ADATA P20000D – all you need during a long journey

Updated on February 16, 2017

Recently ADATA presented 2 new external batteries (Powerbanks) with smart panels and digital displays which show the battery level. This current model (P20000D) has 2 USB ports. Each one provides 2.1A. There is the cool feature two devices to be charged simultaneously. P20000D has 20000mAh capacity, which according to the documentation assures more than 6 full charges of a smartphone or tablet.

Specifications of ADATA P20000D

The Powebank comes with 6 built-in protection circuits that prevents against overloading, overheating, high and low supply voltage. The casing of the battery withstand fire, vibration and shock. The model comes with a year limited warranty.

The model has a flashlight, which is triggered after a long press of the battery button and the same combination is used for turning it off.

My phone battery capacity is 3050mAh. Although I was using the display the charging itself from 0% to 85% took only 2 hours which is quite impressive.

Charging from 0% to 100% took 2 hours and 40 minutes

This is one of the most important characteristics of every external battery - the option to use your phone while charging it.

During this time the battery life of the P20000D fell from 99 to 78 percent. For me personally I was able to make four and half charges.

The Powerbank itself is charged from 0 to 100% for 12-13 hours.

My opinion

Very good build quality, adequate systems for protection and prevention. Also the option of using the phone, tablet while charging is very well welcomed.
