![]() ![]() Some devices will charge with max current right off the bat, a few will be limited to initial max current, and a couple might not charge at all. The final point is that this really just varies on a device to device basis. The only device I can think of off the top of my head that won't charge at all without this enumeration is a Sony PlayStation 3 controller (but I'm sure there are more). But, this is only really an inconvenience, and most devices will charge with at least some initial current. The only thing to really consider is similar to what you mentioned in your question some devices will begin to charge at say, half of their current capacity, and only ramp up to full current once they've received some data from the charger/host device. ![]() I wouldn't worry about a device overdraw the current control is generally built into the device rather than the charger. Many, if not most devices will charge as soon as there is a voltage applied to their USB port, so I'd say that aspect of your setup is also good. For most ATX PSUs, the +5v rail has the largest current capacity of all rails on the supply. Compatible with all the latest cars which require a direct CAN connection. Features: USB connector plugs into most modern laptops (USB 1.1 or 2.0) A Serial Port version was also available click here for full specs.
