      Also a good idea. Why pay for electric or battery operated tools when you can just add a simple adapter to regular ones

    Why do this when you can just put your phone in the microwave and charge your battery by electromagnetic induction? I’ve charged my last 67 phones this way and it’s never been a problem.

    Want to have a battery that lasts for infinity? Troll Science has got your back.

    V = I.R

    where V is the voltage(volt), I is current(amphere) and R is resistance (ohm)

    Battery lifespan is calculated with mAh (mili amphere hour), basically ampheres per hour.

    We have already increased voltage to the AC (220 V), but we can go further and decrease the resistance.

    Longer cable = higher resistance

    Shorter cable = lower resistance

    Place the battery directly into the AC without a cable

    No cable = no resistance

    Now, the previously mentioned equation turns into

    220 = I.0

    This results in I becoming infinite. Electricity companies will go bankrupt, AI companies will be jelly. Problem?

      Not exactly

      For once, yes, current can be infinite, but since were working with AC, there is a limit how many electrons the plate in the generator can store until its full

    That like saying that a shot to the head is a cure for cancer - technically true but the other effects of the “solution” are worse than the problem.

    If I made that cable, despite being a joke cable, I would still have connected the main to the voltage contact in the lightning cable

      Please don’t. That plug has no adapter, and it would fry your battery (possibly even make it explode).

      Phone chargers have adapters in them which do two things. They regulate the voltage, and they add resistance which lowers the current (amperage).

      Phone batteries and internal circuitry have precise requirements to function safely and properly. The user manuals might give you the required range, or you can remove the battery and look at it, and it should say somewhere on it.

      The charger adapter should also have its specs listed. The specs must match the requirements of the device and battery, or bad things can happen.

      Fortunately, things tend to be standardized, so most adapters will fall within the range for most devices. But specialized devices might have unique requirements and it’s best to use the adapter they came with. Usually these will have a different type of plug so you can’t mess it up, but if you’re switching out unofficial chargers with different devices then it’s always best to check if they’re compatible.

      The thing in the picture connects the charger cable directly into the outlet. This could blow up your phone or start an electrical fire. At a minimum it will fry your semiconductors.

      It’s possible to wire your own adapters, but you need to know the specific requirements and include the correct voltage regulator and resistors.

        I don’t think anything could happen - there’re only two leads coming in and like 200 going out. There’s no way enough leads are connected properly to even intentionally improperly apply 220v AC into the phone.

          Generally the power and ground leads are just two leads, and the rest are all data transfer leads and stuff like that. You can plug your phone into your computer and do stuff (even though iOS makes that harder than it should be), but the unmitigated 220v AC would blow up your battery at the very least

        I genuinely appreciate your concern and explanation. It was 100% a joke, friend. No worries. I understand electricity and electronics enough not to do such a dumb thing 😅
