The RAVPower 6700mAh is a hybrid: a power bank with a built-in dual-port USB wall charger, so it plugs straight into an outlet to recharge itself and your phone at the same time. It outputs up to 3A total across two ports (2.4A per port max), enough to fast-charge phones and charge a tablet. That makes it a one-piece travel charger, unlike plain power banks that need a separate adapter and cable. It suits commuters and travelers who want one brick for the wall and the road; the trade-off is modest capacity and no USB-C.
