[A700] Who else is also experiencing faulty chargers? - Acer Iconia A700 and A510

My charger keeps breaking, to be specific the cable.
The cable is very, very poorly designed. It contains 1 wire which is covered by braided shielding. The wire is the positive and the braided shielding negative. At the point where the braided shielding comes together for connecting to the micro adapter the shielding keeps breaking. This means no charging. I have tried soldering couple times but the shielding and wires are so thin it´s just usable a couple of times, until it breaks again.
I tried to make a DIY cable, but i didn´t get it to work. Probably need to place a resistant over some pins, however on the acer micro usb i couldn´t found one on the board where the micro usb is soldered on. Acer didn´t follow the usb standard with this adapter, the wire inside the cable is white, normally this is data instead of positive.
So i´m waiting for the 2nd time for a new 50 euro charger.
Just curious if more people also experienced this problems.

Yeah, I'm on my third charger now. You can charge them through USB although the charging light doesn't show and it takes about two full days to charge from low to 100%.
I have heard, though that a USB 3.0 supplies enough power to charge the a700. Haven't tried it yet, though. It may be cheaper just buying yourself a USB 3.0 PCI card for your PC and charging to that way.

I had similar issues where I thought my charger was broken, but it was a thermal problem. It seems, that if the charger keeps plugged into the socket for example over night, it can get so hot that it triggers some thermal protection and switches of. To reset the termal protection, It's not enough to let it cool down (which it does on it's own after shutting down anyway), but I had to unplug it for a couple of minutes, then replug it again - charger working!
I never had an issue with the cable though...

[Q] Broken Micro USB Port

Okay so my usb port has been a bit annoying the past week - where i had to vigorously wiggle the cable to get it to charge or to sync (and even when it did decide to connect to the computer, it would chop out eventually)
But now it's no longer charging or being recognized by my comp
It's strange because the headphone adapter was working fine, and so was the usb host, but it just wont charge anymore - I effectively now have a dead TG01
Currently, i'll get the orange light, telling me it's charging, but when i try to power on, nothing happens...
So i'm thinking a new USB port which is where I need some help: I'm not sure on what part to get
But maybe This is the one? Comparing the images with the ones found on the net of the TG01 (Yep - I still haven't got mine open yet)
But yeah, just a heads up on whether you think it would work would be epic, or whether you think i should just try a different battery/charger/throw it away (Although i'm almost certain it's the port, as it was working intermitently before - it's now gone altogether)
are u using only usb to charging or an wall charger?

Wall charger, but i tried USB, and still no luck
It just wont charge at all, regardless of the orange light when plugged in now that it's off (though i wouldn't get it when the phone did still have charge left and was therefore still switched on...)
BUMP: Any ideas you clever people? Just some guidance would be nice...
I'm still without my beloved TG01, I'm having to use a **** old Samsung G600
I do have some problems of my own with my USB cable. I believe the problems are due to the cable, though. The wall charger works fine. The USB cable that I use, has to stay somehow "forced"... imagine having the cell laying face up on a desk. The USB cable gets out and is forced by a small pen that stays right near the cellphone, to have a 30% slope upwards, so pushing a bit the cable onto the upper part of the USB port. I do know that you are telling us a different issue, however, maybe this way you could check whether it's just a broken connection and not a completely dead port.
No, this sounds like the exact issue i had...
It was like this with the Charger and USB - where i had to force it to be recognised or charged, and it would still cut out after a while - and wiggling it or knocking it wouldn't actually affect it, it would be of it's own accordance...
But it was strange because the headphone adapter worked fine...
Nothing happens at all now though
Are you try: Settings- Connections- USB to PC- unmark Enable advanced network functionality
I can't turn the phone on because it wont charge, so it's not that
Battery may be defective. Try with any 5V charger, connect directly to battery pin in 10 min
Hi
It vaguely remembers me of something I read on the forum about different micro usb (explaining my different cables do not connect just the same, some easy, some bit forced); I think there also was a drawing. (but I don't have time to search for the exact thread; it was not the "solving usb port mistery one))
Maybe your earphone adaptator don't have exactly the same as your charger? And if it is not battery trouble, find a charger with the "very right" micro usb plug?
Thank you both so much for your response:
I understand why you say it could be the battery problem with the charger - but it doesn't explain the intermittent connection with my computer when using the USB cable. Which is convincing myslef more and more that it's a port problem
One solution for now would be to buy one of these cheap external battery chargers from eBay, but it would mean i still wouldn't be able to use sync using the USB cable and i'm a bit conscious on whether the charger is safe and wont fry my battery
Which is why i'm leaning towards having a stab at reparing it myself
It'd solve the issue directly and it'd be a safer and more secure solution too... (the external charger would have to be ordered in from Hong Kong eBay)
I'm having what seem to be exactly the same problems. I have used 2 x usb based chargers on it - and neither work (whereas they had been working for the past 6 months). Got a mains charger last week - was working for a while - but as of right now, no longer works.
I'm not sure what else to do. I will try later to use the other adapter I have for connection to usb keyboard. The strange thing is - this will probably work but charging won't!
So....is it the micro usb port that's broken? (strange if it is but still works for data)
OR
could it be the battery?

Stupid thing stopped charging :(

So, I'm traveling (for a long period of time) with my TF. One day, it stopped charging.
I took apart the power brick and put it back together, I even tried to freeze it (on advice from some older "not charging" threads), nothing helps.
When I connect the TF to my laptop via USB - it recognizes the TF. When I connect my iPod to the power brick (with its own cable obviously) - it charges just fine. So what broke?!
I hate this, the local stores here don't sell the power brick separately and I don't even know if that's the source of the problem.
This sucks
Sounds like the power pin in the TF port has bent/broken or just has some detritus/dirt/foreign matter in it and is stopping it from charging properly. Have a look, but you might need to check the port with lots of light and a magnifying glass, so not easy while you're on the move.
If you are in the US Office Depot sells the charger and USB cable for $30.
strange thing is that sometime my transformer doesn't charge.
i have to reboot and it start to charge again.
Same happened here. Asus tech wanted me to wipe the device. After trying other options to get it to charge, I did but it didn't wipe... Go figure... But it booted up normally and now it has been charging.

Apparently charging has some history of issues on the TF101.
I just had mine act up on me, went around the house trying different wall sockets and checked that it worked fine via USB to PC. Ended up taking a can of dust-off to all the pins, then shoving the plug hard into the TF101 socket. Now it works.
Should have mentioned I have a dock as well, which doesn't charge either (so problem is probably with cable/brick)
I'm trying to get new ones (nowhere to be found here, but I'm trying to get one sent to me). I tried looking for dust/dirt and different wall sockets, no luck.
Weird thing - I left it plugged in to the wall overnight and it grew from 5% to 15%, so looks like some electricity is trickling.
I had the same problem with mine after I had it for 5 weeks, I just RMA'd it and everything is fine.
Im having the same exact problem. I left it charging over night by mistake the night before yesterday. I only let it charge 3 hours the most because I know the Transformers have known issues.
I tried to charge it this morning and nothing. I plug it into my PC. The PC recognized the Transformer but no charging. Turned it on and off, nothing.
Just put the power brick in the freezer, waiting to dry up to see if it works .
Although the tf charger and cable has a usb connector it is not usb compliant. the charger brick looks for a gnd signal on pin 7 of the usb connector ( normally a usb 3.0 data line) to determine it should supply 15V to the positive charge pin vs standard 5V. The slow charge you are seeing is from the 5V supply . check to see if pin7 is seeing the gnd signal. Are you using a usb 2.0 extension cable as it doesn't have have pin 7 conductor. be careful connecting your ipod as it could accidentaly see 15V vs the 5V it is designed for.

Port going bad?

Whenever I try to charge my phone it immediately switches from AC charging to usb charging, it is the charger or is the port on my phone actually going bad?
I had the same issue and was told to clean the phone port connection. Just put some compressed air to it or blow really hard in there and see if that fixes it. It worked for me.
thanks for the advice, I just tried my car charger and it works, so I'll give it a try later.
It could be the port but I would try different cables first.
I have a number of micro USB cables and over time they can get stepped on or scraped.
For example I was plugging my micro usb cables in to my phone and my touchpad and it would get a loose connection.
After going to work I tried my friend's cable and it got a nice snug connection and charged great.
So I would say try ordering a brand new cable of monoprice before you completely call the micro usb port bad.
I have noticed over time the tiny metal "teeth" that hold the charger in flatten out and you can't get a solid connection, I mean mine is so bad that I literally have to have the phone on the edge of the table with the cord falling to the floor to apply the right amount of pressure to get a charge

[Q] Nexus S (i9020a) Charge on an angle?

Hello
I am not sure how to properly explain this but hopefully someone understands what is going on.
My Nexus S (i9020a) doesn't charge properly. The original Micro USB cable that came with my phone frayed and no longer works so I went and picked up a third party one for $20. For some reason my phone will only either charge on an angle or upside down with this charge cable.
(It isn't the cable its self it works perfectly on everything else Micro USB wise)
I do find it weird that I originally thought it was the USB port on the phone that was dying so I cracked it open and there seemed to be no sign of destruction on the board so I put it back together. I then plugged it into my Nexus 7 Asus wall charger with the Asus cable and the phone charges properly no angles or upside down.
Any suggestions besides buying a $24 charger from Google?
Things I have tried:
1: Different wall chargers
(Nexus S wall charger + 3rd party M-USB):crying:
(Original Galaxy Tab 7.0 Wall charger + 3rd party M-USB):crying:
(Asus Nexus 7 wall charger + Asus M-USB):good:
2:Cracking the phone open to check the usb port on the board.
Phone: Nexus S i9020a
Carrier: Telus
Rooted: No
Version: 4.1.1
PS: Let me know if you need anymore information.
The thumbnail below is what I mean by Charge on an angle.
I doubt opening your phone will show you if the usb port is broken, unless you opened it previously. The most likely problem is that your USB port is worn out, dirty, etc and it's having trouble making contact with the cable ('charging at an angle' is usually caused by this). My recommendation is to try to clean it. First power off your phone, then try sticking something that can scrape the little metal pads in the usb port. Be careful that you don't bend or snap anything inside or outside the phone, so be very gentle.
Another possible reason, which is a problem I've run into myself, is that the charger you're using just doesn't work with the phone. My Nexus S doesn't charge when I connect it to a generic USB charger in my car, nor does it charge with most wall chargers and the original Wall charger that came with my phone was DOA. The only way for me to charge my phone is at my computer or with some wall chargers that, I guess, output more amps (I'm noob when it comes to electrical stuff! ). If it doesn't charge in one USB port, try connecting to another one and/or switching cables.
If it doesn't charge at your computer, then it's probably dirty.

Thanks for input.
I don't think the plug is worn out since it works perfectly with my Nexus 7 charger. I did look into the bottom of the phone and it does look a little dirty so that could be a small part of the issue but that doesn't explain why it it would work perfectly with one charger and not another. It does sound like it could be just the wall chargers I am using are not as good as the Nexus 7 charger (When I use the nexus 7 cable and charger the cable seems to fit alot better and it very firm when it is plugged in where when I plug in my 3rd party cable it is loose and feels like it is going to fall out. I might just buy the extra asus charge set from google since I know its a 100% work rate. was just hoping I wouldn't have had to spend that on just a wall chargers. >...<

Charging broke, DIY charger broke, possible tablet issue?

Hi,
My TF101 won't charge anymore. The original charger stopped working a while back, which is when I first switched to a 12v 1.5a charger with USB tip from Radioshack. ---Insert long story about using the charger last night to charge a drill battery and possibly shorting some wires in bad ways---. I just bought a brand new adapter from Radioshack. Plugged in my tablet, the battery charging icon pops up for a second then goes away and there are no other signs of charging. Same thing happens when I plug it into one of my computer's 12v rails (similar to this). I think it might be trickle charging, but I haven't yet left it alone for more than an hour or so. Same thing happened when I plugged it into a 19v laptop adapter (swapped out the barrel tip with my USB tip). The USB tip is a single unchanged variable in all of these tests, but when I was at Radioshack I quickly tested the new adapter with a new tip, and it did not work, so I don't think the USB tip is the problem, but maybe. A multimeter shows correct voltage from both adapters and computer. I can't seem to get any reading from the female USB tip plug, but I also don't know where the put the meter leads, when I put them both inside the plug I got some sparks so I stopped.
Could there be something wrong with the tablet itself?
Thanks,
Marc
Edit: Or how can I test the 30-pin connector that goes into the tablet with a multimeter?
