Lost Vape Therion 166 styling and build quality

I have had my eye on the Therion mods for a while because you only need to take one look at them to see they are highly stylish and elegant devices. Sadly the DNA 75 version wasn’t really something I was that interested since I do on occasion like to vape at high Wattage so when the latest Therion 166 was released I was determined to get one. Funnily enough the Therion 166 actually has a maximum Wattage of 167 Watts but I guess someone at Lost Vape thought 166 sounds catchier than 167. The device comes in an attractive box with a foam inlay and once you take it out you will really admire the high quality of its construction because it feels exceptionally well put together!

The main material used is die cast zinc alloy so it is fairly light but feels much more solid when fitted with batteries. What is remarkable is that it feels perfectly balanced and is extremely comfortable to hold!

You can purchase the Therion in either a silver or black finish and as someone who couldn’t help themself and purchased both I will tell you now that they are both equally gorgeous! The black finished version is highly impressive due to the fact that the finish has held up incredibly well with no signs of wear and actually has some areas with a glossy finish and others matte.

Just to add some more refinement and class to this device it has ebony wood inlay accents on the silver version which looks black until you get it under the light at which point it takes on a dark brown sheen and you can just make out the wood grain. The black version is slightly different and you can get it with mid brown wood inlays or carbon fibre (the version I purchased).

To add even more of a sense of style the magnetic clip style battery door has a beautiful real leather wrap which is available in a variety of styles and colours. What’s more Lost Vape sell individual replacement battery doors so you can really go to town personalising the device to your taste. For my silver Therion I sport an Elephant Black battery door during the day and I like to swap it to the Red Ostrich battery door at night. Obviously no real wild life is harmed in the manufacturing of these covers but if you do happen to come across news reports referring to a decline in the ostrich population then it is likely due to Lost Vape skinning the poor creatures! Joking aside the battery doors look awesome and make this device really stand out from the crowd.

The Therion 166 has three buttons which feel durable, are highly responsive and have a lovely feel to them which means only a light touch is needed. As you might expect given the quality of this device’s construction there is absolutely no rattle at all.

The OLED screen is nicely recessed and is both bright and clear. All of the typical information is shown such as Wattage, Voltage and Resistance as well as Amps, Battery Life and Temperature (when it that mode). In addition the display also shows when the Resistance Lock is enabled and if you don’t like the layout you can personalise exactly what is displayed via use of the EScribe software but you will require access to a computer.

At the top of the device you will find the Stainless Steel 510 connector which has superb and highly durable threading. The connector is secured to the chassis with three Stainless Steel screws and it is completely flush with the top of the device. The 510 pin is spring-loaded and is made from Silver Plated Nickel. The overall size of the connector is about 25mm in diameter so any atomizers up that size will look extremely good on the Therion. The Micro USB port is located on the bottom front of the device and can be used for either charging or connecting to your computer to make use of EScribe.

The battery compartment is nicely set out with the correct battery orientation clearly marked. When you first use the device it can feel a little tricky to fit the first battery because it is a bit of a tight fit but you do quickly get used to it. There is a ribbon fitted to assist with battery removal. The battery contacts are 24K Gold-plated for excellent conductivity.

Now on to something which many people tend to point out about these devices and that is the obvious lack of venting. Now while I would prefer at least a few holes in the base I have to say that this trend we have seen of late regarding a lack of venting has been prevalent in quite a few devices such as the IPV 6X so it is no exclusive to the Therion. What I will point out to you is that the battery compartment uses a very open sled design which allows plenty of air to circulate and there is a slight hardly noticeable gap where the battery door fits which I personally think is more than adequate.

When you also factor in that Evolv’s chip is very efficient I would say that as long as you are using good quality batteries (I use Sony VTC5’s) then you shouldn’t encounter any issues. I have vaped the Therion 166 at 120W using my RDA’s for large amounts of time (basically until the batteries drained) and the compartment itself never really gets that warm. Certainly the top of the device near the atomizer seems to get the warmest but at no point have I ever felt unsafe using this device so the air must certainly be circulating.

Ease of use

Anyone familiar with any device that uses a recent DNA chip will feel right at home here. It is also relatively straightforward for a newcomer to get to grips with and comes with a number of pre-sets, perhaps a few too many Nickel ones for my liking but also Titanium and more importantly to me Stainless Steel 316 so there is absolutely no need to faff around with EScribe if you don’t want to.

  • Five clicks of the main fire button locks/unlocks the device.
  • To lock the power make sure the device is unlocked and hold down the plus and minus adjustment buttons.
  • To lock and unlock the Resistance make sure the device is locked and hold down the fire button and the plus adjustment button simultaneously.
  • To put the device into Stealth Mode make sure the device is locked and hold down the fire button and the minus adjustment button simultaneously.
  • To change the temperature make sure the device is locked and then hold down the plus and minus buttons simultaneously. The temperature can be adjusted in the menu and you can have it display in either Celsius or Fahrenheit or switch it off completely.
  • o access the pre-sets on the device make sure the device is unlocked then hold down the plus and minus buttons to access power mode and then click the plus button a couple of times. The device pre-sets include Wattage Mode, Ni200, Ni200 No Preheat, Ni200 Relaxed, SS 316 and Titanium.

Lost Vape Therion 166 performance

The device works brilliantly whether you choose to use Variable Wattage or Temperature Control. I’ve used loads of my RTA’s on this device including my Rose3, my Tilemahos V2 Plus, my Kayfun 5 and also my Phenomenon Lite. I have always had a consistent and enjoyable vape with each of them. Even when using my Goon and Apocalypse RDA’s at high Wattage the vape quality of this device has always been excellent!

Temperature Control mode works flawlessly and offers a fantastic vaping experience with no heat spiking or temperature fluctuation and the Resistance Lock works extremely well. Battery life is fairly typical of a dual 18650 device (perhaps a little more efficient) and will depend on your Wattage and how often you vape.


Stylish with an exceptional build quality the Therion 166 is a truly exceptional product and one that offers a wide variety of styles as well as the unique option to buy entirely different battery doors.

I love this device so much I ended up getting two of them, one black and one sliver because they really are something special. As you might expect given my job I do have a fair few devices on my shelf but funnily enough the Therion seems to be the one thing I always grab first when I want to vape because it really does feel that good to use. The only real negative to the Therion 166 is that it certainly doesn’t come cheap but the great build quality, elegant looks and the flawless performance make this well worth the asking price!

You can purchase the Therion 166 from a variety of UK vendors. I purchased my silver Therion 166 from Grey Haze and you can get it directly from them. Remember to use code POTV10 for 10% off your purchase.
