MAXRAY RUSH 80K Hands-On Review: Big Capacity, Zero Cartridge Setup

High-puff disposables have developed a strange habit: some of them arrive feeling more like miniature kits. Open the box, unpack the device, line up a separate liquid container or cartridge, push everything together, and only then are you ready.

After using NEXA Ultra-style products that ask me to install the separate reservoir myself, the MAXRAY RUSH felt refreshingly simple. I opened the sealed bag, removed the protective pieces, and the device was already assembled.

That sounds like a tiny difference. In daily use, it is exactly the kind of quality-of-life upgrade I notice.

What Is the MAXRAY RUSH? 🔍

The RUSH is MAXRAY’s rechargeable disposable with a large transparent reservoir attached directly to the body. It looks a little like two devices fused together: a rounded screen section on one side and a crystal-clear 25mL tank on the other.

According to MAXRAY’s official product page, the main specifications are:

One important reality check: MAXRAY says its puff figures are laboratory estimates and that actual totals vary. So I would treat “80K” as the ceiling of the Normal-mode claim, not a guaranteed personal result. Draw length, mode choice and vaping habits will all change the outcome.

The Best Feature Is What You Do Not Have to Do 🧩

The biggest win here is not the screen or even the giant puff number. It is the lack of assembly.

The official NEXA Ultra package description lists a device with a 5mL integrated prefilled pod plus a separate 15mL e-liquid container. That design has its own logic, but it also gives the user another component to unpack and fit correctly.

With the MAXRAY RUSH sample, the tank and device came together as one complete unit. There was no cartridge orientation to study and no moment of wondering whether I had pushed it in far enough. Remove the protective seals, and it is ready as a single piece.

For experienced users, installing a cartridge is hardly difficult. But convenience is often about removing small points of friction. MAXRAY does that well.

The Clear Tank Is More Useful Than the Big Number 👀

The transparent tank takes up a large part of the body, and I like that. Instead of trusting a vague liquid icon, you can look directly at the reservoir and see what remains.

This is especially useful on a high-capacity product. A device claiming tens of thousands of puffs should not make you guess whether the liquid is nearly finished. Here, the liquid, central chimney and lower feed area are all visible.

The trade-off is size. The RUSH is pocketable, but it is still a chunky, rounded device rather than a slim disposable stick. That feels reasonable for 25mL and a 900mAh battery, although users who value minimal weight may find it a little substantial.

Juicy Guard Sounds Clever, but Time Will Prove It 🛡️

MAXRAY calls its liquid-control system “Juicy Guard.” The company describes it as an automatic guard intended to reduce leaks, preserve fresher hits and help the liquid last longer. The packaging also explains that a click may be heard when the guard activates during a puff.

My sample came out of its sealed bag clean around the mouthpiece and body, which is a good first impression. Still, I would not turn one clean unboxing into a long-term leak-proof verdict. The mechanism needs extended carrying, charging and daily-use testing before that claim can be judged properly.

I do appreciate that the packaging explains the click. Without that note, a mechanical sound inside a new disposable could easily make someone think something was loose.

Two Modes, a Real Screen and Useful Airflow ⚙️

The front display gives the RUSH a little visual personality, but it also shows information that matters: battery percentage and whether the device is in Normal or Turbo mode. The supplied unit showed 99% and “NORM” clearly on the screen.

Normal mode is the longevity setting and carries the up-to-80,000-puff claim. Turbo is positioned as the stronger experience and lowers the claimed total to 50,000. That lower rating is a clear trade-off: Turbo prioritizes intensity over endurance, so anyone focused on maximum life will want to stay in Normal most of the time.

There is also an airflow slider beside the intake holes and a USB-C charging port at the base. These are small, practical touches. The screen tells you when to charge, the clear tank tells you when the liquid is low, and the airflow control lets you tune the draw instead of accepting one fixed setting.

What MAXRAY has not published clearly is the coil resistance, detailed coil construction or charging rate. Those details should be added to the official specification sheet. An 80K-class device deserves more than a headline number.

Twelve Flavors, Five in This First Look 🍓

MAXRAY lists 12 RUSH flavors: Banana Taffy Freeze, Blue Razz Ice, Blueberry Watermelon, Cool Mint, Fucking FAB, Frozen Pina Colada, Juicy Grape, Juicy Peach Ice, Miami Mint, Sour Gush, Strawberry Kiwi and Strawberry Burst.

The five boxes in my unboxing were Fucking FAB, Frozen Pina Colada, Miami Mint, Juicy Peach Ice and Strawberry Kiwi. I am keeping this review focused on the hardware and setup rather than inventing a flavor ranking from an unboxing. Those profiles deserve a separate taste test after enough time with each one.

What I Like, and What Still Needs Proving ✅

What I like:

• The device arrives assembled, with no separate cartridge installation.
• The large transparent tank makes the remaining liquid genuinely visible.
• The screen presents battery percentage and power mode clearly.
• Normal and Turbo modes give a simple choice between longevity and intensity.
• Adjustable airflow and USB-C charging make it practical for daily use.

What I would question:

• The 80,000-puff figure is a manufacturer estimate, not a guaranteed real-world total.
• Juicy Guard looks promising, but leak resistance needs longer testing.
• MAXRAY should publish coil and charging specifications more completely.
• The all-in-one convenience also means the entire device becomes electronic waste when the liquid or coil reaches the end of its life.
• The official 50mg/mL nicotine strength is high and intended only for adults who already use nicotine.

The Verdict: MAXRAY Wins the Setup Test 🏁

The MAXRAY RUSH does not reinvent the high-capacity disposable. It uses the familiar formula of a visible tank, rechargeable battery, screen and two output modes. What it does better is make that formula feel immediate.

Compared with the NEXA Ultra-style setup I have used, I prefer the RUSH’s convenience. There is no separate cartridge or reservoir for me to install. I take it out, remove the protective pieces, and the hardware is ready. Simple.

The visible 25mL tank is the other major strength because it replaces guesswork with something you can check at a glance. The 900mAh battery, USB-C port, adjustable airflow and readable screen complete a sensible package.

My reservation is the same one I have with every enormous puff claim: only long-term use can show how close the device comes to the number on the box. MAXRAY is at least honest enough to label that number an estimate.

If your priority is maximum convenience and you dislike installing a separate cartridge, the MAXRAY RUSH is the easier design. If modularity matters more, a pod-style alternative may still make sense. But if your idea of convenience is “open, remove the seals and go,” the RUSH gets the important part right.

Nicotine is addictive. This product is intended only for adults who already use nicotine and is not for minors or non-users.

MAXRAY RUSH FAQ ❓

Does the MAXRAY RUSH require cartridge installation?

No separate cartridge was required with the supplied RUSH. The tank and device arrived assembled as one unit; only the protective packaging and seals needed to be removed.

Is the MAXRAY RUSH rechargeable?

Yes. It has a 900mAh rechargeable battery and a USB-C charging port.

Does it really deliver 80,000 puffs?

MAXRAY rates it for up to 80,000 puffs in Normal mode and up to 50,000 in Turbo mode, but the company identifies puff count as a laboratory estimate. Actual results vary with draw length, mode and personal use.

Can you see how much e-liquid is left?

Yes. The 25mL reservoir is transparent, so the remaining liquid can be checked directly rather than inferred only from a screen icon.
