to charge a phone its better to use a charger usb that connects to the lighter dock.Hello, I have a 500 sport, I have been trying to charge my phone using the usb port, it charges so slowly its not even worth it, not even 8% after a 50 min drive. Is there a way to fix this?
On the 500 I think the port is only meant for connecting and not delivering the high current needed by smart phones. A normal USB port is half an amp but most phones need 1.2 amps and bigger more power hungry devices can need as much as 2.4 Amps, in this instance it's not surprising it takes a long time to charge a phone
Try B&M - my iLuv twin USB was 4 quid and can run/charge my Garmin and charge an iPad at the same time with no issues
What is needed is something like this.
They are available with different outputs, but generally at least 1A is needed for modern smartphones. Must be able to find something like this locally.
