ThanksI wouldn't recommend using the USB port to charge the batteries inside the , for reasons that has been well discussed in other threads. A $35-$50 smart charger is pretty cheap insurance for $400-$600 radio.
Thanks for all the help.You dont have to use the cord that came with it. I have a couple longer generic usb cords that work fine. Its only supplying power. If you use another cord when programming the scanner there possible could be some problem with corrupt data. Doubt it but possible.
You can use a usb extension cable. Or a phone charger. To power it no problems.
