Yes. For that matter any charger with output of 1amp or less is fine. Just make sure out is a good quality charger- Samsung is just fine.

I have this rule when it comes to charging phones: If it fits, I charge.
Which is not completely safe, but hey, YOLO.

one of my family member is an excelent multi device reparator " every thing which works with electricity "
he told me that if the phone power is 5V 1A, then all chargers that are less than 1A will make the battery HOT
and all chargers that are more than 1A it's fine to use them because the phone will use only 1A so the charger will gives him only 1A
(i tries this on other devices)
i used my phone with a Sony Ericsson charger and it worked as if a ghost is using my phone (touchscreen is working randomly by itself) then i used a samsung charger and its good. But still i guess using the original charger from htc is the best. I have to buy one myself :/

The stock HTC charger is 1A. The stock USB charging voltage is 0.5A... My phone does not get all that hot with my stock charger or while charging through USB. And my car charger is 0.5A too, does not heat up the phone even while using GPS. The way it gets warm in all three charging scenarios is the same.
So- what I posted is from experience, that too with 2 HD2 phones that I have and use for close to 3 years. And yes, I have my multimeter and soldering rod handy too!

It won't be enough if you're the type that uses the phone while plugged in. IF on the other hand you don't use your phone while charging, it will be enough.
If you still have your original HD2 data cable, though, you can leave it plugged in your PC and it will charge up fine as though it were using the original wall charger. Which is what I do most of the time. I only use my wall charger for emergencies, or when I don't have a PC to plug into.

It will be fine. The phone/battery controls the charging current, NOT the charger. You could safely use a 2A charger, and it will still be fine - because it won't charge at 2A - that's just the maximum the charger is capable of.

While a charger rated at higher amp wont theoretically hurt the phone or the battery, I had a sour experience with my $1000 SE P900's charging circuit going for a toss after plugging it in to such a charger- this was in 2004/5. I have stuck to lower-or-equal amp chargers ever since.
i think that chargers and power sources which are bigger than or equals to 1A (like original charger and PC's USB port) are the ideal for charging ouer HD2 (specially when using android NAND)
i think thet chargers which are less than 1A are like someone who wanna take more than 5 persons on his small 5 places car !!!
no ???

No, less Ampere = less current flow in a given amount of time, so by analogy you have 40 persons and you must carry them to point A to point B: if you use a car (5 seats) you need to make at least 8 rides to complete the task while with a 10 seats Van 4 rides are enough. Or you can do it with a 52 seats Bus (1 ride) but the extra 12 seats are'nt making you going faster.
Now, the car is a 0,3 A charger, the Van is 0,6A and the bus is 1,2A.
Is'nt the perfect example and the value aren't at correct ratio but, oh well...

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.

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.

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.

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.

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.
Self explanatory really. I realise any micro USB charger will fit, but I've read that of the voltage / amperage doesn't match, it can fry the phone. How true that is I don't know, but I don't want to risk it. I asked LG, and they directed me to their spares and accessories website. Initially it looked promising, but it turned out the website was terrible, was no info about anything.
I've had a look to find other 5V 1.2a (the specs of the charger that comes with the phone) micro USB chargers, but not had much luck. Any chance anyone could send me a link to a charger that matches the nexus charger? That would be very much appreciated.

I read something that said if you use a charger with a higher amp, that won't cause any problems at all. Is that true? So I could use a 5V 2a charger with the nexus 4 (the original charger was 5v 1.2a)?
The reason I'm so concerned is that when I use my HTC Desire charger (5v 1a), the screen stops working properly. I used it all the time when I first got my phone and the battery in the phone died, and I had to get it replaced. I don't want that to happen again, so I don't want to use a charger with different amp output.

Yes, that's true. The phone will only draw the current that it needs. A 2A charger won't "push" the whole 2A to the phone, the phone will just "pull" the 0.8A or so that it needs.

...*facepalm*. You're not using original charger and you're complain that the one you use doens't works so well? Do you know that original charger is pulling 2000mA out, while your usb-port is pulling between 300mA and 500mA (depends if it front or back usb-port and the quality of usb port). Do the math, 2600mAh battery and 300mA / h. Full charge should take: 2600:300 = more than 8.5 hours.
With original charger S4 recharges from 0 to 100 in 1h 49minutes. If you take a solar charger it will charge even slower (like 48 hours for 0-100%).
Next time try to use your brain before complaining.

Your Samsung power brick has the cable physically attached to it? If not, you can just use a longer cable with the Samsung power supply.
The included power supply is 2 Amps, whoever is getting long charging times, make sure you use either the original Samsung power supply, or comparable in amperage supply.
Mine charges in 2 and a half hours.
Mine takes 2 to 2.5 h to charge from 0 to 100 percent. You should only use the new white charger, it's more powerful than the black one from s3, it's output is 2.0A ,old one is only 1.0A. Newer use other chargers as they may mess up your battery or phone.

I have to check the amps but based on google the Nokia Charger is at 1.3 Amps. I need to remind myself to switch the short Samsung to longer Nokia cables.
Is it safe to get a higher Amp charger, the one that the iPad uses to charge my S4? No drawback execpt for a faster charging time right?

Take it this way, grilling meat takes for example 45minutes to cook completely. You take it to some powerful furnace like 2000degrees for 5minutes then what do you expect from it to give you back? Well cooked meat or some burned meat outside and maybe raw inside?

put it this way... the s3 comes with a 700ma charger. it charges a bit slow. and has a 2100mah battery.
the s4 comes with a 2 amp charger. thats 2000ma. it doesnt charge slowly if you use this charger. i personally am going to pop it on this charger when i get home from work and then keep it on my 700ma charger overnight... no reason to waste that powerful output, it will simply waste electricity.
make sure:
1. you use the charger that came with it
2. you use a cable thats as long as (or shorter than) the stock charging cable. longer usb cables tend to charge the phone slower.
also keep in mind usb ports charge any phone slowly. the s4 will charge even slower on them because the battery is oversized compared to most.

Because i see in the normal charger, the output rating is 5 V 1,2A.
I am currently using my previous samsung charger (5 V 0.7 A) to charge my nexus 4. It is safe or not to do this?
I dont mind for if the charger take more time to get my battery full anyway.
Thank you very much

It should be fine but yeah, it is going to take significantly more time to charge your phone

So it is safe...
I dont like our charger because the cable itself it's too short.i need longer cable so i can do couple thing when my nexus is being charged.
Thx you for your information pal

No problem. You'll start running into problems when you use a charger with higher Amps than what you phone charger puts out ie a tablet charger. Good luck!

A piece of electronic equipment only uses what it needs as far as electrical current is concerned. I am using a 2.5 Amp cigarette lighter charger with my Nexus 4. I could have used a 5V 100 Amp charger if I wanted, although it would have been tough trying to fit that giant connector into the micro usb port.
^ +1 You should have no problem using any charger that adheres to the USB spec and provides 5V reliably.

Really? wouldn't it fry your battery as soon as you plug it in?

Nope, it would just insta charge your battery pretty much.. It probably would damn/fry itl; but only because the battery got hot.

Even that is unlikely because the phone regulates how many amps to draw. The current allowed is regulated based on multiple factors including the battery temperature and the charge present in the battery.

Well the second scenario was if said bits failed
amps / volts
Think of volts as pressure, and amps as volume of flow.
Think of a conductor as the empty space of a pipe, the insulation as the pipe wall.
Higher volts needs stronger pipe (conductor insulation). The limited insulation in most modern electronics will burst if to much pressure (volts) is applied, causing a short and a fried device.
Higher amps requires a larger pipe (conductor) and will most always be limited by the size of the pipe, or the amount of volume consumed downstream.
If a charger puts out 100 amps and only .75 can fit through the pipe under a giving pressure (5 volts), then only .75 amps will be able to come out of the charger, without damaging anything.
