How to Charge Your PEAX Headlamp in the Field

Quick answer

Charge your PEAX headlamp in the field using a USB power bank and the correct USB-C cable. Always carry a backup cable designed for the Backcountry Duo's recessed port.

Field charging steps

1. 1. Check your power source: Use a USB power bank, solar panel, or vehicle USB port rated at 5V/1A or higher. Avoid using a laptop USB port in wet conditions. A power bank with at least 10,000 mAh gives multiple full headlamp charges.
2. 2. Connect the correct cable: Use the PEAX Backcountry Duo charging cable. Push the USB-C end firmly into the headlamp port until it clicks. If it feels loose, try a different cable — the connection must be snug. Test your spare cable before your trip to confirm it seats properly.
3. 3. Monitor the charge light: The headlamp shows a red LED while charging and turns green when full. Charging typically takes 2–3 hours from empty. Do not overcharge — unplug once green. Charge in your tent or pack to keep the port dry and debris-free.
4. 4. Store cables safely: Keep the charging cable in a small dry bag or ziplock. Moisture and dirt can damage the USB-C connector and cause intermittent charging. Label your cable with a piece of tape so you don't confuse it with phone cables.
