I got this response back from the seller:
The unit has been tested for almost an year with an Ipad 4 in an EC155. working great!
Although it will not reach the maximum charging current 3A, All Apple devices does have a detection for the power supply. In this case, the ipad will detect this power supply, and charge with a current of 2A. so you will be within the limits of the power supply. the larger the divice is, the longer it takes to be fully charged.
The temperature should not be a problem. For apple devices, the power supply will not be charged at full current. and the housing will retain full strength till 60°C/ 140°F (pla melting temperature is 180°C/350°F)
I hope that you`re reassured. if you have any more questions please let me know.
Seems reassuring. It's a very odd item to find on eBay but if it works thats awesome! I'm going give it try on my EC-130B4. I'll let you know if I end up tossing a flaming ball of plastic out of my sliding window...
