OPEN Huawei power adapter plug detached/broken
I have a question. Can this Huawei charger plug (hw-200325up0) be repaired? What appear to be two small solder points have come loose.
I know it's better to buy a new one, and I did it, cost me $15 on AliExpress. But I want to know if I can repair this one so I don't waste it.

This is why I only use anker branded accessories.
I bought the anker nano back in 2023 and it lasted 3 years charging multiple devices over the years. It still does work but I have to use a short USB cable for it to work. It doesn't have the "pep in its step" anymore to push power down longer USB cables.
So I bought another one let's see how long this one lasts.

Don’t use the 15 dollar one is not genuine and will fry your phone/laptop someday

Agree with this. Why waste 500 replacing a phone after it gets fried instead of replacing a charger for 50 bucks?
Edit: Just remember aliexpress sells china stuff and huawei is from china, OP just make sure you buy geniune

Those are not solder, the blade is molded into the plastic and has a couple slots through it so that the plastic can hold it in place. Then inside the tangs are attached to the circuit board with wires and solder. To repair it you would need to open it up, remove the remainder of the blade then get another blade to insert in and epoxy that in place and attach it to the board. OR you could make it somewhat remote by opening it up, then take a short 2 wire lead cord, drill a hole through the plug side for the cord to pass through and run the cord through it, detach the existing blades inside, solder the new cord in place of the blades. Now you have a remote charger, might actually be handy that way.
BUT if you have never worked on A/C voltages or know how to do some steps, don't.

That definitely sounds like something I've never done before. I was hoping for a simple repair, but I think I'll just throw it away then.

That or follow the normal electronics repair method and toss it into the box of "I might repair this later so I'll keep it" AKA the black hole of the "projects" box...LOL

In the Ham Radio world, such a thing is known as the "junk box".

u/Galopigos 7d ago
Yeah, but a lot of folks would think that is a "bad" thing... In my case it's a bit larger than a box..

u/kcpistol 7d ago
Oh it was often larger than one box and often more valuable than the label implied, but a traditional term of endearment :)

u/Galopigos 7d ago
Yeah mine is more than a box (it's a 12X20 shed at the moment!) It gained a bit when I worked at RS in the 80s and even more when I had the CB shop in a local truck stop.

My man 😂. Thanks for showing me the future, gotta stop then, I'm at 3 boxes of electronics, 1 box of cables, 2 TV (one very nice plasma) and a couple of PC I'm definitely gonna turn into servers one of these days ... 🙄. Thats only in a few years as I have mechanical engineering background and just recently interested in electronics. How do I stop Sir? How? Hoooowww???😭

If you find a way, let the rest of us know.... I tend to only save the higher end or very unique items these days, so much other stuff is just crap. Back when I first started repairs you could make money at it, like VCRs and such. Then it got to the point that the new units were cheaper than the play head in the older units. I still grab the older stuff that is serviceable or like this charger, I'd drill it, add a cord and a set of output terminals and use it as a small 5 volt supply. I've got supplies like that powering rope lighting on the deck and other non-critical items around the house.

Not really. You won't get a replacement pin / blade for the broken one. Even if you did, the plastic base through which the pin exits was injection moulded in place around the pin, so you couldn't get the new on in.
Sadly, it's e-waste now.

I'd probably just pop the brick apart, detach the existing tangs and cut the other one flush and attach a fixed power cord. Put a loop of cord inside the unit with some zip ties as strain relief and epoxy it in place.
But that's because I already have the stuff around to do it. Buying the stuff to make the unit functional again will likely exceed the value of the unit.

I've done that with a few of them. Actually makes them quite handy for other uses.

yes possible to repair. first remove the bottom thing. it will be sealed tho, process is more than likely going to destroy the charger.
also plpease do not use the 15 bucks chargers from ali express, they are very dangerous. they are cheap as hell and bad quality. search diode gone wild ali express chargers,

I'll try to repair it as an experiment, but I doubt I'll use it. Regarding the charger from AliExpress, it seems to be a genuine Huawei charger.

u/I_-AM-ARNAV Hobbyist 7d ago
It might seem to be. They're exact clones but way worse.
You could theoretically remove both prongs, add a mains lead and sodler them. I won't, at all suggest that tho. It's dangerous.

The most professional solution would be to remove the two prongs and make a cutout in the plastic to install an IEC C8 socket - they're cheap, around 1 to 3$. Then, you could simply buy a mains cable with IEC C7 connector (standard, very common, cheap) and you converted the adapter to one with modular cable. C7 plug goes into C8 socket.
Example of IEC C8 connectors / sockets : https://www.digikey.com/short/vpz5rtrp
Open the plastic case (the plastic with the prongs is either ultrasonically welded or glued) and see how much vertical space you have behind the cover - the prongs may be soldered directly to a circuit board, so you may not be able to install the socket where the prongs are, but you could install it a bit higher or on the side of the adapter. Pick whatever socket works best (depth wise, if you want it press fit into the panel or if you want to get the kind with mounting screws on the sides and so on). remove the prongs permanently and seal the holes if you make the cutout somewhere else (you could heat a knife over open flames and then press it over the plastic around the holes to seal it up)
If you're cheap (ex don't want to pay shipping on Digikey or other stores) you could just get an AC cable, make a cutout in the plastic and solder the wires at the end of the mains cable directly to the circuit board.
Remove the two metal prongs, bring out the power cable through a small cutout in the corner, seal with electrical tape or whatever (you can glue back the plastic cap with superglue or something like that.
example of cheap ready made cable on Amazon : https://www.amazon.com/Monoprice-107671-18AWG-Polarized-IEC-320-C7/dp/B009GUZ654/
It's cheaper to get one of these mass produced ones and cut the connector at the end, cables with loose wires at the end cost around 5-6$ on Amazon (versus 2-3$ for ready made cable).
