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

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.

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.

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.

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

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.

Item is as described works great

Purchased 2, both failed...thought the 1st one MAY have been my issue when wiring it up and lasted about 1 month. Decided to purchase another one since it worked fine but I could have shortened the life of it by incorrectly wiring it the 1st time. The second one was wired correctly from the beginning and only worked for about 3 weeks. Only powering LED lighting in a camper, shouldn't have had any issues...you get what you pay for I guess.

I am currently powering my single10" Audio Dynamics Subwoofer, in a ported box, following the AD schematics design, which I decided that it took up more room than I liked, and built a sealed box for a Stereo Integrity 11" shallow mount subwoofer, taking up far less room. It provides more than enough power for my Arc Audio KS300.4 car audio amp. I'm using just one set on bridged outputs for the sub, 375 watts RMS, 4 ohms, so not even taxing the power supply, It has plenty of ventilation, and after a couple hours, it's not too hot, just barely warmer than room temp. I have been wiring systems in homes and cars, so I didn't use the supplied power cables, had some 4 gage wires and connectors to wire up the amp/supply. I provides the power I need, worth the money, I like the smaller size compared to my older 12 volt power supply, and the on/off switch on the front.
