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:

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

Battery Accessory with MicroUSB Tip

Hey everyone... I just picked up a neat little battery accessory at BestBuy (Canada).
It has small battery pack and then extra USB tips. It has tip for iPod, MiniUSB and MicroUSB. It also has a retractable cable.
http://www.bestbuy.ca/en-CA/product...spx?path=7952c481ffdbd62b6ec06e2879027741en02
Hope you find this useful. Oh and it was on sale ! $29.99 at Best Buy Canada.
Here is a link to the MFG website.... http://www.diamondmm.com/DP1800.php
And for those in the USA, here is a link to Amazon.com ... http://www.amazon.com/Diamond-DP1800-Mobile-Source-Blackberry/dp/B003922S4
Likely it is also available at other retail stores. I can`t research them all.

I think I posted this in wrong area. Mods can you please move to Accessories.

And to report back .. this worked very well. I let the phone discharge through normal use yesterday. Then at night time I plugged in this battery to the phone through the USB connection. When I woke up this morning, the phone was just about fully charged and ready to go. This could be handy if you are running more than 8-9 hours on your phone battery and need a quick or full charge but cannot get to a power source. I also like the fact that it had mutiple tips to connect to other phones. Could be used in a pinch for a friend or co-worker running low on juice. The battery can fit in your pocket and the retractable cable also makes it compact enough to fit in your pocket.

[Q] Car charger 1000mah

Hi everybody, I am looking for a car charger for my HD2. I would like to ask if you think that a 1000mah one would damage the phone?
I have found some on eBay and I was considering buying it.
Please let me know what you think.

The standard mains power adaptor that comes with the phone is 1000mA so no it won't damage it.
Even a 5000mA won't, the phone will draw as much current as it needs.

Thanks for the reply, I was thinking of buying the charger and a car mount, so that I have my GPS needs for this years vacation, but I already had bad experience with a car charger that was not able to charge my wife's HTC Diamond when using GPS, that is why I want to buy a good one.

Try these: They work perfectly for me. The charger is a Motorola original charger.
http://forum.xda-developers.com/showthread.php?t=1130487

I use an original Nokia N97 car charger and I never had any problems. I suggest you do the same, they are a little more expensive than the other ones, but a car charger has to be able to give enough juice to the phone while running. A friend of mine uses a similar charger for his HD2, he even tried a charger with several normal USB ports and they can't supply enough power for the phone.

Thank you all for the replies. I have seen both chargers, and the Nokia N97 one is even cheaper on Amazon. I will probably go with the Motorola one, as it seems to have enough power for the HD2. I was able to find out that its maximum output is 950mah, which is not bad for a cell phone charger.
Looks also like a more durable one, and if the manufacturers won't change the port soon, might be able to get it to charge my future phones as well.
Now for a car mount, I will probably go with the Exomount, as I have read some very nice things about it, plus it is universal, so I'll be able to have it hold much more than this phone.
Hope this thread helps someone with the same questions as I had.

Micro usb is the agreed standard amongst most mobile phone manufacturers to reduce wastage in having to produce umpteen different power adaptors, plus it reduces manufacturing costs.

amen to that , I was tiered of having so many different charges at home. At least at that time Nokia ruled the world (mobile world I mean), and most of them were Nokia chargers, hehe
But I prefer the micro usb norm. I just hope they will not invent a mini micro usb in the new devices. My xperia x1 and touch pro use a mini usb, which was the standard at that time

What is the max that the HD2 can get from the car charger?
I have a 500ma car charger, but when using the GPS it doesn't really charge, it seems that it only gives the same amount as the drain. (few days ago when I had 64% I connected the charger and drove for another hour or so, GPS always active, upon arrival battery was 63%)
will a 1000ma charger "charge" the battery during long drives?

I have a Brodit Active holder it works very well.
With GPS and Navigon on still charging.
I cannot put a link Serch for Brodit active holder HD2

yes that will do the job,
if it does not, solder the 2 inner terminals together and that will make your phone think it plugged into the mains charger
i bought a cheap 1amp usb charger from deal extreme and did the above

Be careful with the soldering. If the charger can't supply 1A, it might damage the phone /car/charger.

can anybody confirm working portable power supplies?

I can confirm the iSound Power Max (18,000 mah) battery does not work.
Zagg Sparq 2.0 (6,000 mah) works if you're not using the optimized port, and the Solio Bolt solar charger (2,200 mah) works as well.

Looking for alternatives too as my 6600mah Lenmar I've been using for my phone is a no go even though it has a 2.1amp. charges my kids ipad no problem.

The Samsung port on my Anker 10000mah unit works fine

Just be aware that it isn't always the portable charger that doesn't work but it could be the cable. Based on the few threads already discussing which aftermarket chargers and car chargers work, you can see a pretty strange pattern of some cables working with a charging unit while others don't.
Just an example, I was testing my 2A Griffin Car Charger last night and it didn't work with the stock cable (Cable that came with the N7). But once I tried it with the cable that came with my Portable Charger, it worked.

My New Trent IMP1000 works with the cable that came with it (retractable with interchangeable micro/mini tips) but not with other cables. That cable also works with several other chargers where other cables don't.

Zagg Sparq
I use this one: http://www.zagg.com/accessories/zaggsparq.php Right now they are giving free pair of 50 dollar headphones with it that are really nice!

I have a New Trent IMP500 and an Energizer PowertoGo. Both will only work if I use the cables and tips that were supplied with the power source. If the screen is on it says charging but the battery level seems to stay the same; if the the screen is off it charged 3% (from 83% to 86%) in 10 minutes - using the New Trent. I have not tested the Energizer yet.

The ZaggSparq is a piece of crap - it suffers from really bad battery drain. Unless you charge it weekly, it'll almost always be empty by the time you need it. I fell for the first generation, which was even worse. Then when they wouldn't replace it, I made the mistake of getting the new version - which STILL has the draining problem.
Get something better - like an Anker.

I picked up the New Trent 12000mah 2a portable power supply.
http://www.amazon.com/New-Trent-Thunderbolt-Blackberry-IMP120D/dp/B003ZBZ64Q
It comes with 2 cables:
-a standard USB to Micro USB (or whatever they call them that come with 99% of devices including the N7)
-what they call a Galaxy Adapter which is nothing more than a 2-3 inch USB extension that you can plug any USB cable in to including an iPad cable.
When i plugged the stock N7 cable in to the power supply (2a outlet) it didn't show as charging.
When i plugged in the standard USB cable that came with the power supply, again it didn't show as charging.
When i plugged in the stock N7 cable to the "galaxy adapter" and then in to the power supply, it did show as charging. Strange that the adapter made a difference but whatever at least it works.
When i plugged in another cable with multiple tips that came with my other Anker Portable charger, that worked too. No adapter required this time.
I did a test and confirmed that with the combinations that work, it is charging at the same rate as the stock wall charger.

The Anker 8000mAh I have charges the Nexus 7 at 2A. You have to use the Anker cable though.

New trent came in before anyone else, mine has been working for a good 3 years.

I like my Sparq a lot. Had it maybe 4 months. Got it on the recommendation of several friends who have all loved theirs. And frequently they are only 50 bucks.
The only issue I have is as stated in the first post, it doesn't work in the 2.1a port. But I haven't found any of the 2.1a chargers I've tried work.

Wireless charger and some questions.

http://www.amazon.com/gp/product/B00F6SPYJS/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
I recently purchased this from Amazon. Not a bad buy for $22, but some quirks. I noticed that if you are going to charge with a case on, you need an optimal charger and cable. With anything less than that, the charger will repeatedly cycle on and off. With case off a 1amp charger will work, with case on you need a 2amp charger and good cable. Also, the sweet spot on the phone is somewhat small, so it needs to be positioned with some precision, can't just be dropped onto the charger.
Here's the one problem and I don't know if its the charger or G2. The phone charges fairly rapidly. So if I awaken in the middle of the night for some reason which I will not discuss here, the phone will be fully charged and the charging will shut down. However, over the rest of the night the charger doesn't turn on and the phone charge trickles down to something around 97%. Even if I take the phone off the charger, the charging won't immediately start up again. I haven't determined if there is a point at which wireless charging will be re-enabled but all works well when I replace it on the charger the following night.

This is the charger. I have a Samsung Qi S4 charger and it will continue to trickle charge throughout the night. When I pull mine off in the AM, it's at 100%.
The more expensive chargers have multiple coils in there to allow "drop and charge" and also have better charging programming to trickle charge.
The cheaper ones work well, but as you mentioned, are a little trickier to find the sweet spot and just turn off when reached 100%. The cheap ones are good for travel and office charging, but I'd buy a better one for bedtime charges.

These get good reviews and are cheaper. I don't own one to know how it operates, but reviews look good. Ebay also has one that I think is the same device for $10.
Here is my Samsung Qi Plate:

Thanks. Yeah, I was thinking of doing that. Using the coil at my work desk and the more reliable plugin at bedtime. At least with a plug in and suboptimal cable, I'll get a slow charge warning but eventually completely charged in the AM.

You won't get the Slow Charge message at all using Qi. In fact I use a standard USB 5V wall plug that spits out 500mah. It complains just using the cable, but not the cable and Qi.
I recommend slow charging bedside anyway (either wired or Qi). You'll get a MUCH longer lasting battery that way. Fast Charging is also Fast Depleting.
