BRAND NEW WAGAN 9903 5-Amp AC to 12V DC Power Adapter EL9903

Does the job but the box in the middle runs a little too hot. I'm using it for my 28qt iceless cooler. I believe these type of cords do that but it's just a little hot so I'll be watching it.

I bought this in connection with a Wagan 12v cooler, so I could pre-cool the unit and contents overnight before I put it in the pickup truck for the day's drive. Filled the cooler with soda cans at room temp and plugged the power adapter into the 120v wall outlet. The room temp was 65F and in the morning the contents of the cooler were 30F. Fortunately the soda didn't freeze at 30F, but it showed the cooler 110v adapter could do the job perfectly.

A lot cheaper than the coleman brand one that I was going to order from coleman. Only issue is it gets very hot. But I can't remember if the coleman one that came with the cooler got hot or not

Though this device does convert AC to DC power, it did not provide enough power to operate my auto tire/raft pump, although any 12V battery supplies more than ample power. I had to return it for a refund.

Use it to power my Fan-Tastic Endless Breeze fan when running AC power in the RV. A little pricey, but well built and sturdy. Looks like it will last a long time. Would definitely recommend.
