Oh this is brilliant, thank you for sharing. I have found the exact same in UK version just in time for Christmas. I was about to get my mum's soldering kit out after watching some other videos but this is perfect!
I bought several of these for the flameless candles and Christmas decorations around the house! It's an investment up front, but will pay off in the long run!
There are AC adapters with adjustable voltages and aren't too expensive, and it can change between 3v, 4.5v, and 6v, which would be 2, 3, and 4 batteries. You can also change out the connector. What I do is just the micro-USB connector, and then solder a micro-USB female connector to the battery terminal of the device, and then I can just plug the wall adapter into it and it'll work.
Yea Todd. Luv your video. I'm 83, a computer technician, and you helped me immensely because I have a Roku device that keeps eating AAA batteries since I watch tv about 7 hours a day now. Lennick doesn't show AAA but because of you I found Gersen that makes one.. You are top notch presenter. I love way you speak. You don't race your sentances like lot of tech people. I like you better than Carey Holzman, vblogs, who has great sense of humor, but drinks coke all the time. Very distracting.
A genius of an idea. So simple yet so well applied. The dummy batteries supplied are just the electrical connection. The first cell is just completing the circuit. The second one with the strip is connecting plus and minus with those of the eliminator with an insulator surface in between. Great.
Brilliant !!!, I love your implementation to this problem. I Actually asked myself why there anything that can imitate batteries and allow you to use the power outlet to power battery only devices. I will recommend it to anyone I know.
Thank you for this video. I found this product on Amazon and was wondering if anyone reviewed it. I have a vacuum pump that uses 8 AA batteries that I just replaced after 13 days of use. Ridiculous! Can't wait to receive my order.
Hi! Do you know if these will work for a 4AA-powered microchip cat door? I read that there may be some issue with the amount of power needed for the microchip operation. I guess I could just get one and try. So tired of replacing batteries!
Great idea lad, Even with big or small MP3 players might work this way. Even if you find a AAA (Triple A) Battery eliminator powered adapter might even work with battery powered MP3 Players.
Been ,only today looking for same ..but please which of the 2 batteries are connected?? And why?can't I use aluminum foil to make wafer connection..to plug in
Do you have a video regarding changing out the batteries to wall power for an electric recliner, couch and love seat? My batteries do not last long at all and are very expensive to replace. Plus, they take about 9 hours to fully charge. We did not realize this when we bought the set of expensive sofas and recliner which are indeed a real problem if the battery dies when you are sitting back in the recliner or sofa and can't get out of the darn thing because the battery died. Thanks.
So does the power supply need to be slightly higher than the required voltage. You need 3 Volts but it's 3.3 voltage adapter. Will just a 3 voltage adapter work just as well or does start losing power through the wire? What happens if it only requires 3 volts but the adapter is 6 volts does it fry the circuitry? I think I'm going to need the thing you just showed because drilling a hole in it will definitely affect it. It's a battery powered wet/dry razor. I go through batteries like a madman. I have a chargeable Norelco the 3 little round head type but I get a much better shave with the Braun signal foil razor. Don't know why but it's always been that way. A drilled hole would ruin the waterproofing. I'll see if you followed this one with a hard wiring video, of course that still leaves me with the same problem. I'm horrible with electronics.
I love having this option, but is there a less expensive route? Using your own AC adapter by connecting it to the terminals inside the battery compartment would work, but would that be any less expensive? I imagine the ac adapter would be $5-10 at least and then getting that ribbon like cord would also cost at least 5. So do you think there is any savings? Only thing that might be a big saver is if you can daisy chain something together, like flameless candles. I'd really love to be able to do that.
Thanks for the video! I have a basketball hoop in my room. It tells you your score, but its battery operated, and it eats my battery's up. I found this item online, but I wasn't sure if it works. I searched it up, and I found this video. I will definitely get this at some point.
I'll be seeing if I can convert most of my Halloween battery powder items to power for next year... thanks alot... better than splicing and finding the right powdered adaptors to convert.
What about if the item I'm lighting is outside and there is no electrical outlet near by, WHAT CAN I DO. I have 2 holly trees with fairy light on a timer. I have to change batteries about a month and 1,/2, I have lights on fading mode, Theres no Electrical outlets as trees are on butter corners of my house
I was thinking about doing something like this with one of those little portable bluetooth speakers, but I'm worried about amps. The current battery is a 3.7v 2400(ish)milli amp. The 3.7v wall adapter I have is something like 2-4 amps.
Hey man I am surprised to see your comment... just abuot hour ago i was planning the same and just started searching for youtube vids... i think we can collaborate... :)
@@simplyboymohim5911 The best I can come up with right now is to just grab a 3.7v adaptor and wire it up to see how it goes. Worst case, you're out a speaker that costs like $5 on ebay.
You should try to match the amps as close as possible. Yes it will work with larger amps. BUT any unused amps are converted to heat. Which could cause fire, or early blown parts due to overheating. You notice he says at the end 'I noticed it's alot brighter as well' this is the additional amperage.
Gary, Yes! Look in my video description. You will need to purchase the "C" battery adapters along with the "AA" product. They will fit into the "C' battery adapters to make it work :) -Todd
In most cases this will work indeed. However in some cases, devices use batteries by design because electricity coming from AC to DC conversion will make the device not work properly. The AC/DC conversion is never that clean compared to a pure battery, some left over of the changing voltage will be in the low voltage and on top of that, the wires might act as an antenna and pick up signals that might interfere with the electronics in the device.
Todd: Do you know what "class" wall wart/ac adapter that unit is? Ideally class V or VI (dunno if there is a class VII yet) because they are supposed to be very efficient ~95% (under certain conditions). If the unit is taking only fractions of a watt if the powered device is OFF, that's ideal. The older wall warts were terrible, but some govmint standards changed that over time. The manufacturers don't make it easy to read the specs on the case. You kind need your reading glasses and a bright light. Thanks in advance! Cal
Queries being how many va should the transformer be I plan to scavenge a 1.5 volt transformer and solder or make dummy battery's with hot and ground end s and basicaly Daisy chain in parelell there silly clip on the tree Christmas things outa China but I Wana convert it all to line volt to work off the remote
@@twHomeShow ignore him, you did a great job on this video, , im using this w 2 D batteries for my tank less water that hangs on the wall in my garage. good tip to leave some slack of the cord in the battery compartment so you dont stress the cord too much too.
1 year ago wow, but I must say that if u got a portable 2 AA device , if u put this wit an attached device u will not have a portable device anymore. I was searching this a year ago now I use buck converters and a lion battery to keep that portable

Much thanks,having great difficulty finding an adapter,for a portable radio.

Well a replacement battery pack for a Dysart v6 vacuum cost 100$
2:01 were you able to to make the alternative method described here?
Thank you for your help.
That's pretty cool, I was looking up how to do it the hard way, but I'm not confident in my electrical capabilities and this is so much easier.
Awesome! Glad you found this video.... Todd

Can you review the C battery size ones? I looked them up on Amazon via your link, and they were different from the ones you used.

Awe ! I was waiting for it all to go BANG.
Sorry another quick question
If the batteries are the same voltage why are they different sizes?
Good question! I believe it may be the longevity difference of each different size. -Todd

Will it work with 4 batteries
Great hack! Do you have a video to convert battery power to USB plug power?
No I don't. But that's a great idea!
I want to change from a 2 d-cell to electric for my Propane tankless hot water heater
Got one that does four AA to usb so i can use a power-bank to run an audio device
Thank you for the video. Right what I need. The idea came up in my mind and I did some research, but most of the results are 1.5v to ac
Glad it was helpful!
Please let me know how to convery my rechargable battery operated kareoke maxhine to direct power supply

That is so nice to hear. HAPPY NEW YEAR! I thank you for your nice comment. Todd
Cool to know! What I would like to know is if it can be done with those flat lithium flat 3V batteries (CR2032) ? Thanks
What if i need 6 batteries do i need two?
Cool sign thanks
