How To: Convert a light from AAA Batteries to USB Battery pack!

  • Follow along as I convert a AAA battery powered camping light to a rechargeable USB battery pack powered light! Think it'll work?
    I bought some of these great little lights at Walmart to run in my Otter Vortex Lodge ice fishing hub & the only thing I don't like is that they get dim after a while. They don't seem to have a lot of longevity with the AAA batteries. Since rechargeable USB battery packs (and most USB power sources) have a 5v output, I figured that's close enough to the 4.5v the AAA batteries put out. I should be able to run the light off the charger without damage...right? 🤔😉

    USB cables don't always use the "correct" colors on the inner wires, it's good practice to check with a multimeter to be sure. The fuzzy stuff in there is strain relief, the idea being if the wire gets pulled, those fuzzy strands get tugged instead of the actual inner wires themselves. Voltage being correct is important. Alkaline batteries will have a max voltage when new of 1.65V and are "empty" at around 0.7-0.8V. That means devices that use 3 AA are expecting an operating voltage in the range of 2.1-4.95V and 4 battery devices work with voltages of 2.8-6.6V. So, a USB 5v supply will be fine "as-is" for most 3 or 4 cell devices. There is also the caveat that some devices will rely on the low current capabilities of alkaline cells in place of having current limiting built into the circuit, so the ability of a USB to supply higher current can potentially fry some circuits if you don't also add an appropriate resistor in series. You can measure the current draw with a multimeter using fresh alkaline cells to figure out what max current the device is expecting.

    I'd suggest getting a usbc power connector so you can unplug it. I don't know where I've seen it but it sounds like the best idea.
    A chip with USBC connector and various power outputs, just sodder the correct one, depending on the requirements of the device.
    That way you can replace the cable effortless and easily swap devices around in your household.

      Mint, Bee Dub! You should wire in an LED fan indicator on the heater, too! I added one to mine & it's so helpful when I use it! I used to accidentally leave the fan on all the time, killing the battery (I wired in an SLA 6v).

    I like your thinking. It should be noted to check if the batteries are in series or paralell. In series the voltage is multiplied by the number of batteries and rated capacity remains the same; in paralell the capacity is multiplied by number of batteries and voltage will remain the same.

    • @EndlessDIY
      @EndlessDIY  2 роки тому +2

      I'd say that's probably correct. I think the 1/2v difference is probably negligible enough but since these lights are only a couple bucks, I'm willing to take the chance. I have recommended in replies to commenters that it'd be wise to do some research before performing his mod on something they're not willing to potentially sacrifice. 👍

    Another thing you could have done with the wire inside so it can't be pulled out, just wrap about 5 layers of black tape on the inside so it can't be pulled out. Or, at least not easily. The tape just has to be slightly larger diameter than your hole you made for the wires.

    An informative video and well done. However, the "bare wires" you gathered together and twisted into one wire, are actually the "shield" for the cable. These wires protect the four wires inside from outside interference known as eddy currents. You should have used the red (VCC+) and the black (GND or negative lead).

    I'm using a simple LED head lamp as with age I do need more light for some tasks. Actually I have a few of these Using 3x AAA batteries I found these otherwise super helpful head lamps not sustainable. So naturally I wanted something USB chargeable but why spend £15-25 on new head lamps when mine do work and I have all the required equipment laying around as I consider myself the DIY and recycle queen.
    I used a long micro USB charging cable and converted my LED light to a USB via power bank or mains powered light. Very pleased with myself right now. One done, a few ore to go, I even consider installing some plug in options.

      Hi there! If your soldering iron came as a kit, it may have some solder with it. If not, you can pick up solder at any hardware store. Just make sure it's not plumbing solder. ;) You can get high gauge (higher the number, finer the wire) electrical wire there, too, or even take apart something you don't use or that's broken. I salvage a lot of my electrical goodies from broken things. There is fine wire in iPhone cords or anything like that. Thanks for watching & good luck with your projects! :)

    Great hack! Question: Does the size of the power bank matter? Since the fairy lights will only drawl the amount of electricity it needs to light up, will it harm the fairy lights if it is hooked up to a bigger power bank that has fast charging capabilities? Or will it require a power bank that has limited output of only 4.5-5.0 volts?

      @EndlessDIY  Рік тому

      I guess I don't know the math. I've used different power packs with the lights and the only thing I've noticed is how long they stay lit. My big Anker pack has a standard and a "quick" charge port on it. I've used both & haven't noticed anything. Take that anecdotal bit with a grain of salt, though. You might have to do some Googling to verify the numbers. Ohm's law would probably get you started.

      Sorry for the late reply, I haven't been getting notifications for some reason & the comments really piled up! The conversion removes the batteries altogether and replaces them with a cord so you can plug it into a USB charger. If the charger (or light) has a switch you can just turn it off.

    • @EndlessDIY
      @EndlessDIY  2 роки тому +1

      I don't specifically but if you look at the battery, you'll see the voltage (generally 1.5V). Depending on how many it takes to power your device, you may be able to convert it to a USB. Just add the voltage together to determine if 5V is enough to power the light or whatever you're converting. It doesn't need to be exact, just in the ballpark. It's the same process as this video.

      @@po1395 It really depends on the device. There's always a little wiggle room for variation but it depends. I'm no electrical guru so you might want to look up acceptable voltage variation for your specific device.

    Hi,
    Can you please show how to convert a AAA battery device into a dual mode device using direct AC power for power adapter and during power outage for it to auto run using rechargable battery connection.
    This I was thinking for a Aquarium fish feeder. So that the timer does not get reset during power outage.
    Other advantage is the durability of rechargeable batteries like Lithium will increase during to non extensive usage.
    Thanks.

    I tried this but unfortunately batteries run at a much lower amperage than usbs do. I think it was about .1 amps while the lowest a usb will run is 1 amp 2.1 if its an old android charger. This means the electronics will run much hotter and potentially burn out. I'm gonna see if I can find a resistor that'll drop down the voltage cause as it stands I'm liable to burn a component.

    • @hotrodsurplus
      @hotrodsurplus Рік тому

      There is no such thing as excessive current (amps) in this case. The device will simply consume only the current that it needs. Now voltage is a different animal. Excessive voltage can wipe out a driver board and LEDs. That's when you need a regulator of some sort.
      But a separate regulator is not usually required in these cases. Three fresh alkaline batteries can put out 4.5 volts whereas a USB wall wart puts out around 5.1V. The .6V difference usually doesn't cause problems as the driver boards in most of these devices have some wiggle room to handle a little excess voltage.

      That's a great question. Unfortunately, I don't know for sure. I'd be especially careful when it comes to medical equipment. You might look up what the variation in voltage is for the meter and the charger. If they're within the limits, it _may_ be ok, but again, I'd be especially careful. I'm sure that meter isn't cheap to replace. I hope you find what you're looking for and good luck with your project! :)

    • @EndlessDIY
      @EndlessDIY  2 роки тому +1

      AAA batteries are 1.5v each so 3 of them equals 4.5v, which, in my experience is close enough. Devices are almost always able to handle some voltage swings, so 1/2v probably isn't a big deal. If your fairy lights take 3 AAA, it _should_ be fine, but I can't guarantee it. If you're worried you might want to do some additional research on a site like Sparkfun or similar.

    HELP please? This is quite helpful, as I wanted to do something very similar with a light in my computer desk to brighten it up. PROBLEM IS -- it won't light up sufficiently like the batteries do. I used a voltmeter to find which wires were the power (they weren't the traditional red/black ones), soldered them to the right contacts (I don't want to use batteries again), and tried several different power sources (4 wall chargers with different amperages, and two computer USB ports.) The light won't light up when plugged into any of the wall chargers: and when plugged into the pc usb ports, it strobes a couple times, and then stays rather dim. I don't know enough about this stuff to troubleshoot it myself. Anyone have any suggestions?

    • @EndlessDIY
      @EndlessDIY  3 роки тому +1

      Hi there, I would guess the most likely issue is that your light takes more power than the USB ports can provide. Generally, USB provides 5v or power (some can provide more, but from what I understand, they're designed specifically for that purpose). While my little light originally took 3 AAA batteries @ 1.5v each for a total of 4.5v, the 5v USB is close enough. If your light is supposed to run on, say 12v, the USB just won't have enough "oomph" to run it. You can see what it's supposed to run at by looking on the batteries. Each one will tell you what the output is then multiply that by the number of batteries.
      Another possible issue is that if it's not a dimmable light, being even slightly underpowered might cause them to flicker.
      I'm no electrician but I hope that helps! :)

      The British pronunciation is just sounding it out the way it is spelled.
      I'm from the UK, but I live in America now. I have lived here for 15 years, and I have adopted most American English pronunciations (including 'aluminum') but I can't quite bring myself to adopt 'sodder'.
