GeekVape Aegis Solo 5 Vape Kit

The GeekVape Aegis Solo 5 Vape Kit is a rugged 100W sub-ohm kit that runs on one removable 21700 or 18650 battery, with an IP68 build, AS Chip 4.0 and the Z Subohm Tank 5. A 1.08-inch colour screen and Smart and Power modes make it easy to set up, and because the battery is swappable you can carry a charged spare and never wait on a charger. If you want a tough direct-to-lung kit for daily carry, it is worth a close look.

This page covers what you need to buy with confidence: the IP68 rating explained properly, battery safety, the coils and wattages, and what is in the box. You can also browse the wider GeekVape range to compare.

What Is the GeekVape Aegis Solo 5?

The Aegis name is GeekVape's rugged range, built around one idea: a vape that survives real life. The Solo 5 follows the Aegis Solo 3 with a larger screen, support for 21700 batteries as well as 18650s and a new A-Lock function. Out of the box it is a direct-to-lung (DTL) kit, with 0.2ohm and 0.4ohm Z XM mesh coils made for big, warm vapour.

Unlike the Aegis Mini 5, which has a built-in battery, the Solo 5 takes a single external cell. That is good long-term value, because when a battery ages you replace the cell, not the whole device. Still choosing between kits? Browse our vape kits to compare.

Key Features

• IP68 build. Dust-tight and rated for water immersion, so it is designed to cope with rain, spills and accidental drops.
• Swappable 21700 or 18650 battery. One external cell, with an 18650 adapter in the box. Carry a charged spare. The battery is not included.
• AS Chip 4.0. 5W to 100W output, with Smart and Power modes.
• Z Subohm Tank 5. 2ml (UK TPD), top push-fill and adjustable top airflow.
• Z XM mesh coils. 0.2ohm and 0.4ohm in the box, for warm, cloudy DTL vaping.
• 1.08-inch colour TFT screen. Wattage, battery level, coil resistance and mode at a glance, with an A-Lock function.

Built Tough: IP68 Explained

IP68 is a two-part rating. The first number covers dust and the second covers water, and together they describe what the Solo 5 is built to handle. GeekVape also describes the build as shock resistant, but that is its own claim rather than part of the IP rating.

To be clear, the Solo 5 is water-resistant (IP68), not waterproof. The rating applies to the mod only, so do not submerge it deliberately, and dry the mod and the USB-C port before charging. Seals can wear over time, so treat the rating as protection against accidents rather than a feature to test.

Battery and Safety

The Solo 5 takes one external battery, and one is not included. It runs on a 21700 cell, or on an 18650 using the adapter in the box. A 21700 is physically larger and generally offers more capacity, so it tends to run longer between charges, while an 18650 works well if it is what you already own.

At up to 100W the battery is doing real work, so choose and look after it carefully:

• Buy a genuine, high-drain cell from a reputable brand, with a continuous discharge rating suited to 100W use.
• Check the wrap is intact. Never use a damaged or re-wrapped battery.
• Do not carry loose batteries with keys, coins or other metal. Use a case.
• Charge on a safe, flat surface and do not leave a battery charging unattended or overnight.
• Use a dedicated external charger where you can, which suits battery health, especially if you rotate spares.
• Keep batteries out of reach of children and pets.

Rotating two cells means one is always charged and ready, which is the real advantage of a removable battery.

Smart Mode vs Power Mode

Smart Mode reads the coil you have fitted and sets a sensible wattage for it automatically. If you would rather not think about settings, it is the simple choice.

Power Mode is variable wattage. You choose the output yourself, from 5W up to 100W, to fine-tune flavour and vapour. Most people start in Smart Mode and move to Power Mode once they know the wattage they prefer on a given coil.

Tank, Coils and Wattage

The Solo 5 takes GeekVape Z XM mesh coils. Two are in the box: a 0.2ohm coil, pre-installed, and a 0.4ohm coil as a spare. A 0.15ohm Z XM coil is also compatible but is not included. Match the wattage to the coil, and always check the pack for each coil's recommended range.

The Z Subohm Tank 5 holds 2ml as standard in the UK, in line with TPD, and the kit is supplied with the 2ml glass. The tank's bubble glass is listed at 5.5ml, but the 2ml glass is the one supplied. It is a top push-fill design with adjustable airflow on top, so you can refill without taking the tank off the mod, and close the airflow down if you want a more restricted draw.

1. Close the airflow. Turn the top airflow closed before you fill.
2. Fill. Open the push-to-refill port on top of the tank and add your e-liquid. Do not overfill.
3. Close and prime. Close the port, then let a new coil sit filled for a few minutes before the first draw, and take gentle first puffs to avoid a dry hit.

Which E-Liquid to Use

With sub-ohm coils, use a high-VG e-liquid of 70% VG or more. Shortfills at a lower nicotine strength are the usual choice, and you can browse our shortfill e-liquids to find a flavour. Sub-ohm coils produce a lot of vapour, so higher strengths would be far too harsh.

Nicotine salts and higher-strength 50/50 e-liquids are not suited to these coils, so keep them for pod kits and higher-resistance coils.

Charging

The Solo 5 charges the battery in the mod over on-board USB-C, rated 5V/2A. A USB-C cable is not included, so you will need your own. Charging time depends on the battery and the charger, and many people prefer an external charger, particularly when rotating spare cells. Always charge on a safe surface and do not leave it unattended.

The 1.08-inch colour TFT shows wattage, battery level, coil resistance and the current mode. The A-Lock function, with a status light, locks the fire button and settings so nothing changes by accident in a pocket. The kit is fired by button.

Aegis Solo 5 vs Aegis Solo 3 vs Aegis Mini 5

The Solo 5 sits alongside two other Aegis kits, so here is how they compare. The Solo 3 and Mini 5 figures are as listed by GeekVape and UK retailers.

In short, the Solo 5 adds 21700 support, a larger screen and the A-Lock over the Solo 3, while keeping the same chip, power range and IP68 rating. Against the Mini 5, the choice is about the battery: choose the Solo 5 for swappable power and the higher IP rating, or the Mini 5 for a built-in battery with nothing to buy.

Colours

The Aegis Solo 5 comes in six colours: Black, Blue, Grey, Purple, Red and Silver. Every colour has the same specification, so only the finish changes.

Specifications and What's in the Box

You will need your own battery, USB-C cable and e-liquid to get started.

Frequently Asked Questions

Does the GeekVape Aegis Solo 5 come with a battery?

No. The Solo 5 takes one external battery, and it is not included, so you need to buy one separately. It runs on a 21700 cell, or on an 18650 using the adapter that comes in the box. Because the battery is removable, you can carry a charged spare and swap it in, rather than waiting for the mod to recharge.

What battery should I use in the Aegis Solo 5, and is it safe?

Use a genuine, high-drain 21700, or an 18650 with the adapter, from a reputable brand, with an intact wrap and a discharge rating suited to 100W use. Never use a damaged or re-wrapped cell, do not carry batteries loose with keys or coins, and charge on a safe surface. A dedicated external charger is recommended for battery health.

Is the Aegis Solo 5 waterproof?

No. It is water-resistant to IP68, not waterproof. That means it is dust-tight and, as listed by UK retailers, withstands immersion to 1.5 metres for 30 minutes on the mod, so rain, spills and an accidental drop in a puddle should not be a problem. It is not made for deliberate underwater use, and you should dry the USB-C port before charging.

How much e-liquid does the Aegis Solo 5 tank hold?

The Z Subohm Tank 5 holds 2ml as standard in the UK, in line with TPD, and the kit is supplied with the 2ml glass. The tank's bubble glass is listed at 5.5ml, but the 2ml glass is the one supplied. It is a top push-fill tank, so you refill from the top without removing the tank from the mod.

What coils does the Aegis Solo 5 use, and which are included?

It uses GeekVape Z XM mesh coils. The kit includes a 0.2ohm coil (70 to 80W), already installed, and a 0.4ohm coil (50 to 60W) as a spare. A 0.15ohm coil (70 to 85W) is also compatible but is not included. These are sub-ohm, direct-to-lung coils, so swap the coil when flavour fades or you notice a burnt taste.

What wattage should I run the Aegis Solo 5 coils at?

Match the wattage to the coil: the 0.2ohm runs at 70 to 80W, the 0.4ohm at 50 to 60W and the optional 0.15ohm at 70 to 85W. In Smart Mode the kit sets a sensible wattage for the coil. In Power Mode, start at the lower end of the range and work up to taste. The maximum output is 100W.

Is the Aegis Solo 5 MTL or DTL?

It is a sub-ohm, direct-to-lung (DTL) kit. The included Z XM coils and the adjustable top airflow are made for warm, cloudy DTL draws, and you can close the airflow down for a more restricted draw. It is not a mouth-to-lung (MTL) kit, so if you want a tight, cigarette-style MTL pull, a pod kit will suit you better than the Solo 5.

What is the difference between Smart Mode and Power Mode?

Smart Mode reads the coil you have fitted and sets a sensible wattage for it, which is ideal if you would rather not think about settings. Power Mode is variable wattage, so you set the output yourself and fine-tune flavour and vapour. Most people start in Smart Mode and switch to Power Mode once they know the wattage they prefer on each coil.

What e-liquid should I use in the Aegis Solo 5?

Use a high-VG e-liquid, ideally 70% VG or more, such as a shortfill at a lower nicotine strength. These sub-ohm coils make a lot of warm vapour, so nicotine salts or high-strength 50/50 liquids would be far too harsh. If you want nicotine in a shortfill, add a nic shot and keep the final strength low for comfortable DTL vaping.

How do I charge the Aegis Solo 5, and is a cable included?

The Solo 5 charges the battery in the mod over on-board USB-C, rated 5V/2A. A charging cable is not included, so you will need your own. Charging time depends on the battery and charger, and many people prefer an external charger when rotating spare cells. Charge on a safe surface and do not leave it charging unattended.

How is the Aegis Solo 5 different from the Solo 3 and the Mini 5?

Compared with the Solo 3, the Solo 5 adds support for 21700 batteries (the Solo 3 takes an 18650), a larger 1.08-inch screen and the A-Lock function, while sharing the AS Chip 4.0, 100W output and IP68 rating. Compared with the Mini 5, the big difference is the battery: the Solo 5 is removable, while the Mini 5 has a 3200mAh built-in battery.

What does the Aegis Solo 5 screen show, and what is in the box?

The 1.08-inch colour TFT shows wattage, battery level, coil resistance and the current mode, and the A-Lock function, with a status light, locks the fire button and settings. The box contains the mod, the Z Subohm Tank 5, 0.2ohm and 0.4ohm Z XM coils, the 18650 adapter, a coil tool and the manual. Supply your own battery, cable and e-liquid.
