Oh man, this is probably the best giveaway you guys have done yet! I WANT IT. Especially since this one uses Lithium Iron Phosphate batteries, which are safer and last a lot longer. For something this big, it needs to use this, otherwise I'd be worried about it taking my whole house down with it if it caught fire.
I have a smaller Anker Power Station for emergencies in severe thunderstorms/tornadoes and ice storms. Basically to keep the phones charged, maybe the iPads to occupy the kids in the dark. Depends how bad the storm is as to how long the power will be out. I have a small solar panel for it but that doesn't work well if it's cloudy or it's a prolonged storm.
But this thing? If I won it, I would be tempted to build a 4X4 camper around it using an old cargo van. Well, maybe if used car prices come down. Would make an awesome generator with some solar panels on the roof charging it while driving. And I would also make the ultimate severe storm backup without using fuel. Living in the midwest we get power outages any time of the year because you never know what the weather will throw at you.
