power saving battery charger:
I want to buy this battery charger,
because I've buyed my HD2 from GB (I live in Germany)
and the plug doesn't fit
But I have some doubt about the specs:
ORG: 5V, 1000 mA
this: 5V, 1200 mA
will this make problems?
Sure this would be fine!
Should work fine. If it doesn't fit try finding an adapter. They aren't expensive these days.
Doesn't it matter what the power output is for the charger? The mah rating, or anything or are you guys just saying that any charger with a micro usb on the end will work and that the phone itself will regular the power?
Your phone needs 1000mA minimum, 1200mA is 20% better It will work very well with your HD2. If you don't like it, pass it on please, I'll take it off your hands

That's not correct, you shouldn't really be going over 1000mA, I got a micro usb charger off eBay for 1.75GBP and its rating is 650mA and it works fine.
So you can safely charge your phone with a 700 mah rating, and it will just charge slowly but will not negatively affect the battery life longevity or harm the phone correct?
One person said it has to be a minimum of 1000 mah, so that makes me worried of going below and using a 500 mah and having my battery get screwed up, or the unit blow up.

Used my cheap ebay USB wall charger rated 500 mAh... worked for a week, now it's dead..just wouldn't charge anymore. Good thing the charger didn't blow up..lol

You can go below with no problems but there will be a minimum amount the phone will need to charge. My post above was incorrect about the charger i got, its 550Mah not 650Mah and still going strong. When purchasing chargers off Ebay i always buy from my home country, that way if anything untoward goes wrong i can go knocking on their door!
on chargers
what u guys should watch out for is the voltage not maH. 5V is what we need to pay attention to. If you use a higher voltage the battery will explode.
The difference between 550 mAH or 1200 mAH is the charging time. With 1200mAH your phone will charge quicker vs the 550mAH. Just think of it that you are trying to fill a pail with water. 550mAH is like using a small straw. 1200 mAH is like using a big pipe.
Hope this helps

This has been the most useful post in this thread thanks....
So, I have a Motorola charger for my BT headset that is rated 5V and 550mAH... I assume I can charge my phone with this safely without any adverse effect on the battery (just a slower charge)?
Makes sense as I think charging VIA usb cable and a laptop also takes longer... This would be great as I have a few of those motorola chargers lying around and won't mind using them for bedside overnight charging... it will free up another micro USB cable for me
I am assuming it will be ok cause USB charging from laptops/computers are about 4.7V at 500mah.... This means this little charger should be ok I think... I have ALWAYS left my phones connected for long periods of time to laptops/PCs... does not seem to affect battery lifespan. Can anyone confirm this or tell me differently?
im the "drop out"
yep looks like im the "drop out" i got coming from HK its only 350mA and even befor it arrive i look for another.
I see espansys have one 1500ma AC Adaptor but very expensive > but i suppose if want battery to last > good to get
So, I used my Motorola charger for my HX1 bluetooth headset to charge my phone overnight (with phone on). The only thing running was SPB time with an animated background.... The charger is rated 5V 550Mah..... all seemed to be fine at the begining.
However, this morning, I work up to a blank screen and the fully charged LED on. Even after unplugging, the LED stayed on and the phone was unresponsive. I had to remove the cover and pull out the battery to restart. I am wondering if it was the charger or perhaps SPB time? I will give it another go tonight without SPB Time v3.1.1 running to see if it does the same. I hope Im not destroying my battery!
Edit: I charged it last night from 5% till full with no SPB time running... no problems cool!

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.
Sent from my Dell Streak using XDA App
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.
? Please do not let the charger be damped or be exposed in the water.
? Please do not drop the item form a high place.

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
solar charger / dell streak / recharger / battery
why not use a solar charger, i bought one from here ( i am not making an ad, just saying what has worked for me for your sake)
apparently i cant post links yet, just go to gkitshop, look up a 2600mAH solar charger
have a good life
I had a thought today about these "extended" batteries like the Andida that are supposedly rated at 1600 mA or larger.
What if it is not that the battery won't hold more charge, but that the chargers are limiting the battery to the same capacity as the OEM battery?
I mention this because I have three batteries, two Andida 1600, and my OEM. All three of them register at 12296 mA when fully charged. This is when charged via my external charger or charged by plugging in the serial port.
All of the external chargers are made for a specific model, what if they are programmed to stop charging at a specific mA?
Can someone with the Mugen and NRG ROM tell me what mA is listed in tBattery (tools folder) with a full charge?
Yeah i was thinking of this too... i would like to try a direct battery charger,like the chinese one where you have to move the pins to meet the battery contacts and an andida battery...Maybe with those universal battery charger we can go over the 1200mah of the original one

I HAVE a Chinese charger, although one does not have to bend any pins. But it was made for the HD2, and these things have circuitry inside them to prevent over charging. I just don't know if the same circuits are stopping the charger at the "normal" charge level.

For Li-ion and NiMH batteries, once battery is close to fully charged the the charging voltage decreases, which indicates to an intelligent charger that the battery is fully charged.
So basically the charger has no data regarding battery Mah size, the charger keeps inputting until it registers a specific change in input voltage drop.
All the standard sized batteries listed as 1600Mah are fake, end of story. tbattery ain't the one lying.

Thanks for the explanation. So the electronics for overvoltage protection are in the battery?
RE: 1600 batteries. Well, they do make adequate replacements for the standard OEM battery, but yes, they do not reach their advertised capacities.
Overcharge is monitored via battery temp sensor & bat has protection circuit.
Andida 1600mah is ok as standard replacement but they will not last as many charge cycles as a quality brand replacement or OEM bat.
I see this solar powered battery charger on dealextreme, but are there any other better options? Like waterproof or made more specifically for our IncS with micro-usb.

Hi, how is this charger ?.. How long it takes to charge the Incredible S and what is it's standby time ??
Is it really worth the price ?

i dont use it as my daily driver.. just in case of emergency.. but it charges pretty fast and it charges till 40-50%... right now its kept in some corner... but i charge it through usb rarely use solar...
all the solar chargers i found so far only charge with an output of 80mAh, so once the battery pack is empty its actually useless.
i think its better to buy a batterypack without the solar charger because it wont be much help.
I think solar charger cannot give enough voltage for phone. I think it just an option to make your phone battery not drain out.
just buy one of those powerbanks, relatively cheap and charge as fast as a wall adapter.
i dont think the solar charger is necessery for common user

Voltage isn't the issue. You'd just use a boost converter to bump it up to 5V. Every battery pack like the powerbank and similar includes such a circuit, as they either use a 3.7V li-ion (or li-poly, or similar) or a pair of alkalines (1.5Vx2).
The issue is getting enough current to charge something meaningfully.
Hi
I wish to know if i plug this charger in my pc with an usb cable, could it charge an external battery or the usb is only for charge the phone when it's on the wall charge ? I don't want to put it in the wall. I wanna charge my battery in plug to usb pc.
Is it possible ?

Sorry, I didn't quite understand the question, but from the link you provided - that's a wall charger where you can either plugin a battery directly or attach USB cable to connect your phone for charging.
I would not recommend using usb ports from your PC or laptop because they typically output very low current, close to 350 mA and it will take you a VERY LONG time to charge a phone or external battery, etc.
Hi.
I would like to find some thing to charge my anker 3100mah and my stock samsung battery with usb port from my PC, not with wall charge even if it take long time because i will put it on the night or maybe all the day (about 8 or 10h)
I will use one while the other will be in charge on the usb port

oh, I see. You can use one of the chargers from my other review: http://forum.xda-developers.com/showthread.php?t=2249269 or use this charger: http://www.ebay.com/itm/USB-Desktop...25687?pt=Battery_Chargers&hash=item564ff1abd7
I see now that you want it to be plugged into your PC rather than wall. So you need DC charger, not AC charger. Those 2 above will do what you are looking for.
Thank you very much !

This has a 700mAh wall charger. But does have an USB cable. Will charge much slower on the low amps of computer USB ports. Does come with battery.

No worry like i said before, i just put in charge all the night or all the day in order to switch every day or night. It may take 8 or 10h, i don't really care because i switch with the other battery which can hold the day while the other is in charge.
And i don't want to overcharge by wall charge, the less mA there are, the less i damage the battery with long charge no ?
You are being just so silly. Just use a longer cord. That will solve the problem. Don't be like one of those crazy ladies that as to have it this or that way for some nonsense reasons, like home fashion, that is just the way it was setup, the cluttered look from the cord would drive me crazy, or something else like that.
There is circuitry that protects the batteries from overcharging. So don't worry about overcharging the batteries.
In fact the more that you keep the batteries charged the longer the batteries will last. The batteries lifespan is about the amount of full charge cycles. Say the battery is still 75% charged then you start charging to 100% (that is 25% total charging). That is not a full charge cycle. That is only 25% of a full charge cycle. Say the next time the battery shows only 25% charged this time. Then you charged again to 100% (that is 75% total charging). 25+75=100 The total of the two charges equal to 1 full charge cycle. As you see, if you keep the batteries charged then the batteries will lasts longer.
All batteries also have a shelf lifespan. That has nothing to do with charging or not charging the batteries. That has to do with the lifespan of the materials of the battery. This is completely different from charging practices to keep the battery good for longer periods of time.
Modern high end rechargeable batteries now days are much different from rechargeable batteries of the past. So past best practices don't apply for today's high end rechargeable batteries.
What you are doing is the worst practices for your batteries.
The more & quicker the charging of the batteries and the more that you keep the batteries on the charger the longer you are going to keep the batteries good.
The slower the charging the more battery power may be in use to keep device or charger running. Not good at all, because that is eating into the full charging cycles that the battery has in its lifespan.
With your method 75% total charge can take another 25% of the full charge cycle just as power leakage in keeping the device or battery charger going. I told you that it takes at least 700 mAh (this is by Samsung's information on the charger alone) just to guarantee to prevent this kind of power leakage. A computer's USB port (500 mAh at most) will have much less amps than that (depend on what else is on that same USB bus line (motherboards shares some USB ports on a single bus line) (this can mean much less than 500 mAh realistically). It is guarantee that you have power leakage.Which means that your method shortens your battery's lifespan.
