    It's a fine charger when you're not around an outlet, but don't expect it to be a fast charge just because it's a usb-c > usb-c. I often have to put my S-22 ultra on airplane mode just to get a fast charge out of it. It's not a big deal, but I've been noticing that you're not getting a good charge if you're on the phone while charging. At home to charge the unit takes a good bit of time. This unit definitely isn't charging fast to recharge. So make sure you plug it in to recharge as soon as you get home. I use all usb-c to usb-c, so I know it isn't the wires I'm using.

    Bought two of these, one for myself and one for my wife. I've only used it once so far but I'm impressed with the build quality and the digital battery level screen is a nice addition.
