Innokin Go S Review

The Innokin GO S 13W MTL Pen Starter Kit is a budget, pen-style mouth-to-lung setup built around a constant 13W output and a simple refillable 2 mL tank with an integrated 1.6Ω coil, usually showing up on sale around $12.99. It’s strongest as a low-fuss “grab it and go” option with solid MTL flavor, and weakest when you want modern charging, bigger capacity, or coil swaps.

Product Overview

Final Verdict

The GO S is a very straightforward MTL pen that hits its best notes when you keep expectations realistic: it’s a constant-output, button-fired device that prioritizes convenience and low cost over flexibility. The flavor is legitimately good for a simple integrated-coil tank, but the trade-off is living with a disposable tank/coil and older micro-USB charging.

• Who It’s For
  • Adults who want a simple MTL pen with minimal settings
  • People who prefer tighter draws and a steadier, lower-watt vape
  • Budget-focused users who don’t mind replacing the whole tank
• Who It’s Not For
  • Direct-lung users who want high airflow and higher wattage
  • Anyone who hates micro-USB or wants fast, modern charging
  • Tinkerers who want replaceable coils or bigger e-liquid capacity

How We Tested

We ran the GO S through daily carry, desk sessions, and longer “stress” chains to score Flavor, Throat Hit, Vapor Production, Airflow/Draw, Battery Life, Leak Resistance, Build Quality, Ease of Use, and Portability. We tracked refill behavior (slide-top seal, fill speed, gurgle risk), condensation at the mouthpiece, and consistency across multiple tanks. Nicotine products are for adults only; use isn’t recommended for minors, pregnant people, or people who don’t use nicotine, and our experience notes are subjective rather than medical advice.

Our Testing Experience

I started the week treating it like a “commute pen”: fill to just under the 2 mL line, click the top shut, wait a few minutes, and take short MTL pulls at my usual pace. The first thing I noticed is how steady the output feels—no ramping, no menu, just the same 13W every time. With a 50/50-style salt liquid, the draw landed slightly warm and clean; the in-mouth feel was soft on the front of the tongue, with a tidy “edge” on the exhale that didn’t spike into harshness unless I chain-pulled.

Marcus tried to bully it like a higher-output device—longer pulls, faster cadence—and that’s where the GO S shows its ceiling: vapor stays modest, and you can coax a little congestion/gurgle if you refill too fast and immediately hammer it. Jamal’s on-the-move testing was the opposite: short pulls while walking, pocket carry, quick top-offs. For him, the pen format and the simple fire button were exactly the point.

Our measured charge time from a low-battery cutoff back to full averaged about 65–70 minutes on a basic wall adapter, and my moderate-use battery typically carried me through roughly a day and a half before I felt the need to plug in.

• What we liked
  • Steady, predictable output that makes the vape feel consistent
  • Surprisingly crisp MTL flavor for an integrated-coil tank
  • Pocket-friendly pen shape that disappears in daily carry
• Who it is best for
  • Adults who want an “old-school simple” MTL kit with a button
  • Nic-salt MTL users who prioritize draw feel over big clouds
  • People who want a low-maintenance backup device
• Where it falls short
  • Disposable tank/coil means replacements cost more long-term
  • Micro-USB feels dated, and charging isn’t “quick” by 2026 standards
  • Limited headroom for heavier, high-frequency users

Review Score

How to Choose the Innokin GO S 13W MTL Pen Starter Kit?

Pick the GO S if you want a no-menu, button-fired MTL pen and you’re fine replacing the entire tank when the coil fades. It’s best for adults who prefer tighter draws, modest vapor, and a consistent low-watt experience over features. Skip it if you demand USB-C, bigger capacity, or adjustable power.

For a more modern “daily driver” MTL pod with Type-C charging and broader pod options, look at the Vaporesso XROS 4 (1000mAh, Type-C 2A, 3 ml/2 ml pod options). For a compact step-up with a display and multiple integrated-coil pod options, the Uwell Caliburn G3 is a strong alternative.

Limitations

The GO S succeeds by being simple, but that simplicity is also the constraint.

• Disposable tank/coil design increases waste and replacement dependence
• Micro-USB charging and slower top-offs compared with modern Type-C devices
• Limited power and capacity make it less satisfying for heavy users and longer sessions

Innokin GO S 13W MTL Pen Starter Kit vs. Alternatives

• Why choose these models
  • GO S: constant 13W, simple one-button MTL, very low cost of entry
  • Works well with MTL-focused e-liquids and quick daily carry routines
  • Adjustable airflow helps tune the draw without learning settings
• Alternatives to consider
  • Vaporesso XROS 4: Type-C 2A charging, more modern feature set, broader pod compatibility
  • Uwell Caliburn G3: higher max output with multiple pod resistances, display, Type-C
  • If you want bigger liquid capacity and higher output, move to an RDL-capable pod platform instead of a pen kit

Pro Tips for Innokin GO S 13W MTL Pen Starter Kit

• Fill slightly below the top of the 2 mL chamber to reduce pressure flooding after closing.
• After filling, give it a few minutes before the first session so the integrated coil fully saturates.
• If you hear gurgling, pause for a minute and take a few lighter pulls; rushing it usually makes spitback worse.
• Keep the airflow a touch more open than you think you need; it often smooths the draw and reduces condensation.
• Use thinner, MTL-friendly blends (higher-PG or 50/50-style) to help wicking keep up at 13W.
• Wipe the mouthpiece and top cap regularly; pen kits collect condensation faster than you expect.
• Treat tanks as consumables: once flavor dulls or the draw tightens permanently, swap the entire tank rather than forcing it.
• Don’t store it full in a hot car; heat expands liquid and can push it into the coil chamber.
• Charge before it’s completely dead if you’re relying on it all day; micro-USB top-offs are slower than modern Type-C.
• Carry a spare tank if this is your only device—when the integrated coil goes, you can’t just swap a coil head.

FAQs

Is the GO S draw-activated?

No. In our use it’s a simple one-button pen: you press to fire, and that’s basically the whole interface.

Can you replace the coil in the GO S tank?

No—the coil is integrated, so when performance drops, you replace the whole GO S tank.

Why does it sometimes gurgle after refilling?

Usually it’s refill technique: overfilling, closing the slide-top too quickly, or vaping immediately can push liquid into the coil chamber.

Is it better for nic salts or freebase?

It’s primarily an MTL kit; we found it most consistent with MTL-style liquids and shorter, lighter pulls rather than long, high-output sessions.
