for heavy days... do you think it's possible to have it for HD2?
Yes Please, and make it at least 2700, then it's up to standard. (Rechargeable batteries AA these days can reach 2700. So what you really want to make it count is 2x2700 mAH in a slim formfactor with the HD2's fit and a micro-usb connection. And while they're at it add smart technology so the phone runs on the external battery pack and not the phone's battery (like the mophie juicepack on the iPhone).

I got one of these from Taiwan:
http://www.amazon.co.uk/Vosonic-Battery-Universal-portable-devices/dp/B001J32ZSW
The price at Amazon seems crazy though. It costed me about £70 and I get about 5 charges with it using Hero. I have not yet needed it for HD2 but I guess total charge cycles should be similar.
Full specs here:

It is not as big as it looks and gives a piece of mind when traveling.
Hey, guys!
Found this over the net. One problem - it gives out 1200-1500 mA according to same German sites. I wonder if it is not too much for HD2?
No it's not too much.
The mA rating means that the charger has a MAXIMUM output of ...mA. To illustrate: the official car charger from HTC for the Diamond2 has a max. output of 2A (that is 2000mA).
For instance, a universal laptop charger may have a max. output of 120W (as you may know: power (W) = V x A), but your laptop only needs 90W to be able to run and (or) charge. So your laptop demands only 90W out of the 120W the charger can provide.
Thanks, I'll try it.
Hi guys,
I have bought this interesting gadget and wanted to draw your attention towards it and ask your opinons and views. This post might be helpful to particulary those who doesn't want to compromise the looks of their HD2 with the bulky extended battery "The Camel Hump".
Also I am attaching some pictures of my device. The one that I have is version 1. In version 2.0 one of the 2 USB outputs can give power upto 2000amp while in version 1 the USB outputs are only 1000amp each. So please guys post your views and help others making good choices, or on the other hand save them from pain or waste of money.
Although they advertise on their website only Iphone and Ipad, it does work with HD2 and any other device that can be charged with a USB.

does it work with htc desire? has anyone tried so far.
urh.. i've read about this before.
it took like 9 hours to charge itself and occasionally drain the connected phone battery completely :/ did they fix that? (version 1.0)
how many charges can you get out of that with the hd2 stock battery?
I just bought one of these (with a 50% off coupon ) and it works as advertised. I've only charged the phone once so far, so I can't comment on longevity yet.

T-Mobile HD2.
I bought the official HTC version of this for my TP2 (and now using it for my HD2), and it works great! I just keep it in my bag and whip it out (along with a USB cable) when i'm out and about and the mobile battery is about to give out.
The Sparq 2.0 looks good, especialy as it 6,000mAH, which you should be able to get a few charges of the mobile out of. Does it work? Or do the problems Rhinzo mentioned still exist?
I bought this battery two weeks ago. It does work with the HD2. Based on the capacity of it one would assume it could last up to 4 charges but I find this is not the case, I get about 2 and a half full phone charges out of it. Note that:
- I left the phone plugged in overnight (so longer than a full charge would take)
- I haven' "trained" the battery yet to reach its full capacity
- Efficiency of charging one battery out of another is probably not 100% in any case.
Alternatives which I haven't tried are the powergorilla and minigorilla batteries. They are a whole lot more expensive though.

So which is the Best to buy? If you guys know of any others please post a link I don't know the charge values for the extended internal battery also.
a cheaper suggestion
Might I recommend trying something like this. 2x Battery w/ charger
I bought something similar for my Nexus one and I just rotate the batteries around using about 2 a day (including the oem one).
From my experience, the generic battery holds a bit less charge than the OEM one, but you have two + external charger so you'll always have a battery ready.
And if they are both super crappy you only wasted $10 but a potential to save $50 from the options you are looking at.
Just a suggestion but ultimately up to you. I'm probably going to purchase it right now. (o'yeah, it also took 2-3 weeks to arrive because it's form Hong Kong/China. Not sure about this seller but read the reviews before you buy)
I bought a USB power output box powered by 4AA rechargable batteries. Power box was about $7 & 4 UniRoss HyBrio cells was around $8. Charges my HD2 close to 3 charges (charging from around 10>15%, device on).
Charges all devices I have tested so far (HD2, Desire, Touch Pro, N97mini, N95)
For the money it is very good, compact & cell quality is your choice & obviously replaceable which makes this option fully serviceable unlike sealed power box options .
Best External Battery Charger
I have two portable external power solutions. The first is pre made by Energizer, holds 4 AA batteries even lithium and is for short term, low demand situations. This uses I-Go adapter tips
The second is made of several components that are easy enough to obtain. Bendix-King radio has an accessory called a clamshell, it holds 9 AA batteries and can replace the OEM battery, an enterprising firefighter created a block of aluminum that connects to the top and has a hole in it that will fit a 12-volt accessory/charger. The next item is an I-Go 12-volt charger and adapter tips for your specific device, I use the USB adapter and the charging/data cable that came with the device. Lastly you will need AA batteries. I pick up a package of 36 at Home Depot for about $15. I have used this system for a while now, most notably for 3 cross Atlantic trips (22 hours each). The last trip I watched 16 hours of movies on my HD2 and used 2 sets of batteries. This system won’t charge and run an Acer Aspire, but will charge/run a Redfly or the HTC Shift 9500. I don’t know the mAh for this, but know it will work for a long time. I use regular alkaline batteries, the lithium batteries got uncomfortably warm on larger power drains.
You can search the net for Bendix-King Clamshell (beware BK has an avionics division that is separate from the radio division). The Clamshell is even available in different colors. The I-GO is available at Radio Shack, and AA’s are available everywhere.
I have included pics for clarity…. I hope.
(I made the HD2 holder as a prototype but it is still holding up well)
I got these two items from amazon when the usb port on my phone broke. The total cost was 35$ with prime shipping. The good thing for the charger was, it can charge any standard 3.7V Li-Ion batteries, not just the HD2's battery.
PowerGen Multi-Purpose Universal Rapid Battery Charger for Use with HTC Inspire 4G , HD7 , HD2 , Surround
Htc HD2 Extended Cell Phone Battery (2400 mAh) with Battery Door
External Battery Charger
I have this same model, but my only cost 5 euros!
They are very good chargers!
I charge my hd2, or any other phone w android, using a China brand tablet I bring about. It works through USB charging though. Better than not having any battery at all.

Question: What happens if I connect a Nokia AC-10 Micro-USB charger, that has an output of 5V, 1200 mA, into the phone ? I'm asking this because inside the phone, on the back of it, where the battery compartment is, it says maximum of 1000 mA.
So what would happen if I would connect the charger ? Would it end up in smoke ?

It depends on what the voltage rating for the phone is, if it is 5v, i believe it should be ok, you may find it actually charges slightly faster, if the voltage is higher thats when you can cause damage though.
I am not 100% sure on this maybe someone else can confirm
Phone: 3.7 V, 1000 mA
Battery: 3.7 V, 1500 mAh
Original Nexus S Charger: 5 V, 700 mA
Nokia AC-10 charger: 5 V, 1200 mA
Charge time = battery mAh / charger mA = 1500 / 1200 = 1.25 h = 75 mins
So the NS battery should charge in 75 mins with the Nokia AC-10 charger.
So all the chargers are 5 V rated, ranging from 500 mA (USB cable) to 1200 mA this Nokia charger. For example, with the HTC Desire, I had an 1000 mA charger that worked flawlessly.
LE: Never mind, I found the response. Sorry for making another thread on this matter, but I didn't find the other topic when I first searched the threads. http://forum.xda-developers.com/showthread.php?t=897935
If a mod sees this thread, please, do delete it, because it's useless now. Thanks a lot anyway !
Just on a side note: Your phone will not necessarily charge faster just because your wall charger can supply more current.
It depends on the charging circuit inside your phone, too. If your Nokia charger and the Nexus S conform to the USB charging specification, the phone will know how much current the charger can supply by the resistance between data+ and data- on the USB-plug. But how much current it draws is up to the phone.
Also, charging LiIon batteries is not as straight forward as (battery mAh)/(charger mA).
It will (most likely) be charged constant current at first and later switched to constant voltage top off charge. I read somewhere that the faster you charge at the beginning, the longer the top off will take.
So you will only gain time, if the supplied wall charger was too weak anyway and why should Samsung do that?
In any case, if you want to try anything you should be sure to be inside USB specs. I think it is 5V +- 5%, so from 4,75V to 5,25V. Less should not be a problem, but (much) more can and will fry your phone.
Good to know, thanks a lot ! Maybe I'll come back here with a comparison between stock charger and the Nokia one (in a couple of days).
most definitely not
i'm using a 2Amp car charger, and it charges really fast, even when the phone is ON, full brightness, gps + streaming BT to car audio

i would think that it would charge faster with your nokia charger but your phone will get hotter than normal. i experience this when i use my 1A charger. 1.2A will make it even warmer. i hope you dont overheat your phone.
ps. fast chargers (15 min chargers) for Ni-Mh batteries have 7.5A. those kind of chargers come with fans on them to cool the batteries while charging because it gets really hot.
Ok guys, thanks a lot, I'll keep in mind all you said. Unfortunately, I've come across a dead Nokia AC-10 charger (don't ask, lol), so I will need to get another one tomorrow. After that I'll compare the 2.
The charging circuit (in the fone) tries to stop the battery blowing up and overheating by pulsing the charge until the battery reaches 70%+ when it drops off and the charge creeps up to 97% (all values approx) when the carge circuit switches off and we are left with a fone at 97%+ (other threads on this topic itself !)
I experimented with standard Nexus AC (700mA) and USB Wall Charger (1000 mAH) and Laptop USB Cable (500 mA) and 1 am disappointed at not being able to get a FAST charge in the thing. Here is a plot of the AC Charge (700 mA charger). It never gets used a full power !

Ok... something is really screwed up... when I connect the phone via the Nokia charger, the touchscreen goes haywire... If I touch it in one spot, it sees the touch in another spot... It even starts apps without me even touching them... weird. Is it too powerful for the phone, or what ?
The nokia charger might not be isolated enough from mains. Too much ripple or whatever. It is unlikely IMHO, that it supplies too much current, since it is no current source, but a voltage source.
in case any one wants to know
2 Amps (2000 mAh) Blackberry charger
this is exactly the one i purchased from them http://www.dealextreme.com/p/design...lackberry-9800-9700-8900-8520-dc-10-30v-57622
been using it for over a year now, since i had my old BB and SGS i9000 and kept using the same one for SNS
i use it on a daily basis, as the first thing i do when i get on the car is to plug the charger and put the phone on winshield
Interesting enough, another one from the store has the same effect. Also, on my girlfriend's HTC Wildfire it has the same effect. Guess Nokia sucks as this as well. GG Nokia, keep it like this and you'll eventually fall like the rest of them...
I have noticed too that when the fone is on charge, the screen sensitivity is maxed out and phantom touches can occur all over the place. So much so that I unplug the charger to send sms as I can't type well enough for the spill chucker to guess what language I am using let alone what the word might be !
Anyone found the cause of this annoyance ?

The voltage is not current.
It used to happen on my desire when i bought a 99 cents micro USB charger.
By the way i ordered a AC 10 E yesterday so i am a bit worried now.

I encountered the same situation like you, and I know many people do. I was told by my cell phone supplier that it's all due to the unstable current, which causes magnetic field to influence the scree. Or something like that. My phone even typed words or made calls by itself when charging, I can hardly control it until I stop using the charger. When I connect it to PC with USB cable to get charged or use another charger, everything goes well. So I suggest you stop using the charger on your phone. It might cause damage to it.
Charged mine with a nexus 7 charger, which had at least 2 Amps... Worked fine for me...
