Because the headlight itself doesn't need to be recharged, you can permanently bolt it to your fork crown at just the right angle, or use the handlebar mount for easy removal. Specifications Headlight mounts to handlebars or bolts to fork crown Precision lens focuses beam onto the path in front of you, not into the eyes of oncoming traffic/riders Weatherproof machined alloy body 350 lumens / 100 LUX 8+ hrs/16+ hrs runtime on 10k/20k mAh power bank Carry multiple power banks for multi-day journeys off the grid Store power bank in handlebar bag, frame bag, basket, or just strap to your stem/top tube with a Voile strap 115cm/45 inch cord with USB-A plug Power bank sold separately * Why USB-A?
