- Butane Lighter - Not Holding a Flame?
You might just add to make sure any ventilation holes around don't have lint blocking that would impede the designed air mixture. It could be that some debris has gotten into the valve and is restricting it from inside. Maybe has gotten in when refilling.
- What is the yellow ball/orange ball on the wire of my butane lighter?
That ball is made to change the colour of the flame, it's kinda cool how it changes, it changes because there's layers of metals in that ball, kinda like a giant jawbreaker, that burn away gradually.
- How do i charge the electric for my butane lighter?
It may need a watch-size battery, or it is a quartz piezo ignition. If quartz piezo, you may have to toss it and get a new one. If it is a lighter that is high cost or high sentimental value, look for a shop that repairs watches and call them to see if they can fix it or recommend a place that does.
