This powercase / charger is well designed to recharge your Ledlenser headlamp! Key attributes I really like are it is light in weight especially when compared to other power pack units, it's compact including storing of the headlamp for recharging. I also like the power status as shown in the one photo. I was able to recharge my phone with it too although the second time it didn't fully recharge. Given this, I will plan to use my powercase in the backcountry for keeping my headlamp charged only (in camp at night and carry an extra set of alkaline batteries with me in the field). One area for improvement might be to increase the powercase "charging life" although I realize this would likely increase the weight. Overall, this powercase is definitely worth the investment for use with your headlamp and will help eliminate the need to carry some extra batteries.
