How to Charge a USB Headlamp
USB charging is the whole point of a modern headlamp: the same cable that charges your phone keeps your light ready, and there’s nothing to leak or corrode inside like disposable batteries.
Step by step
1. Plug the cable into the headlamp’s charging port and any USB source — a phone brick, laptop, car port or power bank all work.
2. Watch the indicator: red = charging, green = fully charged.
3. Unplug once it’s green. That’s it — no app, no dock.
What the indicator light means
| Light | Meaning |
|---|---|
| Red / steady | Charging in progress |
| Green | Fully charged — unplug |
Make the battery last
A few easy habits stretch every charge and the battery’s lifespan:
Use the lowest useful setting. The brightest mode drains fastest; a softer flood covers most camp and household tasks and runs much longer — the lamp is rated around 4–6 hours per charge depending on mode.
Top up before storage. Don’t leave any lithium light fully drained for months. Charge it up, then keep it in your bag or drawer.
Keep the port dry. The lamp is IPX4 water-resistant, but wipe the charging port dry before plugging in.
