I purchased this unit to power the Koolatron Compact Kooler, which uses 4.5 amps. I initially purchased the Sunforce 55520, which was a big mistake. It arrived dead on arrival and after some research I realized that it never really had the power to run the fridge, even though it boasts 5.8 amps.

However, this worked great right out of the box. My first impression was that it was definitely much heavier than the Sunforce 55520 and it seemed to cool the fridge effortlessly. I precooled my fridge for about 12 hours before plugging it in the car and the adapter never got hotter than lukewarm.

If you need an AC/DC Power Converter that will power a device upto 5 amps, go with the 5 Amp AC to 12V DC Power Adapter. You won't regret the decision.

This item works perfectly. This adapter gets criticized unfairly by people trying to run 12V air compressors. People, please keep in mind that this adapter is useful for providing a SMALL amount of power at 12V. It simply doesn't have enough power for a compressor.

Please review the following formula: Watts = Volts x Amps. If you are limited to 5 Amps on a 12V circuit, that means you can produce a maximum of 60 Watts. Your 150 Watt compressor is not going to work correctly, and may even damage the adapter.

Electric motors, such as fans and pumps usually require 3-4 times their operating wattage in order to get started. This initial load may damage the transformer if it is not designed to handle large load spikes.

This 12V 110V adapter worked perfectly to power my Coleman thermoelectric cooler that draws a continuous 4.5 amps at 12V

Worked perfectly with my igloo cooler. Had it running for 2 days in the hotel room when we went away.

There's very little to say about a power supply that works properly. I used this to supply power to my QHY8 astronomical camera, which wants 4 amps at 12 volts. I typically use it for 6-8 hours at a stretch, and while it gets warm, it does the job. This supply was reasonably priced, and it's smaller than the similar 12V DC power supply I purchased to power my anti-dew strips.

I purchased this to go with a cooler that I bought. I went on
a long road trip and needed to take the cooler into the motel
room with we and plug it into a wall socket. Worked perfectly
for me. You just plug the cigarette lighter part of the cooler into
this and then plug the prongs into the wall outlet. I wanted to keep
the cooler cool at all times to store my insulin.

I wanted to provide an AC power supply to an inflator. I have an excellent 12vdc inflator that I wanted to be able to use at work, rather than buy a different one made for 110vac. This power adapter doesn't come close to the amperage required. Once I tried and failed, I read the operater's manual for the tire inflator and saw that it required a minimum 10 amps. Oops. I have used this on other 12vdc applications and it works like a dream. Should have understood what I needed and compared that to what I was buying up front. No one's fault but mine.

I tried to operate a 12-volt fan that is rated at 2.6 Amps and the voltage dropped WAY below 12 volts-- making it severely underpowered. The adapter says it can handle 5 amps, I would hate to think what actual voltage it is putting out if you try to put that much load on it. I have used many generic branded 12-volt adapters and never seen a single one perform THIS badly!
