The Krazy Bar 7500 covers the mid-range without much fuss. It's rated for up to 7,500 puffs, which for most people is a week or two, though that shifts with how often and how hard you vape. The 650 mAh battery recharges, so on a device holding this much e-liquid you're not stuck throwing it out early because the battery gave up first. There's a small LED screen for battery and usage, and it fires on the draw rather than a button. Krazy Bar uses a vertical coil here, which mostly helps keep the flavour and vapour consistent through the device rather than tailing off. Nicotine is 20 mg/mL salt for a smooth hit. It's a solid everyday disposable if you want decent length and a charge port without stepping up to the very large devices.
