Thank you for the info! I let my oldest daughter look at it and she says the tip of the battery still turns red so it couldn't be the battery, she thinks it's the Cartridges but we tried all 5 Cartridges and none worked!
TLDNR: MORE MECHANICS
There are 4 parts to an ecig: the power source, the switch, the atomizer, and the juice tank. In cigalikes the juice tank is usually the tip (in pods the atomizer and the tank are combined) the atomizer, or coil, is in the middle, and the battery, which combines the power source and the switch, is on the end. Sometimes, like in many disposables, the juice tank is a qqqqqqsatuqrated pith, like in a marker. The light going on (which is I think what your daughter is describing) indicates the power source and the switch are both functional, though the switch may be fouled, and not behaving normally. Autoswitches have a rep for fragility and are easy to foul. The switch allows power to the atomizer which heats and vaporizes the juice which the tank passes to the atomizer much like the power is passed to the atomizer. If any of these passings are broken the thing doesn’t work.
It’s a bit like a gas engine which needs fuel, spark, and compression. If the juice doesnt pass to the atomizer or the power doesn’t pass to the coil in the atomizer, or the coil in the atomizer is broken and can’t heat up you get a broken chain of behavior and the system fails. One or more (but probably only one) of these things isn’t happening. If it’s not the diaphragm auto switch (the most common failure point in cigalikes to the point that manual switches which are just buttons became popular) it’s something else. All a box mod is is a really fancy battery. That’s part of why it’s called a mod. It’s an ecig battery with additional features.
