AC to DC Converter 12V Power Supply: Universal SMPS 120V AC to 12V 50A 600W DC Converter Power Supply Transformer Driver Adapter for RV,Pump,LED Strip, LCD Monitor

Amazing can power a car amo

Works great! I use it to operate a Harbor Freight 2500 winch. I keep it in an old tackle box, and just open the lid on the tackle box and plug it in. Runs quiet and stays cool. Good purchase.

Excellent product works for posting car audio/car systems

Does what I needed it for... powering 12vDC compressor. In line 20amp fuse is nice.

It's exactly what I needed to power my diesel heater. I got tired of rotating batteries to keep the heater running. When it's cold outside, the lithium ion batteries don't run too long. The diesel heater showed that needed 10-12 amps and this unit can handle 30 amps. I connected the leads to the unit and turned it on. Then I started the diesel heater. The heater starts by heating up the glow plug and this is supposed to be the highest amperage draw. Then, you hear the click-click of the fuel pump. Finally you hear it fire up inside the burn chamber. I ran it non-stop for two days during theVortex. Polar vortex (cold snap). It turned off when it ran out of fuel. I'd fuel it up and start the Vevor heater up again. I have been very happy using it. If you want to take the 12v battery and switch to a wall outlet, this is what you need.

Product was as described. Well packaged and not damaged. Power supply is well made. I like the accessories that came with it. Allows a multitude of ways to hook up devices to it. Works great powering a 12 volt dc submersible pump.

Not exactly the cheapest DC supply I could've bought but for sure the one with the most ac noise I've ever bought. Thing dumps so much ac current you can hear the 60hz frequency coming through my speakers, so now I gotta clean up the circuit the rest of the way using a diode and 2 farad capacitor to clean it up enough to run my subs without an annoying 60hz tone in the background the entire time. I'll never buy another one from them

I pulled a head unit & speakers from one of my Jeep TJ restorations during an upgrade. Thought to myself, this OEM radio and speakers are still usable, if only I could put them out into my 120V supplied workshop but alas it's 12V DC supplied radio. This unit saved the day, not only powers my 12V DC radio but a 12V DC 400W amp added into the workshop system.Anyway, very happy, and my workshop rocks with music from my Iphone via bluetooth or via the radio's antenna mounted above my shop. Pulling well less than the 30 rated amperage this unit is not getting hot and cooling fan has yet to engage.
