If you're searching "NEXA vape refill," here's the short answer: you cannot refill any NEXA device with e-liquid. All NEXA vapes are closed-system — the tanks are sealed and not designed to be opened. What you can do is replace the entire pre-filled pod on the NEXA Flex series. This guide covers which NEXA devices support pod replacement, how the process works, and how to know when it's time for a new pod.
Can You Refill a NEXA Vape?
No. Here's the breakdown by device:
| Device | Refillable? | Pod Replaceable? | When It's Empty |
|---|---|---|---|
| Ultra II 50K | ❌ No | ❌ No | Replace entire device |
| PIX 35K | ❌ No | ❌ No | Replace entire device |
| Pro 30K | ❌ No | ❌ No | Replace entire device |
| Flex 35K / 40K | ❌ No | ✅ Yes | Replace the pod, keep the battery |
| InvisaCloud Edition | ❌ No | ❌ No | Replace entire device |
NEXA Flex: How Pod Replacement Works
The NEXA Flex is the only NEXA device designed for pod swapping. The system works like this:
- Buy the Flex kit — includes a 1200mAh battery unit and one pre-filled pod
- Vape until the pod is empty — check the Crystal Tank for e-liquid level
- Remove the empty pod — pull straight up; the magnetic connection releases cleanly
- Attach a new pre-filled pod — press down until it clicks magnetically into place
- Continue vaping — the battery is reusable across multiple pods
Each Flex pod delivers up to 35,000–40,000 puffs in Normal mode. The battery unit is rechargeable via USB-C and designed to last through many pod cycles. This makes the Flex the most cost-efficient NEXA device over time — you're only buying the pod, not a new battery each time.
Flex Coolness Edition
The Coolness Edition adds a 4-level adjustable cooling system to the standard Flex. The cooling dial lets you control menthol intensity independently from the flavor — a unique feature that no other NEXA device (or most competitors) offers. Pod replacement works identically to the standard Flex.
How to Tell When Your NEXA Is Empty
Unlike most disposables that leave you guessing, NEXA devices with Crystal Tank technology let you see your e-liquid level directly. Here's what to watch for:
- Crystal Tank devices (Ultra II, PIX, Flex): Look at the transparent tank section. When the visible liquid drops below the bottom graduation mark, you're in the cotton-reserve zone. The device may continue working for a while (the 4–5mL cotton storage provides a buffer), but flavor quality will gradually decline.
- Non-Crystal Tank devices (Pro 30K, InvisaCloud): Watch the screen for any low-liquid warnings. When flavor starts tasting thin, muted, or slightly burnt, the device is nearly empty.
- Universal sign: A noticeable decrease in vapor production combined with weakened flavor is the clearest indicator that any disposable is running out.

Frequently Asked Questions
Can I put my own vape juice in a NEXA?
No. All NEXA devices use sealed, pre-filled e-liquid systems. There is no fill port, and the tanks cannot be safely opened. Attempting to do so will damage the device.
Where can I buy NEXA Flex replacement pods?
NEXA Flex replacement pods are available at VapesOnlineShop. They're sold separately from the battery unit, so you only pay for the pod when you need a new one. Check the NEXA collection page for current stock and pricing.
How many pods can a NEXA Flex battery handle?
The 1200mAh Flex battery is designed for long-term reuse across many pod cycles. With proper charging and care, it should last through dozens of pod replacements before battery degradation becomes noticeable. The USB-C charging port ensures fast recharging between pods.
Is it cheaper to use the Flex pod system or buy disposables?
The Flex pod system is cheaper over time. After the initial kit purchase, each replacement pod costs less than buying a full new device. The tradeoff is that disposables like the Ultra II and PIX require zero maintenance — you just use and replace. The Flex requires charging and pod management.
