I have a Garmin Forerunner 301 and it's missing the AC adapter so I cannot charge it but it does have a usb port. What I don't understand is why I need an AC adapter to charge it when a computer can do the same thing because both have a usb support system. Can someone explain to me why this may be the case?
The port on the device is a 5 pin mini B
Thanks
