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

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.
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.
Hello,
i ve been searching for a way to extend the autonomy on the a501.
do you think i can use a cheap 12V lithium battery to charge it or take over when the internal battery is depleted ?
i m not very knowledgeable in electronics, i wouldnt want to damage the internal battery.
there seem to be very few commercial products that would fit this tablet and i m not really interested. i dont have 50$ for a +2h battery life --;
i was thinking of buying a 12V 5000mAh something battery from china and solder the appropriate DC connector on it, but im wondering if there are issues like, the Current needs to be stable at 1,5A or i might reduce the internal battery durability, things like that.
can anyone answer that ?
It's more complicated than that. The power supply probably has a circuit to regulate the flow of energy to the tablet, perhaps the tablet itself also has a circuit that works together, I don't know.
Short answer: buy a second power adapter
There are backup battery/chargers. Scosche goBAT for example.
Just Google around to find the best fit for you.

this guy for example http://www.youtube.com/watch?v=LqxhEkDGkbg he says he learned it the hard way (bricked his phone?) because he put 4x(1.5V?) batteries to charge his iphone without the resistors (to get the voltage from 6V down to 5V?)
so there again, can there be issues with the discharge current rate or is it something about lithium batteries behaving differently from alkaline ones ?
i think i ll go ahead and try anyway. worst case scenario the battery will just sit there not putting out anything.
Why wouldn't you pay $80 for a backup battery charger. It was just an example. I'm sure you can find one cheaper after Black Friday, or even with a bit of Googlefu.
We aren't talking about normal chargers but portable charge devices.
http://www.scosche.com/consumer-tech/product/2073
For anyone in need of extra power, the goBAT II provides an innovative solution to the dreaded ‘low battery’ warning. The goBAT II is a powerful backup battery and dual port charger for your mobile devices. The internal 5000mAh ion battery will keep your devices going long after they normally would.
Advantages and Applications
A drained iPhone 4 can be charged 2.6 times with a fully charged goBAT II. An iPad can be charged up to 55% of full charge. This is the ideal battery for long commutes, airport travel and camping.
The goBAT II provides 2 USB charging ports that can be used at the same time. A 2.1 Amp port gives you the ability to charge mobile devices including tablets (iPad and Samsung Galaxy Tab). An additional 1.0 Amp port lets you charge your additional devices (iPhone, iPod, etc.).

Remember this is JUST AN EXAMPLE. The idea is to show these devices exist and are available for purchase.
http://www.engadget.com/2011/02/23/scosches-gobat-ii-portable-battery-pack-handles-two-usb-devices/
We'll just keep it real simple for you: the object you're looking at above is the Revive II charger, but slimmer, and with a rechargeable battery pack thrown in rather than a wall / cigarette adapter. Got it? Good. The goBAT II contains a 5000mAh rechargeable lithium ion battery, and it offers a pair of USB ports for charging. One's a 10-watt (2.1 Amp) port capable of handling high-maintenance devices like Apple's iPad, while the other is a more conventional 5-watt (1 Amp) socket. Scosche is also throwing in a USB adapter for the Galaxy Tab, theoretically letting those with divided households charge both an iOS and Android tablet at the same time. Brain melting, we know. It also works with the company's Revive charging app, which indicates how long a device will take to charge on any of Scosche's chargers and can also be configured to send an email notification once a device has been fully charged. She's all yours down at the source link for $89.99

See, others deem it "BRAIN MELTING".
And the cost of that type of thrill is reasonable, for the job it does.
But I can understand how someone would encourage another person to experiment with the guts of electronics they don't fully understand. Screw it up and you can always buy a new one.
Then again, you could buy three or four Gobats and save all the fuss and bother.

You will break your tablet.
The charger contains a complex integrated circuit. Sticking on a few resistors isn't gonna do ****.
Look at this for example, a simple wind generator has a complex charging circuit to regulare all the power:
http://www.instructables.com/id/How...nd-turbine/step8/Build-the-charge-controller/
Just google "how to make a charge controller" it's really not as simple as you think.
Quote from the site:
The general principal behind the controller is that it monitors the voltage of the battery(s) in your system and either sends power from the turbine into the batteries to recharge them, or dumps the power from the turbine into a secondary load if the batteries are fully charged (to prevent over-charging and destroying the batteries).
ok thanks ^^
now i understand that part
Short answer: buy a second power adapter
Click to expand...
Click to collapse
you are saying the overcharge controller (and other safety features) are all in the wall charger and are not integrated in the tablet.
so if i really really wanted to try i could plug any battery between 12 and 24V to this little guy couldnt i ?
http://www.ebay.ca/itm/220826123824#ht_3149wt_1163
As far as I know...as long as the voltage is correct (eg 12 volts) and the power adapter can produce the required amperage (1.5A) then the tablet will only take the current it can use.
So even if the power adapter is capable of producing 10A say, it doesn't mean it's forcing the 10A onto whatever is connected to it. If you use 1.5A (and if there was a way to connect multiple devices to it) you would still have 8.5A of current you could still take.
Oh the charge regulator would not be in the power adapter, that would be a very stupid design. It would be in the tablet it self to regulate how much charge it requires. I don't know of any power adapter that takes feedback from what it's charging to regulate the current.
It's the same with laptops, that's why you can buy universal laptop chargers when the one you have breaks, you just need to make sure it can supply enough amperage to power your device.
The power adapter is just a simple device that converts 110-240v 50/60hz voltage to 12v and upto whatever amperage it is designed for.
Power plugs in the house are designed at 110-240v to a maximum of 2400W (so ~20a for 110v and 10a for 240v) do you think whatever you plug into it uses up 2400W of electricity at once? No, it just takes what it is required (amperage), that's why you can plug a power strip with like 2-10 additional plugs without any problems unless if try to take more than 2400W in total.
Basic high school physics should of taught people this.
first sensible answer i get thank you daemos i m just not gonna take any chances considering the lithium technology and the fact they could use a "stupid design" for shorter gadget lifespan. if anyone has ever modded a car charger i d love to read about it.

Lithium ion batteries must be charged at a very specific voltage. So all charging regulation mechanisms would need to be inside the tablet.
I'm pretty sure the ones inside the tablet are definately below 12V so anyone thinking that the AC adapter has any fancy mechanisms to detect feedback, and regulate charge and control the voltage given to the Li-ion cells is incorrect.
Is it safe to use one of THESE to charge or run the tablet?
They also have a 6800mAh ver.
WOW YOU MEN Complicate everything
SIMPLE EASY .. Look at the output voltage of the the power brick for the iconia.. the part that you plug into the wall..
got something that OUTPUTS 12V AT 1.5 AMPS and you are done.. the Li Batteries as in all LI BATTERIES HAVE THERE OWN charging regulators in them.
The reason for this is because if a Battery is drained to a low state it will GET HOT AND OVERHEAT.. NI-CD Batteries can take and handle this heat.. Li batteries become a mini bomb at these temps.. So the are self regulating.. This can be proven by getting a cordless drill hold the shaft from running.. the drill will heat up the battery the device will STOP FUNCTIONING.. Remove the battery and put it back in . it will work again..
Now with that said.. most Li devices say make sure you have 20% or more battery life before flashing and so on.. This is because the DEVICE WILL NOT RUN On the power port. the port only connects to the battery. and in some cases the display lighting.. My cell is this way. if i run the battery until its dead or using gps on it. it will drain the battery faster then it can charge . causing it to not work until you charge it for 5 minutes or so.. this would assume that using a external battery to charge it .. the external batteries themselves would need to be more then 12 volts and atleast double the amps.. then regulated to the 12v 1.5 amps . think of this like pooring water thru a funnel.. to maintain the 12v 1.5 amps. You can test my theory by taking the battery out of your cell phone and trying to run it just on the power adaptor only.. I KNOW MINE WILL NOT RUN.. however if it has older battery technology it will..
I'm wondering if the heat I hear about being generated before the charging rate slows down after 50% would have any negative impact on battery life. Would there be any benefit in using my multi-port charger for overnight charges when I am not in a hurry to charge the battery?
Also, I assume that the battery doesn't have any memory, and that there's no reason to break it in, fully discharge periodically, etc. and that it's okay to charge a little or a lot regardless of the current charge state. Is that correct?
This is a question i would like to know the answer to as well
I did a slow charge last night and the battery seemed to discharge s little slower this morning fwiw, but that's not terribly scientific.

Fast Charging Lithium = Battery damage. It's basic chemistry. The cells take mechanical damage from expanding too quickly. So, for best longevity, charge her with like a .7 to 1 amp charger.

wrong. the only thing that damages cells is charging beyond the voltage specifications. How fast you dump electrons in has no negative effects, its only when you put too many in that batteries get damaged.

Thank you. I had thought the same thing. No one had the time to give me any detailed information, so I researched. I can't post links, but the following articles are helpful and will show up first in a search for the title
'Will speed chargers kill your battery?'
'BU-401a: Fast and Ultra-fast Chargers'
A conventional phone charger can only supply the current and voltage that is safe for a battery at all charge levels. In other words, it is must use the least common denominator. Quick Charge makes this process much more active by monitoring max current, max voltage, and temperature so that it can supply more power when it is safe and less power when it is not. Quick Charge will always keep the current, voltage, and temperature within the battery's designed specifications.
In terms of battery memory effect, no, modern lithium based batteries do not have any sort of memory-like effect. This is mostly associated with older and cheaper NiCad type batteries. This is one of those things that people seem to have a really hard time moving past.
People worry far too much about babying their battery.
Assuming you are going to use the phone for ~2 years then a properly designed fast charger should have a negligible effect on battery life. After 2 years of continuous usage all bets are off whether you used a fast charger or not.
If you really want to worry about how to treat your battery then there are two things you should try not to do. Don't let the battery go all the way to 0% and let it sit like that for a year. Don't leave your phone on your dash in direct sunlight everyday. Outside of those two things there's not much you can do to change the lifetime of your battery so just use the damn thing. =P

I had researched the topic and learned what you have stated, but I really appreciate you taking the time to write this fuller explanation. I wished to take every reasonable precaution to maximize battery life, given the battery is not easily replaced.
There have been references published claiming that charging faster (higher current) shortens overall Li-Ion battery life.
Mechanism may be related to heat.
One thing the Qualcomm Quick Charge 2.0 (used in the Snapdragon 808) does is increase voltage at the charger from standard USB 5V, to 9V and 12V, for higher charge rates (power) at still-moderate current (to keep heat dissipation down).
I measured 1.1 to 2.3 amps at ~9V with QC 2.0 charger on the MXPE, with the higher current measurements at lower State of Charge (SoC). Have not seen 12V yet, but I only tried it down to 45% SoC (2.3 amps at 9V), I imagine it bumps up to 12V when the battery is discharged further, nearer to complete discharge.
This charger is rated for
5V, 4A
9V, 2.22A
12V, 2.5A
20V, 1.0A
So the max power fed to the battery would be 28W (12V*2.5A).
(This is the Power Partners PEAW30-12-USB, supposedly a 30W charger. So much for integrity in advertising.)
So the current is kept to a manageable level to control heat dissipation (therefore max temperatures), from the charger to (somewhere in the phone). But I believe that at the battery itself, more rapid charging (higher power) would still require higher current, because voltages have to be limited in the battery itself, so one would think heat dissipation (> max temperatures) would still be a problem in the battery itself. Does that shorten battery life?
The answer is probably: Who cares. Because: Li-Ion batteries have a 2-3 year life in any case, regardless of their service life or even if they are not used at all. They age and exhibit substantial capacity decline over time. Discharge/charge cycles hasten the capacity decline, but the battery is only good for 2-3 years, give or take, no matter what. And since aftermarket replacement batteries are inferior, unsafe, and stale, there is no reason to try to hang on to your phone for more than 2-3 years in any case. (Especially since the "non-user-replaceable" batteries can be a pain in the a** to R&R. The Moto X Pure 2015 battery is one of those. Some phones actually incur permanent damage to seals if the battery is removed/replaced - the Kyocera Hydro Wave is this way.)
You say "but you could replace the battery with an OEM battery". There are two types of OEM Li-Ion phone batteries on the market that an individual consumer can buy retail, when their phone is 2 years old or more: Used stale batteries (look up "reverse logistics"), and "new" (i.e. not put into service yet) stale batteries. Good luck finding a fresh, new OEM Li-Ion battery for your 2 year old or older phone (out of production for at least a year).
Been down this road before. Wasted lots of time and money replacing phone batteries after 2-3 years. From now on I'm going to stop coddling phone batteries, stop replacing them after 2-3 years, and just figure on a new phone every 2-3 years. It's the only way to get a fresh, new Li-Ion phone battery. (And get the phone right when it is released, like the MXPE this month. That way you are more sure the battery is fresh.)
I think everything in the wireless phone paradigm is increasingly heading that way anyway. Everything, and I mean everything, pushes the market to a 2 year product life cycle. Batteries last 2 years. Increasingly, batteries are not made to be replaceable. Carriers are changing networks so fast you need a new phone every 2 for that alone. New OS/SW overloads hardware older than 2 years. Displays may fade over a couple years. USB connectors wear out. Just relax and go with it. Marvel at the Qualcomm Quick Charge 2.0 (I am). You'll be happier with a new phone every 2 years.
Sorry for the long rant.
Sorry for the kind of off topic, but it's kind of related... is it okay to use other devices with the included fast charger? I just hate having 2 micro usb chargers plugged in, when I could use just one

Yes, the Moto Turbo Charger can be used with any MicroUSB charging device. It will adjust charging as needed for the individual device. Moto made the Turbo Charger, to be a single charger for all MicroUSB devices.
If the battery is kept well charged, which Turbo Charging helps to accomplish. That's better to me, than more drain and slower chargers that leave the battery more drained overall. The batteries are supposed to last longer when kept fully charged more often.

"...since Quick Charge 2.0 is compatible and interoperable, a certified adapter can be used with a non-Quick Charge 2.0 device, though the fast charging benefits of Quick Charge 2.0 will not be available. "

By all appearances, Motorola's "TurboPower™ Charging" is nothing more than Qualcomm Quick Charge 2.0. (That's what Snapdragon 808 in the XT1575 uses.)
The third-party Qualcomm Quick Charge 2.0 chargers I bought are recognized as "Turbo" and function with the XT1575, just like the Motorola charger that came with the XT1575.
(There are a LOT of Qualcomm-certified QC 2.0 chargers for sale by third-party names. Qualcomm has been BUSY. )
To slow charge a S7, do we have to turn off fast charging from the settings and then charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?
Does this hold true for Motorola's phone also which have turbo charging option?
Also how to measure battery cycles? Any credible app for the same?

Moto doesn't have the option in settings, it uses industry standard Qualcomm Quick Charge standard rather than a OS hack like Samsung (no offense)... If it is connected to a QC 2.0 charger, it will negotiate the appropriate charge rate, if it is connected to a "standard" charger it will charge normally.
I don't think you can accurately measure battery/charge cycles... even if you could it would be extremely deceiving, what would be considered a cycle? Charging at 50%, 30%, 10%, and to what point 75%, 80%, 100%? Too much room for interpretation here that could be swayed either way depending on the person/app counting it's point of view.

Thanks for replying dear. So, for S7 I have turned off fast charge, should I now charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?
For Moto G, the question is the same as above.
Of the little what I have understood from various threads here is to charge the battery when it is between 20-40% to 80-90% if you want to have a good battery life. I used to do the complete opposite charge, when the battery is at say 6-7% and charge it till it is maxed. I used to do the same for my laptop, any other tip for the battery?
And I have signed your petition Brother. I hope they listen to the users.

Does Fast Charge hurt the battery life, no, at least not directly... heat does. Using an older style charger will avoid Quick Charging but I think that foregoing that benefit for a few more days of battery life is hardly worth it. I frequently have 30-60 minutes to charge, not 3-5 hours, so quick charge is nice, if it takes few days off the longevity of the battery so be it. Those who think it cuts the battery life by 20, 30, even 50% are wrong, that simply isn't the case because of Fast Charge itself.
The Moto G isn't an issue here, it doesn't support Quick Charge until the 4th generation, but why give up the feature?
I don't think the "rules" of charging apply as much as people think they do... I charge mine overnight and whenever it needs it during the day, if it does. There is no need to do anything special.

Thanks for the wonderful and detailed reply. I am going to try, not stick, to slow charging to see the difference in heating of the battery. My SIII's charger 's input is 150-300VAC, 50-60 hz 0.15AA, output- 5.0V-1.0A and S7's details are input 100-240V 50-60hz 0.5A, output- 9.0V= 1.67 A or 5.0V=2.0A. Can I use the S3's charger to charge S7 after turning of fast charge or is there a voltage difference or something? G4 is at home, don't know about its details. Also in my country the battery or the replacement parts are way too expensive.
