High capacity — 27,000 mAh (≈ 99.9 Wh). That gives you multiple full charges on a phone (or several top‐ups) — useful for travel, heavy use days, or power outage backup.
22.5 W “fast charging” output (PD / QC / other supported protocols). It supports major fast‐charging standards (PD3.0, QC3.0, etc.), meaning it can charge many modern smartphones, tablets — and other USB devices — relatively quickly.
Multiple ports — at least two USB-A + one USB-C output. That means you can charge multiple devices simultaneously (e.g. phone + earbuds + tablet) or share with a friend.
Two‐way charging (via USB‐C input/output). The USB‐C port works both to charge the power bank itself and to charge devices — more flexible and modern than older power banks with only USB‐A input.
