Replacement for adventure set battery


Gloworm Power Packs are lithium-ion powered battery packs designed to be fast charged using a Gloworm USB-PD (Power Delivery) charger. A 20W charger is included in each G2.0 light set.

Each Power Pack features a single USB-C port and an OLED display. The USB-C port is used with a Gloworm Power Cable to power any G2.0 light (it is also used for charging the Power Pack), whilst the OLED display provides relevant information to the user. The Power Pack can also be used as a Power Bank to charge other devices.

Silicone frame bumpers are included on each Power Pack to avoid any damage whilst mounted on frame or helmet. The Power Pack can be mounted using the included battery velcro. The velcro can be cut to size depending on the mounting location – Bar, helmet or headstrap.

The Power Pack casing is made from polycarbonate, making it very durable and resistant to breaking.
