Flying Horse Pen

A flying horse pen and a Flying Horse cart are usually the same object described with different words. This page is about the hardware rather than the liquid: the battery, how the draw works, why the light blinks, and how to stop a pen dying months before the tank is empty.

Why people search for a pen, and what they mean

Ask ten people what they are holding and you will get four names for it. Pen, cart, vape, disposable. The words have drifted apart from their original meanings and it causes real confusion at the point of buying.

Historically a pen meant a slim battery you screwed a cartridge onto. Those still exist, but almost nothing sold under this brand today works that way. What you get is a sealed unit with the battery, tank and coil already assembled, shaped roughly like a pen, which is why the name stuck.

So if you searched for a flying horse weed pen and landed on a page selling carts, nothing is wrong. It is the same device. The practical distinction that still matters is covered in carts vs disposables, and the full range with sizes is on the Flying Horse vape guide.

The battery, which is the part pen buyers care about

On a sealed device the battery is not replaceable, so its condition sets the useful life of the whole unit. That makes it worth understanding rather than ignoring.

These use a small lithium cell, rechargeable over USB. Capacity is matched to tank size, so a ten gram device carries a larger cell than a three gram one. That matching is deliberate, and it is why you cannot meaningfully compare battery specs across sizes.

The failure mode that ends most pens early is not wear from charging. It is being run completely flat and then left sitting for weeks. A lithium cell held at zero charge degrades in a way it does not when stored partly charged. If you are putting a device aside, put it away with some charge in it.

Charging it properly

Three habits extend a pen’s life considerably, and none of them are demanding.

Charge before it dies, not after. Topping up from a third is better for the cell than draining to nothing every cycle. The instinct to run it flat “to be efficient” is borrowed from older battery chemistry and is actively wrong here.

Unplug when it is done. Leaving it connected overnight every night keeps the cell at full voltage for hours, which ages it faster than charging normally.

Use a normal USB port or a low output phone charger. A high wattage fast charger pushes more current than a cell this size expects. It will usually be regulated safely, but there is no upside to trying.

Draw activated, and why there is no button

There is nothing to press. Inhaling triggers a pressure sensor which powers the coil for as long as you draw. That is why the device does nothing at all when you first pick it up, and why a blocked airway makes it seem dead.

The consequence people miss is that draw strength matters. A very hard pull does not deliver more vapour, it pulls liquid past the wick and can flood the coil. A slow, steady draw of a few seconds gives a better result than a sharp one, and it is the single easiest improvement most people can make.

The full sequence, including the first use, is on how to use a Flying Horse cart.

What the blinking light means

The indicator is doing one of three jobs and the pattern tells you which.

A short pulse while you draw is normal operation. Nothing to do.

Repeated rapid blinking when you draw is usually low battery. Charge it and the behaviour stops. If it persists on a full charge, the second most common cause is a blocked airway rather than a fault.

Blinking with no draw at all, or during charging, generally indicates the protection circuit has cut in. Disconnect, let it sit for a few minutes at room temperature and try again. Devices that have been very cold or very hot do this and recover on their own.

If none of that helps, the not hitting guide works through the remaining causes in order of likelihood.

Blocked airways, the most common non fault

A pen that produces nothing, with a healthy battery and no blinking, is usually blocked rather than broken.

Condensation collects in the mouthpiece channel, particularly in cold weather and particularly on devices carried in a pocket. It thickens, and eventually it seals the path. The device is fine, the air simply cannot move.

The fix is unglamorous. Cover the airhole, blow firmly through the mouthpiece onto a tissue, and clear what comes out. Do it twice. That resolves a large share of devices people were about to throw away, and it is worth trying before anything else.

Discretion, which is why the format exists

The pen shape is not styling. It is the reason the category grew.

A sealed unit has no loose cartridge to leak in a bag, nothing to assemble, and it produces far less lingering smell than combustion. It fits a pocket without a case. For a lot of buyers those practical facts matter more than any spec on the listing.

What it does not do is make the product invisible. Vapour is visible, it has a smell while it is in the air, and it is detectable on a workplace test. On that last point specifically, the answer is on do Flying Horse carts show up on a drug test, and the answer is yes. Anyone claiming otherwise is selling something.

A pen against a battery and cartridge setup

The older approach, a reusable battery with cartridges screwed on, still has arguments in its favour and it is worth being even handed about it.

The reusable setup wins on waste, because you keep the battery and replace only the cartridge. It also lets you adjust voltage, which some people genuinely want. Against that, it costs more up front, there is a connection that loosens and leaks, and you have to match cartridge to battery correctly.

A sealed pen wins on simplicity and on nothing to go wrong at the joint, because there is no joint. It loses on waste, which is a real drawback and not one worth pretending away. Recycle the device rather than binning it where a service exists.

For most buyers, most of the time, the sealed pen is the lower hassle option. That is why the market moved.

Weed pen, THC pen, vape pen: which words buy you what

A flying horse weed pen, a THC pen and a vape pen are, in this range, the same hardware. The words differ mainly by who is speaking, and it is worth untangling because the wrong search term sends people to the wrong shelf.

Vape pen is the broadest and the least useful. It covers nicotine devices as well, so searching it alone returns a market you are not shopping in. Weed pen is more specific and is what most buyers actually mean, though strictly the products here are hemp derived rather than marijuana derived, which is the distinction that determines their legal position. THC pen sits in between and is the term most likely to be used by someone already familiar with the category.

What none of the three tell you is potency, and that is the thing worth checking. A weed pen containing a THC-P forward blend behaves very differently from one containing only delta 8, at the same size and often at a similar price. The compounds are compared in THC-P vs delta 8 vs THC-A. Read that before you compare two pens on price, because price alone will mislead you here.

Carrying and storing a pen

Where a pen spends its downtime affects it more than how you use it.

Heat is the main enemy. A car glovebox in summer regularly exceeds anything the device was designed for, and the damage shows up as thinned liquid, leaking and flattened flavour. A pocket close to the body is milder but still warm enough to matter over weeks.

Cold causes a different problem that people misread as a fault. Thickened liquid does not wick properly, so a cold pen produces almost nothing and can taste scorched. It has not broken. Warm it in a hand for a few minutes and it returns to normal.

Store upright with the mouthpiece up where you can. That keeps liquid away from the airway and reduces the mouthpiece blockages described above. The fuller version is in how to store a Flying Horse cart.

One more practical point. Do not carry a pen loose in a bag with keys. The mouthpiece takes the damage, and a cracked mouthpiece leaks in a way that cannot be repaired on a sealed device.

Spotting a counterfeit pen

The hardware is what fakes get wrong first, which makes a pen easier to check than a cartridge.

Look at the seam and the weight. Genuine units feel solid and the housing meets cleanly. Copies frequently have a visible ridge, a rattle when shaken, or a mouthpiece that sits slightly proud. Print quality on the packaging is the other reliable tell, because reproducing fine print consistently is expensive.

The check that settles it is the batch code against a published certificate of analysis. Ours are on the lab reports page. Side by side photographs are in real or fake, and the wider safety question is answered in are Flying Horse carts safe.

Which size pen to buy

Battery life scales with tank size, so the choice is really about how long you want the device to last rather than how it performs.

A 3 gram is the sensible first purchase. A 9 gram is where the value sits for regular use, and it is the most repeated order. The 10 gram exists for heavy use but saves little over the 9. Full pricing is on the price page, and if you want three effects in one body, the 3 in 1 is the one to look at.

Flying horse pen questions

Is a flying horse pen the same as a cart? In practice yes. Almost everything sold under either name today is a sealed all in one device.

Is it rechargeable? Yes, over USB. Charge before it goes flat rather than after.

Why is my pen blinking? Usually low battery, sometimes a blocked airway, occasionally the protection circuit after the device has been very hot or cold.

There is no button. How do I turn it on? You do not. It is draw activated. Inhale slowly and it fires.

My pen is charged but produces nothing. Almost always a blocked mouthpiece. Cover the airhole and blow through it onto a tissue.

Can I refill it? No. These are sealed units, and opening one ruins it.
