On my article about working with the Surface Go, I found issue with using regular power bank that is insufficient to charge the Surface Go, to the point that it could throttle the processor when going below 20%. So right after I wrote that article, I went on to search for a power bank that support USB-C PD (Power Delivery).

However, not many power bank is up to the criteria that I needed.  The first and foremost requirement is the size must be reasonable, as I’ll be taking it around along with the Surface Go, so anything beyond 20,000 mAh is out of question.

Another thing is, I’m looking for a more well-known brand, so I avoid generic power bank that has unknown brand name. This means I’ll be looking for the likes of Anker, Aukey and other reputable company in this space. I also wanted to be able to charge the Surface Go at full speed, so the USB-C PD must be able to output at least 24W.
