can i use charger from motorola v950 on EVO?
thanks
Any micro usb charger should work. Not sure what that phones uses but if they look the same it should work fine.
yes is micro usb
Not all chargers are alike and some kernels will not allow certain chargers to work correctly. Amps and voltages can vary as well. Some will lock up your screen when you plug them in.
I have a wall charger that is for my samsung. It did not charge up my EVO with CM6 but when I installed MYN's ROM and AVA's ROM they would charge. I installed King's Kernel and it works fine. CM6 will not take the charge.
Also the cheap battery charger and battery from Ebay does not like the EVO, DROID X or my Samsung. I think the current is too high and it freezes up the phones. I would not risk them being damaged or overcharged.
If you notice your phone getting hot while charging or the screen locks up then unplug(captain obvious )
oh ok well i just ordered this battery from ebay
http://cgi.ebay.com/3500mAh-Extende...ps=63&clkid=5314589341353148697#ht_4146wt_911
so will see how it will work,,???

That's not how current works. The current rating on the charger sets the maximum amount of current the phone can draw from it, it does not set the minimum amount of current that goes into the phone. A 1000mA charger and a 2000mA charger are functionally identical if a device that only draws 500mA is connected to them. Now if a device like the EVO that can draw a maximum of 1000mA is connected to a charger that can only supply 500mA, then either the phone charges more slowly or the charger pops its overcurrent protection and it stops working. Chargers that can handle more than 500mA have their data wires tied together so that the phone can recognize that it is in fact capable of more than 500mA. When you connect the phone to a computer or a charger that provides only 500mA the data lines aren't tied together, so 500mA is the most the phone will draw - which is good since standard usb ports are only rated at up to 500mA. All MicroUSB chargers should be 5V, that is the standard voltage for the USB specification. Now dodgey chargers may have bad regulation in them, which could mean that the actual voltage is more or less than 5V or it has an additional AC ripple that could cause problems.
so can i use charger from motorola? on that charger is 5V-850Am..

Should be fine.
The stock HTC is 5V-1.0A... your charger will just take slightly longer to charger the battery. No big deal

dont buy charger from ebay..)) go to local shop and get one universal for samsung.. the charger is the same as for SGS1 mate....
second thing is the same - for car charger...just buy a charger with micro USB even for HTC or NOKIA..they are all the same...
dont make things complicated...
W.r.t. car chargers: They are not all the same !
The difference is in the charge current they can support.
There are 500 mAmp versions;
There are 1000 mAmp (1 Amp) versions;
And then there are a few 2000 mAmp (2 Amp) versions.
I would at least get a 1 Amp version to be sure that charging is more than an active SII would alreday consume (GPS, Bluetooth,...)
I myself bought a 2 Amp version.
(Note the standard Samsung Wall-plug delivers 700 mAmp.
alright thanks!!!

Have you used the 2A charger with the SGS2? If so did you experience any problems like overheating, stopped working etc?
How about charging time is it any faster?
I'm thinking of using my old HTC charger 5v 2a and would like to hear your thoughts
Thank you.
I always used 1A 5v car charger for every phone I owned. but with gs2, it made me sick. overvolting everytime, both with 1A and 250A (btw better 250..) and it causes freezing.
more A isnt better, our galaxy has an internal chip wich brings A to 0.7A anyway, even with 10A input.
buy an original samsung car charger
thanks for the reply!
I just bought a 2A charger. I'll let you know my experiences.
Please do! Thank you.
I too would be interested to hear how your 2A charger goes. Especially for long journeys (e.g 2 hrs+) with GPS on the whole time!
I just bought a 1200mA wall charger
It's Nokia's Fast Micro-USB Charger (AC-10) for 10 euro inl. shipping from ebay
l let you know my experiences
I have a 2 A car charger. Originally sold for the Ipad2.
Works well - no freezing, but the phone still tends to discharge very slowly whilst using Sygic with GPS on and bluetooth. This is a common issue on the SGS2 and is NOT solved by a high current charger. It seems that there is a limit to how much current the phone can take (possibly software implemented) and there is nothing to be gained between a 1A and a 2A charger
Thank you Mahniex for taking the time to post your observations.
Thank you Mahniex for your testing,
I also have a 1A car charger, but same problem here. After 200 Kms of driving with GPS on and BT on, the battery is draining so fast from 100% to 0%, that I can't use it a lot.
Maybe, there is also a problem with the cable. I use a Sync/charge Cable. Maybe if I could find one with only charging capabilities, it could be better.
I don't exactly know...
i bought that Motorola Rapid Car charger recent and have been using it about a week now. i've noticed that it doesn't seem to charge my Thunderbolt any faster then it did when i was using the Thunderbolt's USB cable with this USB car charger adapter.
so, my question is, why is it called "rapid" if it doesn't charge any faster?
and i suppose secondly, is there an actual microUSB charger that will charge the Thunderbolt faster?
they make one for the iphone that will fully charge it in 30 minutes so i know they are out there.

Maybe you should try this one.
Install the battery monitor widget. Monitor the battery for about 20 minutes while charging. Tell us what the charge current is.
Does the Motorola charger include a cable? If not, you may just have a weak cable. I have seen cheap cables with wire so thin that the charging current is no better then charging off a weak USB port.
My experience has been that the phone typically recognizes car charges as USB charging and uses a different charging profile. My solution to that is use a wall charger through an inverter or a kernel that doesn't use radically different charging profiles for A/C and USB.

No need for that.
Cut a small piece of aluminum foil. Carefully place it where it shorts the two center conductors in the charger. Plug the USB cable into the charger. Make sure the foil stays in place over the two center conductors.
It is now a high rate charger. (assuming it can put out 1 amp.)
The limiting factor is typically the usb cable itself. Most usb cables can't support the 1amp that is provided to it. Since you used the original usb cable that came with the thunderbolt (that's been "shorted" as mentioned above" ) it will be just as fast as the moto car charger. the 1amp charging rate that the moto charger charges at (i have one) and that the original one charges at are already "rapid". if you plugged a normal usb cable from somewhere else into the other usb car charger, it'd be much much slower

The stock charger is what shorts the connections. The cable is NOT shorted on the two inner pins because they are the data connections used for connecting your phone to a computer.

To meet the USB charging spec (which the TB uses), the two inner (data) contacts should be shorted with no more that 200 ohms.
But, the cable can also be an issue for rapid charging. The voltage drop for a 1A/5V source, across only .5 M of 28 gauge copper is ~220 mV. If you use a longer cable, there's more voltage drop. The TB likely current limits itself when the voltage drops below a certain threshold. Best to buy 24 gauge USB cables, if you can, especially if getting longer ones (monoprice has them).

I think its a matter of rated output current. BUT on the other side, the phone must be capable of drawing/using that much current. If the adapter is rated for more current than the phone can charge, the "extra" current wont be supplied.
Initially, Moto's standard car chargers output 5V and up to 550ma max (just like a standard PC USB port) so they didn't charge phones all that fast. Moto then came out with chargers that had higher current output, so they were capable of charging the phones "faster" than the original car chargers (but on par with the home/travel/AC chargers) and called them "rapid car chargers"..
Today, the current output on the Moto SPN5400A car charger is 0-950mA, and I've seen it sometimes referred to as "Rapid Car charger."
But as far as I know, Moto no longer makes/sells the lower current car chargers, and their web site only shows one MicroUSB and one MiniUSB car charger for sale, both of which appear to be of the 0-950mA output variety.

Just because someone makes such a charger for the iPhone, doesn't mean one must exist for the TB, or other phones, does it? I know the iPad uses a 2A charger. What happens if you connect an iPhone to that? will it charge faster? I guess that depends on if the iPhone is capable of drawing more than 1A to charge it.
I've not seen a "home" or AC charger that can charge the TB any faster than the Stock 1A charger. Does such a thing exist?
A proper car charger with 950mA to 1A output should charge the TB at almost exactly the same rate as the stock 1A wall/AC charger.
And btw, the Moto SPN5400A car charger DOES charge my TB in about the same amount of time that it takes me to charge my TB at home with the stock HTC charger. So while its not "rapid" compared to the stock home/travel/AC charger, its "rapid" compared to PC USB Port charging, or a plain lower current car charger.

I made a charger for my motorcycle. I use it as a GPS, screen on MAX, phone active with marginal signal. And I wanted to actually charge the battery at the same time. I did a lot of experimenting with the Thunderbolt. It would not exceed a pull of about 850ma from the supply, even at 5.5 volts. IMHO, you are wasting time looking for any charger over 1 amp.
Also, even with about 850ma in, not much over 500ma is getting to the battery. So a totally dead battery is still going to take between 2 and 3 hours to charge, no matter what charger you have. And twice that long if the charger looks like a PC USB port.

I was asking because of the OP's statement about knowing "they must exist" because they are out there for the iPhone.
I'm perfectly happy with my Moto car charger, and how fast it charges my phones.
I am looking for reliable car charger for KF. Any suggestions?
It needs to output 1.8v 1.8amps .. which is more than most car adapters will support.

I think you are wrong about the 1.8v, my charger says 5v @ 1.8 amps, which means you could use any usb charger rated at over 1.8 amps.

Meant to say 1.8amps not volts. Most car adapters are 1amp or less. Many car lighters (the socket) max out at 1amp. Utility plugs may go higher, but the charger plug you use itself needs to support it.
You are right about the 1amp though, anything over 1amp will cost quite a bit more than the few dollars a 1amp adapter costs . In that case it would be worth looking into seeing if the manufacturer of the Kindle Fire sells a car charger, but I would only use that for trips, there is no way I would leave my KF charging in an unattended automobile.
Your best bet would be to find a car charger with a USB port on it that can support an iPad 2. If it can charge an iPad, it can charge the Kindle. Tons of good options on Amazon.

Wouldnt any cigarette lighter plug with a USB connection work?

I bought the "GTMax Black 2-Port USB Car Charger Adapter 2A" from Amazon, it has two usb slots, one with 1A and the other 2.1A. Works great on my Bionic, have yet to try it w/ the kindle though.
I'm using a 2AMP charger as wel and it charges just fine. Most chargers designed for the IPAD will work well. Just make sure it has a regular USB port on it and not the apple connector
Any USB charger with a micro connector will charge it provided the KF is using less power at the time than the charger is able to provide. It doesn't have to be rated for 1.8 amps. I've used everything from a 0.5 amp Motorola RAZR charger to a 2.0 amp charger and they've all done the job. The only difference was the time required. I can't see why it being a car charger would make any difference either. My T-Mobile 1 amp car charger worked just fine with it.
Most USB chargers will work
Hi,
As others have said, most USB chargers will work. However, there is one exception that I ran into recently and its well documented on the forums here - if your battery gets too flat. e.g. you left it at home when you went away, it will need at least 5V @ 1.6A to actually recharge.

I am aware that many of these dual USB port chargers dont actually charge any faster than 1amp.
Does anyone know of a robust dual charger that can swiftly charge my Z1, without having to turn everything on the phone off?
Also, will charging via the magnetic charging port and the mini usb at the same time, cause any issues or charge the phone faster?
If i am being stupid, please forgive me.
Take a look at the Anker chargers.
As far as I am aware you cannot charge your phone by simultaneously using the magnetic port and the usb port. Most likely the first one to be plugged in will take priority. Q

Thanks, I bought an Anker 150000 amp. It's dual. I was looking for an adaptor for a wall socket. Just worded my request wrongly it seems.
I have a Sony mag-cable, and a sony wall charger.. all are stock sony supplies bought directly from the local Sony retail store.
When I plug my mag-cable to the side, it charges it - as expected.
When I then plug the USB cable in, which is connected to the wall charger on the end, the mag cable STOPS working.
Using a voltmeter connected to the prongs on the side of the phone, the voltages dropped to near 0 as soon as the usb was plugged in.
I'm using a NUT's 4.4.4 with a locked BL and stock kernel/everything else.

I don't think you can charge them at the same time. I don't know much about them, but you might also look into 4 or 6 port chargers too.
I use the magnetic charger, it charge quite fast as. But I think the voltage limit for magnetic is 1 ma.
But for usb, I charge with Sony fast charge USB power bank, it's charging rate at 2.1 ma.
It's very speedy to charge. So I suppose that having a charger with 2.1 ma charger will fill up your battery better than 1 ma.
Anker chargers are really awesome, been using them for months...
What can you say about Lumsing power banks?
