The new iPad has a 11,666 mAh battery, 70% larger than iPad 2, but the Retina Display and 4G LTE will cost more power, so, you must prepare an portable USB battery charger before a trip.
Energize your digital life with four times the portable power: the ZAGGsparq 2.0 is the standard for on-the-go charging. Convenient for travelers and business people, it carries four complete recharges for most power-hungry smart phones. The ZAGGsparq 2.0 recharges with a standard outlet and provides two USB ports for powering mobile devices. Perfect for everything from cell phones to hand-held gaming systems. Dead batteries and expensive spares are a thing of the past.
ZAGGsparq 2.0 has been specifically engineered to charge Apple’s iPad. It adds an additional 5 to 6 hours of video playback to the iPad. It will take the iPad from 0% to 60% and at the same rate the iPad wall charger charges the iPad.
