UltrAspire Battery Powerpack

Races are getting longer, and as a result, so are mandatory gear lists. Many events now require backup power for your electronics, and UltrAspire's Battery Powerpack is that and more. This compact case weighs just 86 grams, charges your UltrAspire 18650 and 21700 batteries, and, in turn, serves as a charger for your other portable electronics. With the ability to charge your phone or GPS device on the move, or to store your spare batteries securely, the Battery Powerpack is worth its weight in gold when the night is dark and full of terrors.
