Purchased new last year. Used sparingly for five days on the JMT last summer and no need this summer with only short trips (backup battery) on the horizon. Official ultralight solar charger of the PCT (according to the Suntactics website.) Durable. Lightweight. Waterproof. Efficient. Comes with manual, carry case and original packaging. New this charger is $115. Will sell for $60 and ship for free to lower 48.
