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.
When helmet-mounting a G2.0 light with a G2.1 Power Pack 10, an optional USB-C to 3-pin extension cable is required to achieve sufficient cable length.
The included USB-C to 3-pin adaptor provides approximately 40cm of cable, adequate for bar or frame mounting, but not for routing to a helmet or storing the battery in a pocket or backpack.
The Gloworm Power Pack (G2.x) is available in two capacities:
- Power Pack 10 (G2.x) (Fast Charge Battery 10Ah), with 10,000mAh capacity for maximum runtime.
- Power Pack 5 (G2.x) (Fast Charge Battery 5Ah), with 5,000mAh capacity for a lighter, more compact setup.
