Can we turn our backpack stack of power tool batteries into an inverter that powers corded tools? Are there better options? What if you don't want to pay the crazy prices they ask for matching batteries? Today we try and make corded tools a bit more mobile and have some fun along the way.

Day 2 of asking you to Test the tecpo 300111 Air Impact
@@steinestapler726 We dont have them here in the states it looks like
@@TorqueTestChannel thats sad Maybe we can find one that can send it to you. I am Not able to send it to you because i live in Germany, and i need IT daily.
I wonder how powerful a tool would be if it was designed with modern brushless tech but was still wall powered.
I asked 10 or more times for a tool review without even a reply lol lucky you got anything back at all
Those commenters dont know what they're talking about. I love the jank, sketchiness and creativity of your build videos
Probably just Chinese bots
just stuck up geezers
That's why we're here lol
"Old man yells at cloud"
Agreed
Anyone calling these builds stupid lacks the ability to read between the lines. The engineering alone is enough to learn from, regardless if it's actually useful or not, the point is to find out. I'm not necessarily expecting peak performances but I enjoy seeing what you find to be the minimum required wire or battery size to perform at all. The differences in battery performance from one brand to another is interesting as well. Showing people they can simply notch an adapter rather than have another one made is another little tidbit of info to keep in the back pocket. I did that back in the day with some batteries themselves to fit certain tools and they worked fine. Love the vids man. Thanks. Merry Christmas.
Average human doesnt even know that AC batteries dont exist. They think why bother with tools DC batteries when you can just chug an AC battery and use their corded tools.
I just want to say that I didn't think the idea was stupid! Before I had cordless versions of certain tools I was making my own cordless tools, but before that I actually had connected packs in series so I experiment to run my corded tools, Way back in the Days of nicds so you can imagine I had no long runtime like that we have today. Which brings me to my point that you could just run six 18/20V batteries in series and you would have 120 volts DC which is actually going to be a lot more effective than inverting because the universal motor is more efficient with DC than it is with AC, and as you noted by far and away most power tools are universal motors, not to mention the inverter is the bottleneck in this situation. Enjoyed the video!
does it work with tools that have speed control? will it not blow-up the triac or something?
@@pisig98b If a tool with uni motor has a speed control, all it should do is run flat-out: the triac fires and say on until you release the switch assuming it breaks the live wireIf the trigger only disconnects the triac's gate driver, then the motor won't stop until unplugged. 250V AC switches usually aren't rated for more than about 32V DC, breaking non-negligible DC current will likely wreck them pretty quick.
I think your onto something there!
@@teardowndan5364Switch problems were my first thought.
I tested a 120V switch in series with a heater and 4 M18 batteries (20 volts each at maximum charge. (ruclips.net/video/wZ5_mGM_VAY/видео.htmlsi=205r5W-hWlO7A9E0) The switch arced and melted violently at only 10A 80V.
@pisig98b It should still work,it will just be using half of the triac, and might only run full speed, But dont know for sure everything I ran was simple on -off switches. I wouldnt think it would damage it but might want to try one you wont want to cry about losing first.
For many tools with older motors, you don't even need an inverter. Universal motorbs run on both AC and DC, and even a little better on DC.
Please test this
This is a complete lie ac does not need brushes to run and dc does so an ac power tool would not have brushes in it unless they wanted to add allot of extra wear parts and cost to the tool for no reason which makes no sense
@@PeterTrimbolia lot of power tools use a universal motor.
@@cameronwebster6866 right they are ac motors that's how they're brushless the dc goes into it then through electronics the dc is cut up and stepped into a choppy ac sign wave depending on where the sensor tells the electronics where the motor position is brushless tools are a little more complicated but you can't just put ac into it where the battery is so it's technically only for dc unless you made another port on it that could take a plug that goes straight to the motor in theory that's possible but no ac circular saw should be able to take dc unless it was specifically designed for it because it would mean extra wear parts less efficiency and more cost to build.
@@PeterTrimboli I don't think you're talking about the same motors. Universal motors are a specific kind of BRUSHED motor that can run on both AC and DC. Plus, since the OP mentioned "Older" devices, there's not likely to be much in the way of control electronics in the first place. Even if there were, unless the current passes through a transformer before getting rectified for some reason, I don't even know that the control electronics would be particularly bothered. Whatever is powering the electronics would expect to see 170V rectified mains voltage regardless, right?
As others have suggested: Definately try running the saw on DC. No AC conversion needed, but how much torque will it make at what voltage?
This.
+If you like your saw, ziptie the switch closed and put another switch in series. High breaking capacity circuit breakers work reasonably well. That avoids turning the original AC switch into a puddle of copper (been there, done that)
I find it amazing how he does all that measuring and electronics DIY stuff but doesnt even have basics theory knowledge. The last battery bag video he didnt even think about using a simple diode before hoking the batteries together(the preffered method would be mosfets btw). He probably doesnt know how a brushed(universal motor) works. Just 6 batteries would be more than enough to run a power tool.
@@JonaJonaI see what youre saying but is 110DC at 10 to 16amps enough to weld together a switch or just melt it? Most switches are rated for 240(ac) at 16amps anyways. Thats like 340v peak
@@zaxmaxlax When switching DC loads, switches are normally rated for between 1/2 to 1/4 of their AC switching capacity.
@@zaxmaxlax on DC there is never a zero voltage crossing like on AC so the arc when the switch turns off doesn't extinguish easily. most switches that are say 20 amp AC will only be maybe 5 amp DC . same problem with larger DC breakers. i remember in motor lab back in college in 1980 we had a setup with 50 amp DC air breakers . when they switch the arc was like 8 inches long. they flip open in a rotation and the arc follows till the thing has opened over 180 degrees.
"here's your friendly toaster oven"... *plops down a $300 Breville* 🤣🤣
I do have the step up from that one btw; its preset settings makes great work of pizza and cookies!!!
Corded tools have universal motors. They run on AC and DC as well. Here comes the sketchy part, put 6 20v batts in series for 120v. Or 7 for some extra juice.
This is exactly what I was hoping to see!
I suspect that since most batteries have circuits in the pack, they would not like being put in series and having 120V+ run across them.
Actually, since universal motors self commutate. Should only need 60v DC to equal the power of 120v AC. Likely will see more power on DC as theres more current on tap.
@@DangaRanga 120V AC is an RMS value, not peak to peak so the commutation should be irrelevant when comparing to DC
It would be more efficient using two 60 volt batteries in series then use an inverter. 120v DC is more powerful than 120 AC.
Not only are the stats and specs right on par, your sense of humour and the quality of your funniness is right there also!
"Let's see what you're gonna share the blame in today" perfectly condemns the haters.
Bring the beans.
I watch these builds while I build silly things. Makes me feel less alone
There are many secure locations Ive worked in that had no allowed outlets. This would actually usefull there or when working in the center of an unfinish massive Wearhouse space.
I can't imagine how nice it would be if all brands had the same battery platform so you could use it all together
Air hoses and cords are the great equalizer
In a way they do actually, they all use 18v batteries(some market them as 20v or 19v, but they are all 5s lipo's so 18v), so all you really need is to download an adapter if you have 3d printer at home or know some one with a 3d printer.
Not that simple...
And they are not lipos, they're lithiums.
Lipos are significantly more volatile.
@@Poo_GardenDoesn't lipo mean lithium polymer? So wouldn't that be the same just different format and in a smaller package in the case of Lipo packs.
@@Poo_Garden Yes it is actually THAT simple, 5 rows of INR 18650 cells in a series it's all the same, trust me. You just have to use same brand charger though because of BMS compatibility. Also some battery packs have output leads go directly from cells and rely on BMS to send a signal to tool to cut power when battery is low, so if you use that type of battery with an adapter there is a risk of over-draining them, but than again you will notice the tool being too sluggish to do any work long before you over drain the cells to the point of damage or not accepting charge again.
There will always be cranky people out there. None of this is stupid. Thank you for sharing and giving us a good content. Love it.
There’s a lot of really sad and lonely people out there. All they want to do is poke the bear and see a reaction.
Ignore "keyboard warriors", do whatever you do, i have two shops full of tools (even in my bedroom i have tools) and watch this gladly and enjoyably !
Thank you.
More .... everything! 😃
Every time someone shows up with a corded tool on the job I will now show them this. 👍
I am here to see all the crazy being hacked, zipped tied, glued together stuff. It's just awesome 👌 and never enough.
These kind of videos are so fun to watch. I'm really enjoying the backyard engineering stuff.
I stumbled across this channel right about when it was just starting out and I've been watching it since. It encouraged me to get a makita impact wrench even though as a plumber I don't really use it that often.
Keep up the good work guys. You make awesome videos.
Greetings from The Netherlands!
Please disregard the deplorable statements those guys made. Your channel is one of the best ones out there, and that episode was entertaining and educational because you explore the cracks and crevasses of science that not many people can, because not everyone has a mind to think. What you did in that episode was what many great minds before you have done right before a great invention was born. Science is observable, testable and demonstrable and thats what you did on this channel...SCIENCE. The difference between working at a worksite where a boss tells you what to cut and bolt down is that 'your a boss and think like a boss' and all they can do is criticize others then go home with no idea on how to be a boss ....so you keep up the excellent work and let the haters hate while you make your bank with over a quarter million subscribers . This message was brought to you by someone who isn't half as knowledgeable as you, but really appreciates the work you do. May The Lord continue to bless you and your crew.
I will take the blame! I love it 😂. I actually have an older video using 2x 56V EGO packs to run some 120AC tools that still use universal motor to this day. It will work, but the switches are the failure point as can be expected unless AC/DC rated. Keep up the fun videos. Merry Christmas and Happy Holidays!
Please don't listen to the negative comments. If they don't like the show dont watch! Please keep up the madness i love the ingenuity of the lateral thinking.
I love this channel. Just thank you!! Your videos help make the work bearable.
I'm here for the banter. Love the content!
Don't the motors in circular saws and miter saws run on AC or DC? I was hoping you were going to stick six of these 20 volt batteries in series and run them direct on DC. That way you wouldn't have all the losses in the huge heavy bulk of the inverter system.
Edit: to be clear, I know they're not advertised as being able to run on DC but the type of motor that it is I think can
Exactly what I was thinking! AC Circular saws and angle grinders usually use universal motors, which do run both on AC and DC. They should even be more powerful on DC, if the voltage is right. You probably don't even need the full 120 V, so that would definately make for an interesting video.
Can confirm. Brushed motor corded tools love DC power.
Correct. Some do and some dont though. Induction motors don't but it would work for the couple here.
@@TorqueTestChannel sounds like another follow-up with a rewired Frankenstein backpack from the first video!
@@MrEnginerd I've run a circular saw with batteries in series but you loose speed control on tools with variable speeds.
I loved the back pack and all things you guys do! Keep up the good work! Happy Holidays and Merry Christmas!! Looking forward to the year to come!
This was awesome. These kind of experimental endeavors are when you find something surprising
Y’all’s creativity and then ability to execute your ideas is immaculate. Hercules just came out with a 2nd Gen. of their compact impact wrench. Still crazy high numbers but I’d love to see if it’s a step up from the previous generation. Test it please!
I live for the jank. Also the awesome data you guys provide.
Not stupid.., this is why i watch your videos as you do the stuff that i think about. 😂
I was thinking the other video was gonna go the other way but then I was surprised and delighted to see where it went so I didn't care I'm glad we have a version two is well.
Don’t listen to the haters!!! Y’all do what in the HELL makes yall happy!!!! I’m here for it all and love everything y’all do!!!! Keep up the great work!!! Thank you!!!!
Keep the crazy ideas rolling it’s what makes me live life
You're definitely not stupid! You're learning for all of us and for that, I am grateful!
Merry Christmas!
the haters are the worst. I love this content. keep up the GREAT WORK yall.
The bad thing about anonymity is it manufactures courage in cowards who make fun of others via a keyboard and say things over a message board that they would never say to a persons face for fear of having their face rearranged. Personally I believe in supporting creativity and that's the reason I love this channel. Keep up the awesome work and ignore the haters.
Honestly the most valuable information for me in this video is all the information about the battery tech.
Would love a video comparing all the different battery brands, and which ones have the same cells, which "last" longer over time, better discharge, which have under voltage protection etc.
Would also be a great addition to your spreadsheet
Happy to be culpable in these shenanigans. Keep up the great work!
Honestly guys i loved the backpack idea. Dont let the haters get you down.
Ketchup & Mustard! LoL. Love it!!
Excellent work! Thank you building the dreams of water cooler talk! /cheers
Damn people be harsh over a video I’m sure no one asked for. It’s all for scientific experiment and data anyways so whether a small step in the right direction or wrong, this is what this channel is about.
Yeah calling it stupid was a tad harsh, it was educational and entertaining. The inverter makes sense for the reason you pointed out as it's portable. Still one of my favorite channels. I don't buy any tools before checking here first. AVE up in Canada is also awesome
Always fun, keep it up!
Don't mind those nay sayers. You guys are top notch. I eagerly await for new videos every week. Good fun. Good reviews. Good science. Keep up the good work.
I love your videos and the out of the box ideas! I would love to see you test battery powered tools using lipo batteries. Atleast in rc lipos reign king for high load high power applications. I’ve noticed most battery packs are li ion which doesn’t hold a candle to lipo’s under load
Well done sir !
I finally received my Denali screwdriver. Very nice tool! Amazon asked me two times if I still wanted it, and it's finally here, lol!
Juat bought the dewalt to milwaukee adapter thanks to you. Done with $250 batteries.
Its always easy to be a troll or mean online, but i love what you guys do and the scientific way you go about it. Ive bought a lot of my tools as a result of your vids; at best its innovative, hilarious, and informative (hard combo to do), and at worst its interesting and entertaining. Thats a high bar. Great job guys and keep up the good work!
This M18 inverter is a beast
the only one able to handle my 1994 Maytag washer and dryer
Not a Ecoflow, Bluetti can even get the motor to spin
i Love it
I am an engineer, and I approve Torque Test Channel 🙂
I can't see how anyone that watches the cool things you do on this channel can think any of it is stupid. keep doing what your doing its great!!!
0:51 "...and yes, we got plenty of comments calling this backpack, and us, stupid. Uh, yeah you're 💯% right, the channel that brought you gas-powered impact wrenches that nobody asked for made a death box of a backpack to juice up tools an extra 10%. Nobody over here's tryna sell ya something, or even pretend this is a good idea--the stupidity of it all makes it awesome, and you watching this right now makes it all happen, so... you're all culpable. 🤣" LMAO BEST RESPONSE TO HATERS EVER
I like your "current" set-up. I can't wait to see watt you can make next.
Great job!
Very interesting!!
I enjoyed the first episode of the backpack. It Was an entertaining video
I built a backpack power center about 20 years ago, similar to your first attempt but with that era tech. In a backpack, I put in a lead-acid battery intended for a large UPS. Probably 1/3 the size of a car battery, maybe 20 lbs. Then paired that with a 12v inverter, and added a slow charger conditioner. The key, as I think you exposed, was the inverter. For reasons, I had high-end inverters in my parts bin. No Amazon cheapo crap, these. With this setup, it could run a 12-Amp AC tool continuously, and could spike to double that for startups +-. The backpack would run an AC edger, trimmer, blower and hedge trimmer (and for projects, circular saw, shop vac, and every other tool I had except one, which rejected the modified sine wave, I think). I also converted an AC lawn mower using a similar setup, but on-board. This did all the yard work for an 1/8 acre lawn on one charge. The Achilles heel was the LA battery. After about 6 months of discharge cycles, they would be flat. Fortunately, LA batteries were cheap at the time (and recyclable). Deep cycle helped, at a bit more money, but the most I got was about 8 months of weekly yard work. The system as a whole did all my yard work for about 5 years. I was about to convert to early lithium battery (at huge expense), then Ryobi released their "40v" mower, and well, for better or worse, that's where my money went. This was a fun video, bringing back some hack-tastic memories.
Very cool stuff! Sadly people really dont seem to understand how scientific experimentation works (the recent pandemic put that in stark relief) but this Ph.D. appreciates your spirit of inquiry!
Great video! A good stress test for corded stuff like this is a table saw. My EcoFlow Delta 2 ($649 on sale, 1800W, 1024Whr) will run nearly everything in the garage: Skilsaw, miter saw, MIG welder, compressor (not all at once of course), but it won't run the table saw.
These guys and Project Farm always put companies on high alert when they order a product. People like to know what they’re paying for and people like this make it happen! Please don’t let this go
The stupidity and sketchy stuff is what gets my down stairs mixup fired up....those people can go find less. Keep doing what you're doing guys.
So ridiculous that I love it! Keep it up!
Nice Beefy test. Merry Christmas you guys.
Unrelated to this video, but it would be nice to have a COO slot on your tool ranking chart.
I don't know if I'm the only one who would be interested in it, but I though I could at least mention it.
Thanks for the great videos and tests!
Thank you for having a nice attitude about so many people calling you stupid. The Internet made people just awful to one another :(. I'm glad that you pointed out that you weren't trying to sell anything. Keep on doing what you do and let the insults keep padding your videos in the algorithm, I guess ;).
The way you listened to your viewers was surprising 😮
I like the stupid. I was expecting four Flexvolt batteries set up for 60V in a 2x2 config, for 120V and up to 10Ah on the big boy batteries. Should work fine with universal motors and there would be lots of amps on tap. Would be interesting to see that.
Yes yes yes yes!!!! Been asking for this
People are weird af and rude. Zero capacity to enjoy life and open their damn minds.
I freaking love this channel and do not use power tools for work.
Interesting, useful information presented with a good sense of humor, edited well..always good videos.
Good job crew and Merry Christmas to each and every one of you!🎄
Lots of us appreciate your efforts
Something on your first set up was bad eather inverter or the converter i have 2 1,000w inverters that will run a 15amp circle saw not at full power but have used them several times. I would have them under the hood conected to the battery with a old set of jumper cables. Love your videos thank you!!!!!
the shop vac ratings are not about startup. they are about a theoretical peak power output which factors in the inertial spinning mass of the rotor. this number can basically be arbitrarily high depending on the test setup and has no real value whatsoever.
Correct!
I always wonder how many horses it would take to create a vacuum....
Depends how winded they are
Ryobi has finally come up with some large capacity 21700 batteries. Works live to see those tested
Please rate battery inverter systems. I was unfamiliar with this 3600 watt Milwaukee. I would love to it next to Ryobi,DeWalt,and Ego. The information you derive is far more useful to me than anything else I have seen. Thank you for your work.
Experimentation is how some of the biggest discoveries are made
That replaced plug on the Makita circ saw is a nice touch, just how much e-tape can a repair take. Thanks for all the great videos and looking forward to a great 2024 from the TTC.
I have the exact toaster oven ❤❤❤❤ works great
An EcoFlow Delta 2 was recently on sale on EcoFlows eBay store refurbished for less than $500(1kWh, 1800W continuous output), and they had a Delta 2 Max for just over $1000, (2kWh, 2.4kW continuous and 4.8KW peak). I have a D2M and ran my shop air compressor(20gal 13.5A) no problem. Also ran 3 window AC units off it this past summer. Make an adapter and feed your batteries into the MPPT inputs😁
Keep the content going, should add a fuse here and there, she may get a bit spicy if something shorts.
We can only seem to get MX inverter in Australia, but they are soooooo expensive
another benefit of the battery inverter setups is the noise. much quieter than the gas generator and no fumes to deal with. something i consider when getting power away from the wall.
This is not stupid, this is a beautiful creation.
I did build a box of juat batteries 30s2p i believe with a 120v outlet and it works fine for brushed motor tools
I personally love the experimental videos. Gas powered impacts, making cordless tools into corded tools, corded tools into somewhat less corded tools, sure it’s unfeasible for most of us, but it’s just entertaining to see what other people can cobble together to make some pretty impressive things.
This is gonna be good.
I've thought about making a hard or soft start capacitor plug and play cord old school like in a junction box spliced in between a short extension cord. Might help with the smaller inverters.
Love it! I did the same thing.
But you don't need an big heavy inefficient inverter. Just hook up your batteries in series for ~110Vdc then alternate polarity with a ~10% dead band for arc quenching.
Mine is a briefcase, but the backpack idea is better.
The haters are still watching and contributing to the channel’s success. Haha I love the experiments and this channel may be influencing some manufactures in the background.
I’ve always thought about doing this with one of those lawn carts, and a bunch of car batteries.
Great test and quips as well. I bought a DeWalt, er, mustard invert rated at 1800 watts. Two outlets and it hasn't run anything i have plugged into. I bought it primarily for the air compressor and jump pack but I doubt this thing could run a coffee maker
I feel like every maker channel needs to open their videos with "Let's see what you're going to share the blame in today" from now on! Hahaha - great retort!
Really interesting real world data on the Chinese inverters, would be interesting to expand that testing to perhaps many things to do with home solar, I've been poking around those prices lately, used panel efficieny? new stuff? chinese vs USA, inverters and battery banks? Huge fan of your content
Ignore the negative comments! You guys rock and all the rest of us love your tests, builds, and everything else you do!!
Curiosity isnt stupid. I love the backpack. This is basically the new Mythbusters but for tools. I love it
Bring on the sketchiness plugging in directly to the tool to battery I wanted to see but still great to know.
Dr. Frankenstein would be proud!
Good stuff! 😉
I would like to see you guys test the Milwaukee MX line stuff
someone else has probably pointed this out already, but brushed corded tools like most of the stuff in this video (grinders, saws, drills) are using universal motors. They can actually run just fine on AC or DC... but it needs to be around 120v... so 6 18v batteries put in series should be able to run all of those without the inverter.
I'd love to see that tested next. :D
I wish we could see a video of the wobble sockets and what kind of power loss happens with them. Maybe a couple different brands as well? Done at different angles like straight on, 1/2 bent and full bent? And different styles of them like the u joint wobbles with the pin style and then the impact versions with the ball style. Would be interesting to see how those stack up in power loss
11:58 you can say, shorting the motor makes a huge difference, which is what happens when you lock it up. creating a lot of amperes
I like your videos. Thank you
