Koolatron Multi-Purpose Adapter 110AC to 12 Volts DC ( Model AC-15)

I just received my unit and looked for the other 2 adapters that it shows in the picture. There is only the 1. Why is there a picture of 2 plugs ? ? ? ? Can another multi car adapter be pluged into this ?
So that I can be charging up to 3 items? This lacks through information to use this. When I plug my phone into this and it doesn't work it will go back. There is no phone number for customer service???

We've had a family reunion and had our new kooler plugged into this for 6 days now and it works perfect and it doesn't overheat at all. We love it and would recommend it to anyone. We also used it in our vehicle's 110 volt recepticle. Perfect there too.

This adapter plugs into the wall and turns out 12volts just like your in-car plugs. It is effective and looks reliable (I haven't had it long enough to rate lifetime). It does get pretty hot, so you need to be careful not to let the cords sit on top of the adapter while in use

The adapter made it possible to take the cooler along with its contents into our motel room every night, saving money on breakfasts and lunches while keeping things safe and cool.

it takes the magical energy in my wall and runs my cooler every time I plug it in.
