I've seen these things popping up on ebay for a while, and when someone mentioned them in the comments for another video I thought I'd get one and take a look at it.
They're basically a USB chargeable device about the same size as a normal lighter. When you press and slide the central button in one direction the USB charging plug slides out. When you slide it in the other direction a ceramic plate with a spiral heating element slides out and when pressed forward it starts to glow to light your cigarette.
The circuitry inside is very similar to that of an electronic cigarette. It has a six pin xm7100 control chip with some support components, a lithium cell and the heater assembly.

    I figured one of these had to last me 16 months to break even vs. the cost of just getting 8 or 9 Bic brand lighters, but after 1 month, the heating coil separated after only about 300 cycles. too tiny for me to solder or it'd last a couple more mos.

    Can anyone tell me if these can light pipes to or not I've seen the ones with arcs and the coils but I'm actually looking at this specific model at the moment and am not sure if the coils can do so

    Best thing about these are that no butane or any oils are needed

    You are supposed to wait till it starts flashing after you have lit your smoke otherwise the element is full heat and will melt the casing

    i recently got one of these for ยฃ1.69 off ebay …..its marvelous …..until the element broke (i smoke roll-ups and was very gentle) it lasted 3 days :-(………
    i then took it apart and then tried to see if the elements were for sale seperately on ebay…..no joy……
    mine is slightly different to yours and the element is soldered ,so i'm gonna try make a small wire coil to replace it.
    if successful i'll upload it.
