DIY USB passthough Issues

[tdn90]

So, I have 2 e-cigs…

Lets call them, E-cig A, and E-cig B.

E cig A has a Female battery, Male Atomizer, and Male USB charger.

E cig B is the opposite, Male Bat, Female atty, and USB Charger.

So theoretically, I can plug The Atomizer from E cig A, into the Charger for e-cib B, and have a USB passthrough… However, In practice, once plugged in, the USB charger supplies constant power to the Atty, hence it stays lit! Anyone know how I can add a manual switch to the device, or keep the atty from burning out!?!?



ecig A atty (+ cart and mouthpeice), and ecig B charger:

PS. E cig A is a 084 knockoff from ebay.co.uk for $25 shipped.
E cig B is a Health E -Cigarette, form ebay.co.uk for $30 shipped.

Just wire in a momentary tactile switch. You MIGHT be able to do this by just cutting into the USB cable/charger, finding either the positive or negative lead and soldering in the switch, but it might be a little cumbersome/less practical than building one from scratch.
BTW, are you using a 510 w/a M401 charger?
