Running out of battery is annoying, especially when you really need it. Thankfully, a traditional power bank can be used as a backup on the go, but Anker 633 takes it to a more serious level.

The power bank holds 10.000mAh of power, enough to charge an iPhone battery roughly two times. It’s taking advantage of the iPhone’s MagSafe, so the power bank could snap to the phone securely.

In case you aren’t comfortable with the thicker appearance, 633 still offers wired charging which surprisingly could deliver power faster.
