15,000mAh battery pack for $14
by Mark Frauenfelder from on (#RP1B)
This is the best price I've seen for a 15,000mAh battery pack. (Just two years ago I paid $100 for a 6000mAh Mophie Juice Pack Powerstation Duo.)
If you use code RJTZMPYG you can get the Kmashi 15,000mAh battery pack for $14 on Amazon. It's got dual ports so you can share its juice with a friend or spouse who isn't as prepared as you.
