The Puremax Q looks simple and pocket-size, but it hides strong power. Inside is the YiHi SX255J chip and a 1500mAh battery. Let’s see how to use it in daily life. 01｜First Fill: Use the Airplane Mode Puremax Q has a special trick — the rotating mouthpiece, also called airplane mode. • Travel or storage: turn it counter-clockwise to close juice flow (airplane mode on). No leaking. • Ready to vape: turn it clockwise to open (airplane mode off). First time filling: slide open the fill door, fill the tank full, close the door, and wait 3–5 minutes. The cotton needs to be wet before vaping. 02｜Two Ways to Vape Everyone has a different habit. Puremax Q gives you two choices: • Auto Draw: just inhale, no button needed. • Dual Mode: inhale or press the button, both work. Press the fire button 3 times quickly to change the mode. 03｜Smart Vibration Alerts Puremax Q talks to you with small vibrations: • Low e-liquid: short vibration, time to refill. • Empty tank: long vibration, device stops to protect the coil. • New pod too dry: short vibration when cotton is not ready. No more dry hits. 04｜Which Mouthpiece Fits You? In the box you get two drip tips: • Wide driptip → for bigger clouds, RDL/DL style. • Narrow driptip → for MTL, stronger throat hit, good with higher resistance. It also supports most 510 drip tips. If you use your own, remember to control the juice flow with airplane mode. 05｜Daily Care Tips • Clean the condensation with a cotton swab. • Not using for long? Turn on airplane mode. • Charge with Type-C, 5V/1A. Don’t use fast chargers. 06｜Why People Like Puremax Q • Airplane mode: leak-proof design for travel and storage. • Flexible use: auto or button, your choice. • Smart protection: always takes care of the coil. • Custom style: change drip tips if you like. Final Words Puremax Q is more than just a small pod. It’s easy, smart, and safe. Great for new users, but also fun for advanced vapers. Put it in your pocket, and enjoy a smooth vape anytime.
