The Aegis Line in 2026: More Models, Same Core Promise
Geekvape Vapes has been building the Aegis series long enough that it has a genuine track record — not just marketing claims. The original Aegis was a single-26650 battery mod, and the dual-18650 Aegis Legend followed. Since then, the line has branched into multiple form factors: the box-mod Legend series for sub-ohm DTL vapers, the compact Aegis Force pod-mod, and smaller options like the Aegis Hero and Aegis Nano. Each device carries the same Tri-Proof DNA — waterproof, dustproof, and shockproof — but the specs, coil families, and intended use cases differ enough that picking the wrong one is a real possibility if you buy without reading first.
This guide focuses on the three models UK buyers ask about most in 2026: the Aegis Legend 3, the Aegis Legend 5, and the Aegis Force. It covers verified specs, which coils actually fit, what the vaping modes mean in practice, and a few setup habits that keep coils alive longer.
Aegis Legend 3 and Legend 5: Specs Side by Side
Both the Legend 3 and Legend 5 are dual external 18650 box mods — batteries are sold separately, which catches some UK buyers off guard at checkout. Neither includes cells in the box.
Aegis Legend 3 runs on the AS Chip 4.0 and outputs 5–200W (the Carrera Edition goes to 230W, but standard units cap at 200W). The resistance range is 0.1–3.0Ω, the maximum output current is 45A, and it charges via USB-C at up to 5V/3A. The display is a 0.96-inch TFT colour screen. Dimensions sit at roughly 55.4 mm × 140.5 mm. The Legend 3 introduced Smart Lock — a palm-recognition sensor under the leather back panel that automatically unlocks the device when you pick it up and locks when you set it down. It works well in most conditions, though it won’t respond through thick gloves.
Aegis Legend 5 shares the same AS Chip 4.0 platform and the same 5–200W output range, but moves to a larger 1.08-inch TFT colour screen with customisable dynamic light strips. The firing speed is quoted at 0.01 seconds. The Legend 5 adds a vibration alert when the battery drops to around 25% — a small change that turns out to be genuinely useful if you vape on the move. Both mods carry an IP68 Tri-Proof rating, meaning they’re tested to withstand submersion to 1.5 metres for 30 minutes, full dust exposure, and drops from up to 1.4 metres.
For most UK buyers the practical difference between the two comes down to screen size and that battery alert. The Legend 5’s larger display is noticeably easier to read in daylight. If you’re upgrading from a Legend 3 purely for performance, you probably won’t notice a difference in vapour quality — the chipset is the same. If you want the bigger screen and the vibration notification, the Legend 5 is the better buy.
Aegis Force: The Pod-Mod Option
The Aegis Force sits in a different category entirely. It’s a pod-mod with a built-in 3200mAh battery — no external cells required — and an 80W maximum output. The tank uses top airflow and bottom-fill via a silicone plug, and the pod attaches magnetically. The display is a 0.96-inch TFT screen with a single fire button for navigation.
The Force uses B Series coils rather than Z Series, and the supported resistance range covers both DTL and MTL styles: 0.15Ω, 0.2Ω, 0.3Ω, 0.4Ω, and 0.6Ω for direct-lung vaping, and 0.8Ω and 1.2Ω for mouth-to-lung. The kit ships with a 0.4Ω B Boost coil (25–35W, restricted direct draw) and a 0.2Ω coil (50–58W, open DTL). Smart Mode is available on the Force and automatically selects the best wattage for the fitted coil — a practical feature for anyone who doesn’t want to manage settings manually.
The Force weighs around 183g with the pod installed, which puts it somewhere between a compact kit and a full box mod. If you want Aegis-level build quality without the hassle of sourcing external 18650s, it’s probably the most approachable entry point in the current range.
Coil Compatibility: What Fits What (and Why It Matters)
Getting coil compatibility wrong is the most common mistake with Aegis devices, because Geekvape runs three distinct coil families across the range and they are not interchangeable.
Z Series coils are the correct choice for the Aegis Legend 3 and Legend 5. These are push-fit coils compatible with the Z Fli Tank (Legend 3), the Z Sub-Ohm Tank 2021 (Legend 5 kit version), and several other Z-designated tanks. The resistance options relevant to UK sub-ohm vapers are the 0.15Ω XM coil (70–85W), the 0.4Ω XM coil (50–60W), the 0.25Ω Dual (45–57W), and the 0.2Ω (70–80W). Z Series coils are designed for high-VG e-liquids — a 70VG/30PG ratio or higher is the standard recommendation for DTL use.
B Series coils cover the Aegis Force, Aegis Boost, Aegis Boost Plus, Aegis Hero, and Zeus Nano Tank. They’re constructed from KA1 Kanthal mesh and come in both a Classic version (MTL/RDTL, 0.6Ω and above) and a Boost version (DTL, 0.2Ω–0.4Ω). The 0.6Ω pairs well with 50/50 freebase or nic salt e-liquids; the 0.2Ω and 0.4Ω options work best with high-VG shortfills. B Series coils are sold in packs of five and are widely available from UK retailers.
P Series coils apply to the Aegis Boost Pro 2 (B100) and a handful of other Boost-family devices. They’re not relevant to the Legend or Force lines.
One naming note worth flagging: Geekvape rebranded the original Aegis Boost coils as B Series coils. The product is identical — only the packaging changed. If you’re searching for replacements and see both names, they’re the same coil.
Vaping Modes Explained, and How to Set Up Your Aegis Mod
Both Legend models share the same mode set via the AS Chip 4.0: POWER (manual wattage control in full-watt increments), SMART (auto-detects coil resistance and sets wattage), ECO (caps power to extend battery life), BOOSTING (increases initial power for a stronger first puff), TCR (temperature control with custom resistance coefficients for Ni, SS, or Ti wire builds), and MEMORY (saves up to five wattage presets for quick recall). For most UK vapers running stock Z Series coils, SMART or POWER mode is all you’ll ever need. TCR is relevant if you build your own coils, which is a small subset of users.
For first-time setup, a few habits make a real difference. Prime new coils before use — drop e-liquid directly onto the exposed cotton ports and let the coil sit in the filled tank for at least five to ten minutes before firing. This prevents the dry, acrid hit that comes from a coil that hasn’t fully saturated. Keep e-liquid above the coil’s wicking ports at all times; running the tank low is the fastest way to burn a coil prematurely. Stay within the wattage range printed on the coil itself — the 0.15Ω Z coil is rated 70–85W, and pushing it to 100W will shorten its life noticeably. Low-resistance coils used at higher wattages tend to need more frequent replacement than higher-resistance coils run at moderate power.
For the Legend 3 specifically, the Smart Lock sensor sits under the leather back panel. It won’t activate with gloves on, and it can be switched to Button Lock mode or disabled entirely through the settings menu if the auto-lock behaviour doesn’t suit you.
UK buyers should also be aware that TPD-compliant versions of these kits ship with 2ml tank capacity rather than the 5.5ml global version. The tank hardware is identical — only the glass tube differs. Spare 5.5ml glass tubes are available separately if you want the larger capacity, though the 2ml restriction applies to any e-liquid sold in the UK.
What to Look For When Buying in the UK
A few practical considerations before purchasing. First, 18650 batteries are not included with the Legend 3 or Legend 5 — budget for two high-drain cells (Samsung 25R, Sony VTC5A, or equivalent) alongside the mod. An external charger is worth having too, as swapping cells is faster than waiting for USB-C to top up. Second, check that the seller is stocking genuine Geekvape hardware rather than grey-market units without UK warranty support. Third, confirm the tank version: UK-legal kits include the 2ml TPD-compliant glass, which is standard from any reputable UK retailer.
Vape Online Store stocks Geekvape kits and accessories including coil replacements, with fast UK delivery and genuine products sourced directly from brand distributors. Their Geekvape kits are a useful starting point if you want to browse current stock alongside compatible pods and coils. Replacement Geekvape pods and coils are listed separately, making it straightforward to stock up on Z Series or B Series consumables at the same time as the mod.
For the Aegis Force specifically, the built-in battery removes the external cell question entirely — but it does mean the device is eventually non-serviceable once the battery degrades. Most users find the 3200mAh capacity sufficient for a full day of moderate vaping before needing to charge. For heavy users or long days away from a socket, the dual-18650 Legend models offer more flexibility since you can carry a spare set of charged cells.
The Aegis line’s longevity in the market is partly down to build quality and partly due to consistent coil availability. Z Series and B Series coils are stocked by most UK vape retailers, which means you’re unlikely to be left searching for consumables six months after purchase — a practical consideration that’s easy to overlook when choosing a mod.
