How to Buy a Perfect Powerbank Like a Pro?


Tablets and smartphones are designed to be effectively portable devices that work like computers. However, these multi-talented and advanced gadgets work with a batterie externe. While we await smart devices that need no extra power support, we would rely on external batteries.

What to consider before you shop for your power bank?

Capacity, weight, shape, and size are what you should think of before buying your power bank.


  • The capacity of a power bank is measured in milliamp-hour (mAh), which tells you the charging capability of a power bank.
  • The higher the mAh, the more energy it can offer a device. You should consider what you want to power with the gadget and know their mAh strengths before you buy your power support.

Size and weight:

  • The higher the mAh, the more the size and weight of the power bank. The smaller mAh power banks are portable and can move easily with you.
  • However, the heavy mAh gadgets need you to keep them steady.

Shape and style:

Style and shape have little to do with capacity but more with style and personal preference.

  • Match the charge capacities:You should consider the capacity of the gadgets you want to charge with a power bank.
  • Power bank output charge current:Learn the rates at which your power bank can charge your devices.
  • The number of ports:The number of ports in your power bank is important and gives you an idea of how many devices you can charge at once.

Lithium-ion vs. lithium polymer: 

  • We have two types of battery technologies, namely, lithium-ion and lithium polymer. The former is of a higher power density but lacks a memory effect. Lithium-ion lowers the cost than lithium-polymer.
  • Lithium-polymer batteries are more flexible, robust, and lightweight. However, these batteries come with a lower chance of suffering from leaking electrolytes.


The cost of a power bank should be considered when searching for the right power support gadget.

Connecting Devices to a power bank

Most of the power banks come with the following charging inputs:

  • USB-A: The USB-A comes in a rectangular-shaped port that can fit every hard drive, TV, laptop, hard drive, and gadget of the last 10-15 years.
  • Micro/mini-USB: This type of USB variant is ideal for portable devices, including smartphones.
  • USB-C: The USB-C is a better version of the USB-A and preferred because of its versatility and size.
  • Wireless: You can charge your device wirelessly when you place your smart device on this type of power bank.

It requires your smartphone to accept its wireless charging.

What makes a fast charge happen?

For your device or phones to achieve a fast-charge, you’ll need the following:

  • A device that will accept a fast charge
  • A compatible power bank
  • A compatible cable
