Geekvape Legend 5 tops our box mod ranking

Three box mods running on external batteries compete for the same toughened mod buyer, and the Geekvape Legend 5 turns up with the loudest pitch of the three, 200 watts, twin 18650 cells and an IP68 rating. Against it, Vaporesso’s Armour Max pushes to 220 watts and Voopoo’s Drag X3 plays the single cell card. We ranked them on verifiable criteria only, namely power, batteries, tank capacity, weight, coils and stated protection.

The ranking in brief, with the Geekvape Legend 5 on top

The Geekvape Legend 5 takes first place. It is the only one of the three to claim an IP68 rating on its official page, and its 1.08 inch colour screen remains the most complete of the trio.

Vaporesso’s Armour Max follows closely, more powerful on paper and more generous on capacity, but with no stated protection. The Drag X3 closes the ranking, not through any weakness, but because a single cell places it in a lower battery life category.

Three mods in one table

Every row below comes from the official Geekvape, Vaporesso and Voopoo pages, with one exception, the Legend 5 weight, taken from a retailer’s listing. An empty cell means the brand does not publish the figure.

Criterion	Aegis Legend 5	Armour Max	Drag X3
Batteries	2 x 18650, external	2 x 21700 or 18650, external	1 x 18650 or 21700
Power	5 to 200 W	5 to 220 W	5 to 80 W
Tank capacity supplied	5.5 ml (TRPR cap 2 ml)	8 ml (TRPR cap 2 ml)	5 ml (TRPR cap 2 ml)
Weight	171 g	186 g without batteries
Dimensions	146 x 56 mm	157 x 56.5 x 34 mm
Coils	Z Series, 0.1 to 3.0 ohms	GTi 0.2 and 0.4 ohm	PnP X 0.15 and 0.3 ohm
Screen	1.08 inch colour TFT	0.96 inch TFT	1.66 inch touchscreen
Stated protection	IP68

Two figures deserve a careful read. The Armour Max weight is given without batteries and the Legend 5 figure comes from a retailer, so the two values cannot be compared to the gram.

In first place, the Geekvape Legend 5

Geekvape carries over to this fifth generation the recipe that made the Aegis series, with a reinforced chassis and a revised chipset.

What IP68 actually covers

The IP68 rating covers immersion and dust, not impacts. Geekvape adds a shock resistance claim on its product page, but that claim is not tied to any named standard.

In practice, a Geekvape Legend 5 that falls into a puddle can be rinsed off. The same fall onto a tiled floor remains a gamble, exactly as with any metal mod.

The AS 4.0 chipset and its five modes

The mod lists five operating modes, including an ECO mode and a temperature control mode, with a firing time given as 0.01 seconds. Its accepted resistance range runs from 0.1 to 2 ohms on the mod side.

The Z Sub-Ohm tank supplied with the kit takes the Z series, from 0.1 to 3.0 ohms. That mismatch between the two ranges explains why a 3 ohm coil fitted to the tank is not recognised by the mod.

Second place, the Vaporesso Armour Max

On paper, the Armour Max beats the Legend 5 wherever the numbers are big. It loses on what the numbers leave out.

Its 220 watts and an iTank T quoted at 8 ml on international spec sheets make it the most generous of the trio, with room for two 21700 cells instead of two 18650s. It is the only model in the ranking to leave that choice of format open.

On the other hand, no water resistance rating is claimed on its product page, and the 186 grams quoted exclude the batteries. Loaded with two 21700s, it becomes noticeably heavier than the Legend 5 weighed complete.

Third place, the Voopoo Drag X3

The Drag X3 does not play in the same battery life category, and that is a deliberate choice by Voopoo rather than a flaw.

One cell, two formats accepted

The mod takes either an 18650 or a 21700, which lets you match its size to the day ahead. Its power tops out at 80 watts, plenty for the 0.15 and 0.3 ohm PnP X coils supplied with it.

The only touchscreen in the ranking

With its 1.66 inch touch panel, the Drag X3 has the most modern interface of the three. It is also the only one without a conventional mechanical fire button, since activation works through a capacitive sensor.

That choice divides opinion. It makes adjustment quick and reading pleasant, but it adds a sensitive surface to a device that spends its life in a pocket.

What each mod needs before its first puff

The shelf listing says little in this segment, since none of the three mods is sold ready to use. A battery is always missing from the box.

The Geekvape Legend 5 kit needs two flat top 18650 cells. So does the Armour Max, which the retailer we checked listed as a mod only, plus a tank if you do not already own one. The Drag X3 needs just one cell.

Counted this way, the Legend 5 kit turns out to be the most complete package of the three, since it already includes the tank and two coils.

Flat tops, a detail rarely mentioned

Geekvape states on its page that the 18650 cells used must have flat terminals at both ends for the battery door to close. A button top cell, common among cells made for other uses, simply stops the door from shutting.

That mechanical constraint appears on almost no retailer listing, and it accounts for some of the product returns on this model.

Which mod for which use

An overall ranking only makes sense against a specific use. Here is where we would point each of the three models.

Demanding outdoor use

The Geekvape Legend 5 without hesitation, for its IP68 rating and its dual cell format. It is the only one of the three to show a rated protection on its manufacturer page.

High power vaping at home

The Armour Max, for its 220 watts and the freedom to pair it with the atomiser of your choice. Its 8 ml tank figure, however, would shrink to 2 ml under British rules.

Discretion and a smaller footprint

The Drag X3, still the only one to run on a single cell. Anyone who would rather have a built-in battery than cells to charge will find a dedicated comparison in our Vaporesso Armour Ultra vs Armour Max duel.

Frequently asked questions

These five questions come up regularly around box mods with external batteries and are not covered above.

What current can these mods deliver?

Geekvape quotes a maximum output current of 45 amps and a maximum voltage of 12 volts for the Legend 5. Those values, rather than the displayed wattage, determine the lowest rebuildable build a mod will accept.

Will a 21700 cell fit the Legend 5?

No. The official page only mentions twin 18650s. In this ranking, only the Armour Max and the Drag X3 take the longer and wider 21700.

Does the 8 ml capacity apply in the UK?

No. The Tobacco and Related Products Regulations 2016 limit tanks to 2 ml, so the 5.5 ml and 8 ml figures belong to markets outside that rule.

Can the batteries be charged inside the mod?

All three models have a Type-C port for internal charging. An external charger is still better for battery longevity and lets you monitor each cell individually.

What does the ECO mode on the Geekvape Legend 5 do?

It is an output profile that limits power to stretch the time between two charges. It sits among the five modes of the AS 4.0 chipset, alongside normal, custom, smart and temperature control.

What the Geekvape Legend 5 ranking means for your purchase

The Geekvape Legend 5 earns its first place because it is the only one to back its toughness with a named rating, not because it shows the biggest number. In this segment maximum power almost never translates into real use, since nobody vapes at 200 watts day to day.

What does translate into real use is battery availability, screen readability and a device’s ability to survive a fall. On those three counts, the Geekvape Legend 5 remains the mod we would put first.
