Enough for a laptop
87W is real laptop charging, not a slow trickle — it keeps a work machine alive through a full travel day.

Most power banks make you choose: enough capacity, or enough speed. This one does both — 20,000mAh of charge pushed out at up to 87W, which is genuine laptop territory rather than a slow overnight trickle. The USB-C cable is built into the body, so the cable you always leave on the kitchen table is permanently attached, and it folds flat into a carry strap. A digital display tells you exactly how much charge is left and how fast it is going in or out, and the extra ports let a laptop, phone and earbuds all drink at once. Pick Black, White or Misty Blue.

The cable is attached
The USB-C cable lives on the bank itself, so the one thing you always forget is already with you.
03
Know exactly what is left
A digital display shows remaining percentage and live charging speed instead of four guessing lights.
04
Three devices at once
Charge a laptop, a phone and earbuds together without unplugging anything.
