Today only, Newegg offers the IOGear GearPower 11,000mAh Portable Battery, model no. GMP10K, bundled with a Macally Universal USB AC / Car Charger, model no. USBPOWER (it's added to your cart automatically), for $37.99. This $10 mail-in rebate drops it to $27.99. With free shipping, that's only $3 more than our mention from a month ago of the battery alone and the lowest total price we could find for these items purchased separately elsewhere by $26. It works with iPhones, iPods, iPads, and most devices which plug into a USB or microUSB power source.
