There are a lot of external battery packs for the iPhone, fewer still for the power hungry iPad, and even fewer for laptops because of the non-standard plugs. So I was very excited to see the PowerSlate from Nexiom at CE Week in New York City last month.
Not only does this one device offer over 13,000mAh of power (almost ten times that of iPhone battery cases) it can provide power for an iPad, and even most laptops!
