This is a new and improved version with a much better strain relief design where the cable enters the tube.

This is THE BEST automatic passthrough we have ever tested! The switch is super reliable and not triggered by a microphone switch like many others. The cut off time is about 5-6 second but because it runs at 5 volts it gives you a stronger hit than a normal e-Cigarette battery. This is fully compatible with your KR808D-1 e-Cigarette cartomizers AND your SLB DSE901 Mini e-Cigarette atomizers. We don't recommend this for DSE901 drip smokers because it is an open connector design and liquid leakage is possible even though DSE901 atomizers rarely leak.

If you spend any time near a computer or other USB power source then this is a MUST HAVE for your e-Cigarette shopping list! You can plug it into your iPhone charger and vape all day without the worry of using your e-Cigarette batteries. Save them for when you aren't near an alternative power source.
