Portable USB battery chargers come in all shapes and sizes; indeed, the smallest ones can fit in a pocket, while the bigger variety can be heftier than a hardback copy of War and Peace.
As you can probably guess, the smaller the battery, the less juice it’ll hold. A lipstick-sized portable battery won’t be powerful enough to revive a tablet, but it can generally charge a standard-size iPhone, or give a partial charge to a jumbo iPhone 7 Plus or Samsung Galaxy S7.
The biggest portable chargers, on the other hand, are often capable of charging a power-hungry iPad multiple times, or they might even be able to charge both a phone and a tablet at once.

As its name implies, the PowerTank isn’t the smallest or lightest portable battery on the block—indeed, it’s nearly an inch thick and it weighs in at more than half a pound. But the PowerTank can also fully charge a dead iPad, and thanks to its dual USB charging ports, it can charge two mobile devices at once.
