I’ve been waiting to get a good Power Bank so I can recharge my iPhone 6 Plus and my iPad when on the go. I didn’t want a too small Power Bank. I use my iPad quite a lot, so one of the main features it needed was the ability to quick charge at 2.1 Ampere. After comparing the different choices I decided to get a TP-Link TL-PB10400mAh Power Bank. It didn’t take long before I had to test it out by measuring the capacity and the efficiency of the boost converter in it.
