10 of the biggest power banks money can buy

Several weeks ago, we gathered up a selection of small and light power banks. You know, the kind that weigh next to nothing and fit easily in any pocket. High portability has its trade-offs, however. The downside of small power banks is that they hold little charge. In fact, some of you did write in the comments that our picks were way too tiny for their needs. That's why today we'll be looking at the opposite side of the size spectrum. 

The power banks below are built to hold tons upon tons of charge – enough to recharge a tablet at least once or a smartphone multiple times. Yes, they're big and heavy, but they're also a valuable companion to power users, frequent travelers, and adventurers of all breeds. Just throw one of these in your backpack, and you'll be ready for action!
