Description
Introduction
The Innokin Kroma 217 Z Force Vape Kit is a refillable 100W box mod and sub-ohm tank for direct-lung vaping, priced at £39.99. Best for vapers who want big flavour from one 21700 battery. Not ideal for anyone after a tight, cigarette-like draw, or a kit with a battery in the box.
The Innokin Kroma 217 Z Force Vape Kit pairs the Innokin Kroma 217 mod with the 2ml Innokin Z Force tank and two ZF mesh coils. It runs on one external 21700, 20700 or 18650 battery, sold separately. This is the Innokin Kroma 217 single-battery mod kit, not the Innokin Kroma Z pod kit or the Innokin Kroma R.
Key Facts
The Innokin Kroma 217 Z Force Vape Kit reaches up to 100W with a 21700 battery.
The Innokin Kroma 217 Z Force Vape Kit takes one external 21700, 20700 or 18650 battery, which is not included.
The Innokin Z Force tank in the UK kit holds 2ml of e-liquid and fills from the top.
The Innokin Kroma 217 Z Force Vape Kit includes one ZF 0.2Ω coil (50-80W) and one ZF 0.3Ω coil (30-45W).
The Innokin Kroma 217 mod charges by USB-C at 5V/1.7A.
Innokin Kroma 217 Kit: Key Specs Customers Check
Battery: one external 21700, 20700 or 18650, not included. Order a battery with the kit, or it will not fire out of the box.
Power: up to 100W with a 21700. Independent reviewers measured an 80W ceiling on an 18650, which still covers both supplied coils.
Tank: Innokin Z Force, 2ml (UK TPD size). Slide the top cap and fill through the self-sealing membrane.
Coils supplied: ZF 0.2Ω (50-80W) and ZF 0.3Ω (30-45W). Both are dual mesh and push in by hand, with no threads.
Charging: USB-C, 5V/1.7A. Innokin publishes no charge time; an external charger is the kinder habit for the battery.
Size: 132 x 45 x 30mm with tank, 86mm tall without. The body is zinc alloy.
Pick Your Inhale: DTL or RDL on the Innokin Kroma 217 Mod
This kit is built for direct lung (DTL): vapour goes straight into the lungs, like a deep breath. Restricted direct lung (RDL) is the same style with tighter airflow. Both coils are sub-ohm (below 1.0Ω resistance), which makes more vapour.
ZF 0.2Ω, DTL, 50-80W: warm, dense clouds. Reviewers settled at 65-70W with the airflow open.
ZF 0.3Ω, RDL, 30-45W: cooler, uses less e-liquid and battery. Close the airflow about halfway.
Neither coil gives MTL (mouth to lung, a tight cigarette-like draw).
Key Features
Coil+ mode: sends a short pulse of current after each puff. Innokin designed it to extend coil life.
Refresh mode: pulses the coil at 40% of the set wattage to bring flavour back.
Automatic juice flow control: a spring gate shuts when the coil comes out, so the coil can be swapped with e-liquid still in the tank.
Wattage or voltage control: two simple modes on a bright screen. There is no temperature control or bypass mode, a limit the Planet of the Vapes review flags for experienced users.
Innokin ZF Coils and E-Liquid Pairing
Use 70% VG or higher e-liquid; thick liquid suits mesh coils at this power, while thin 50/50 liquid can flood them. A shortfill (a large nicotine-free bottle with room to add a nic shot) is the usual choice: see 70/30 high VG e-liquids. Most sub-ohm vapers use 3mg or 6mg freebase nicotine. Strong 20mg nic salts feel harsh at 30W and above.
Battery, Coil Life and Running Cost
Battery life: Planet of the Vapes got about a working day from a 21700 at 66W, and into the evening at 45W. Ecigclick got about four hours of mixed use from an 18650.
Coil life: reviewers ran both coils for two weeks with no flavour drop. Heavy use and sweet e-liquid shorten that.
Running cost: Innokin ZF replacement coils come in packs of 5, so a pack covers roughly ten weeks at that rate. Shortfill e-liquid costs far less per ml than prefilled pods.
Battery sold separately: a common question in UK retailer reviews is why the kit arrives without one. Pick a cell from 18650 and 21700 vape batteries.
Compatibility and Refills
The Innokin Z Force tank takes Innokin ZF coils only (0.2Ω and 0.3Ω). Innokin Z coils for Zenith and Zlide tanks do not fit. The tank is 24mm wide with an 810 drip tip, and spare Innokin Z Force tanks are sold separately. The 2ml tank empties quickly at high wattage, so keep a bottle nearby.
How to Set Up the Innokin Kroma 217 Z Force Vape Kit
Slide the battery door open and insert a charged battery, positive (+) end going into the mod first.
Drip a few drops of e-liquid onto the coil’s cotton, then push the coil into the tank base.
Slide the top cap, fill through the membrane and close it. With wide bottle nozzles, lift the drip tip off first.
Leave it to soak for about 10 minutes. Innokin gives no set time; reviewers allow 10 to 15.
Press the fire bar 3 times to switch on.
Start at the low end of the coil’s range (50W or 30W) and work up.
Hold + and – together for the menu: Coil+, Refresh and settings.
How to Make It Last Longer
Stay inside the coil’s wattage range. Owners on the E-Cigarette Forum report the 0.3Ω coil can run dry at 45W; dropping to 30-35W fixes it.
Refill before the tank runs empty and pause between long puffs so the cotton re-wets.
Check the battery wrap for nicks or tears and replace a damaged cell.
Do not store the battery flat. Innokin advises against leaving it fully discharged.
Best Colours
The Innokin Kroma 217 Z Force Vape Kit comes in five finishes. Stealth Black and Carbon Fiber are the discreet picks for pocket carry. River Wood suits vapers who like a classic mod look, while Mariana Blue and Glass Fiber appeal to collectors.
