How to use a RAZ LTX for the first time

1. Unbox it. Remove the box, plastic wrap and any silicone cap or seal on the mouthpiece.
2. Check the screen. The Mega HD display shows battery, e-liquid, wattage and mode. If the battery reads low, charge it before your first session.
3. Take a slow draw. The RAZ LTX is draw-activated, so just inhale gently from the mouthpiece. There is no fire button.
4. Pace your puffs. Slow two to three second draws give the coil time to heat and give you a fuller, smoother hit than short, hard pulls.

RAZ LTX Normal and Boost modes

The RAZ LTX has two power modes, and the display always shows which one is active:

• Normal (12 W): rated for up to 25,000 puffs. Best for all-day use and getting the most out of the device.
• Boost (24 W): rated for up to 15,000 puffs. A warmer, stronger hit that uses e-liquid and battery faster.

Use the mode control described on your device packaging to switch, then confirm the new wattage on the screen. Real puff counts depend on puff length, mode and charging habits.

How to charge a RAZ LTX

The RAZ LTX charges through USB-C. Plug it into a laptop port or a low-power wall adapter, watch the battery reading on the display and unplug once it shows full. Avoid fast-charge bricks and leaving it plugged in overnight. For general charging tips, read how to charge a vape.

Charge it when the battery reads low rather than running it fully flat. A weak battery is one of the most common reasons a RAZ LTX feels like it is hitting softer.

What to do if your RAZ LTX won’t hit

1. Check the battery. If the screen shows low or no battery, charge it for a while and try again.
2. Check the e-liquid reading. If it shows empty, the device is done and needs replacing.
3. Clear the airflow. Make sure no cap, wrap or pocket lint is blocking the mouthpiece or the air intake.
4. Change your draw. Take slower, steadier puffs. Very hard pulls can pull e-liquid into the mouthpiece and cause gurgling.
5. Try a reset. Follow our how to reset a RAZ vape steps.

If the screen lights up but you get no vapor, see why is my vape lighting up but not hitting. Using a RAZ Vue pod system instead? It works differently, so go to RAZ Vue not working.

When to replace your RAZ LTX

The RAZ LTX is sealed and pre-filled, so it cannot be refilled. Replace it when the e-liquid reading is empty, or when hits stay weak or taste burnt even after a full charge. That burnt taste usually means the wick has run dry.
