How to use a RAZ RX for the first time

1. Unbox it. Take the device out of the box and remove any cap, sticker or seal on the mouthpiece.
2. Wake the screen. A short draw wakes the 3D HD display. If the battery reading looks low, charge it before you keep going.
3. Start in Normal mode. The screen shows NORM, BOOST or SUPER. Stay in Normal for the first session unless you already know you want a higher-power mode.
4. Take a slow draw. The RAZ RX is draw-activated. There is no fire button. Steady two- to three-second draws work better than short, hard pulls.

New to disposables in general? Our how to use a disposable vape guide covers the basics that apply across brands. If you have a RAZ LTX or a RAZ Vue instead, use how to use a RAZ LTX or how to use a RAZ Vue — those models are set up differently.

RAZ RX Normal, Boost and Super Boost

Our product page lists three modes and their puff ratings:

• Normal: rated for up to 50,000 puffs. This is the default mode and the highest listed rating.
• Boost: rated for up to 25,000 puffs. Higher power, so the listed puff count is lower.
• Super Boost: rated for up to 20,000 puffs. The highest-power setting, and the one that uses e-liquid and battery the fastest.

The product page puts it directly: higher power means fewer puffs. The screen shows NORM, BOOST or SUPER so you can see the active mode. The switch method can vary by batch, so use the leaflet in the box and then confirm the new label on the screen. Real puff counts depend on draw length, mode and charging habits. Brand-level ratings for every RAZ we stock are on how many puffs a RAZ vape has.

The RX also has adjustable airflow. Use the airflow control on the device to make the draw tighter or more open. For a general walkthrough of that feature, see adjustable airflow vapes.

How to charge a RAZ RX

The 800 mAh battery charges through USB-C. A 50K rating is a large puff figure for one battery, so expect to recharge it many times over the life of the device. Use a standard USB-C cable and a low-power adapter or computer port, watch the battery reading on the display and unplug once it shows full. Avoid high-output chargers and leaving it plugged in after it reads full.

Charge it when the battery reads low rather than running it all the way down. Recharging will not bring the device back once the e-liquid is gone. For general charging tips, read how to charge a vape. For battery life between charges, see how long a vape battery lasts.

What to do if your RAZ RX will not hit

1. Check the battery. If the screen shows low or no battery, charge it for a while and try again.
2. Check for remaining e-liquid. If the device is empty, recharging will not help. It is time to replace it.
3. Clear the airflow. Make sure no cap, wrap or pocket lint is blocking the mouthpiece or the air intake. Confirm the adjustable airflow is not closed all the way.
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. For a RAZ-specific checklist, use RAZ vape not hitting: battery, airflow, sensor and reset checks or RAZ vape not working.

When to replace your RAZ RX

The RAZ RX is sealed and pre-filled, so it cannot be refilled and the flavor cannot be changed. Replace it when hits stay weak or taste burnt even after a full charge, or when you can tell the e-liquid is gone. A burnt taste usually means the wick has run dry.

RAZ RX FAQ

How do I take my first draw on a RAZ RX?

Remove all packaging and any mouthpiece seal, wake the 3D HD screen with a short puff, and draw gently from the mouthpiece. The RAZ RX is draw-activated, so there is no button to press to produce vapor.

What do Normal, Boost and Super Boost mean on the RAZ RX?

They are the three power modes on our product page. Normal is rated for up to 50,000 puffs, Boost for up to 25,000 and Super Boost for up to 20,000. The screen shows NORM, BOOST or SUPER. The switch method can vary by batch, so use the leaflet in the box.

How do I charge a RAZ RX?

Use a USB-C cable and a standard low-power USB port or wall adapter. The 800 mAh battery’s level appears on the display. Unplug once it reads full. Recharging will not refill the e-liquid.

Why is my RAZ RX not hitting?

The most common causes are a low battery, an empty device, a blocked or fully closed airflow path or short, hard puffs. Charge it, check that e-liquid remains, open the airflow and take slower, steadier draws. A reset is the next step if those checks do not help.

When should I replace my RAZ RX?

Replace it when hits stay weak or burnt after a full charge, or when the e-liquid is gone. The RAZ RX is sealed and pre-filled, so it cannot be refilled.
