does this lantern come on when the power goes off when pluged into electricity?
P A S Although I've never been in this situation, my copy of the Sunny Sports ad from 7/14/2010 says among other things "... Emergency ON is enabled while charging and switch is set to the high or low position ... Emergency On operation: Lights automatically during a power failure. ...". So, I'd say if the present 2013 ad says the same thing, the answer is "Yes".
If the present ad doesn't specifically state this, I'd contact Coleman for more info ... but, this company is VERY thorough, making quality equipment that lasts and/or can be repaired. I love this lantern.
BRIAN M I don't know how to answer such a ridiculous question. No you have to turn the power on manually
GINA S Not that I know of... I use this for camping
