I cannot use my droid 3 charger because im in Europe (different socket).
The droid 3 charger says 5.1V / 850 mA
Can I use my samsung charger 5.0V / 700 mA?
Thanks
You can use any microusb charger, if the current is lower the charging process is accordingly lower.
Currently I'm using a Palm Pre charger which can supply roughly 1A and charges the extended battery in about 2h
I know that the mA can be different, but I always thought that voltage needed to be the same? It doesn't matter that it's 5.0 rather than 5.1?

It's usb, the voltage is 5V in any device .1 V means basically nothing

Actually that .1 is the basis of all "rapid" chargers. It definitely makes a big difference. My I pad won't charge at all on 5, but it will accept any 5.1, including my d3 charger.

0.1 is pretty negligible, that shouldn't matter to charging. The car charger I use is Motorola branded and specifies an output range of 4.75 to 5.25 volts due to the noisier electrical environment in a car. I've never had any issues with it.

Chargers that don't charge, are usually non standard ones (read the data + and data - pins aren't connected toghether.
In that condition some device charges, some slowly charges, some don't charges at all.
Depending in how strictly they follow the standard.
I'm curious to know why manufactures always tell you in the manual NOT to charge the device using another charger than the supplied one, but what's the point of having a microsub standard then? i'm hoping they mean cheap chargers, but i think our phones would be fine using chargers from big companies like htc, nokia, blackberry, i think my galaxy s ii would be fine using my motorola charger

Most of the time, I used the supplied charger (this is when I charge while sleeping, for example.) However, I have charged with other microUSB cables (i.e., my Kindle cable, a previously-owned Verizon car charger, and just a microUSB cable I found sitting in my collection of cables) and they have always charged fine for me.
I can't use any of my HTC chargers (Desire Z, Legend) or my car chargers. I also cannot use a USB cable extension, and the phone requires a USB driver to charge.
5 vs 5.1 is almost nothing the important thing is how much current mA you can supply 700 800 1000 2000
The ipad doesnt charge well with 1000mA or below but is happy with 2000mA
And an ipad charger charges my droid in less than an hour

Yes.. but is there a limit to mA or could I connect a 4000mA charger (theoretically) and charge it in 20min?

Assuming a constant voltage (our case) the charging current depends on the load .
So, if the charge can supply a limited amount of current (eg. 500mA) the load can't draw more than that, but if the current available is more than the one required by the load (eg. 5000 A), doesen't matter, the load itself cant draw more than the nominal one.
Maybe that limit is not 1A but 1.1 or so, but definitely not more than that.

Ye so the phone is pulling energy rather than the charger pushing it..?
If the limit would be 1.1 how would you explain the ipad charger charging in less than an hour?

Look the matter this way:
The charger pushes the current with a force (the voltage), and the phone allows the current to flow.
Look the matter as hydraulics: if you have a tap with a 5mm hole, and the water is at a definite pressure, there is no variation in the water flow changing the size of the pipe (assuming the pipe is decently sized).
What matters is the input pressure and the tap's hole.

I've never opened the american D3 charger so I've no clue on it's real performances.
BTW, in the real world, the Milesone 1 charger charges (roughly) at 900mA, the X2 one at 850mA, the Desire Z one at 1A.
Often the real performances of the chargers has little to do with the one written on the sticker...
I can charge my D3 with my LG micro usb cable, but I can't connect to my PC or macbook with it :-/
I use HTC 5V/1A,it is perfect
For cryin' out loud, I'm tired of watching my battery drain while plugged into the supplied USB charger. It's ridiculous. I've never owned a portable device that discharged under normal use when plugged into its supplied AC adapter. If I want to spend 15 hours a day playing Angry Birds, it should be possible when I have a power source which is virtually unlimited. Twice, I've started the day with a full battery, had the device plugged in to the supplied 2 amp charger all day, and had <10% left on the battery when I went to bed. (No, I don't actually play Angry Birds for more than a few minutes at a time but I do use the device a lot.)

I don't have that problem. You do know that your device will wait till it drops some percentage before it starts charging again. It won't keep it at 100% the whole time... Is meant to conserve your battery life

Let's pretend I've got just a little experience with portable devices. The standard is to float between 95 and 100% charge and just call it "charged" once it's bounced off 100% the first time.
Here's a test you can do that requires no time on your part. Set it up to play a long movie while it's plugged in. Look at the charge level after it's been going for a couple of hours. And you don't have to take my word for it. I'm hardly the only person complaining that the supplied charger is not capable of keeping up with the device's power requirements.
If you are seeing power drop during normal use while plugged in I'd talk to Google. You may have a defective unit. Mine doesn't do that and I regularly see 20+ hour days with normal use unplugged and usually with some video, browsing, games etc.
Take note off when you see the drop, how much you lose over a given amount off time and call Google and see if this is expected. I'm sure they will help. They have been very responsive when I've called.

I will watch like 1 hour of Streaming Vid's and loose like 4-5% while plugged in.
100% brightness causes my device to use more power then what's being supplied from the wall charger, and a few other people have confirmed similar incidents as well.
Max your brightness, and then go play a 3D game, while being plugged into the wall charger, and watch the percentage drop still
My tablet lasts a few days at least before needing a charge. I plug it in over night and it charges to full. I couldn't be more happier with it considering it is not self-sufficient.
Mine drops a few % per hour in use with the stock charger connected. Brightness at 50%, WiFi on, BT off. I'm not going to whine about it, but its the only thing that's not great with this tab.

Why do everyone seems to think that the POGO-charger would be able to charge the Nexus faster?
I've read on an Ipad forum that about 10-15 hours charging are normal (the Ipad 4 has a 42,5Wh battery), and their chargers give as much Watt as our Nexus chargers.
One thing is clear, you can't increase the voltage. That would kill your Nexus right away.
My Samsung charger I recieved with my Nexus 10 says 5V out and 2A.
5*2= 10W.
Isn't that the same rates that other tabs have, even if they got special chargers?
So, the only thing the POGO-charger could raise, is the amount of current.
Even if you had a 10A charger, if the Nexus cant use more than 2A, it wouldn't get anymore amps than 2.
If the kernel on the Nexus doesn't support any higher charger rates, then you cant change anything.
There is a reason why the manufacturers have set 5V as standard - to make it work together with USB.
Battery Specs: Samsung Li-Ion 3.75V 22.75Wh 9000 mah.
So, it's easy. If you had a 1W charger, it would take 22,75 hours to get a fully charged battery.
In theory, it should take 2,75 hours to fully charge the Nexus 10 battery, but we don't turn it off, we use it while charging, it uses background sync and I dont know what the efficiency rating is on the charger or the Nexus.
You know you could feel some heat on the back of the Nexus 10 after some usage?
That's some of the battery's energy that spoils into heat, meaning that there are power losses.
It's normal though, we don't have anything yet on earth that could convert 100% energy from one form to another.
You could compare it to a car, you need a cooler-system to remove the excessive heat from the engine.
Even if your Nexus is far more efficient.

Please do not speculate about how much current can go through the pogo connection. Speculation is worthless and helps nobody. The fact that the included charger only puts out 2 amps probably has to do with limitations of the USB connection. But I'm speculating. See how pointless that is? The fact that one connection is limited to 2 amps doesn't mean all power connections are limited to 2 amps.
And where did I say anything about increasing the voltage? I'm not an idiot and didn't suggest such a stupid thing.
As for temperature, that can easily be monitored during charging and the current can be reduced if it gets too high. You are aware that there is a temperature sensor for the battery, right?
None of which has a darn thing to do with my opinion that it's unacceptable to produce a device that uses more power than it can get from its AC adapter. If there really is no way to run the Nexus 10 at full tilt without supplementing the AC adapter with battery power, Samsung should have addressed that problem before going into production with this unit. This isn't a $150 entry level device. It's the Android flagship.

Please, you started speculating about a high-current POGO-charger that doesn't exist.
Sure, you didn't mention the voltage, but I ve seen comments about it before, so I just wanted to make it clear.
And I didn't say the temperature was a problem either, just that it lowers the efficiency of the charger and the device.
Samsung maybe didn't know there was a charging problem.
We've seen examples before that manufacturers don't test their products enough.
(ASUS Transformer with encased aluminum body, anyone?)
And I know, this is supposed to be a flagship, but what everyone forgets is that it's much cheaper than other brands.
I was looking forward to buy a ASUS TF700 with keyboard at almost twice the price as the Nexus 10 before I read about the Nexus.
Even if it doesn't justify the charging problem, you could try to adapt to the circumstances until there's a solution.
When I'm low on battery, I let the device charge and do something else for a change.

I have a nexus 10, nexus7, and a Tf700. I am noticing slightly faster charging on the n10 using the Tf700 ac adapter. The same is true when trying to charge my tf700. The stock samsung n10 ac adapter charges it slower than the asus transformer adapter. The same is true with my nexus 7 adapter. Ive used the n7 adapter to charge my tf700 and it was not as quick a charge. Meanwhile all 3 units are rated for 5v 2amp.

Could be possible the N10 charger isn't actually putting out 2A? Might need a multimeter or something to verify for sure though...
I am currently out of town so keep in mind I didn't have a chance to dig too deep but I've given the kernel a quick look through.
There is no such thing as the "high current pogo charger." The pogo pins accept 2A max and appears to be ~5V. The USB connector has the same limits.
I also took a look at the current at the battery to make sure the charger was being detected correctly. My 1A Samsung non-Nexus 10 charger seems to supply ~900ma to the battery which is as much as you should expect out of a 1A charger. My Nexus 10 charger supplies ~1600ma to the battery. This number seems slightly low but at least indicates the charger is detected correctly.
*If* the pogo charger does indeed charge faster, it will likely be because the pogo charger is able to supply some current that is asymptotically closer to 2A. In other words, it will not charger much faster than the USB charger.
On the other hand, the pogo charger will still be nice to have as it will allow simultaneous usage of USB OTG and charging.
Like I said before, I was unable to dig very deep because I'm out of town and browsing sysfs and kernel source on a tablet isn't the best experience. So, the info I found might not be 100% correct.

There are many indicators throughout the kernel but for brevity I'll post what I think is the most concise.
https://github.com/CyanogenMod/andr...ng/arch/arm/mach-exynos/board-manta-battery.c
Line 773-776
Sets the current to 500ma if USB is detected on the pogo or 2A if AC is detected.
Well if you're reading 1600ma using the standard ac adapter that comes with the N10 and possibly closer to 2000ma (say 1900ma) using the pogo, then that is 1/5 faster charging. In terms of time that is quite a saving.
Of course, that is all speculation
USB current limits
I thought I'd post this as information I found while doing a spot of light reading
The current specification of a USB 2.0 port can be a maximum of 1.8A. Within Constraints.
"Battery Charging Specification 1.1: Released in March 2007.
A usb charging port places a termination resistance between D+ and D- to allow the maximum 1.8A", meaning that at this current, there can be no data transmission.
This appears to be increased for USB 3.0 standard.
"Battery Charging Specification 1.2: Released in December 2010.
Several changes and increasing limits including allowing 1.5A on charging ports for unconfigured devices, allowing High Speed communication while having a current up to 1.5A and allowing a maximum current of 5A."
citations come from documents here:
http://www.usb.org/developers/devclass_docs
As POGO pins do not have to follow any specification the only limit is the current the board & charging circuit can handle.
Look at the specs on the wall plug in unit. It's not a charger it's a 5V power supply and the charger is inside the N10. However the charger is setup determines the charging rate. Like mentioned above, it may not matter if you "could" use a 10A at 5V power supply.

How long does it take to fully charge your Z1 from 0%?

But I was expecting more improvement from the promised 70% with quick charge 2.0. This is around ~40% improvement, or am I missing something?

I don't think Quick Charge 2.0 adapters are out till early 2014. Even if they are, the one that came with my Z1 doesn't support it. Only Quick Charge 1. You can tell because the output is listed on the adapter (mine is 1500 mA).
Quick Charge 1 works on .7 to 2.5 A. Quick Charge 2 is 4+ A. (Standard USB 2.0 port will provide 500 mA while USB 3.0 will provide 900 mA).
So my 1.5 Amp Z1 charger isn't even at the top end of Quick Charge 1. With that said, I haven't tested a full charge. But if plugged into a USB 2.0 port, it barely charges while phone is on (few percent an hour maybe).

what you said does really make sense because quick charge 1.0 promise ~40% faster charge which I reported in my first post (+1 for that). Now is there any way to check whether the Z1 support quick charge 2.0? I know the chip S800 does, but what about the battery software or other internals (I am not really expert in this area). if it does then when new adapters are released with output more than 1500mA we will get faster charge time. I have my nexus 7 charger which says 2000mA, would this make difference and would it hurt the Z1 battery if I used it?
One last thing, if the output is 3000mA does that mean half the charging time? or there are other things to take into account?

All Snapdragon 800 chips have the QC2.0 circuit so we're good. Just have to wait for chargers.
I'm not an electrical engineer (studied mechanical) so I can't comment on things like losses within the charging process and all that technical stuff. However you have the concept right and in general that should be true. 3A charging a phone should charge it twice as fast as 1.5A

I've just made one test from 6% to 100% it take more than 2 hours i don't know if it was with qcharge 2 i've used the dk31 with a old AC to usb.
Other charge are made from 30-40% to 100%.
Mine takes an average of 2/3 hours to charge from 5% to 100%, I do however only use 1 Amp charges which are old phone chargers. I think I shall get my Note 2 plug out which is a 2 Amp charger and see how that gets on, I totally forgot I had it and I kinda annoyed me with its hissing noise...Even though I found out later it's normal!

The iPhone 5 has a battery half the size of this... I personally take about 2 -3 hours to fully charge the phone using the Sony provided charger!
Started Charging at 1:06 am - Battery was fully discharged.
1:23am Put Phone on - Battery at 11%
2:31am Put screen on - Battery at 52%
3:06am : Put screen on - battery at 73%
4:19am Put screen on - battery at 99%
4:26am Put screen on - Battery fully Charged .
I think the problem with the provided charger where the output is only 1500mA. the SGS4 with sd600 (does not support quick charge 2.0) comes with charger with output 2000mA which I tried with my Z1 and slightly improved the charging time. what we discussed earlier about early 2014 release of the quick charge 2.0 compatible chargers is the solution, I found couple of sources that confirm this. so we hope that better chargers to be released soon with 3000mA + ouput which would reduce the charging to to less than half.
it took 1 hour 40 min to go from 20% to 100%, I'm using the charging dock that came with the phone.

Yes I use a charger from a HTC One M8 and the Mate S charges in about 2.5 hours
For the huawei fast charge, you just need a charger with min. 2A and an compatible cable. E.g. the standard huawei charger cable. I'm using an 24W dual USB charger from Anker and the standard huawei cable. Phone takes between 2h-3h to charge from 10%-100%

I had read something about Fast Charge, a new tech announced by Huawei last November: about 40% of extra juice with a very short 5 mins charge.
The novelty here: (supposedly) no harm done whatsoever to the battery's lifespan/capacity.
I guess i thought that Mate S could be using it already, but no such luck.
Well, to be honest i haven't measured a full cycle charge using the original charger.
If we could get from 10% to 100% for less than 2.5 hours that's not bad at all :good:
Thank you for the tips.

You're talking about the New ultra fast charge Technologie from huawei combined wirh a New type of Batterie they are developing.
Hi
I have the P9000 on the way and I am looking forward to it arriving. One question I have is what are my options for a fast charger? I am in the UK so require a three pin plug and don't want to have to use an EU to UK adapter. Am I able to use one of the many fast chargers on Amazon that say they work for Qualcomm's Quick Charge but do not mention PE+?
Thanks
i use the supplied cable with a three pin usb to UK wall adapter that we all use with older phones.
never timed it but it charges within an hour or so, its much faster than any other device i have on the old charge system.
no need to buy the 2 pin fast charge device their trying to flog on their site.

Thanks for this.
I just thought some sort of higher amp charger would be needed to power the quick charging, but I shall wait until I have the phone then see where I can go from there.

If I had known that, I probably wouldn't of bought the fast charger ..arrgghh oh well
Mind you it does charge very fast, full charge in around an hour cant be bad

Yeah I thought the same too. Good luck with phone, I think you'll be happy with it. For price its a bargain
DON'T buy the Elephone branded wireless pad though, mine is rubbish (for normal charging that is, as I know its not a fast charger) its connects / disconnects all the time. Yet my son has a cheap wireless pad he got of eBay and its rock solid, lesson learnt I guess
I live in the US and I just use an iPad 12v charger. Takes around 45-60 mins to fully charge from 10%.
I use the one that came with my Google Pixel C

Anything with enough amps works, i.e. any of the tablet chargers >2.1A.
I have a five port charging bay that delivers 2.4A and it charges my P9000 just as fast as my "Quick" charger. Now I'm annoyed i gave out the 20€ extra...

Yes, agreed, my phone charges quickly, whether using the fast or a standard charger!
I'm using a Lumsing 4-port charger (the "old" model without QC 2.0; 2.1A max per USB port) and it charges my phone really fast, I'd say about 60% in one hour. So I dismissed my plans about buying the official quick charger

what is the output amp rating on your charger?
I just bought an Aukey QC3.0 charger and it does like 80%/h
I bought a meizo PE+ charger and it does the job. Around a hour form 0 to 100%
Are these chargers that you use safe / fully compatible
I'm using tronsmart quick charged with volt IQ, is a very good option

Using the Google pixel C charger and it's very quick!

How quick?
Everyone saying that the 'output amp rating' on 5V only output chargers is the way to determine if you're fast-charging your Elephone P9000 is unfortunately incorrect. A phone with PE+ uses load modulation to signal to a compatible charger that it should adjust its output VOLTAGE. There's a datasheet available somewhere that describes the protocol, but basically one set of current pulses (can be observed on an oscilloscope) means turn up the voltage, another set means turn down the voltage.
I managed to observe this behaviour, and simulate a compatible charger with a bench supply. When I saw the current pulses indicating a 'please increase voltage' signal, I wound up the volts on the supply from 5 to 12 volts, and the phone would draw up to 1A at 12V. If I left the supply at 5V, I would only see a maximum draw of around 1.7-1.8 A.
All this means is that compatible chargers are running at up to 12 Watts, whereas "high output current" chargers which only put out 5 V will only charge the phone at 9 Watts. Also, this is not compatible with quallcomm's quick charging system, which actually uses the USB data lines to request the increase in voltage.
Also, in general, cables are important. Phones will monitor their input voltage, and if they see it drop below some threshold, will reduce their charge current to match. If your charger doesn't have the current capacity to shove out to your phone, then the supply voltage will droop there and the phone will reduce the load. Similarly, if there is too much voltage drop down the cable (V=IR, R is the cable resistance, I is the current draw, V is the voltage drop) then the charging current will also be automatically reduced.
Also, strangely, my elephone p9000 recently stopped doing the PE+ thing! Now, there are no current pulses, and it only draws at 5V. *confused
I totally agree with the explanation of robot-army.
The Pump Express + charging technique is more than a simple current flow grossing.
This subject have been analyzed on another phone using the first mediatek Pump Express design used in the Zopo Speed 7:
http://forum.xda-developers.com/speed-7-plus/general/mediatek-pump-express-plus-zopo-7-t3336430
In that thread, you'll find the document that explain clearly the signal pattern awaited by Pump Express chargers to give their full potential. Without this management, they're just normal chargers and could be used in any other phone or device using USB standard to be supplied.
@robot-army: your problem regarding Pump Express management is known and it seems that since update 20160608, the kernel doesn't include this function anymore...
I saw that you shared your issue in the official Elephone forum on the following thread:
http://bbs.elephone.hk/forum.php?mod=viewthread&tid=11411&extra=page=1&mobile=2
I don't know if the kernel source used by Deepflex will let him put back this option ON in his CM13 Rom as it's an important feature of this phone and it seems that the Elephone Software checking team is not very serious about this point...
The lack of control of an highly advertised feature is a remarkable flaw, and even the last 20160715 update available doesn't correct this important point!
Please Elephone team, have some respect with your customer. The P9000 has a very good hardware basis, but you're making people changing their opinion because the software basis is not handled properly.
