The eGo passthrough: has a 5click on/off button, which can be used to prevent unwanted activation when the device is not in use.
When in the on position, you just push the button which will light up blue.
Charging the eGo passthrough: takes about 3 hours, and can be charged in either of 2 ways,
1: Through a USB connection
Simply unscrew the end cap and attach the USB cable, to use it as a pass through.
When you click 5 times to switch it off it stops unwanted activation, though, you could still use it whilst sitting in front of the computer, whilst it is charging.
2: Through a 510 connection, though not recommended
When used as a battery, you can click 5 times to switch it off to stop unwanted activation.
We recommend you only charge with the cable provided and not through the 510 connection!
