Specifications, compatibility and what to check before ordering.

Compatibility notes
Check your laptop's USB-C charging requirements before buying. Maximum speeds require a compatible device, cable and charging protocol; power is shared when multiple devices are connected. Nominal cell capacity and usable output capacity differ because of voltage conversion and operating losses. Verify airline carry-on rules before travelling with a 30,000 mAh power bank.

Questions before you buy
Can the Zero Lumin L-300 charge a USB-C laptop?
It can charge compatible USB-C laptops that accept its supported USB-C power delivery. Check your laptop’s charging requirement; each supported USB-C path offers up to 100 W under the manufacturer’s specifications.
Does 200 W mean one device charges at 200 W?
No. Zero lists up to 200 W as combined output across supported ports. A single supported USB-C path is rated up to 100 W, and power is shared when devices are connected together.
Why is the rated output capacity lower than 30,000 mAh?
30,000 mAh is the nominal cell capacity. Zero lists 18,000 mAh as rated output capacity; usable energy is lower because voltage conversion and operation consume power.
Can I take this power bank on a flight?
Airline and route rules vary. Check the battery’s Wh rating and your airline’s current carry-on policy before travelling; do not assume a 30,000 mAh unit is permitted.
