Vilros 2.5A Micro USB Power Supply with On/Off Switch for Raspberry Pi (NOT compatible With Pi 4)

Performs solidly, no issues. I particularly appreciate not needing to deform the USB connector by constant plug/unplug cycles. Wish I'd bought 20 of these years ago...

Used to power a 3b+/Octoprint build. Works well and has a good cord length for my setup.

I was running a Pi-Star hotspot with a power supply that originally shipped with another Pi3B case. That power supply worked okay for a few months and then died. After doing some research, I settled on this one. It has an inline on/off switch as well as an RFI choke on the line. It works fine and is well worth the money.

These power supplies last! I should know I left my Raspberry plugged in and left on for two years(running a web server) and still working! What a great buy!

So far the 3 I own are RF friendly
