Tutorial | How to Make your own 5v USB power supply CABLE (without soldering)

Hello Engineers! In this video, I show you how to make a 5V USB power supply cable. This is a solder-less method that uses splice connectors to join two wires together.

Thanks for making such a nice, quick video and not wasting our time :D

Just the vid I needed. Straightforward.

Thank You so much for this short, sweet and on point video.

[mrjon]

Bro nice and simple no BS I love it and appreciate it

[anapaola]

Well that was easier than expected. Thank you for lifting my fear

[Valcano]

Best and simple to understand. Thanks for video!!!

I have something similar and hoping you can help. I have a small solar panel with red/black wire. I want to add a USB micro B to the other end. Is there a USB Micro B with adapter to simply plug the red/black wires into or would I need to do some soldering?

Twisting the wires and Hot glue or Electrial/Insulation Tape works equally well (Even Gaffa/Silver Tape), For those not having splicers laying about or just dont have the possibility to purchase them this instant but need to get a cable working.

Question: I have an end-table with a 120V socket and two USB sockets for charging. The plug end (at the wall) was wired backwards, so when I plug an outlet tester into the plug in the back of the table, it reports "Hot/Neutral switched". I can mechanically switch the tabs at the table end, but while that will fix the 120V plug, it'll leave the USB outlets soldered to the wrong wires.

My question is: do USB ports care? Will the circuitry fix whatever current problems the reversed circuit will cause, or will it fry anything that we try to plug in to charge there?

I'm asking because the solder is being very very stubborn, and my attempts at unsoldering the wire connections have only resulted in starting to melt the plastic housing the metal tabs live in.

you spared me 9£ + delivery for lot of 2 cables from china where I have dozens of unused USB cables here.

is USB from lighting the same amps as regular USB?

Do we need to join data wires ( white and green) ? Or leave them disconnected?

I’m trying to make a little retro gaming system with raspberry pi. I didn’t want to run power through wall. Just wanted to get juice from USB from tv port to hide all the wires. Do you recommend this strategy or am I going to fry my tv and/or raspberry?

[thisathdesilva]

my usb wire has only the green and white cables. what can i do now?

[kayb.]

Omygod this is the answer to my problem HAHAHAHAHA thank you so much!

I have a ir torch which runs off 2xcr123 but they dont last long is it possible to bypass the batteries and plug in to a power bank

My dash cam mini usb wire has only two colours. Black and white.
When I spliced Black with Black and White with Red to another data USB cable to get a power extension, it only gives a flickering screen. (Did not test it for volt. USB data has green, red, grey and white)
What is the case when power USB wire has only Black and White wire as explained above? Thanks in advance.

Can you merge the positive with the nearest data pin and merge the ground with it's nearest data pin to make thicker lower gauge wiring?

what will happen if I put 1 rechargeable ?

hello, can i use this technique with multi role power supply(input ac 100v-240 volts, 30 w, max 3A) this is for pca9685 controlling servos, cause usually the power supply only have one straight connector (which i think should be two red and black)there are other options too but i am still understanding every of them =__=; anyways thank you.
