“Like many people have stated in their reviews before mine - if you’re having a low voltage warning when using your Pi, sort it with the cheapest, most reliable option and buy this official charger.
Good quality, cable is plenty long enough and I’ve had zero issues with low voltage warnings since it’s been in use with my Pi - on 24hrs a day 7 days a week.
Excellent service from the PiHut, fast delivery and great communication.”
“When I bout my Pi 3b sometime ago it came with a generic power supply, it has always been a little glitchy, until recently when I get constant low voltage warnings. Got the official Pi PSU from Pi hut and it now works great. Supper quick delivery and great price”
