5200mAh portable USB charger for $4.59
by Mark Frauenfelder from on (#12T4G)
This deal is probably for US customers only, but it's a good one. The highly rated Poweradd Pilot X1 5200mAh Portable Charger External Battery Pack is regularly $13, but if you use code E879NFK8 at final checkout you can get it for $4.59. I just bought one, because I can never have enough battery packs.
