Hayati Pro Max Plus 4K

The Hayati Pro Max Plus 4K uses the same rechargeable Pro Max+ device as the 6K. Hayati call it the Pro Max+ 4000 Puffs, and each pack gives up to 4,000 puffs of 20mg nic salt. It comes in 30 flavours, most of them names you will know from the original Hayati Pro Max.

Hayati pitch the 4K as the lighter option. Its lower entry price makes it easier to try more flavours.

Vaping Products Duty started on 1 October 2026 at £2.20 per 10ml of e-liquid. A 4K pack holds 7ml against 12ml in a 6000 pack, so it carries less duty.

For a prefilled pod kit with nothing to fill by hand, this is the lighter way into the Pro Max+.

Hayati Fresh Tech

Every 4K pod arrives unactivated, with the e-liquid sealed away from the coil until you first use it. Hayati call this Fresh Tech. Because the pod only activates when you start vaping, Hayati say each new pack starts with fresh flavour.

Hayati 4K vs 6K: Which Size?

Both kits use the same Pro Max+ device, so the pods swap between them. A 6000 pack fits the 4K kit, and a 4K pack fits the 6000 kit. The difference is the refill pack and how long it lasts.

Hayati describe the 4K as a lighter option for short getaways. It holds enough for the trip without carrying more than you need.

If you would rather change packs less often, the Hayati Pro Max Plus 6000 kit has the bigger pack. It also comes in 10mg and 0mg.

How Many Puffs Is the Hayati 4K?

Hayati rate each 4K pack at up to 4,000 puffs, against up to 6,000 for a 6000 pack. How long that lasts depends on how often and how hard you draw. Heavier vapers will get through a pack sooner. The 850mAh battery is recharged between packs and does not need replacing.

How to Refill the Hayati Pro Max Plus 4K

Refilling means swapping in a fresh sealed pack, not pouring in e-liquid. The swap takes under a minute.

1. Take the device, pod and refill cartridge out of the box and remove every seal.
2. Click the pod onto the cartridge until the two lock together.
3. Push the pair into the device until it clicks into place.
4. Check the screen for battery level, then draw to vape. There is no button.

When the pack is empty, pull it out and click in a fresh one. Charge over USB-C when the screen shows a low battery. A cable is not included.

The 4K and 6K share one device. The fixes in our Hayati Pro Max Plus troubleshooting guide apply to both.

The kit comes in 30 flavours, from Summer Dream and Blue Sour Raspberry to Triple Mango. Pick the one your kit arrives with below.
