We (noordwyk & Me) managed to put together a Portable Charger for the Diamond. I have attached some pics:
noordwyk will soon post the diagram
Sounds cool anychance of some more info: Like what you used and a diagram to show how it's wired? Please.
When i get time I shall upload a graph
For everyone without soldering skills - there are plenty of portable external chargers for sale, even one from HTC:
HTC Battery Bank BB G300
i've bought a couple of portable chargers. Neither of them worked. In bothe cases i plugged them in and my diamond showed itself as being connected to a power source on the task bar. The light ring pulsed in the charge pattern also. However after a few minutes of "charging" once removed the battery level is lower than when i plugged it in. This is the case whether i had the diamond on or off when charging. Chargers work fine using different adaptors on other none wm phones. The thought i had was that the chargers were outputting enough to power the charging circuit but not enough to charge. This in turn is draining the battery. any thoughts ppl??

Portable chargers and HTC don't go together. You MUST switch your phone off to charge it otherwise the PMS will get confused and keep changing power sources like External > Internal > External > Internal and so on. Just like a light switch when you turn it on it takes more power than just leaving it on for 10 minutes. Portable chargers have a charge rate of ~250 mA which is 1/4 of a Official HTC Charger.
Conclusion: If you want to use a portable charger ONLY use it after turning your phone off otherwise its USeLESS

Is it the same for car chargers ? If so, how can we power the device for, say, using GPS navigation for long trips ?

Nope! Car Chargers work well. I use one regularly - specifically for the reason you mentioned- usage of GPS while on long trips.

Basically what i thought then. I must be getting particularly rubbish ones because they dont even work when the phone is off. I gave up on them a few months ago and just bought a spare battery and charger. Quite cheap off ebay and a battery is a smaller item to carry than a portable charger.

I would be quite interested to see a wiring diagram of this too, it'd be great to be able to just grab a 9v and charge up on the run...

Well its true in the UK
Shouldn't be too hard to build. Take one of these (high efficiency!), solder the 9V battery adapter and the mini-usb cable to it and your're done. Only thing I worry about is the capacity. You get NiMH 9V cells at approx 250 mAh. Given the battery voltage is 9V, you get a total energy of 8.1 kJ stored in it, which translates to 450 mAh at 5V (input voltage of device). Given that this back-of-the-envelope calculation does not take conversion losses in account, you can be happy if you get 20-30% charge out of it. Maybe you could wire several 9V batteries in parallel so you get more charge out of it. Which I am gonna try out right away .

No. MythBusters tried it out. Turning on an incandescent light bulb (60W I think?) uses about the same power as leaving it on for 17 seconds. Fluorescent light bulbs didn't use significantly more power to turn on.

Ok...
The only problem is that my Diamond seems to use more power than what is provided by the car charger... So the car charger limits the discharge, but that's all.
On my old prophet, I could have used GPS for days (using a bluetooth external GPS of course).
It's a pity the diamond is not as power efficient.

I agree with you. A fellow XDA member posted somewhere here that he started of with 100% for a 6 Hour journey using his diamond and when he got to his destination he said it was around 30% left!
It's not too hard to build one, as soon as I remember, it's adapter (for the battery), 5V regulator and a female USB (it's easier to find, you use your sync cable and you can charge other things, MP3 players, portable speakers etc.).
Am I right, or you have different design.
Also, you can use 4 1.5V batteries, I've got few 1900mAh of them, so they should last longer. Also, I think the regular 9V battery is bigger than 250mAh.
Well i soon will be updating my E42M website with this years invetions so visit it when you can

Came from a TP2 and I could charge via USB at around 900 mA using fast charge driver.
Since I am a complete Android n00b, and an EVO n00b I have two questions.
1. Are there any apps out there that can show you how fast the battery is charging and discharging? I had one called Battery Monitor in WM, and I want an Android version of that.
2. It appears that USB charging is quite slow. Can anyone confirm the speed at which this phone charges via a USB port?
3. Is there a way to make this faster?
TIA!!

A 2. Not sure, shouldn't be too long, how long is it taking yours?

Thanks...Not sure how long it takes as I havent had the phone too long. I know while plugged into my computer last night it wouldn't charge very well.
Computers have much lower power than a wall socket. If you want to charge the EVO fast use the wall plug. Anyone who uses a Mac and the wired keyboard should know what I am talking about.

Every computer I owned charged my TP2 at around 800-900 mA as long as the fast charge driver was on the phone.
So I know for a fact that it's possible. It's limited by the phone, not the USB port. Appreciate the reply, but did you read Negrito's link?
And Negrito, I did search... This forum.... No hits. I see the link you provided was in the Hero forum. I didn't realize that the fast charge USB issue was affecting other Android phones as this is my first.

My bad broseph, totally forgot im still subscribed to Hero threads. I just switched to the Evo Launch day.
Its not really an issue per se as that's how all phones normally operate. On WinMo we just got spoiled my No2Chems hack. Anyone know if No2Chem made the jump to Android?
I have seen a lot of familiar names on the Evo forum, like OMJ, and Caulkin!!! I cant wait until someone comes up with an untethered root option and how to bypass the NAND cause I know the ROMs are just going to be simply amazing.
Was digging around in the custom menus, can't remember which one, but one of the ones that you type ##numbers# and enter your MSL and there was a check box for USB charging. Mine was unchecked for some reason. I left it alone but wonder if that makes a difference?
I've tested a few charging scenarios and can tell you that using a wall charger that outputs 1000 ma will help speed up the charge.
These from Monoprice work very well:
http://www.monoprice.com/products/product.asp?c_id=103&cp_id=10311&cs_id=1031106&p_id=6767&seq=1&format=2
want the same thing for the car?
try this one.
Here's the link to a micro usb cable at monoprice for $1.20.
There's a nice Rosewill 4 port charger, that will output 2000 ma IF you have only one device plugged in. With two devices plugged in, it falls back to 1000 ma (still really good). I have this in the kitchen for the kids to jack their various usb things in for charging.
The thing to remember is that the phone will pull as much as it can (most recent phones can pull between 750 and 1000 ma.) What will cause it to charge slower is not usually a software setting, it's having a port that will only put out 500 ma or less...which is what many computers output.
Sean
there is an option in settings /devolopment for usb charging doesnt ssy what it does though
I don't think mine has taken more than 4-5 hours to fully charge and signal strength isn't the greatest at my house so that probably has an impact on it as well... I've no idea if that's normal for a smartphone or if it's considered slow, I don't think my Sony Ericsson feature phone was any faster but the battery indicator on that thing was wildly inaccurate anyway.
My EVO seems to charge just as fast w/the included HTC adapter as with a generic Philips one I had, as well as one of those retractable cables. I was afraid that cable wouldn't be very well shielded and it wouldn't charge right but it seems fine, I'll only be using it when I travel anyway.

I could charge my Touch Pro 2 in about an hour or two using a standard usb plug on any computer I owned.
Might I add the Touch Pro 2 and the EVO share the same identical battery. The EVO obviously draws more current..... I found while using my EVO while plugged into a computer, it barely charges at all. My guess is its discharging while charging at a very similar rate.
Contrary to what most of you are saying, the ma rating of the charger really makes no difference as the phone (and prior htc phones) will pull <500ma if they detect they are plugged into a computer or non-official charger and 1a if they detect an htc charger (which can even damage 500ma chargers). The way this is detected is through grounding of one of the microusb pins in the official charger (and indeed many generic chargers but not all will be detected this way). Absent this grounding (I forget which pin), it will charge at a slower speed. I know of cheap 500ma chargers which have been caused to smoke by attaching a cable with that grounding fooling the phone into thinking it is an oem charger. Many chargers labeled 1a will charge at the 500ma rate as well.
Also, modern computers are fully capable of outputting 1a of power through the usb port. While the spec indeed is 500ma, with a proper cable (or the fastcharge driver for windows mobile), you can force a 1a power draw without any issues. Cheap usb hubs or cheap usb power ports may run into issues.
I'd love to see a solution for android but I don't think one exists.
Actually the HTC battery Widget will show you if you are on AC (1A) or USB (500ma) charge. You can get this widget from the market (not sure why it is not included in the phone in the first place).
I think that the grounding pin is likely the trick and I will be searching the web to see if I can locate it. I have an older battery pack from APC that can output 1.6A but the only way to get the EVO to charge as if it was on "AC" is to use the HTC plug, and then quickly, before the charge light goes out switch to my alternate source. This seems to trick the EVO into thinking that it is still plugged in to the official charger.
This is of course trickier with my car charger, which has been very frustrating - using the phone for navigation and plugged in via usb usually has the battery draining rather than charging!
I wish there was an easy way to fix this, my old phones always attempted to pull as much current as they needed.
My friend uses a 2A charger for his HTC touch pro 2, and it uses the same battery as the EVO if u guys didnt know.
i havent tried it on my evo, but being its from htc too (and uses the same battery)... id expect it to work with that much current.
I currently use a 900mA one in my car, and i do notice that if i use something less than that i tend to get feedback from the audio jack that connects to my cassette player
Found a discussion on this on the android forums relating to the HTC Desire:
<Too new of a user, system won't let me post the link>
I opened a car charger and shorted pins 2 and 3, and the phone did show charging over AC (2 and 3 are the data pins, 1 & 2 are power). My multimeter was acting up, so I am not sure whether the EVO is actually pulling more current - it does appear to be charging faster.
If you try this make sure of 2 things:
1. You charger is capable of 1A.
2. If you choose to short the pins on a USB cable make sure this cable never gets plugged in to your PC.

For your Q #1 search the market for Battery Indicator, great simple app that gives you a battery percentage and how long you have been plugged in or unplugged.
OK.
I have read the Accessories Posts, but didnt found an Solution for this.
I own an 5000mah Power Bank with USB Connectors.
Output 1A.
So, as you Guys know, if i connect such Device via USB-Data Cable it is detected by Tab as "PC-connected" and the Tab does not charge. If Tab is off, it charges quick and i am able to charge it with one Power Bank Load 1 1/2 Time.
And with my Galaxy S it works also if the Phone is on.
So my Question.
Is there any Tweak, Trick or Mod to enable the Tab to Charge it this Way?
Is it possible to modify some System settings to bring it work?
Have you checked in settings, if the battery charge doesn't go up?
It will charge using any current (even 300mA) only slower. The icon on the battery just says "I'm not connected to my proper charger", not "I'm not charging".
On JM6 and JMA the icon is also a bit better and show's it's charging but not full speed But charge rate is same as before.

Yes.
I am also using Battery Pro that displays me an Icon with Battery Load in Percent.
But the Tab doesnt charge.
Load of Akku decreases.
Yes. (Having JMA) the Stock Icon displays that an Power source is connected but still doesnt charge at all.
My Hope was, that anyone with Programming/Coding Skills is able to bring the Charging to work.
I am not nearly able to do this
I find it absolutely bad, that Samsung has made this incision to the usability of the Tab.
On my Galaxy S i can change with the same Power Bank in Operation without any Problems.
Very Pity that the Tab does not

Hi Pbruck, which power pack are you using & what's the specification for it. can you provide me with the model no.? Thank you.
Hi,
i use this:

Sorry, but have only found it in this German Shop.
Maybe you can still use the provided Informations there.

It says "1A (2x usb)" so you need to use 2 ports to get to the 1A.
There is no programming or modding necessary, the tab charges from anything that is powerfull enough and your crappy cheap charger is not (im just teasing you cause i ordered things from pearl before and all they sell is junk).
I just received my stash of charging gear for my Optimus 7 today, bought from DX. Having read everywhere that USB chargers are 5V +/- 10%, and seeing that the original LG charger outputs 4.8V, I thought my purchase was ok and that this charger would work.
Turns out it doesn't. When I connect the phone to the charger via USB, I lose control of the touchscreen and the system gains a mind of its own. I literally just hold my phone in my hand and stare while it randomly enters hubs and either opens an email message or dials someone. The physical buttons still respond correctly, and it's not until I disconnect the charger from the wall socket or the phone from the USB cable that I can regain control of the phone. My guess is it's a hardware fault and not software.
Granted this unofficial charger cost me around $1, but I got some similar 5V car chargers to go with it, and I've never had problems with other USB chargers.
Unofficial charger specs:
Input: 100-240V 0.15A (0.15A) 50-60hz
Output: 5V 1A
Does someone else have this issue? Is the Optimus 7 an uncommon device for requiring 4.8V input instead of 5V?
Your problem is NOT the charger, as that has nothing to do with the functions of the phone.
Your problem is that your LG Optimus 7 E900 is a DEMO unit, with a DEMO ROM. And until you flash a stock ROM onto your phone, you will experience the demo played out while connected to a power source.
You sure? Because I tried it with the 5V 1A car adapters and no problem, and the original 4.8V 1A charger gives me no problems either.
How do I check my ROM version? Firmware is 1.0.7.10, OS is 7.0.7008.0 after the February update.
Can you get us video on this?
Please excuse the ****ty video quality
That is most fascinating. I recommend you stop using that charger on your phone
So, obviously, you do NOT have the demo ROM as I suspected initially.
Since you say it works with another 5V 1A charger, then I think this specific charger may be sending unexpected, random data signals down the USB cable, resulting in the unresponsive and bizarre behaviour. Since the original charger works well, and charges pretty fast, just stick with that for now.
At least you got the update, here in Canada, we are still waiting for our first update.
And your English is so good, and without any accents...Are you sure you aren't from our here (North America)?
This is true magic Really I have no eplanation on this problem. It is only 0,2V
Yeah, and there I was thinking that the whole point of USB charging is that it's universal and totally compatible, no matter what adapter you buy and what cable you use, provided it connects well.
It seems this is not the case, and I'm weary of trying another third party USB charger, as I still cannot tell if this phenomenon is unique to the Optimus 7 or not. Sadly, the only other MicroUSB phones I have lying around don't actually support charging via this port, just data transfer.
i also admit that im "dazzled" by ur -smart-phone...
probably that adapter is"magical" somehow... did u try it on another phone??
+i also use different chargers but never had any abnormalities so far..
Though i use the original chargers that came with my blackberry 9700 and htc-desire, and just checked the blackberry output is 5v!! i cant read the htc...
So, probably that adapter of yours is a "mutant from another place"...
confirm, htc is also 5v...
ps2- i'm also on 7008, and havent got any issues with charging on both 7004 and 7008
The problem is in the charger, it's too chinese . I had this issue with other touchscreen phones, like SE X8, X10... Just change the charger, obviously it has some hum/noise...
lol...
too chinese? lol
im having the same issue when i use the lg power adapter.. it doesnt always happen but when it happen the touch screen just when berserk.
i always thought that it happens on all units. uh oh
To be honest, I thought you were crazy till I bought a Chinese adapter as well. Don't know the voltage, but I'll check it tomorrow. I think it might have to do with the way the unit is shielded, or not. The only time I wiggs out is when I leave it on the desk, but as soon as I pick it up and pull it a few inches away form the desk or any other object it works fine. But as soon as I put it back down, the screen does the same thing.
I have a usb plug that I plug into the computer that didn't do that at the same desk, I'm going to bring in my other charger and see if it rule out the outlet / interference or just the cheap a$$ adapter....
The only part that worries me, and the only reason I might stop using it, is it takes a bit from the time I unplug it to the time the phone realizes it's unplugged and the charging icon stops. Which doesn't happen with any other charger.
I had this problem too.. until I realized it affected my other touch screen devices too (Galaxy S, Galaxy Tab)... Turns out the 5V charger was the problem. Replaced it with a 5V charger of Philips/Belkin/Samsung/LG and all worked..
The unbranded 5V chargers don't work well with capacitive screens as they seem to be letting off some extra current.
When the phone is charging, and i try to use touch, i notice the input is jittery- try pulling down the notification bar on the top, and holding it half way down the screen and looking closely. Scroll with lists and hold your finger in once place - does the list jump around slightly?
Is it just me or everyone?
Maybe I should not use my blackberry charger at work! I will test with the samsung charger at home (the output voltage is the same as the samsung so it shouldnt matter!)
I feel you man! Had the exact same problem with the original Galaxy (i7500) - my unofficial charger made it impossible to type anything: heavy jitter.
Ccl: find a charger with the exact same specs...or just use the official one / or usb cable.
No problems here. typing this using swype While charging and its faultless!
Sent from my GT-I9100 using XDA App
Well it's better than my Desire which gives you a static charge or electric leak somewhere when charging and you touch the metal bezel.
i read something about this issue in the user manual, the PDF one somewhere in this forum
look it up, and read the battery or charging section
Have the same exact problem with my Original Galaxy S when using a "not-samsung" micro USB charger, with the obvious difference that my screen became completely unusable not just "jittery", it didn't respond to any touch when charging it with that charger.
Use official charger and it'll be fine !
Yup it is mentioned in the user manual, it said the touch screen may not function well due to an unstable power supply. I guess it applies to all touch screen phones.
thanks for the input guys and hopefully this will clear it up for anyone else confused by this.
Last question - am I damaging my phone by charging it on my blackberry charger?
Only one I have at work which is why I ask,
Thanks.
While I cannot confirm whether it will damage the SGS II or not, I can certainly say that when I used to use BB Chargers to charge my Motorola Razr among others that were Mini USB, they ended up ruining the battery life and giving me false readings about the percentage left.
Personaly I would not take the risk for my beloved 600€-phone

I dont know - I just tested and the same thing happens with my old Samsung Galaxy S 1 charger . hmm.
(my phone works just fine.(only while charging via pc). it does jitter when you charge it through mains.
voltage converter?
Since I live in the US and ordered a UK model, will i need a voltage converter + plug adapter for my charger or will a simple plug adapter work just fine?
This phone has capacitative touch screen, and I believe this works on the principle of changes in electric field upon bringing a conductor(read "finger") near the charged display. I suppose during the charging process the leaked current is interfering with this electric field causing those above mentioned problems. Might be substandard charging adapters?
Same problem on my Dell Streak! A good thing to test it is Swype! The line your finger makes when typing goes all over the place!
