    There's not much to say about this to be honest. It's a 20k mAH battery bank, so it'll charge a phone at least 5 times. It can fast charge stuff, which is nice when your phone is low on the go. Only real downside is that it takes forever to charge, since the battery itself doesn't have fast charging, and it's got 5 times the battery capacity of a Note9.

    Seems to do its job I was able to charge my Samsung 3 times to full 1 day and it still had 50% left so I think I'll be able to rely on it on days I forget my charger! What I didn't like was how big it is. It was bigger than I expected but all well it does its job so I'm happy with it!

    I highly recommend buying one of these portable chargers. I used it for 4 straight hours one weekend and it did not even budge on it own charge level, it was still fully charged itself after charging my phone and keeping a consistent plug in for my tablet as I was playing on it. And it comes with a nice little carry bag to keep it secured in.

    I normally catch these on a deal and it is one of the best investments. The quality seems sturdy. I get many charges out of it without having to recharge it. I use it for my phone, baby fan, wireless speakers, nintendo switch. Pretty much anything that can be plugged in to the usb port.

    Charged it up and home and used it while traveling. Only issue I have is that the two power out plugs are labelled differently and its not clear what the difference is. I used both and got devices charged. The green one is supposedly quicker and smarter charging but I didn't watch carefully to see how much difference it made.

    I bought this thinking I wasn't going to use it that much, and boy was I wrong. There have been plenty of occasions this portable charger has been a god send especially if you are moving like I am currently and also if you like to take lots of pictures and videos you will need this to prevent your cell battery from dying at the worst inconvenient time.
