Campus111 via eBay offers the 12,000mAh USB External Battery Pack
in White for $14.38
for shipping. That's pennies under our mention from a week ago, the best price we've seen for any 12,000mAh portable battery charger, and $2 under the lowest price we could find for a comparable battery pack elsewhere (outside of the price below). It comes with several adapters suitable for most types of charging ports, including iPhone, iPad, HTC, and other smartphones.
A close price: Star-Doo via eBay offers it in Pink $15.98 with free shipping.
