Step-by-Step Guide: How to Use the Hayati Pro Ultra 15000
Step 1 — Unboxing & Preparation
Inside a typical Hayati Pro Ultra 15000 box, you’ll find:
-
1 × Hayati Pro Ultra 15000 device
-
Pre-installed dual e-liquid tanks
-
Protective mouthpiece cover (sometimes included)
-
User instructions card
Before Your First Use:
-
Remove all packaging, foil, and shrink wrap.
-
Take off any silicone bung or plastic mouthpiece cap.
-
Peel away any airflow stickers or protective labels.
-
Inspect the device for cracks or visible leaks.
-
Identify the flavour switch mechanism near the mouthpiece.
Once unboxed, you’re ready to charge the device.
Step 2 — Charging the Device
The Hayati Pro Ultra 15000 includes a rechargeable internal battery, typically quoted around 550mAh. This allows you to use the entire 24ml of liquid without the battery dying prematurely.
How to Charge It Properly
-
Locate the side USB charging port (USB-C or micro-USB depending on the version).
-
Connect a high-quality USB cable to a reliable wall adapter (1A–2A).
-
The visual display screen will show a charging icon or animation.
-
Leave it to charge until the indicator shows full battery.
Charging Safety Tips
-
Charge on a flat, hard surface
-
Avoid charging on beds, blankets, or upholstery
-
Do not use frayed or cheap cables
-
Unplug the device once fully charged
-
Allow the device to cool if it gets warm
A fully charged battery ensures stronger vapour and better flavour consistency.
Step 3 — Inserting the Pod (Important Clarification)
Unlike pod systems, the Hayati Pro Ultra 15000 does NOT use removable pods.
-
The dual tanks and mesh coil are built into the device
-
There is no pod installation, no refilling, and no coil changes
The “pod” is already installed directly from the factory. This makes the device:
-
Simpler
-
Cleaner
-
Leak-resistant
-
Beginner-friendly
Step 4 — Switching Flavours (Dual 12ml Tanks)
One of the biggest advantages of the Hayati Pro Ultra 15000 is its dual-tank flavour system.
How the Dual-Tank System Works
-
Tank A = Flavour 1 (12ml)
-
Tank B = Flavour 2 (12ml)
-
Both tanks are accessed by a flavour-switching mouthpiece or twist selector
-
The display may show which tank is active
How to Switch Flavours
-
Rotate or flip the mouthpiece based on the labelled direction.
-
The device automatically switches to the other tank.
-
Take 3–5 gentle puffs to allow the flavour transition.
-
Enjoy your new flavour instantly.
Why There Might Be Slight Flavour Mixing
-
The coil shares the initial airflow chamber
-
A tiny amount of crossover is normal
-
It clears after a few slow puffs
Dual-flavour capability is ideal for vapers who get flavour fatigue or enjoy rotating profiles.
Step 5 — Start Vaping (Correct Technique)
The Hayati Pro Ultra 15000 is draw-activated, meaning:
-
No power button
-
No settings
-
No menus
Simply inhale to activate the mesh coil.
How to Vape Correctly
-
Place the mouthpiece gently in your mouth.
-
Take a slow, smooth MTL (mouth-to-lung) puff.
-
Avoid hard or aggressive pulls, which can:
-
Flood the coil
-
Cause gurgling
-
Reduce vapour
-
-
Leave 2–4 seconds between puffs to let the wick re-saturate.
The 1.1Ω mesh coil is designed for clean flavour, stable throat hit, and consistent nicotine absorption.
Step 6 — When & How to Replace Pods (Device Replacement)
This device uses a sealed dual-tank system, which means:
-
You cannot replace pods
-
You cannot refill the tanks
-
You cannot change coils
When the tanks are empty, you replace the entire device.
