- Hello, my friends!
I received a lot of questions about Peltier modules, especially about the TEC1-12706 type, which is actually the least efficient.
But which is the best one? In this episode I will test a few Peltier modules to find out.
A big THANK YOU to all my patrons, especially to: Max Rice, techge and Anthony Ortenzi.

That was fascinating, many thx for sharing and I’m pleased to see your assistant is still working hard keeping those tricky capacitors off the table 😀👍
Not at all😊
What you're seeing is the effect of joule heating. Basically you were able to manage the hot side of smaller peltiers better because heatsinks were larger in proportion.
06 is not rubbish. It has to be planned & executed properly.
Thank you - it would have been nice to see how warm the large heat sync was getting. Liquid cooling would have significantly improved this test.
@@RCToys09 I guess there's a reason why the manufacturer make different types with different price or costing. I bet it not only related with size but also with quality. Using liquid cooling required more electricity as input. So if using same input give different output then we can conclude which is more efficient.
thats it, there was just so much not even considered here, mostly heatsinks...
cold side temp means nothing without hot side too.
lol, heat blocks dont appreciate frozen water. go all bulgy :)
i had to see what it would do with no pump.
do you know what the best peltier model is
Nice video great information without exploding music and wild graphics Thanks !
Really good information for feature projects. Thanks for sharing! :D
I appreciate your hard work. A very informative and helpful video!
thank you for the comparison. i was planning to use one for a power source project. 👍

Same
True
Great video! Just what I was looking for!
Incredibly helpful video, i've bought some 12703 modules for a project I want to work on.
Thank you soo much , your work made my project very easy❤🎉❤
Thank you for this video. It helped me decide what module to use.. ❤❤❤
This is a very good share, thanks man.
Thanks for the great video with detailed comparisons. I am making a small (5l) 12v cooler/chiller for my motorcycle trips as I could not find anything remotely suitable. As I am looking to have a compact design within the wall of the cooler, your video has reminded me that I need to allow for condensation dripping off cooled element.
Please do another video like this one, but in the next video, apply heat & determine which module produces the most electrical power when you use the optimal heating for each module design. From what I see online, the TEC1-12706 can produce 57W at 50C, which is 1.425W/mm2. That means ~702 of the TEGs could produce 1 kW of power with an input heat of 50C
Thank you for the test!!! I am trying to make a chilled mirror dewpoint sensor!
Good to know!! Thank you it helpful!!😊🙏🥰🥰
This man is creating a whole snow mountain but it is very useful thank you bro❤❤❤❤❤🎉🎉🎉🎉🎉
Thanks bro, this was very useful
Finally a comparison review worth watching, hope you can come up with same videos focusing on possible effecient products/model against each other. Keep it Up! Thank you.
Uma ótima comparação, parabéns pelo conteúdo
Thankyou, very informative ❤
Thanks bro for this important video😘😘
Cool. Literally. (and... I changed my mind about ordering the 06).
Thank you, I wouldn't even consider different types without seeing this video
Amazing! I've thought of upgrading a small mini fridge i have, wanna try fan first then maybe a new module. Thanks!
Really good information thanks brother I like it
I think you ar romanian so Salut! Chiar imi doream în ultimul timp sa realizez un proiect cu aceste module, iar videoclipul tău ma ajutat enorm!Mulțumesc!!
Great stuff!
Oh my god, you are really a good man, please carry on, thanks
Your speaker video is still the best on youtube that I could find.
If you would build a ribbon type (or rubanoide) speaker that would be crazy.
How does these modules compare under bigger loads
Like cooling of 500ml water
Nice researh done!
The TEC1-12706 needs a bigger cooler then TEC1-12703, with the correct cooling the 12706 can reach quickly to -18 - 20 Celsius.
What if u add the bigger cooler to the 03 module?
Thanks for taking the time to explain to us the difference. I am pretty sure that the 4-5-6 didn't perform as well as the 3, only because it didn't reach the appropriate amp. to perform 100%. On the other hand, to get -20C with only 38 Watts of energy is fantastic! Exactly what I am looking for. Thanks
How do you get it to reach the appropriate amperage? My Peltier chips always run at around 3 amps - far lower than their rated amperage. I have been wondering about this.
yes. each module operates in a different sweet spot. more extensive testing needed
@@FHDesert It does reach the maximum amp. but his cooler is not good enough to remove 72W plus the amount of heat energy from the little cold Radiator. So the hot side gets hotter as it should. That follows that the cold side doesnt get as cold as when he used the 12703
Awesome comparison, now I know why 12703 cost more than double...
Currently working on making a pretty sick Portable AC using these chips. Alot of design is going into it these chips are amazing especially when used correctly.
I'm doing something similar! But with a pillow. How many are you using, you'd need a lot to make any sort of difference even in a tiny personal fan. And you'd have to vent the heat elsewhere or else the net difference is just heating up the room! I'd be interested in seeing your creation.
I have been searching for this info from a long time finally I landed into correct place very useful info abt peltier module if I had watched this video early I would have not buy 12706 module.
great video love it❤
Thanks a lot glad I watched this
Thanks 👍🏻🙏🏻🙏🏻🙏🏻 very informative and technical video
Nice video!👍
Are you planning a cloud chamber Sorin?
excellent information that was what I was looking for to know what power each peltier plate has. I bought 127015 and it consumes a lot of current and the temperature drops. if your information is correct I go Buy peltier 12703
Thank for sharing
Thank you so much!!!
Thanks for your information🥰
From Bangladesh
I was planning on making a peltier water cooler, I planted on using some 12706 modules I already had, but I think I'll get some 03 ones instead. Thanks for uploading!
tnx for the info ❤❤
crazy and almost magical technology I was unaware of until lately. I would be curious about this same experiment with numbers on the heat side also
Repeat the test and track the temp of the large heat sync. You will find that the large heat sync can't keep up with the heat generated by the larger peltier, and it will be hotter with the 12705 than with the 12703. This explains why the temp was greater at 60 minutes than at 30 minutes - the ambient temp of the heat sync rose. A peltier is designed to create a thermal difference between the hot and cold side of the peltier. The colder the hot side is, the colder the cold side will be. For air cooling, the 12703 is better. With liquid cooling, the 12705 will remove more heat than the 12703.
Great! Could you please make also tests with TEG Modules to make power from heat? Ive noticed that there a great differences by modules and prices.
+1
Yes I would like to understand the differences in energy generation also maximum temperature each on can handle
Test is very good, but only for this size of radiator. If u get bigger radiator with better cooling , u get better results on more power peltier module. so this test is only for this small radiator on hot side.😊
Quite similar as to what I was thinking. Smallest-size peltier (12704) performed "best" compared to the group because of its smallest physical size in proportion to the (heat) radiator. Increasing the cooling capacity (ie: Larger radiator or more fan cooling) in proportion to wattage output needs to be considered to make a fair comparison.
@@Schrimpieman yeap, thats right ;)
@@Schrimpieman you got it.
Lots of love ......from India🍃🐣
what happens after 12 hours
Ooo, esti Roman, m-am abonat instant
It is great for aquarium cooling ! Every new summer temperature are going higher and higher . Thank you
sorine imi place mult e faci si mult succes
Beautiful sharing
Very informative video. Thanks for sharing. Do you mind revealing what thermal paste you used? I am finding in my own testing that this is making a big difference in temperatures I am measuring on the cold side. I changed thermal paste on a peltier/heatsink module that I had purchased and the temperature I was measuring was at least 7 degrees C warmer than it was before the paste change.
Hi. In this video I used a medium quality thermal paste from aliexpress. With better quality/more expensive thermal paste I would probably get better results.
The modules have different electrical specs and they're being driven with a fixed voltage, the ideal way of driving a peltier module is using a constant current (CC), as resistance varies with temperature. Idealy the module should be driven within 60-70% of its maximum current to maximize lifespan. The last digit of the modules indicates their maximum current. The TEC1-12703 has a maximum current of 3A and is being driven a little above its maximum current. So, this module is being overdriven.
My suggestion would be to compare them using CC at the same percentage of the maximum current of the module being tested.
Thanks for the suggestion. I bought some new Peltier modules and I will test them in a future video.
Thanks
Excellent 👍👍👍
I have Peltier module TECH1-12706 DC I need out put heat so plz how Many volt and ampere have to give thx
thank you sir
Sir, I really appreciate your hard work and I request you to make a Tesla Coil in your next video, I will be waiting.....
I think there is new update for our mini fridge video 😁😁. Waiting for it.
Please try some test with SR-4902 or TES1 -07125 23x23mm thermoelectric element , can we use this as mobile cooling system
I built an ice chest air conditioner. At bottom of cooler is ice cold water and a bed of 20lbs of ice Sitting on a wire frame. Just over the ice layer is an internal lid effectively separating the ice chamber from the air intake chamber. 2 radiators ; one is for intake air the other is for the precooled air blower fan. My question requires your expert peltier knowledge. Cam I usea few peltiers to create a mini freezer keep ice colder longer or make circulating water even colder with salt? I'm concerned about cooling the hot side without heating my ice water. Thank you for your channel and all you do to help us
Hi. my next video is a project with Peltier modules, it will clear a lot of things about your project. I will upload it in a few days.
good job
why my 703 not like that only 2degree how could you do that -19degree on 703?
Good work bro🤜
Can you test all 4 as thermoelectric Generator?
The ones he tested are TEC modules. What you want to see are TEG modules. One creates heat/cold and the other electricity - TEC can be used for both purposes, but probably not with the same result.
How to power peltier module can it gust be pluget into a power outlet
Excelente amigo😊
Hi Sorin, Thank you for posting this video. If I were to use a Peltier module in reverse, to apply heat to generate a small amount of electricity, would the 03 module be best choice for being the most efficient, and producing the most electrical energy? Thank you
Hi. I haven't tried it. I think this is a good idea for a future video.
Please try some taste with SR-4902 thermoelectric element , can we use this as mobile cooling system
Hi, I was wondering where you got the ice from even though you didn't use any water? Was it the thermal paste that developed the ice?
Hi, moisture in the air turns to water on the cold surface, then to ice.
@@Sorin_DIY Thank you, this is very helpful.
Nice video ❤❤ more video
Hi. Tell me, what type of Peltier do I use for a "Philips perfect draft" machine? Thanks. David.
Hello. I didn't work on this unit, but I found on internet that it has a 70W peltier element and the similar cheap alternative is the 12708. But in my opinion you should buy the 12703 and 12706 modules as well and test which one works better. they are cheap.
thanks
Great video, but I have Concerns.
Later on, you chose the TEC-12703 because it cools down to the lowest temperature. In the mini-fridge you've build, the Amount of heat the Peltier has to remove is much higher, and the Qc of the 12703 is very low. Dont you think the 12706 does a better job when the amount of heat that has to be removed is quite high?
Thanks! TEC1-12706 may be a little better in a closed box, but it draws more current and it needs a bigger heatsink, so the entire cooler will be bigger, more expensive and will draw more energy.
I will make a more detailed Peltier test video soon, with more powerful peltier modules, bigger heatsink and different voltages.
@@Sorin_DIY I'll enjoy your new video :) I hope you're maybe cooling a liquid or gas with the different peltier Modules, so that we can see how much heat energy is removed through the TEC's. Looking forward to it :)
Hi sir, if we use that peltier module alone without heat sink and fan, module can be damaged?
Yes, it will burn.
THXYOU
Please try some taste with SR-4902 thermoelectric element , can we use this as mobile cooling system 5:07
another reason It might do better after 30 minutes than 60 is the ice forming on the cold sidn acting as an inulator, not allowing for thermal transfer
Great video, is it possible to add a 12702 peltier module in your twst? Thanks.
Thanks! I will make a second video testing Peltier modules, but I will focus on more powerful modules.
Bro im making a mini ac with 4 peltiers of 12v 6amper i have a SMPS of 20A
My question is. Should i use one yellow wire and one black wire from SMPS for all 4 or i should use connection separately for each peltier?
It depends on the thickness of the wires. I suggest you use separate wires for each module, or use a 2.5mm2 wire for all of them.
5:07 Is there an error? The chart shows the 12703 Takes 3.18AMP but in the background the PSU shows 3.27AMP
Hi. There is no error. the cooling fan also draws 0.09A from the power supply, so the total fan+peltier consumption is 3.27A
Oh! I gotta recalculate some stuff then! Thank you! I bought 20x of these Peltier modules you posted@@Sorin_DIY
Is it possible to run it for some minutes without the active cooling? Can I use a powerbank to run the peltier? How can I calculate how long my 2000mAh would last with the 03 peltier?
You cannot use the Peltier module without a heatsink, it will heat up in a few seconds. using a 5V power bank will have a low efficiency, you should make a battery pack and connect it directly to the Peltier module.
@@Sorin_DIY how big would that battery pack be? I am a total beginner somehow... is that batterypack portable... listen: I want somehow a way to cool down my shoes ... I know I know.. but I have a gen defect that gives me blisters in summer if it is too hot...
nice video
Please how do you get the aluminium radiator and fan Please
Interesant. Poate in viitor o metoda de a produce energie electrica din aceste module . Eventual atasate pe spatele unei sobe ?
Which SMPS you r using sir
Nice video and analysis. Could you please suggest best PELTIER module for heating application? Thanks in advance
Hi. I haven't tested Peltier modules in heating applications, maybe in a future video.
Least efficient at cooling would likely be best for heating. Peltiers move heat from one side to the other but in doing so they convert a lot of the input electricity to heat which goes out the hot side. In other words they put a lot more energy out the hot side than they take in the cold side.
I'd like to ask if it's practical to make and use a portable air condition using the 3 amps Peltier module in hot countries like here in the Philippines? and how many modules would it need to make it efficient to cool down a small area or room? I'm just curious.... Thanks for this video....
No, peltier devices are not very efficient for cooling and a power output of 1000w is suitable for a medium size room, so at least 20 of these.
@@321tryagain Far more if you want to operate at a reasonable COP and at that point you'd have a very expensive and weak AC system (assuming you actually take care to pump the heat outside)
hi can i get around 0 centigrade in 40°c weather with 4×4cm heat sink and 12706 peltier? i want to build a phone cooler but the peltier gets too warm
no. you need 1 or maybe 2 peltier modules 12703 with a big heatsink.
@@Sorin_DIY but the main thing is building a phone cooler it can't be that big
then you can power it with a lower voltage. because a 12706 peltier module with a small heatsink will get very hot.
i think you need to supply 12v 6amps for the 12706 module, for its full load to work.
it wont draw 6 amps at 12v, it needs 14v or higher.
Can it be possible to have a bigger size of a radiator so it can produce bigger ice ?
A bigger heatsink on the hot side will be better.
That 03 module is as cold as my freezer, fain
Sir does the TEC1-12703 can be operated using only a 12v battery?
yes. but you need a powerful battery.
@@Sorin_DIY how about 12v 20ah of motorcycle battery?
Sir I'm making a chiller for 30 litter water . Can I use 12703 peltier for this project?
yes, but you need 2 or 3 peltier modules.
