# Kiwi pods, the Kiwi Vapor cartridge explained > Kiwi pods from Kiwi Vapor, which cartridge fits the Kiwi 1 or Kiwi 2, 1.8 ml, coil values, the 15 refill rule and the pen's blue K alert. The Kiwi pen recharges inside its pocket power bank, but the cartridge is the part that wears out. **Kiwi pods** raise most of the questions after purchase, which reference to order, how long to keep one, and why the light flashes when liquid is still left. Shops list two lines of cartridges without always saying which device each one belongs to. So we start from Kiwi Vapor's own product pages to sort out this consumable, generation by generation. ## Kiwi pods in brief, a refillable 1.8 ml cartridge **Kiwi pods** are the refillable cartridges of the Kiwi 1 and Kiwi 2 pens made by Kiwi Vapor. You fill them with the e-liquid of your choice, they hold 1.8 ml according to the manufacturer, and the coil is built in, so the whole cartridge is replaced once it is worn. That capacity sits under the 2 ml limit that UK rules set for refillable tanks and cartridges, so there is no separate British version to look out for. On draw, the system aims for a tight mouth to lung inhale, as the retailers we checked in Britain and France describe it. The point that matters before buying is the generation. Kiwi Vapor sells one pod reference for the Kiwi 1, another for the Kiwi 2, and separate pods for the Spark series. ## Which Kiwi pods fit which device Two kits carry the Kiwi name, built on the same idea of a 400 mAh pen stored in a magnetic power bank. Their cartridges are not presented as interchangeable. | Manufacturer data | Kiwi 1 Starter Kit | Kiwi 2 Starter Kit | |---|---|---| | Pen battery | 400 mAh | 400 mAh | | Power bank | 1450 mAh | 1800 mAh | | Full pen recharges | up to 3 | up to 4 | | Material | ABS and polycarbonate | Aluminium | | Total weight | 87.45 g | 105 g | | Pod capacity | 1.8 ml | 1.8 ml | ### Pods for the Kiwi 1 The Kiwi 1 reference comes in packs of three, with three cotton filter tips, and Kiwi Vapor describes it as a mesh coil cartridge. The manufacturer does not publish its resistance, which a British and a French retailer both list at 1.2 ohm for a tight draw. ### Pods for the Kiwi 2 The Kiwi 2 cartridge comes in packs of two, with two cotton tips. Its listing gives 1.8 ml, a 0.8 ohm coil, a plastic body, a secured filling cover and electronic overheating protection. ### What about the Spark series The Kiwi Spark pens, a single tube format with no separate power bank, take their own pods, listed separately in the manufacturer's catalogue. This guide does not cover them. ## What comes in a box of Kiwi pods Both references share a detail that is easy to miss when ordering. Each cartridge arrives with its own cotton filter tip, which fits in place of the drip tip supplied with the kit. The pen therefore takes two kinds of mouthpiece. The polycarbonate drip tip can be cleaned and kept, while the cotton tip gives a softer feel on the lips and is swapped along with the cartridge. Ordering pods means renewing your tips at the same time, with nothing extra to buy. On liquids, Kiwi Vapor says its pods work with every flavour. The retailers we checked advise an e-liquid with at least 50 per cent propylene glycol, which rules out thick, high-glycerine blends that suit this type of coil poorly. In the UK, nicotine e-liquid is capped at 20 mg/ml and sold in bottles of 10 ml or less. ## How long Kiwi pods last, the 15 refill rule For the Kiwi 2, Kiwi Vapor publishes a figure that few listings repeat. A cartridge should be replaced after 15 refills, and the pen flags that threshold on its own. Measured against the capacity, that is 27 ml of liquid per cartridge, or 15 times 1.8 ml. The figure helps you reorder at the right pace and judge a cartridge that fades early, rather than relying on taste alone. For the Kiwi 1, the manufacturer gives no equivalent number. The same logic still applies, since a built in coil wears with the liquid that passes through it, and a sweet recipe generally clogs the wick faster than a menthol or tobacco style one. ## Filling and priming Kiwi pods without burning them Filling is simple, but priming decides how long the cartridge lasts. Three instructions from the manufacturer stand out. ### Let the cotton soak With a new cartridge, Kiwi Vapor asks you to wait at least five minutes after the first fill before vaping. A coil fired on cotton that is still dry picks up a burnt taste that does not go away. ### Keep the pen upright The manufacturer advises against vaping with the pen upside down, a position that dries the cotton and triggers the Kiwi 2 alert. To check the level, turn the device over for a moment while it is not in use and look at the liquid, without removing the cartridge. ### Remove the pod as little as possible Each removal weakens the contact between pod and pen, according to Kiwi Vapor. The Kiwi 1 lets you check the liquid level without taking the cartridge out. If a pod still loses liquid despite these precautions, our guide to [pod leaking fixes](/uk/pod-leaking-fixes/) goes through the usual causes, and our explainer on [MTL vaping in a pod](/uk/mtl-vaping-pod/) covers the tight draw these cartridges are built for. ## The Kiwi 2 blue K, an alert that is not only about liquid The Kiwi 2 warns with five flashes of its blue K shaped LED, paired with a vibration, when the liquid nears the low threshold. The manufacturer calls this the Low Liquid Reminder. The same signal can light up with a full cartridge, though. Kiwi Vapor lists the causes, namely the wear of 15 refills, heat build up after long use, excess condensation at the base of the pod, a liquid whose thickness changes with temperature, or a new pod the pen is still calibrating. In that last case, simply vaping again lets the device recalibrate. Before throwing a cartridge away, it is worth wiping its base and trying it a second time. If the K comes back on a cartridge past 15 refills, replacement is the answer.

Here are the answers drawn from the manufacturer's pages. ### Can a Kiwi 1 pod go in a Kiwi 2? Kiwi Vapor sells two separate references and states no cross compatibility. The retailers we checked list the Kiwi 2 cartridge for the Kiwi 2 only. Without written confirmation, the reference made for your own device is the safe choice. ### Do Kiwi pods charge over USB-C? The cartridge holds no battery. It is the pen that charges, either in its magnetic power bank or directly through a USB-C cable, according to the manufacturer. ### What warranty covers a Kiwi kit? Kiwi Vapor offers 12 months, extended to 24 months if the device is registered in the dedicated area of its website. For the Kiwi 2, registration has to happen within 90 days of purchase. Pods are consumables and are simply replaced. ### Why does the Kiwi 2 vibrate while I inhale? The Kiwi 2 gives light vibrations during each draw, a feature the manufacturer calls Smart Vibration. It acts as tactile feedback and also carries the low liquid alert. ### Do I need a fresh pod to change flavour? The manufacturer does not require it. A strong menthol or very sweet flavour does mark the cotton, though, and moving to a delicate liquid in the same cartridge can leave an aftertaste over the first few refills. ## Kiwi pods, what to keep in mind A Kiwi cartridge is chosen first by the generation of its pen, Kiwi 1, Kiwi 2 or Spark, before any question of taste. The rest follows from that choice, 1.8 ml of capacity, a 1.2 or 0.8 ohm coil depending on the reference, and cotton tips included in the box. The 15 refill rule published for the Kiwi 2 finally gives a concrete marker for judging wear on **Kiwi pods**, and a reminder that a built in cartridge, like any open pod, is managed through its consumable as much as through its device.
