Chargers

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.

Cheers for the replies, you have put my worried little mind at ease!

+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.

[Q] charger replacement for kindle

can i use any charger that can fit into my kindlle fire?
i have a charger of LG optimus one and it fits exactly.
i cant find shops selling kindle fire charger here in the philippines.

the original has 1.8A - would try to get one that has around this value
with a charger under 1A i'm pretty shure you'll get charging problems or at least it lasts very long
basically you can use every usb charger ...

Yes you can as long as a charger has equivalent current as the original charger.

I lost mine and just been using the iphone wall charger with the mini usb cable and it's been working fine. Does charge pretty slow but that's all i can do for now.

Any USB charger will work, but one with less current won't charge as fast.

No... I got a charger off ebay and it said it was for the Kindle Fire, but it was only 1000 ma. and I had all kind of problems, There are several threads on this already..Get one at least 1.8 amps and you'll be ok..

The Kindle Fire will recharge from a powered USB hub or computer just fine, and that's only 500 mA. The USB spec doesn't allow for anything greater, so you may run into incompatibilities with other chargers since compatibility is the main reason we have specs. Hopefully manufacturers are talking to each other about how to make fast chargers, but, given Houndog101's experience, it doesn't seem like that's always the case.
The Kindle has a 16.3 W*h battery, so you can calculate how long it'll take to charge given any current (5V * current = Watts), if you account for the loss due to the Kindle being on at the time. A standard USB port is going to take at least 7 hours to fully recharge the Kindle, and probably more like 10+ if WiFi is on. So I'd definitely go for a 1.8 A charger, and hope for the best. Don't spend too much since it might not work unless it's specifically made for the Kindle.

Belkin F8Z630 charger
I've bought several of the Belkin F8Z630 chargers and been very pleased with them. Not cheap, but they deliver a solid 2.1 A at 5 Vdc, they can handle any input 100-240 Vac (basically worldwide usage), and they have a nice rotating plug feature that is handy in some tight spots. Works great for charging the KF quickly.

I found one in my car from an LG that chargers it just fine, and in a timely manner.
What happened to the stock charger? The one that cane with my fire did not work at all

Need help. My Transformer won't charge anymore

Hi,
I hope someone can help me. My Transformer doesn't charge anymore since yesterday.
Tablet was around 10% when i put the charger in, but the message 'Connect your charger'doesn't go away.
Strange thing is that whenever i plug it in and TF is off, it will turn on, so I guess the wall charger and cable are functioning.
Also when connecting it to my PC I can sync.
I've tried already all the solutions i could find online:
- put the wall charger in the freezer --> didn't work
- cold boot --> didn't work
- factory reset --> didn't work
- tried a different wall charger and connected the wire to a portable battery --> didn't work
- flashed the ROM again --> didn't work
The only way now i have for charging my TF is by USB (connected to PC while turned off). It will charge this way but it takes about 3 hours to get 10% charge from this.
Anyone had this happen already before?

So you tried multiple Asus wall chargers? with no luck? A standard USB charger will not work as those have an output voltage of 5+ when the tf requires 12+.
Sounds like you have a bad charger, you can join the club of thousands... It is a very common issue and not always resolved by the freezer or fiddling trick. If you are able to trickle charge via a PC connection then your cable and tf should be good.

No, I tried with a different wall charger (from Motorola). I don't think it's the wall charger though, but to make sure I wil connect it to a phone and check if it's working.
It just feels like the cable and wall charger is working as it should (tablet powers up or screen turns on when I plug it in), but the tablet refuses to charge.
Could it be the pins?

And the motorola USB charger puts out at least 12 volts and not just 5. Is it the wall charger for the zoom? I was UN aware that the zoom used a USB type charger (similar to the tf).
Once again, you can't use just any USB wall charger for the tf... 99% of chargers put out the standard 5 volts which is enough to trickle charge a tf and to slightly charge it in done cases when powered down. I am only adamant about this this because I have sewn this post a hundred times, and 99 of those times it was the charger... Many people don't realize the tf USB charger is very coherent then what most folks are accustom to, even though it looks and acts similar to others.
The only way to confirm is to find someone who has a tf and borrow their charger, our go to radio shack and buy the charger I listed... Which you should do any ways because it's is way way better, my charging cord over all length is 10ft. Beats the hell out of the 2 or 3 you normally would have.

Thanks for your replies.
You're right, the Motorola wall charger is only 5v output. It was the one I got with the Milestone. I do start to believe it might be the wall charger after all now.
Unfortunately I don't know anyone else with a TF (anyone reading this lives in Ghent, Belgium with aTF?). Radio Shack isn't an option either since I live in Belgium, but I'll try to find overhere or online.
Anyway, appreciate your help. Might try the freezer thing again in the meantime... you never know.
When you connect your TF to a pc on a usb 3.0 port, should you be able to see the TF charging? Or no way to get more the 5v from this too?

USB is 5V. No exceptions.
What you can do is build your own PC charger, like the one in my sig.

I might try that, but only if I have no other choice (i fear i'll blow up my TF while doing that).

usb chargers are 5v only and will charge but take all day. The TF charger uses the physical usb plug to do double duty. transfer data via usb and charge device using 15v when the charger block sees a gnd signal on pin 7. Charging is not usb. There are several after market chargers that have variable output voltages and an asst of connectors (usb being one) best one is dynex video charger. Also you should not attempt to flash a ROM with 10% charge as you could get stuck in the middle of a charge and have problems.

Well, it was the wall charger after all. Went out to buy a power adapter with 12v and 1000mA output and the tablet is charging again. Many thanks to all people that replied and tried to help me.
For your info: ipad or galaxy wall charger aren't working with our TF's, they both only have an out put of 5v.

Never allow your charge level fall below 30% because it will cause your charger to overheat and eventually stop working.

car charger

Any idea why I can't seem to charge my Nexus 7 with my car charger?
i have both a generic Micro USB charger and I have one of the dual USB ports that you put into the cigarette lighter. It wont even acknowledge that I have plugged anything into it.
i have used the USB port to charge MANY different cell phones my old Dell Streak 7 and even a friends iPad.
Any ideas?

I think the N7 needs 2A to charge. a single USB is 500 mA and the dual 1A, so I don't think there's enough power.
Also check if the output of your microUSB cigarette charger is 2A

This one will work: http://www.amazon.com/gp/product/B0090SVY3K/ref=oh_details_o02_s00_i00
It charges at the same rate as the stock AC charger.

The N7 is one picky device for charging. I have several chargers for the car that charge the iPad but not one will charge the N7. Same as AC chargers. This set works for me

This is what I use and it works just fine. I use it to charge my N7, GNote, Nook Color or my grandsons IPhone and it works equally well on all of them.
BTW, it prime available if you are a member.

Dual Nexus 4 or Nexus 4/10 Car Charger

Has anyone found a dual car charger for two Nexus 4's or a Nexus 4 and a Nexus 10 whilst in use?
Most dual car chargers seem to have one output to charge Apple devices at 2A plus another output to charge non-apple devices at 1A which is not what I need.
Thanks

I've managed to find something but it seems to be unavailable in the UK

Monoprice has plenty of these. I love their products and pricing.

It might be possible to charge two Nexus 10 tablets or two Nexus 4 phones using a dual iPad charger and power USB cables as described in the first link below.
The second and third links are items from Amazon which might work.

Have you tried to charge your nexus 4/10 with a 2.1a apple USB port? I tried it with both my nexus 4 and 7 and they do not deliver more than 1a. I just ordered the powergen dual USB. It will only give 1a to android devices according to the guys at the nexus 7 forums. 1a is enough to slowly charge my nexus 7 in the car with maps running but im not sure about the nexus 10. We need a car charger specifically made for android tablets that can output more than one amp but I don't know if there are any on the market yet.

If you read the article in my first link above then that says that a dual iPad charger with the correct cable should deliver 2.1A.

Here are some Amazon customer reviews showing that a dual iPad charger can charge a Nexus device at 2.1A when using the correct USB charger cable.

Unless someone tested it with the nexus 7 or 10 im still skeptical. Anytime you see the 2.1a it's designed for the Ipad. Just read that article and it doesn't say anything about android tablets just ipads. Im sure they do output 2.1a but just to ipads, android devices will only get 1a.

Sorry for offtopic a bit but is it okay to use 2A to charge the N4?
I mean does it kill the battery faster or it is totally fine?

i just read the reviews, just because it shows AC charging it does not mean its output is 2.1a. AC charging just means that its using a charger or cable that has the D+/- pins shorted. I have a moto 700mah car charger that shows AC to both my nexus 4/7 but only delivers around 6-700 mah. What im saying is that it probably wont output more than 1a to an android device. 1a is more than enough to charge a nexus 4(or any other android phone) with nav on but is a bit too slow for tablets. If you do get this car charger let us know if it does output more than 1a. you can use current widget app to find out how much current the phone is receiving from the charger. Im still looking for a car charger that can deliver more than 1a to an android device.

yes it's fine. The nexus 4 will not draw more current than is safe for the battery.
