging speed of a device is measured in amperes. Each description of a device and a power bank must include this charging speed in the properties. For example, you will often find the specification Input 2A on a power bank with 10000mAh.

These 2A mean that the charging speed is two amps and is therefore twice as high as with a power bank with 1A charging speed.

Capacity of the power bank in mAh

As already mentioned above, the capacity indicates how long the power bank can deliver a certain amount of current. The higher the value in mAh, the more current the power bank can deliver to the device to be charged.

The more capacity, the longer it takes for the power bank to be fully charged. The same applies of course to the device to be charged.

This can easily be compared to a water tank. The bigger the tank, the more flowers can be watered with it. However, it also takes longer to refill a large water tank.

Power supply (cable, power supply unit and, if necessary, adapter)

The power supply is better guaranteed via the socket than via the PC or a notebook. This is due to the fact that more charging current can be made available via the socket, while the PC makes less available. In addition, the PC itself uses electricity during this process.

The power supply unit also plays a role, as different power supply units can provide different amounts of charging current. Larger capacity power banks require more amps than smaller capacity power banks.

Larger power banks can usually be charged with lower amperages without any problems, but on the one hand it is better for the battery if as much charging current can be provided as the power bank needs and on the other hand, the charging process is faster.

If you charge the power bank using an adapter, it may also be that less charging current is made available. Therefore, the charging process can take longer here than without an adapter.

Quick charge capability

Certain technologies charge your power bank significantly faster. This is made possible by the transmission method of electrical power via the USB interface developed by Qualcomm (Quick Charge) and Anker (Power IQ).

The actually limited power of chargers and USB connections is increased by means of a special power supply unit, so that more electrical voltage is transmitted to the USB cable and the device.

A protocol creates a connection between the charger and the end device and reads out the device-specific charging parameters. The built-in chip knows how much power the device has to output for charging and adapts to the requirements of the device. These technologies therefore stand for intelligent charging.

Similar methods are offered by Samsung as “Adaptive Fast Charging” or by Oppo Electronics as VOOC (Voltage Open Loop Multi-Step Constant-Current Charging).

How often can I charge a Power Bank?

The number of charges depends on the capacity of the batteries. On the one hand from the capacity of the power bank and on the other hand from the capacity of the device to be charged.

For example, if the battery of your smartphone has a capacity of 2000 mAh, you can theoretically fully charge the smartphone five times with a power bank of 10000 mAh. If you have a power bank with only 1000mAh, you can only charge your smartphone up to 50% once.

In practice it is unfortunately not that easy to calculate. You will find out why in the next section.

Does the stated capacity correspond to the actual capacity in practice?

The manufacturers indicate the capacity of devices and power banks. For example, with a power bank capacity of 10000mAh, you would have to be able to fully charge an iPhone X with 2700mAh (10000mAh / 2700mAh =) 3.7 times.

However, this is not entirely the case in practice. One speaks of gross capacity and net capacity.

Caution: The capacity specified by the manufacturer does not correspond to the capacity ultimately available in practice!

The actual capacity (net) depends on various factors:

  1. The power bank and the device to be charged (e.g. smartphone) have a different energy content (in watt hours Wh) due to different nominal voltages. If you compare these (Wh Powerbank / Wh device), there is already a small first difference.
  2. The device to be charged, for example, requires a voltage of 5 volts, but the power bank is only designed for 3.7 volts. To achieve the 5 volt output voltage, additional energy is consumed through heat (10-15%).
  3. Conversely, the device loses energy or heat (also here 10-15%), as the 5 volt input energy is converted back into a lower voltage level according to the charge level of the battery.
  4. Every battery has a self-protection. If you were (able to) discharge the power bank completely every time, the battery would be damaged. Therefore, the protective mechanism is such that the power bank switches itself off at some point before it damages the battery.

In summary, a good fifth of the energy is lost through points 2 and 3 alone.

In addition, there are losses due to the different energy contents (battery voltage x capacity) and the self-protection of the battery. This ensures that approx. 5-10% of the capacity cannot be used up.

Can I take my power bank with me on the plane?

There is a very high probability that you will never see power banks that are checked in with your luggage. Since these are noticeable in the security check when scanning the luggage, your suitcase is opened and the power bank is removed.

Your power bank may not be checked in with your luggage on any airline. If you want to take your power bank with you on an airplane, it has to be stowed in your hand luggage.

Furthermore, as a worst-case scenario, in such a case you have to get along without your suitcase on vacation. If it takes too long to check and remove your power bank, the plane may take off without your suitcase.

Why are there regulations for a power bank at all?

It is important to avoid any risk in the aircraft. Power banks are normally not dangerous, but the batteries in a power bank can cause a short circuit. If this reaction occurs, heat is generated. This in turn can set the battery itself, surrounding devices or objects on fire.

If something like this happens unnoticed and between thousands of pieces of luggage in the hold of an aircraft, it has serious consequences and is likely to lead to a disaster. You or the people sitting next to you should notice a fire in hand luggage very quickly and major damage can be prevented.

Unfortunately, there are no general rules for carrying in hand luggage that apply to all airlines. It is therefore extremely advisable to get information directly from the airline you are going to fly with beforehand.

What alternatives are there to a 10000mAh power bank?

In addition to a power bank, there are also a variety of other options for conveniently charging your devices on the go. You can find out which ones are here:

  • Solar chargers: The practical solar chargers are portable, environmentally friendly and independent power sources. Unlike a solar power bank, these devices do not have an integrated battery, so the energy cannot be stored. The advantage of a solar charger, however, is that it is often significantly larger than a solar power bank and can therefore generate more electricity. But do not worry, they are not huge, unwieldy devices, as the solar panels are usually installed as thin, fold-out parts.
  • SunnyBag: As the name suggests, SunnyBag is about bags and rucksacks that generate electricity with the help of the sun. This is made possible by flexible and waterproof solar panels that are integrated into the bags. The manufacturer, a start-up company, also offers the LEAF + system, with which any normal backpack and bag can be subsequently converted into a solar charger.
  • HandEnergy: HandEnergy is just as big as a tennis ball. According to the Irish inventors, this tool can be used to generate electricity with circular movements of the hand. Inside this spherical generator there is a battery and a magnetic rotor. You have to earn the charging of the cell phone battery by moving. The clear advantages are the independence from power outlets or direct sunlight.
  • InStep Nanopower: In the USA, researchers at Wisconsin-Madison University are working on a shoe that generates electricity. Here, too, the idea is to generate electricity with your own muscle power, regardless of location. The whole thing should work through a conductive liquid in the shoe sole. Gas bubbles in it generate electricity when you move, which can be passed on to your smartphone via a USB connection on the inside of the shoe.

It is not clear whether these alternatives are actually comparable to a power bank and are suitable for you. A closer look at these options would, however, go beyond the scope of our test.

Types of 10000mAh Power Banks

Would you like to buy a power bank with 10000mAh? Then you are spoiled for choice between five different types of power banks.

  • Standard 10000mAh Power Bank 
  • 10000mAh Wireless Power Bank  
  • Outdoor 10000mAh Power Bank 
  • Solar 10000mAh Power Bank 
  • 10000mAh Powercase 

In the following section we would like to make your decision easier by showing you the respective advantages and disadvantages. Depending on which devices you want to charge where, another type is suitable for you.

Standard 10000mAh Power Bank: Advantages & Disadvantages

The “normal” power bank is a mobile, external accumulator, usually in the form of a box or a tube. With such a power bank, you have the option of charging your smartphone, tablet or other devices without a socket, even when you’re on the go or on vacation.

Depending on the capacity (of the power bank and the device to be charged) and the number of built-in USB outputs, you can even charge several devices at the same time or charge one device several times.


  • Stored electricity available at any time regardless of location
  • Usually more capacity and cheaper than an exchangeable battery
  • Multiple devices can be charged at the same time
  • Small power banks even fit in your pocket


  • Can only be charged at a socket
  • Sometimes a bit unwieldy and heavy with larger capacity
  • A cover is necessary for targeted protection

10000mAh Wireless Power Bank : Advantages & Disadvantages

With a wireless power bank, as the name suggests, you don’t need a cable to charge your smartphone. However, provided your smartphone has wireless charging capability.

If this function is available, you simply place your smartphone on the power bank and it is charged using induction. Almost everyone knows the principle e.g. of electric toothbrushes. These are simply plugged into the charging station without a cable and inductively charged there.


  • Simple application
  • No cable or adapter necessary
  • Connections are not worn out


  • Less capacity available due to increased energy consumption
  • Charging takes significantly longer than with a cable
  • The device must lie quietly on the power bank

Outdoor 10000mAh Power Bank: Advantages & Disadvantages

The outdoor power bank is characterized by its robustness. It is perfect for your adventure on the go as it is well protected against dust, splash water and bumps. In some cases, manufacturers even offer them as completely waterproof, with integrated cables, solar panels or built-in flashlights.


  • Protected against scratches and minor bumps
  • Waterproof
  • Partly with an integrated flashlight
  • Available in combination with solar panels


  • Often rather unwieldy
  • Weight mostly higher than normal power banks
  • Charging via solar panels takes a relatively long time

Solar 10000mAh Power Bank: Advantages & Disadvantages

A solar power bank is equipped with solar panels. There are those with a panel on the normal box or those with which you can fold out several panels.

Therefore, a solar power bank is very useful and just right for you if you are an outdoor lover and want to go longer without a socket.


  • Environmentally friendly
  • Can also be recharged without a socket
  • Even more independent than with a normal power bank


  • Sufficient sunlight must be available
  • Battery life is shortened by the heat in the sun
  • Powerbank takes a long time (usually 24 hours and more) to be recharged

10000mAh Powercase: Advantages & Disadvantages

A power case or a battery case is a smartphone case with an integrated power bank. The power case is firmly attached to the smartphone like a standard mobile phone case and thus provides additional protection against scratches or if your smartphone should fall down.

The mobile phone is connected with a plug that is built into the case. No extra cable is necessary here.


  • Power bank and protective cover for your smartphone in one
  • No extra device has to be connected
  • No extra cable necessary


  • Extra weight
  • Makes the smartphone bulkier and bigger

10000mAh Power Bank: Purchase Criteria

In this chapter we will show you which aspects you can use to decide between the multitude of possible power banks with 10000 mAh.

You can compare the external batteries with the help of the following criteria:

  • USB Outputs
  • Smart Charging
  • Height & Weight
  • Display / LED Indicator
  • Warranty

In the following we explain in each section what is important for the respective criteria.

USB Outputs

As mentioned above, there are power banks with which you can charge several devices at the same time. Accordingly, these have several USB outputs. The USB type also plays an important role.

Before you buy, think carefully about what you need a power bank for and what you want to use it for. If your smartphone already has a USB-C connection, you will of course also need this connection (or an adapter) on your power bank.

iPads and iPhones also have different connections than your e-book reader or your Bluetooth speaker, for example. Pay attention to which devices you are likely to charge most often with the power bank. An adapter may then be sufficient for devices that are used less frequently.

Would you like to be able to charge two devices at the same time? Then choose a power bank with multiple USB ports. These are very practical, but you shouldn’t forget that the power bank should then have more capacity than the two devices combined.

Smart Charging

Do you travel a lot and want to have your power bank ready for use again as soon as possible? Patience is not your strength? Then you cannot avoid opting for a power bank with Quick Charge function or Power IQ technology.

As already described above, a special procedure and a special power supply ensure that your power bank is charged much faster than in the normal way. It is therefore about intelligent charging.

Here, too, of course, the capacity plays a role, the more the longer the charge takes. But: With this feature, charging your power bank is definitely more fun!

For comparison: An iPhone 7 Plus without fast charging can charge around 32% of the battery in 30 minutes. An LG G5 with Quick Charge 3.0 uses approx. 61% of the battery in the same time. Almost twice as much!

The Power IQ function is also about how quickly your power bank is charged. Using charging protocols and a controller, the power bank “asks” the connected device which device it is exactly.

Thus, the Powerbank knows through Power IQ whether it is an iPhone, iPad, Samsung Galaxy or another device, for example.

The Power IQ technology ensures that the respective device is loaded with the individually optimal settings. This in turn also enables the device to be charged as quickly as possible.

In summary, we can definitely recommend the Power IQ and Quick Charge technologies. These not only save an enormous amount of time and thus offer a certain level of convenience, but also protect the battery through intelligent charging that is adapted to the device.

Height & Weight

When it comes to size and weight, you will probably opt for devices that are as small and light as possible, since the main purpose of a power bank is charging on the go. However, the two variables also depend on the capacity.

Of course, it also depends on whether you want a very handy device in your pocket or whether you still have space in your backpack and don’t have to lug it up the mountain for kilometers. As is well known, every gram counts here.

In general, power banks move between 130 and 500 grams and are between 10x2x2 cm and 18x8x2 cm in size. The largest dimensions and the highest weight are more likely to be found in power banks with a capacity of 20000 mAh and the smallest dimensions and the smallest weight in power banks under 10,000 mAh.

A power bank with 10000mAh is therefore usually roughly in the middle of the specified data. In the meantime there are manufacturers who offer a power bank in “ultra slim”, which means that they are extra thin with approx. 6-9mm.

These are also equipped with 10000mAh capacity, but you have to note that some of them are only suitable for certain devices.

Display / LED Indicator

Power banks with LED displays or displays are available in stores. Almost every power bank now has at least a small LED display through points of light. So you can see how much of the battery is already used or charged. This is definitely an advantage for planning, battery life and gentle charging.

If you want to know more, a power bank with a display is an option. The display shows, for example, the charge level and the electrical power in volts (voltage) and amperes (current).


Another important aspect for you when making a purchase decision can be the guarantee. A power bank should stand by your side for a few years. If your newly purchased power bank is defective after just one year, you may be annoyed for a long time that you did not choose a longer guarantee.

Sometimes there are similarly good power banks with very different guarantees (e.g. 12 months, 18 months, 24 months). Here you have to weigh up which aspects are most important to you personally. Of course, it is recommended to choose the power bank with the longest guarantee if the equipment and price are comparable.

Facts about Power Banks

What is the best way to store my 10000mAh Power bank?

Storage is when you don’t use your power bank for several days and keep it somewhere. It is important here that the external battery should never be fully charged, but should never be completely discharged when you store it. Both conditions lead to damage to the battery cells.

In very cold or very hot temperatures, it is also advisable to take good care of your power bank. In principle, temperatures between -20 and +60 degrees Celsius are allowed, but this is not recommended if you want to have something from your device for a long time.

The combination of a fully charged battery and high temperature is deadly for the battery cells, so to speak. This leads to relatively quick damage. One should consider this case especially in summer. It can get extremely hot in pockets and especially in the car.

Our recommendation is a little cooler than too hot. Normal room temperatures of just over 20 degrees Celsius are perfectly fine. The temperature should not be below 0 degrees Celsius for several days.

If you don’t need your power bank for a longer period of time, it is recommended that you check the charge level regularly (approx. Every 3 months) and recharge it if necessary.

If you take these criteria to heart, you can extend the life of your power bank with little effort.

Should I always fully charge the power bank?

Opinions differ on this question, but we recommend that you only charge the power bank as much as needed.

Even with the very first charge, it is not necessary to fully charge the power bank once. Unless you need full capacity.

Should I regularly discharge the power bank?

No! In this case, the battery cells can be damaged for a long time, so that the total capacity is no longer given or the general service life of the device is shortened.

As explained above, it makes sense to regularly check and recharge the power bank even when it is not in use.

Are there any power bank accessories?

Power supplies

As already mentioned, power supplies are usually not included. If you don’t want to use the power supply unit of your smartphone or tablet, you will definitely need a power supply unit to charge the power bank.

In every electronics store or online shop such as Amazon can buy a power supply. The correct connections and a possible QuickCharge function must be observed. The cost is between US$5 and US$15.


Bags for your power bank are available between US$8 and US$20 in different sizes and colors. These are recommended if you don’t have an outdoor power bank.

So you can protect your normal power bank against dust, bumps and water or simply keep it in your bag with suitable accessories.


Adapters are another accessory. As mentioned above, it may be that you e.g. has a power bank with a USB-A connection and your new smartphone has a USB-C connection.

In addition, devices from Apple, for example, sometimes have different connections. In this case, there are small adapters that are simply plugged onto the cable.

Adapters for your power supply can also be essential if you are planning a trip to the USA. The German plugs do not fit into the socket here, but with a small attachment your power bank can also be charged as normal.
