# Kiwi 2 for travel, battery life, charging and flying with it > Taking a Kiwi 2 travelling? Pen and power bank battery life worked out, charging on the road, pods in your bag and the UK rules for flying with it. A weekend with no socket in sight, a sleeper train, a connection that drags on for hours. Away from home, battery life quickly becomes the real question, long before flavour or draw. The **Kiwi 2** from Kiwi Vapor tackles it in its own way, with a pen that slots into a pocket-sized charging station. What matters is knowing how many days that reserve covers, and how to get it from your bag through airport security without a hitch. ## Is the Kiwi 2 good for travel, the short answer Yes, as long as you take it for what it is, a small mouth-to-lung pod built to last several days away from a wall socket. The **Kiwi 2** pairs a 400 mAh pen with a 1,800 mAh power bank that recharges it up to four times in a row, according to Kiwi Vapor. The maker quotes up to 96 hours of use for the whole kit. Its 1.8 ml pod sits within the UK limit of 2 ml for refillable tanks. On a plane, both the pen and the power bank travel in the cabin, switched off, and are never charged on board. The rest of this guide takes each point in turn. ## The Kiwi 2 kit in your bag, what it brings and what is missing Before packing, it helps to know what the kit brings and what you will need to add. The maker's product page lists six items in the box. ### The pen and its pod The pen, made from aluminium alloy, has no button. The product listings of two retailers, Kumulus Vape and E-liquide-fr, describe a draw-activated device and a pod fitted with a 0.8 ohm coil, for a tight draw. A light vibration accompanies each puff, and an LED warns you when the liquid is about to run out. The pod fills from the side, behind a safety lock. The same retailers note that the power bank can also top up other electronic devices through its USB-C port, a detail that counts on the move. ### What to add before you leave The box holds no wall plug and no bottle of liquid. Kiwi Vapor packs the power bank, the pen, a refillable pod, a drip tip, a cotton filter tip and a USB-C cable. The supplied cable and a phone adapter cover all the charging you will do on the trip. ## Kiwi 2 battery life, the sum to do before you leave The maker's figures are enough to build an estimate before departure. It works best in pen recharges rather than puffs, which depend too much on how each person vapes. ### The pen on its own At 400 mAh, the Kiwi 2 pen has a modest reserve, and how long it lasts depends on how often and how long you draw. Neither Kiwi Vapor nor the retailer listings consulted give a charging time. The simplest habit is to drop it back into the power bank at every break, rather than waiting until it is flat. ### With the power bank Dividing 1,800 mAh by 400 mAh gives 4.5 theoretical recharges. The maker claims four, and the gap most likely comes down to the losses that come with any energy transfer between two batteries. Counting the pen's own first charge, a full kit therefore holds roughly five complete charges. Going by the 96 hours the maker quotes, a three- or four-day trip can do without a wall socket. Beyond that, one overnight charge of the power bank at the hotel resets the count. ## Charging the Kiwi 2 on the road The power bank charges over USB-C, the connector found on many phones. In a country with different sockets, only the travel adapter changes, just as it does for an [18650 battery charger](/uk/18650-battery-charger-travel/) packed in the same bag. At the hotel, charge it on a hard, clear surface while you are in the room. In the car, the USB port does the job during the drive. Once parked, the kit comes out of the car, because a vehicle left in the sun heats up fast and lithium-ion batteries do not cope well with heat. ## Flying with a Kiwi 2, what the rules say The UK government's hand luggage guidance is clear that e-cigarettes may go in hand luggage but not in the hold. It also asks you to charge electronic devices before you travel, since one that cannot be switched on when asked will not be allowed on board. ### The watt-hour sum The Civil Aviation Authority's packing advice says power banks under 100 Wh are generally allowed in the cabin, that you can take two per person, and that they should never be recharged on board. Watt-hours are voltage multiplied by capacity in amp-hours. Kiwi Vapor does not publish the power bank's voltage. Taking 3.7 V, a common nominal value for a lithium-ion cell, gives 1.8 Ah × 3.7 V, or 6.66 Wh, about fifteen times under the threshold. The pen, at 0.4 Ah, comes to 1.48 Wh. ### At security and during the flight The Kiwi 2 pen travels docked in its power bank, switched off, in the bag that stays with you. If your cabin bag is taken for the hold at the gate, the kit comes out first. The CAA also notes that crew may ask you to keep power banks in the seat pocket rather than the overhead locker. Our guide to [taking a vape on a plane](/uk/vape-on-a-plane/) covers every stage of the journey, from packing to landing. ## Pods in your bag A pod filled to the brim is a poor travel companion. Pressure changes in flight can push liquid out of the reservoir, which is why travelling with a lightly filled pod, kept upright, makes sense. Fill it on arrival, at a table. Kiwi Vapor's user guide then asks you to wait about five minutes for the liquid to soak the coil before the first puff. A spare pod, firmly closed, completes the kit, along with your bottles. In the UK, nicotine e-liquid is capped at 20 mg/ml and sold in bottles of 10 ml at most, which keeps each one small enough for a clear liquids bag. A [vape case for travel](/uk/vape-case-travel/) stops everything from mixing with keys and coins. ## FAQ A few questions come up often when taking this kit away for the first time. ### What should you do if the pod has leaked on the way? Take the pod out, wipe the liquid off it and out of the pen's pod slot with a dry tissue, then let everything dry before putting it back. A zip-lock pouch in your bag keeps any further leak away from the rest of your things. ### Can the power bank charge a phone? The retailer listings say it can, through its USB-C port. At 1,800 mAh it gives a phone a boost rather than a full charge, and every such use eats into the pen's reserve. ### Does the Kiwi 2 work with any e-liquid? The Kumulus Vape listing advises a vegetable glycerine content of 50 per cent or less, in other words a fairly thin liquid suited to the kit's 0.8 ohm coil. ### Do you need to declare the kit to the airline? Not for a battery this size, far below the 100 Wh mark. Some airlines set their own limits, though, so check their page before each flight. ### Will the kit cross borders without trouble? That depends on where you are going, since several countries ban e-cigarettes, sometimes even in transit. Check the law at your destination before you book. ## Kiwi 2, getting ready to go The kit brings together what a traveller wants from a small pod, an onboard energy reserve, USB-C charging and a pod that stays under the 2 ml limit. The maker's figures translate into four pen recharges, enough to cover a short trip with no socket. On a plane, the **Kiwi 2** stays in the cabin, switched off and never charged on board, with a power bank of around 6.66 Wh at 3.7 V. The rest happens in your bag, with a lightly filled pod stored upright, as for any vaping kit that goes travelling. ## Next legs of the trip - [Can you take a vape on a plane, from the cabin bag to arrival](/uk/vape-on-a-plane/) - [Countries where vaping is banned, the checks to run before you go](/uk/countries-where-vaping-is-banned/) - [Vape case for travel, keeping your kit in one piece](/uk/vape-case-travel/) Éther Nomade writes for readers aged 18 and over.
