  • Who It’s Not For: ultra-light pocket carry, strict MTL-only use, and anyone who never wants to touch settings

In our actual testing, we ran the same checklist across all four devices: flavor clarity across repeat refills, throat hit consistency with common nic-salt strengths, and vapor output on both short and longer pulls. We also checked airflow smoothness, battery life in normal carry patterns, leak resistance after pocket time, and build quality after daily handling. Ease of use covered refills, coil or pod swaps, and basic day-to-day reliability. Portability came down to pocket comfort, lanyard carry, and how ready each one felt for quick grab-and-go use.

Our Testing Experience

In our testing, the original Caliburn KOKO still felt like the easiest device here to carry without thinking about it. The square body disappeared into a pocket, the draw stayed steady through short sessions, and flavor stayed cleaner than many small pod systems once the pod settled in. With a 2mL pod, a 520mAh battery, and an 11W ceiling, it clearly favors a calm MTL rhythm over bigger, warmer output.

Marcus used it with longer pulls to see where it started to flatten out. It stayed composed, but the limit showed up quickly: this is not the KOKO to reach for when you want denser vapor. Jamal liked it most as a true out-the-door device because the auto-draw routine and compact shape made it easy to carry, quick to use, and easy to put away.

• What we liked:

  • Clear flavor separation at a tight MTL pace

  • Predictable draw with almost no learning curve

  • Very compact shape for pocket carry

• Who it is best for:

  • Adults who want a simple MTL pod for commuting or short breaks

  • Users who care more about consistency than output

  • Anyone who wants a reliable secondary device

• Where it falls short:

  • The small battery feels limiting with heavier use

  • There is no real airflow or wattage tuning

  • Vapor output stays modest

Our Testing Experience

The KOKO Prime felt like the version of the original idea that gained a little range without giving up the pocket-first form. In our testing, the bigger 690mAh battery made a noticeable difference over the base KOKO, and the airflow behavior changed enough with pod orientation that the device genuinely felt more versatile instead of just slightly different. It still stays in the compact, low-output lane, but it does more inside that lane.

I used it as a work-break device because it handled uneven use well: a few quick draws, a longer pause, then another short session without feeling fussy. The 1.0Ω coil gave the tighter, more cigarette-like pull, while the 0.8Ω option added a warmer edge and a little more body. Marcus found it easier to lean on than the original KOKO, and Jamal liked that it still carried easily while feeling more complete as an only device.

• What we liked:

  • Better flexibility than the original KOKO

  • Two clearly different draw styles with a simple pod change

  • Strong flavor at modest power

• Who it is best for:

  • Adults who vape MTL most of the time but occasionally want a warmer pull

  • Users who do not mind changing coils

  • Anyone who wants a compact pod that feels more adaptable

• Where it falls short:

  • It is still not a high-power device

  • Coil swapping adds a little upkeep

  • The 2mL pod means more refills for heavier use

Pros & Cons

Details

• Device type: refillable pod system

• Pod capacity: 2mL

• Battery capacity: 690mAh

• Max output: 15W

• Coil support: 0.8Ω Meshed-H and 1.0Ω FeCrAl

• Charging: USB Type-C fast charging

Our Testing Experience

The Prime Vision kept the KOKO Prime formula familiar, but it changed the feel of the device in the hand because the translucent shell makes it read more like a style piece than a pure utility carry. In our tests, the actual vape stayed close to the Prime when we matched coil and liquid, which is what mattered most. Flavor stayed crisp, the draw options remained useful, and the device never felt like it traded performance away for appearance.

That said, the body did make us handle it a little more carefully. Marcus had no issue with heat or stability on longer pulls, but he still preferred the G3 Pro KOKO when he wanted more air and more output. Jamal liked the way it carried, especially on a lanyard, but he also pointed out that this is the version you notice scuffs on first if you are rough with your gear.

• What we liked:

  • Prime-style performance with a more distinctive shell

  • Good flavor with coil options that feel meaningfully different

  • Compact carry with a more standout look

• Who it is best for:

  • Adults who want Prime performance but care about the look of the device

  • Users who rotate devices and want one with more visual character

  • MTL-first users who sometimes move into a warmer pull

• Where it falls short:

  • The shell feels less carefree in rough daily carry

  • You still get the same 2mL refill cadence

  • It is not built for big-cloud output

Pros & Cons

Details

• Device type: refillable pod system

• Pod capacity: 2mL

• Battery capacity: 690mAh

• Max output: 18W

• Coil support: 1.0Ω pre-installed and 0.8Ω spare options

• Form factor: compact square pod kit with lanyard-friendly carry

Our Testing Experience

The G3 Pro KOKO is the point where the KOKO line stops being a simple square pod and starts feeling like a true main device. In our testing, the 1250mAh battery, the 35W ceiling, the 1.8-inch TFT display, and the G3 cartridge platform gave it the widest usable range in this group. It can still be kept compact, but it no longer behaves like a tiny, set-and-forget sidekick.

I reached for it during longer evening sessions because it responded well when I wanted to tune the vape instead of taking whatever the device gave me. Open the airflow and it produces clearly denser vapor; pull the setup back and it becomes more restrained without feeling flat. Marcus preferred it immediately for repeated pulls and higher output, while Jamal liked the battery life but said it was the least invisible in a pocket.

• What we liked:

  • Strong control over output and draw feel

  • Denser vapor with a more RDL-friendly range

  • Screen feedback makes settings easier to manage

• Who it is best for:

  • Adults who want RDL-leaning performance in a compact footprint

  • Users who like adjusting wattage and airflow

  • People who want a KOKO-format device that can serve as a main setup

• Where it falls short:

  • More controls mean more room to over-tune

  • It is larger and heavier than the classic KOKO models

  • High output drains the battery faster when pushed hard

Pros & Cons

Details

• Device type: refillable pod system

• Battery capacity: 1250mAh

• Max output: up to 35W

• Display: 1.8-inch TFT

• Pod capacity: 3mL

• Cartridge platform: G3 cartridges, including 0.4Ω in the series

The KOKO Prime is the most even performer overall: it does not dominate any one category, but it also avoids the obvious compromises of the base KOKO and the extra setup of the G3 Pro KOKO. The G3 Pro KOKO separates itself on vapor output and airflow range, while the original KOKO still wins on simplicity and pure carry comfort.

Start with the draw style you actually prefer. If you want a tight MTL pull with very few decisions, the Caliburn KOKO stays the cleanest and simplest choice. If you want MTL most days but sometimes want a warmer, slightly looser pull, the KOKO Prime is the best all-around fit, with the Prime Vision offering a similar experience in a more design-led shell. If you want adjustable wattage, a screen, and more RDL headroom, the G3 Pro KOKO is the one that makes sense. For commuting and light carry, keep size and simplicity high on the list. For longer sessions, give more weight to battery headroom and output control.

• Caliburn KOKO: small battery, limited vapor, no tuning

• Caliburn KOKO Prime: coil upkeep, frequent refills, modest power ceiling

• Caliburn KOKO Prime Vision: finish shows wear sooner, styling matters more than performance gain, same refill cadence

• Caliburn G3 Pro KOKO: bulkier carry, easier to over-tune, faster battery drain at high output

• Why choose these models:

  • Compact bodies with strong flavor focus

  • Easy daily carry in a square, pocket-friendly shape

  • Options that range from simple MTL to adjustable RDL

• Alternatives to consider:

  • Vaporesso XROS 4 Nano: smooth MTL draw and easy pod swaps

  • OXVA XLIM Pro: strong flavor with simple adjustment

  • Geekvape Sonder Q: low-fuss carry at a lower barrier to entry

• Prime any new pod or coil before the first pull to avoid a dry, harsh start

• If flavor drops off, clean the mouthpiece area and clear any condensation before assuming the coil is done

• Do not overfill the pod; leaving a small air gap helps reduce seepage

• For a tighter draw, stay with the higher-resistance setup and avoid opening airflow more than needed

• For warmer vapor, use the lower-resistance option and keep the pull controlled rather than extra long

• Charge with a decent USB-C power source and avoid treating fast charging as a reason to leave the device plugged in for hours

• If this is your all-day device, keep a spare pod or coil in your bag

• Heavily sweetened liquids will usually shorten coil life faster than lighter mixes

The original Caliburn KOKO still gives the simplest tight MTL experience. The KOKO Prime can get close while giving you more room to adjust the feel through coil choice and pod orientation.

If you only want quick MTL puffs and never touch settings, it can be more device than you need. If you like adjusting the draw and want more output headroom, it earns the extra size.

In day-to-day use, the vape feels broadly similar when the coil and liquid are matched. The biggest difference is the body: the Prime Vision leans harder into the translucent, style-first design.
