Portable laptop charger

The Techsmarter TSB2250 is a 20000mAh power bank built for professionals and travellers who need to run a USB-C laptop away from a wall outlet. Its 130W maximum output splits across two USB-C ports so a notebook and a second device charge together without sharing power.

Capacity and headroom

The 20000mAh cell delivers roughly 10 smartphone charges, 4 tablet charges or 1.5 MacBook charges before it runs dry. Simultaneous 100W and 30W USB-C output plus a 22.5W USB-A port handle three devices at once, though total draw cannot exceed 130W.

Bundled features

A digital LCD readout shows the exact remaining capacity so you can plan top-ups instead of guessing. Three engineered ports — 100W USB-C, 30W USB-C and 22.5W USB-A — remove the need for extra adapters when charging a laptop, phone and accessories together.
