SAVE $100s on batteries with this simple decorating hack

If you like to decorate with fairy lights, flameless candles, or any other battery device, you can hack those devices to be powered from a simple USB charger and save hundreds of dollars on batteries. USB chargers output 5 volts, which is roughly the same as 3 AA or AAA batteries. Most decorations with 3 batteries will probably work with 5 volts. Don't waste money on batteries in decorations.

You and me have an all together different idea of what “simple “ means.

Great work. I have found my peace with rechargeable Eneloop batteries. 21 years ago (!!!) I bought 48 AA and 16 AAA cells. With a storage box and 8-way charger. (All together it cost about $200) Eneloops do not discharge, the whole family has got used to it, puts the empty batteries in the charger, the charged ones in the box and I have not bought such a single AA/AAA cell for over two decades! With all the children's toys the battery consumption is extremely high, I would definitely pay $10 a week for disposable batteries. In 21 years I have easily saved $5000.

Extra points for demonstrating an *actual* hack and not just “watch me use an out of the box product in a slightly unusual way.” This is genius.

Your hack has easy to hide wires. Much better than bulky battery packs! I’m saving this for future reference. Thank you!

Your wife's decorating is very nice.

Did something like this to power an LED Christmas star for the top of our Christmas tree. Very gratifying to see star go through all it's colors without having to replace expensive batteries.😊

I make delicate indoor fairy houses and struggle with making the bulky and heavy battery packs being discreet. This is an ingenious hack. Ty so much! Merry Christmas.

I love the fact that you connected it all with a Wego. You can add and remove super easy in the future. Nice

Would love a longer step by step on this or similar!

I added a 1N4001 power diode i series with the positive. They are good for 1 amp. They give a approx 0.6 volt voltage drop so the lights are getting the correct voltage. They are operate differently from a resistor so they don't get hot. For a light that has 2 batteries that give 3 V I put 3 diodes in series. Works very good.

[teslatrooper]

Just checking for a few seconds for the voltage might not be conclusive. Most LEDs will work with overvoltage, but it greatly reduces the lifetime. Adding a series diode will reduce the voltage by 0.6-0.7V and will have almost ideal voltage.

This will change my Christmas life. Thank YOU!!!

Beautiful decorations. Thank you for the hack!!

it's not really wasting batteries if they are rechargeable, though. I just bought a bunch and rotate them out from charger to lights. It IS WAY less of a hassle to not have to do that, though! Now, I have to learn how to solder, lol.

[sonjacarrizosa]

I love it! I am getting into electrical now nd just touched on circuit boards. No schooling just YouTube and maybe wiki how…..I love how simple you made it including the error! Thank you so much I’ll be watching much more of your channel.😊

Great idea! Save our environment and our money too. Thank you for sharing. Happy Holidays! ❤

Okay, guys my dad taught me how to do a lot of DIY including rewiring a lamp. That was it for electrical!
I have long wondered if there was a way to convert battery lites to plug in!
Can someone either do a deep visual video step by step how to do this. Or even better yet invent the conversion and sell it so we non-electrical folks can easily do this! Thank you 😊

Nice hack, the rechargeables you start with are ~1.2v each BTW. There's a small chance the 5v may over-drive the LEDs - but since it looks like you are powering 4 strings off of one usb cube, this should lower the overall voltage. Make sure the USB cube doesn't get too hot to the touch!

[metajock]

Good vid. I knew this could be done, but big thanks for showing it so clearly.

You’re a genius! Thank you! Merry Christmas! John 3:16❤
