I have seen them on ebay, to me they look like the kind of thing you would use to charge a second battery if you had one.

Yep it is. Just wondering if anyone had tried it.
Looks like a generic charger which you set the size to fit your phone's battery

I just purchased one. I had to buy it as i am in need of a charging cable (lost mine). If anyone has a spare charging cable i would gladly pay it as long as they will ship it registered mail to canada
in the meantime does anyone know what pins are postive and negative on the battery?

Chargers off Ebay
I got one off Ebay and it is working but it is extremely slow! It is a MyBat brand and you see tons of videos on you tube, but it is taking almost 48 hours to charge it to 100%. Can anyone confirm this 3G brand is any faster? Or can someone who has an Ebay account buy one and list a charger cable lol, I use mine for two to three days then I have to charge it two days. Please help and any input would be greatly appreciated!

I would like to know too, which pins are postive(+) and negative(-) on the battery contact?
does any one can help me to do a test on the battery??
thank you vvvvvery much~~~~

Email from seller
Hi guys,
I bought the same charger and asked which one of the two metal prongs is positive and which one is negative and if the seller knows which contact on the battery is positive/negative.
Apparently the charger can automatically switch polarity...
I've also noticed on the label that the charger has 600mA through the USB port and 400mA through the mains. That's why it's really slow I reckon...
Anyway, here's their response:
You can use the charger by following instruction:
Features and Functions Guide of the charger
for Dell Streak
Standard of the electrical
? Electric current of import: 110V-220V 50/60 HZ 0.1A
? Electric potential of battery charger: 4.2V-5.0V
? Electric current of battery charger:400MA
? Electric potential and current of USB charger: 5.0V-5.2V 600MA
Instruction
? The contacts of the charger can move, you can charge many different styles of battery according to the contacts of the battery.
? You also can adjust the length of the charger according to your battery, the maximum length is 2.95 inch, the minimum length is 0.67 inch. But you should do it gently, or the charge will be damaged.
? The battery for Motorola Droid A855 has 4 contacts, you should use the outsider contacts. And the charger can adjust Polarity automatically in order to fit for the polarity of the battery.
? When the charger is working, the light is pink, when the charger finishes charging, the light turns into blue. And the battery can not be charged for a long time, please pay attention to the light.
? The battery should charge the battery for 10-14 hours in the first three times, and later you should charge the battery for more than 8 hours. Then you can activate the capacity of the battery.
? The USB charger can charge your phone with a suitable USB cable. When you use the battery charger and the USB charger at the same time, the charger will let the USB charger first. The light is blue, after the USB charger finishes its charge, the battery charger will work, and the light is pink.
Warning
? Please do not take out the battery when the charger connects to power supply, or, you will hurt yourself, the battery will be damaged.
? Please do not knock down the item on purpose.

Thanks mate. So have you had any success in charging with your charger?

Its slow but it works. Took about 30hours to charge my battery.
Its only 400mA. 1000mA is preference when charging our batteries.

Yes, it seems to work fine, although so far I have only used it on a partly charged (~80%) battery.
The charger that I received works off the mains (110-250V at 50 or 60Hz).
It delivers 4.2V at 350mA (+/-50mA) to the battery. However, the battery is under no load, whereas when you charge a battery in situ in the Dell Streak there will be a drain on the battery while it's charging (depending on whether the display/GPS/wifi etc is switched on).
The charger also has a USB output (5.2V at 800mA).
Given the price, I would expect all the voltages and currents to be nominal (although to be fair the build quality is good enough).

Hi I just bought the 3G commerce one the one on ebay but got it at a local chinese/electronic store, the plate that is used to hold the battery against the two pins has to be stretched almost all the way out, feels like it will break the inner spring, probably wont at least I hope so. I have yet to charge my battery with this charger but will do it tonight and see how that goes.
I usually charge my battery with a blackberry desktop charger I had to mod the hell out of it so it could fit the streak battery, and that charger i believe is 4.2v 350ma and charges the battery from 2% to 100% in a little less than 4.5 hours. We use 110v AC for main juice.
When using this "generic" chargers ALWAYS make sure it is a Li-Ion/Poly charger.
You can start a fire if you don't use a proper charger. I will point this out as much as possible

Streak car charger

Just got a griffin powerjolt micro, comes with an ipod cable so you'll have to use your own, but it charges the streak up a treat
Think it was 12 pounds from amazon.
It's designed for iPads, which need 2 amps, it's rated for 2.1 amps. Charged from 30 to 60% in 20 mins while using gps.
Hope that's useful .
Sent from my Dell Streak using XDA App

For battery life is better to charge with low amps and for a long time. I would prefer ,not to use a charger with more than 1A

i got myself te belkin 1A charger. Should work good I guess.

As mentioned in the other thread, both these two work just fine :

https://www.dealextreme.com/p/car-cigarette-powered-1000ma-usb-adapter-charger-black-dc-12v-40470
$6 or $2 including free shipping worldwide. You'll need the Streak's USB cable to connect it.

The car charger does not force power into the phone, the phone draws what it needs. Using a power supply with a higher Amp rating means less strain on the charger not more power than is needed going into the phone.

Sorry for my bad English, I guess you do not understand what I mean.
You're right that the car charger with more amps does not force more power into the phone (I do not say that),but if you use a charger with more amps , charging time is less. The battery prefers long time charging with less charging amps. In fact using less charging amps ,the battery allowed to load more power (a little bit ). You can try it by using a USB port of yours computer to charge the battery.

Maybe it's just me, but what you are saying is exactly the same thing.
If the charger isn't forcing more power into the phone, then the charging time will not change. If the battery is receiving less current then what it was designed, such as a low powered USB port, then it would take longer then normal to fully charge. But once the charger puts out the amount of current that the battery will normally draw, the battery will only charge at that rate. Increasing the current beyond that amount will not speed up the charging time or push more current to the battery.

Anbuch is trying to say that the battery will last longer in the first scenario - the longer, slower charge from the low powered USB port.
Quicker battery charging does degrade the cells in less time - if you were to always use a 500mA charger, you would get more life from the battery than if you were to always use the stock 1000mA charger.
You can pick up a replacement battery from eBay for $10, so none of this really matters - when your battery wears out in 18 months, just buy a new one.

Nomgle ,thanks, this is exactly what I wanted to say!
I just gave an example with a USB port. In fact a USB port and a stock 1000mA charger are save enough for the battery of a Streak (1530mA). I just wanted to say : Do not use 2100 mA charger

This will "kill" the battery very soon

Some battery reading:
Understanding lithium-ion
Charging lithium-ion batteries
How to prolong lithium-based batteries
From the last page linked:
[FONT=Arial, Helvetica, sans-serif]Generally speaking, batteries live longer if treated in a gentle manner. High charge voltages, excessive charge rate and extreme load conditions will have a negative effect and shorten the battery life. This also applies to high current rate lithium-ion batteries.
Not only is it better to charge lithium-ion battery at a slower charge rate, high discharge rates also contribute the extra wear and tear.[/FONT]

It was for my friend`s Galaxy Note 3 , he does not have the phone any more but I will find the charger and pm you for the model

The phone can handle it but the 1a is the suggested and anything more can damage the hardware. I have a rapid charger that will charge my battery to full in about 30 min from 0. It works on the stock kernel so it is not a custom kernel option. And the fast charge is a pc USB setting if you read the discripition.

Really? I've always heard that the phone knows only to pull 1A from the available amperage. I've always heard that using something less than 1a can damage the cord and possibly the charger itself.
Also: Using fast charge can seriously degrade your battery over time. Better to only use it when in a pinch.

That's why I said it can damage the device. Mine is a stand alone charger so no damage to the cord.
I only use it when I really need to. Like when I have kill the battery as well as the Mophie pack and am in the middle of nowhere and need to make a fast call.

I see what you are saying. I read it differently earlier for some reason. Actually: I know the reason. I've been severely sleep deprived the past several months and have been experiencing sleep paralysis the last several months two or three times per week.

Wrong So Wrong
Fact with stock kernel htc one m7 charges nearly 20 mins quicker
there are pro's and cons to this unless used at the right time in the right situation
sick of people saying it will harm it or that it is there to use only 1a
first of all the stock charger allows 500ma of charging and 500ma for the phones consumption whilst charging
when turned off it should only charge at 700ma
a flaw that was left on purpose by htc for monetary gain
holding fast charge and even full charge capabilities back widens the gap between the m7 and the m8
making people want to buy the m8 charger or better the m8
here's why and how they hold it back on it's full speed charging with !!!!!!!the stock HTC charger
Here is the explanation
The best way I have ever heard it put is like this
Where current is water
Imagine a water barrel that is being filled up at a rate of 1 liter an hour
The barrel has a over flow pipe aka battery if this pipe is only wide enough for half a liter an hour and you turn the tap filling the barrel to 10 liter an hour how much is the over flow receiving still half a liter.
So here is the big if and but
If you are using a 2.1a 5.1v ipad charger
Whilst gaming you have the CPU GPU and battery making heat and thus degrading Battery life and performance
If you turn the m7 off or have all apps closed and phone idle then this is far better than gaming with the stock m7 charger
as heat is the NO1. killer for battery depletion
As for comments about voltage of other chargers are irrelevant as the circuit in the phone limits voltage with a simple I/0 circuit if voltage is either under or over pre set parameters it will do nothing as it won't allow any flow of current at all
Unless lots bigger (BANG)
How is the current limited
Self explanatory as the charger states what it is built to supply
Conclusion is simple amps are limited by the charger plug or USB port
Voltage is not limited but safe gaurded by the phone so if your phone registers a charge with a 5.3v plug then it is fine as long as you use it sensibly
Apps are highly unreliable as they are a close prediction at best
And don't correctly include what is used by the phone
Also some current will be being stored all the time in capacitors
Fact the m7 charges quicker with higher ampage application measuring ampage will not be accurate.
The only accurate way is to time it from empty turned off
And blind people who say HTC know best do not understand the workings of any multinational corporation
By holding the fast charge back widens the gap between the m7 and m8 meaning more people will go and buy the m8 fast charger or even better the m8

Fast charge & USB

Hi everyone, I'm looking for more info about the fast charge function of the Note 4: I can read on the charger that it either provides 5 on 9V. Does this mean that I can supply 9V on the USB port to fast charge my note 4 ? Does anyone know how the charger detects wheher it it should supply 5 or 9V?

Yes, it means that that charger will deliver power at 9 V (at 1.67 A) to the phone.
As for how it decides which voltage/current to use, it'll be as a function of the battery's charge level, temperature, and probably some other factors, but that's getting into some very specific settings for the phone/charger system by that point.

thanks for the quick reply! I've got a couple of Dc Converters (buck) and lipo batteries (11.1V) and was wondering how the phone signals the charger it can accept 9V and if I can use my DC step down to feed the phone with9V...
I guess I will have to try

I agree that it might be damaging to the battery (but obviously not extremely damaging). Why else would there be the option to switch off fast charging? I've switched mine off anyway because I have no use for it as my phone charges overnight and makes no difference how quickly it gets to 100%.

I personally thought the option to disable Fast Charging was Samsungs' way of reminding us, or letting the uninformed know, that it can do it.

The generally accepted rule amongst radio control hobbyists is that provided the battery is well made, it's not the current that'll kill a battery - it's overcharging it (over 4.2V per cell on a LiPo). Provided that the charging circuit is good (and I have no doubt it is of a high quality) we shouldn't see any degradation in battery life when used with the fast charge process.
Others may chime in with more info, but that's how I understand it.

l believe the fast charge is safe for the battery as it charges it at 1C (=1hr charge) which is actually not so fast.
Here is my tip: I have an old charger to charge overnight and use the mote 4 charger only for fast charging during the day (I leave it in my bag). I'm actually lookingfor a way to make a fast charging battery bank.
So here is my question again: has anyone tried supplying 9V to the phone ?

best device in charging
its charging up the whole battery in about an hour, i really like that and the battery gives me a full day

So far right now i can talk for about an hour and play games for about an hour and leave it on overnight and all day and still have 82% left. I'm super impressed!

YOAH!!! Thats insane!

I know that the amperage on the charger is huge in its speed.
I used many custom Roms and kernels in the past on other phones with fast charge. I used several chargers and always charged much quicker with higher amperage outputs. Some were as low as 300 MA to as high as 1.2A. This is why the amperage is so high on this phones charger. The voltage is needed to push the charge quicker. Good luck finding high A charger at 9v.
My 1.2A charger i use as backup is much faster then the 500/700ma ones I have but they are all 5v and can't compete with fast charge.
Sent from my *ROOTED* Note 4 SM-N910W8

I'm also looking for a power bank that would be able to charge at
- 5V 2A,
- 5.5V (Galaxy Tab S)
- 9V (Note 4).
- with 2x18650
- able to charge itself fast too;
- charge-through (charging a device while changing itself).
i now have this ENB model, but it does not deliver 2A to Tab S (and charges at 5V not 5.5).
And it charges itself with 1A even from 2A-capable power supply.

Hi all,
I notice something that the note 4 does not charge fast after I installed S-View cover (original one), although an indication appeared that it is using the fast charging function.
I guessed it assume that the cover is open and charge slower. However, if I removed the S-View it charge noticeably faster.
Do you think this a bug in firmware ??
Thank you,

The so-called USB fast chargers query the device to be charged. Devices capable of fast charging at 9V DC have additional circuitry in their USB ports that the charger can detect. If the charger doesn't detect the circuitry, it falls back to 5V DC mode, like any other USB charger. Assuming the fast charger is functioning correctly, it should not over-charge an older phone or tablet that doesn't support fast charging; it will simply take as long as the original "dumb" USB charger did.

Any charger that has Qualcomm QuickCharge 2 built in.
They are a little bit more expensive, but are worth it in my eyes.
They charge a lot quicker than normal chargers as the charger monitors battery temp and delivers maximum charge without stressing the battery.
I can charge my phone from under 10% to charged in 2 hours and it's not even warm.
When I plug the phone into my PC at work it gets really hot and I'm sure that's not good for the battery.

It CAN be charged by any QC 2.0 charger but you won't get any out-of-the-box. The standard charger is EP880 paired together with EC803 charging/data cable. My original charger stopped working after just 10 months and now I'm using Blitzwolf BW-S2QC charger.
But it's true - quickcharging a phone does not even make it hot or anything like that. Unless you start using it but it's my case
I recommend buying QC 2.0 charger.

Be sure the cable you are using supports quick charge 2.0 as well
