Heavy Duty 180W/15A AC to DC Converter,BUENNUS Convert 110V-240V to 12V Car Cigarette Lighter Socket Adapter AC DC Power Supply US Standard Plug for Car Refrigerator Vacuum Cleaner Air Pump

I needed an auto tire pump for home use. Why drive to a local tire inflation site and find it not working or costing way too many coins? Now I air up my tires at home. Works great!

Have been using this now for a few weeks and haven't had any problems. I am using to charge my old smart phone, run a 12 volt 6 soda can portable cooler, charge a 12v portable usb/110volt AC inverter and to maintain a charge on an emergency flashlight, all at the same time. You can hear a very slight sound from the cooling fan, it is to faint to be of any concern. The case and wires stay cool to the touch. It is my 3 output adapter and wires that are slightly warm. The actual power supply is built sturdy, well designed and very safe. Very happy with this purchase and I highly recommend if you are looking to power 12 volt items in your home that have a cigarette lighter plug.

The supply gave the full 12v amperage most store models are limited to half or less of the amperage

This converter is really lightweight compared to others with the same rating. There's a cooling fan inside that turns on when the current flow increases. The heatsink inside is fairly small and I assume it would get really hot without the fan.I bought this to run a 120W compressor, so I really didn't need 180W, but I did want something capable of supplying 120W continuously for 20 minutes or so without risk of burning itself out. This converter ran my compressor for 20 minutes straight without overheating. It didn't even get very warm. At, first it had a hard time holding the plug in the socket. I checked the inside of the socket and it was not very slick (which is good), so I used sand paper to rough up the contacts on the plug and that fixed it.When supplying 120W to the compressor, it is pulling 192W from the A/C, so it's about 62% efficient at 66% load. I don't think this is necessarily a problem, but it certainly could be if the cooling fan fails. Especially since it would need to dissipate around 120W of heat when supplying it's full load of 180W. I also measured 3W, 5W, and 10W loads and the efficiency is less than 60% at lower loads. That's also how I noticed the fan doesn't turn on when the current is low.

Needed a power converted, got a power converter.

F'ING GARBAGE!!!!!

This power supply is not very well regulated. When only drawing 8 amps the voltage dropped to 11.2 volts

Was as expected
