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.

Has power to run both Raspberry Pi 4 and Raspberry Pi 7" Touch Screen Display
I created a digital frame using a Raspberry Pi 4 and a Raspberry Pi 7" Touch Screen Display. This worked well but was constantly reporting low voltage and throttling the RPi4. I was using a 3.5 Amp power supply which wasn't quite enough. This power supply provides enough power to keep the RPi4 up to speed.

Good cord for the money
Needed something to power my wifi box without the battery the one that came with it wouldn't keep it running and with battery it would go into heat mode it fixed my issue recommend buying

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.

El cable esta algo corto
Cumple bien su función lo uso con un mister pi, el único unico inconvenientes es que el cable esta algo corto, y el cuadrito esta muy grande

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. 😃

Beware shipped unit was only rated 3amps instead of 4..
Returned for a full refund.
