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
So I was gearing up to charge my N7 for the first time so I decide to leave it plugged in over night.
I wake up and I find that the screen is on and "Charging 41%" is flashing on the screen.
Anyone experience this yet?

Are you able to turn it on and run the device?
Play with it a while and see if things improve or get worse.
Were you using the OEM charger AND cable? The $1 chinese cable I used with the OEM charger had mine charging to 100% in 16 hours +
Make sure you are using the OEM Charger & Cable.
Also make sure you use the mains and not a USB port, I tried using a USB port on my mains and charging was like 1% per 30 mins, plugged it directly via the AC adapter in and started going up 1% per min.
I am using the charger that came with my Nexus One at the moment. It seems to work fine with all my other phones, does the N7 need more power or something?

It's not irrelevant. It means the 2A charger can source up to 2 amps if needed (which obviously it does need).
A tablet has a lot bigger battery and draws more current then a phone, which is why it has a bigger charger. If the charger can't source enough current to overcome the rate that the device uses power, then it won't charge or will take forever.

The stock 2A charger does it in about 3 hours and change from full drain power down to full charge.
Both of you are right, not the irrelevant part mind you but the part that it is enough and it may not be.
It all depends on what the tablet is doing at charging time. If it is off and the leakage current is low (as it should be) then most any 5v transformer will do. It will just take longer to charge.
HOWEVER if the transformer is not able to feed the N7 with more current than it needs to operate, on or off, sorry it won't work, no charging for you.
Now shake hands and go play outside.

No problem. I didn't mean to get snippy either, but I'm having a sh*tty day. ..To get back on topic, being an amateur radio operator, I have to have a little knowledge on electronic theory. My original response wasn't really to debate whether 1A is actually enough to charge an N7. My post to the OP was pointing out that he is in fact using a charger rated at half the amps of the rated charged of the N7, for whatever the reason it isn't working, and it also seems instead of trying the correct charger, he came directly in here.

The transformer is a source. It doesn't feed or force, it gives what is demanded by what it connected to it, as long as it's not over what it can handle (2A max rating) - in which case the coils of the transformer will get hot, possibly melting off the clear enamel insulation of the coils until you get a short and sparks flying out of your outlet, and pop a surge protector (hopefully)
edit: well unless it has some over_current protection built into it, or a fuse, in which case it would just die and not charge anymore :laugh:
edit2: But as just lou said, try the correct charger.
Another problem from using too low of a current transformer is you could put too much stress on it, and then it's voltage regulation circuits don't keep a nice clean steady voltage, and instead you could get spikes or noise, and that could lock up your device too. Of course this is just all possibilities, but to rule out variables it's just easier to use the correct charger
If the Nexus tablet requires 2 amps, then it will pull upto 2 amps. If it's doing this from a 1 amp supply, then the 1 amp power supply will overheat and possibly break. Amps can be larger than needed, but make sure voltage is correct.

I'm not sure of the voltage of the I9305 but the more volts = faster charging but hotter and hotter means a shorter life for the battery but it should be fine, I would trade it for faster charging. For amps, I have no clue and please correct me if I'm wrong anybody.

I'm pretty sure that you are saying the opposite way.
You can use more Amp but not more voltage.
More Amp - charges quickly.
More voltage - could blow your device.

AW: [Q] Charge with 5V/2A..?
In principle, the battery would load faster at higher charging current when the battery is capable of fast charging. If not, could reduce the battery life. I believe according to the charging control of Samsung, a current limiter is installed that can always draw only 1 amp. So it brings no benefit to using the charger of the tab. It may also be that the charging control of the current is limited so that is not loaded. The phone should not be harmed.

Should be fine for short term use.I've used half amp one amp and one and half amp car chargers wouldn't go any more than two amps no need to..may degrade battery a little so what there cheap enough to replace lol..easy peasy.. I live in tents an caravans 24/7 use leisure battery's not problem with amps just volts..bless solar panels..
The phone take what Amp it needs.. No more than its made for. 2A is only what the maximum out is for the charger.
You could make a charger with 50A, the phone still dont take more.
The volt is the value that need to be fixed though.
All phones charged via a usb needs 5V, no more, no less.(Usb =5V allways) Most batterys now days is something like 3.7V. Correct me if Im wrong.
Any way, you need a couple more volts in the charger than the battery to charge it.
Answere=Yes.. go ahead and charge.

I have had an HTC HD2 and used it's charger to charge my SGSII and now my SGSIII.
The time taken to charge with that is about the same as the SGSIII charger.
The charging circuits on the phone are smart enough to know that you are charging from a mains' adapter instead of an USB output from a computer and thus adapts the current draw from the system.
I previously did tests on the HD2 regardsing charging times and even with bigger supplies that the 1A one from HTC, it did not charge any quicker.

That charging circuit is made to cooperate with the battery and the rest of the phone.
So only difference you will notice is slower charge time if you are using a to weak charger that cant deliver the right amp.
As mentioned earlier you could use a 50A charger with out any faster charging time. Amps is allmoust of no interest if its not to weak.
Look at electricity as water. Amp is like how many liters of water a sertain pipe could deliver. Volts is more like how strong the flow is. To mouch pressure will destroy the flower. But with Amps you could pretend that the flower demands a certain amount of water and it will not suck more just becaus it could get more.

I am talking about all chargers in general. OEM chargers are better than the belkins, tankers and whatever. I read a couple very good articles about how good or bad chargers are. The ones that come with our electronics are usually the best. USB cables vary, sometimes even within the same models. The Samsung and apple chargers are really the best value when you consider longevity, heat, reliability and some other factors I am not qualified to explain.

Yes perfectly safe.
Amps (current) are drawn/pulled, not pushed. More amps in a charger just means your phone can draw more without burning out the charger. It does not mean that the charger pumps out more than your phone can handle.
Volts are different. Too much or too liitle volts are harmful but all usb chargers are the same 5v so don't worry about that.
Lastly, unfortunately the different manufacturers have created different special schemes to trigger or allow devices to exceed 0.5 amps (to prevent a high draw device from trying to pull 2.0 amps out of a 0.5 amp usb port and burning out a usb port or possible even all usb ports on your expensive laptop!)
So, merely having a charger that says 2.1A on the side isn't enough by itself. You will still need to try differnt cables and try different models of chargers and even different kernels if you are rooted, or refer to reviews where the reviewer covered this explicitly instead of just saying "It worked great" which is a meaningless waste of everyone's time.
For instance there was another thread about chargers where they found that on a 2 port model that has one port labelled Apple and another labelled Android or just unlabelled, they found that they actually behaved different. The Apple port was 2.1A and the Android port was only 1.0 or 1.5A, yet a GN2 charged faster on the Android port. Because the GN2 didn't recognize the Apple port as being capable of high current, at least not with a standard cable, and so the GN2 was only pulling 500 or 700 ma, while on the Android port it pulled 1.0 or 1.5A.
So you really need reviews and testing that takes all this into account and specifies actual charging times and that make and model of the usb cable used etc. Or just buy the official stuff from Samsung which is all garanteed to match and work as expected without having to know all that unsuspected stuff.

I have quite a bit of cells and tablets, who doesn't, but I also have quite a few rc cars and helis. All the battery's we are using are Li-on although I use a ton of lipo (lithium polymer) on my rcs. Ive built packs, soldered connections, I charge 6 batteries in parallel, etc. I have a 530 watt adjustable 18 Volt 30 Amp PSU connected to a 400 watt 18 volt 20 amp balance charger. Granted if your not in the rc world this would be overkill for sure just to charge your cell battery. Point is you can charge any, repeat any Li-on or lipo battery at 1 C. . 1C is the capacity of the battery. All of my lipo rc battery's can be charged at 5C. That means 5 times the capacity of the battery. In our case the note 2 battery is 3100 mah or 3.1A for short hand notation. So if you have a big enough charger like I do, you can safely charge it at 3.1A in an hour. Some of my bigger packs are 6S 30C 10A packs. That is 22.2 volts 30C discharge rate and 10Amp or 10000 mah capacity and 5C charge rate. If your not familiar with the above jargon no matter, the OEM Samsung charger with the OEM usb cable that comes with it puts out 2.1 or 2100mah per hour or 2.1A . Our stock OEM batteries are 3100 mah or 3.1 A. So they will fully charge in about 1 1/2. Ive timed it several times and that is pretty accurate. This is with the phone being off not on while charging. It will take a little longer with the phone on while charging, about 2 hours. Hope this helps.

This is with the phone being off not on while charging. It will take a little longer with the phone on while charging, about 2 hours. Hope this helps.

hi Joe , could you add some pics and diagrams . Thanks
Pics for what? Do you mean my lipo charger and PSU or the samsung oem charger? And diagrams for? Ill help, just not sure what exactly you want.
I've googled it and I'm getting very mixed opinions. Most say 2.1 of course is faster for charging. I am led to believe that because even the box to there car chargers say the same.
I would like to disagree but need help understanding why. Maybe I'm wrong and I have a faulty charger.
My charger has two ports. One is 1amp and the other is 2.1amp. My 1amp side seems to actually charge my phone faster than the 2.1amp side. Also with 2.1amp while in listening to music through Bluetooth using GPS and navigation all at the same time, it tells me my phone is dying faster than it's able to charge. With the 1amp side I'm able to hold a steady charge sometimes going up at least 2 percent during a 30 minute drive.
What's your opinions? This isn't the iPhone or Samsung threads so I'm sure we have some of the smartest guys/girls here on xda
Edit: sorry I'm a bit stoned atm so forgive me for my typos and I'll fix tomorrow.
.....don't judge. I live in Washington state. It's just as legal as buying a bottle of beer.

Ok sober now. So nobody knows why 1amp charges faster on this phone than a 2.1amp car charger? I've used several car chargers and it's the same issue.

It should be a no brainer that a 2 amp charger will charge your phone faster as opposed to a 1 amp simply because one has more output than the other. But I believe that because of the smaller battery the phones have, they need a smaller amp per second of charge. If not then it may destabilize your battery.
Thats just my two cents though. Dont quote me

i just drove 4 hours with a 2.1 amp , fast charge kernel and i can confirm your exact same findings. no idea why.

Be careful with those 2 A chargers. I have seen a lot of threads with fried Ones because of chargers lately

HTC put a limit on how fast the phone can charge. The chipset supports rapid charging but at what cost (of the battery)? So to be safe HTC disabled that feature of the chipset. So even if you plugged it into a 4 amp USB connector, you are not going charge any faster than say 1 amp. Don't know what the specifications are on the optimal amperage...

Fried what specifically? phone or battery?

Using a higher amp charger cannot damage the battery. The phone will only pull as many amps from the charger as it needs (probably 1.5 amps max).
Source: basic physics.

I am saying motherboard. I don't know about physics, but I know from reading the troubleshooting thread that many people have now expensive bricks because of those chargers

could you possibly link to those threads? I have the dual charger 1&2.1. My results are opposite of op my 1a doesn't charge phone but the 2.1 gains charge while driving even while watching movie! id like to read up if it may be problematic! thx
Htc one battery originally is charged by 5V and 1A charger; Can 5v. and 1.3 A damage the phone?
One thing that nobody here has mentioned is the possibility that your charger might have been wired wrong and the side that charges faster is actually the 2.1mah connection instead of 1mah.
With all of the chargers from everywhere in the world that we get them from and they are supplied from, anything can happen that We don't expect.
Maybe you might want to get it tested with an OHM Meter to verify which connector is the Higher and which is the Lower.

The only thing that is different (as far as the phone is concerned) is whether it sees an AC style charger or DC style. No matter what, the phone will only pull what the charging circuit "says" to pull.

For some chargers, sometimes the 2 Amp port appears to be using the Apple protocol for USB power, so that port will only provide 0.5 Amps to most other devices. And when the1 Amp port somewhat over delivers, and can source 2 Amps if nothing else is connected and 1.5 Amps if the 2 Amp port is sourcing 0.5 Amps for a non-Apple device. Thus some chargers can support one high power non-Apple device (in the 1 Amp port) and one lower power device (in the 2 Amp port). FYI I use this charger bought on Amazon---Avantek. Worked really well, versatile and low profile.
