Aspire PockeX, the drip tip and the draw up close
The Aspire PockeX has been on shop shelves for years, and almost every listing describes it through its battery and its tank. Very few say much about the part that actually meets your lips. Yet on the Aspire PockeX, the mouthpiece, the airflow and the coil form a single circuit, and that circuit decides how the draw feels. The useful work is separating what the manufacturer states from what retailers add on top.
The Aspire PockeX in one paragraph
The Aspire PockeX is a pocket all-in-one tube. Aspire’s own site lists just two products in the series, the PockeX and the PockeX Box, and shops also sell the tube as the PockeX Pocket AIO or spell it Pocke X. These are all the same device.
Aspire’s official specification sheet, the source for every figure here unless stated otherwise, gives the numbers. The tube measures 117.7 mm tall and 19.7 mm across, weighs 86 g and has a stainless steel shell. Its built-in 1500 mAh battery fires in bypass mode, with no power setting at all. The 2 ml tank pairs a glass tube with a stainless steel cover, which sits exactly on the UK limit for refillable tanks.
On the mouthpiece side, the thinking fits in one line. A wider drip tip and a larger top airflow are meant to increase vapour production. Everything below follows from that choice.
The Delrin drip tip on the Aspire PockeX
The mouthpiece is the least documented part of the tube, even though it shapes comfort more than anything else. Two facts are confirmed, a third remains unclear, and all three matter before you think about swapping it.
A wide tip in Delrin
The official exploded view names the part “Delrin Drip Tip”. Delrin is an engineering plastic that conducts little heat, which is why it turns up so often on kits that produce warm, dense vapour. Our guide to drip tip materials sets it against Ultem, stainless steel and resin.
The width is stated without a figure. The tip is only described as “wider”, and one shop listing repeats the idea of a wide tip with a generous draw. None of the sources checked gives the internal bore, even though that bore sets how much room the vapour has on its way out.
What the listing leaves out
The official sheet does not say whether the tip takes a standard 510 drip tip, and shops disagree. One lists a 510 connection, another a mouthpiece specific to Aspire, a third simply a “single” drip tip. Without sources that agree, the sensible assumption is that the original mouthpiece is the only one designed for this top cap.
That disagreement has a practical consequence. Before ordering a replacement sold as compatible, check that the listing names the PockeX specifically, rather than “Aspire tubes” in general.
Top airflow and what it does to the draw
On most tanks, air comes in at the base, underneath the coil. The PockeX does the opposite, with its airflow at the top of the device around the top cap, as several shop listings also confirm. Air travels down to the coil and then back up to the mouthpiece.
This layout has a well known benefit. The air inlets sit above the e-liquid, away from the base, which lowers the risk of leaks through the vents. The trade-off is a longer air path, so the draw depends more heavily on which coil is fitted.
Then there is the question of adjustment, where listings disagree. Several describe the airflow as fixed, at least one mentions a ring you turn for a more or less airy vape, and the official sheet mentions no adjustment at all. The safe approach is to buy the tube assuming the opening cannot be changed, and to tune the draw through the coil instead.
0.6 or 1.2 ohm, two draws from one mouthpiece
Because the battery fires in bypass, the only way to change power is to change the coil. Aspire offers two for the Aspire PockeX, both from its U-Tech range, which the brand links to the Nautilus X.
The 0.6 ohm in 316L steel
Fitted from the factory, this coil is made of 316L stainless steel and described as a good balance between flavour and vapour. Shops list it for an 18 to 23 W range. Combined with the open top airflow and the wide tip, it gives the freest draw the tube can offer.
The 1.2 ohm in Kanthal
The second coil is Kanthal, and it is recommended for e-liquids with a higher nicotine strength. In the UK, nicotine e-liquid is capped at 20 mg/ml and sold in bottles of 10 ml at most. Ohm’s law explains why this coil runs cooler. At a given voltage, power equals V²/R, so doubling the resistance halves the power. At 3.7 V, the nominal voltage of a lithium-ion cell, that works out at about 22.8 W on the 0.6 ohm against 11.4 W on the 1.2 ohm.
Our explainer on MTL vs DTL and the drip tip bore covers how coil and bore work together. On this tube the mouthpiece never changes, so the coil does all of the work.
Top filling, seen from the mouthpiece
Aspire chose to fill through the top cap. You unscrew the upper section, mouthpiece included, and pour the e-liquid in below the maximum line. Two shop listings add that the coil stays attached to the top cap once it is removed.
That detail matters for upkeep. Mouthpiece, airflow and coil come out as a single block, giving access in one go to every part that condensation tends to clog. The method in our guide on how to clean a drip tip then applies to the whole top cap, with the coil taken out first.
Before the first puff, the cotton needs to soak for 2 to 3 minutes, depending on how thick the liquid is. A new coil fired too early gives a burnt taste that no mouthpiece can fix.
Who the Aspire PockeX format suits
The tube is aimed first at people who want a device without menus. It switches on and off with five clicks, a single button fires the coil, and an indicator turns from blue to red once the charge drops below 30 per cent. Recent versions charge over USB-C, older ones over micro USB.
Our view is clear. For a free draw and dense vapour in a pocket format, the PockeX earns its place thanks to its wide, heat-shy mouthpiece. For a tight draw that can be adjusted precisely, a device with an airflow ring below the coil will serve better, because the PockeX airflow cannot be relied on to adjust.
FAQ
Five questions come up again and again about the mouthpiece and the draw on this tube.
Does the PockeX Box use the same mouthpiece?
Nothing confirms it. The PockeX Box is a different device, built side by side, with its own page on Aspire’s site. Before moving a mouthpiece from one to the other, check the compatibility stated on the listing for that part.
Does the PockeX mouthpiece get hot?
Delrin conducts little heat, which is why it was chosen for a device that makes dense vapour. The metal top cap around it can still warm up during long, close puffs, as on any bypass device. Leaving a gap between puffs gives the metal time to cool.
Can I block the airflow to tighten the draw?
It is not a good idea. Blocked airflow starves the coil of the air that cools it, which encourages a burnt taste and liquid creeping up the chimney. For less dense vapour, the 1.2 ohm coil, which draws half the power at the same voltage, is the route the range provides.
Why does liquid reach the mouthpiece?
Most often it is condensation building up in the chimney, or a tank filled above the maximum line. Taking off the top cap and wiping inside the mouthpiece deals with the first. Respecting the fill line prevents the second.
Is the 2 ml tank legal in the UK?
Yes. UK rules cap refillable tanks at 2 ml, and the PockeX is listed at exactly that capacity.
Aspire PockeX, a draw set by the coil
The tube is best judged by its air path rather than its battery. A wide Delrin tip, top airflow with no confirmed adjustment and two coils with very different power levels decide the whole draw, with no menu and no adjustment you can count on.
Choosing a coil therefore means choosing a draw. On the Aspire PockeX, that small detail makes all the difference, and it is exactly the kind of part this magazine likes to examine up close.
