The Uwell Soulkeeper is an unregulated mech mod that has 18650, 20700 and 21700 capability. The Soulkeeper is not a full mech mod because of the safety chip installed in its all-brass frame. The chip does not regulate power.
What it does do is use an electronic switch to make contact between the button and the negative side of the cell. This reduces the chances of battery degradation, or the possibility of arcing that preserves both the battery and the device. The all-brass frame of the 93.5mm long (3.68 inches) Soulkeeper comes in either all-black, all-white and fluorescent.

Uwell Soulkeeper Mod Review: The First Look
The Uwell Soulkeeper semi-mech mod is a simple-looking device. It measures under 4 inches long and has a diameter of 25.6mm (1”) that is wide enough to take 24mm diameter RBAs or tanks without any overhang. One end of the Soulkeeper tube features the stainless steel 510-connection, while the other end sports the “Uwell” branded firing switch.
Within the “Uwell” logo on the switch are two pin-sized air holes for the battery to vent. The switch has an electronic switch beneath it, so when users depress it, the button “clicks” like it would with a regulated mod’s firing button. The button-click is a part of the Soulkeeper’s unique design.
The Soulkeeper features a chip within that acts as a safety barrier. It prevents arcing, which comes from repeated contact between the switch and the negative side of the battery. This electronic switch is not the only innovation users can find on the Soulkeeper.
The mod works with multiple battery types, like 18650, 20700, 21700. This versatility in itself is not something new, but the way the Soulkeeper does it is unique. Other multi-battery mods use a separate, plastic or Delrin insert that users either have to put into the mod or remove it or it comes already inside the mod’s build.
The Soulkeeper also has the latter, but those other mods use the sleeve to make a 20700 or 21700 device 18650-compatible. The Delrin sleeve inside the Soulkeeper does the reverse – it makes the mod compatible with 20700 and 21700 batteries as it comes from the factory ready to take only 18650 batteries.
The way that the Soulkeeper does this is simple. Users need to unscrew the firing switch, and then the 510-connection. Then they switch them around by putting the firing switch on the opposite end, and the 510-connection where the firing switch was, and then – bingo, bango – the mod can take 20700 or 21700 cells.
The switching of the two ends adds to the mod’s length so that it can take the larger-sized batteries — nothing else about the mod changes. There is also a small LED light on the lip of the firing switch that signals battery life:
- green = full,
- blue = half,
- red = recharge.
The Uwell Soulkeeper comes in a sleeved box that features all three color options on the front. Vapers need only remove the sleeve to access the box, and lift open the top. Inside they will find the following:
- One Soulkeeper mod
- One user manual
- One battery safety card
- One warning card
- One instruction card (Fluorescent model only)
Getting the Mod to Work
The Soulkeeper Mod is all-brass. The 510-connection features some knurling around its edges and is stainless steel.
The inner battery sleeve along with the coating under the switch is Delrin and acts as the device’s protection against battery shorts. The chip inside the firing switch also protects against short circuits, open circuits, low voltage, overtime usage, and reverse battery protection.
Of course, the mod does this independent of usage, so a user does not have to activate or turn on these features. There’s not much else to get the Soulkeeper to work other than installing a battery of your choice, attaching a tank or RDA and vaping.
Vaping the Uwell Soulkeeper
The Soulkeeper has a 510-connection, but it is not a hybrid one so that vapers can attach 510-threaded sub-ohm tanks to the mod. With high-capacity 21700 or 20700 cells inside the Soulkeeper, the maximum possible power output hovers around 110W, according to most tests.
No word yet on what the output is with a 18650 cell, but the smaller-capacity batteries usually top out at around 90W. But, again, no matter the type of battery, the mod can take both RBAs and sub-ohm atomizers.
With the unlimited power of the cell, the device fires immediately, but the coils inside the atomizer also make a difference. There’s no listed resistance range for the Soulkeeper so there’s no real way to know how low it can fire, but it should be on par with normal ranges that start at around 0.08ohms.
The Vape-Off: A Look at the Competition
The Acrohm Fush Protected Mod
The Acrohm Fush protected mod is a single 18650, semi-mechanical mod, as it too carries a chip, the Ace chip, within its stainless steel and polycarbonate frame.
The outside of the Fush also holds LED lights that can flash in several colors. A user can toggle through the five different colors by shaking the mod. The Acrohm Fush is 110mm (4.3 inches) tall and has a diameter of 26mm but expands to 28mm at the base. The firing switch on the device has gold-plated contacts and uses five-clicks to turn on, as well as to fire.
Acrohm Fush Mechanical Mod
The VAMP Rig mechanical mod measures 87.3mm (3.43 inches) tall and 25mm in diameter (0.98 inches). It is a single 18650 device with an all-copper build, with stainless steel threads. The switch is spring-loaded and comes as either copper or brass.
The VAMP Rig has a 510 hybrid connection so users should only use atomizers with a protruding 510-pin to avoid the positive pin from coming in contact with the negative side of the battery. For further battery protection, the Rig also has Delrin insulators and battery venting holes.

Final Thoughts on the Uwell Soulkeeper
The Uwell Soulkeeper is a unique, beautifully-made semi-mechanical mod. The fact that it can use several battery types is one draw, and the way it achieves this feat is also remarkable. By only switching the firing switch with the 510-connection, the mod then becomes 20700 or 21700 compatible.
The exterior design of the Soulkeeper is also impressive. It goes from solid-white to solid-black to fluorescent, the latter of which has a wild, chaotic inlay of a dragon and lights up in the dark. Mech mod makers do not have much of an option in designing their mods, but the flat, featureless design of the white and black versions is stunning in its simplicity.
The addition of a safety chip to protect against common mech mod problems is for people who want that extra blanket of security when using an unregulated device. The Soulkeeper is not a full, mech-mod, and it is the first device of its kind from Uwell. They seemed to want to attract people from both sides, mech mod, as well as box mod vapers, and they have done an excellent job with the Soulkeeper.

how does the soulkeeper regulate the power? is it by restricting amps or voltage? if its by amps than according to P = U * I the max amps i should get out of my battery is 26 amps, if it’s by voltage, it’s a different thing. any thoughts on that?
