Description
The Gloworm Power Pack (G2.x) is a high-capacity, USB-C PD fast-charging lithium-ion battery designed for extended rides and demanding conditions.
Featuring an OLED fuel gauge for precise battery monitoring, it’s built to keep you riding longer.
G2.1 is an improved design of our G2.0 series, introducing an enhanced integrated power cable system with a keyed 3-pin connector that delivers superior durability and a secure, weatherproof connection compared to the previous G2.0 standalone USB-C cable.
You’ll still enjoy the benefits of USB-C Fast (PD) Charging, now with added reliability for demanding riding conditions.
The Power Pack 5 is ideal to power a helmet-mounted light, as the smaller battery pack and easily be strapped to the rear of the helmet. It can also power a handlebar light, though it will have less power than the Power Pack 10.
