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. Available in two capacities: Power Pack 5 (5,000mAh) for lighter setups and helmet mounting, and Power Pack 10 (10,000mAh) for maximum runtime.
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.
Compatible with all Gloworm G2.x light systems with external battery options, including G2.0 and G2.1 series.
