Newegg Flash offers the RAVPower 14,000mAh External Backup Battery Pack in Black or White for $34.99 with free shipping. That's the lowest total price we could find by $5, although we saw it with a car charger for the same price two weeks ago. The battery pack features a built-in flashlight, auto-off, and compatibility with a wide range of devices (including the iPad, iPhone, and Android phones and tablets). Deal ends March 3.
