If the USB works off the power of the computer to fuel the EM901 battery, why do you need a rechargeable battery too?
Thank you!
Thank you!

Thanks for that! I don't know what a vapor king is since there are no pics! I think I have a vapor viper (em901?) and it is for that....
But then again, what is this??????:
USB Manual Switch - Eastmall International Co.,Ltd
Is there a US supplier that has the battery pack USB passthroughs?
