Anker 10,000mAh 30W Power Bank with Built-In USB-C Cable

The Anker 10,000mAh 30W Power Bank solves the one problem every portable charger has — a forgotten cable. This one has a built-in USB-C cable that folds right into the body of the bank, so you'll never be stuck without a way to charge. At 10,000mAh, it carries enough juice to fully top up most smartphones twice over, and the 30W output means your phone charges at full speed, not trickle speed. It's slim enough to toss in a jacket pocket and light enough that you won't notice it until you need it.
