Vilros Raspberry Pi 4 & 400 Compatible Power Supply (USB-C) with on/Off Switch

it works

And it is the full 3a that the Pi4 needs. The switch is nice as well. I got some inline switches for my Pi3s and his one is WAY better, flat so it could be mounted if you wanted.

Having a switch is great! Very convenient if I want to turn my PI off for the night, etc. No problems with this so far after a month of use.

Ive used the official Raspberry Pi adapter as well as this one. I like the fact that this has a built in power switch. Much more convenient than unplugging from the Raspberry Pi or from the wall!

Like the switch

The product works like a charm. It provides enough power for the Pi 4, and the on/off switch is a plus.

Works as intended

Capable of running the pi in steady voltage and amperage.

Powers the new Raspberry Pi 4. The On/Off switch is a much nicer solution then removing the USB-C connector.

The switch and cord of this power supply are well constructed and felt very heavy duty. I also like that it is a toggle switch (although its unlabeled) so I can see what position it is in (e.g. before plugging in my pi).
