“This is one of the best power supply units that I could buy. First you know that, being the official product it will be compatible with the pi4 (we all heard about those compatibility issues), and second it is reliable. I've had the pi working 24/7 and I haven't had any power issues or anything negative to say about the PSU. Its a bit more expensive than its Chinese counterparts, but in my opinion, it's certainly worth the difference. The only downside to it is that design could be taller and slimmer, because when I put this on the extension outlet, it occupies a bit of the space reserved for the plugs next to it, so if you have a 3 output extension, and you plug it in the middle one, either the other two plugs are very slim or those two outlets become useless. If this small detail is irrelevant to you, than I would say that recommend this in a heartbeat to anyone buying a pi4.”
