yea, your reading that title right lol

sounds crazy but i will have a project in the works that will be dual LED. ignoring the WHY, does anyone know how much power (voltage and wattage) a stereo 3.5 jack can take?

this project will be posted IF completed (kinda like the 50 other projects i never completed, but im serious about this one... just more serious than finishing cleaning up that xbox360 thats in parts on my kitchen table... for like 8 months.... ill get to that)

also look for my post on IR leds, need driver options lol

I don't u need 2 worry bout the large jack, i'd be more concerned in the size of the wire connected to it.

so you think they should handle like, i dunno 3.7 volts at like 1000ma? lol how about 3000ma? just kidding, dont need an XM-L for this

Should handle it most unwired plugs and jacks are fairly beefy inside though barrel jacks are usually used to carry dc power to prevent shorts when its jacked.

.

5

shorting shouldnt be a problem for the application. you would have to hold the switch AND unplug it at the same time

but thanks for the comments, that makes me even more sure of my switching choices lol

The plugs themselves?

Tens of amps at less than 30V.

The attached wires?

Depends.

The connections?

Probably around 2A if done well on a good day.

Do you need 3 wires? If not - mono plugs with 2 wires will probably cost less and be more reliable.

It depends on how fat a wire you can solder onto them. I'd guess 3-400W is doable but 20-30W is more achievable for those of us who aren't so good at soldering.

shoot, 20 watts is way more than i need

were talking 3-4 volts, maybe 1.5 amps (later considering a mono 3 amp as well, which will be a standard dc plug)

thanks don

i'd look at the plugs on a bike light with a multiple 18650 battery pack they use a regular center positive type plug...i'd agree ...look at wire ratings for amperage I'm guessing the wire will be were the resistance is not the jack .
