As one of its daily deals, A4C offers the Motorola 3,000mAh Portable USB Power Pack Battery Charger in Black or White, model no. P3000, for $7.95 with free shipping. That's a buck under our January mention and the lowest total price we've seen. (It's a current price low by $7, although MobilePros via eBay charges a buck more.) It features a USB charging port and built-in microUSB cable. Deal ends today.
