Best E-Liquids for OXVA UNIONE
The UNIONE holds 10ml of e-liquid — five times a standard pod kit. Its dual-chamber design (2ml active + 8ml reserve) changes how you should think about buying and using liquid. This guide covers what works best and how to get the most from the unique 10ml system.
UNIONE Liquid Compatibility
| Liquid Type | Compatible? | Best Strength | Notes |
|---|---|---|---|
| 50/50 Nic Salt (10ml) | Best choice | 10–20mg | Thin formula, ideal for 0.8Ω coil |
| High-VG Nic Salt | Good | 10mg | Works well, slightly slower absorption |
| Freebase 50/50 | Good | 3–6mg | Good for lower-nic users |
| Shortfill 70VG+ | OK in Eco only | 0–3mg | Avoid in Boost mode |
| Sweetener-heavy juices | Avoid | Any | 10ml x sweetener = rapid coil degradation over 7+ days |
The 10ml Advantage — Using It Smartly
Because the UNIONE takes a full 10ml bottle, you can plan your liquid rotation differently from standard pods:
- Fill with one 10ml nic salt — Entire bottle in one go. No measuring, no partial fills. Lasts approximately one week.
- Blend two flavours — Add 5ml of one salt, 5ml of another. The 2+8 dual-chamber gives a unique combined taste profile.
- Weekly flavour rotation — Use a single flavour Monday–Friday, switch at weekends. One pod per week = 4 liquid bottles per month.

Eco vs Boost: Which Mode for Which Liquid
ECO mode (15.5W) — Slower vaporisation, lower liquid consumption per session, smooth hit. Best pairing: 20mg nic salt for satisfying delivery at reduced power.
BOOST mode (17.5W) — Stronger, brighter hit. Best pairing: 10mg nic salt. Slightly faster liquid consumption but noticeably better flavour intensity.
Flavours That Work Best in a 10ml Fill
- Fruit salts — Clean, consistent flavour throughout the 10ml fill over 7 days. Does not go stale
- Menthol salts — Freshness maintained over a full week. Popular choice for UNIONE owners
- Tobacco salts — Rich all-day flavour pairs well with UNIONE’s consistent delivery
- Cream/custard — Sweetener builds over 7+ days in a large-capacity coil. Use sparingly or rotate more frequently
