Hello,
I'd like to build an AA-battery pack for loading my diamond on the go. (I know there are LiIo-packages on the market with high capacity, but I prefer standard AA-cells)
I've built one for my Loox 720 a few years ago but had the problem, that loading was terminated after the voltage of the package dropped slightly below 5V. It is not so easy to build a package with a standard voltage-converter because of voltage-dropping with too few cells or heat-production with too much cells.
But perhaps the diamond continues loading, even when the voltage drops by - for example 1V, so this would not be an issue anymore.
Sadly, I'am not a specialist on this things and even if the Diamond can handle lower voltage I'am not sure if it can probably do harm to the LiIon-Battery or the electronics within the diamond - don't know, if this is possible with too low voltages.
Perhaps somenone can help - I think a working AA-package for the diamond could be of interrest for other users.
Many thanks in advance!

Take a look at the USB Charging Spec - available here - it clearly defines the operating limits that devices (and chargers) should comply with.
In your case your device would be acting as a dedicated charger (you should put a 200ohmn resistor across the data lines to tell the Diamond that's what you are) and so you should aim for >4.75v for charging currents <0.5A and >2.0v for currents >0.5A. The Diamond will control the current draw and given you're using a battery you have no control over the stability of the minimum voltage - the voltage/capacity curve will be dependent on the type of battery.
Assuming the Diamond is compliant with this spec then it be happy working within the above tolerances. Indeed, in practice you may find it will work beyond them (the charging is controlled within the device hence it can refuse to charge if it is out of spec).

Many thanks Mathew! This sounds good - if I've understood you correctly I can use lower voltage with batteries able to output high currents. Even "normal" AA-cells should be able to output much more than 0,5A - this seems to be only relevant for USB-ports, so I should be able to go as low as 2V and I'am out of problems. In this case I even not have to build an adapter by myself but can use any cheap "emergency-loader" from shops. (If the resistor should be neccessary, I can add it to the package)
Do you mean, the shop-packages have this resistor built in allready, and can it be dangerous for the device without it?
p.s.: Sorry - I've allways said "loader" - I mean "charger", of course.

In theory, yes, at least to stay within spec. However, the Diamond might not be as tolerant as the spec demands/allows so it's more a case of suck it and see.

For the spec, yes (although I'm not sure what you mean about USB ports - you are one as far as the Diamond is concerned) however the Diamond battery is 3.7v and, assuming no DC-DC converter, you'll have to stay above that to get any decent rate of charge.
If you are using alkaline batteries then you pay the price with a sloping discharge curve - the voltage drops almost linearly with consumption. This is why lithium batteries are being used in such charger packs because their voltage remains relatively flat and they have a high capacity. Rechargeable NiMH cells would also be a good choice, particularly at higher charging currents.
Edit: They say a picture speaks a thousand words - here are some discharge curves so you can see for yourself.

To be honest I'd just buy a ready-made one anyway! Ideally one with a voltage regulator inside it so you can load it with practically any batteries you like.

Yes of course - in this case it is the wisest thing to do - particulary for me.
The reason for me to build my own one for the loox was, that the stock one did not work, (or only for a few minutes, because the loox seems to be very pedantic with the voltage). I have to admit that my own one did not worked too, cause of to much heat-production of the converter.
Seems to be a lot easier with the diamond.
Thanks again!
Why not strip down a car charger and add a few AA cells, all the electronics are already there, I'm pretty sure you could use a variety of old phone car chargers, why not check your drawers.

If the diamond really accepts voltages between 3,6 and 5V a car-charger is not neccessary and very ineffective. A pack with 4*AA NIMH would be enough.
Regarding my Loox: I would need at least 10*AA, about 6 of them only to feed the charger. And the problem with voltage-drop is not solved.
How efficient is the charging process? I mean if you charge a 900mah lion battery with a 1.5ah nimh battery will it do it, I thought about 90% of the energy you put in is lost in the internal chemistry, which wouldn't give you more than about a 15% charge.

Good NIMH-batteries have 2000mAh or more. If you use a LiIon-charger you have the same probs with internal chemistry. If one would loose 90%, no one would by any type of external charger. If you mean the chemistry of the AA's, no one would buy AA's anymore.
With a 2000mAh AA-pack, I think you get about the same charging-result as with a 2000mAh LiIon-charger. But you can put into the AA-pack batterys out of any supermarket in the world.

And get what charge% from 0 could you get?, I'm suggesting you would need heavier duty D cells or more to get a full charge, you don't get out anywhere near what you put in.

Youre right, of course - it's not very effective, but not (or not much) less effective than a same size LiIon-package. Probably its only a personal habbit of me to prefere AA-cells. My first PDA was a Psion 3c, the second a Palm-derivate. I liked it very much, to be able to put any AA-cells into this devices.
Most effective way is to swap the device-battery - its my oppinion too. But as long as you can't find LiIon-packs in differnt standard-formats for every device everywhere and they are not building wall-plugs into trees, I find it somewhat nice to have the ability to use AA's or A's.
LiIon have better charging/dicharging-capabilitys and are lighter and smaller, but this does not mean normal standard-cells are totaly crap in comparison, they have developed too.
I would recommend it, when not every device on the market would use LiIon-Batts, perhaps even not swappable - not every device has to be ultra light and ultra small, for me it does not matter so much, if an external charger is somewhat bigger and heavier, if it gives me much more flexibility and is cheaper in long-term usage.
This is for kernel devs only. The patch itself is useless to those who do not/can not compile their own kernel.
This patch allows one to force AC or USB charging for any charger. It also provides additional security when connecting to public charging stations because with either force AC or force USB mode on, USB transfers are disabled, protecting your data.
Fast charge can be toggled by issuing:
echo 1 > /sys/kernel/fast_charge/force_charge_mode
Slow charge:
echo 2 > /sys/kernel/fast_charge/force_charge_mode
and off:
echo 0 > /sys/kernel/fast_charge/force_charge_mode
Plug your phone into the charger AFTER toggling the desired mode.
In addition I have created a toggle fast charge widget that may be used to toggle fast/slow charge on and off right from your home screen:
https://play.google.com/store/apps/details?id=com.incredicontrol.fastchargewidget
I have not yet implemented the three way toggle into incredicontrol (free), but I will be. I have to change it to support slow charge also and haven't yet gotten the chance to. I will be implementing it when I get the chance though so you guys have a convenient free way to toggle also.
For the widget (or any fast/slow charge toggle) to work, you MUST be running a kernel that has this patch implemented.
As a good gesture to support a fellow dev, I ask that if you implement the patch into your kernel, please link to my widget as one means to toggle it. You are of course free to provide other ways to toggle it as well if you so desire.
Kernel devs, if you would like to test the widget yourself to confirm its working, and for convenience of testing, please contact me and I will provide you with a copy. You must show that you are a kernel dev though (i.e. link me to your kernel post so I can match your username).
Good luck have fun!

Here is the neoblaze kernel (stock froyo/gb, not AOSP) patched with the mod so that you guys can test. I will not be supporting anything regarding this kernel except the charging mod itself!

Its not necessarily just for car chargers, that's just the easiest example. It can be used with any charger that is detected as USB. Some powered hubs for example can easily put out 1A but would still be limited to 500mA by the phone. The patch will allow you to toggle force AC mode on/off via an app or widget.
Ya i got that but the only usb-charger besides the outlet that i use is my laptop, and i use it only for transferring files. still a great idea!
In other words. If you will be using USB port and cable as current source, The specification asks for Data + and - to be shortcut. And normally phone detects it and also the fifth sense pin and then high current charging must kick in. (although our LG phone uses also it to enter download mode)
If you use the widget and enable high current charging, you'll fry out your motherboards USB port probably...
Another warning. If someone has read about Lithium Cell charging methods AVR based documentation for example. Such high current charging decreases your battery cycle life. So consider those facts first of all!
And those with car chargers... especially cheap ones... in most of these devices are SMD LM317 or LM7805 etc family inside... it will dissipate [email protected]=7W so these sticks will fry out and also blow up despite it can deliver 1.5A - the catch is with proper heat sink.
So So So... dear coders... consult your hardware guys before acting for the good deeds... the cons are more than the gain.

Absolutely not. It would have no negative effects on your battery at all as the current isn't increased beyond what it is for AC charging.
Also you notice nowhere that my recommendations were for using it to charge from a motherboard. Despite that, the current pulled from the board is ultimately limited to the fuse at the port. Even if a device successfully tries to pull more than the board can provide (which the board won't put out anyway), the PPTC will cut off power to the device.
So So dear hardware guys, please read before jumping all over someone.

Then please why I have to repair broken motherboards that Ipad2 have fried a lot? Why? Because they are cheap mate, and fuse is the last resort. And No current limitations aren't implemented there...
I said once again. This 0.5A setting is the most green one, as many manufacturer use as a law!
The fact that some make a PR and tell our device charges faster doesn't overthrow simple chemistry and physics. Ok it will work. Charging the cell with higher current, raises temps and other chemical emissions and it deteriorates faster! So the philosophy is simple for them, the user will kill its battery faster in order to buy a new phone eh? Nice!

I agree with you that it shouldn't be used to charge from a motherboard, although many have taken the risk without issues.
Essentially it is a software version of the charging cables with bridged data lines ("charge only") that many buy and have no issues with. I'm just bridging the data lines in software so to speak. The current draw is never increased beyond the phone's spec. The most important thing is that the end user knows the source they are drawing from is capable of providing the current.
I do appreciate your concern for the community and desire to educate everyone. We need more people like you around.
So with that, each individual can make an informed decision on their own. If anyone is still interested in the mod, shoot me a PM if you want to test.
Yup, there isn't much math to be done here.
Higher current means higher temps, and O2X already has trouble with temps as it is.
However, to each his own, and as long as people are aware of what they're doing there is no such thing as too many options... although me personally I would stay away from this one.
EDIT: Wait... so you're saying that O2X charges at 1A when connected to a wall charger and at 0.5A when connected with USB? I get the point now. So you only risk damaging the motherboard, and not the phone.
I'm guessing it would be more interesting for O2X users to do the opposite! A 'Force USB charging' because from what I see a lot of people get SoD while charging their phones overnight and this might fix it
What do you say Chad? Would you be interested in implementing this feature? I think I would use it!

For so many years of using rechargeable batteries, I haven't been a fan of post-purchase "fast charging". But then again, I live in a tropical countries so non-air-conditioned room temperatures come quite warm (especially since we're entering summer now).
I must say that I love the "force USB charging" idea though. I rarely get those, but, it's another troubleshooting possibility for the many users encountering charging/overheating BSODs.

also if you charge the battery faster the battery life will be worse then if you charge it slow
so fast and a bit worse battery life
or fast it slow and a bit better life
you can really feel those difference if you live in a country where it is quite hot

charge one day using wall charger and charge next day using computer usb you will feel the difference

Jep Owain is right... I remember old times at my work 6 years ago Nokia 8800 (RM-13), it had a tiny battery and it was the time when chargers changed from impulse type from transformer core types... so with the older slow charger the battery held for 15-30% more. (I suppose the battery is hot, and then the voltage is also artificially higher and in reality it isn't charged to its maximum).
But as I said, don't overdose with it especially with car chargers and motherboards. The phone will be fine. Battery should be changed after a year anyway... it costs for me $10 anyway...

Lucky guy. The O2X battery costs roughly US$ 30 here.
So you guys are saying you get an SoD if you charge overnight on AC, but not on USB?
Reading through the battery driver it looks to me that if the battery gets too hot, it swiches to USB charge current, if it continues to be too hot, the charger turns off so I wonder if your issue is somewhere else. Anyone try to record a log (cat /proc/kmsg > /sdcard/kmsg) overnight and see if you get any messages along the lines of:
[OVERHEAT]: Change Charger setting to USB mode
or
[OVERHEAT]: Deactive Charger
Hi Guys,
Anyone tried Solar Powered Battery Chargers?
Looking at this one here :

I'm looking fior the same. I bought recantly GOAL ZERO Nomad -7. Instead of charging it drains the power of my Note-2. I guess it is because of the non-standard pin-out (11 pins), so this is the one I would definitely not recommend.

I haven't seen any positive reviews about any solar powered chargers. The problem is that you need to apply voltage (bias it) in order for it to work. Like those solar power panels on the roof of people - if you loose a power to the house, they will not work So they might be draining instead of charging lol!!!
Don't know for sure how it works and if it works and how efficiently. So if anybody has any real life experience, please chime in. Most of the big name external battery vendors don't want to carry this product. I only seen it on ebay and Aliexpress.
I personally haven't tried one. From what I've seen about them, they're very fast, and can be nick-picky about the angle to the sun. On top of it, you'll probably need to check what's the output versus what the phone needs to change.
I think you're probably better off finding some kind of crank mechanism and use that to change the phone. Plus, you'll get a little work out too; you'll live longer to enjoy your phone, 8)
I have a voltaic that I use when camping or on extended hikes. It comes with a 3000mah battery. I haven't used it on the Note2 yet, but used it a lot with my Fascinate. The battery works fine as backup power, though it charges slowly and the phone pretty much has to be off for it to be effective. It takes most of a day of full sun to recharge the contained battery. It's ok if you're going to be away from power for a week, but for less than that I think just an extra battery or two fully charged would work better.
I think we just need to find or build one that supports 2.1 amps (ideally) but anything over 1amp should do something.

I have one I found at Best Buy a couple years ago. It's a single amp box, so charges my Note II very slowly. I've used it on my bike when I'm out on rides. I have a mount for it and my phone. While riding, I use bluetooth headphones. It does work, but like someone else said, there needs to be one with 2.1 amps.
I as well have a Nomad 7, but mine charges my note without issue, although I will admit, it is impractically slow.
I bought this couple of months ago, charging the phone is a wii bit slow but it works like a champ!

WICKED... just stumbled across this on ebay. If you are a roll your own DIY type and want to charge a rapid charge device like Note2 or a tablet or something, this might be a great thing to look at.
http://www.ebay.com/itm/DC-DC-5V-36...018?pt=LH_DefaultDomain_0&hash=item2c700c47c2
I, personally, don't like the mini-usb connector... seems kind of goofy. I'd prefer just two wire terminals to connect solar panels to.
But yeah, if you've got high voltage solar setup... e.g. anything between 5V and 36V and want to have a clean, regulated 5V usb compliant output, this would likely be your guy. I'd also want to make sure it really does work with note2 - in terms of negotiation of currents higher than 100ma. YMMV FWIW
AND if you don't need note2/tablet 2A...
this guy seems like about the right fit.

Nokias wireless charger works with all phones that have NFC, looks like i will be buying that then!
From what I've seen wireless charging is presently a bit dodgy anyway, perhaps Sony are just waiting for the tech to settle down a bit before introducing it. I don't think I'll be going for wireless charging with my N4 any time soon.

I don't think so. It has NFC so that you can launch a task when you put your phone to charge, but it's still based on the Qi wireless charging spec which means the phone has to be compatible too.

For one you have to pay upwards of $25-$50 for a wireless charging pad, charging takes several times longer, the phone/battery get hot while using it, which will probably lead to shortened battery life, and it's not like you can use your phone while wireless charging since if it moves more than a few millimeters off the pad it stops, versus wired where you are limited only to the length of the wire.
Isnt wireless charging jsut putting the phone on a "dock"? Like my cordless phone? or the old nokia's where u had to put it on a charging dock? Ppl behave as those it is sending microwaves to your phone within a certain radius and the phone magically charges...and if it were like that I would be afraid of nuking my insides lol

Exactly my thought. It's wireless, but you have to put your phone on a mat... i really prefer putting my phone on a dock, and the one for Xperia Z is very good because there is no "port" that might go loose with time, just two metal pins that are touching the charger pins.
For those in doubt - here is the dock Sony will release to go with this phone - Not quite wireless charging but nearly. Having seen this it has convinced me to get the phone - the thought of fiddling with the port covers in the dark every night to conect the charger was putting me off (my gf goes to bed before me so I can't put the light on).

Price is supposed to be ~35£. Could be cheaper, but it's not that bad.
Hello,
My LG G2 charging cable seems to not be working anymore.
I also have a bunch of random chargers/cords (some in better repair than others). Does anyone know a relatively cheap plug/cable to buy?
I'd like to just buy 5 or 6 of them to have and just have a standard one in the house, since I have 3 Nexus 7 tablets, 3 phones and various other things that charge with Micro USB.
Thanks!

It'll charge two devices at about 1.6A or so, one at around 1A, the rest around 800mA, not sure about total real-world current if you're charging a bunch of devices at once.
But for me, it's perfect. I'm usually just topping off my G2 and Nexus 7 as I go to bed, and have other cords dangling out for my kids Nook Color, wifes Nook Touch, etc etc.

That's not bad, I wish it was just all Android, instead of apple and android.
Is there a particular cable that works best for charging?

Nah don't worry about the crapple part of it, every port on it will charge at the "rated" speed with a normal USB cable on an Android device. In reality, it's about 80% rated from what I've seen, so like the 2.1 I've seen 1.7 out of, but that's not bad. I've charged my OG Note, LG G2, Nexus 7 2012 etc, all charge fine. Not as fast as their stock chargers, but the G2 charges at 1.5-1.7A so it's more than fast enough.
No special cable needed, you don't need a "charging" cable for sure. But there's a whole thread about the best cables to use for the G2. It's very picky about voltage sag, and cheap or very long cables it will drop down to a slower charge regardless of how much power the charger can provide. You might look at that thread (http://forum.xda-developers.com/showthread.php?t=2460881) if you're having specific issues or want to pick up a specific cable.
I haven't had any cable problems myself, except for connectors being too loose or too tight (G2 connector is weird).
BTW, I've been watching the last few days, and this charger does output higher output, it's just the G2 is kind of weird.. It'll ramp up and down what current it'd drawing, or something.. Like 1800 one second, then 1000, then 1200, then 1600, etc.. I realize that the reading has whatever the device is using removed from it (2000 in, 200 used = 1800 reading) but the G2 uses like 20mA idle, so..
Anyway.. I've seen as high as 1960mA according to Android Tuner.
I just bought a Belkin from Wal-Mart for $20 and its output is 2.1 amps my phone charges fast!
