Hmm thought the usb cable unplugged from the wall charger so it could be used on a computer. At any rate I have noticed that my Kindle charger works great on my Defy.

I used the charger of an HP Touchpad with 2000 mAh instead of the 800mAh of the Defy charger and would say it charges much faster. Unfortunatelly i "had to" sell the HP Touchpad with its charger and i am looking for another good USB-Charger. In the past i bought one from ebay for not much more than 1€ but it only has 500mAh i am thinking about this one "from HTC" with 1mAh
ebay.com/itm/170738630232[/url]
This one is listed with 2100mAh: ebay.com/itm/170767447174

I believe that you think on output current. That is mA, not mAh. And ofc that it chargers faster, just like you eat faster with bigger spoon

hello cickvoa,
you are right, it is mA, because milliampere per hour (mAh) is for battery's capacity and not for output currents. i hope everyone knows what i mean.
on the other hand i guess that the charging unit is also a factor the charging speed depends on. is it possible that a too high output current could damage the phone?
is anyone able to suggest a good charger with a current >= 1000 mA?
regards ladiko

It is not possible do damage charging unit, cause it will take current that needs. For example: USB on PCs is 5V/500mA (500mA is MAX current that source (USB) gives), and when you plug mouse it takes only 100mA. So, charger with 2A output is MAX, and defy takes less current

Any risk in using a different charger than the original samsung one to charge the sgs2?
I use a combination of blackberry charger at work, universal micro usb charger downstairs at home, universal car charger and official charger upstairs.
Any concerns with this?
I've been doing that for ages. I use the droid, SE x10 and iPhone chargers with no issue.
As always YMMV
I am using htc's charger which has a higher rating than samsung charger. No problem at all...

I use a Sony charger to charge my S2 , I have not even removed the Samsung one from the box , As long as you use a branded charger will be fine.
I've tried to use Nokia's 1200 mA charger, It did charge the phone but whenever i connected that charger the phone would slow down terribly. So, whatever you use, try to keep it around Samsung's charger's 700 mA.
Ive found that the standard charger is rubbish! I had my galaxy s 4 month and it broke, my wifes galaxy 3 did same and now i dont even bother with the one out the box, just use the usb cable and the adapter i got with my tab.

Absolutely right...my phone is about 1 month old..and the official samsung charger is already broken..not charging anymore..i guess there is an internal wire breakage at the flexible point of the charger becoz when i shake the wire at that point it starts charging intermittently..

Same here. I tried all sorts to get it to work with no joy. I now have 3 duff samsung chargers that are potentially a fire hazard if left plugged in! Tempted to email samsung and raise this concern.

At home I use a Lenmar AC-to-USB 1A charger I picked up at Fry's for around $10; in the car I use a 1A Cygnett 12V-to-USB charger, also from Fry's. Both charge the device at least as well as the OEM AC charger; the car charger appears to charge the SGS2 even when I'm running CoPilot Live.
I use the iGO charge anywhere.
It's a tad pricey, but since the GS2 battery life isn't great (my only complaint on the phone), the charger is great for it since it has an internal battery that charges up when you put it in an outlet so you can charge the phone without needing an outlet. Great for in school or walking around, just put it in my bag and press the button and it charges.
I'm using my BlackBerry charger with no issues, I just do it for convenience as the charging time is the same as the standard charger.

+1 .Just used the charger from a different brand and no bad feelings while using it
well, i just emailed samsung raising my concerns regarding the faulty chargers... see what they come back with....
Guys have you noticed any change in response when we plug in another charger?
I have been using the HTC charger, 200 mA (input), Output 5V --> 1A.
Whenever i connect my phone to charge and try to work on it, i see my screen lag terribly. Haven't tried it with the supplied charger though due to the low voltage that came with it.
I know i would be wrong, but wanted to check with the experts on this forum...

200ma is way low, less than half the 500 ma usb standard. Get a new charger. Most of the chargers you are going to see will be 500 ma I would go with double that.
Some (bad?) chargers will disable touchscreen
I have a couple of usb-chargers off ebay and they give some trouble.
When connected, the touchscreen will not work anymore.
This is mentioned in the manual btw.
Guess the SII is a little sensitive.
Yeah, ebay chargers are a crapshoot. Head to walmart or similar and read the power specs, get something that puts out 5v at 1A LPS. This will charge much faster than the often usb based standard 500 mA chargers and the battery will not be harmed at that charging level which is what many stock HTC chargers put out nowdays. Do not get anything less than 500mA, this is the usb standard and works but will be slower to charge. El Cheapo no name chargers on ebay and such may have the spec but may or may not actually put out the juice. You can usually tell this because the phone will have problems like the ones mentioned right here. The stock charger does not put out any special juice, juice is juice. If a charger puts out to spec the phone will work while charging.

Galaxy Note without original charger

Hello to everyone!
I have one simple question: do I risk something if I charge the Note with another charger than the original one?
I don-t know, but I think no.
I charged many time my note with htc charger and gs2 charger.

I almosr never use the original charger. I use the charger that came with the bluetooth headset and everything is fine
It doesn't matter what kind of charger you have. The only thing you must look at is the voltage of the source (5V DC) and it must be a micro usb plug

im using my old htc hd2 charger as the samsung one seems to have packed up and isnt charging properly
The easiest way to charge your Note is of course via a USB>Micro USB cord plugged into a laptop or PC (where you are guaranteed the voltage is correct), however if you are using a generic or knock off wall wart charger than provides a micro USB connector there is some small chance that it will not charge your Note.. look for the charging icon and if its not charging, toss the charger and get another.
There is no specific risk to the device, provided that it (the charger) has a micro-usb intended for charging generic devices..its just that some modern portable devices have a stricter requirement (tighter tolerance) for charging voltage and simply will not charge outside that voltage range.. my BB9930 does exactly this..

Since all micro/mini usb chargers have the same voltage, and vary only in the power output - the only problem you could face is slow charging, or no charging at all if the charger doesn't have enough juice. But it certainly won't harm the phone.
I'm using my old Nokia N900 charger without problems
I'm using an old HTC mains-to-USB and a Nokia microUSB cable...
My stock charger has a slight squeal, so I usually use the charger for my BB Curve 9300. Does totally fine.
My Note was purchased from expansys UK but shipped in from mainland Europe. As it was to be sold in the UK, expansys had to supply a UK adapter rather than an EU one ...I received an HTC adapter with my phone. At first, I was worried, but discovered that it works beautifully with my Note. Charges faster than generic Samsung chargers too! You should be fine using another standard charger

For the first 3 weeks I was using a blackberry (original) Bold II charger.
I noticed charge time was too long. And maybe even battery life was shorter.
Im not 100% sure about the second statement but the first is confirmed.
When I started using the Note charger it was faster. Not super fast compared to iPhone or iPad but faster than using the Bold charger.
I never use my samy charger..Im using my DHD charger..no problem at all..

Most modern USB chargers should be fine (I use my old iPhone charger for the Note, for example.) Watch the power output though - some tablet chargers are rated at 2A+ and that could overdrive your charging circuit and cause damage. If you make sure your charger is about 1A (and 5V, obviously) then you should be fine.

Well emuX said it all!
1A of output and 5V and you are fine!
Actually the charging current is limited by internal resistance of the battery, so the battery effectively "accepts" charge. Charging current is not "pushed" in by the charger...
obviously a charger from say a BB is likely to be current limited and so longer charging times would be expected, but an iPad charger will work fine.

I wouldnt worry too much, I charge my note with my iPhone charger purely because the USB port faces a different way so I can actually fit it on my plug extensions without loseing 2 sockets.
Pretty much anything with an output of 5Vdc and a minimum of 1A will do just fine.

Can I charge NExus 7 with a 5V 1A charger ?

Bought my Nexus in the US this summer, really enjoy this little beast.
I have a question regarding charging. The provided charger is a 5V- 2A charger but a US one. I have at home a HTC one X charger which delivers 5V - 1A. Can I use this charger ? What is the difference between 1A & 2A ?
Thx, Yves

I don't see how less amps would hurt it. It may not register a charge, or charge very slowly. I would wait for another opinion.
2A will charge faster than the 1A charger. That's the only difference.

OK, thank you
On the flip side, can I use my N7 charger to charge my mobile (SG2)?
My SG2 charger is set for 0.7A, while the N7 charger is set at 2A.
Mine charges with the USB cable i use to transfer files, which is about 500mA. Works but slow.
checking around the net, that's what it say.
the USB port have a maximum of 500mA i believe. And i did noticed it tend to charge more slowly. While the provided Asus charger with USB port on it, it have 2000mA (or 2A). So i guess the Nexus 7 is made to be able to support up to 2000mA, while it will charge more slowly when connected to a computer's USB port.
I took out my PSP and its charger recently, and this charger is also 5V, 2000mA, except it's a round tip made to fit the PSP charging port.
I do have another 2000mA charger, it also have a round tip, luckily it fit on my Ainol Elf II tablet. I got this charger/power supply when i bought my HDMI switcher, it work without it, so it was sitting there for all this time, unused.
i'm gonna try charging it with the provided Asus charger now.

Third party chargers for the N4

Ive noticed the stock wall charger delivered with the Nexus 4 is rated at 1.2A, 5.0V. My old phone had a micro usb charger at 0.8A, 5.0V. I imagine the N4 will charge on the lower rated charger, but would take longer. Isnt the standard usb rated at 0.5A? My desktop PC has a new Asus board that has the Charge+ 3X Faster Charging, which I would guess means the usb can pump out power at 1.5A. Looking around for a car charger and additional wall charger, I imagine the N4 would be fine with a higher and lower rated charger? Or should I stick with 1.2A or less? Ive seen car chargers at 1.0A, 2.1A, and 3.0A.
the n4 will only take the current that it needs. a higher Amps- rated charger won't hurt it.
i use a 2.5A portapow quad output charger, the extra power of which enables the charging of multiple devices simultaneously.
I bought this charger for s2 when I had it.. and sold the phone immediately. However I still have this charger. Now what I want to do is, keep one charger (stock) at home and the other (Nokia one...which is also Original) at my workplace. I want to know, is it compatible? As the manual say, u shouldn't use 3rd party chargers. So I want to know your expert opinions "before" start using it on N4.
Thank you
I use my old blackberry + LG car charger
^ You think this would go fine with my N4?
The Output/Input is all same.. only 160 mA is diffrent from the Stock charger. So I don't really know.

About AC adapter and its amperage

Hi all,
Ok, so I finally managed to order a 16Gb Nexus 4 and hopefully it will be with me in 1 week or so.
And I was wondering one thing regarding the AC adapter: I believe (pls correct me if I am wrong) that the original AC adapter’s output voltage is DC 5V, 1.2A.
I will need an extra AC adapter to keep it at work and I was planning to use one of those:
- The Sony Xperia P AC adapter will output 5V, 1,5A
- The Samsung Galaxy S AC adapter will output 5V, 0,7A
It is clear that neither of those 2 chargers will match exactly the specifications of the original Nexus charger (same voltage, but different amperage).
So, here goes the questions:
1) Is there any problem if I use a charger that will output the same voltage but with different amperage?... if not, which one would you use and why?.
2) how the amperage affect to the charging process?.
Thanks all in advance
PS: sorry for terrible English
You can use any charger up to 2 amps.

You must use a 5V AC USB Adapter and better no LESS than 1A
for Fast Charge.
AC Adapter I Use:
iPad AC Adapter 5V 2.1A at Work
PlayBook AC Adapter 5V 1.8A at Home 1
Original Nexus 4 AC 5V 1.2A at Home 2.
Our Nexus 4 will Draw around 0.8A when Batt lever at 0% - 80%,
then around 0.5A at 80%-95%, Final State 95%-100% will draw 0.2A roughly.
When 100%, Nexus 4 will use the AC power & the Current "A" show on phone
will like 2mA (0.002A) when idling.
** 1A = 1000mA
As previous poster said, do not go under 1.2amp.
I run the OEM charger in my bed room, a USB charger to my computer, and a 2.1amp charger in the car.

Why do you say not to go under 1.2A? Charging from a laptop is at .5A. I've been using a 1A charger since day one. Haven't experienced any issues with it.
Charging at a lower amperage shouldn't hurt anything, just charge slower. All you have to do is make sure it's a 5V charger. Amperage shouldn't matter but a lower amp charger will charge slower. As for a higher amp charger, the phone will only draw the amount of power it needs to charge so using 2A charger won't hurt anything either.
Also 2mA is 0.002A not 0.02 A

Since the charger doesn't actually regulate the charging itself (the phone does this) it doesn't matter how many amps it can supply, could be 100 amps, no worries. As long as it is 5V, the phone will draw as many amps as it needs.
Since the supplied charger is 1.2A rated, it's fair to assume that the phone will never actually try to draw any more than that, so there will be no benefit in going higher.
Going for a lower current charger will likely extend the charge time.
I use a 2.1 amp daily without any issues.

Wow guys!!... thanks all for your answers!!
So, if I understood correctly, the amperage will only affect to the charging time, meaning that by using the Xperia P AC adapter (1,5A) the battery will be charged faster that using the Galaxy S one (0,7A)... right?
Pls allow one last question: a few yeard ago, I think I read in some forums that a slower charging process could help to keep the batteries in the best conditions for a longer time... is this still true with modern batteries??
Again, THANKS all for your help!!

Yes, the .7A charger will take a little longer to charge you phone.
On the other answer, I think NO but I'm not as familiar with LiPo batteries. I would venture to say that .7A vs 1.2A (max the phone will draw but I think someone above mentioned it's even less than that when the battery is very low) is not going to make a bit of difference in your battery life.
One thing I do know about LiPo's is you do not trickle charge them. So while plugged in it will charge at the rates mentioned above until full and then it QUITS charging all together. Once the phone discharges the battery to a certain level, it will charge it back up again. Probably at 98-99%.
There may be one other thing to consider when selecting a third party charger. In the Nexus 7, the device looks for pins 2 & 3 (data) of the USB plug to be shorted in order for it to draw full current. If this pins are open (or have a load across them as is the case with iPhone/iPad chargers), the Nexus 7 will assume it is plugged into a computer and limit its draw to 500MA.
Not certain the Nexus 4 behaves the same way but would assume so.

setzer715, thanks for the answer... I think I will be using the Xperia P charger at work...

I want to make this case clear. According to my Charging log,
Here is some key point.
Nexus 4 Max Draw Rate at Fast Charge Mode is around 800-900mA,
even you use a Charger that rated at 1A (iPhone Tofu), 1.2A (Original),
1.8A (Playbook), 2.1A (iPad).
Fast Charge Mode must be with Charging Cable with 2&3 pin Shorted,
or the charger itself have the 2&3 pin already shorted.
Therefore, 1A is a Sweet spot for getting Charger & Charging Time for
Li-Po/Li-Ion/Ni-MH Batt charging.
If you use under 1A Charger, eg 700mA or 500mA, it will take much longer
to charge the batt but no harm as well. Just too slow only.
The stock charger that came with my phone sucks, I use one from my epic 4g touch (gs2)and it charges much better

Left a phone on a charger all night with a long (10ft) cable and it couldn't even charge the phone over night. I know a 10ft cable will slow things down but my gs2 plug has no problem charging my phone. Search around and you'll find a few fail stories about the stock LG charger.
