    I asked KC from the Dania Beach store if it would be OK to charge a phone via the USB port and he thought that would be fine. Anyone done this before? I mean USB power should be USB power (the memory stick needs power too.)

    I was told by a knowledgeable store rep that the USB ports would charge even high-power devices like iPads.

    USB ports charge at 500 mA (milliamps) such as PCs, the USB port on the car, your standard USB port that goes to a wall charger can put out 1000 mA. 500 mA will NOT keep a high powered device that has wifi up and a large LCD running. Its a net loss. (by the way I test that stuff )

    There are a couple of 'standards' for 2A USB charging. I have two such devices (and I imagine the iPod also wants 2A ideally). The two devices I have are compatible with each other's chargers, but I think Apple went and did their own thing (I will not vouch for that).

    My Galaxy Nexus will maintain (and slightly increase) charge when plugged in to a 1A car 12V USB converter when navigating.

    I wouldn't do it unless you have what the tesla rep said in writing.

    It specifically says in the manual: (From page 7-6 in the roadster 2.0 manual)

    I knew about the comment in the manual, but when the Ranger said it was OK to use, I figured I'd ask the forum. Seems like no-one is actually using it to charge anything - at least the're not confessing to it ;-)

    That is pretty ambiguous. It could mean that there is no connectivity to the display from the personal device. I've found that, as an example, Apple computers' USB port will charge an iPhone just fine, but most other makers won't. There is a difference in the amount of power different manufacturers can give to the USB port.

    At the risk of repeating myself, I asked explicitly about the power output of the USB, and I was told that it would be enough to keep up with an iPad in full operation.

    This is a Roadster thread. Assume you asked about Model S?

    I agree, especially considering the 12VDC socket issue here:
    WARNING: Do not plug an AC inverter into your 12VDC socket!!

    Err, sorry, yes. I read posts using the "New Posts", not going to particular forums. So often I don't note the forum. Sorry!
