Does what it's desinge to do!
It's a small "wall wart" device that works fine to charge a boom box. However, the USB-C connector cable is NOT removeable from the wall wart.

Necessary for a Pi
I was wondering why my OrangePi would hang up every so often. I was using a regular phone charger plug with a usb. The plug itself wasn't supplying enough juice. This solved my problem and my Pi no longer hangs up. It was definitely undervolted using a smartphone charger.

Great power supply for Raspberry Pi 4
Replaced a phone charger and cord with this wall wart PSU. Solid power for my Pi and the cord length is better than what I had with the repurposed phone charging components.

Impeccable
It looks and works exactly as described. It is somewhat more voluminous than the original Raspberry Pi source because it is more powerful. Quality looks very good. No more “low voltage” messages. 😃
