Lost Vape Thelema Solo | Faults, Warnings and Warranty

A warning flashing on the screen, a mod that stays dark after five presses, vapour that runs out of steam halfway through a puff. With the Lost Vape Thelema Solo, these issues can appear after a few weeks, once the battery has aged or the connector has gathered grime. Shop listings detail the Quest 2.0 chip, yet none of those checked explains what to do when it refuses to fire. A few checks come before any return, in a set order.

Lost Vape Thelema Solo not working, where do you start?

A Lost Vape Thelema Solo that plays up is best sorted in this order. Read the message on the screen first, then check the battery (charge, orientation, condition of the wrap), then the 510 connector and the coil. The warranty comes after those three steps, since most warnings below point to the battery or the atomiser.

This method covers the Thelema Solo 100W. The 100 Pro, common in search results, is a different model whose menus may not match.

Symptom	Most likely cause	First step
Low battery warning	Flat, badly fitted or tired cell	Recharge, check orientation, try another cell
Short circuit or atomiser warning	Dirty 510 pin, loose or damaged coil	Clean both connectors, retighten, change the coil
Overheat warning	Device too hot after long use	Switch off, remove the cell, wait 30 minutes
Wrong coil reading	Poor contact or damaged coil	Clean, retighten, compare with another coil
Mod will not switch on	Flat cell or dirty contacts	Clean the contacts, charge for at least an hour
Power fading	Cell nearly empty or too weak on current	Switch to a charged high-drain cell

What do the screen warnings mean?

The Lost Vape support FAQ, written for the brand’s whole range rather than the Solo alone, explains what each warning points to and what to do, and the exact wording may vary between devices.

Low Battery

This message means the cell is too flat to fire. The manufacturer advises recharging it with the correct cable, or in a suitable external charger. If the warning stays with a full cell, check the polarity and the battery bay contacts, then try a different cell.

Short Circuit and Check Atomizer, the problem sits on top

Both messages point at the atomiser. The first step is to clean and dry the 510 pin on the mod and on the tank. If nothing changes, reseat the coil, try a new one, tighten the tank, then test another atomiser to see which part is at fault.

The overheat warning

After long use, that FAQ says, the device or tank gets too hot, an overheat protection shows and the mod stops firing. Lost Vape then asks you to switch it off, remove the cell and leave it for 30 minutes. For a tank that runs too hot, the same FAQ advises lower wattage and no chain vaping.

Why does the coil reading differ from the value on the coil?

The chip in the Lost Vape Thelema Solo reads the atomiser’s resistance and shows it on screen. The manufacturer’s spec sheet gives an accepted range of 0.15 to 5 ohms.

In its January 2022 review, the UK site Ecigclick measured 0.18 ohm on a UB Pro P1 coil sold as 0.15 ohm. The mod shows what its chip measures, which can differ from the value printed on the box.

A large gap, or a value that jumps from one puff to the next, points to a poor contact instead. Clean both 510 connectors, refit the tank without forcing it and compare with another coil. A reading that settles points to the previous coil, as can happen with Geekvape coils or any head near the end of its life.

The mod will not switch on or will not charge

These two faults get mixed up, yet a dark mod lacks power or contact, while one that will not charge usually has a cable or port problem.

A mod that stays dark

Clean the battery bay contacts, then try the five quick presses on the fire button again. The manufacturer then recommends charging for at least an hour with the recommended adapter, and testing that charger on another device. According to the spec sheet, the battery voltage range is 3.0 to 4.2V, so a cell below 3.0V falls outside it.

Charging that will not start

The mod’s USB-C port runs at 5V, and the battery icon animates while charging, then stops once the cell is full. If nothing happens, clean the port and plug, then try another cable and charger. A separate vape battery charger shows simply whether the fault lies with the mod or the cell.

Power fading, is the Thelema Solo battery to blame?

In its March 2022 review, the French site Vaping Post noted a lack of power beyond 70W as the cell drains. At those settings, the mod asks a single cell for a great deal of current.

On a Lost Vape Thelema Solo, the answer lies with the battery. Lost Vape’s FAQ advises against sub-ohm vaping without a high-drain cell rated above 25A, to be kept charged and swapped once the power drops. Our 21700 battery guide explains how to read a cell’s spec sheet.

That review also noted the lack of venting holes, a reason to fit only cells with an undamaged wrap.

A loose battery door and a trim to replace, fault or normal?

The battery door is held by two small magnets, according to the UK review mentioned earlier. The French review still found slight sideways play, and a buyer describes the same clicking under a retailer listing. In reply, the retailer says the fit varies between units and suggests squeezing the back of the mod in the palm to tighten the sides.

As for the leather trim, the same retailer says the cover is not sold on its own, but the existing trim can be peeled off and replaced with another. Play that annoys without stopping the mod working is a comfort issue, not a fault.

When should you use the Lost Vape warranty?

Lost Vape covers its mods and pod kits for 3 months from the purchase date on the invoice. Consumables (tanks, coils, O-rings, glass) are excluded, as is damage from misuse or modification.

For a Lost Vape Thelema Solo bought less than three months ago, gather the proof of purchase, clear photos of the serial number and security code, and a photo or video of the problem. The manufacturer asks you to contact the retailer first, then its support team if the retailer cannot handle the claim. Beyond three months, Lost Vape’s warranty no longer covers the device, and the retailer is still the one to ask.

FAQ

These questions come up among owners of the mod, outside the faults themselves.

How do you unlock a Thelema Solo whose wattage will not move?

The plus and minus buttons are most likely locked. According to the UK review mentioned earlier, pressing and holding both buttons together works that lock. On this chip, you also need to select a setting with the middle button before you can change it.

Which coil suits the Thelema Solo?

The manufacturer pairs the mod with UB Pro coils, the 0.15 ohm P1 at 70 to 90W and the 0.3 ohm P3 at 60 to 70W. One retailer also sells it as a kit with a Centaurus tank and UB Max coils at 0.15 and 0.3 ohm.

Can you restore the factory settings?

Yes. The French review mentioned earlier refers to resetting the chip to its factory configuration. Noting the three presets beforehand lets you restore them if they are wiped.

Can the puff counter be reset to zero?

Yes. According to the UK review, you move to the counter with the plus and minus buttons, then press the middle button to clear it.

Should you buy the mod on its own or as a kit?

It depends on the tank you already own. The mod on its own needs a 510 atomiser that copes with its 100W. A kit saves hunting for a compatible coil, but its contents vary by retailer, so check which tank comes in the box before ordering. In the UK, refillable tanks are capped at 2ml, which is the version to look for.

Lost Vape Thelema Solo, troubleshoot in order before sending it back

Each profile has its own first check. A vaper new to box mods looks at the battery and its charge first, a high-wattage sub-ohm vaper at the cell’s discharge rating, and a recent buyer with a genuine fault keeps the invoice and photographs the serial number within three months.

A Lost Vape Thelema Solo showing a warning is not necessarily broken. Message read, battery checked, connectors cleaned, coil changed, many cases end there, and the same method works for an AIO mod as for any battery-powered vape.
