I'm doing this research to power a motion-sensing outdoor light that for some reason is powered by batteries and doesn't offer an adapter option. Notes to people attempting such a mod, battery compartments could be in series or parallel or a combination. Like, 4 AA batteries could output 1.5v in parallel or 6v in series or something in between. Also, consider the resistor you need to replicate the batteries' resistances. I think a AA battery has about 0.1 ohms. I suppose the adapter may account for that, but for delicate electronics I would want to cover all my bases. Its one thing to convert an outlet-powered device to using batteries, its a whole other to do the opposite. Don't burn your house down.

Nice job, and well worth avoiding frequent battery changes! Maybe some ideas for future videos: Sometimes instead of an A.C. adapter, I'll use a battery holder for larger batteries. I.e. your 3x AA decoration will likely run for weeks on 3x D cells, which could get you thru the season without changing batteries. If 3 AA rechargeable don't work well, 4x might do better. Another option is a USB powerbank. 4.5v being "close enough" to the 5v put out by said USB powerbank, just wire it up like an adapter, but now you have a big battery. Final option if you know how to safely work with "raw" LiIon cells, 4.5v is "close enough" to use a single 4v LiIon cell with a simple single-cell BMS and TP4056 charger module (get one with "battery" and "load" terminals and wire the decoration as the "load" so the board can turn it off when the battery is depleted). I lied, there are more options but they get more complex. Such as using a LM2576 step down (or "buck") DC:DC converter connected to a power tool battery and adjusted to output the desired voltage for the gadget.

Great video. Goodwills are a great way to source the adapters. Batteries are way too expensive to keep replacing them for these sort of things. One thing to note is how many milliamps the power supply outputs too. A 1000mA unit is ideal for anything that has a larger load. Some phone chargers only output .1mA and sometimes that isn’t enough current to run certain items.

Hi Chris - in general, with lower volt stuff, being within 1 volt or so of the intended target is fine. So, if you have a device that uses 3 * 1.5v batteries, using a 5v supply will be fine (It's 0.5v more than batteries provide, but won't hurt anything). As for amps: Remember that volts are supplied, amps are pulled. So the amps will be drawn by the load - i.e, the device you power will determine how many amps are drawn. Again with low volt stuff, most things pull only a very small amount of current - on the order of a few milliamps. As long as your power supply is has a higher amperage rating than your load will pull, you'll be fine. Thanks for watching!

Yes, stick with the same voltage, and grab an adapter with a little higher amperage rating. The length of the wire can affect how much voltage drop there is... but if it's just a few feet it should not matter. If you are planning to do more than, say, 15-20' though, then you really should just get a separate adapter and wire them separately. Assuming you are trying to convert a little 5V thing, you'll have too much voltage drop due to the internal resistance of the wires. If you are only adding less than 10' though, don't worry about it.

Great question, David! Each string needs 3V, so you'd only need a 3V adapter even to run all 3. The voltage does not need to go up with the adapter, but the ability to supply amps will need to increase, as each string will pull a certain number of amps. I'm guessing that each string pulls less than 500 milliamps @ 3V, so if you had a power supply capable of at least 1500 milliamps (or 1.5 amps) then you'd be just fine. You should have no problem finding a power supply that can handle 2+ amps at 3V. Good luck!

Heya Android:55 - AAA batteries provide around 1.5v each, so with 2 you'll need a power supply that can put out 3 volts. Here is an Amazon affiliate link for one that would work well: amzn.to/3LZ28ni - though you may also be able to find one at your local thrift store, if you have the patience to do some digging. Good luck!

I dont know how dangerous 4.5volts is 😅 could maybe pop a capacitor in the dc power supply if you short it maybe. But you should also check how many amps you need. It's also good to check if rhe batteries are series or paralell. As 2 batteries may not mean it takss 3volts. It may be 1.5v using multiple batteries for higher amperage.
