“Bought this to power the Pi4 running OctoPi with the Pi Camera Module 3. Seems to be providing enough stable power,I haven't checked the it can deliver the 15W claim, but have no reason to doubt it.”
“I bought this to power the official Raspberry Pi Monitor rather than power it via my Raspberry Pi 500 so I could increase the maximum sound volume and brightness. It provides 15W (5V, 3A) which easily powers the Monitor (5V, 1.5A). I prefer official Raspberry Pi products for consistency in quality and safety. No quality issues with it or issues while in use.”
