Pipo Max M1 charging issues maybe fried

Apologies if I don’t have the right forum lads,
I bought a Pipo Max M1 tablet about 3 months ago. I loved it , a very good tablet.
I bought a second one for my nephew as a Xmas present.
Before I gave it to him I charged it using my own charger a 5V, 2.5mA charger.
Then I took it to him in Greece.
Now when I went to Greece I never took my charger with me, I assume my nephews charger would do just fine.
When both tablets were discharged I used my newphews charger. This charger was a 12V, 1.5mA charger totally different from the one which came with my tablet.
When I used the 12V, 1.5mA the tablets showed both 100% charge in 2-3 minutes and then both discharged in less than 1 minute, clearly something wrong with that charger. Both tablets never charged again and where completely drained.
Now when I came back to the UK and used my charger (which was working from the start) , my tablet will not charge, it will not turn on and the tablet will get really hot when the jack plug is located when I hook it up to the power supply.
Is it possible the tablet is fried because of the wrong charger that came with the second tablet?
Could it be a matter of taking it to a technician and fixing it?
Any ideas guys?
Thanks in advance and looking forward to your reply

I have the same problem with you. They sent me the wrong charger (9V, 2.5A). The tablet was dead after 3 minutes. Now i'm waiting to receive the right charger.
Try to reset your tablet from the small hole in the back side. otherwise, you can try this http://www.slatedroid.com/topic/38865-dead-pipo/page__st__20__p__471674#entry471674

Panospc I have tried the reset button quite a few times but the batteries are completely drained!
Also I tried the method outlined in your link , although i had to cut the red cable and reconnect it but nothing happened.
My worry is that the tablet now overheats where the power supply plugs in.
Did your tablet overheat when plugged into the power supply without charging or turning on? Does it work now?
Thanks for your help by the way

I have only the 9V 2.5A charger right now, with this charger, both tablet and charger was cold all the time after 4 hours of charging. The tablet is not turning on. When I get the 5V, 2.5A charger I will inform you.
If you have a multimeter, try to measure the voltage of the battery, maybe the voltage is higher or lower than normal.

Yes I had the same issue when I was trying to get different adapters to work with the tablet.
I have ordered two seperate adapters from ebay both at 5V,2000 mA which the seller described specifically for the M1. I will post them to Greece and hopefully they will work.
Regarding my tablet as I am no expert, is it possible you think my tablet was fried?Can it come back to life?
A highest voltage adapter than 5V (the 12 V that I used) , do you think it burned the unit?
Thanks again ( PS: I think you are Greek?)

PS: I just got feedback from a technician and he said the unit is dead. I am starting to give up hope! shame!

maybe this suggestion will be work but i am not for sure.
i will take no reponsibilities of damages!
1. try to change battery.
2. unsoldered the battery from tablet and try to to relive with the correct charger ( maybe cut the cable of charger and connect the right pins to relive the battery)
3. connect tablet with the correct charger without battery to see if your table still lives.
good luck

Thanks for the advise mate
1. try to change battery.
no idea where to get a compatible replacement , if you can advise thats great
2. unsoldered the battery from tablet and try to to relive with the correct charger ( maybe cut the cable of charger and connect the right pins to relive the battery)
are you saying straight connection of the two battery cables to the power supply? will this not damage the battery even further? my charger is a 5V and the battery on top it says 3.7 V?
3. connect tablet with the correct charger without battery to see if your table still lives.
tried it no luck!

I got a 5V, 2A charger from ebay and my tablet works fine now.
I guess that the tablet has a circuit before the battery that prevents charging if the voltage is higher than 5v. So I think that this circuit was fried from the 12V charger and the current doesn't reach the battery and other parts of the tablet. You have to find a way to connect the tablet to an external charged battery with the same voltage to see if the tablet is alive, I think most mobile phones have a 3.7V battery also.

panos good to know your unit is working fine!
there are three cables when I open the tablet
1 red
1 black
1 grey
what's this grey cable doing? According to your advise, should I connect the red and black cables to an external 3.7V battery?
I read in a couple of forums that I can jump start the battery...how is this possible? any instructions/procedure?

Yes, Make sure you connect it with the correct polarity, red wire is positive and black wire is negative.

Thank you Panos
I will give it a try and will let you know!and fingers crossed!
Ps: if you hear in the news about a house exploding in newcastle that would be me messing up the battery connection!!

Hi guys I've got the same problem. I got my PIPO m1, but it didn't switch on with or without charger. I disassembled device and charched battery straight. So, after 8 hours of charching it has just 3.25 volt. And if I connect charger to the unit, voltage on its motherboard is 0.5 volt (battery is desoldered at this moment). It can't be the problem of charger, cause I used several ones (5V, 2.5A).
And! The main point! Stock charger was from PIPO m2 so it has 9V Unfortunately, I noticed it after my first charching tryings.
For now I've got a brick. Have you got any ideas what i can do to reanimate it?? ( Thanks!

SpookyXDA I will follow panos advise today and try to connect the tablet straight to an external 3.7v battery.
Also I will try and find a 3.7v charger and connect the battery straight to that charger and see how it goes!
I have the feeling the circuit board , like panos said above, was fried at a point due to the 12V (in my case and I think the same for you since you used a 9V). If anyone is here has good imagination and creativity on how to overcome and bypass the fried portion on the circuit that would be great!
i can upload a couple of photos if that helps!

I will wait for your results!

Iam afraid none of the things i tried works...i need to find replacement parts if this is going to work..i think a small section of the circuit board if fried.
When the rablet is plugged into the power supply it gets very warm which means electeicity goes through but i doesnt reach the battery
Any idea where to get replacement parts guys??

Have not had this problem myself. Try another USB charger? Just about anything that's 500mA will work (albeit not nearly as fast as the 2.0 amp charger that came with your phone).
I suspect your charger.

Good to hear it was a simple solution. You might check with the place you purchased it from to see if they will provide a new cable. I guess we can just be glad you didn't find out about the cable during the middle of an Odin flash...

No kidding. That would hurt a little

I am now having this problem after my phone got wet. No AC or DC chargers will work but the phone will always charge from a computer or even the USB interface of a car.
Even if I can get an AC or DC charger to be recognized, the phone will show as charging but the battery will continue to decline.
It is making no sense to me though I assume getting the phone wet partially fried something.

Yeah the voltage is increased to charge you battery when on AC power, at the kernel level. USB voltage is lower. So i'd say surely fried, and will no doubt stop working sooner or later.
I know that on my s2 I had an issue where it would say its charging and when I woke up in the morning no charge at all. The pin/row of pins or bar if you will would bend down and not make good contact. I used a tooth pick to pry up on it every time it did that.

Thanks. I didn't realize that the charging port was removable on the S4 so I swapped that out and all is fine now. :good:

Ummm... No its not the voltage. It is the ID pin. The voltage stays the same. The only actual difference is the milliamp mAH output of the charger. A normal USB plug has 500mA our charger has 2000. How the phone tells the difference? The 2 data pins inside he charger are shorted together. The voltage always stays the same.

Galaxy s4 not charging but does get power from usb

Ok first of all this is freaking terrible, I was using a cheap charger instead of my expensive charger and I had my hotspot on and the charger couldnt handle it so the phone just turned off, now it doesn't charge with any cable but it does indicate that is charging but its not, its draining. Yes I took the battery and swapped it with another s4 but the battery still works. I was litterally hustling but now I have to spend money to fix this. What is going on?

Try replacing the battery or charger check if it works.. And battery does drain while charging if u continue using the phone.. Keep the phone idle with data/hotspot off.. If its charging then ur phone is normal and you don't need to replace anything.. And yeah use a proper charger.. Don't try to charge it from laptop/pc USB.. It won't give proper results to come to a conclusion.
Hit thanks if I helped!

It's interesting how can people even do this ? we buy 500-600$ phone and then charge with a ****ty 3-4$ , from what i've heard it's so wrong to charge with a cheap charger as it can screw up the whole mainboard due to it's quality and low power output (lower than original charger)

Charging the phone thru a computer USB port is slower based on the output (500 mA) compared to the original charger that came with the phone (2.0 A)

Fast Charging problem!

Hello
Since a couple of days I noticed something weird with the included fast charger.
Sometimes when I plug it in the phones says 4h+ to be fully charged then I just unplug the USB cable and put it back in and it says 1h10min to be fully charged
Sometimes i even have to unplug it 2 times to get the fastest charge speed..
Is this normal or am I doing something wrong??
I'm rooted with arter97 kernel

It happen to me too, and im on stock. I do the same thing you do in order to get the fast charging.... is not the end of the world but is a little annoying.

Try using a different cable. I read somewhere that there was some issue with the included fast charger which turned out to be a bad cable.

I haven't noticed this as an issue yet however I never use the included USB Cable (could hurt resale value if accessories are beaten up)
Picked up a pile of very nice and thin Red USB Micro cables from eBay a few years back, they have lasted a few phones and still look brand new, cost maybe a couple of quid if that.

Okay I'll try changing out the cable, will see if it makes any difference

Get a new Micro USB cable from Amazon. They retail at around 5-6 bux and they are mostly 20AWG cables which should be much better than an old cable utilizing the Rapid Charging.

I would say thicker the better for charging. So, I would say smaller the better if you're going for a non OEM cable for charging . There are other factors too. Read this for more info.

Are you sure the problem is cable not adapter?

Anyone found an external battery charger that works?

I have a couple of spare batteries for my V20, but can't find an external battery charger that works. I've bought a couple that claim to be able to charge V20 batteries, but neither of them do.
Does anyone know of the charger that can be purchased in the UK which actually works?

The first one looks like one that I already have (and doesn't work). I haven't come across the 2nd one.
So have you tried them, or are you still waiting for them to be delivered?

Like I say i have them both, they both work fine. The second one charges faster than the first but I like the small form factor of the first one linked, it's very good for travel.

I'm using the LG OEM external charger in the US. It works great. It was sold only as a package including a new battery. I would be surprised if LG didn't make a version for the UK market. If they do, I would recommend it.

Hmmm....odd that the first one doesn't work for me. There is a voltage from the pins on the charger but the neither of my batteries charges when I insert them (and I have even left them overnight).
I've ordered the 2nd one to see if it's any better.
LG did have the BCK-5200 charging kit for the V20, but it seems to be discontinued. It's certainly unavailable in the UK.

So I received this charger this morning, and left a battery charging in it for 3 hours. The LED on the charger changed from blue to pink, but the battery didn't charge at all. I checked the pins with a multitester and the charger was delivering current, but the battery charge wasn't increasing.
Any ideas??

Yes I also have that charger - it doesn't charge any of the batteries that I've tried with it (only 3 of my 4 batteries will physically fit into it, and none of them will charge).
I really can't work this out - how come these chargers work for others but not for me? Surely all 4 of my batteries can't be faulty, particularly when all 4 charge perfectly well when they are in the phone.
