ChargeTech takes the trophy for highest crowd-funded battery pack of all time on IndieGoGo. (Yes, there's a trophy for that now. But it's nothing compared to mine for Hardest Trier and First Place for Showing Up and Going Through the Motions Today.) Small enough to fit in a pocket, and powerful enough to charge any device under 85W, including those requiring an AC, the ChargeTech Pack will relieve you of the hunt for outlets in airports and cafes.
At just 5.25" long x 1" deep x 7.5" wide, the ChargeTech battery pack packs an extremely high 18000mAh for its genre. It will charge up to 3 USB/AC devices simultaneously. The unit is available at a 31% discount for a limited time from Dude Exclusives.
