GeeekPi 18W 5V 3.6A Power Supply for Raspberry Pi 4/Orange Pi 5&5B, Type C with ON/Off Switch and Micro USB Adapter

Works great!

I purchased a Pi 4 on Marketplace and the power supply was just an ordinary usb cord from like a Samsung phone. I found out that I needed something with a higher rating because after researching, I realized the little "flashing lightening bolt" in the upper right hand corner of my display meant that the Pi 4wasn't receiving adequate power and could possible damage the unit over-time and lose/corrupt data. So I purchased this and haven't gotten the warning since. And it's nice to have an on/off switch for assurance the Pi is in fact shutdown/turned off.

This power supply adequately powers my Raspberry Pi 4 and having a power switch is nice too.

Love the added power switch, great for my Raspberry Pie build.

So far everything works perfect, I’ll see how long it will last 😅

downward compatible .

On Off button and 3 amps gets my cellphone charged quickly.

These are a must have for Raspberry Pi. The switch makes it so much easier when you need to cycle the power. These provide enough power to supply the USB without causing power draw issues.

Probably not as good as official power supply but much better than using a phone charger

I wanted a power supply that could easily power any of my Raspberry Pi collection, and this does the trick nicely.Power switch comes in handy for switching between units without having to unplug the 110 V end each time.

Works with R Pi3 but low voltage error. The Pi seems to work though.The vendor has worked with me on this issue and it was very helpful.

This works perfectly with the raspberry pi3B+ running retro pino more low voltage warningsNot much more to say. I'd recommend picking it up

Works great for the Raspberry Pi 3 B+ with 7" Pi DisplayI was getting the Low Voltage Warning and found the Pi 3 B+ actually requires a bit higher than 5 volts to operate and around 5.2V is perfect. Other power supplies drop down below 5V, around 4.9V, and will cause the low voltage warning.
