Awesome little battery Charger for Wing, Dash - Windows Mobile Development and Hacking General

Just thought I'd pass this along. This little battery charger for the Wing or Dash charges your phones battery with just one AA battery. It kicks up the voltage from 1.2-1.5v to 5.7v. Saps the hell out of the AA battery but charges the phone -- its really cool. I bought two of them.
I'm Not the seller - I have No interest in selling these. Just thought Wing users would like to know there's such a thing out there.

How long of battery power do you get for 1 AA battery?
If it has small USB connector, can I use it for TyTn II (Kaiser)?

I will time it
Hi -- I've not timed it yet but I will and post results.

Iffy
I got one of those little portable chargers for mobile devices. It's a neat concept. Upon pruchasing one of those (in the US) for $19.99, it came with a cheap AA battery, and several adapters for different mobile phones. I used the AA battery that came with it and it charged my HTC Herald P4350 for 20 minutes. You can actually drain (and cause damage too) your phone battery it you have it plugged in (with a dead AA battery) your device (it said so on the package). This is my experience and others may be different. In a nutshell, the amount of time it charges depends on what kind of AA battery you use. Again, this is my experience.

True
Yes it does depend on the type of AA battery you use. A Lithium AA will give you much more than a rechargable NMHI. I put in an alkaline AA and talked with my brother for two hours today using my Bluetooth headset and this thing kept my phone to 100% charge the whole time.
I am not planning on keeping it plugged in all the time especially when its dead.
I am going to use NIMH AA batteries in my Solar Charger that sits on my Dashboard. Rotate them out and get basically free energy. Hey I know its not going stop the Icebergs from melting but its something.
Here are the specs from the package:
Input 1.2-1.5v
Output 5.7v
Standby 80 hours
Talk Time 2 hours
Charge current 850-2300m
Discharge 150-530m
*This one says nothing about draining your phone's battery in fact it says if using NiCads or NMHI to make sure it drains all the way down before you disconnect it. It says best results can be obtained using a Lithium AA but who can afford that.

It Should work with the Kaiser

Yes it has a mini USB connector and it should work with the Kaiser but you may want to ask the seller to be sure.

Has anybody tried a 3000 mAh battery or AA-battery USB chargers?

I have found a 3000 mAh battery on eBay for around $100 with shipping, and since I'm pretty tired of the short battery life I'm considering it. I was so embarassed when the family went skiing yesterday! My kids have smartphones (Qtek 8030 & 9100 - I keep the family on intelligent phones, my wife has a Qtek 8500 Star Trek) and they had MP3's playing all day in the slopes with only one of the three battery level stripes dissappearing, while I had to put my Atom in the car and charge it after only three hours, when it was down to less than 15 %! Which is why I'm considering either an expensive 3000 mAh or one of those cheap USB chargers where you just put in a regular AA (or was it AAA?) battery and hook it up to the mini USB port. So has anybody tried either of them?
The battery-based chargers work, there are AA and AAA models 'round here (>1 battery each) - but I haven't tried it on the Atom yet. Be aware that the Atom has a charger protection mechanism that refuses to let the battery trickle charge if it doesn't provide a rated amount of juice (this is not mentioned in the O2 site, but it's there. It's the reason why chargers that normally work on the Mini won't work on the Atom).
Personally, I'd rather get a charger that works practically everywhere than to grab an extended battery.
(Have you considered those new fangled solar powered chargers? Some of them contain internal batteries that store energy, even under artificial light - and it is this battery that is used to charge your device. This could be a better idea, but be sure to check if it works on your device.)
PS: a PDA eats battery like no tomorrow because it usually uses better processors and interfaces - the XScale on ours is the eater here. Smartphones run on a lower rated processor/card slots, and don't have touch sense screens, and thus can last for much longer. If you really need your PDA to last, well, forever - you might want to consider an extended battery or one of the CPU scaler programs.
Thanks! I forgot to say that I ate the battery with the CPU at 208 mHz (with XCpuScalar)... Anyway, I have two of those AA-chargers on the way, I'm glad they work! At home I have GP PowerBank chargers and a bunch of rechargable batteries which I will use for this. With any luck a few of those will last me all day on skis!
And I didn't know about that protection mechanism in the Atom, I have been wondering why it's so extremely picky when it comes to charging from USB cables and stuff like that.
And I hadn'd even heard about the solar charging option, but I see there are a bunch of those on eBay. They look pretty cool, but unfortunately when I'm in the sun I seldom stand still long enough to put the charger and the phone anywhere for charging. If there was an affordable vest or jacket for that, though...
I think the O2's charger protection mechanisms were discussed here:
http://forum.xda-developers.com/showthread.php?t=276400
Methinks Quanta borrowed something from Motorola.
The solar charger, btw, works under incandescent light as well (I have one - useful in a hotel room where you don't have a plug but you have access to a desktop lamp). More expensive models can supposedly work under flourescent light, but I'm a cheapskate. They work by having an internal LiON themselves, which is trickle charged by solar/incandescent power - and then the battery itself is the one that charges your PDA's battery. Many different types exist, but most of them have a 1000-3000mah internal reservoir, and the better ones have different voltage settings for differenet devices.
Yeah, but the problem is that they're too big for my jacket pockets, so they won't help me skiing.
Well, that didn't really work. So I have decided to go for quantity instead of quality: Ordering three batteries, one with a charger that charges it ouside of the phone as well as charges the phone. All in all around 40 dollars, which gives me four batteries to play with. I ain't gonna use up my phone next time I'm in the slopes! And I think the same batteries can be used on my next phone, the Atom Life. It's got a larger capacity battery, but it looks like it's the same physical shape. Then again I may be wrong, but at least I will have no problems on those boat trips this summer!
And that worked! Not to mention that the original battery has to be total an utter crap! On these new batteries I had more than twice the battery time I had on the original. Of course it's been used for about two years, but still it shouldn't be that bad! I have five year old PPCs that hasn't changed that much in battery time. Anyway, with three new batteries and the old one I can keep going for a looong time!

Some types works, some don't. It seems like only the black type work,while the shiny metallic one doesn't.

Anyone use these battery chargers?

Anyone ever use one of these?

Please comment on:
1) how fast they charge
2) how much they charge the phone
thanks!
The kaiser battery is rated for 3.7 volts and the battery that device uses is 1.5 volts. It would charge at the same rate, but drain the AA very quickly. The cost of the batteries it would take to power that thing would quickly outweigh the benefits it would produce. If it had 2 AA wired to it then it might be remotely useful. I mean if you absolutely cant survive if your phone dies, then yes it would give you enough battery life to keep your phone going for a few hours.
Yeah...well I bought two cheapo spare 1600mah batteries of ebay with the thought of carrying one around with me to swap out if needed....but I was considering getting one of the 2-piece rubberized cases for my phone. In that case, the battery compartment I believe will be inaccessible and I don't want to snap off the back case constanstly and wear down the integrity. Therefore I thought something like this might be a good option.
Even with free access to the battery door, I would think opening it up on a regular basis to swap batteries isn't good for it (would get loose, etc...).
Motorola P790
Well, I used Motorola P790 and it is pretty good, rechargeable. I can recharge it together with my phone with one charger. It gives abt 30% recovery of your battery in abt 2 hr.

Not really, these units have a small switching power supply which boosts the voltage to be able to charge the phone (if you look at the picture you can see the copper inductor coil for the oscillator circuit inside the top clear piece), a Kaiser won't charge with an input voltage under 5 volts.
I don't know how long it takes to charge, but I doubt that you can get more than 1 good charge from a fresh battery.
I've had all sorts of charging problems recently. With the Wifi, GPS & Phone on it would use about 500ma of power. But if I was running SatNav it would actually use about 850ma.
What I've done is twofold. I've bought a 2700ma internal battery for the phone and I've got a 12-24v charger that puts out 2a (2000ma) and so far it has kept the device fully charged, even with Bluetooth running!
I'm not sure how to gauge the 2700ma battery as I've only been running it a day. I think it needs a bit more of testing before I use it full time without the spare, but it's also good to have the spare....

Charging via car charger while navigating (long GPS usage time)

Hi all,
It is really exciting to see how a new device's forum gets filled up so quickly . (i'll be getting my device sometime today so I feel like a small kid waiting to go to the candy store hehe)
I did do some reading on http://www.batteryuniversity.com/ and also in different parts of the forum.
But i am not sure how this case fits in all of the battery discussions out there. If am going to drive in the states for 3-5 hours a day where i;ll need to use my phone afterwards to continue my day.
Will keeping the phone plugged in the car charger hurt the battery?
Thanks all.
The best to do in order to increase your battery's life is to let it drop to 5 or 10% then plug it on your car charger.
It will last longer then if you keep it plugged on the charger, that's for sure.
On the other hand, the average life of a battery of this type is between 1 year and 1 year and a half.
Personally I keep a second battery with me all the time.
That's what I used to do with all my previous devices so I never be short of battery
Thanks, then i guess i'll play it safe and recharge when it goes low on juice.
If i dare ask, given the scenario where you disrubt the battery while charging, would it hurt it? I read that it is better to keep it charging once plugged in, but then again this is Li-Ion which should not get hurt if you take it out while charging!
Thanks
Not charging in the car
I noticed that when I have my device pluged into car charger and use it as GPS, it does not charge or loose power. In other words, if it is half-charged when I get into the car, and I drive for 2 hours, it is still half-charged, no more and no less.
What is going all?
Thanks

This is correct, but for the good of the battery you need to have it down to 5% (or less) from time to time

I used to have this behavior with my HTC Athena, but did not see it yet on the blackstone. I'll check in the coming days and will let you know
Hi Fadik,
I'd recommend just using your GPS and charging at the same time. Go with BigDede's advice and let it run down a bit before plugging in. This will help avoid possible overcharging.
Compare this with what most laptops are put through - permanently connected to the charger and hardly ever being used on battery. Our Dell still has more than half its capacity after three years of this. If you are still using your HD in 2 years, give a battery as a birthday present!
I don't know of anything that would damage your phone's battery during normal usage. The main battery killers are deep discharge (protection circuits turn your phone off before this point) and very high temperatures (you weren't going to leave your HD on the dashboard of the car during summer while you shop??). Oh, and the obvious, including blocking your car's wheels on a hill, providing canine nutrition, etc...
Hope this helps...
Thanks all for the feedback and input.
and I guess, I should replace the battery every year and a half

This is a common misinformation.
Do charge the battery often. The battery lasts longer with partial rather than full discharges.

Avoid full cycle because of wear. 80% depth-of-discharge recommended. Re- charge more often. Avoid full discharge. Low voltage may cut off safety circuit

No maintenance needed. Loses capacity due to aging whether used or not.

All quotes from this handy table at batteryuniversity.com
So to adress the question of the OP:
Your battery will probably do just fine, as long as the pack itself does not heat up too much from the prolonged charges. The battery it self should be protected from overcharge, and tickle charge should not hurt it.

Im talking about personal experience here
I got my 2 batteries dead in less then 2 monthes on my HTC Athena
due to charging the device everyday while on 50% or more. (Actually charging it in the car, in the office at home, etc ...)
The 3rd one lasted more then a year when I was letting it drop to around 15 or 20%
Again, this is personal experience

I had this same thing when charging through the USB port in the car stereo. I had to revert to the dedicated car charger providing power from the cigarette lighter socket to get it to charge.
Hello
I had some trouble in the past, charging an Ipaq in my car.
You have to check how much the device can provide.
I think the wall charger is giving 1A.
On my USB car charger it could output 750mA. Maybe that's enough to maintain battery level in the case of the HD in GPS use.
I'll check.
You can check how much your usb on your car radio/USB can provide.
But I suppose it's 500mA which is the standard level given by a PC.And that may not be enough.

I bought this, it took about 2 weeks to get to me,(but for 12.99 for 2 batteries and a wall charger) as it was coming from hongkong, but got it yesterday, and its great, 2 extra batteries, and a wall charger so now i dont even need to charge my phone, i let the battery die so i can train them right, and just pop in a fully charged one when needed. the charger even has a usb hookup like the original wall charger that came with it, so really you could charge an extra battery, plus the one in the phone through the usb cable. The batteries are the same as the stock one that came with the phone. I wish i would have done this with my G1, instead of spending 90 bucks on 1 extra battery that didnt even have an external charger.

I got the same type of deal on ebay, 2 batteries & the charger (did the same thing with my MT3G as well), it's always nice having extra batteries, and I can use the charger when I'm traveling (it will also charge up my PSP). Now just need to get a mini to micro USB adapter and I have one less cable to carry around for charging - although I recently got an external drive for data storage, so I guess I will need a second cable if I want to tether my phone and use the external drive.
The batteries are not as good as stock and one seems to hold a charge better than the other (have to mark them so I remember which is which - these are generic one without the Samsung label), but as I train them via charge, use until dead, swap, charge, this should at least max them out a bit. The ones I had for my MT3G actually outperformed the original battery that came with so was hoping for the same. But considering how cheap these are, I could even pick up a couple more.

Those batteries from Hong Kong are not an original Samsung battery, they are just compatibles.
The lasting power of a li-on battery depends not just on the mAh, also the circuit inside the battery counts much of it.
The circuit takes care of the special sleep modes and energy saving features of a battery.
Samsung has its own energy saving codes that can not be put into a common compatible batteries.
This is why an original one is much more expensive than a compatible ones.
Extended battery for the vibrant, lasts twice as long and great door
Check this out: Moretalktime's feedback is 100% and the door is soft rubberized--better than stock IMO. It cradles well in your hand in a very comfortable position and lasts over twice as long.

Re: Batteries not lasting all day
I'd like to throw in an observation on this thread. My battery life is quite good on my Vibrant. Lasts all day easily but there are a couple of things to take notice of. First, I do not use any task killers or such, but I do check if there are any running programs with the built in task manager and stop them once I'm through with them. I've found that Voice Search and Web Access continue to run even after I've closed or backed out of them. Thus the need for use of task manager. But here's what I really found out. I've always charged my phone using the wall adapter with USB cable plugged into it. Never had a problem with battery life. Then for some reason, I decided to start using the USB cable attached to my computer. It would charge as normal and each morning it showed 100% charged. But after about 1 week of using the USB cable from the PC to charge the phone, I started having the horrible battery issues that I've read about. Extremely fast discharge. Leave at 8am and have like 50% use at noon. Crazy. So I started using the wall charger again and the phone has returned to its original state, easily lasting all day. Just a heads up for some of you guys having battery problems. No idea why this has happened but I've confirmed it. Maybe the Power Management thing on the USB ports on the PC?
I just saw this thread after a search on Google. I already posted elsewhere, but this looks like it might be the battery some of you are looking for.

If nothing else, they also sell a 1600mAh battery which is 100mAh larger than the stock battery and still fits unter the stock cover. Good Luck

Solar Phone Chargers

Since running Android on my Leo, I have noticed that my original Leo battery gets depleted twice as fast. So I've been looking into portable battery chargers, and I also stumbled upon solar phone chargers (battery also included).
Is it worth investing (although it isn't very expensive to try anyway)?
Wondering if any of you have any experience with a solar charger? If so, what battery capacity did you get (1000-2000 mAh, 2000-3000 mAh, etc)?
haven't tried it personally, but here's a link if you want to make one for the HD2 yourself:
http://forum.xda-developers.com/showthread.php?t=1028409
it's still not complete though.
I've kept it in my bookmarks just in case I decided to make one for myself one day
I had a cheap solar charger without battery. It didn't recharge the HD2. It was full bright sunlight inside the car.
It was enough power to trigger the phone to boot up, but it couldn't charge the phone battery. I get the feeling it probably drained the phone battery..
I bought an extended battery for the HD2. That lets me use the phone with GPS running continuously for about 12hrs.
