# Aegis Solo 3: what the spec sheet says > Aegis Solo 3: 100W, one 18650 cell, IP68, touch sensing lock, Z Subohm tank. The documented figures and the gaps the product page leaves open. Within the Aegis family, the Solo line holds the single cell slot: less output, less weight in the hand, one battery to manage instead of two. The **Aegis Solo 3** carries the same chipset as its bigger siblings inside a different shell, with a lock that works nothing like theirs. This sheet sets out what the technical documents establish, and what they leave blank. ## Aegis Solo 3: the exact configuration The kit pairs a mod taking one removable 18650 cell, not supplied, with the Z Subohm tank. The mod delivers 5 to 100 watts and recharges over USB-C through a port set into the top, under a silicone flap that plays a part in the sealing. British listings also carry a variant of the same mod with a built in cell instead of the external one, and the two are easy to mix up when shopping. The version described here is the external battery model, which is the one that raises battery handling questions in the first place. The tank uses an 810 drip tip and steps from 23 mm at the base to 29 mm across the reservoir. The complete kit is quoted at around 198 grams, empty and without a cell. Two Z Series coils accompany the kit, along with a spares kit and a replacement glass. ## A touch sensing lock, not a slider This is the most notable design difference from the rest of the range, and it changes daily handling more than the spec sheet suggests. The mechanism asks for no action at all, it reads the presence of a hand. Sensors set around the grip detect contact and unlock the mod when the vaper picks it up. As soon as it is set down, the lock re-engages, which limits accidental firing in a pocket or a bag without anything to remember. Retailer documentation is specific that these sensors respond to skin contact only. A mod resting against an inert object therefore stays locked, which is the behaviour you want for transport. It is worth testing on the day it arrives, because a lock you have not verified is a lock you are trusting on faith. ## The AS 4.0 modes on the Aegis Solo 3 The mod carries the same AS 4.0 circuit as the higher models, but its 100 watt ceiling changes what each mode does in practice. Here is what the manufacturer sheets describe, mode by mode. Power mode leaves the wattage entirely to the user up to the ceiling. Smart mode reads the fitted coil and proposes a band matched to it, which is the setting most owners leave it on. Boosting mode sets output at the highest value the detected coil accepts, Eco mode at the lowest. TCR mode opens temperature control, and the Memory function keeps the settings of five different atomisers or coils, so swapping between two tanks does not mean redialling anything. ## Coils, airflow and the UK 2 ml cap The single condition for clean operation is staying inside the power band the coil maker prints on the coil itself and on its packaging. The Z Series range is documented value by value, each with a suggested minimum vegetable glycerine content, and reading that printed band is the whole of the method. A liquid too thin for the coil fitted runs through the wick instead of feeding it, which is the most common cause of a kit that leaks from the first tank. The higher the VG figure a coil asks for, the thicker the liquid it expects, and British 10 ml bottles state their VG ratio on the label. Capacity is where the United Kingdom parts company with other markets. Refillable tanks sold here are capped at 2 ml, so the Z Subohm supplied with a UK kit holds 2 ml rather than the larger reservoir quoted on international sheets. Nicotine containing e-liquid is capped at 20 mg/ml and sold in 10 ml bottles, and none of it is for sale to under-18s. That cap has one practical consequence: you refill more often, and each refill is a moment when the mod is open. Wiping the threads and checking the flap seats properly costs nothing and preserves the rating the mod was chosen for. ## Sealing, knocks and the missing figures The kit is rated IP68, an index defined by standard IEC 60529: complete dust tightness, and resistance to prolonged immersion under conditions stated by the manufacturer. Marketing copy adds resistance to drops and shocks on top of that. Here you have to separate what carries a figure from what does not. For the **Aegis Solo 3**, no immersion depth, no duration and no drop height appear in the sheets consulted, unlike other models in the same family which do quote them. No MIL-STD-810 compliance is claimed anywhere, and the list of electronic protections in the chipset is detailed nowhere. Those points should be treated as undocumented, which is not the same thing as absent. One detail shows how much care a product page deserves: the same listing can quote two slightly different sets of dimensions, in the header and in its own summary table. The gap is minor, but it is a reminder that a figure on a sheet is not a measurement. ## The single cell: what to check on the Aegis Solo 3 One battery simplifies management but excuses no precaution. The cell has to accept the current the mod draws at its ceiling, and that is read on the continuous discharge rating the cell manufacturer publishes for that exact reference, on its own datasheet. That reading is a habit rather than a calculation. You identify the cell by its full code, find the maker's datasheet, and note the continuous discharge current and the maximum charge voltage stated there. Figures relayed on generic packaging or repeated in a forum post are not documentation, and the [nomenclature printed on the wrap](/uk/inr18650-cells/) is where that identification starts. The USB-C port on the mod is described as an occasional top up, not as the main charging route. A [dedicated external charger](/uk/vape-battery-charger/) works in better thermal conditions and manages end of charge bay by bay rather than treating the device as a whole. A visual check of the wrap before every insertion takes two seconds. A nicked sleeve puts the metal can, which sits at the negative pole, in direct contact with the chassis. Between uses the cell travels in a rigid case, never loose alongside keys or coins, and it goes to a battery collection point rather than in household waste at the end of its life. The silicone flap covering the USB-C port also does real work in the sealing claim. Left open or lost, it removes the very characteristic the device was bought for. The same reasoning applies to the battery door, whose seal determines the rating on the box. ## Frequently asked questions ### Can another tank be fitted to the mod? Yes, any atomiser with a 510 connection installs without difficulty. The stated connection diameter sits between 23 and 25 mm, so a wider base will overhang the deck. ### Does a built in battery version exist? British listings carry both an external battery version and a built in cell version of the same mod, which is why the model name alone is not enough when ordering. Check which one a listing describes before buying. ### What VG ratio should be used? It depends on the coil fitted, and the coil packaging states a minimum. Sub ohm mesh coils generally ask for the higher VG liquids, while less aggressive values tolerate thinner ones. ### Is a cell included in the kit? No, the 18650 cell is bought separately. The kit contains the mod, the Z Subohm tank, two coils, a spare glass, a set of spares, a USB cable and the manual. ### What is the Memory setting worth day to day? It saves redialling settings on every atomiser change, up to five configurations kept. It is a convenience feature with no bearing on how safely the device operates. ## Aegis Solo 3: the use case it matches The **Aegis Solo 3** aims at mobile, extended use, with a single cell to watch, an automatic lock suited to transport and a mod light enough to carry all day. The 100 watts available cover the Z Series coils supplied with room to spare, and in UK trim the 2 ml tank is the part that shapes the routine. The undocumented areas, unquoted immersion figures and an unlisted set of electronic protections, are worth knowing before purchase rather than discovering afterwards. A product sheet is read as much for what it does not say, and the same discipline applies to the [dual cell Aegis Legend 5](/uk/aegis-legend-5-mod/) further up the range.
