Why It’s a Smart Everyday Carry
Most power banks either charge fast or charge multiple devices well — rarely both. The 4i manages a solid middle ground: its Power Delivery support means compatible phones charge noticeably quicker than with a basic 10W brick, while still letting you juice up three devices at once without overheating drama.
The 12-layer protection circuit is a quiet but important detail too — it guards against overcharging, short circuits, and temperature spikes, which matters a lot for something that lives in your bag getting knocked around daily.
