I'm always losing charging blocks to my husband or son. I figured that if I got special ones that could be "Just theirs" it would make my life easier. I picked thing one thinking that my husband would gravitate to it since he was the only one with a phone that takes the C usb. So far, it has been working perfectly.
The charing block is nice and compact so it isn't a big deal to take it with him. We haven't found a single cord that has any issues working with this brick, which is nice. It isn't a super fast charger but it does seem to work faster than some of the other bricks we have (with the same charging cord, of course).
I personally love that the prongs that go into the electrical outlet fold in. This makes the brick much easier to pack since I don't have to worry about making sure the prongs are protected. I also don't have to worry about the prongs getting bent, since they are either folded in or in a socket.
It was a great decision getting this brick for him.
