The Tornado Manual Passthrough is basically a 650 mAh Tornado battery with a mini USB-connection on the end. This allows plugging it into an external power source with the included USB-cable. The battery will be recharged every time it’s plugged in and you can vape while charging or use it like a regular battery. The Manual passthrough battery is compatible with all Tornado atomizers and cones but the cable cannot be used with a regular Tornado battery.

Personally, I am a big fan of this passthrough. First, it has a bit more life than a standard ego battery. Plus, it has the usb connection. I found that, over time, the chargers I have for the ego would get gunked up with residue from the occasonial spill, and become useless. With the pass through, you make the connection from the other end. Plus, you can plug it right into a PC and vape at the same time. If you’re an ego user, this is a must.
It is pricey though. And it doesn’t seem to matter where you go for it. It’s always substantially more expensive than a regular ego battery.
