All current stock of Powertraveller products is compatible with the Apple iPad.
Please be aware that the iPad will only "power" or "run" from the Powertraveller charger and the iPad screen will display a "not charging" message. If the iPad is locked and not being used, the battery charge level will actually increase by approximately 1% every 10 minutes.
The reason the products are not currently able to charge the iPad is due to the iPad's requirement for a 2.1amp charge. The max output of our products have is up to 1amp and this is the same for all 3rd party charging accessory manufacturers.
Powertraveller is working hard to find an alternative way for our products to charge the iPad and we'll keep you posted!
