Had a Mi 10,000mah power bank previously which I used and abused that treated me well till I ruined the usb port. Got a 15,000mah power bank from a different brand and found out it didn't even have fast charging. Instead I went back to Mi and got this 20,000mah power bank and never looked back. Does fast charging, or normal charging when using two ports. Wish it was only 15,000mah to save on some weight but it's honestly you get used to carrying it around.

I’m more than happy with this power bank. I was sceptical initially but its defiantly won me over big time. I have charged my phone and IPad at the same time and chargers the bank while charging my phone on it too. 10/10

This was amazing. used this while at the Taupo Ironman 2020. Out and about for 17 hours with live tracking of my brother who was competing really sucked the juice out of my phone. With this device I was able to keep my phone charged despite thrashing my phone. And it didn't even drop 1 bar. Was also able to charge up a second phone that was just dropping after being out all day

Works great, I'm able to charge my note 10 for about 4 times

The reason I bought this powerbank over others, is that it can power a docked Nintendo switch and charge a portable monitor at the same time, with enough juice to play for hours (perfect for travelling situations) and it has been great, a very nice matte finish on a nice clean simple design
