I just bought a Joyetech eGo-C Twist 1000mAh battery from MVS, and after checking out I realize I failed to get a charger. I already own a Kanger EVOD2 starter kit, which comes with the EVOD battery and charger. Can I safely use this charger for the eGo-C Twist battery as well? It looks like the standard USB-style cable that screws on to the eGo battery, and that connects to a wall charger. (charger says 5V at .5A)
