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

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

[Q] Wind up/Dynamo charger

Does anyone know a wind up/dynamo charger that works for HD2?
I found quite a few such chargers on ebay, but without any output voltage/current specifications.
Thanks!

Do you have any link ?
What about charging time, turning the dynamo....all night long for a two minutes call ;-)
Outpout should be 5 V / 1000 mAh
Input is muscles !

The 1st one has 5.5V and 600mAh, while the others don't have specs.

wish ebay got some tiny urls...meh i think they would do for emergency...nothing else. manage to get 1 or 2% after 5 mins of hand work

Not for the HD2 but i bought one for my diamond. I found it actually discharged the battery! Winding the handle the diamond displayed that it was charging and i could feel the rotational load increase as the phone started drawing current. However after 5 mins of winding my phone was 1-2% less than before 'charging'!

The same result! I was miffed. I thought that maybe the charging circuitry takes some of the power to operate and that the charger wasn't even providing enough for this, therefore it was drawing the rest of the battery and in turn depleting rather than charging the battery. I'm not sure why this was just my guess (and i'm an electrician )

well guess that answers op's thread
i remember when i was in school for a construction project my class mate was making a wind electricity fan from wood with a dynamo stuck on the tri wing when we tested how much power it produced when spinning it as hard as we could it was producing - power couldn't even light a bulb to show its working haha
guess the same **** here...just probably not going fast enough to power it properly or u want to be superman

Well, I thought about getting a solar charger, but I want something that will charge my cell anytime and not only during daytime or sunshine.
Although, if I don't find a wind up charger, I might end up getting a solar.
So, which one do you suggest? Have you tried it?

there are some solar chargers that can keep the charge in its battery, so even u don't have sun, u can charge it later.
i tend to buy this:

which is quite cheaper ($6.14) and has the proper specs (5.5V, 1000mAh) for HD2.

I bought a spare battery & USB charger (Ebay; never had any regrets), as I do with all my earlier smartphones. USB cab be from car, computer, photovoltaic panel or mains unit.

Thanks for the info, but the price is quite high...

Another useless gadget
Well, slightly offtopic, but the thread was the closest I could find to post the following.
Recently i bought a wind-charger while on vacation in Paris (a charger that uses wind power while you bike for example to charge itself and then you can charge different devices with it).
And here is my negative review for it:
Well, i was very excited to buy this gadget (costed me 30 EUR). I bike a lot and this was also meant to be used for outdoor hiking activities.
But..
First of all the lack of any type of power meter renders the device unreliable to the point of uselessness. You take the charger outdoors (with a 1200 mAh battery inside) and you have no idea how much of the battery is filled(unless you pre-charge it from mains). But then, if i needed just an external battery, there are definitely better and smaller choices.
Second: You cannot pre-charge the charger from mains and charge the phone simultaneously, nor you can charge your device "on the go"-directly from wind..
Third: You cannot turn on the quite weak led lights in front of the device and charge it simultaneously (so, for example if you bike in the evenings when it is late, you have to chose, either you use it's light for safety, or you charge the device. Ridiculous)
Forth: in the description on Uniross site it is said "Can also be charged through a computer or through wall plug". Well, it can be only charged using supplied wall plug, no wire for computer charging..
Fifth: When fully charged from mains it will charge my discharged HD2 only to 60%, which means that it is less then 60% effective in transferring the charge. Also make sure your device will agree on some 500 mA of charging current (most of them will probably)
Sixth: It does need quite strong wind to charge, it starts to charge when your speed (in no wind condition) gets around 15 km/h. People say it needs some 15 km of ride to be fully charged. How they managed to estimate that the charger is fully charged - i have no idea.
Seventh: The charging indicator (which tells you that the speed is enough for charging), is placed right in front of the charger, so to check whether it charges you have to dangerously lean forward or ask the approaching bikers if they see a green LED light- truly stupid design flaw.
Eighth (the most annoying and stupid): YOU HAVE TO CHARGE IT FROM MAINS FOR SOME 20% BEFORE YOU CAN START CHARGING IT FROM WIND!! Can you imagine how dumb this condition is.. first - there is no way to know how long should i charge it from mains to get the necessary minimum 20%. Then, when i am outdoor and lets say charging the phone - if i use all the juice - the charger will become useless, as there won't be a possibility for another startup charging. Then I have to charge till it is decreased to 20% and use the wind to charge it back. HA! there is now way to know that it is on 20%,10% or 30%... how dumb the design and functioning can be... This is truly a raw device they let out on market. Shame for Uniross.
(i will stop here because it is too late...)
I wish i would have read a review like this before i went and got this piece of ... something... Hope it helps someone else.
Attached is the picture of mine in packaging

Nexus S Replacement Battery 1500 mAh with charger

Nexus S is a great smart phone, however, like all other touch screen smart phones, the battery of the phone runs out within a day of usage. And if you do not have a charger or the time to charge the phone in the middle of a journey or in office, you surely run out of luck.
Fret not, because there is the Nexus S replacement battery (1500mAh) that can come to the rescue. This 1500 mAh battery comes with a USB/AC charging cradle that can be plugged to the power outlet. All you need to do is to insert the battery in the charger, plug it to the power outlet and done. Once the battery is charged, you can use it with the phone.
Since this is a replacement battery, it does not come with the Samsung branding. However, the battery looks identical to the stock one.
Besides charging the replacement battery, the AC charging cradle can also charge the battery in the Nexus S phone. Thus, you can charge two batteries at one go. Once in charging mode, the USB/AC cradle displays blue light.
I used the battery with our Nexus S phone and were quite impressed with its juice. The battery almost lasted for a day with use of phone, 3G and music playback. And this replacement battery surely makes sense with 3G services now live your phone will be more hungry.
Available from dealextreme.com for just $8.30 (Rs.370) with free shipping, you can buy one yourself by visiting the product page here.
Specifications
Specifications:Battery charger input: AC100~240V 50/60Hz 0.15A
- Battery charger output: DC4.2V~350mA~±50mA, USBC5.2V 800mA
- Battery charger with 2-flat pin plug
- 3.7V/1500mAh Li-ion battery included

I'm skeptical about generic "made in China" stuff. But thanks for the review.

I have the same exact battery wall charger, it broke in about a week or two. The pins that touch the battery somehow snapped off. I would'nt recommend it

[REVIEW] Samsung Note 2 Stand and Spare Battery Charger (3100mAh Battery Included)

I have bought this item: http://www.amazon.com/Samsung-Battery-Charger-3100mAh-Included/dp/B009M5J9HY/ref=sr_1_3?s=wireless&ie=UTF8&qid=1369030345&sr=1-3&keywords=note+2+charger
I am really disappointed with this. First, I thought the unit was defective, since I was completely unable to charge either my original battery or the one that came with the charger (battery EB595675LU, with Chinese writings added to the language list). I tried different cables and wall sockets and got nothing. The unit does have one LED light, but it never came on. Eventually, I noticed that it would actually work if I shoved the USB cable in really tight. I also learned that a 0.000001-inch move would disconnect the power, even if the cable was still physically connected to the charger. Keep in mind that this happened straight out of the box on the day it arrived. It was brand new.
After discovering that the charger could not be moved at all or it would not charge the battery, I was able to charge the battery that came with it (EB595675LU). It charged OK, but I felt it had less power than the original battery. It drained much faster than the original battery, even when I was home with Wifi on instead of LTE. I think that happened for one of two reasons: (1) the charger didn't completely charge the battery, or (2) the battery is indeed crappy/fake/less powerful than the original one.
At this point, I'm unhappy with the quality of the product. It's brand new and I already have to deal with the problem of the cable moving and disconnecting the power. If this charger is really from Samsung, this quality is unacceptable. That's terrible. But wait! There's more! I used the second battery until it died and tried to charge it in my phone. No problems there, but the charger completely died. Yes, died as in completely dead. And I've charged one single battery on this thing! Now nothing was working. Original battery, second battery, nothing. It just gave out on me. I looked at the battery contacts and noticed that one of them was not aligned with the other two. I touched the crooked one a little bit and it started working again, but still gave me the USB cable problem (disconnecting power). The crooked contact is still crooked as I didn't want to force it and risk breaking the damn thing.
I wanted to buy this charger and the extra battery because I'll be going on a trip soon and didn't want the extra weight and thickness of an extended battery. I chose to get a second standard battery and a separate charger, so I could just swap batteries on the go if needed. I really hope the unit I got is defective. I can't believe Samsung would put out such a crappy product and expect it to sell. I definitely don't want to be in the middle of nowhere on my trip and find out the stupid charger gave out on me at night and my second battery didn't charge. And what's worse is that just about every separate charger I found on eBay/Amazon has terrible reviews due to quality issues.
My goal is to have a reliable/trustworthy separate charger and a second standard battery. I'll be able to maintain my phone's thin profile, have enough power to take lots of pictures, and have no charge downtime other than overnight. Power banks and extended batteries wouldn't work for me in this case. I hope this review has been helpful.

I have the official Samsung battery & charger stand. Bought mine directly from Samsung using a 50% off code from registering the phone. Works as it should and can be moved around. Only cost 20 bucks, too(50% off)
Sounds like yours might be a knock off. Send it back & get a refund. If you need a 50% off code, pm me.

Samsung Wireless Charging Pack Review

Hi Guys,
This is going to be my first review. figured it might help some people decide whether to buy Samsungs Wireless Charging Pack. For those in the Philippines, i got mine at the samsung official store in SM Aura, BGC Taguig
Just got it a few hours ago so this will just be my initial review with photos, ill give a whole day of use review tomorrow when ive had the chance to use it fully.
Findings:
1.) The case is huge, actual measurement with the phone in is 1.8cm or 0.7 inches. It really feels like a brick
2.) It makes the phone heavy. I dont have a way to measure it exactly but an estimate would be a can of coke (the drink).
3.) its not "Fast Charging" feels like the speed of a normal wireless charger, about an hour for 25%. but then its a phone case with a battery so its not much of a bother since there are no cables.
4.) Wireless charging doesnt work with the case on. the case will charge your phone wirelessly, but if you put it on top of your "desk/normal wireless charger" with the case on, it wont charge your phone. case is too thick
5.) not sure if this is safe or if it might damage the phone, but if i plug the case to charge with the phone attached to it, it charges both. the case charges and it charges the phone wirelessly at the same time.
6.) as can be seen on the photo, there is no "over lap" or "lip" when the phone is in the case. if your phone drops screen first, there is no protection
so basically thats all i can say for now. Tom ill try to see if it can charge the phone to full from empty with one charge.
Im a heavy phone user, the note 5 if unplugged at 7am only lasts me till 2pm. so this will help alot. i can deal with the increased size and weight as long as my phone makes it to bedtime.
let me know if you have any questions, ill try to answer them.

thanks for posting pics... been looking for this device.

Where did you get it? I have been looking for this.

How efficient is wireless charging? for example, if the battery pack is 3400MAH and the internal battery is 3000, can the pack charge the phone from 0 and still have some left over? or does it only manage 1 full charge (a waste of 400MAH) or can it only charge up to 90%... etc.

I got it from an Official Samsung store here in the Philippines.

Cant answer this right now because i think i got a faulty unit. Ill return for an exchage over the weekend. Its only able to charge my phone from 10% - 50% before the battery pack goes empty.

Yikes, I hope the replacement one charges better than that.
Sent from my SAMSUNG-SM-N920A using Tapatalk

I've been thinking on this and I almost think it would be better to have a separate battery that includes a Qi pad, as opposed to one built into the case.
Built into the case, you always have to tote it around when it might not be useful to you.
you can't use any other case
you couldn't opt for a wired connection, assuming that wired is more energy efficient than wireless.
I'm all about convergence and efficiency, but this doesn't seem to be as beneficial as it ought to be.
In my opinion, a separate battery pack with a qi receiver and fast charger, so it could charge on your pad (or cable) , and then put your phone on top of that, so the phone could charge at the same time as the batter pack.
------ Phone in its case ----------
------ Spare battery ------------
------ Qi Fast charger -----------
The have a magnetic connection between the phone in your own case and the battery pack, so for those that keep their phone loose in a purse or bag or pocket could use it without cables or straps keeping them together.

Php 3,200.00

So did you get the replacement? Any different results on the charge %?

Hi. Yes i did get a replacement. Seems to charge faster also. Well 3 hours from 0 - 80. Im guessing it might be able to charge up to 100% but i use the phone while its charging which could account for the 20%.

I find myself using the fast charging battery pack more. Maybe its just personal preference. But the "wireless pack case" is just too heavy and takes too long to charge that its become cumbersome. While the fast charger battery pack only takes an hour and its done charging
