How To Refill Hayati Pro Ultra
How to Refill
the Pro Ultra
Yes you can. The post-ban Hayati Pro Ultra is a refillable rechargeable pod kit built for the UK market after the June 2025 ban. Here is the step-by-step refill process plus what e-liquid works best.
Yes. The post-ban Hayati Pro Ultra is designed as a refillable rechargeable pod system. It uses a 2ml UK-compliant pod that accepts any TPD-compliant 10ml nic salt at 20mg per ml or below. Pop the pod out, lift the silicone fill-port stopper, squeeze e-liquid to the max line, seal, reinsert and wait two minutes before your first draw. Pods typically last three to four refills before replacement.
What the spec sheet
actually tells you
Three practical figures every Pro Ultra user should know about the device, the pod plus the refill cycle.
UK compliant
The Hayati Pro Ultra uses a 2ml refillable pod which sits within the UK TPD legal limit for a single pod.
Five refills
One 10ml nic salt bottle refills the Pro Ultra pod five times delivering around 3000 total puffs.
Post-ban ready
Rechargeable via USB-C which keeps the Pro Ultra fully legal under the June 2025 single-use ban.
The Pro Ultra refill process takes about thirty seconds
Yes, the Hayati Pro Ultra is designed to be refilled. The post-ban version is a rechargeable refillable pod kit built specifically for the UK market after the single-use disposable ban came into force on 1 June 2025. It clears both the rechargeable and refillable legal tests required by the new rules. Here is the step-by-step refill process plus how to get the most out of each pod.
What the Pro Ultra actually is now
Hayati originally rose to popularity in the UK disposable era with the single-use Pro Ultra device. When the ban came into force the entire category had to pivot. The current post-ban Hayati Pro Ultra is a compact rechargeable pod system that uses a replaceable 2ml refillable pod. The main device houses a built-in rechargeable battery charged via USB-C. The pod unplugs cleanly from the device for refilling. A silicone fill-port stopper on the side of the pod seals the refill hole between uses.
The device carries MHRA notification plus full TPD 2016 compliance, meaning you can buy it legally from any UK-registered retailer. The flavour catalogue from the original disposable range has been preserved across the compliant pod format.
How to refill the Pro Ultra step by step
The refill process takes about thirty seconds once you know the sequence.
- Remove the pod from the device by pulling it straight up until it comes free.
- Lift the silicone fill-port stopper on the side of the pod. It hinges open without coming fully detached.
- Insert the bottle nozzle at a slight angle to avoid trapping air bubbles. The angle keeps bubbles out of the pod chamber.
- Squeeze slowly until the pod reaches the max fill line printed on the side. Do not overfill past the line.
- Close the silicone stopper firmly to seal the fill port.
- Wipe any excess liquid from the outside of the pod with a dry tissue.
- Click the pod back into the device until it seats with a definite click.
- Rest for two minutes before the first draw so the coil can fully absorb fresh liquid. Skipping this step produces a burnt first puff.
What e-liquid to use
The Pro Ultra is tuned for nic salt e-liquid in the 50/50 to 60/40 PG/VG range. Any UK TPD-compliant 10ml nic salt bottle at 20mg per ml or below will work correctly. High-VG shortfills designed for sub-ohm mod tanks are not suitable. The pod will not draw properly on thick high-VG liquid and the coil can flood.
Match your nicotine strength to your habit. Heavy smokers switching from 20 a day should start at 20mg nic salt. Lighter smokers start at 10mg. Ex-smokers stepping down from higher strengths work through 10mg, 5mg and 3mg in stages. Our pod vape kits collection stocks the Pro Ultra alongside every TPD-compliant nic salt strength.
When to replace the pod
A well-maintained Pro Ultra pod typically holds up for three to four full refills before performance starts to drop off. Three signals indicate it is time for a fresh pod. Flavour gets flatter refill on refill. Vapour production reduces at the same draw length. A slight burnt edge creeps into the taste even after a two-minute rest. When any two of these three appear together, swap in a fresh pod. The device itself stays the same.
This is the structural benefit of the post-ban pod format over the original Pro Ultra disposable. Before the ban when the device was spent it went in the bin. Now only a 2ml pod is replaced every few weeks while the device plus battery carry on for months or years of daily use.
Charging the device
The Pro Ultra charges via USB-C using the cable supplied in the box. Connect to a standard 5V 1A mains adapter or a laptop USB port. A full charge from empty takes approximately one hour. Avoid fast-charge phone adapters designed for high output which can shorten battery lifespan over time. The LED indicator on the device lights up during charging plus turns off or changes colour when the battery is full.
From empty pod to
first fresh draw
The refill process takes about thirty seconds once you know the sequence. Here are the four stages broken out clearly.
Pop the pod
Pull the pod straight up to release it from the device body. Lift the silicone fill-port stopper on the side.
Fill slowly
Insert the nic salt bottle nozzle at a slight angle. Squeeze gently until the pod reaches the max line printed on the pod.
Seal and wipe
Close the silicone stopper firmly. Wipe any excess liquid from the outside of the pod with a dry tissue.
Rest and vape
Click the pod back into the device. Wait two minutes so the coil can absorb fresh liquid. First draws should be short and gentle.
What to do and
what to avoid
Use 10ml nic salts only
TPD-compliant 10ml nic salt bottles at 20mg per ml or below. High-VG shortfills flood the coil and do not draw properly.
Charge before first use
The Pro Ultra arrives partially charged. A full USB-C charge cycle before first use gives the best performance and longest cell life.
Never fill past the max line
Overfilling causes leaks, fills the airflow channel and can damage the pod seal. Stop at the fill line marked on the side of the pod.
Replace the pod, keep the device
Pods last around three to four refills before flavour drops. Swap in a fresh pod. The device itself can last for months or years.
