Bluetti just dropped the Pioneer Na, the first portable power station using sodium-ion batteries—designed to keep your devices running even when temperatures hit –25°C. Lithium power banks notoriously fail in extreme cold, but Bluetti claims sodium-ion tech keeps charging when others freeze up. Is this the breakthrough cold-climate adventurers and off-grid pros have been waiting for, or will sodium-ion’s reliability crack under real-world pressure? Would you trust your gear to this new chemistry? #Tech #TechDebate #BatteryTech
