Two refill-bottle kits, both opened on the same bench: one better described as 2+10, the other carrying a 0+10 designation. Similar promise — very different execution.
Quick answer: The Elf Bar MAX and the Vaporesso DOJO 0+10 are related activation-refill kits, but they should not be collapsed into the same label. The Elf Bar MAX is a 2+10 design: a 2 mL prefilled pod plus a 10 mL oil bottle. The Vaporesso DOJO 0+10 is closer to the industry 0+10 idea: a dry or near-dry core paired with a 10 mL oil bottle that the user activates before vaping. Both use clever reservoir-to-core wetting mechanisms, but the resemblance ends there. Elf Bar has the cleaner build — a recyclable battery bay, engineered condensation drainage, and tidy modular assembly. DOJO has the more ambitious feature set (adjustable airflow and power, second-bottle support) but underdelivered where it counts: its “1,000 mAh” cell gave us only ~826 mAh usable, and our panel found the draw weak.
Head-to-head: what the teardowns show
| Elf Bar MAX | Vaporesso DOJO 0+10 | |
|---|---|---|
| Refill mechanism | 2+10 piston activation — bottle opens and wets core | 0+10 push-to-fill — opens path + pressurises dry core, reseals |
| Battery | 650 mAh (confirmed) | 1,000 mAh nominal → 826 mAh usable (to 3.27 V), our unit |
| Controls | Simple, fixed | Adjustable airflow + ECO/PWR power |
| Build / recycling | Modular, solder-free, removable battery bay | Tidy CMF; metal oil-cup collar |
| Leak control | Dedicated condensation drainage channel | Anti-leak “racetrack” wick — but mouthpiece wick siphons the core |
| Draw / experience | (Not sensory-tested) — coil-dependent | Panel: airy, low vapour, faint aroma, weak sweetness |
| Lock-in | Proprietary bottle | Proprietary bottle |
| Parts | 41 | 33 |
Note: we ran a sensory panel on the DOJO but not the Elf Bar MAX, so we compare the DOJO’s measured draw against the Elf Bar’s untested experience — we don’t claim the Elf Bar tastes better, only that the DOJO measured poorly.
Refill: both clever, slightly different
Both kits solve the same practical problem: a separate oil bottle or reservoir has to be connected to an atomizer chamber before use, so the wick and coil are wet enough to vape. The Elf Bar MAX uses a piston in a 2+10 format; the DOJO uses a push-to-fill closer to a 0+10 format, opening the oil path, pressurising, and resealing when you pull the mouthpiece out. Engineering-wise this is the strongest part of both devices, but “instant” should be read as brand shorthand for activation and wetting, not as the category definition.
Battery: the clearest separation
This is where they diverge. The Elf Bar’s 650 mAh cell is modest but confirmed, and sits in a removable, recyclable bay. The DOJO’s cell is marked 1,000 mAh, but discharged to a 3.27 V cutoff on our unit it delivered 826 mAh usable — a reminder that nominal mAh isn’t usable runtime. Neither is huge; the Elf Bar’s smaller-but-honest number plus recyclable bay is the more reassuring story.
Leak control: engineered vs. fighting itself
The Elf Bar MAX actively routes condensation away from its sensor with a drainage channel. The DOJO adds anti-leak wicking for its second-bottle feature — good intent — but we also found its mouthpiece wick siphons liquid back out of the core, a design that works against itself and raises seepage risk. For why this matters, see why vapes leak.
Which activation-refill kit should you buy?
- Choose the Elf Bar MAX if you want the dependable 2+10-style everyday kit: honest battery, recyclable bay, leak-aware design, simple use.
- Choose the Vaporesso DOJO 0+10 if you specifically want the true 0+10-marked format, adjustable airflow/power, and second-bottle flexibility — and you accept a shorter real battery and a weaker draw on the unit we tested.
Both lock you into a proprietary bottle, so neither wins on liquid freedom. One is 2+10 and the other is 0+10, but both show the same market direction: separate the liquid reservoir from the core, then make the user activate the path. For the category basics, start with what a 0+10 vape is.
FAQ
Is the Elf Bar MAX or the Vaporesso DOJO 0+10 better?
On our bench, the Elf Bar MAX is the more dependable 2+10 build — confirmed battery, recyclable bay, engineered leak control. The DOJO is the closer 0+10-marked format and has more features (adjustable airflow/power, second bottle), but measured a shorter usable battery and a weaker draw.
Do both have brand-marketed “0-second” refilling?
Both use real activation mechanisms that wet the coil after bottle insertion or mouthpiece activation, but “0-second” is marketing shorthand. Users should still treat the process as reservoir connection plus core wetting.
Which has the better battery?
The Elf Bar’s 650 mAh is smaller but confirmed; the DOJO’s 1,000 mAh nominal cell gave only ~826 mAh usable on our unit. Neither is large, but the Elf Bar’s is the more honest figure.
