This is the only cordless lap desk that recharges an iPad and iPhone simultaneously. A built-in 10,000 mAh rechargeable battery charges an iPhone up to six times, an iPad for 10 hours, or provides supplemental power to any USB-powered device without requiring connection to a wall outlet. The lap desk’s sturdy legs adjust to three different heights and the surface tilts to nine different angles, allowing you to position devices at a preferred, comfortable angle. Two USB ports on the lap desk surface make it easy to charge devices or power the included gooseneck LED lamp that generates bright yet focused light to illuminate screens without disturbing a sleeping partner. The lap desk folds to the size of a laptop computer for ease of storage or travel and its battery recharges in 24 hours via the included USB cable. 22" W x 12 1/2" D x 11" H. (4 3/4 lbs.)
