Ending today, Newegg offers the RAVPower Dynamo-On-the-Go 10,000mAh External Battery Pack in Black, model no. RP-PB04, for $13.99 with free shipping. That's the lowest total price we could find by $6 and the best no-rebate price we've seen. (We saw it for $2 less after a rebate three weeks ago.) It features an LED status bar, dual USB outputs, and includes four connectors.
