Boro AIO head to head, Centaurus G80S against Cthulhu RBA AIO 2

Two boxes of similar size, one 18650 cell each, a tank that slides into the body of the device. On paper, the boro AIO from Lost Vape and the one from Cthulhu Mods look close enough to be confused. Their spec sheets describe two devices built for different vapers, though, and one of them hides a trap in the model name itself. This review sets them against five criteria fixed in advance, the atomiser supplied, power, resistance range, airflow and capacity.

Which boro AIO to pick between the Centaurus G80S and the Cthulhu AIO 2

The answer depends on the vaper. Lost Vape’s Centaurus G80S suits someone who wants a boro AIO open to several tanks, with 80 W, a screen and a 2 ml tank version published by the manufacturer. The Cthulhu RBA AIO 2 suits someone who builds their own coils and fine-tunes the draw, with power capped at 60 W.

One warning comes first, and it hangs on a single letter. Lost Vape presents the Centaurus G80, without the S, as designed for its UB AIO pod and UB Ultra coils, and pairs it on the boro side with its own Centaurus Boro tank only. Compatibility with all boro tanks is kept for the G80S.

This review is not based on hands-on use. It sets the manufacturer’s listing for the Centaurus against two matching retailer listings for the Cthulhu.

Two boro AIO devices, five criteria side by side

The table only carries what the sources confirm. Where a cell reads “not published”, the listings either leave the figure out or disagree on it.

Criterion	Centaurus G80S (Lost Vape)	Cthulhu RBA AIO 2 (Cthulhu Mods)
Intended atomiser	Boro tanks, including the Centaurus Boro	Boro with a Tree RBA deck
Maximum power	80 W (5 to 80 W)	60 W
Battery	One 18650, not included	One 18650, not included
Resistance range	0.12 to 2 ohms	Not published consistently
Airflow	Three pins of 1, 2 and 3 mm on the Centaurus Boro	Seven pins from 1 to 3.4 mm
Published capacity	5 ml, or 2 ml in the TPD version	Not published consistently
Screen	0.42 inch OLED	Screen type differs between listings

The reading is clear. The Centaurus has the edge on power and on how precise its listing is, the Cthulhu on how finely the airflow can be tuned.

Atomiser supplied, coil pod or rebuildable deck

This first criterion shapes everything else, because it decides which consumables you will buy afterwards. The two brands went in opposite directions.

The Centaurus G80 family and its two routes

Lost Vape offers its box in two versions. The G80, sold as the two-pin version, targets the UB AIO pod, which takes UB Ultra coils of 0.15, 0.2 and 0.3 ohm, and its listing also lets it switch to the brand’s Centaurus Boro tank. The G80S, sold as the single-pin version, accepts all boro tanks according to the manufacturer, the Centaurus Boro included.

That split has a real benefit. A vaper can start with a boro AIO style device on ready-made coils with the G80, try the Centaurus Boro on the same box, and only move to the G80S to fit boro tanks from other brands. The version still has to be chosen at the checkout, not afterwards. Our notes on Lost Vape coils also apply to the UB Ultra heads in that pod.

The Cthulhu’s Tree RBA deck

The Cthulhu RBA AIO 2 comes with a rebuildable deck called the Tree RBA, designed for a single coil. No shop-bought coil is planned for in the box, so the vaper fits their own wire and cotton.

That demand has an entry cost. You need to work out the resistance of your build, and our piece on the coil calculator explains why a calculated figure never replaces a reading on an ohm meter.

Power, the 18650 cell and resistance range

Both devices share the same power source, an 18650 cell sold separately. That common ground sets a physical ceiling, since a single cell supplies all the power asked of it.

The Centaurus lists 80 W and a range of 0.12 to 2 ohms. The Cthulhu stops at 60 W according to both retailers consulted. On a rebuildable coil of middling resistance the gap matters little; it becomes noticeable with a very low mesh build that asks for more.

Charging deserves a remark. Lost Vape lists a USB-C input of 5 V at 1.85 A, but a removable cell is generally better charged in a dedicated charger, which also lets you rotate two cells.

Boro capacity and the 2 ml version

For its Centaurus Boro and for its UB AIO pod, Lost Vape publishes a capacity of 5 ml in the standard version and 2 ml in the TPD version. The manufacturer’s listing states both figures plainly.

In the UK, refillable tanks are capped at 2 ml, and nicotine e-liquid is limited to 20 mg/ml in refill bottles of no more than 10 ml. The 2 ml version is therefore the one sold legally in British shops. For the Cthulhu, no capacity is published consistently across the listings consulted, so check the version on sale before buying.

G80 or G80S, the variant that changes what the boro AIO does

The letter S barely stands out in a product list. Yet it separates a pod device open only to the brand’s own boro tank from a boro AIO open to every boro tank.

For the single-pin version, Lost Vape highlights three adjustable airflow pins and compatibility with all boro tanks, including other tank shells once the chimney is swapped. For the two-pin G80, the listing highlights the UB AIO pod and its calibrated coils, with the Centaurus Boro as the alternative. Ordering the G80 to run another brand’s boro tank therefore means buying a device its maker does not list as compatible.

Verdict by vaper profile

Neither device covers every need. Three profiles cover most buyers of this format.

• For a first step into the format, the Centaurus G80 with its UB AIO pod, to try the object without building coils, knowing its listing pairs it on the boro side with the brand’s Centaurus Boro only.
• A vaper who wants to switch between several boro tanks without giving up power can look at the Centaurus G80S, the more open of the pair, with 80 W and a published TPD version.
• The builder who tunes the draw to the tenth will prefer the Cthulhu RBA AIO 2, for its seven pins and dedicated deck, as long as 60 W covers their builds.

The two sets of listings are not equally precise. The G80 range listing says plainly what the box accepts and what the tank holds, while the Cthulhu listings leave capacity, resistance range and screen type without a consistent answer, which means one more check before buying.

FAQ

Five questions the listings for these two devices leave open, and which come up in every comparison of the format.

Does a boro AIO take a 21700 cell?

Not the two models compared here, which are built around an 18650. A 21700 cell is 21 mm across and 70 mm long, so it does not fit a cavity sized for an 18650 of 18 mm by 65 mm. Boro AIO devices for 21700 cells exist, but they are different products.

What does DNA mean on a boro AIO?

DNA refers to the chipsets made by the American firm Evolv, fitted to some high-end boxes. The listings for the Centaurus G80S and the Cthulhu RBA AIO 2 consulted here do not mention a DNA chip.

Does a boro AIO suit a tight mouth-to-lung draw?

Yes, provided you close down the airflow and pick a higher resistance. The Centaurus accepts up to 2 ohms, and the smallest pin on both devices has an inner diameter of 1 mm.

Which coils fit the UB AIO pod?

Lost Vape lists UB Ultra coils of 0.15, 0.2 and 0.3 ohm. The brand’s other UB coils are not on that list, so their compatibility is still to be checked.

Will a boro AIO fit in a pocket?

The Centaurus measures 82.5 mm tall, 47.3 mm wide and 31.2 mm deep, with a listed net weight of about 131 grams. That is the size of a small wallet, thicker than a pod but with no atomiser sticking out.

Boro AIO, the G80S and the Cthulhu AIO 2 by profile

The duel fits in one sentence. The Centaurus G80S has the clearest listing, the higher power and a published 2 ml version, while the Cthulhu RBA AIO 2 serves the builder who puts airflow tuning first.

Before ordering a boro AIO, two checks avoid an easy mistake, the S in the Lost Vape model name and the capacity of the version on sale. The rest comes down to a taste for building, a subject we cover in our look at what the word coil really means.
