Baseus Picogo 10000mAh Power Bank | 45W

The first thing I have to say about the Baseus PicoGo 45W 10000mAh power bank is that it's compact. It has the same dimensions as a credit card (see photo), but is about 1-inch, or 2.5 cm, thick. This little power bank is capable of recharging my iOS phone, my iOS tablet and my two Windows laptops, which require 45W of charging power. I noticed that there's some understandable confusion regarding this power banks capacity, due to a reference to its battery capacity being 5,000 mAh. I found a website that disassembled the Baseus PicoGo 45W power bank. This power bank uses TWO 21700 cylindrical Li-Ion cells (see provided photo). Each of these TWO cell have a capacity of 5,000 mAh. This power bank's total actual capacity is, as stated, 10,000 mAh. While charging my cell phone and any of my tablets, the PicoGo power bank did not heat up noticeable. The only time its temperature increased noticeably was when it was providing a full 45W of power to charge my two Windows laptops. I was able to confirm this charge level using a USB volt/amp meter. The PicoGo will display a yellow lightning bolt icon, when it's providing fast charging. If you're going to opt to use another USB cable, other than the one that's build into this power bank, you should invest in a high-quality cable. This will ensure that this power bank is able to provide its maximum 45W charge level when connecting it to a laptop. If your laptop requires more than 45W of charging power, obviously this power bank will not be able to charge it.
