The Zero Power is a 10,000 mAh power bank that weighs just 145g and is under a centimetre thick. It's made for trail runners, fastpackers and anyone who wants to keep their phone, GPS or head torch going without the bulk.
It's built with a forged carbon fibre frame for strength at low weight. It's IPX4 rated against rain and splashes, and has a flame-resistant inner frame. Fast charge mode gives up to 22.5W, and Flextail says it takes an iPhone 15 Pro to 50% in about 26 minutes. Double-press for Smart Efficiency mode to get up to 30% more usable energy. It always keeps the last 10% of its charge in reserve for emergencies.
