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.

Charging from USB?

I keep getting a red X Through my battery when plugged into my laptop to charge, is this normal? I really dont want to plug into the wall to charge

Really hope this doesn't become the case and that it will charge off of any USB charger...in particular like the one in my car that accepts USB Devices.

My friend has a galaxy and has the same issue, idk if its our laptops or what

Okay this has been address. please search but ill answer for you.
This device uses 5v 2a to charge. Hence the wall unit. you computer is 5v 1a or 1.5a (its not enough)
The device will maintain and in some cases when screen off slowly charge when plugged into computer or usb adaptor with the red "x" through it.
you can find a usb adapter cable which has a switch to allow you to charge while connected to a computer. its a data and charge switch. search for it. i think its on ebay.
also you can find on amazon or google shopping wall chargers for the p1000 which work for like 8$

Having this Y-cable will also help with the fact that the USB cable that came with the tablet is so sort. I have a lot of 5V power supplies around but they are all from 50ma to 1a. Can't believe this thing needs to much power to charge, I would think that 1a would be enough just to maintain it when in use.

OK, I got a couple Y/Split cables and I still have red X when plugged into two USB ports, I even tried two ports that are on different controllers... as well as two USB3 ports in my laptop. I even tried my desktop. No luck.
Has anyone gotten this to work?

The red x will show up if you are charging with anything under 2A. If I remember correctly usb 1 puts out 100ma and usb 2 & 3 put out 500ma. Even with a Y adapter you will only get 1A. If the screen is off then you will charge the battery however with the screen on, you are using the same amount of power that the usb is providing. Therefore the x because the battery is not charging.

With the adapter I posted about above, I never see the red x and I am charging off USB 2.
-EDIT-
To be clear, I am using a 10.1v not a 10.1 - there could be differences, but I doubt it.

Battery charge time

As I sit here and wait for my phone to get here...9 more days...how long is the charging time from a battery with 20% charge? Also does the port have the same connection as a droid X? I am really not looking forward to having to change my chargers...lol

From 20%?
About 2 hours

The connection is micro usb which is the same as the droid x. You should be able to keep your droid X charger and use it as a spare or a work charger.

I use juice plotter still on my phones. at about 20% left on the battery, it always gives about 2.5 - 3.0 as the expected time to 100% charge when using the OEM charger that shipped with the phone.

A charger that can provide 2 Amp current. A lot of the wall chargers are spec'ed at 1 Amp. The USB port on a PC gives only 0.5 A, or even 0.1 Amp depends on the port or if the PC is powered or on battery. I also saw some microUSB cable is spec'ed as can handle 2A. Note sure how much difference it makes.

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.

It only charges via usb when the screen is off or when the device is off. Try plugging it in checking the battery % leave it awhile and then recheck the battery % you may find its gone up!

Looking for an additional 1.2 amp charger.

I tried calling Google Play device support. They said they don't replace chargers, and I should just use a standard micro USB cable and wall charger. The problem is, I have not been able to find a 1.2 Amp charger of any kind. Anything lower will charge the phone more slowly, and from what I understand, unless it's properly shorted out (I think), anything higher will not necessarily work properly with certain devices.
Can somebody please help me find a good replacement charger that won't charge the phone more slowly than the one the phone came with?

I believe Ipad chargers do 2amps, or try a 1amp charger since i haven't seen more than 880ma from my battery widget when charging it.

What about this? http://www.amazon.com/gp/product/B0073FCPSK/
USB Port 1 (Designed for Apple products) Compatibility
iPad @ 2 Ampere Max.
iPhone / iPod Touch @ 1 Ampere Max.
Others phones / GPS / Tablet etc. @ 0.5 to 1 Ampere Max. (May not support charging of some devices)
USB Port 2 (port close to LED, designed for non apple products) Compatibility
iPad @ NOT Compatible
iPhone / iPod Touch @ 0.5 Ampere Max.
Others phones / GPS / Tablet etc. @ 1 to 2 Ampere Max.
Would the non-Apple port work?
Somebody mentioned this to me on another forum: you gotta be careful with those dual chargers. sometimes the higher current port is limited to apple devices (i think they have a couple pins in the cable shorted)
What exactly does that mean? The product I linked to, does it have this problem?

Disregard, forgot what section I was in!

Just do what was suggested at LL.

that was not helpful at all. I made a topic here for a reason, LL was being completely unhelpful

I'll be honest. I don't like that Blackberry charger because you can't remove the USB cable from it.

No it's not gonna hurt the battery. The phone (or better a battery controller) controls the current that reaches the battery. So no matter how powerful a charger would be it will not charge above a certain current.
