No, and it is not worth trying. The tanks are sealed for TPD compliance, and prising one open usually wrecks the coil and voids any warranty. On the pod-based models the right move is a fresh prefilled pod; on the sealed devices, recycle the unit once the flavour fades.
The headline figures, 4,000 up to 25,000, come from lab-style short puffs, so treat them as a maximum. Long, deep draws can halve the real count. Even allowing for that, the cost per puff undercuts old-style disposables by a wide margin.
The Hayati devices we sell are TPD compliant, MHRA notified and rechargeable, which keeps them on the right side of the June 2025 single-use ban. Buy from a UK retailer like us rather than a marketplace listing; the brand is heavily counterfeited and fakes skip every one of those checks.
First give it a proper charge on a USB-C cable and a mains plug rather than a laptop port; a fully drained battery can take a few minutes to show signs of life. If it will not wake after an hour on charge, the cell has failed: stop using it and take it to a vape recycling point rather than binning it.
It is Arabic for “my life”, a common term of endearment. The name stuck because the brand aimed its devices at flavour lovers rather than hardware tinkerers, and it clearly worked.
