ELEGOO AC 100V-240V Converter Adapter DC 9V 1A Power Supply US Plug 5.5mm x 2.1mm 1000mA Power Adapter Wall Charger Adapter Compatible with Arduino UNO MEGA with UL FCC CE Certificate

I ise this to power a microchip technology exp 16/32 development board. It does what it is supposed to.

These are great, I have 5 of them. Please note, they only provide 5v of power.

I bought this for the original Nintendo Entertainment System (US version).I usually like to use the original linerar power supply bricks, but in this case the internal rectifier was starting to go bad, and rather than repair it, I can use this external DC power supply to effectively bypass it and therefore help to clean up the video output.

This adapter is rated 9v @ 1A; however, at 1A I estimate a 1v sag would occur. This maybe OK, depending on your application.Testing details: The initial ("no load") voltage was 9.12v. I tested by applying a progressive load, until the voltage dropped below 97%, 95%, or 93% of the initial value. Under these criteria, the functional limits are 350mA (97%) or 500mA (95%). At 800mA the voltage had dropped to 8.46v (93%). The manufacturing quality seems good. (Label states manufacturer is Shenzhen Sunshine Tech.)

I purchased this for my Hue Go light, but does not fit. Buyer beware, I searched online for a good bit to find one, and after a Google search of “hue go light adapter,” I was sent to several Amazon pages with generic AC adapters. I took a chance with this one and it was a fail. Admittedly, I even tried to “fiddle” with it to see if I could get it to fit, but there’s just no way to do it safely. I contacted Hue and asked where to find a replacement, but their response was since my unit was past warranty, I would simply have to purchase an entirely new light. The adapter itself is just fine, and I’m sure I can find another device it will work with, so it’s not a total loss: just disappointing for being pointed in this direction to find a dead end.

Did not power it on

High quality adapter
