8-Pack USB Wall Charger Block, FiveBox 2.1A Dual USB Port Wall Power Plug Adapter Cube, Fast Phone Charging Block Charging Box Brick Power Base Charging Station Phone Charger, Black

These are good USB A wall chargers. I bought them because they have two ports that I can use at the same time, and for the unique colors. Compared to other two-port plugs I have their size is similar, which is a bit large. This, as with most two-port wall chargers, is only a factor when plugging two of them next to each other in a surge protector or power strip. The advantage is that I try to have a plug in each room so we don't end up losing them and with the colors it's easy to identify if sticky fingers took it from it's assigned wall plug.
