Sour Apple Ice RAZ LTX 25k

Runtime against size. The LTX 25K holds 16 mL of 5% nicotine on an 800mAh battery and is rated for 25,000 puffs. The TN9000 is the smaller device at 12 mL and 9,000 puffs, but it adds adjustable airflow the LTX does not have. The LTX lasts far longer; the TN9000 lets you tune the draw.

Each RAZ LTX 25K comes pre-filled with 16 mL of e-liquid at 5% salt nicotine, and it is not refillable. When the e-liquid is gone the device is finished. It is intended for adults 21 and over who already vape or smoke.

The RAZ LTX 25K recharges over USB-C. It runs a 800mAh battery. Plug it in when the vapor starts to thin, which usually means the battery rather than the e-liquid. A full charge takes well under an hour and the device keeps its e-liquid throughout.

The RAZ LTX 25K has a smart display, so both levels are readable at a glance rather than guessed. Flavor fading and a faint burnt taste mean the e-liquid is genuinely finished. A blinking light on its own usually just means it needs charging.

At a typical 400 to 650 puffs a day, 25,000 puffs works out to about 5 weeks to 2 months. Heavy all-day vaping brings that down considerably, and lighter use stretches it well beyond.
