This Viho TRX 50K review starts with the maker's numbers. The maker rates it at up to 50,000 puffs in Normal mode and up to 30,000 in Boost mode, per its TRX page. That page also lists a 1500mAh battery, a dual mesh coil, adjustable airflow and an intelligent display.
Below we cover what those specs mean and what the maker doesn't say. Adults 21+ only.
Our short verdict: it suits you if you want a long-rated device with a mode switch and airflow control. It falls short on one detail, because neither the maker's pages nor our product specs give a charge time.
Key Takeaways
- Rated up to 50,000 puffs in Normal mode and 30,000 in Boost mode, per the maker.
- Boost's rating is 20,000 puffs, or 40%, lower than Normal's.
- Other maker specs: a 1500mAh battery, a dual mesh coil, adjustable airflow and an intelligent display.
- Our product specs list 20mL of pre-filled e-liquid and 5% (50mg) salt nicotine. The maker's pages we read on 2026-10-21 state neither, and no source gives a charge time.
- It isn't on the FDA's list of 48 authorized e-cigarettes, which was current as of 08/28/2026.
TRX 50K specs at a glance
This table lists only what the maker's TRX page states. A second table below adds what our own product specs say.
| Spec | What the maker states |
|---|---|
| Puff rating, Normal mode | Up to 50,000 |
| Puff rating, Boost mode | Up to 30,000 |
| Battery | 1500mAh |
| Coil | Dual mesh coil with an advanced chip |
| Airflow | Adjustable |
| Controls | Vape mode switching and an intelligent display |
Puff ratings are the maker's estimates, not a promise. Real counts vary with draw length, mode and airflow setting.
What our product specs add
These details come from the spec sheet we hold for the TRX 50K, not from the maker's website. They match the maker on puff ratings, battery and coil.
| Spec | What our product specs state |
|---|---|
| E-liquid | 20mL, pre-filled |
| Nicotine | 5% (50mg) salt nicotine |
| Screen | 3-sided interactive screen showing e-liquid and battery levels |
| Airflow | Adjustable, with loose, tight and close settings |
| Operation | Disposable and draw-activated, no maintenance required |
Normal mode, Boost mode and airflow
The maker shows two ratings side by side: 50K for Normal and 30K for Boost. Boost is 20,000 puffs lower, which is 40% fewer.
What Boost changes isn't explained. The lower rating suggests it uses more of the device per puff, but that's our reading, not a maker statement.
So treat Normal as the long-run setting and Boost as the one you pick on purpose. If you stay in Boost the whole time, plan around 30,000 puffs, not 50,000.
The maker lists adjustable airflow but doesn't show how it's adjusted. Our product specs list loose, tight and close settings. Check the device when it arrives. Airflow control changes how much air mixes with the vapor on each draw. A tighter setting gives a more restricted pull, and a looser one gives an airier pull. Try a setting for a few draws before you judge the flavor.
Battery, coil and charging
The maker's brand story page calls the TRX 50K battery a 1500mAh rechargeable battery. Milliamp-hours measure stored charge, so a bigger number means more capacity. Your runtime still depends on the mode you use.
The maker describes a dual mesh coil with an advanced chip, and says they deliver bold, consistent Viho flavors. That's a marketing claim, and we haven't measured it. If another listing, including a retailer's, gives a different coil count, go with the maker's page.
The maker's pages don't state the charge port or the charge time. We read its home, brand story, TRX, Supercharge Pro, Turbo and Shadow pages on 2026-10-21 and found neither, and our product specs don't list them either. We won't guess. Check the device, or ask us, before you buy.
Flavors and what buyers pick
The maker shows eight editions of the TRX 50K, from First Wave to the Slush Edition, and its home page lists the Slush Series as a best seller. We haven't matched those editions to our flavor names. Our Viho TRX 50K flavors guide covers the flavors we carry.
In our own orders over the 90 days to 2026-10-21, about 1 in 5 Viho units was Strawberry Banana. Cool Mint and Sour Straws came next, at roughly 1 in 10 each. Stock changes daily, so check the Viho TRX 50K product page for what's available.
What the maker doesn't say
A review should say where the facts stop. These are the gaps:
- Tank size: not stated by the maker (our product specs say 20mL).
- Nicotine strength: not stated by the maker (our product specs say 5%, 50mg).
- Charge port and charge time: not stated by either source.
- What Boost changes: not described.
- Where it's made: not stated. See who makes Viho vapes.
- Box contents: not stated.
Not finding a fact on those pages doesn't prove it doesn't exist. It means we can't source it. The packaging is the final word on strength, so read it when your order arrives.

Viho TRX 50K review verdict
Who it fits
- You want a long-rated device and don't mind checking the details first.
- You like switching modes and setting your own airflow.
- You want a wide choice of flavors, which our guide lists.
Who should skip it
Skip it if you need a stated charge time before you buy. Skip it too if you want a device with FDA authorization.

Our FDA status guide explains what that means, and our vape laws by state guide covers where you live.
Our call
After this Viho TRX 50K review, we'd recommend it to adults who want a long-rated device with mode and airflow control. The maker backs up the headline specs on its own page, and our product specs fill in the tank size and nicotine strength. No source gives a charge time, so confirm that before you order.

Viho TRX 50K review FAQ
How many puffs does the Viho TRX 50K have?
The maker rates the Viho TRX 50K at up to 50,000 puffs in Normal mode and up to 30,000 in Boost mode. Those are estimates, and real counts vary with how you use it.
What does Boost mode do on the Viho TRX 50K?
The maker lists Boost mode with a 30,000-puff rating against 50,000 for Normal mode, and doesn't say what else it changes. The lower rating suggests Boost uses more per puff, but that's our reading, not a maker statement.
Does the Viho TRX 50K have adjustable airflow?
Yes. The maker lists adjustable airflow, vape mode switching and an intelligent display on its TRX 50K page. It doesn't describe how the airflow is adjusted.
How big is the Viho TRX 50K battery?
The maker lists a 1500mAh battery and calls it rechargeable on its brand story page. It doesn't state the charge port or the charge time, and our product specs don't either, so we don't quote one.
Does the Viho TRX 50K have FDA authorization?
No. The FDA's list of authorized e-cigarettes names 48 products from five companies, current as of 08/28/2026, and no Viho product is on it. The FDA says those are the only e-cigarettes that may be lawfully sold in the United States. What you can buy depends on your state, so check the rules where you live.
How long does a Viho TRX 50K last?
The maker gives a puff rating, not a length of time. At up to 50,000 puffs in Normal mode, how long it lasts depends on how often you use it and which mode you pick. Our guide to how long disposable vapes last explains how to estimate.
How much e-liquid and nicotine does the Viho TRX 50K have?
Our product specs list 20mL of pre-filled e-liquid with 5% (50mg) salt nicotine. The maker's pages don't state either figure, so check the packaging when your order arrives.
This product contains nicotine. Nicotine is an addictive chemical. You must be 21+ to purchase.
