There have been three generations of coil technology. Use of standard wire coils was replaced with a single mesh, which eliminated the convex shape of the heating surface, allowing for more even vaporization. The dual mesh coils seem to be becoming a common feature of flagship pod systems and are intended to deliver even more flavor and vapor. When deciding between dual mesh vs single mesh vape technology, the marketing claims are often 2x the flavor and 2x the life cycle, versus single mesh. Is that a real technical gain, or just a bigger number on a spec sheet? The key lies in the way the coils are designed and how a device operates them — and that's what this comparison explains, in the context of OXVA's NeXLIM Series, a dual mesh system that operates in a refillable pod system.
Single Mesh vs Dual Mesh Vape Coils: How Each Technology Works
How Single Mesh Coils Work
The single mesh coil is made with a flat heating element that is perforated rather than the traditional round wire. The surface of the e-liquid is flat, so more heat is spread out across it than with a round wire, resulting in less of a “dry hit” and a cleaner draw. Another advantage of wicking is that it is consistent; instead of having to rely on a wrapped coil to pull liquid from one direction, the mesh surface pulls liquid evenly. It’s the method of heating used by most of the traditional pod systems that still exist today and it’s the most reliable and maintenance-free choice for vapers who don’t need the versatility of various modes.
How Dual Mesh Coils Work: Key Dual Mesh Coil Benefits
The difference between a dual mesh coil and a single flat mesh coil is that it contains two different mesh coils as opposed to just one meshed surface in the same cartridge. In either mode, the two meshes release the vapor and/or flavor at the same time, or alternately, to distribute the heat load between two meshes, thus prolonging the element’s lifespan. The extra surface area introduced by a second heating element creates more surface area for the e-liquid to vaporize over, which is often cited as the reason for a more full-bodied and nuanced taste compared to a one-heating surface. And not just because the coil is running at higher wattage, that’s where the dual element design and modeswitching comes in.
Single Mesh vs Dual Mesh: Performance Comparison Table
Single mesh coils are a good, affordable option for simple vaping. The dual mesh coil core advantages are in place to address a certain drawback: obtaining more from the same pod without just cranking up the watts, which can cause coils to burn out quicker.
The selection of coil resistance also needs to be considered. Single mesh cartridges are usually available in just one or two standard resistances that works for vapers who prefer a single draw style. The dual mesh cartridges will typically offer a broader spectrum, like OXVA’s NeXLIM pods which are available in 0.6Ω, 0.8Ω and 1.2Ω, from a tighter mouth-to-lung draw to a looser restricted direct-to-lung vape from the same cartridge. That range offers greater flexibility to dual mesh systems to provide the wattage and airflow that a vaper wants when they inhale.
The Breakthrough: A Long-Lasting Vape Pod System with Dual Mesh
Dual mesh heating has been around for a while, but prior to this, it was limited to high-power box mods and single-use disposables, as battery size and coil price were not as much of an issue. The more challenging engineering feat was to fit two mesh elements into a small, replaceable pod cartridge without compromising battery life or reliability.
With UNITECH 3.0, OXVA addressed this with its dual mesh coil technology packaged in a refillable pod with two different firing modes:
-
The BOOST Mode simultaneously activates both the mesh elements to create the highest vapor density and flavor.
-
ECO Mode ECO Mode changes between the two meshes, prolonging the life of the coils up to 200% longer than a conventional single-mesh pod system, according to OXVA.
This is the system that underlies the dual mesh system, allowing for the use of this dual mode in a refillable pod; the coil will not be used at full strength all the time, but will only be used at full strength when the vaper selects the BOOST mode, which will help to preserve the strength of the coil in ECO Mode for regular use. UNITECH 3.0 cartridges also feature a larger condensate chamber and multi-layer leak-proof design to keep up with the increased e-liquid flow through firing two mesh elements. In reality, this engineering is manifested in refill numbers, OXVA’s UNITECH 3.0 cartridges are expected to last up to 30 refills, and a single pod will last about 120ml of e-liquid before it should be changed.
Product Spotlight: The OXVA NeXLIM Series & UNITECH 3.0 Flavor Technology
OXVA’s practical solution for the UNITECH 3.0 dual mesh tech is the NeXLIM Series of three devices all crafted to suit various vaping priorities. But, from top to bottom, they come with different coil resistances—catering to both mouth-to-lung (MTL) and restricted direct-to-lung (RDL) styles—along with BOOST and ECO Mode that carry over the entire range.
OXVA NeXLIM 2 — The Flagship Dual-Mesh Pod
The NeXLIM 2 has been designed to take full advantage of BOOST Mode. With its 2000mAh battery and 5V/3A fast charging, it delivers the power needed for simultaneous dualmesh firing, so you don’t need to make the sacrifice of decreased flavor for longer battery life. The battery level, wattage and mode are always on view with a 0.85” HD color display with switchable on-screen themes. The NeXLIM 2 is the device designed to take full advantage of dual mesh’s flavor potential when paired with the 4mL UNITECH 3.0 cartridge.
OXVA NeXLIM 2 Mini — Pocketable DualMesh Craftsmanship
The NeXLIM 2 Mini employs the same dual mesh cartridge, but in a smaller, more streamlined aluminum alloy chassis boasting a touchless, touch-driven interface. The 1500mAh battery is designed to support the device’s smaller footprint, not continuous application of BOOST, so ECO Mode is a logical match for those who wish to enjoy an alternating-coil mode but don’t want to end up with a bigger rig in their hands.
OXVA NeXLIM GO — Long-Lasting, Everyday Dual-Mesh Performance
The NeXLIM GO adds dual mesh for a more affordable and lighter device. The 1800mAh battery and PC-based construction are designed to fit the requirements of ECO Mode as intended for everyday use – rotating the two coils to maximize coil longevity, while allowing the vaper the convenient power boost of BOOST Mode on demand.
OXVA NeXLIM 2 Reviews: Recognized by Independent Vape Experts
Several independent vape review sites have recognized the NeXLIM 2’s dual-mesh capability:
-
Ecigclick picked the NeXLIM 2 for its Best Pod Mods roundup, praising its solid battery life and standout flavor.
-
VersedVaper listed the NeXLIM 2 in its Best Pod Vapes comprehensive list, citing its dual-mesh functionality and HD interface.
-
VapingVibe also called the NeXLIM 2 its best pod vape, with its UNITECH 3.0 dual-mesh flavor and dense cloud production when vaping at higher wattage.
Verdict: Is Dual Mesh the Best Flavor Vape Pod?
Single mesh coils are a fine and reliable option for simplicity and low maintenance, and are a great starting point for vapers that don’t want to adjust for different modes. For those who favor more depth and layers of flavor, the ability to select maximum intensity or coil longevity, and a longer lasting vape pod system, dual mesh coils are the more appropriate choice for vapers. Combined with the ability to switch to a higher power mod or a disposable, the BOOST and ECO mode structure is the reason this flexibility is possible in a refillable pod, but not a high-powered, disposable vape.The BOOST and ECO mode structure make that flexibility practical in a refillable pod, but not just a high-powered disposable vape, and that’s why the NeXLIM Series is a strong contender for the best flavor vape pod on the market today.
