Exactly what I got on youtube looking for. Same cheap lights from amazon but ours dont have the LED covers like yours. Since LEDs do no let off heat I put these lights behind a HotRod car picture frame in my son's room. He uses it as a night light and ALWAYS forgets to turn it off. (he never puts it in auto-off mode) This is really going to help!! Thanks for putting this up!!
This is very informative. I need to convert small battery operated lighted houses.
Great video, the instructions are very clear, and the explanation is very clear. Thank you very much for sharing this information.
Good video. One tip....if you have an Android style cable, use it instead. They are a dime a dozen. I hate using my precious iphone cable. Also, just two wires in the android charger. Red and black. Real simple. I converted a 3 volt supply (2 double A's) to this 5 volt system, and it worked great. And a plus is that the bulbs are 2 volts brighter. lol. Good video.
Hey do you know if it is possible to by-pass the battery holder completely? I don't need any of the functionality...just the ability to turn them on when I plug in.
@@ulicornprocreateartclub2617 Here's one example: th-cam.com/video/gJKy20wfIvg/w-d-xo.html
Do you know how to convert a 8 unit battery powered puck light system into a 110 volt system? I need to also know which amp converter I need. Each puck takes 3 AAA batteries.
Thanks I am going to try this before asking my hubby, I think I can!!!!
@@ulicornprocreateartclub2617 I tried doing that and it burned out my lights in seconds. I think there's a volt regulator that the LEDs need in the battery box. If you figured it out, let me know please.
Thank you for sharing I appreciate your expertise!
clean job explaining things. PLEASE include a short explanation somewhere about voltage and why 5v is sufficient for this. People who dont understand will try something like this and ruin their electronics..
okay steven this is exactly what I was looking for, please let me know in the comments how to know what kind of power is enough! also, it seems to me that he only took a usb charger and connected the strings to the battery box? are all chargers for phones 5V?
@@johhnycash1515 Yes, USB is limited to 5v.
@@johhnycash1515 AA, AAA, C & D are all 1.5v batteries. A USB charger (5v max) will suffice for any set that has 3-4 of any of these battery types.
HI, thank you for this 🤗. can we do this to connect it to a low voltage landscape transformer?
Great video 👏👏 Can you please share the shopping link to those lights? I love them. Thank you 🤗
how do you know which one is the possitive and the negative on the battery box and the usb or carger adapter?
Thanks. Exactly what I was looking for
Me too! Thank God!
Thanks!
To add another dimension, could I add the lower voltage fairy light string to a 12V AC circuit (that powers 12V UV SMD LED light string) if I also added a buck converter (or voltage limiter of some type) to have a seperate light inside an eternity mirror? Ie., I am making an eternity mirror as a gift and just can't figure out how to use the fairy lights for the detail at the center of the mirror without blowing every LED. There are no variables to the fairy lights - there is only a resistor in the battery box since it is a simple on/off controller - and I have an inline buck converter that drops voltage to 5V. The wall adapter is a 5-12V AC to DC source, but I know from experience that the adapter is not a regulator, and having 2 power sources is not gonna be aesthetically pleasing.
Any ideas or am I on the right track?
Thanks again! I am planning to do just what you describe for a other lighted gift now!!!
I would be tempted to add a female connector to the battery terminals so that the usb male connector could just be plugged in rather than soldered. This was a nice explanation of the task.
This worked for me on the mini led xmas lights, thnx.
Thanks for sharing
I wish I could do it
God bless you more
Two years late lol but will this work with any light device that’s 5V? I bought my brother a blue LED lightning bolt thing for his desk, but I didn’t know it required 3AA batteries. The thing dies every third day as he just leaves it on.
It’s only going to be used as a desk ornament, so we don’t need the portability. If I use the same iPhone wire and phone block adapter as you used, will I need any additional resistors/capacitors?
USB cable...BRILLIANT! Never thought about it but yes, that is the perfect solution [I think! LOL]
I agree! I'd been thinking to do it I'd have to figure out how to work with resistors, or something, to lower the power from the outlet to whatever the light string needs. I guess it's still dependent on finding a light string that needs right around 5 volts, but that's hopefully not too hard.
Got a quick questions. My wife has 3 candles on the mantel above the fireplace all 3 take 3 AA batteries. I'm tired of buying batteries, what would be the best option to convert these with the lease amount of wires running everywere?
Can I hook up a 12 volt power supply and tee off to all three of the candles? Will be short 1.5 Volts but will it work? If I only hooked up 2 candles I will only need 9 volts will a 12 volt power supply push to much beings there is 4 volts left?
I have 2 battery powered LED lights. They have 3 leds and a small motor, running off 3 AA (4.5V in total) batteries. If I were to wire both of these up to the same power source, would I need anything besides the 9V AC adapter? Would I need to add a resistor or are there resistors inside AC adapters? I'm new to this, so please forgive my rookie questions.
Can I tap another set of lights on the other side so they will use only 1 plug?
Very informative very helpful that's obe jib for tomorrow 👌👌👌
I have a question. I have 4 seperate lights. Each powered by 2 AA batteries (3V)? I want to power all 4 from one AC adaptor and switch.
So do I need a 12 V dc adaptor? How do I wire them so I’m not feeding 12V to each light and I’m sharing the 12V between all 4 lights?
Thanks.
So I've got two strands that take take 2 AA batteries each. Obviously I can connect each one to a 3V transformer but what if I want to connect the stands together? Would i still use a 3V or would I need a 6V?
This is great! Any chance you would do some similar with one of those stupid battery-power Xmas village house. 😁
I bought string led it cames up using 3 battery of lr44 and its ran out reallt quickly, can i tell be how to converr it using usb for powerbank or phone charging.. is it the same tutorial ?
What if I want to daisy chain two or more strands?
I have not soldered before. It will be helpful if you show how exactly to do that.
I used a wall wart from my old electric screwdriver. 5 volts.
Is there any potential for fire doing it this way?
my charger is 5.0V at 2000mA is will this blow up my led christmas tree star that only needs 4.5V @ 1000mA?
How are you able to regulate the voltage
I want to covert 7 different Christmas village houses that are battery operated. Most of them have 3 battery each. I would like to convert them to electrical. I would like to have them go into a USB hub.Does anyone know what kind of USB hub I need to buy and what voltage. What does USB 2.07 and USB 3.0 mean when buying a USB hub. Any help you can give me would be greatly appreciated. Thanks for any help you can give me.
Thanks! Did it to my lights too.
would this setup work on item runnin on just 1 or 2 AA's? Got a big Christmas village & some of street lights only run on batt (no dc adapter outlet. Pain constantly replacing batteries if left on or turning off/on to match rest that's on a timer. Thx, Jerry
The connection would be the same.
Your just need an adjustable power adapter that has an input of 110V (if US) or 220V (if Europe) and an output of 1.5V (for single battery) or 3V (for 2 batterries).
Here is an example of such a power adapter.

Great idea, thanks for sharing. The dollar store started carrying fairly powerful LED floodlights that are battery powered. Will attempt converting those into plug-in lights using dollar store chargers and cables. Work lights for under 10 bux!
Could you connect several of those light sets in series with the same 5v adapter?
I would also like to know the answer to this
Melissa May
“Series” would drop the voltage to far.
It would need to be in parallel so each string would see the 5 volts and make sure you don’t draw more current than you USB power supply can give. Most USB power supply’s can do 1 amp some can even do 2.4 (iPad chargers)
I found 5m string lights with a remote and it has settings connected to the battery box that will make it change 8 different flashing patterns with a timer. Is there a way to convert something like this to USB or is it too hard to do?
none of that matters. this is just a power source.
Dear DIY Creator, need some help. I tried something similar. I had a night light sensor with three AAA 1.5 batteries. I used a mobile charger (about 5v) which takes type A USB which connects to the charger while I cut the other end C usb. Found the live and neutral (in my case Red and Black as white and green were data) and soldered them to a common connection on the night light. BUT what happened is that the LEDs light alright but they do not go off. I tried the batteries again without the charger and worked OK. Can you tell me what I did wrong. According to the multimeter the reading was 4.9V. Any help pls?
My guess is you somehow bypassed the sensor portion of the light. The sensor is supposed to act like a switch, turning the lights on (supplying power) only when needed, but you seem to be supplying power all the time. So you probably just connected the hot wire at the wrong location.
AWESOME FIRST VIDEO, NEW SUBBIE HERE. CHRISTINA
cool!
I want to do the same thing to a Puck Light that is operated buy 3 AAA batteries. How do I know what voltage of phone charger USB I need?
Each AAA battery is 1.5V, so 3 AAA batteries would provide 4.5V (3 x 1.5 = 4.5). All USB charging adapters provide 5Vdc, but their output current can vary between 500mA (0.5A) to 3.0A. If your puck light has LEDs, then even the older 500mA chargers will be OK to use.
Most newer chargers have the higher current capability. They all should have a label indicating 5Vdc output and also their current.
@@norcalkid2776 god bless you sir, thank you.
It is so weird that I was looking to learn this for the exact thing that you used ( the lights from amazon) but I was wondering can I use plug of any old christmas lights instead of a usb cable?
No. What's coming out of your christmas light plug is 110v AC. You need the usb charger to convert from 110vAC to 5vDC. Connecting the 110vAC directly will at least cause smoke or damage to the components.
This video is for simple 3 battery configurations... 1.5v+1.5v+1.5v=4.5v
USB=5v
Not equal, sure. But a great hack for cheap lights.
Aren’t you afraid of the higher Amper produced by the charger than by the batteries? Will it not harm the led?
Amps are drawn, not pushed. So as long as you have more than 1 amp, you should be fine. In fact, the power supply could be rated at 50 amps and you would be fine, too.
Can I use this hack to power a device that uses only 2 AA batteries? (That is, 3V)
Maria Vitoria Di Bonesso Hi, were you able to do the same thing for only 3V?
Should add a fuse inline. Better safe than sorry
Does anyone know how to wire several light strings to the same plug?
I wouldn't do this with a 5v phone charger. It would lessen the output to each set of lights, the more you added... each set of lights needs at least 2 AA batteries (3v)... maybe a 12v cable would work for eg. 4-5 light sets that'd usually require 2 AA batteries OR for 3 light sets that'd require 3 AA's 👍
Also, I would test which wires are pos & neg in all of them before soldering anything (not solder as you go) coz testing a neg on a pos bunch may short circut the lot already soldered on 😬
Just came here to find a cheap way to light a dollhouse. That’ll do rabbit, that’ll do. ✌🏻
Well, I tried to replace batteries with wall transformer (here in US from 110 to 4.5 DC) it fried the chip ! connected DIRECTLY a to string of LED's and only half lighted up ! anyone know how to make all of them light by wall adapter ?
Appreciate d, thanks
WARNING! Does not work!! Fried my led lights after 1 min.
SOLDER.....not SODDER
This did NOT work. It only ruined the leds.
