Each device comes pre-filled with 1.3ml of vape juice, which will provide users with between 200 and 300 puffs of vapor, and they will be sure to satisfy your cravings because Puff Bars are filled with 5.0% (or 50mg) strength nicotine salt ejuice. There now also avaliable in 2.0% (or 20mg) nicotine strength versions.
You can't get a vape that's much simpler to use than the Puff Bar. It has no buttons, you just inhale to activate the device. You also don't need to worry about refilling it, recharging it, or finding replaceable pods. When it runs out of ejuice you just throw it away and get a new one, that's the beauty of disposable vapes.
