Find out how we selected and ranked the products.

1. Features: Most important purchase criteria for power banks

1.1 Capacity

The more the mAH (Milliamp Hours) the more will be the power bank capacity. The power bank should have double the charging capacity than what a device needs. Suppose a device (say a smartphone) of 1500 mAH battery needs a power bank of 3000 mAH battery. Any power bank lesser than this capacity will not be as efficient. Plus a better capacity of the power bank implies that it can be used to charge multiple devices at the same time.

Plus a better capacity of the power bank implies that it can be used to charge multiple devices at the same time.

1.2 Connectivity Options

Capacity is linked with the feature -connectivity options/ connectivity ports. More ports mean you can charge more devices at the same time but then it also depends on the capacity of a power bank. Some power banks even come with USB ports adding more value to the product.

1.3 LED Indicators

LED indicators are all over the place and they can indeed be a great addition to your power bank to track multiple things. They indicate the charging percentage and battery level. Also, they act as power (on/off) indicators. Many prominent brands had LED lights embedded in the power banks and it's a feature worth having in it.

Also, they act as power (on/off) indicators. Many prominent brands had LED lights embedded in the power banks and it's a feature worth having in it.

1.4 Safety Factor

Despite all good things, the power bank has a limitation as well.

Most users have a habit of overcharging devices and this nature brings two disadvantages. If you are using an inferior quality power bank then not only you will damage the battery of the device charged with the power bank but it can also result into power bank battery being exploded due to short circuit and excess heating.

Hence, it is also important to go for with more stable elements (such as lithium-ion batteries) for greater safety.

Hence, it is also important to go for with more stable elements (such as lithium-ion batteries) for greater safety.

1.5 Ampere Count

Ampere count is also one of the prominent factors to consider while buying a power bank. It is the amount of electricity that is to be passed from the power bank to charge your device. The device which is being charged only takes the required amount of electricity and then the connection shuts off automatically.

For instance, if a device takes 5 amps of electricity (power) to charge, it will still take 5 amps only irrespective of the actual power supplied by the power bank. If the power bank fails to supply the minimum amount of power required to charge a device, then the device will charge either slowly or will not charge at all.

1.6 Cables

It is imperative that you use a designated cable to charge your device with a power bank as it significantly determines the pace of charging. This is why a cable stands as an important element while buying a power bank.

3. FAQ: Learn more about the details

3.1 Are power banks safe to use?

Yes, power banks are absolutely safe to use until some malfunctions and defects in lithium-ion batteries lead to an explosion. However, such a thing is very unlikely to happen.

It is always recommended not to trust any random brand and fall for a lower price because they usually offer you defective items/parts and products.

3.2 What does mAH mean?

mAH is an indicator of the energy capacity of a power bank. It is always safe to go for a power bank that has equivalent or higher capacity than the device you want to charge. 

For example – for a phone with 3000 mAH, use a power bank that is of a higher capacity viz. 3000 - 5000 mAH.

3.3 Do power banks damage battery?

Power banks never do any harm to your device’s battery until and unless it is made of bad quality. Just ensure that the power bank has perfect compatibility with your device and the device is getting charged properly.

3.4 Is a 10000 mAH Power Bank Enough?

It entirely depends on the phone you are going to charge using the power bank. However, considering most phones have 3000 to 4000 mAH batteries, 10000 mAH capacity should suffice.

4. How-To: Usage hints and care instructions for power banks

4.1 How to take care of a power bank?

  • Keep the power bank at room temperature as the lithium-ion battery performs the best when weather conditions are not extremes.

  • It is recommended to charge the power bank before first use and also when it is used after a long while. Lithium-ion and lithium-polymer rechargeable batteries do not like being left in a discharged state for long period.

  • The power bank should be kept away from moisture and water.

  • Keep power banks away from metal pieces like keys, lighter to avoid the risk of short circuit.

  • Power banks have delicate components as circuit boards and the battery. Dropping the power bank may cause damage to the lithium rechargeable battery element or the circuit board.
