I still enjoy using fire to heat my Vapcaps whether it be a jet flame, soft flame or a lazy dazy candle when soaking in the tub. Nothing to plug in or charge has its benefits. Mostly I use the aomia flint jet lighters. They're tiny and compliment the shape and size of the Vapcap. I like that they are cheap and dependable.
Lighters for our DV stuff? Yeah, we've got a few, soft flame Bic (regular and candle length) and Djeep and torch Vertigo triples and a Blazer Firefox.
We've got a couple Fluxer IH options, too. I like the variety.
