The best Peltier elements, compared.
Top pick: Diymore TEC1-04902 five-pack Best value: Diymore TEC1-12706 two-pack – About £7.99 for two TEC1-12706 tiles, 4.4 from 249 reviews, score 88. The cheaper DollaTek pair failed within minutes in one test at or below 7 V. Updated October 2026.
A Peltier element is a thermoelectric module for a repair or a bench project. Apply direct current and a cooler tile pumps heat from one ceramic face to the other. A generator tile makes a small voltage from a temperature difference. On amazon.co.uk the usual jobs are a 12 V cool-box spare, a heat-powered stove fan, or a small insulated cooler. Match the voltage and current class, and give the hot side a sink that can reject the pumped heat plus the electrical input. A plate a few millimetres thick is the module. A USB port will not run a 12 V cooler that draws several amps. A mains adapter needs a BS 1363 plug. The printed watt figure is the heat pumped near zero temperature difference. The [Peltier element stove fan](/hub/electrical-equipment/peltier-element/sub/peltier-element-stove-fan) guide covers when a generic plate is a fair spare for a heat-powered fan. The Electrical Equipment (Safety) Regulations 2016 apply from 75 V DC. These tiles are judged under the General Product Safety Regulations 2005. Power without a sink can destroy the tile.

Personal buying guide
Question 1 of 2
What are you fitting?
The diymore five-pack is five TEC1-04902 modules at about £9.98, about 20 × 20 × 4.0 mm, with the title stating 5 V, 5 A and 10 W and a bullet stating a maximum temperature difference of 60°C. The star line is 5.0 from two reviews. The stored score is 100, and that sample is too small for a category award. One buyer measured about 20 mm square and about 3.5–3.7 mm thick, close to the bullet, and at 5 V reported about 1 A. The same note calls the tiles too small to use without extra paste and heatsinks, and the box is a manual only. The material field says copper, which does not describe a whole ceramic module. This is the 5 V class in the set. A 40 mm TEC1-12706 is a different part, and a small experiment still needs a sink before you leave the tile powered.
Pros
Cons
Best for: You need a 5 V, 20 mm tile for a small experiment and you will add paste and a sink.
Less suitable: A 12 V cool box or a stove-fan base that expects a 40 mm TEC1-12706.
Specifications
Common questions
What thermoelectric part is in this listing?
The listing identifies TEC1-04902. The pack is five modules, about 20 × 20 × 4.0 mm. The title states 5 V, 5 A and 10 W.
Does the box include a heatsink or fan?
No. The box is a manual only. A captured review says paste and heatsinks are still required.
What do the captured reviews repeat?
One buyer measured about 20 mm square and about 3.5–3.7 mm thick. At 5 V the same review reported about 1 A. The star line is 5.0 from two reviews.
ALAMSCN sells two TEC1-12706 modules and two 40 × 40 × 11 mm aluminium sinks at about £8.96, with wires of 28 cm and an assembly pressure of 85 N/cm². The star line is 4.6 from only six reviews, so the stored score of 92 stays off the award. Cooling power is listed at 60 W and Imax at 6 A, and the page tells you to add thermal paste, which is absent from the package line. One captured use chilled a 60 litre aquarium in hot weather only after the buyer fitted larger graphics-card heatsinks and a PC power supply. The included sinks were left unused for that job. A seller note for a 40 × 40 × 11 mm sink puts that size at a few watts. The number-of-items field says 1 while the title says two modules and two sinks.
Pros
Cons
Best for: You want two tiles and two small aluminium plates in one parcel and you will keep the current well below 6 A on those plates.
Less suitable: A 60 litre tank, or any full-current cooler that needs a large hot-side sink.

Common questions
What thermoelectric part is in this listing?
The listing identifies TEC1-12706, with cooling power listed at 60 W, Imax 6 A, wires of 28 cm and an assembly pressure of 85 N/cm².
Does the box include a heatsink or fan?
Two 40 × 40 × 11 mm aluminium sinks. No fan is listed. Thermal paste is not in the package line.
What do the captured reviews repeat?
One use chilled a 60 litre aquarium only with larger graphics-card heatsinks and a PC power supply. The included sinks were not used for that job. The star line is 4.6 from six reviews.
The diymore five-pack is five TEC1-12706 plates, each listed at 40 × 40 × 3.6 mm, for about £15.58 on amazon.co.uk. Across 450 ratings the line is 4.4, the largest sample in this set, and captured reviews describe the tiles as matching the advert for small projects and as a replacement element in a wood-burner fan. One UK test at 12 V drew about 3.5 A, which that reviewer treated as about 40 W rather than the 60 W and 6 A title. The box lists a manual only, so you still buy paste and a hot-side sink. Qcmax of 50–60 W is the figure near zero temperature difference, and the cooling you measure in a box is a separate, smaller result. The listing’s −30°C to 70°C line is an operating range for the module. Vmax is printed as 15 V, so a car system sitting near 14 V has little headroom if you run the tile hard. It is the top pick for several spare 40 mm tiles when the sink is already in the appliance or on the bench.
Pros
Cons
Best for: You want several spare 40 mm TEC1-12706 tiles and you already have a sink in the appliance or on the bench.
Less suitable: A first kit where you expected a fan and a sink in the parcel, or a 5 V project fed from USB.
Specifications
Common questions
What thermoelectric part is in this listing?
The listing identifies TEC1-12706. The pack is five modules. Listed output is Qcmax 50–60 W and Imax 6 A.
Does the box include a heatsink or fan?
No. The box lists a manual only. You add paste and a hot-side sink.
What do the captured reviews repeat?
Reviews describe the tiles as matching the advert for small projects, and as a replacement in a wood-burner fan. One UK test at 12 V drew about 3.5 A.
This diymore pair is two TEC1-12706 modules at about £7.99, the same 40 × 40 × 3.6 mm class, with a stated Qcmax of 50–60 W. The star line is 4.4 from 249 reviews. Captured notes use the tiles as a stove-fan and log-burner fan spare, and to repair coolers and a cool box once thermal paste was added. One of two tiles arrived cracked at a corner, so you should inspect the ceramic before you clamp it. A bullet prints Vmax as 15A, which reads as a listing error on a voltage field rather than a 15 A current rating. The package line is a manual only, with no heatsink and no paste. Cash outlay is about £7.99 for two tiles, about £4.00 each, which is a higher price per tile than the five-pack at about £3.12. It is the best value when you need two tiles and you will check the ceramic.
Pros
Cons
Best for: You need two 12 V TEC1-12706 spares and you will check the ceramic for cracks before you fit paste.
Less suitable: A stove fan whose maker sells its own generator module, or a job that needs a sink in the same parcel.

Common questions
What thermoelectric part is in this listing?
The listing identifies TEC1-12706. The pack is two modules. Listed output is Qcmax 50–60 W and Imax 6 A.
Does the box include a heatsink or fan?

Notes use the tiles as a stove-fan and log-burner fan spare, and to repair a cool box with paste added. One of two tiles arrived cracked at a corner.
The diymore paste bundle is two TEC1-12706 modules plus 5 g of HY810 paste, listed with thermal conductivity above 4.6 W/m·K, at about £8.99. Stars are 4.3 from 190 reviews. Captured notes say it worked on a DIY project and repaired a stove fan, and one buyer had to add spade connectors that were not in the box. The heatsink-size bullet of 40 × 40 × 3.6 mm matches the module, so the paste does not arrive with a finned sink. The listing also prints 4.3–4.6 A at 12 V beside an Imax of 6 A and a Qcmax of 50–60 W. You still prove which face is cold at low voltage with a sink fitted, because guides disagree about the printed side. At about a pound more than the bare £7.99 pair you are paying for a small tube of paste.
Pros
Cons
Best for: You already own a heatsink and you want a small tube of paste with two 40 mm tiles.
Less suitable: You read the 40 mm line as a finned sink, or you need leads that already end in spade connectors.

Common questions
What thermoelectric part is in this listing?
The listing identifies TEC1-12706, two modules, with Qcmax 50–60 W, Imax 6 A, and a line of 4.3–4.6 A at 12 V.
Does the box include a heatsink or fan?
It includes 5 g of HY810 paste. The 40 × 40 × 3.6 mm heatsink bullet matches the module. A separate sink is not listed.
What do the captured reviews repeat?
Notes say it worked on a DIY project and repaired a stove fan. One buyer had to add spade connectors that were not in the box.
The Youmile pair is two TEC1-12705 modules at about £9.29, 40 × 40 mm, on 12 V with Umax 15.4 V and Imax 5 A. The title says 45 W and a bullet says Qmax 77 W, so the watt lines disagree. Leads are listed at about 300 mm, and the page says the face marked TEC1-12705 is the cooling side. Stars are 4.3 from 27 reviews. Captured notes report a fix for a faulty cool box and a short UK comment that the item was good, and no UK review in the file describes a failure of this ASIN. Twenty-seven ratings is a thin sample beside the TEC1-12706 pairs that carry 190 to 450 reviews. A silicone heatsink is named in the title only, and paste is absent. Treat it as a 5 A, 40 mm spare when the old tile is a 12705. A 6 A TEC1-12706 is a different current class even when the square matches. The marked-face line on this page still wants a low-voltage check, because other mounting guides disagree.
Pros
Cons
Best for: Your cool box already uses a 40 mm TEC1-12705 and you want a spare pair with leads.
Less suitable: A 6 A TEC1-12706 job, or a project that needs a finned sink in the same parcel.

The DollaTek pair is two TEC1-12706 tiles at about £5.99, listed at 40 × 40 × 3.75 mm with an internal resistance of 2.1–2.4 ohm. The specification bullets do not state a supply voltage, and the performance line is a delta-T max above 59°C at Qc = 0. The star line is 4.1 from 111 reviews. Short comments praise the price and call it a good replacement for a failed unit. Both tiles in one captured test failed within minutes even though the reviewer stayed at or below 7 V. There is no heatsink and no paste in the box. The about £5.99 price is the lowest pair here, and the early-failure note is why it is not the best value. Keep a second plan if the cool box has to work this weekend.
Pros
Cons
Best for: You want the cheapest two-pack and you can afford to set aside a pair that dies in the first minutes.
Less suitable: A cool box you rely on this weekend, or any run you start before a heatsink is clamped on.

Short comments praise the price. Both tiles in one captured test failed within minutes even though the reviewer stayed at or below 7 V. The star line is 4.1 from 111 reviews.
The Lsgoodcare kit is an assembled TEC1-12706 cooler at about £18.78 with a fan, a radiator and a cold plate on 12 V DC, listed at a maximum power of 72 W. Across 93 ratings the line is 4.0. Captured comments say the cooler itself worked well, and that one buyer used it on a dog bed, while a separate note complains about the courier. A bullet says there is no noise, and the noise field is 65 dB, so the specification field is the one to plan around if you care about sound. Seventy-two watts is the listing maximum. The heat lifted out of an insulated box is a different figure once the hot side warms. Forced convection is in the parcel, which is more hardware than a bare plate, and a small radiator can still be the limit once the tile draws several amps. Paste is not confirmed in the comparison fields.
Pros
Cons
Best for: You want a ready 12 V assembly for a small bench or pet-bed experiment and you can live with a 65 dB noise line.
Less suitable: A silent bedroom cooler, or a cabinet you expected to reach fridge temperatures from the 72 W line.
Specifications
Common questions
What thermoelectric part is in this listing?
The listing identifies an assembled TEC1-12706 kit on 12 V DC, with a listed maximum of 72 W.
Does the box include a heatsink or fan?
Yes. The kit lists a fan, a radiator and a cold plate, with forced convection. Paste is not confirmed.
What do the captured reviews repeat?
Comments say the cooler worked, and one buyer used it on a dog bed. A separate note complains about the courier. The star line is 4.0 from 93 reviews.
This Lsgoodcare kit is about £20.99 and lists a TEC1-12706 with a water block, a heatsink and a fan, at a maximum power of 120 W on 12 V. The star line is 3.7 from 40 reviews, below the fan-kit sister listing. One reviewer said the water block belongs on the hot side and then saw rapid cooling. Another saw a reasonable drop once water was flowing and a temperature controller was in circuit. For a fish-tank job the fans and the stock sink came off, and with two water blocks the notes report about 6–7°C between the tank and the waste side. One hundred and twenty watts is the listing maximum. You still send the waste heat into another water volume or a radiator. The included-components line names the tile, a fan, a water block and a cold conduction block.
Pros
Cons
Best for: You already plan to run water across the hot side and you want the block in the kit.
Less suitable: A dry bench that will use only the bundled fan, or a fridge you hoped the 120 W line would create.

The Youmile pair is two SP1848-27145 thermoelectric generators at about £8.99, 40 × 40 mm, with 150°C in the title and no Qcmax. The star line is 3.6 from 35 reviews. The same listing also describes the part as a 12 V cooler, which mixes a generator with a powered tile. A silicone heatsink is named in the title, and paste is absent. One captured set repaired a stove fan and was called good value, and a short UK note said it worked. One of four tiles would not chill and stayed about 2°C below the warm face, which is a weak split if you bought it as a cooler. The SP1848 sheet quotes about 0.97 V open circuit at a 20°C difference and about 4.8 V at 100°C, so the useful output is a small generator voltage. Buy it when the fan needs a temperature difference, and read the cooler wording as a clash on the same page.
Pros
Cons
Best for: You are replacing a generator in a heat-powered fan and you accept a title that also says cooler.
Less suitable: A 12 V cool box that needs a TEC1-12706, or a fan whose maker will only honour its own module.

This ALAMSCN bundle is about £10.98 for two TEC1-12706 modules, two 40 × 40 × 10 mm 12 V fans and two 40 × 40 × 11 mm sinks, with cooling power listed at 60 W and Imax at 6 A. The star line is 3.1 from five reviews, the weakest rated row that still has a star line. One buyer used the sinks and fans, without the tiles, on a retro computer and found the fans relatively quiet. Another called it a reasonable parts bundle if the tiles stay off the title wattage, and the heatsink and fan were called inadequate for the Peltier. Thermal paste is mentioned in the install bullet. The item-weight field is 20 g, which cannot describe the whole kit. A 40 mm fan on a 40 mm sink leaves a 6 A tile without a serious hot side. If those parts stay on the tile, keep the current far below the 6 A title.
Pros
Cons
Best for: You want the small fans and plates as computer parts and you will keep the tiles off the title current.
Less suitable: A cool box, or any project that needs the full 6 A on the bundled 40 mm sink.

The Hapivida listing is a two-stage TEC2-19006 in the title, 40 × 40 mm, at about £31.89, the highest price in this set. The captured amazon.co.uk page has no star line and no review text, so the stored score is 0. The listing quotes a delta-T max of 80°C or more at Qc = 0, a Qcmax of 72 W, an Imax of 6 A and an assembly pressure of 85 N/cm². Everredtronics lists Qcmax at 36 W for TEC2-19006 at a 30°C hot side, so the 72 W line conflicts with that table. The number-of-items field is 1 against a two-piece title, and the box is the module only, with no paste and no sink. Two stages can show a larger temperature difference when the heat load is zero. There is no UK review here to say the ceramic arrived intact or that a box got colder.
Pros
Cons
Best for: You already know you need a two-stage 40 mm tile and you accept a listing with no reviews.
Less suitable: A first cool-box spare, where a reviewed single-stage TEC1-12706 is the usual part and this row has no ratings.

Sentiment and listing conflicts
15%Cracked ceramic, early failure, a 40 mm sink that cannot take the titled current, and watt, voltage or item-count lines that disagree on the same page.
Start with the job, then the module family and the supply you already have, then the hot-side parts in the box. Price comes after those three. The notes below follow that order for these 12 amazon.co.uk listings. None of the scores is a lab test of cooling in a box.
A Peltier element on amazon.co.uk is a thermoelectric module, or a small kit built around one. Apply direct current and a cooler pumps heat from one ceramic face to the other. A generator makes a small voltage from a temperature difference. People fit a spare in a 12 V cool box, replace a module in a heat-powered stove fan, or build a small insulated cooler.
Qcmax is the heat pumped near zero temperature difference. Delta-T max is a different point on the curve. Hebei’s TEC1-12706 sheet is about 50 W Qmax and 66°C delta-T max at a 25°C hot side. Those points do not occur together. A −30°C to 70°C line is an operating range, not the air in the box.
The sink has to take pumped heat plus electrical input. A seller note for a 40×40×11 mm sink puts that size at a few watts. A 40 mm fan on the same plate does not fix a 6 A tile. Power without a sink can destroy the ceramic and burn the surface.
SP1848-27145 is a generator. A title that also says 12 V cooler is a clash. Caframo does not sell an Ecofan module spare. Check the maker’s own generator before a generic 40 mm plate, and do not clamp a cracked tile.
Decide cooler or generator before you compare prices. TEC1-12706 is the 40 mm, 6 A, 12 V repair tile, in two-packs from about £5.99 to £8.99 and a five-pack at about £15.58. TEC1-12705 is the 5 A cousin at about £9.29, with 45 W in the title and 77 W in a bullet. TEC1-04902 is the 20 mm, 5 V five-pack at about £9.98. TEC2-19006 is the two-stage pair at about £31.89, with no star line. SP1848-27145 at about £8.99 is the generator. A USB port will not run the 12 V, 6 A class.
Bare tiles need paste and a sink you already own. The diymore paste pair adds 5 g of HY810 and still has no finned sink: its 40×40×3.6 mm line is the module. ALAMSCN’s sink kit adds two 40×40×11 mm plates, and the fan bundle adds 40 mm fans as well. Reviewers called those fans and sinks inadequate at the titled current, and a 60 litre aquarium note used larger sinks. The Lsgoodcare fan kit, about £18.78, is an assembled radiator and quotes 65 dB against a no-noise bullet.
Three typical situations, each with a recommendation from this comparison.
The cool box already has a sink and you need the same footprint. The diymore TEC1-12706 five-pack is about £15.58, five 40 mm tiles, with 4.4 from 450 reviews. You still add paste. If the failed tile is a TEC1-12705, match that 5 A class instead.
Check the maker’s generator spare before a generic 40 mm plate. The Youmile SP1848 pair is about £8.99. The title calls it a generator and a cooler. Caframo does not sell an Ecofan module. A TEC1-12706 is a powered cooler, not a heat-powered generator.
You want a bare 12 V TEC1-12706, paste, a real sink and a current-limited supply. The diymore paste pair is about £8.99, two tiles and 5 g of paste, with 4.3 from 190 reviews. The heatsink line on that listing is the module size, so the sink is still yours to add.
In this set of 12 amazon.co.uk listings, the top pick is the diymore TEC1-12706 five-pack at about £15.58, with 4.4 from 450 reviews and a score of 88. It is five bare 40 mm tiles and a manual only. One UK note measured about 3.5 A at 12 V. The best value is the diymore TEC1-12706 two-pack at about £7.99, with 4.4 from 249 reviews and the same score of 88. The £5.99 DollaTek pair is not the value pick: both tiles failed within minutes in one test kept at or below 7 V. Neither score is a temperature drop measured in a box.
Diymore TEC1-12706 two-pack
About £7.99 for two TEC1-12706 tiles, 4.4 from 249 reviews, score 88. The cheaper DollaTek pair failed within minutes in one test at or below 7 V.
