Lost Vape is responsible for some of the best looking, and best performing vape devices around. Although they’re best known for their dual battery DNA box mods like the Centaurus DNA 250C and their Orion line of pod vapes, they’ve been steadily producing single battery mods too. Most recently we reviewed the Cyborg Quest mod and Centaurus Quest squonk mod — two great additions to their lineup.

The newest single battery mod from Lost Vape is the Thelema Solo. It’s the single battery version of their Thelema Quest mod and it features a similar design and set of features, just in a more compact device. The Thelema Solo takes a single 21700 or 18650 battery and can output up to 100W. The kit comes with the UB Pro Pod tank which is the same tank that is included with the Thelema Quest kit.

This device was sent to me by Lost Vape for the purpose of this review. However, this does not in any way affect my opinions or ratings of the device.

Design & Build Quality

  • Lost Vape Thelema Solo 5

The Thelema Solo is a nice little single battery mod. It looks just like the Thelema Quest dual battery mod, just less deep due to only taking a single battery. Otherwise, the Thelema Solo is very similar in height and width and pretty average in terms of size for a single 21700 mod.

The design of this mod is really nice. The majority of the available color options come with carbon-fiber-like accents and a carbon fiber leather pattern on the battery door, but there is also a black leather, orange leather, and aquamarine leather battery door available. The frame of the device is made of zinc-alloy and comes in one of five colors: red, blue, black, gunmetal, or silver.

The carbon fiber leather grip on my unit is solid and not soft at all. It doesn’t squish like you might expect but it feels nice and I like the look too. The battery door slides on and off and can be attached either way up. The magnets are very strong and hold the battery door snug and in place. You can use either a single 21700, 20700, or 18650 battery in the Thelema Solo. It’s a good fit with a spring loaded contact that holds the battery in place well. 

Branding is kept to a minimum and there is only LOST VAPE on one side of the mod, and THELEMA SOLO on the other side. It’s a clean looking mod and maybe one of my favorite looking single battery mods to come out recently. The build quality is overall very good, although the paint seems to be a weak point. Some of the paint around the edges of my mod has started to show minor wear. Otherwise, the fit of the battery door is excellent, and the machining is excellent. 

The Thelema Solo is a great looking mod with good build quality, let down only by the fading of the paint.

UB Pro Pod Tank

The Thelema Solo kit comes with the UB Pro Pod Tank, which is the same tank that is included with the Thelema Quest Kit. It also comes with the same coils. If you’re interested in reading about this tank, check out Adam’s review of the UB Pro Pod Tank here.

Lost Vape Thelema Solo Features

Lost Vape Thelema Solo Screen

The Thelema Solo is no DNA mod, but it still comes with a ton of features that you would expect from a modern single battery mod. It houses Lost Vape’s Quest 2.0 chip which will allow it to fire at up to 100W in power mode, and from 200°F to 600°F in TC modes. The following modes are available on the Thelema Solo: Power mode, TC modes (nickel, titanium, SS316L, and SS904), Bypass mode, Voltage mode, and Custom Wattage Curves. Sadly, there isn’t a way to adjust the TCR value for each material so you’re stuck with the values it uses.

As far as the user interface goes, it’s intuitive and simple to navigate. The screen is 0.96” in size and it’s bright and in full color. There are three buttons on the face of the Thelema Solo that you can use to change modes or settings, with the middle button being the ‘select’ button. You just have to use the up and down buttons to hover over the option that you want to change, then hit select to pick it, then again use the up or down buttons to change it.

As an example, if you want to change from power mode to one of the other modes, you would use the up and down buttons until you’re hovering over ‘Power’. Then you would use the select button to select it, and then again use the up or down adjustment buttons to switch through the modes. Once you’re in the mode that you want, you can press the select button again and the mode is changed.

The menu option at the bottom of the screen will, of course, open the menu. There isn’t much of note, but you can use the atomizer option to remeasure your coil resistance if it’s not reading correctly (a rarity with this mod), or adjust the wattage or temperature too. 

Other options in the menu let you change the screen brightness, the color of the UI, reset all the settings, or set user profiles. You can set 3 profiles which can be quickly selected from the main menu. For example, you can set the first profile for temperature control at a specific wattage and temperature, and profile 2 for wattage mode at specific wattage and hardness (soft, normal, or hard). This lets you quickly go from TC to wattage mode without having to manually adjust the settings each time.

Lost Vape Thelema Solo Button Combinations

  • Turn device off or on: Press fire button 5 consecutive times
  • Lock/Unlock adjustment buttons: Hold select +/- buttons together
  • Reset puff counter: Use adjustment buttons to highlight the puff counter. Press select to reset.
  • Change vaping mode: Use the adjustment buttons to highlight the mode and then press select. Use “+/-“ buttons to switch between modes. Press select again when you are in your desired mode.
  • Adjust temperature or watts: Highlight the temperature or wattage on the UI. Press select. Use “+/-“ buttons to adjust.


Lost Vape Thelema Solo 6

The Thelema Solo is a great performer for power mode. This shouldn’t be too surprising though if you look at Lost Vape’s track record. It’s good all the way up to 100W and outputs reliable, accurate power whenever I hit the power button. It’s also a good mod at detecting the coil resistance; very rarely did it differ from my ohm’s reader when I used an RDA, or from the premade coil when I used a subohm tank. 

Battery efficiency is as good as any other single battery mod, but a single battery does not get you far when you’re vaping at 80W+ like I was. This is the truth of a single battery mod and so the Thelema Solo is better from the 0.30Ω coil if you’re using the UB Pro Pod tank that comes with the kit, or for higher resistance coils in general if you’re using anything else. 

The TC Mode performance is good, but hindered by the lack of TCR value adjustment. I think that it’s perfectly fine for vaping in temperature control if you’re just testing it out or if you occasionally use TC mode, but for hardcore temperature control enthusiasts you will want to get a mod with a DNA chip for the best possible experience.


I love the Thelema Solo. It’s another great mod from Lost Vape that hits all the right areas that the typical vaper is looking for: a nice design, easy to use UI, and great power mode performance. While it’s not the best TC mode mod, it is passable and definitely good enough for occasional use when you have a coil that is capable of TC.

The mod by itself is definitely worth the purchase. I think that the kit is also worth grabbing if you’re looking for an upgrade to your tank and don’t want to purchase a whole separate tank. 

When you take it all in, the Thelema Solo mod or the kit are both excellent buys for anyone who is after a great single 21700 mod.
