12V 5A Power Supply, Waysse Power Supply Adapter, AC DC Converter 100-220V to 12 Volt 5 Amp Transformer 5.5x2.1mm Plug for LED Strip Light DVR NVR Security Cameras System CCTV Accessories

Works with star64 and cheaper than the one on pine64

Great as described

Had this powering a peltzer water cooler for a couple months.I have to say this deserved a 10/10.for build quality because after I did some math and troubleshooting why the cooler wasn't getting to temp I discovered this power brick is only rated for about 60w of power and the setup I was using demanded closer to 80! It worked at its absolute limit for MONTHS before starting to fail from overheating. It worked absolutly brilliantly and is a prime cost to performance winner for its intended application.I wouldn't suggest this for a peltzer plate, but it has many other uses like in led lighting. It has good connections and is a great size for its application.

Plug and play, so long as you are plugging into the commonly used 5.5 x 2.1 mm D.C. socket. Note that the center connection is positive, which is the most common configuration, but do confirm this on your equipment before ordering.The power supply did not work for my motor application, even though the motor is rated for only 2amps. This is because motors produce an instantaneous inductive current spike upon start-up, and that tripped the built-in over current protection circuit in the power supply. Consequently, the motor would start for an instant, then shut down, then repeat over and over. I confirmed that the power supply worked fine with a less inductive load, such as charging a small battery, or operating an L.E.D. strip. For that reason, I decided to keep this unit for future 12 VDC projects. Overall, a good power supply.

Great 12v x 5A power adapter. It works well.

I design industrial electronics and was evaluating this for use in piece of lab equipment. The following discussion is a technical analysis of why this is an unsafe and unreliable product. The TL;DR version is DON'T BUY THIS PRODUCT. It is unreliable and the compliance labels on the back are a COMPLETE LIE. Critical components on the circuit board were left off for the sake of saving a tiny amount of money.Failed after only a few hours of use with a light load (12V @ 500mA). I opened the case top and took the attached photo. I found almost all of the input protection components designed onto the PCB to be missing.The AC comes in on the lower right. There is a missing large rectangular component directly across the mains. I believe this should be an MOV which clamps voltage surges to a safe level. In the shadow of the large capacitor we see a series component RT1, which I believe should be a PTC which limits inrush into the large input cap. Above and to the right there is a capacitor outline which would be the X-capacitor. X capacitors are used to minimize the effects of overvoltage surges, conducted interference, and voltage transients. They are also used to filter EMI from the mains and equipment. This is an important component which was omitted. Finally, in the upper right there is an outline for a CM choke which is jumpered across. This would help filter out the switching noise, and without this and the X-cap, there is simply no way this would pass CE emissions testing.It's no wonder the supply failed. There is only a 2A fuse between the mains and the switching controller, which is a semiconductor device and sensitive to surges and noise, which always exist on mains. Something as innocent as a heater turning off on the same circuit could cause enough inductive surge to kill this supply, which is exactly what happened in my testing. Of course they won't care, but whoever is selling this should be ashamed for leaving these components off. Those safety components are there for very good reasons and should never be omitted.

I bought this since the roku power supply(brick) failed. The cord on this one is a little shorter and the 110 side does not come out like the roku one does, but it works perfectly. I'm very happy with this one.

Very good power supply converter for my growing lights.Fast delivery, reasonable price.
