Xiaomi Mi Powerbank. Xiaomi is known for its overall good and well-priced electronics has continued what it is known for in their Mi Powerbank. Packing in 20,000 mAh and a USB-C Port that can deliver 45W of power. Xiaomi’s power bank isn’t the fastest but it will get the job done for most ultraportable laptops. I have two dell laptops, one is an XPS 13 45W USB C charger and another dell with a 60W barrel charger which also supports USB C charging. The Dell XPS is unable to charge with my 20W charger from my Pixel 3a phone, but the other dell laptop is able to charge with the 45W dell charger (although there is a warning that the charging is slow).
