    Trying to reconfigure this jump start/peripheral connector cable thing

    Hey so I gather at least this whole arrangement is "in series" right? Tell me if you don't know what you're looking at but I'm assuming you guys understand this stuff way more than me. So I wanna remove the jump starter part to this thing, and keep the SAE connector part. And I'm thinking I...

    Are these helmet headsets salvageable?

    These both died after charging them. I might have used a different charging cable that caused this to happen. Idk. Maybe they just suck. They're over a year old and I didn't use them that much during the time. They were stored in my garage the last 7 months or so though so maybe there's more...

    Looking for a suitable universal charger for a variety of electronics

    So suppose I get a 7v/3a spec on some little thing that needs a lot of current(what are they and why?), but my universal charger gives only 1.5a? Will that just result in the device unable to do something if anything but harm nothing? I'm now considering getting two, a 3-12v/3-5a one and a...

    The fastest way to learn is to break down misconceptions. Makes me wonder how many other misconceptions I'm running around this life with.

    Looking for a suitable universal charger for a variety of electronics

    On these adjustable universal adapters, you can only adjust the voltage, so how I'm wondering how the amperage is also adjusted. Is it increased with the voltage I presume? If so, how does that work overall with all the wacky v/a combinations you find with different devices i.e. 12v/1a vs 7v/3a etc?

    Looking for a suitable universal charger for a variety of electronics

    okay, I've decided I want an adapter with reverse polarity, that uses the standard barrel fitting. Seen some nice universal adapters but have their proprietary fittings.

    Anyone familiar with this USB charging cable?

    so yeah, that port is for charging out to other devices, and while I'm here, it's got a standard power port for a standard circular plug specifying 12v/1.5a. Am I right to assume neither of those numbers should be exceeded by any cable I put in there? If I can exceed, by how much. And is...

    Anyone familiar with this USB charging cable?

    USB charging port https://imgur.com/a/GZ506gG I think it's the opposite of what I thought it was. "USB charging" means it will charge your USB device. Not the other way around. It already has power cable.

    Anyone familiar with this USB charging cable?

    I thought it would just be another male USB plug so in order a male to male but they're all data transfer only. Might this type of charging cable go to a micro USB male plug that goes into like a power bank or would this just be a proprietary plug I'll only find the original to work?

    Laptop power cord compatibility

    My original laptop power adapter is 19V 3.95A and this $1 thrift store cord is 14v 3.21A. Could this suffice at all?

    Looking for a suitable universal charger for a variety of electronics

    Ah, I get ya. See my post above. "universal CHARGER" vs "universal POWER SUPPLY" two different things. Quick question: are there universal power cord workout transformers for straight 120v like sound boom boxes and printers with different tips? Something like that could come in handy too. I...

    Looking for a suitable universal charger for a variety of electronics

    Thanks, hmm... Maybe I should ask you guys what to get as I don't understand enough of the how these things work. I don't think I'm "charging batteries" as the audioguru said, for the most part. I guess with laptops you're doing that with your power cord or directly powering the laptop right...

    Having trouble getting power to heated motorcycle grips

    Yes, I tried to show in the dark video how I did verify I got power to the end of the cable that I want to connect to the grips, and the grips received power. Maybe it's off a couple volts? Could it be a matter of a weak cable? I just did I quick visual check to see that the dual moved at least...

    Having trouble getting power to heated motorcycle grips

    The grips are connected /spliced to a spare pair of these cables, so the grips connectors currently, as I've modified them have these sae connectors. And I can get power to them, through the quick connectors, but ONLY with alligator clips(to battery). But if I connect the connector to another...
