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

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.

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

We bought this for a Koolatron cooler this was supposed to be compatible with. We even contacted Wagan with all the details to verify this was okay to use with it. It worked at first, keeping things very cool, but got extremely hot. Too hot to even touch for more than a second or two. Then we tried using it with a smaller warmer that took even less power and didn't even provide power to the warmer.

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!

Despite the bullet in the PRODUCT FEATURES, this adapter didn't work with my car tire pump. The packaging correctly did not say it works with compressors.
