Why is my Hayati Pro Max+ 4000 not working, and how do you fix it?

Most of the time, a vape that stops working has a simple cause: a low battery, a pod that isn't seated properly, a blocked airflow path or a pod that has run dry. Work through those in order and you'll usually find the problem in a few minutes. If none of them help, stop using it and contact the seller.

The Hayati Pro Max+ 4000 Prefilled Pod  has a battery screen, a Type C port and a draw activated pod system, so there are a few clear things to check. One note first. The listing has no manual or troubleshooting section, so the steps below are general advice for this style of device, not instructions from the maker.

What should you check first?

Start with the quick checks. They fix most problems.

•  Battery: look at the battery percentage screen and charge it if it's low 

•  Pod: make sure the pod is pushed fully into the device 

•  Airflow: check the air holes and mouthpiece for lint or dirt 

•  Draw: take a firm, steady puff, because the device fires when you draw on it 

•  Liquid: a pod that has run out of liquid will stop giving vapour

If one of these is the cause, the device should work again straight away.

Is the battery flat?

This is the most common reason. The listing says the device has an 850mAh rechargeable battery with Type C charging and a battery percentage screen. If the screen shows a very low number, or nothing at all, plug it in.

Give it a few minutes before you try again. A completely flat battery sometimes needs a short charge before it responds. The listing doesn't say how long a full charge takes or whether a cable is included, so keep a Type C cable of your own handy.

Anyone comparing battery sizes and charging across other devices can browse the range of rechargeable vapes to see how they differ.

What if it won't charge?

If the screen stays blank when you plug it in, try these in order:

•  Use a different Type C cable 

•  Try a different adapter or USB port 

•  Look inside the port for lint and clear it gently, without pushing anything sharp inside 

•  Charge on a flat surface at room temperature 

•  Leave it plugged in for a few minutes before you check again

If it still won't respond, the device may be faulty. Don't keep trying with damaged cables or forcing the plug in.

Is the pod seated properly?

A loose pod is a common cause of a device that won't fire. Take the pod out, check the connection points for dirt or damage, and push it back in until it sits firmly.

Make sure any protective seal or cap has been removed. Pods are often sealed in the packaging, and a forgotten seal can block the airflow.

The listing describes a 1.5ml pod plus a 5.5ml refill container, but it doesn't explain how the two work together. Don't open or refill anything unless the maker's instructions say how, and ask the seller if you're unsure.

Is the airflow blocked?

This device is draw activated, so it needs a good flow of air to switch on. Dust, lint or a drop of liquid in the air holes can stop it firing.

•  Check the air holes and the mouthpiece 

•  Wipe the outside gently with a dry cloth 

•  Take a steady draw, not a very light or very hard one 

•  Don't blow into the mouthpiece

Blowing into a vape can push liquid back into the device, so avoid it.

Has the pod run out of liquid?

If the device fires but you get little or no vapour, or the taste is harsh and burnt, the pod may be empty. A burnt taste is often a sign that the coil is dry.

That can happen when you take lots of puffs close together, so give the coil a few seconds between puffs. The listing says up to 4,000 plus puffs , which is an estimate. At around 200 puffs a day, that's roughly 20 days, so a device that's been used heavily for a few weeks may simply be finished.

Why does the vapour look weak or the taste flat?

Weak vapour usually means one of three things.

•  The battery is low, so the coil isn't heating properly 

•  The pod is nearly empty, so there's not enough liquid reaching the coil 

•  The airflow is partly blocked, so not enough air is passing through

Charge the device first, then check the pod and airflow. If it still tastes flat, the pod is probably at the end of its life.

Why is it leaking?

A little condensation around the mouthpiece is normal. A pod that's dripping or soaking the device isn't.

If it's leaking, stop using it, wipe off any liquid with a tissue and wash your hands. Keep it away from children and pets, and don't try to open it. Leaks can happen if a pod is damaged or hasn't been seated properly, and a leaking device should be replaced.

Could the weather be the problem?

Yes, sometimes. Very cold conditions can make the liquid thicker and the battery sluggish, and very hot conditions can affect the battery too. Leaving a device on a car dashboard is a bad idea.

If it's been somewhere very cold or hot, bring it back to room temperature before you try again.

When should you stop using it?

Some problems need you to stop straight away. Stop using the device and don't charge it if you notice:

•  It's getting very hot 

•  The body is swollen or bulging 

•  It smells of burning 

•  Liquid is leaking from the battery area

Put it down on a hard surface away from anything flammable. Don't try to open it, and contact the seller.

What are your options if it's faulty?

The listing offers a 30 day returns policy and a slip for exchanges. If your device is dead on arrival or stops working early, keep your order details and take clear photos or a short video of the problem.

Contact Vape Spot Wholesale with those details. Having your order number ready makes it quicker to sort out.

What UK rules should you check before buying?

GOV.UK guidance says nicotine e-liquids can be no stronger than 20mg/ml, nicotine vape tanks can hold no more than 2ml, and nicotine refill containers can hold no more than 10ml. Products also have to be notified to the MHRA before they can be sold.

Since the single use vape ban on 1 June 2025, a vape also needs a rechargeable battery, a refillable or replaceable pod, a replaceable coil where one is fitted, and refills that are available separately. A rechargeable battery on its own doesn't prove a device is compliant.

The listing's 20mg strength, 1.5ml pod and 5.5ml refill container sit within those limits. The page makes no claim about MHRA notification, so check the packaging and the MHRA list for the exact version you receive. If you'd like to compare liquid strengths across the wider range, you can browse the e-liquids at Vape Spot Wholesale.

What should you know about nicotine and health?

Nicotine is addictive, and vaping isn't without risk. The long term effects are still being studied. The listing says the product isn't suitable for non smokers, under 18s, or anyone pregnant or breastfeeding, and the site advises against use with cardiovascular disease or seizure disorders.

Some people notice a dry mouth, throat irritation, coughing, headaches or dizziness. If symptoms last, stop using the device and speak to a healthcare professional.

Getting your next order right

Once you've got your device working again, it's worth thinking about what to do differently next time, like keeping a spare cable and a spare device close by. Whether you're buying for yourself or keeping a shop's shelves stocked, planning your next order can save you a lot of hassle.

What is the difference between wholesale and retail?

Retail is when you buy one or two items from a shop at the normal shelf price. Wholesale is when you buy in bigger packs, usually boxes, straight from a supplier, so each item costs less. Shops buy this way so they can sell on to customers, and many everyday buyers use it too.

•  Retail: single items, normal shelf price, bought from a shop 

•  Wholesale: boxes or bulk packs, lower price per item, bought from a supplier

Why can buying wholesale work out better?

Buying wholesale can save you money and effort, as long as you'll really use what you buy. Here's why it often works out better:

•  Lower price per device: boxes usually cost less per item than buying one at a time 

•  Fewer orders: one box can cover weeks or months of use 

•  Steady supply for shops: shelves stay stocked without repeat trips 

•  Wider choice: more flavours and brands in one place 

•  Easy to start small: with no minimum order, you don't have to buy a huge amount

Retail still makes sense if you only want to try one flavour. Wholesale tends to win once you know what you like, or when you're stocking a shop.
