Geekvape Aegis Legend vs Aegis Solo: Which Mod Should You Buy in the UK?

Two Mods, One DNA

Geekvape built the Aegis range on a single promise: a vape mod that survives the kind of daily abuse most hardware quietly fails. Drop it on concrete. Leave it in the rain. Forget it in a jacket pocket through a wash cycle. The Aegis series has absorbed all of that and kept firing.

But within that range, the Aegis Legend and the Aegis Solo target different vapers — and confusing the two is an easy mistake to make, especially when they share the same rugged aesthetic, the same IP67/IP68 tri-proof protection, and the same general design language of rubberised sides, leather inlay, and zinc-alloy frame.

The real differences come down to power ceiling, battery configuration, physical size, and who the device is actually built for. This comparison cuts through the overlap and tells you which one to buy based on how you actually vape.

Specs at a Glance

Both mods are TPD compliant in their UK versions, and both accept standard 510-thread tanks — so your existing tanks will work on either device.

Power and Performance: Where They Actually Differ

The Aegis Legend runs on dual 18650 batteries and tops out at 200 watts. The Aegis Solo runs on a single 18650 and caps at 100 watts. That gap matters more than it sounds.

If you vape sub-ohm coils in the 0.15–0.2Ω range — the kind found in Geekvape’s own Z Series coils, rated for 70–90W — the Solo handles that comfortably. Most vapers running mesh coils at 60–80W will never feel constrained by the Solo’s ceiling. But if you’re pushing low-resistance builds or running coils that want 100W+ to perform properly, the Legend is the only option here.

The Legend’s dual-battery setup also means significantly longer session time. With two 3000mAh 18650 cells loaded, you can realistically vape most of a day at moderate wattage without reaching for a charger. The Solo, with one battery, tends to need a top-up or a battery swap mid-afternoon for heavy users — though carrying a spare 18650 and swapping it in 30 seconds is a genuine advantage over internal-battery devices.

Both mods support the same output modes: variable wattage, bypass, temperature control (Ni200, Ti, SS), TCR, and VPC — Geekvape’s wattage curve mode that lets you set up to five different power levels across a single draw. VPC is particularly useful for DTL vapers who want a ramp-up rather than a flat hit. The AS-100 chipset in the Solo fires at a claimed 0.001-second response time, which in practice feels instant. The Legend’s AS chip performs similarly.

Size, Weight, and Everyday Carry

This is where the Solo earns its following. The Aegis Solo is a noticeably smaller mod — compact enough to feel genuinely pocketable, whereas the Legend is a dual-battery box that will fill a jacket pocket and then some.

The Legend’s larger chassis is a direct consequence of housing two 18650 cells side by side. It’s not enormous by box-mod standards, but if you commute, work with your hands, or just dislike bulk, the size difference is real enough to factor into your decision. The Solo’s single-battery form factor keeps it slim and light without sacrificing the Aegis durability that makes the range worth buying in the first place.

For vapers who’ve previously used pod kits or smaller devices and want to step up to a proper mod setup, the Solo tends to be the less intimidating entry point. The Legend suits vapers who already know they want high wattage and are comfortable carrying a larger device.

Both mods use the same general construction: die-cast zinc-alloy frame, silicone rubber exterior, and a leather-like panel. Both have passed IP-rated durability testing for water and dust ingress, and both are shockproof by design. The Legend carries an IP68 rating (rated for submersion beyond 1 metre), while the original Solo sits at IP67. In practice, neither is going to fail because you got caught in British weather.

Pros and Cons

Aegis Legend — Pros

• 200W ceiling suits high-wattage sub-ohm vaping and demanding coil builds
• Dual 18650 batteries mean longer sessions between charges or swaps
• IP68 rating, slightly higher than the Solo’s IP67
• 1.08" TFT colour screen is larger and easier to read
• A-Lock side switch is a clean, practical way to lock the device

Aegis Legend — Cons

• Larger and heavier — less pocketable than the Solo
• Dual 18650 batteries are sold separately, adding to the upfront cost
• Overkill for vapers who vape below 80W

Aegis Solo — Pros

• Compact and light — far easier to carry all day
• Single 18650 keeps costs lower and the device slimmer
• 100W is sufficient for the vast majority of sub-ohm setups
• Same Aegis tri-proof durability in a smaller package
• Easier starting point for vapers moving up from pod kits

Aegis Solo — Cons

• 100W ceiling rules it out for high-power builds
• Single battery means shorter runtime for heavy users
• Smaller screen than the Legend 2’s TFT display

Which One Should You Buy?

The answer mostly comes down to two questions: how high do you vape, and how much does size matter to you?

If you regularly vape above 80W, run low-resistance coils, or chase serious cloud production, the Aegis Legend is the right call. Its 200W output and dual-battery runtime are designed for that use case, and the larger form factor is a fair trade-off for what you get. The Legend is also the better choice if you want the highest-spec version of Aegis durability — the IP68 rating and the TFT colour screen are genuine upgrades over the Solo.

If you vape at 40–80W, want something you can actually pocket, and don’t want to carry two spare batteries, the Aegis Solo is probably the smarter buy. It delivers the same fundamental Geekvape experience — the rugged build, the AS chipset, the full suite of output modes — in a format that’s easier to live with day-to-day. For vapers moving up from a pod kit or a smaller device, the Solo is the more sensible step up.

And if you’re somewhere in the middle — say, 70–90W on a 0.2Ω mesh coil — the Solo handles that fine. You don’t need 200 watts to get excellent flavour and cloud production from a quality sub-ohm tank.

Both mods are available at Vape Online Store, which stocks a range of authentic Geekvape hardware including kits and standalone mods. If you already own a sub-ohm tank and just need the mod, you can pick up either device on its own — though the kit versions typically offer better overall value, especially if you’re building a new setup from scratch.

For replacement coils compatible with both setups, Geekvape’s Z Series coils are worth keeping stocked — they’re compatible with the Z Sub-Ohm Tank that ships with the Legend kit, and the range of resistance options (0.15Ω through 0.4Ω) gives you flexibility depending on your preferred wattage. You can find Geekvape coils and pods alongside the mods themselves.

One thing that doesn’t change between the two: build quality. Geekvape’s Aegis line has a strong track record for longevity, and both the Legend and the Solo are the kind of hardware that vapers tend to hold onto for years rather than months.
