I currently use a vape mod with liquids at 6mg nicotine. I'm fed up with liquids and leaking tanks so I ordered a vype pebble and 2 packs of 6mg cartridges. The website claims all day battery but I only get about 3 hours before I have to recharge. I have no idea what the battery is rated at as this information is not stated anywhere on the site. Secondly 6mg cartridges have no taste and you don't feel the hit. You need at least 18 which I don't understand as I've always used 6 mg or less. Probably alright for a night out but you'd want a spare battery with you.
