A power bank ensures you never run out of battery at inconvenient moments, and the battery of our device drains out usually at the least convenient moments.

With hundreds of power banks featuring confusing terms like mAh, Watts (W), and ports, I wrote this article to simplify your choice.

What Should You Look For

Not all power banks are equal. They come with different ports, mAh, wattage, sizes, weights, etc. The most important thing is:

  • mAh (milliampere-hour) determines the power bank’s battery capacity. The higher the mAh, the more times you can recharge your iPad. For example, if the power bank has 20000mAh and your iPad(Gen 10) has 7606 mAh, that means you can almost recharge your iPad three times from 0 to 100%

There’s another important thing to look out for:

  • Output Wattage determines how fast your iPad will be charged. All of the latest iPads support ~20W. You can also charge your iPad with a 60W charger, but it won’t increase the charging speed. It’s important that the power bank has at least 20W output. I would recommend getting a higher output wattage, in case you need to charge other devices like laptops.

There are other things to consider – how many ports you need, how long it takes to charge the power bank from 0 to 100%, whether it supports fast charging or not and the size of the device. These are all important factors that set power banks apart.

We all know that iPads without power are nothing more than a paperweight. Having a portable power bank for the iPad on your side can put your mind at ease.

Here’s an overall rating of my best Powerbanks:

If a power bank supports 20W charging and I connect two devices, will it charge both devices at 20W simultaneously?

if a power bank supports 20W charging and you plug in two devices simultaneously, the power bank will distribute the power between the devices. The charging speed for each device will likely be shared, meaning they may not both receive the full 20W simultaneously. The exact distribution will depend on the power bank.
For example, if the power bank has two ports and mentions a total output of 20W, it might allocate, for instance, 10W to each device when both are connected.
