How To Choose the Best Power Bank?

There is a wide range of power banks available in the market. If you’re not careful in buying a power bank, you can end up with a fake power bank or a power bank that can only charge your device 1-2 times. Also, that can harm your devices.

Capacity of the power bank

The capacity of the power bank is an essential feature that determines if it is a good option for you. The power bank capacity is measured in milliamp-hours (mAh). In general, a high milliamp-hour rating implies a high power bank capacity.

Make sure that the battery capacity of a power bank is more than the battery capacity of your device.

The mAh of the power bank you select should be at least twice the battery capacity of your phone. This way, it’ll charge your phone two times.

Power banks available in low capacity can include units with 1,000mAh and 2,000mAh ratings. You can get a 5,000mAh portable charger for the medium size and over 20,000mAh for high capacities.

For instance, a phone with a battery of 5000mAh then, it means that mobiles battery can supply 500 milliamps of electric power in an hour. So, if circuit drains 1000mAh, then the battery will last for 5 hours as its best performance.

The input to the power bank is generally at 3.7-3.8 volts whereas the output is at a standard rate of 5V. Suppose the phones battery charges at 4.2-4.4V, and here we see a down conversion. So the user may expect a decrease of up to 25% in the capacity of the power bank.

To calculate a near exact capacity of the power bank, you can use the following formula-

(Mentioned capacity of Power bank)*3.7/4.2

Type of Battery

There are two types of battery cells used in the power banks, i.e. Lithium-ion or Lithium-polymer.

Li-ion is cheap and easily available.Li-poly is more expensive.
They have a high energy density.They have low energy density.
They have a comparatively high self-discharge level.They have a very low self-discharge level.

So, its better to go for Lithium polymer batteries instead of lithium-ion batteries as they are more lightweight, safe and good quality.


Ampere is the unit of measuring the electric current. It shows the total time taken by power bank for fast charging the device.

Usually, the standard power bank has 3.5-ampere current. Therefore power bank below 3.5A will take a longer time for your device to charge.

Battery life

It determines how long a power bank will last. Lithium-Ion & Lithium-Polymer batteries usually are affected by various factors like high temperature, ageing, and cycling. These batteries have a cycle life that is generally about 500 cycles.

High currents, high temperature, and Depth of Discharge affect battery life.

When storing a battery for a long period, it is important to charge every 3-6 months. This is to replenish the lost charge over the months.

Output port

Now most of the power banks have a built-in USB port. It also comes with multiple USB ports for simultaneously charging more than one device.

The multiple ports feature is quite common in high capacity power banks. It helps in charging multiple devices simultaneously.

Safety Certification

Select the power bank that comes with safety certification. Generally, power banks with FCC, ROHS, and CE certifications are great. Power bank with certification ensures proper circuits and safety panels quality used by manufacturers.

For improved safety & performance, go for a power bank that comes with overvoltage protection (OVP) and over-temperature protection(OTP). It ensures its longevity against spurts in current & overheating while charging and discharging.

LED Indicators

On most power banks, there are generally four LED indicators with each indicator representing 25% of the power bank battery level.

The display of the indicators generally has a specific meaning.

  • Solid
    It shows that the device is connected to the power bank and is being charged.
  • Blinking
    It indicates that the power bank is being charged. If the last LED is blinking without the power bank being plugged in that means the battery is low.
  • Off
    Power Bank is in a dormant state.

Frequently Asked Questions

1. Can power bank charge all devices?

The power bank can charge wide range of devices such as

  • Smartphones
  • Compact cameras
  • Mp3 Players
  • Tablets
  • Bluetooth Devices like Bluetooth headsets & Speakers

2. Can you use a power bank to charge a laptop?

According to the design specifications of power banks, they have a 5V USB output. This output is lower than the laptop requirement that can range from 16V to 20V. Power Banks provide the output power to charge a laptop are limited.

3. How long will it take to recharge a power bank?

The first factor that determines how long a power bank will take to charge is the capacity. The high capacity power banks require a long time while the small capacity power bank requires a short time to charge.

  • Power banks that are designed to include a voltage input rather than just a USB for recharging will charge must faster.
