Fifty millilitres against 300,000 draws is a lean ratio, and the UWIN SHISHA 300K does not hide it: this is a device built for full, open draws, and the arithmetic follows.

The arithmetic of 300,000

Fifty millilitres across a 300,000 rating is 0.17ml for every thousand draws. That is a consequence of the draw style rather than a virtue.

A direct-to-lung pull at this airflow moves a lot of vapour, so the supply is spent in fewer, larger draws. Anyone expecting 300,000 separate sessions has misread the number; anyone who reads it as a measure of how long the device will sit on a table has it about right.

Adjustable airflow

The intake can be opened or tightened from the base. It does not turn the device into a mouth-to-lung model, but it does let the draw be tuned between a looser and a more controlled version of the same thing.

That matters more here than on a smaller device, because the coil and the cell are both sized for volume. Closing the airflow down is how you slow the rate at which the supply goes.

1000mAh and 50ml

The cell is 1000mAh, which works out at 50ml for every amp-hour. That is a middling load: enough cell to hold output through an open draw, not so much that the body becomes a brick.

Charging is USB-C. On a device this long-lived, the cell is the pacing item and the screen is what tells you where it stands. A full charge does not finish the supply, and the supply does not finish a charge; the two run down on their own schedules.

The LCD and the body

A screen set into the curved body reports charge and remaining supply. The shape is a curved column rather than a box, with the mouthpiece at the top and the screen low down.

The proportions follow the cell and the reservoir. Neither is small, and the body is shaped around both rather than tapered to look slimmer than it is.

The curved body

The chassis is a curved column rather than a straight one, with the screen set into the front and the mouthpiece at the top. The curve is ergonomic before it is decorative: it sits against the palm instead of standing off it.

It also means the device does not roll. Set down on its base it stays put, which matters on a table where a shisha session tends to happen.

Ten profiles, one per device

The list runs ten, built around the profiles a shisha range carries: two apple, grape mint, lemon lime, mixed berry, gum mint and a cherry note among them.

Each device holds one profile for its whole life. The strength range runs from zero to 5%, so the output is settled at order along with the taste, and neither can be changed afterwards. That is the trade for a device this long: it commits early, keeps going, and asks nothing of you in between, which is the point.

Puff counts are manufacturer ratings taken at short draws and vary with draw length and frequency.

Buying and delivery

UseeVape supplies the UWIN SHISHA 300K in single units and in bulk, with wholesale pricing applied as the quantity rises. Orders typically start at around ten units; the price for your quantity is shown on the product page rather than fixed here, so it stays correct when pricing moves.

Stock is held across European and overseas warehouses, and the dispatch location depends on live availability at the time of the order, so no specific country warehouse is promised in advance. Confirming quantity and your taste selection together is the quickest route to a dispatch date.

Questions buyers ask

Is this a mouth-to-lung device?
No. It is direct-to-lung. The adjustable airflow changes how open the draw is, not the style.

Why is 50ml not as long-lasting as it sounds?
Because each draw is full. At 0.17ml per thousand, the supply is spent faster per pull than on a tighter device.

How long does a charge last?
A session at a time rather than a week. The 1000mAh cell is sized for an open draw, and the screen shows where it stands.

Can I close the airflow completely?
It adjusts across a range rather than closing shut. The device is designed to be drawn open.
