- Adding a power cord to a battery powered device. Sounds like we're moving backwards, but sometimes nothing beats the simplicity of plugging stuff in.
I did this for my Brother Label Maker PT but works for anything that uses lots of batteries.
3volts(2-batteries)- amzn.to/2k9HcQX
4.5volts(3-batteries)- amzn.to/2jXjdSG
6volts(4 batteries) amzn.to/2jXiiSe
9volt (9v battery or 6 1.5v cells: amzn.to/2jDzRWe
Universal Changeable voltage- amzn.to/2jaoOb4
DC power adapters 5pcs - amzn.to/2kzlSoC
Honestly didn't think I'd find a youtube video for EXACTLY what I was looking for and with no added nonsense. I appreciate you sir.
You took the words out of my mouth.
exactly what I was thinking!
@@crazycookie76 Yes, he was very concise. Not trying to be sexist, but I am a chic. I have 3 - $12 really cool little light up running water fountains I want to change over from battery. Need a little Zen around my work area. Because he was so concise, Now I have to look up how to solder, (after I just googled how to spell it...) AND I'm not quite clear on finding the positive and negative wires on the device. More RUclips in my future.
@@ginadagostino8346 that's fair. I guess it's just that some people don't need the added information, while others do. I'm thinking how usually I find the opposite of conciseness in these kinds of videos, so I appreciate that the concise ones exist too!
@@crazycookie76 I get you. Even though what I said was true, I was trying to be funny. Guess I didnt try hard enough. HA!
Oh my goodness I can't tell you how frustrated I get with having to replace batteries after a day or two, this has made my life so much easier and your directions are simple, no nonsense, no filler, just straight to the point, telling me what I need to know so that I can get on with the job I need to do... Thank you my guy
It's pretty important to verify the voltage of the adapter and especially if it's a used adapter you're using . I noticed that one said 6 volts and the other one was a 9 volt output adapter . Another point is to verify the amperage requirements for whatever device is being used and to make sure that they're both the same . Using a multimeter is pretty important for doing this type of thing .
You're using batteries and the device is made to use the amps that batteries put out.
www.techlib.com/reference/batteries.html
been doing that since I was a kid on all kinds of things. This is very helpful for people to know its that simple to not have to use batteries. I used to make battery shapes out of small blocks of wood with screws for the terminals to use a wall wart with something you wouldn't want to solder to like the old yellow Sony sports walkman.
I still have my small yellow Sony Sports Walkman somewhere in my parts bin.
sixtyfiveford I still have mine somewhere too
Thanks for the amazing tip. I'm impressed by how professional it turned out like it was made that way from the factory. Impressive as always.
Thanks Man.
@@sixtyfiveford Yeah tell me about it. It really looked like it came from the store that way. Unbelievable. Super impressive. Can I just pay you to convert my 3 little $12 lighted water fountains? The batteries last less than a day. Supposed to be providing a zen environment for me while I feel like throwing them across the room. I don't know how to solder either. Being that it's a water device, I think I might electrocute myself. Found this video on my first try though. One stroke of luck in my favor. Like and subscribe.
Good idea, but some wall warts are not a regulated voltage and can produce a much higher output than expected with light loading, it can damage devices.
So a 3 pin regulator will need to be placed in line with the power, a simple 7805 (5v) one will do for 4.5v devices, for special voltages the LM317 variable regulator is a simple device to use.
Dont use mains supplys on am radios, lots of buzzing lol.
Most I've seen will produce a higher voltage with no load, but taper off quickly to the spec voltage or slightly lower under full specified load(500ma). This 6v one probably sits at 7v unloaded and tapers down to 6.5 under the light load. My thought process is these battery powered devices are meant to have a wide voltage range as cells can be 1.6(new) to 1v or less. So this device with 4 cells will easily handle 6.4v to 4v. I could probably even drive it with 8-9volts without harm.
Just remember that not all devices can cope with a higher voltage, ive spent the last 30 years repairing electronics and ive seen far too many dead items because of wrong power adaptors, or wrong voltages fed into devices, excessive ripple is also a killer.
im just saying that some adapters are much cruder than the label states.
this is why im not doing this hack...
This comment is correct. A vast majority of these wall warts are not regulated and the initial high voltage can blow right through some chips.
That, and no effort was made to determine the proper amperage capacity of the wall wart.
That's a handy tutorial right there. The way your mind thinks is amazing.
Thanks
This is actually pretty cool. Probably the most easiest, simple, and safest way to do this out their on the youtube world.
I add a few more brain cells whenever I watch your videos. You're a RUclips treasure for sure.
Hey Thanks for watching.
Awesome video. Wasn't exactly sure how to word what I wanted to search for but I went with the recommended text and this was the first video and it's exactly what I needed. Even explained how much you need for each battery, how to solder to it and everything. Appreciate you!
In most cases, a battery=operated device that runs on 6VDC can be run from a USB wall charger. Yes, it's a lower voltage, but there is a considerable degree of tolerance. General rule of thumb: If it runs on four AA or AAA batteries, a USB wall charger with out output of at least 300-500 mA will work. If you have something that runs on four C or D batteries, you'll want something that can deliver at least 1000 mA (1 amp). Of course, you can use a higher-capacity wall charger in place of a low-capacity charger, but vice versa should be avoided. You might be able to use the USB charger also with 4.5 volt devices (again, some tolerance), but don't try it with lesser voltages.
This opens the door to using power banks to power some devices.
Always always ALWAYS observe polarity requirements, and NEVER use a wall wart that has an AC output to power a DC device. Oddly enough, however, if your device accepts an AC input, you can usually power it with a DC power source of similar voltage. Again, make sure you don't mix that up. If you're not sure, don't try.
This is freaking awesome! I have the exact same issue not wanting to buy batteries every time I want to print some labels and was tinkering about this mod. It’s the exact same model as the one I have. You sir, saved some of my brain cells. Thanks a lot!
Thank you so much. Seriously. 37 year old highschool drop out. This helped me turn my sons hot wheels battery operated car launchers into never dying fun.
That's awesome.
Brilliant idea. I knew I kept all those old transformers for something.
Thanks Man.
Thank GAWD for a non-technical description. You are the bomb!
Good tip, Moe. I do this with battery powered toe nail sanders for pets, but I hard wire them and then I can use them for my modeling hobbies.
Those would come in handy for projects.
I find the best place to get wall wart or adapters is the thrift stores most times people will donate small electronics that require adapters but the thrift store staff don't have the time to put the appropriate adapter with the appropriate item.
That's a great idea.
he even lists all the sources for the materials, thanks dude
Thanks for watching.
Great tip, I've been doing this with my battery powered Dremel tool for several years now.
not appropriate for every item but i love that video showing that the hype for cordless things is not the only way. i dont know how many batteries and energy are wasted this way worldwide, so this is a very good idea. liked and subscribed.
Well said. Thanks Man.
Very clever, get rid of the middleman. I love it!
The little monster has been eating batteries for years. I'm glad I no longer need to worry about it when I pull it out.
Ive been looking for this vid for 4 years. Thanks!
That's a great idea. I was going power the p touch printer with an external rechargeable power bank that has an adjustable voltage. It's easier than to use AA batteries that often leak and don't work when you need to use the device.
That's a good idea.
Thank you! Excellent money saver idea and you did a great job of showing us how to do it.
The EXACT reason I scoured the web! My P Touch Label Maker!
Thanks man. Great video.
Thanks, I'm glad you enjoyed it.
Good idea and nice little hack! Over time, the price of batteries can really add up.
It's just annoying that when I randomly need this every 4 months, the batteries are dead.
It always kind of urked me that devices don't have it to where you can either use batteries or plug it in. It would make it so much nicer if you could plug in something when you don't have batteries for it on hand. Also would reduce the chances of batteries leaking and ruining the device you forgot to take out.
Hi 65, I remember Radio Shack sold an AC adapter that had a little switch built into it to change the voltage. With all the de-vices we have, I would love to get a hold of one of those again.
Amazon still carries them.
Good idea, and I find it interesting that the label maker in question Didn't have a DC adapter port...
Hey Thanks.
Thank you so much for making this video and for your excellent job explaining it in a simple way. Your channel is great!
Always such good content, I don't really have much use for a label maker but if I ever came across the battery type for cheap I would probably snag it, thanks 65.
Thanks Man.
Lol! I've been reusing wallwarts for the "wrong" thing, for years!
I installed a car radio in my toolbox & it is powered by an HP laptop charger.
Another battery gobbling device - No more! Sweet conversion.
Thanks.
Good hack, I hate all the different size batteries
Thanks Shawn.
I was putting batteries in a device right before i watched this, LOL very helpful, thanks Moe!
If I have a device that takes 3 AAA rated at 1.2v= 3.6v. Would any 3.6v transformer work? Is there a threshold on mAh or mA I don't want to go over... Thanks.
Hey Dude! This is one of the better videos on this subject,,,Right to the point, not excess chatter. Good job!
Thanks, I'm glad you liked it.
First video I've seen of yours. Mate, you are what makes RUclips great. Nailed it, thanks 👍
Wow, thanks!
first search for what I was trying to do and you did it. My label printer eats up batteries after 3 labels. Thanks
You just earned a new subscriber,thanks for this educational video,from Balkans,Macedonia
my printer takes 6 AA battery , i was not using it because of this now i have a little DIY project to do, so many other things i will be trasforming thank you so much for this
Awesome, I'm glad you liked it.
Most other similar conversion methods use mock batteries but that’s so much work, why go thru that when this method makes so much more sense? Thank you!
Thanks, I'm glad you liked it.
perfect video! straight and to the point!
Is there something you can use in place of the "wall-wort" to transform the power? for instance, you you wanted to wire it directly into a wall switch.
badass. I'm going to do this to every battery powered device i have.
good video, theres a lot of people out there that dont know about that and this can help.
Thanks Man.
Now I know how to adapt my model kits to a wall plug! Thanks!
i know this is super old but i want to modify my christmas funko village which is basically some dimly lit LED bulbs inside of a santa's cottage (3 different christmas themed buildings)...in following your notes...if i have 3 and each takes 2 AA batts each, does this mean i should opt for a 9v plug and then just run wires to each to solder on like a daisy chain to run all LED lit toys? my only concern is fire safety.... ANY HELP WOULD GREATLY BE APPRECIATED!!!
You could use a 9 volt power supply or a 3 volt. 9 volt you would just wire all the lights in series one after another. 3 volt and you would take a positive and negative wire to each light which is called parallel wiring.
@@sixtyfiveford thank you for responding on such an older video. i appreciate it. so if i go with a 9v just follow your vid and solder batt compartments in line right? if that's right i'm a little confused about the 3v option, sorry electronics is not my forte and i've never soldered anything lol.
Would you consider changing your title to include the words: Brother Label Maker? I serendipitously found your RUclips video while looking for a solution to the battery replacement issue for my PT-70 and PT-M95 Brother label makers. Yours is a nice, simple and cost-effective solution to an everyday annoyance issue. Thanks.
I'm glad the video was helpful.
Does a power adapter have to be used? Could you take an extention cord or cord from a junk item and keep the male end and wire to the device?
Thanks dude, exactly what I was looking for!
No problem!
great idea 65. Sure will save on batteries. I enjoy you videos. You think outside the box. Ray form Ohio.
Thanks Ray. -Moe
How do you choose the adapter amperage when replacing batteries in this fashion? I can't find anything that explains it clearly and this video lends itself well to this question as it covers basically everything involved EXCEPT for current. I assume it matters significantly what output amperage is provided by the adapter used. Thanks.
The device will only pull the amperage it needs. It doesn't matter if you put a 20amp or 1amp power supply behind it if the device only pulls 100mah. You won't ruin the device. A car battery puts out 12volts and upwards or 2000amps or more dead short. But I can turn on my heater that pulls 20amps and my radio that pulls 5amps and everything is happy.
Yep me too . The sony walkman kept me close to home. LOL
I've went through many batteries in Walkmans and Discmans.
Is there a way to be able to leave the batteries in the device also so in case the power goes out, the device can work on battery power without having to put the batteries in the device?
I want to order garland from Bethleham lights from Christmas 🎄 in July 🎄🎄✨️but the beautiful garland is battery operated, and I would rather have a quality item with a plug. I was wondering why they don't put plugs on items anymore ❓️
Good but what if i dont want to solder anything permanently in the battery compartment? Then its not really versatile
I tried doing the same thing but with 24 v battery floor washing machine that uses 100-140 ah batteries. Can u help me out on why it didn't work? It turned on the machine and all but but when I tried running it, it turned off. To it's seems like it's does not produce enough juice to keep on running the machine.
I'd be interested to know how to make that same appliance, in this instance is a nail trimmer for dogs, how to make it more powerful, got any videos on that?
The only way to bump up the power/ speed on little motors is to increase the voltage. So if it runs off 2 battery cells? That's 3 volts. Give it 4-4.5volts and it'll be way more powerful. But you got to be careful because too much voltage and you'll just short it out.
Actually I bought a dc power supply for this I know it's expensive but I can change the voltage anytime I want
Great explanation, exactly what I was looking for! Thanks!
I have an old battery powered dremel that i have jerry rigged to use an RC car liPo battery, but i have no way to adjust the RPMs, can i do this while adding in a rheostat?
Savage!
but what about the eliminator current? I want to use one on a small DC motor, but im worried about the amps drawn. the eliminator im planing to buy gets me 3V but it says its 300mA
Better than buying batteries
Just tired of the batteries being dead whenever I need it.
Thank you sir for sharing 🙏 awesome work...
Nice! Hey brother will that work with a 4.5v battery operated sensor light ?
Great idea.
Thanks Man.
Is there an option to use the car battery instead. How do I reduce the voltage and amperage of a car battery to the same as two AA batteries. I need this for a remote device in the car for controlling the radio volume and changing radio stations. This device uses 2 AA batteries.
You need a simple step down converter like this amzn.to/44IfTkE
Unbelievable easy! Thank you so much. Ive got lights I want to be able to plug in because I forget to unplug them and the batteries go in one night! So for that reason, I dont use the lights I love.
I ALSO JUST SUBSCRIBED! I have a quick fix on a shark vacuum rotor issue I rewired and fixed, and it helped a lot of people also. So, when someone helps me I help them by subscribing to there channel as a thank you! Althea
Thanks!
Thank you four this advice then
Hello
Stumbled across this video looking at how to power a device.
Synopsis: I have the same label printer, it won't work on batteries and it has a mains power point.
I don't have the mains power supply, tried a couple of phone chargers, but worry I fried it due to the unusual central pin.
Question: my label printer won't print, the tape runss out, but the wheel that pushes the tape onto the head doesn't move forward to apply pressure. . . . . Any ideas..?
Thank you for this video. I have a female jack with 3 prongs and no signs what is positive and negative. Any idea how I can tell exactly which is which?
So you put the positive wire in the first positive battery side and negative in the last negative battery side?
Yes.
straight to the point and very helpful! Thank you!
Thanks, I'm glad you liked it.
Goodwill or salvation army is a good place to find power supplies of various values...
Good idea.
Genius. I'm going thru too many D sized batteries on a kerosene pump. Wanting to convert to 12v dc or reg 120v a/c. So 3v but more amps than Ah than AA. Hmmmm
Can you use dead AA batteries instead of making dummy batteries out of wood (Drilling holes and running wires)? What about dead AA Rechargable NiMH batteries? Would the consistent DC voltage damage the unit or cause/damage the batteries to foam/explose?!
Thanks!
I just did this but went the dummy-battery route for a wifi-enabled temperature/humidity sensor. I replaced 3 AAA batteries with an old 4.5v DC adapter but noticed with my multimeter that the adapter was outputting ~5.7v. Should I be worried about frying my device with the increased voltage, or will the load from the device make up for it? I've been reading a bit about adding some resistors/diodes to try dropping the voltage but I'm not sure if that's necessary.
The voltage will drop on the DC adapter once a load is applied.
this is the opposite of what I need I need to know how to make something that needs to be plugged in battery powered
Yup, nothing beats AC to DC. Batteries getting so expensive and then throwing them away. Who disposes of them properly anyways? One thing to point out is output Voltage is important to match but also "AMPs" will effect performance. Largely on power tools. Im converting a 14.4volt power drill. 14 -16 volts OK but requires higher amps.
You would need around 25amps of 14.4v to supply a drill under load.
@@sixtyfiveford - Well 2 years later I went back to validate what I was attempting to do. I gave up modifying my saw until needing it last weekend. My device is actually a 14.4v cordless mini (5 1/2)Skill saw. (Why did I say power drill ??) The battery lists 14.4v 2.5 amps. Going back to your reply - was that a typo? 25 amps?
@@MrGlobaldave1 Yes 25 amps at a minimum. Take a regular circular saw that you plug into the wall. It's going to draw 15 amps at 120 volts. That's equivalent to 1800 watts of power under load. A battery powered circular saw is probably 1/3-1/4 as powerful. That means it needs, let's say 500 watts to run. 500 watts divided by 14.4 volts is equal to 35 amps.
@@sixtyfiveford - Wow - Ok thanks....again! Numbers make sense. I just stumble with the amps the rechargeable battery pack supplied indicates - 2000mah or 2.0 AH
@@MrGlobaldave1 2.0amp hours. Means that battery pack can supply two amps for exactly 1 hour.
2 amps for 1 hour
4 amps for 30 minutes
8 amps for 15 minutes
35 amps for aprox 3-4 minutes
I have a cordless Ryobi tool that uses an 8V rechargable battery. I would love to convert it to a power cord that can plug into the wall because even my new batteries cannot power this tool. Can you tell me how to do that? Thanks!
You won't be able to run it off wall power. The issue is the batteries in power tools are high drain and can produce 15-30 amps to supply the tool under torque. A wall plug adapter at 8v is only going to put out around 1 amp.
I have a 12 V portable fan that plugs into the cigarette lighter in the car and I want to run it off of double a batteries is that possible and how would you do that
Super helpful...thank you!
Great idea, I have that same labeler, went to use it yesterday and what do you know the batteries were dead. LOL! This seems to be a regular occurrence with the labeler since I only use it every now and then.
I only pull it out every 4 months or so and the batteries seam like they're dead every time.
Rite, same here the power adapter is a perfect solution. I just stuck 4 AA batteries in mine yesterday to make 2 labels. LOL!
That looked factory when it was done! cool good tip.
Hey Thanks.
Is there a way to rig up something that uses 3 (357) type batteries? I have a decorative porcelain Christmas snowman that uses 3 small batteries & only 1 coil. Any way to add a plug to this?
If the batteries are run in series/end the end then you'll need 4.5v to run it (3x 1.5v). There's always enough leeway in battery operated stuff to go up a little or down in voltage. 5 volts is very common won't damage your lights, so i would choose to run it off 5 volts. You can get pretty much any usb power supply (phone charger) and it'll supply 5v. You could make it plug in or even run it off a cheap power bank.
That is one brilliant idea. Thanks again.
This thing and batteries has driven me nuts for years. I use it once every 4 months and every-time the batteries are drained.
sixtyfiveford
I know exactly what you mean!
Does anyone know what those red and black cords or wires are called
Great idea! I take it you don't need to care about the output current of the charger? (I assume the device will only take the current it wants)
chr11sf if the maximum output of the charger is higher than the maximum possibly consumed from the tool yes. it won't work for a cordless drill for example. there are some needing 20 Amps and more.
It will only pull what it needs from the transformer.
Quick and easy!! Thanks Moe!! Zip~
Thanks.
would anyone know how to do this with 3 AAA batteries? do i need two black wires and one red? two reds and one black? and do i solter to the minus (-) or plus (+) side?
That's a nice work around.
Thanks.
Great Video! 2 simple questions hopefully if you can answer for me that i feel seemed missing in the video....
1. How did you determine the positive and negative tabs on the unit or what would be the best way to do that.
2. If i have a unit that takes 3 AA batteries, will i still be soldering to just two tabs for positive and negative?
thanks so much!
Negative and Positive were determined by the battery orientation. With 3 cells laying side by side they are both connected to the center battery so it's just a chain of 3 batteries end to end. Look closely and you should be able to determine which end is your final positive and negative. A multimeter makes it easy but external visual inspection or opening the device both work.
can you do this on tablets? specially bed-mounted tablets. battery is a pain
Can you still do this kinda set up on battery power Halloween/Christmas lights?
Absolutely.
i got an oldschool sd card mp3 player for my night time music which uses an aaa battery but it runs out in like 2-3 nights so yea thx for this tutorial and goodbye waste of batteries :D
Awesome
hai, what is the different between transformer and adaptor??
let say, if i want to by-pass my phone battery connected directly to wire can i use this method?? do i need to buy transformer or adaptor that have the same volts like my phone battery volts??
enjoyed the video. I want to make one of these to run a dc fuel pump. I have some power inverters around. can I just splice one in to my dc pump using it's clamps and will this handle my project? usually I hook my dc pump up directly to my truck battery but have to keep the truck running to get enough power and it's to loud. thank you for your assistance.
You'll need a 10-15amp power supply to keep a fuel pump running. Probably the easiest way is to just run it off of an old car battery charger.
@@sixtyfiveford thanks for the reply. would I just hook the alligator clips together and turn it on? after making sure it's set for the right amps of course.
Hi there, I know this is an older video at this point, so you might not see this comment, but how would I do the opposite? I have a small clock that plugs into the wall that would be much more convenient to have with batteries instead.
