Yes it is a 510 thread, your charger won't be rated in mah, but if you mean the charger you use for the 650mah batteries then yes you can use it, (it's rated at 420mA)
But I would think the
USB Pass-through Battery would be a better option, as it uses the latest eGo battery tech, and give you charge remaining indication, short protection, and if the worst should happen you you run completely out of battery power, you can hook it up to a usb supply and vape while it's charging
