The Gcore Indicator 7000 keeps a slim, pocketable shape while still reaching around 7,000 puffs. That's a reasonable stretch for most people, with the usual caveat that longer or more frequent draws bring it down. The name points to its main feature: two separate indicators, one for e-liquid level and one for battery, so you can see exactly where each stands instead of being caught out when it runs low. It's rechargeable, worth having on a device this size. The 2 mL pod holds the flavour, and being able to top up the battery means you actually finish that juice rather than tossing it half full. Nicotine is 20 mg/mL salt for a smooth draw. If you want something thin and easy to carry that still lasts, this fits the brief.
