OXVA VPrime | which e-liquid for each pod

On the OXVA VPrime product page, e-liquid gets a single line, nic salts and freebase both accepted. Yet the device runs anywhere from 12 to 60 W depending on the pod fitted, and the same bottle behaves very differently in a 0.2 ohm coil and in a 0.8 ohm one. Too thick, it starves the wick. Too thin, it seeps towards the airflow. OXVA has published far more precise pointers elsewhere.

OXVA VPrime, the right e-liquid depends on the pod

For the OXVA VPrime, the usage guide published by OXVA sets two ratios. A freebase nicotine liquid should be 30/70, meaning 30% propylene glycol (PG) to 70% vegetable glycerine (VG). A nic salt liquid should be 50/50.

Nicotine strength then follows the coil. It stays low on the 0.2 ohm pod, run between 45 and 60 W, and can climb on the 0.8 ohm pod, which works between 12 and 18 W.

The same logic applies to most powerful pod kits. The lower the resistance, the higher the wattage and the vapour volume, and the harsher a strong liquid generally feels on the throat. Choosing the bottle after the pod, not the other way round, avoids most disappointments.

Four OXVA VPrime pods, four liquids

The kit ships with two pods, 0.2 and 0.6 ohm, but OXVA lists four compatible values. For each one, its guide gives a wattage range, a maximum nicotine strength and a ratio, summarised below.

VPrime pod	Suggested wattage	Freebase at 30/70	Nic salts at 50/50
0.2 ohm	45 to 60 W	0 to 3 mg/ml	0 to 6 mg/ml
0.4 ohm	28 to 35 W	0 to 6 mg/ml	0 to 10 mg/ml
0.6 ohm	20 to 25 W	0 to 9 mg/ml	0 to 20 mg/ml
0.8 ohm	12 to 18 W	0 to 12 mg/ml	0 to 20 mg/ml

One line of the guide needs correcting for British readers. For the 0.8 ohm pod, OXVA quotes nic salts up to 30 mg, a strength you will not find on UK shelves. The Tobacco and Related Products Regulations 2016 cap nicotine e-liquid at 20 mg/ml, sold in bottles of no more than 10 ml, and the table follows that limit.

VPrime coil at 0.2 or 0.4 ohm, a low-strength liquid

The 0.2 ohm pod, fitted in the kit, is the direct-lung option, with the airflow fully open. It vaporises a lot of liquid with every puff, hence a ceiling of 3 mg/ml for freebase.

The 0.4 ohm pod, sold separately, runs between 28 and 35 W with the airflow three-quarters open. It takes a slightly higher strength, 6 mg/ml in freebase or 10 mg/ml in nic salts.

VPrime coil at 0.6 or 0.8 ohm, higher strengths allowed

The 0.6 ohm pod, the second one in the box, targets a restricted direct-lung draw, with the airflow half open. It is the first in the range to take nic salts right up to the 20 mg/ml legal ceiling.

The 0.8 ohm pod, the tightest, is the only one that drops below 20 W, with the airflow barely open. Its draw comes closer to an entry-level pod, and a nic salt liquid fits it naturally.

Nic salts or freebase in an OXVA VPrime

Both types work in every pod, as the manufacturer’s spec sheet states. The difference lies in strength, and the gap is far from trivial.

For the same pod, OXVA allows nic salts at twice the freebase strength on the 0.2 ohm, and more than twice on the 0.6 ohm. Nic salts generally feel smoother on the throat at the same strength, which explains that gap.

In practice, a nic salt vaper will lean towards the 0.6 or 0.8 ohm pod, where those strengths make sense. On the 0.2 ohm at 60 W, a 20 mg/ml salt sits far above the 6 mg/ml ceiling set by the manufacturer.

The ratio follows the same split, 30/70 for freebase, 50/50 for salts. Our guide to choosing e-liquid by ratio and strength explains what each blend changes in the vapour.

PG/VG ratio and leaks on the OXVA VPrime

A liquid that does not suit the pod does more than vape poorly. It can also leak, and OXVA’s online help, written for its whole pod range, sets out why.

There, OXVA recommends a 50/50 ratio to limit leaks, and points out that a wattage too low for the coil leaves liquid unvaporised, which ends up seeping out. A pod filled and then left unused for more than three days is also more likely to leak.

The two pieces of advice only clash on the surface. The 30/70 in the guide assumes a pod run within its range. If a pod leaks with a 30/70 at the bottom of its range, raising the wattage by a few watts or going back to 50/50 are the two fixes to try.

That leaves the contact area between pod and device, which should be wiped and dried before the pod goes back in. A leak that persists after all this usually points to the pod itself, which needs replacing.

Filling an OXVA VPrime pod without flooding the wick

The pod fills from the top, under a silicone tab. How you pour matters as much as the bottle you pick, especially with a new pod.

The OXVA VPrime manual asks you to wait 5 to 8 minutes after filling a new pod, so the cotton can soak. OXVA’s general help mentions 3 minutes for its other pods, but the VPrime’s own instruction, the longer one, is the one to follow here.

When pouring, slide the bottle nozzle in without touching the inner structure of the pod, and avoid squeezing the bottle again and again. Then close the tab straight away. OXVA reckons that if it stays open for more than 30 seconds, the liquid may leak.

Capacity depends on the version. The standard pod holds 5 ml, but UK rules cap refillable tanks for nicotine e-liquid at 2 ml, so the 2 ml TPD pod is the one sold in Britain.

Sweet liquids and a 2 ml pod

VPrime coils cannot be changed, except on the empty pod sold separately. The liquid you choose therefore also sets how quickly pods wear out.

A very sweet recipe generally gunks up a coil faster, especially at high wattage. OXVA advises replacing the pod as soon as a burnt taste appears or the vapour drops noticeably, and cleaning it once a week to stop residue building up.

With only 2 ml, a 0.2 ohm pod at 60 W also empties faster than a 0.8 ohm pod at 15 W. A less sweet liquid therefore spares the coil over time. Our guide on when to change a vape coil lists the signs worth trusting.

FAQ

These questions cover the bottle itself and moving a pod from one liquid to the next.

How many refills does a 10 ml bottle give?

A 10 ml bottle gives five full refills of a 2 ml TPD pod. Take off the few drops placed on the cotton of a new pod.

Can you switch flavours in the same pod?

You can, but the cotton holds on to part of the previous flavour for several refills. Pods come in packs of two, which makes it easy to keep one per flavour.

Does a 100% VG liquid suit the OXVA VPrime?

OXVA does not go above 70% vegetable glycerine in its recommendations. A thicker liquid generally feeds the cotton more slowly, with a risk of dry hits at high wattage.

Does the empty pod take the same liquids?

Yes, OXVA lists it as compatible with nic salts and freebase. Its 0.4 and 0.6 ohm replacement coils follow the matching rows of the table.

Does the VPrime 2 change the choice of liquid?

Its Dual Mesh pod, in 0.4 or 0.6 ohm, takes the same two types of liquid, and the VPrime 2 also accepts the original model’s pods. OXVA has not, however, published a strength table specific to the VPrime 2.

OXVA VPrime, picking the bottle after the pod

Choosing liquid for an OXVA VPrime is a two-step job. The pod sets the wattage and the maximum nicotine strength first, then the nicotine type sets the ratio, 30/70 for freebase or 50/50 for salts, never above 20 mg/ml.

A well-soaked wick, a tab closed quickly and a wattage within the pod’s range do the rest. Matching the bottle to the coil rather than to the device is a habit that holds for any pod kit, and the OXVA VPrime is a clear example of why.
