Wall/usb/webtop charging

So the wall sends out 1000 ma and USB sends 500 ma.
What about webtop? Anyone know?

Now that would be interesting. 500,000 volts from a USB. Needs a flux capacitor.

Hey thanks! I already have a dock though.
In my post I asked what the charging output was for the HD dock.
Sent from my Atrix using XDA App

USB 2 is 500ma, USB 3 is 900ma, Moto charger has 850ma rating on it. If you have a USB 3.0 port you can use you'll get enough power from that. I use the 3.0 on my laptop at work, and it charges fine.

How can we find out the charging output of the multimedia dock?

Do the differences matter much? Just one takes longer to charge then the other?

Yes one charges faster that's it. For heavy users like myself, getting the most juice as conveniently as possible is a plus.
I also like to charge my phone on the dock and keep my usb cable in the truck for playing music. I only want to do so if I can find out what the dock is putting out. When I need juice I need it as quickly as possible.

If your only getting 500mA your phone will take hours to charge and then only if your not running wifi, Bluetooth or gps. Use any of those and plugging it in will just prolong discharge but not actually charge it. With just GPS running I pull over 700mA. I'm really tempted to put a female end with resistors (to fool the phone into thinking it’s on AC power or it'll never pull more than 500mA) on a split wire usb mini cable for charging at work.

I finally used my brain and checked my chargers. Here's the specs
Standard charger: 850mA
HD multimedia dock: 1.2A

I think the dock is rated higher to power the usb ports. I bet it still only feeds 500 to the phone for charging. Looks like its back to the cable for charging!

my wall charger is 850ma...

seems like till now there's no way to disable this

Just an update. I think the dock charges as fast as the wall power adapter. Almost certain.

This is interesting as I have issues getting my Atrix to charge in the car dock. I have the ATT boxed car dock with ecomoto dual USB. It simply will not charge in the dock. Connected direct to the car charger and it's super fast to charge. Maybe the ecomoto isn't capable of charging the phone in the car dock.

Is using a different wall charger harmful? I was using my old palm pre wall charger for the first few days and it is rated at 1000mA.

Nexus s battery recharge time

I was wandering if its only my nexus s(i9023) takes upto 3 to 4 hours to charge.
Sent from my Nexus S using XDA App

same here, up to 3-4 hours, which is quite much

The charge time is quite ridiculous
Sent from my Nexus S 4G using XDA Premium App

You can use a different charger - the one that comes with the Evo is 1.0A, not the 750ma that comes with the Nexus. Still - the Nexus is way too slow, but this helps.

I hope this is not the case. I just purchased the Nexsus S last night and i like guick charging while in the car. The iPhone 4 I have been using charges very quick. I am using a 2.1 AMP car charger. Right now I'm at 82% and charging so will see how long it takes to get 100%

Since my last post, battery has gone up 85% charged. I just disconnected to grab some lunch.

Check whether your phone is charging in AC mode or USB mode when charging with the car charger. If it is slow, I suspect it's charging in USB mode.

I have Galaxy Tab 7. Will that charge faster since the Tab has a bigger battery and hence a more powerful charger?

I believe the SGT 7 charger is a 5v charger, which is the same as the Nexsus S charger with 0.7A.

Buy a battery charger. I like the one from Samsung. There are also many aftermarket options.
So lovely to come home and pop in a fresh battery.

Might do that. Saw on eBay, 2 1500mah batteries and charger for 9.99. Only thing is they take forever to ship from Hong Kong.

Actually, i just took a look at my Galaxy Tab 7" charger and the output is 5V 2.0A. It's not the same amperage as the Nexus S, but higher. Should definitely charge faster then.

I use a 1 amp Pre cylinder charger.
No idea how long it takes; so far have only charged overnight with the occasional USB cable top-up.
Not sure if I'd try something pushing 2A though...

Nexus 7 Charger

Sorry if this sounds amateur, but I was wondering if I would be able to use my cell phone charger with the Nexus 7 without it causing damage. Or is the reverse true too?
The output on the Nexus 7 charger is : 5V - 2A
The output on the One S charger is: 5V - 1A
The input on the Nexus 7 charger is 100mA higher.
Now technically this means if I use the Cell charger the tablet would take longer to charge right?
But what if I use the tablet charger for my cell phone? Would it damage my phone?
I'm only wondering because I don't want to have too many cables cluttering my workspace.
Thanks in advance.

You're right about the charge time. And yes you can use it on your phone. I have a 2A charger for my g2x that's blazing fast.
Sent from my LG-P999 using xda app-developers app

It charges super slow on my GNex charger. 10% in an hour

you can use the nexus7 on your phone it will work as a rapid charge, i wouldnt make a habit of it...

Don't quote me on this, but using the 2A charger for your phone should work just fine, as it should have an internal limiter that prevents too much current from being passed through the device, damaging it. I have done that before (with a different charger) with success, so it should be just fine. Also, the N7 *should* charge on the 1A charger, just a LOT slower, and may only charge if you turn it off.

Thanks for all the quick responses guys. I just wanted to make sure I don't do any damage to them.

Charging problems

Is anyone else having problems charging their S4? I was using a 5V/1A car charger while on a trip and the phone was actually losing power faster than it was charging. I did have Waze open and was playing music using local files with Google Play, but my S3 was able to handle that fine and still charge in the car.
Additionally, I left it plugged in overnight for 6+ hours using the AC plug that came with the phone and it didn't charge up all the way.
Is there something wrong with my phone?
Sent from my SAMSUNG-SGH-I337 using xda app-developers app

I had the same problem in my car. I had a cheap car charger that was lower amperage than the standard wall charger. This phone is designed to charge with a 5V 2Amp charger. Your screen draws more power than your s3 so 1amp might be it's burn rate with screen on, GPS, music, etc.
I got a 2amp car charger from thinkgeek that works brilliantly. It was a little pricey. Amazon has one for 6 bucks. I highly recommend buying a coiled micro USB cable so it is more manageable.

Should be as safe as using the stock charger. Even if it was a lot more powerful than the stock charger it would still be fine because the phone itself is what regulates how much power to send the battery.

Pogo pins charging at higher rate.

Recently my wife broke her USB port on her n7, so I decided to just attach some wire to the pogo pins as I know there was a ground and a 5v line. After I installed battery monitor, hers was charging at 1000 to 1300ma. Mine charges at 500-600ma.
Maybe my port is broken too I'm not sure. Can anyone confirm this?

I also charge my nexus from a homemade dock at the 1000-1300 mark compared with my usb port. The usb port is so bad that most of the time I see it discharging while in use!!!
I believe this is a hardware fault as mine used to charge great through usb. at one point my usb socket stopped working altogether, I ran a soldering iron over it and it is at least working again, still slow to charge.
I have also been following a thread about this in the google user forums. One person stated that when they changed the usb board charging rates resumed to normal standards. There is a lot of people in that thread suffering from this. Bad show google.

Have you guys confirmed that the n7 charges faster off the pogo pins?
Sent from my SAMSUNG-SM-N900A using xda app-developers app

It can charge just as fast off USB I know mine does I think the problem seems to be that the ports are easily damaged and it slows the charge rate

I have been following a thread on google forums about people suffering from poor charging rates. I can confirm that many users in that thread, myself included, have found that charging through pogo pins charges normally, whilst the usb charging takes forever and even discharges with screen on!!

is that with the provided 2 amp charger?

It is with a third party charger as my charger broke, but it was the same with the original.
Sent from my Nexus 7 using Tapatalk 2

The 5V oem charger output 2000mA. Any charger 2A should fast charge.
Also the pogo pin can charge on 12V 500ma (which is automobile acc. standart)
See more info on Qualcomm FastCharge Standart
There's a chip that identify the power output available. So a charger 1A charger will be identify by the device, therefore it won't fastcharge.
