Single Battery Mods use just 1 x 18650 or 26650 battery. They are perfect for Vapers who prefer a smaller and more compact Mod.
We do not recommend using the built-in USB charging feature on mods that use replaceable lithium ion cells. Lithium ion batteries must be balance charged using an external charger to avoid damaging the cells and reduce the risk of venting. Micro and mini USB ports are fragile and as such we do not offer a warranty or repair service on any USB charging ports if you choose to ignore this warning.
