Can I chargue my cellphone with that?



Yes, it is a useless feature in AF firmware. You have to have one of those 510-to-USB adapters in order to use it.

Many have complained about the feature to AF on the AF forum, stating that it should be removed and replaced with something more useful. But AF thinks it is a good feature to have for some reason and refuses to remove it.
