OXVA Xlim Pro 2 DNA Review: Evolv Chip Tested

Specs

[THREE_IMAGE_SHORTCODE]

What the DNA Chip Actually Does

Standard pod kit chips fire at a set wattage. The Evolv DNA chip inside the Pro 2 DNA makes 30,000 micro-adjustments per second. It reads coil resistance, temperature, and battery voltage in real time and adjusts power on the fly.

In practice, three things come from this:

1. Better battery efficiency - the chip only sends the power the coil needs at that exact moment, not a fixed amount
2. Replay mode - locks in a specific puff profile and recreates it every time
3. Temperature control - sets a ceiling so the coil can't overheat, killing dry hits before they happen

You don't need to understand any of that to use the kit. It works out of the box with the settings OXVA dialled in. But if you want to know why the battery lasts longer and the flavour stays more consistent, that's the answer.

Battery Life

Same 1300mAh battery as the standard Pro 2. Different results.

I ran both kits side by side for a week. Same pods, same 10mg dessert nic salt, same vaping pattern. The standard Pro 2 got me through the day. The DNA version pushed four hours past that, well into the next morning.

That's not a bigger battery. It's a better chip. The DNA doesn't waste power overshooting or undershooting wattage like a standard chip does. It sends exactly what the coil needs and nothing more.

For heavy use at around 400 puffs a day, I'm getting a day and a half per charge. USB-C charging takes about 45 minutes from flat to full, with a faster charge up to 80% then a slower taper to protect the cell.

Replay Mode

Take a puff you like right warmth, right flavour intensity, right throat hit. Press the button to save it. From that point, every puff tries to match those exact conditions.

From that saved puff, the DNA chip remembers the power curve, coil temperature, and resistance profile. It adjusts in real time to recreate it regardless of battery level or coil age.

I've been using replay mode on a 0.6 ohm SS pod with 10mg vanilla custard nic salt. Puff one tastes like puff one hundred. The consistency is the single biggest difference between the DNA and standard Pro 2. On a normal chip, flavour drifts as the battery drops or the coil ages. Replay mode compensates for both.

Not every vaper will care about this. If you just want to fill and go, you won't miss it. But once you've used it, you notice the inconsistency on kits without it.

Temperature Control

Stainless steel pods open up temperature control. Set a maximum temperature and the coil won't go past it. When e-liquid runs low, instead of a burnt hit, the kit dials back power on its own.

I tested this by vaping a pod almost dry on purpose. No burnt taste. Flavour faded gradually and the hit got lighter, but nothing unpleasant. On a standard chip, that same pod would've tasted like charcoal.

Temperature control only works with the SS (stainless steel) pods. Kanthal pods from the standard V2 and V3 range still work in the kit but fire in standard wattage mode only.

Pro 2 DNA vs Standard Pro 2

This is the comparison most people are searching for.

Same body. Same pods. Same airflow. The DNA chip is the only physical difference. It changes battery life, adds replay mode and temp control, and opens up Escribe software customisation.

If your standard Pro 2 does everything you need and you're happy with the battery, there's no urgent reason to swap. If you want longer battery life, replay consistency, or dry hit protection, the DNA version is the upgrade.

Escribe Software and Themes

Plug the Pro 2 DNA into your PC via USB-C and Escribe opens up full customisation. Power curves, screen themes, wallpapers, temperature profiles, and display layout.

Most people won't touch this. Out of the box settings work well. You can dial in a custom power curve for a specific e-liquid. Set different profiles for MTL and RDL pods. Escribe handles all of it.

Themes and wallpapers can be changed through Escribe too. You can upload custom backgrounds or pick from existing options. A few people are searching for "oxva dna theme" and this is where you change it - not on the kit itself, through the PC software.

Storage Mode

If you're not using the kit for a while, Escribe has a storage mode that drops the battery to a safe level for long-term storage. Keeps the cell healthy if you're shelving it between uses.

Fill Pod Error

Some users are seeing a "fill pod" error on screen. This happens when the kit detects the pod isn't seated properly or the contacts aren't connecting.

Pull the pod out. Check the bottom contacts for e-liquid residue. Wipe clean with a tissue. Reseat the pod firmly until it clicks. If the error keeps showing, try a different pod - a faulty contact on the pod itself can trigger it.

Pod Compatibility

Every Xlim pod works in the Pro 2 DNA. V2 side-fill, V3 top-fill, EZ 3ml, and the new SS stainless steel pods. No need to buy special pods for the DNA version.

For temperature control and replay mode, use the SS pods. They're the only ones that support those features. Kanthal pods (V2, V3, EZ) work fine for standard wattage vaping but can't do temp control. Browse the Xlim range for the full range of resistance options.

Colours

Several colour finishes are available for the Pro 2 DNA:

• Forged Carbon (the one I've been testing)
• Black Leather
• Brown Leather
• Gunmetal Wood
• Arctic Ice

Forged carbon is the one to get. The pattern shifts depending on the light. Under indoor lighting it looks dark with subtle texture. In direct sunlight the weave shows through more. After weeks of pocket carry, mine still looks fresh with no visible wear.

Build and Design

Same dimensions as the standard Pro 2. Fits the same in a pocket. Same button placement, same weight. If you've held any kit in the OXVA range, the DNA version feels familiar in hand.

The screen is the same 0.56 inch colour display. Shows wattage, coil resistance, battery percentage, and current mode. Readable in sunlight. Three clicks for mode cycling, five clicks to lock.

Magnetic pod connection holds firm. No rattling, no accidental pops. The airflow slider on the side adjusts from tight MTL to open RDL with clear steps between settings.
