Sub-Zero Energy Reserve

Conventional power banks suffer severe capacity loss or total failure when exposed to freezing temperatures. The SUMMIT 20000 maintains reliable power output down to -40°C by utilizing low-temperature resistant technology and carbon fibre thermal insulation. This ensures your vital navigation equipment, headlamps, and communication tools remain charged during winter trekking or high-altitude climbing.

Lightweight Carbon Fibre Construction

Constructed with a seamless carbon fibre composite structure, this power brick achieves high structural strength while weighing just 315g. The unibody construction provides excellent resistance to impacts up to 1.5 metres and helps protect internal components against drops and harsh outdoor wear. Its sleek profile fits effortlessly into chest pockets or pack sleeves without adding unnecessary bulk.

Versatile Dual-Port Charging

Equipped with both USB-C and USB-A ports, the SUMMIT 20000 provides up to 20W max output to top up electronic devices quickly. The bi-directional USB-C port allows rapid recharging of the power bank itself as well as fast charging for modern smartphones and devices. Dual-port capability enables flexible charging setups when managing multiple gear items off-grid.
