How do I charge the AirStash battery?
The built-in lithium-polymer battery in the AirStash charges when you plug it into a computer. Simply plug the AirStash into a free port on your computer or a powered USB hub (built in to many LCD monitors) to charge the AirStash and drag files to your SD/SDHC card. You can use the included USB extension cable if you’re unable to plug the AirStash in directly.
