Good car charger to buy? Phone dock?

I heard there is a difference between car charger. Some charge faster than others. I just bought one off ebay for 5 bucks. Damn thing charges maybe 10% after 30 minutes in my car. My nokia n95 car charger changed the phone from dead to full in 45 minutes and that battery lasted the same if not longer than the nexus one.
Also which phone dock should I buy, now that you can't buy a google/htc dock. I want one that is visually appealing.

This Motorola charger has been great. I can't remember how much its rated, but I think around 850mH.

You can still purchase a google/htc dock here and apparently they have cases too, which I've never seen..

Use this one too and love it

i use Griffin's. it has 2 usb, so it's good for charging my ipod and n1 at the same time. the bad side is, i think it don't have enough energy to charge my n1. it only slows the batt consumption. i use it a lot when i go for travels because i use my n1 as gps.

It makes sense to get the official N1 car dock. It's a sweet dock that can also be used to plug the charger directly into the phone.

I love my N1 car dock use it as a GPS and mp3 player. Charges ok while I'm drive and using all the features.

It's just so expensive.....and you have to take off your case.

Is it ok to use a car charger rated at 1.2 amps? Do we need exactly 1 amp or 960 m amp?

The phone draws whatever it wants. The rating on the charger just says what the charger is capable of outputting. The official nexus car dock, for example, uses a cigarette lighter adapter which is rated for 2 amps while a usb cable plugged into your computer is only rated for 500ma.
The problem with buying 1A car chargers is that the phone may not know how much it can draw and will default to taking just 500ma. Every charger has some sort of way of telling the phone what it can supply, such as shorting out the 2 signal pins or putting a resistor between them. every manufacturer has it's own standard and it's a guessing game as to whether it will pull 1A or 500ma. Iphones, for example, will not draw any current at all unless it sees the exact set of resistances across the 2 signal and ground pins which is just silly.

[Q] new to nexus !

does the phone really charge so slow??

There's already a few threads discussing the slow charge time. Seems to be an issue for many. All Galaxy S phones seem to take a lot longer to charge than say an iPhone.
My Nexus S always makes it through a good 16+ hour day without needing a charge, and I always charge overnight while sleeping, so I haven't personally noticed this as an issue.
Like any smartphone these days, it's probably a good idea to just partial charge during the day when you're in a situation (like the car, or at your computer desk) that lets you. It's not necessary to do the full drain, full recharge only with the current battery technology.

Its odd, mine and my wife's phones take maybe 3 hours to get to full from sub30% yet that seems to be the outlier.

Are you charging it on the supplied wall charger or through a computer's USB port? It charges significantly slower through a USB port than from the wall charger

Wall charger charges a bit faster than USB since its rated at 700 mA rather than 500 mA. Best bet would be to go with a car charger that charges at 1000+ mA.

i used wall charger..

Hi guys i have a wall charger from my nokia n97 mini which is 1200mA. Can i use it or i will destroy the battery?

If the voltage is correct, the amperage should not be an issue...the phone should only draw the current it actually wants/needs.
But bear in mind, if your phone blows up, it's not my fault, I have no experience with that charger or it's actual ratings.

Car charger for Samsung Galaxy S4

Has anyone managed to get a car charger for this phone?
I've just tried to charge the phone with my car charger modded to "AC" mode by shorting the middle pins... and the S4 gets nada...
Have they changed the charging mechanics?

Is that what's going on? I was wondering what the heck was wrong with my charger!

Yup, the car charger still charges my old HTC, even with the Samsung cable... so there's definitely something different inside the charger...

I have a 2A usb car charger with generic cable to charge my devices. It's nothing special, but it works with my S4. Hope that helps.

I have this charger and it charges my GS4. Of course, I bought it 2 years ago.
EDIT: I guess it helps when I paste the link. Duh... http://www.amazon.com/Verizon-Vehicle-Charger-USB-Port/dp/B003NA0658

I have a 500mA car charger and it didn't work. Even though it worked on my Xperia Z. I bought a 2A charger from Maplin and it works just fine.

I also have the same charger works just fine.
Sent via Galaxy S4

Hmmm will have to look into getting a decent 2A charger then and NOT modifying it...

So I opened up my car charger and un-modded it back to original and it works like a charm now

I've got a 1A Belkin car charger and it seems to overload after a while when charging my gs4.
The green light on it blinks and my phone makes that sound when you plug in the charger.
Takes a while for it to happen but gets more frequent the longer you have it plugged in.
The charger works fine with my gf's nexus 4.

I'm using the Motorola charger (big blue circle). Got it for my Razr Maxx a year or so ago (I've gone through like 4 phones since then) and it works wonderfully. It's the best micro-USB car charger I've ever seen. Coiled cord, huge blue light (but not too bright since it's an ambient-style light), and charges quickly.

Seriously, the best car charger I've ever owned. 950mA is also one of the highest car chargers I've used.

I used to have that same motorola charger but I just switched to this one by SPIGEN: http://www.amazon.com/gp/product/B0069EGLFY/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1
It charges at the same amperage as the stock wall charger that came with the S4. I use the Galaxy Charging Current app to check.

Do you use it with the original cable or a generic one? I read that there are some differences in charging amount using also different cables. This SPIGEN Car charger looks very interesting. Thanks!

I have tired a few most only charged at 400-500 m-amps (aka running with gps and screen on discharged it faster then it was charging) with some random picks at fry's i found one that was marked 3 amp charger that whould do 780 m-amps so the phone still makes head way chargeing while being used as GPS
FYI the tool i use to measure says the Samsung charger is 1900 M-amps and my apple ipad charging brink is 1400 just for reference.
tool is Galaxy Charging Current Lite i would link it but the forum will not let me

You can also use elixir 2, the battery stats will give amps while discharging and change when charging. I think it uses the current_now as reference.

I have a 2a usb car charger and I just use the usb cable from the phone. I bought the car charger from best buy.

Different USB cables do pass different current even if using the same charging main. From tests I've done so far, a generic 3 ft USB 2.0 cable I randomly purchased online only allowed around 400 mA. An old Blackberry Torch 9810 cable allowed around 1200 mA. Original cable that came with the S4 allows 1900 mA. These numbers are from using the original wall charger main that came with phone.

I bought an anker car charger and mediabridge charging usb cable and it's a great combo. The images of the anker car charger is different, should be dual usb ports.

I don't know the exact current I'm getting, but from the battery monitor widget app, I'm seeing at least 1amp or higher of positive current.

charging galaxy s4 i9500 with 2.1A and not 2(stock)

http://www.ebay.com/itm/3-1A-Dual-U...S_Cell_Phone_PDA_Chargers&hash=item565a917530
hello
My stock charger is us for galaxy s4 (samsung regular charger)
and then I found this (link above) with 2.1A
is it matter charging via 2.1A and not 2A? what is the different? it will charge faster/slower?
thanks

In Stock kernel there is current limit 1.9A. So everything above it, will be the same as 1.9A.
In reality, you will find that even 2.1A charger doesn't supply even 1.9A. Chinese charges definitely don't supply current thay claim. And beware of them - you may fry your device by such cheap charger.
Also, it heavily depends on USB cable as well. It has to be very short and very thick.

I have a Mediabridge car adapter that has a 2.1 amp charger on it. When I charge my S4 with it it barely charges faster than the 1 amp charger does. I think it charges at either 1.3 or 1.7 amps, sorry can't remember exactly.

I don't have the equipment to measure it exactly. So what I did was charge my phone from 50% for 40 minutes on my stock Samsung wall charger and then recorder the percentage it increased. I then took that number and assumed it was charging at 2 amps and used it as a baseline. Then I did the same test with my car adapter and recorded the results. The I figured out the percentage difference and came up with me estimates. I just don't have the data in front of me anymore but I remembered it being somewhere between 1.3 or 1.7.

Chargers, power supplies, etc, don't "decide" the amps that go to a device - the device "draws" a certain amount. Just because a lamp is plugged into a 20amp circuit in your home doesn't mean 20 amps are going to be shoved through the bulb.
So if, as sorg says, the phone is only going to "ask" for 1.9a, you could plug it into a 5 amp charger and it would make no difference.

You already got your answer above.
No, your phone will NEVER charge faster than 1900 until a developer comes along and figures out how to hack the system to allow this. And it would be a potentiallly STUPID idea to charge faster than Samsung has deemed safe.

Which car charger?

Hello all,
as the title says, which car charger would you guys recommend?
i would like to have 'fast charge' (if that's how Samsung calls it), but, i do not see any car charger offered on samsung website?
i have 'dash charger' from OnePlus 3T device, but, i do not think it can be used?
Thank you for your time and suggestions.

Any charger that supports 2A and has USB port works fine. Use my sammy USB cable to plug in. Charges well even in daylight with satellite gas is active.

You will definitely want one with Qualcomm QuickCharge 3.0, it makes such a difference in charge speed. I have this one: http://amzn.to/2f9KVh0, I love Anker for all my charging needs! It costs a bit more than the other options but the perfect 5-star reviews speak for themselves You will also want to get a 3ft USB A to C cable like this one: http://amzn.to/2f9KVh0
Enjoy your awesome new device! With that charger I can go from 50% to 80% in just 20-30 minutes.

No way! I call you on that one. Our 3 year old devices can't quick charge without damage. Please do not post such info without knowing 1st hand. Our custom kernels limit fast charge to 1.8 A for a good reason.

Sorry I thought this was the Galaxy Note 8 (new phone) forum. Confusing from the XDA app... Having a QuickCharge charger won't hurt on old devices, they will charge at the normal 2.1 or 1.8 amps. But I agree in this case (old tablet) it won't help (but it's not like the newer charger will damage the device--they scale back their charging gracefully).
