SUMMIT Air Ski Power Bank (8,000mAh 22.5W)

Power that keeps working when the cold shuts everything else down. A 135-gram carbon-fibre power bank that delivers charge down to -40°C, with two USB-C ports at 22.5W to keep a phone and an action cam alive through a full day on the mountain. Reliable output down to -40°C, where ordinary power banks stall 8,000mAh (28.8Wh) in a shell that weighs just 135 grams Two USB-C ports, 22.5W each, to charge two devices at once IPX8 waterproof for snow, splashes and wet conditions Carbon-fibre shell, glove-friendly button and RGB port lights USB-C lanyard charging cable built in, so a cable is always with you 28.8Wh, well within airline carry-on limits for travel Full power in the cold, not a dead brick in your pocket. Cold drains most power banks fast, and many simply stop delivering once the temperature drops far enough. The SUMMIT Air is built for extreme cold and keeps working down to -40°C, holding roughly 80% of its capacity at -20°C and around 60% at -40°C. That means a charge is there when you reach the summit or the last lift, not lost to the mountain air. Charge the bank itself indoors, between 0°C and 50°C. Sealed against snow and wet. Ski days change quickly, with falls, snow splashes and wet gloves all part of it. An IPX8 rating means the SUMMIT Air is sealed against water, so a face-plant in powder or a soaking in a jacket pocket does not put it out of action. It shrugs off the conditions that leave an unsealed power bank at risk, ready for snowy and wet environments. 135 grams that disappears in a pocket. At 135g and about the size of an energy bar, the SUMMIT Air slips into a ski jacket pocket, a waist pack or a small summit pack without the bulk. A common 8,000mAh power bank runs closer to 243g, so this saves you roughly 44% of the weight. A carbon-fibre shell keeps the structure light and strong, so you carry the power without carrying the extra grams. Two USB-C ports, charge two devices at once. Twin USB-C ports each push up to 22.5W, so a phone and an action camera top up together rather than waiting in turn. Both support PD, QC3.0 and SCP fast charging to fill devices quickly between runs. One port doubles as the input, recharging the bank at up to 20W, so the same USB-C cable powers your gear and refills the SUMMIT Air. More power from less weight. An 8.4V high-voltage platform with an active balancing battery management system moves energy efficiently and safely, reaching an energy density of around 213.3mWh per gram. That efficiency is how the SUMMIT Air packs 28.8Wh into a 135-gram body, with the management system watching over temperature, current and voltage the whole time. Easy to use in gloves and in the dark. Dynamic RGB lights on each port show where to plug in and how charging is going, so you find the port and read the status at a glance during a night ski or an early start. A single physical button wakes the four power-level indicators, so you check the remaining charge with a gloved hand rather than peeling off a layer. The cable is already attached. The SUMMIT Air comes with a USB-C lanyard charging cable, so the cable rides with the bank on a wrist loop or a clip. There is no digging for a spare cable or realising you left it at home. Grab it, plug in and charge, then let it hang from the lanyard while it works. WHY THE SUMMIT AIR OVER AN ORDINARY POWER BANK Works in the cold Delivers power down to -40°C and holds about 80% capacity at -20°C, where an ordinary bank slows or cuts out. Around half the weight 135g versus roughly 243g for a common 8,000mAh bank, thanks to a carbon-fibre shell and a high-density platform. Two devices at once Twin USB-C ports at 22.5W each charge a phone and a camera together, both with PD and QC fast charging. Built for the mountain IPX8 waterproof, RGB port lights and a glove-friendly button, made for snow, low light and cold hands. WHO IT'S BUILT FOR Skiing & Snowboarding Keeps a phone and action cam alive across a resort day, light enough to forget in a jacket pocket. Mountaineering & Ice Reliable charge at altitude and in extreme cold, where reliable power can matter for safety.

Yes. The SUMMIT Air is rated to deliver power down to -40°C, keeping roughly 80% of its capacity at -20°C and around 60% at -40°C, where many power banks stop. Recharge the bank itself in the warm, between 0°C and 50°C, for the best result. Can I take it on a plane? Yes. At 28.8Wh it sits well under the 100Wh limit airlines set for lithium power banks in carry-on baggage, so it travels easily. Always carry a power bank in your cabin bag, not checked luggage. How do I recharge it, and can it charge two devices together? Recharge it through the OUT1/IN USB-C port at up to 20W. Both USB-C ports output up to 22.5W each and can charge two devices at the same time, with a combined output of 15W. The included USB-C lanyard cable handles both jobs.
