The charger delivers up to 30 W output through a USB‐C port — enough to fast‐charge many modern smartphones, tablets, and some smaller/lower‐power laptops that accept USB‐C charging.
It supports standard fast‐charging protocols like PE2.0, PD 3.0, QC 3.0 — which helps ensure compatibility with a variety of devices (phones, tablets, and possibly some laptops).
Because it’s compact and Type‐C, it’s convenient for travel or everyday carry — you just need a compatible USB‐C cable to plug into your device.
It’s marketed as a charger that “supports laptop charging” (on sites selling it), which suggests that the designers expect it to work with at least some laptops with USB‐C charging ports.
