I know I can't use the AC charger for a regular 510, but I use the USB portion (that fits in the AC charger) in my car for my ego battery and I was wondering if I could charge a regular 510 battery in it. On the USB portion of the charger it says "ego usb charger input DC 5V 500mA Otuput DC4.2 420mA"
thanks in advance!
