Dual Flavor Disposable Vapes — Two Tanks in One Device, Compared
A dual flavor disposable vape carries two separate e-liquid tanks, each with its own coil, and lets you pick which one you draw from — or blend both. Only a handful of devices actually do this; many products marketed as "dual" or "switch" mean two power modes, two coils, or a menthol chamber. Below: how the mechanism works, the 7 devices we could verify hold two flavors, and what to check before buying. We stock only Flum, so read the Flum row as one option in the category, not the verdict.
A true dual flavor disposable has two independent tanks and two coils; you switch tanks with a toggle, a button that sets a blend ratio, or a rotating mouthpiece. As of 2026-09-17 the two-flavor devices we could confirm on the US market are the Flum UT Bar Pro 50K (Up to 50,000 (Eco) · ~25,000 (Turbo), 760 mAh), Adjust MyFlavor 40K, Kado Bar Flavor Adjust 40K, KangerTech Subox Mix 50K, PYRO Duo 30K, OXBAR DualBlend 35K and Lost Mary Combo 20000. Puff ratings are totals across both tanks, so each flavor lasts about half the headline number.
How a two-tank disposable actually works
Inside the shell are two pre-filled tanks, each with its own mesh coil and its own wick. The battery, airflow path and mouthpiece are shared. What differs between brands is how you choose the tank:
- Toggle switch. A physical switch or one-tap button routes the draw to tank A or tank B. The screen shows which tank is live and how much juice is left in each. This is the Flum UT Bar Pro 50K approach; Flum also lists a Mix Mode that fires both.
- Blend ratio. A button steps through ratios (100/0, 90/10, 50/50 and so on) so the two flavors mix in the vapor rather than alternate. Adjust MyFlavor 40K and OXBAR DualBlend 35K work this way; Kado Bar's Flavor Adjust 40K advertises 15 levels.
- Rotating mouthpiece. Turning the drip tip lines it up with one tank or the other. KangerTech's Subox Mix 50K uses this, with its second tank tuned as a low-vapor mode.
- Slider. Lost Mary's Combo 20000 pushes a slider to one side for a single tank or centres it for both.
Two things follow from the design. First, the headline puff count is the total of both tanks, so a "50,000 puff" dual device gives you roughly 25,000 of each flavor. Second, the two tanks are usually not the same size, and some brands do not publish per-tank volume at all — the table marks those as not published rather than guessing.

Flum's row is read from our store at build time (price and in-stock count included). Other brands' figures come from manufacturer or major retailer listings we opened on 2026-09-17; we list no competitor prices because retailer sale prices swing too much to compare fairly.

Reading the table honestly
On total puff rating the Flum UT Bar Pro 50K and the KangerTech Subox Mix 50K sit at the top of the set, but they get there differently: Flum's number is an Eco-mode rating that drops to roughly 25,000 in Turbo, while KangerTech's second tank is a deliberately low-vapor mode, so its two flavors are not equal-output. The Adjust and Kado Bar 40K devices trade some puffs for a blend ratio, which is the feature to want if you like mixing flavors rather than alternating them. Battery is the one spec where Flum is mid-pack — 760 mAh against 900–1,500 mAh elsewhere — though all of them recharge over USB-C, so capacity mostly decides how often you plug in, not how long the device lasts.
Lost Mary's Combo 20000 is worth knowing about but is a 2% nicotine UK/EU product with thin US retail presence; we include it because it is one of the few devices from a major brand that is genuinely two-flavor.
What is marketed as "dual" but is not two flavors
Because "dual" and "switch" sell, a lot of single-flavor devices use the words. None of these hold two flavors: Raz RYL 35K (one 16.5 mL tank, one flavor); Geek Bar Pulse X2 (single tank; 'dual' = coils/modes); Lost Mary MT35000 Turbo (single tank, dual mode); Mr Fog Switch SW15000 ('switch' = 10 W / 20 W); Off-Stamp SW16000 (one pod at a time); Off-Stamp X-Cube (flavor + menthol chamber, not two flavors); Hyppe Infiniti 50K, Geak Nexx 40K, Pillow Talk SC40000 (single flavor with ice / sweetness / nic sliders); Foger Switch Pro (single replaceable pod). If a listing says "dual" but shows one flavor per SKU, it is one of these.
What to check before you buy a two-flavor disposable
- Puffs per flavor, not per device. Halve the headline number, and check whether it is quoted in an eco/low-power mode.
- Tank sizes. Some brands split the juice unevenly or do not publish it. Unpublished is not zero, but it is not a spec you can compare either.
- Switch type. Toggle (alternate flavors) versus ratio blend (mix them) is a real difference in how the device feels day to day.
- Equal output. Ask whether both tanks fire at the same power. A "vaporless" or "stealth" second tank is a different product from two full-strength flavors.
- Nicotine. US market devices in this set are 5% salt; the Lost Mary Combo is 2%.
- Pairing menu. Two-tank devices sell in fixed pairs. Flum lists 43 UT Bar Pro 50K variations, a mix of two-flavor combos and single flavors in both tanks — the full list with live stock is on the Flum UT Bar flavors page and in the flavor decoder.

Frequently asked
What is a dual flavor disposable vape?
A disposable with two separate pre-filled tanks and two coils in one body. A switch, blend button, slider or rotating mouthpiece decides which tank you draw from, so one device gives you two flavors (or a mix) without carrying two vapes.
Which disposable vapes have two flavors?
Verified as of 2026-09-17: Flum UT Bar Pro 50K, Adjust MyFlavor 40K, Kado Bar Flavor Adjust 40K, KangerTech Subox Mix 50K, PYRO Duo 30K, OXBAR DualBlend 35K and Lost Mary Combo 20000. Devices like the Raz RYL 35K, Geek Bar Pulse X2 and Mr Fog Switch are single-flavor despite the naming.
Does a 50,000-puff dual flavor vape give 50,000 puffs of each flavor?
No. The rating is the total across both tanks, so it is roughly 25,000 per flavor, and on the Flum UT Bar Pro 50K the 50,000 figure is the Eco-mode rating (about 25,000 total in Turbo).
Can you mix the two flavors?
Depends on the device. Blend-ratio designs (Adjust, OXBAR, Kado Bar) mix in the vapor at set ratios; the Flum UT Bar Pro 50K lists a Mix Mode that runs both tanks; KangerTech's rotating mouthpiece and toggle-only designs alternate rather than blend.
How much e-liquid is in a dual tank disposable?
Between 20 and 50 mL total in this set, usually split evenly. Some brands, Flum included for the UT Bar Pro 50K, have not published the tank volume; we list those as not published instead of guessing.
