18ml Disposable Vape (A37-3) – 1.0Ω Dual Mesh Coil | Vape OEM Factory

At 18ml a disposable runs for weeks, which creates a problem smaller formats never face: the user has no idea how much is left. The A37-3 answers it on the front of the device — battery level and e-liquid level, read without turning the device over, on a cylinder body running a 1.0Ω dual mesh coil. It sits in our disposable vape category.

Why a display matters most at high capacity

The larger the reservoir, the worse the guess. On a 2ml device a user learns the rhythm in a day. On 18ml the cycle stretches past the point where anyone tracks it, so the device either gets discarded with liquid inside or runs dry without warning.

The two readings serve different purposes. Battery level tells the user when to charge. Liquid level tells them when to reorder — the commercially useful signal, because a user watching the tank drain buys the replacement before the gap rather than after it.

Panel placement decides whether the reading gets used. A front-facing panel sits in the user's line of sight during a normal draw, so the liquid level registers passively without anyone checking for it. Bottom-mounted panels require lifting the device, which most users do only once they already suspect it is running low — by which point the reading arrives too late to prevent the gap.

Among cylinder-format devices, a front panel is still uncommon. Box formats adopted displays first because a flat face gives the panel somewhere obvious to sit. Brands whose retail channel favors upright counter displays and tube racks have had to choose between the format and the feature; the A37-3 removes that trade-off.

Why a dual mesh coil at 18ml

Two coils split the work. Each runs cooler at a given output than a single coil doing the same job, and the wick surface roughly doubles. That changes the failure pattern at high capacity: single-coil devices tend to taste clean early and scorch late, because one wick carries the full thermal load for the life of the reservoir.

The 1.0Ω resistance keeps the draw in MTL range rather than sub-ohm. That pairing is deliberate here — a tighter draw consumes liquid more slowly, so 18ml lasts proportionally longer than the same volume in a sub-ohm device.

The 600mAh cell recharges over Type-C, which matters more at this capacity than at smaller ones. A non-rechargeable cell would strand liquid inside the device — the exact problem the display exists to prevent.

Each unit ships pre-filled to your specification. Nicotine strength runs 0–5% customizable, and flavor is selected from our core library, built to the standards of the destination market. Brands supplying markets that prefer user-filled hardware can look at our open-system refillable format instead.

A37-3 Frequently Asked Questions

What does the A37-3 display show, and where is it?

A front-facing panel on the lower body shows battery level and remaining e-liquid level. Front placement keeps the liquid reading visible during normal use, so the end user reorders before the device runs dry.

What is the liquid capacity of the A37-3?

18ml, pre-filled to your specification before shipment.

What does the dual mesh coil do at this capacity?

Two 1.0Ω mesh coils split the thermal load and roughly double the wick surface, which keeps flavor consistent deeper into an 18ml reservoir than a single-coil design.

How does the A37-3 compare to the A37-2?

Both are cylinder-format rechargeable disposables. The A37-3 carries 18ml with a dual mesh coil and a front-facing battery and e-liquid display in a 30 × 130.2 mm body. The A37-2 holds 12ml with a single 1.0Ω mesh coil in a shorter 30 × 110 mm body and no display.

Can the A37-3 be customized for a private-label program?

Yes. The A37-3 supports OEM/ODM customization, including nicotine strength, flavor, logo, color coating, and packaging design.
