If it's a trusted reseller and they describe the PSU as suitable for whatever model of Pi then you shouldn't have a problem. Here in the UK/EU you could return the goods as unfit for purpose (other jurisdictions may vary).MisterEd wrote: ↑Thu Sep 12, 2019 6:54 amSome of the official retailers that sell Pis also sell there own power supplies. For example I have the following:
* CanaKit Raspberry Pi 3 Power Supply (Micro USB) - 2.5A
* CanaKit Raspberry Pi 4 Power Supply (USB-C) - 3.0A
Shouldn't these power supplies also be considered just as safe as buying an official power supply? Can't I assume that these power supplies meet technical requirements RPF has established?
In the case of CanaKit, I don't shop with them but they are well known and I doubt you would have an issue with them.
Adding to my previous post, if you have a charger that's unofficial but works then great, use it but if it doesn't work don't complain to the RPF about it.
