https://aussieskier.com/products/scott-patrol-e1-30-avalanche-airbag As the title suggests we've just taken delivery of Scott Patrol E1 30l Supercapacitor airbags. Quite frankly these are game changers. Canister airbags are a PITA to travel with, trust me, lithium-ion powered bags are better but not perfect. These guys can be charged via supplied power adapter, USB or even 2x AA Batteries in 20-40 mins (20 for adapter, 40 for USB or AAs), they will hold their charge for 3 months.
3 months..... I'm wondering how they get around the high self discharge rate of supercapacitors. I'd expect the charge to dwindle to 10-20% in 3 months.
Looks like they are using the 2 x AA batteries to keep the system topped off, giving the three month reserve capacity. Looks great and I want one, two grand tho.... damm.
