For its newsletter subscribers, Newegg offers the Vantec Power Gem 3,500 mAh Rechargeable External Battery Pack in Pink, model no. VAN-350BB-PK, for $12.99. Coupon code "EMCWVWN245" cuts the price to $9.99. With free shipping, that's tied with our Black Friday week mention (which was another color and required rebate hassles) and the lowest total price we could find by $20. It features two USB ports and measures 4.45" x 2.32" x 0.59". Deal ends December 23.
