The Techy Bit
Tegstove uses a Thermoelectric Generator (TEG) to produce an electrical current.
TEGs are two ceramic plates with the connection between the two plates made up of two different materials. They have a hot and a cold side. When a difference in temperature is applied between the two sides an electrical current is produced. The greater the temperature difference the more power it produces.
TEG technology is not new, but the ability to harness its power has never been fully utilised …until now.
Tegstove portable gas camping stove uses an innovative method to create an even greater temperature difference, resulting in more electrical energy production. This method produces a stable, constant and controlled source of warmth to the cylinder ensuring constant gas pressure is maintained.
A little bit of history
TEG technology has been around since 1821. But its low power output meant that it was relatively unusable at the time as technology was not efficient enough to take advantage of it. Over the years, electrical devices have become more efficient and we can now take full advantage of the Thermoelectric Generator and the brilliant work carried out by Thomas Johann Seebeck, 200 years later.
Why is TegStove different?
Many TEG based products have concentrated on the supply of heat to the hot side of the TEG.
Cooling the cold side is more difficult.
Often water is used, however the cooling effect is reduced as the water temperature increases plus you need to keep adding water as it evaporates.
Another option is to use a fan to remove the heat, the more heat you need to move the more energy the fan needs and the louder it becomes.
This is where Tegstove’s patent pending design sets itself apart.
Tegstove transfers the “cold” produced in the cylinder to the chassis, as the heat sink gets hot the heat is drawn towards the cold of the chassis, helping the heat sink to dissipate the heat, this reduces the amount of work the fan needs to do.
The cooling effect produced by the cylinder is as constant as the heat from the burner. Using this method creates a greater temperature difference – resulting in more electrical energy production and less energy required by the fan.
Another problem with your average gas stove is the liquid gas in the cylinder requires warmth to change from it’s liquid state to a vapour, if the cylinder gets too cold the liquid gas stays as a liquid and this results in low gas pressure. This is why you will often see the flame reduce after a few minutes on a standard stove. The colder the cylinder gets the lower the pressure gets. To combat this, camping stoves often use a mix of gases that will work in a wider range of temperatures (propane/butane/isobutane) – but this is not a perfect solution. When these mixed gas solutions get too cold the propane burns off first leaving the butane behind, the butane is wasted unless the cylinder is warmed, mix gas cylinders also cost around three times more than the butane.
Tegstove’s design not only draws the cold away from the cylinder but we also push warm air from the heat sink into the chassis and air surrounding the cylinder, this system inhibits the cylinder getting too cold and this results in higher working gas pressures.
Powerful charging system that (unlike a solar panel) will charge your devices day/night in cloudy conditions and under the tree canopy – if you don’t need to charge anything when your cooking on the stove, that ok to as all the spare energy produced by the Thermoelectric Generator is stored in a 3000 mAh battery for use when you really need it.
Tegstove is far more cost efficient to run than conventional portable gas stoves that run on mixed gases, it’s very stable, well built and incorporates a powerful charging system to keep your mobile phone, GPS, tablets, USB lights, portable speakers and Go-pro’s running.
This is why Tegstove is possibly the best portable gas camping stove on the market today.
The colder the cylinder gets the lower the pressure gets. To combat this, camping stoves use a mix of gases that will work in a wider range of temperatures – but this is not the perfect solution. When they get too cold the propane burns off first leaving the butane behind, the butane is wasted unless the cylinder is warmed also the mix gas cylinder cost on average three times more than the same amount of butane.

Is this the most energy efficient gas stove in the world?
Tegstove uses widely available, cost-effective, clean-burning butane gas
Standard camping stoves will often use a mix of Butane, Propane and Isobutane to create a gas that works in cold climates. This is an unstable and expensive method.
Butane is better gas – it comes in lighter cylinders, it can be stored inside, it’s more cost-effective, less volatile and readily available.
But it gets cold fast and the pressure reduces.
Tegstove have taken this ‘problem’ and turned it into a benefit.
The cold produced by the cylinder is used to help cool the cold side of the TEG – creating a greater difference in temperature between the hot and cold plates. The result? A strong controlled flame and stable production of electricity.
The design team at Tegstove wanted to create a better camping stove. One that eliminated all the usual frustrations, and ticked off every feature on their wish list. So whether you’re camping, fishing, kayaking or preparing a survival kit you have an “all in one” device that is efficient, reliable, portable and safe.
One single unit – Gas stove, portable charger, battery pack and gas cylinder all in one. The beauty of the Tegstove design means it’s portable, space-saving and efficient.
Stability – Three adjustable legs provide a stable platform and cover over 300mm of ground, so no toppling over. You can sit comfortably in your camping chair and use your Tegstove at the perfect height so no more muddy knees.
Charging – Add power to your devices at any time – not just when you’re using the stove for cooking. If you wish to charge while your cooking you can and the USB connection is located at the base of the battery pack keeping your Tech away from the heat. A simple feature for safety and convenience.
Safety – Tegstove have designed and incorporated their own gas pressure shut off system – completely mechanical with no electrical parts at all. Safety was a top consideration during the design process, Tegstove conforms to both Ce & CSA standards.
Cooking – Prepare real meals. Heat is distributed over a wide cooking area so you won’t just burn everything in the middle of the pan. A common issue with butane gas stoves is that they fail during longer periods of use due to “cylinder freeze”. Tegstove will not suffer the same fate! You can cook hearty family meals with plenty of heat when you need it even when the cylinder content is low.
Looks – Determined to think differently, the team worked tirelessly to achieve the best possible design for the Tegstove. The brief – control the gas, give a stable base, provide a way of charging devices and get everything off the ground with all the associated risks reduced to the lowest level possible. And that’s exactly what we did.
Do you need to pre-charge the internal battery?
No – It will begin charging the internal battery when you light it, but you can pre charge the internal battery via the micro USB port if you wish.
Do I have to light the stove to charge stuff?
No – Whenever you light it the Tegstove will start charging the internal battery, you can use the energy in the battery whenever you want it. All the energy in the battery is for charging your tech; none is saved for the stove at all not even a little bit.
What’s wrong with the mix gas solution?
The mix gas cylinders contain Propane and this is more volatile and produces higher pressures than Butane, because of this the cylinder needs to be stronger and as a result is heavier, mix gas cylinders are typically three times more expensive than the equivalent amount of butane.
Can I get a different colour?
Not at the moment, but we may bring out different colours in the future.
Can I charge whilst I cook?
Yes – but you don’t have to, you can charge stuff whenever you want to.
Will it charge my iPad or Android tablet?
Yes it can – the stove will charge devices at a rate of 5 volts up to 1 amp (tested with iPad air 2)
Will it charge my phone from empty to 100 percent?
Yes it will – Mobile phones have various sizes of internal batteries, so charge time will vary.
Is it safe?
The stove is tested independently and conforms to both CE and CSA standards; we have designed our own patent pending pressure safety system that ensures the stove exceeds these standards.
What's the weight?
The weight is 1.4kg – lighter and smaller than the total weight and size of individual items needed to cook, charge and store energy.
Where can I get the gas?
The Butane cylinder conforms to EN417 standards, it’s available in many countries and has a universal fitting. Available at many camping stores, hardware stores, fishing tackle shops as well as high street chains like Liberty Mountain, Cotswolds Outdoor, Walmart, Go-Outdoors and Decathlon to name just a few.
Why is the copper part black already, it looks like it has already been used?
Every stove is fully tested before shipping to ensure everything’s working, to do this each stove is lit and run to full temperature and the copper top discolours.
When I light the stove the flame flares up for a few seconds, why is this?
The gas cylinders have a small tube inside, during transit the tube can fill with a little liquid gas. When you connect the cylinder to the stove this small amount of liquid gas heads to the burner and ignites causing the flame to flare up, to avoid this you can purge this liquid by allowing a small amount of gas to vent through the stove before you light it. If you do this please ensure you allow a few minutes for the gas to dissipate before you try to light the stove.
What about warranty?
The stove is covered by a standard 1-year limited warranty – if you don’t mistreat it and it fails due to a manufacture fault, send it to us and we will fix it or replace it.
