Usually, there is at least one USB port, but there are also other devices that come with more than one outlet for discharging electricity, such as the Anker PowerCore 20100. It’s possible that not all output ports on your power bank deliver the same amount of power. You can get various output values such as 1A, 2A, 2.5A, etc. The higher the Amps the faster your devices will charge. So if you want a fast charge use the port with the highest output.

Compared to the higher-rated 5,000 mAh charger on our list (the Poweradd Slim 2) Anker PowerCore 5000 lags behind on speeds. It only refueled 62% of the iPhone 12 in the first hour of charging, which is the second-lowest score on the list. The best power banks we have tried have all come from Anker, but that doesn't mean Anker is the only brand you should consider.
