“I’d previously bought a micro-USB power switch cable for my Raspberry Pi 3 from an eBay seller. However, whenever I used it, my RasPi would display the under-volt warning (thunderbolt icon) in the top corner of the screen.
So I bought this cable from PiHut as a replacement; it arrived 24 hours later and has been fantastic. It’s a neat little device, it’s solidly constructed and, best of all, the under-volt warnings no longer appear. 5 stars!”
