Incredibly handy for travel
I loved having this charger for my summer cross-country bicycle trip. Particular out west (western WA, ID, MT, WY, ND, NE) there was little access to power. I had the "Pure Outdoor 15W, 5V Portable Solar Panel" from Monoprice that I would connect this to. Within a few hours, this can put a good amount of charge back into your battery using solar power. It actually performs an excellent job at a rather sophisticated task: boosting 5 volt USB power up to 8.4 volts for your batteryâ€”not exactly an ordinary charging task. It is also useful for long-distance rides that require a battery recharge, where you may not want to carry one of the larger Lupine chargers. I also appreciate the visual indicator that illuminates red while charging and green when finished.
