Geekvape Aegis, choosing a model by your draw

Tough, sealed, built for the outdoors. The Geekvape Aegis line is always sold on its shell, hardly ever on the puff it delivers. Yet between a dual-battery 200W box and a pocket pod that claims a tight draw, the gap in feel is total. This comparison sorts six models by four criteria, the format, the power source, the coil family and the inhaling style each one targets, so the choice starts from how you draw rather than from the spec sheet.

Geekvape Aegis, the short answer by draw

Three families make up the range. Legend 5, Solo 5 and Solo 3 are boxes aimed at direct-to-lung vaping, with tanks and Z coils from 0.15 to 0.4 ohm. In the middle sits the Mini 5, because it takes the B series, which reaches all the way down to MTL. As for the Hero 5 and Nano 3 pods, they cover RDL and, in the second case, the tight draw too.

Put simply, a Geekvape Aegis does not set the draw on its own. Whatever coil you fit decides, and the box only supplies the power that coil asks for.

Toughness is the design brief for the whole range. Spec sheets published by Geekvape describe a “tri-proof” build, water, shock and dust resistant, tied to the IP68 standard. For the Legend 5, the maker puts a number on it, immersion down to 1.5 metres for 30 minutes.

One exception is worth flagging. The Mini 5 is rated IP67 on its own sheet, one step below the IP68 models. If you vape near water, that detail matters more than the wattage.

This shared base says nothing about the draw, and that is where the six models part ways.

The six Geekvape Aegis models side by side

This table brings together six Geekvape Aegis models listed in the maker’s catalogue at the end of September 2026. Its last column shows the inhaling style each one suits best with the coils designed for it.

Aegis Solo 5	Box	One 21700 or 18650 battery	Z Subohm Tank 5 recommended	DTL
Aegis Solo 3	Box	Built-in 3000mAh battery or 18650, depending on version	Z Subohm 2021, Z coils	DTL
Aegis Mini 5	Compact box, up to 100W on the maker’s sheet	Built-in battery	510 connection, B series	DTL, RDL or MTL depending on the coil
Aegis Hero 5	Pod, 50W	Built-in 2000mAh battery	Hero cartridge, B coils	RDL
Aegis Nano 3	Pod	Built-in 1600mAh battery	N cartridge	RDL and MTL

The direct-lung Aegis boxes, Legend 5, Solo 5 and Solo 3

Three boxes follow the same logic, plenty of power and Z coils designed for direct-to-lung vaping. What separates them is the power source and the size more than the puff they produce.

Legend 5, the dual 18650

The Legend 5 reaches 200W on two 18650 batteries. Sold as a kit with the Z Subohm Tank 5, it takes Z XM coils rated at 70 to 85W for the 0.15 ohm, 70 to 80W for the 0.2 ohm and 50 to 60W for the 0.4 ohm. None of those ranges comes close to the box’s ceiling, so it keeps plenty in reserve.

Those coils are made for DTL. The maker advises against nicotine salts in them and pairs them with freebase e-liquids at 3mg or less.

Solo 5, a single 21700

The Solo 5 takes one 21700 or 18650 battery. It is recommended with the same Z Subohm Tank 5 and presented as a box built for big clouds, which places it firmly in direct-lung territory.

Solo 3, built-in battery or external cell

The Solo 3 comes in two versions, one with a built-in 3000mAh battery, the other with an external 18650. Its tank, the Z Subohm 2021, fills and draws air from the top. It ships with 0.2 ohm (70 to 80W) and 0.4 ohm (50 to 60W) Z coils, two values that keep it on the direct-lung side.

The Mini 5 and the B series, from DTL down to MTL

The Mini 5 is the only box in the range whose sheet lists the B series, a coil family that covers almost every draw. It goes up to 100W on Geekvape’s sheet, charges to 80% in 40 minutes at 5V and 3A, and keeps a 510 connection that takes a B-compatible tank such as the Z Nano 3. Some UK listings show it as a 75W device, so check the wattage on the product page.

The B series comes in eight versions, three of them MTL.

B coil	Wattage range	Intended use
0.15 ohm	60 to 75W	DTL
0.2 ohm	50 to 58W	DTL
0.3 ohm	30 to 38W	DTL
0.4 ohm	25 to 35W	In between, often RDL
0.6 ohm	15 to 25W	In between, often RDL
0.6 ohm MTL	15 to 25W	MTL
0.8 ohm MTL	12 to 16W	MTL
1.2 ohm MTL	8 to 12W	MTL

E-liquid guidance comes with that table. The 0.2 and 0.3 ohm are paired with freebase at 3mg or less, the 0.8 and 1.2 ohm with nicotine salts or freebase up to 9mg. In the UK, nicotine e-liquid is capped at 20 mg/ml and sold in bottles of no more than 10 ml.

For choosing a box, the upshot is clear. The Mini 5 can follow a vaper from a tight draw to direct-lung without a new device, only a new coil. Our method for switching from MTL to DTL walks through that progression step by step.

The Aegis pods, Hero 5 and Nano 3

The two pods in the range drop the 510 connection for a dedicated cartridge. They gain in size what they lose in tank choice, and each targets a different draw.

Hero 5, a 50W pod for RDL

The Hero 5 delivers up to 50W from a built-in 2000mAh battery and uses the Boost version of the B coil. That ceiling sorts the series. The 0.15 ohm, which needs 60 to 75W, falls outside its range, and the 0.2 ohm only fits at the bottom of its own.

The 0.3 to 0.6 ohm values sit entirely within it. They steer the Hero 5 towards a moderate or restricted direct draw, the RDL style covered in our guide to restricted direct to lung vaping.

Its cartridge is listed at 6.5ml on the international sheet. UK rules cap refillable tanks and pods at 2ml, so any version sold in the UK must hold no more than that.

Nano 3, the pod that moves from RDL to MTL

The Nano 3 is the only model in the range explicitly presented for two styles, RDL and MTL. Its built-in 1600mAh battery powers an N cartridge, and it fires either from a button or on the draw.

For a tighter draw, you usually close the airflow down along with the wattage. Our guide to vape airflow settings explains how to do it one notch at a time.

Which Geekvape Aegis suits your vaping style

The verdict depends on your draw before the wattage, and one model stands out for its versatility.

For a tight draw, the Nano 3 is the most direct choice, since it is the only pod in the range designed for MTL. Fitted with a 0.8 or 1.2 ohm B MTL coil, the Mini 5 targets the same action in a box format.

For RDL, the Hero 5 makes the most sense. Its wattage and the 0.3 to 0.6 ohm coils meet exactly in that zone, with a bigger battery than the Nano 3.

On the direct-lung side, the Legend 5 wins as soon as you want headroom, with its 200W and two batteries. The Solo 5 and Solo 3 suit anyone who prefers a more compact single-battery box, and the Solo 3 adds the option of a built-in battery.

That leaves the vaper who is still undecided. For them, the Mini 5 is the most versatile of the Geekvape Aegis models, and our comparison of MTL vs DTL vaping helps settle the question before buying.

FAQ

Five questions that come up about the range, from its name to looking after the coils.

What does the name Aegis mean?

Aegis is the Latin form, used in English, of the Greek word for the shield that mythology gives to Zeus and Athena. It gave the phrase “under the aegis of”, meaning under the protection of. The name suits a range sold first on how well it stands up to knocks and water.

Which battery should you use in an Aegis with an external cell?

The format is set by the box, 18650 for the Legend 5 and the external-battery Solo 3, 21700 or 18650 for the Solo 5. Pick a battery from a recognised brand rated for high drain, and set aside any cell with a damaged wrap.

Can you fit an MTL tank to an Aegis box?

Yes, every box in the range keeps a 510 connection. Stay within the wattage range printed on the tank’s coil, which is usually low for MTL, then adjust the airflow to the draw you want.

How should you set up an Aegis the first time?

On the Solo 3, a Smart mode picks a suitable wattage range for the Z coil fitted. On the other models, start at the bottom of the range printed on the coil and step up in small increments until the feel is right.

When should you change the coil in an Aegis?

As soon as a burnt taste appears or the flavour fades, and also when you switch e-liquid flavour. The maker puts the life of a Z XM coil at around 50 to 60 ml of e-liquid, and a B MTL coil at around 20 to 30 ml, depending on use.

Geekvape Aegis, the coil decides before the box

Behind a shared shell, the Geekvape Aegis range covers the three main inhaling styles. The Legend 5, Solo 5 and Solo 3 boxes serve direct-lung vaping, the Hero 5 serves RDL, the Nano 3 serves MTL, and the Mini 5 moves between them thanks to the B series.

Choosing an Aegis therefore means choosing a coil and a way of drawing first. Reading kit by the draw rather than by the wattage on the box is the approach we apply to every device we look at on this site.
