So I've just bought this - Amazon.com: Anker® Astro3 10000mAh Dual 2A USB Output External Battery Backup and Charger for iPhone 4S / 4 / 3GS, iPod, iPad, iPad 2, the New iPad (iPad 3); Most Android Phones (Samsung Galaxy S / S2 / S3, HTC One X One S Sensation EVO, Motorola Dro
It's an external USB battery charger to charge my eGo's when I go camping next month. It arrived today and it's now fully charged and ready to be tested. However, it has a little switch on the side saying 9v and 12v, which one do I switch it to to charge my eGo or doesn't it matter?
I've quickly tested both and the charging light comes on on my eGo USB charger when I plug it in to the external battery so they both seem to work, however, I don't want to brake anything and need to know whether it's 9v or 12v I should switch it to?
The output of both USB's on it are 5v.
Thanks.
