Newegg offers the Thermaltake 7,000mAh LUXA2 P1 Pro Ultra Capacity External Battery Pack, model no. PO-UNP-PCP1SI-00, bundled with the Scosche Dual USB Home Charger, model no. GPSPWRR, for $34.49. (The charger is automatically added to cart.) This $20 mail-in rebate drops it to $14.99. With free shipping, that beats our May mention (when we saw the battery pack alone for pennies less), and is the lowest total price we could find for the power bank alone now by $23. It's compatible with most smartphones and tablets and features a rubber bumper, LED indicator, and built-in cord-keeper. Rebate expires July 30.
