Hi Athena owners and gurus ,
I have an external battery / portable power pack - etitech model : 3s5p-L01 ( www.etitech.com.my ) input : 16 - 24VDC, 75 w and output : 14 - 24VDC ( Auto adaptable ) , complete with a cable , I wanted it to modify it's cable into a mini usb end to fit into my dopod u1000 , but i think i need a power down adapter put it in between this power pack and u1000 before i can use - right ? I dont know how much mah this battery pack is but it is suitable to power up my IBM R60 laptop for at least 2 to 3 hours of usage . I was thinking if can modify to use with my u1000 , imagine the maximum hours i can use with one full charge and to use it when travelling for let's say a week of usage . Please anyone can suggest to me on how can i use this ext. battery pack with my u1000 because i really need this to work and it will be good thing to multiple use this for many devices besides my Ibm , Thanks and best regards , cheers - jimmunsw
Dear All athena owners ,
YeeeHaaaaaa ! I have managed to mod my external power pack to power up all my u1000 and other devices , here's how :-
My external lithium ion battery pack - i forgot the total of how many mah's but i know it consist of many-many battery cells , its size is 9 inches long x 6.5 inches deep x 0.5 inch thick , weight is i don't know - maybe half a pound , after full charge of 4.5 hours it can power up my ibm r60 for minimum 3 hours depending how i use it , input and output as mentioned on my 1st post above , it is connected out by a special pin cable , what i did was i cut it off , inside is just two wires , i went to my local it mall - low yat in KL today , to buy a DC12V to usb to twin car socket extension adapter - cost me usd5.00/- , of course it's made in China - the best price there is in this world ! , it's input voltage is dc 12v to dc 16v , output is max dc 5A , usb output is dc 5V to 5.4V max / 500mA , total output is 60W , i cut the cable ( consist of 2 wires also ) of this socket adapter and join it to my battery pack cable out which i have cut just now , and i use my original dopod / htc car charger socket which input is 10 to 30 vdc and output is 5v , 2A , the end of this cable is a mini usb , then finally connect to my dopod u1000 , and presto ! it works flawlessly charging my u1000 for half hour , i monitored it and it's not hot , from battery pack i touched all the way to the adapter socket to my u1000 , after half hour it is slightly warm because of the lights but not hot at all , i will further test on total how many charges and the hours that i can use on my u1000 until the external battery runs flat for another full charge again . And i will also test on my other phones and devices later too . I can imagine how wonderful that i can bring my u1000 to anywhere without worrying of real powerful battery backup for some real serious and long work on my u1000 , plus i really put my external battery to work on not only my initial ibm r60 laptop but now it's for most of any 5v 1A electronic devices , and i have that feeling of not wasting the full potential of this big external battery pack that i have . Thanks for reading everyone , i wish u best regards and cheers ! jimmunsw

I just got my Athena dock which I paid 2 Euro + 20 Euro postage from : http://stores.ebay.fr/mobilebird-de-Online-Shop
I have tested it and it works fine, the USB port works with both a mouse and thumbdrive.
VGA out works and not tested the S Video or coax video out.
I think the spare battery needs to be fiddled a bit in the charger before it starts charging (there is a light thant indicates status).
It also holds the keyboard in place.
Hint: I waited until the auction was about to expire (10 sec) before placing my bid and got it as no one else was bidding.
Well recommended!
Dear Athena owners ,
I have modified an O2 mini desktop charger to suit my dopod u1000 battery charging usage as an external desktop charger . Here is how - i bought a o2 mini desktop charger ( made in china as usual ) at usd 2.00/- only ! It is only a desktop charger with mini usb connection ( no cable provided ) and you have to use your original power adapter to connect to this charger . It is 5V , 1000mA , 4.2+/- 0.03V , 500mA +/- 50mA marked at the back of the charger . Comes with 6 pin to connect u1000 battery also 6 pin , I just cut off some edges on the left side of the charger as the u1000 battery is slightly bigger , by using a burning candle and a used nt cutter or blade , heats it up and slice little by little , it may looked ugly and uneven at first , but after complete cutting it off and adjusting your u1000 battery to sit properly , then you just use another new very sharp cutter to slice off the rough edges , make nice , then you put in your u1000 battery , you have to use a rubber band to tie it around to secure the battery , connect cable and power adapter and then just charge it as a desktop charger . Thanks for reading and cheers - jimmunsw
Hi there!
My brother just bought me a spare battery. Well it still needs to be charged after usuage. The thing is I have to swap the batteries everytime I used them both. The solution is to buy a cradle to charge it but these are kinda expensive.
My solution would be to build my own charging cradle. But I lack the knowledge of electricity skills to succesfully making such charger without blowing up my battery. Therefor I'm asking the community on XDA for help!
Well this is what I need:
- Battery has 3 connectors: + and - and on in the middle but i dont know what that is.
- I have a usb cable with 4 wires (black/red/green/white)
- I want to connect the usb connecter to my PC or AC adapter and the wires to my battery.
This way I can charge both my HD2 and the spare battery at the same time.
The question is, is this possible and if yes, can this be done just like that or do I need transistors or conductors (or whatever they may called). It needs to be safe, I dont wanna blow up my battery or my AC adapter nor my PC...
Do not even contemplate it.
It is clear that you do not know enough about batteries.
A quick google for desktop chargers came back with one for only £30
For 25quid i got a spare battery, desktop charger and 2 screen protectors from e-bay. Carnt go wrong at that price
I know that the AC adapter converts the input of electrical energy to my phone, I believe my phone does it to my battery too (thats where I'm not too sure).
All I need to know is if I can charge the battery safely when connecting the red wire to the + and the black wire to the - side of the battery... (The green and white wires are data)
I'm not to sure because the AC adapter has a different output than the PC USB output. Although the USB dilivers a tiny bit less voltage it delivers a significant less amount of Whats (or Amps) Basicly that means it just takes longer for the USB to charge as long as the voltage remains identical. (The USB delivers less voltage but the effect on damaging the battery is minimal because the difference is discardable)
My actuall question was: can I connect my battery directly to the AC adapter or do I need to convert the electical energy again (if my phone does a second convert after the AC adapter).
You can find chargers on eBay for less than 5usd. Buy one or you will fry your battery.

Watts not Whats
Simple answer: No you cannot connect your battery directly to the AC adaptor.
Detailed answer:
The USB port of a computer/AC adaptor provides approx 5V and a variety of currents depending on what the USB lead is plugged into.
This 5V goes to the phone.
Inside the phone is the battery charging circuit, this detects the level of charge in the battery, controls the voltage and current going to the battery to stop it releasing too much hydrogen which would cause the battery to swell and explode (look on youtube for lithium polymer battery fires).
If you think you can create a charging circuit (including selecting the right ICs and programming them) without burning yourself in a hydrogen/lithium fire, be my guest.
Incapable of making an external battery charger...
Here I am trying not to be a complete idiot and then I go and spell watts the wrong way...
But tnx for the replies, that was all I needed to hear... I guess I'll be swapping batteries after all untill I find a cheap external battery charger...
Cheers!!!
Amzer makes a very nice cradle with charging slot for your spare battery. I got mine for $28USD. I'm not going to provide the link to the outfit I bought mine from because they weren't the best of suppliers to buy from. But the Amzer cradle works very well. Downside is that you cannot use it if you have a case for your Leo that wraps around it, and is designed to stay on. Leo must be caseless to fit into the cradle. But even if you don't use the cradle as a cradle, it does have the ability to charge your spare battery.
Hey all, I know this is a development area - but there is no General section for the G9... anyway...
I have an 80 Gen 9 original none hard drive none turbo which im installing in my car. So far it looks really really good - ill post a video when i finally get the facia on it. However I am struggling to keep up with the charge power wise.
I originally brought a tomtom microusb charger - which according to form puts out 1 amp (not enough). This works fine on my HTC evo 3d, but cant keep up with the power consumption of the 80. It does not show as a "slow" charger.
I then brought an adapter off ebay that has a 2.1a and a 1a port. These originally showed as slow, so I made an adapter cable shorting the data pins so it knows its a charger - but neither port can keep the thing powered, and both these and the tomtom 1 amp seem to discharge at the same speed while plugged in.
Im waiting on one from newmp3technology that is stated as a fast charger for the archos g9...
Now, on the device i have turned off bluetooth and wifi turned off, backlight always on at around 1/2 brightness, and i have it running an external laptop hard drive off the port on the back. GPS gets turned on when necassary - but doesnt really seem to negatively affect the power situation (which was kinda surpising). Ive set the maximum CPU usage at just 600mhz to try and kerb the power consumption also. While driving i have Poweramp continually playing, and have used copilot on and off for sat nav. It doesnt drop fast - but nor is it staying fully charged. Im sure I had no problems with this while on AC power in the house.
If anyone knows of a working fast charger, or has a suggestion I would be most greatful. I may between now and then test with an invertor and ac power supply. One other idea I have is to run the USB hard drive with a powered USB hub, to move the power consumption away from the device.
I believe there was one of those dual-usb chargers from Belkin, but knowing them the charger could be pretty expensive.
It also has one 2 amp and one 1 amp slot, though I have not tried it yet.
i have this
http://www.newmp3technology.com/francais/all-Archos-model-charger.htm
This is an other option www.newmp3technology.com/francais/archos-101-80-g9-cigar-split.htm
I also need to be able to run/ charge my 80G9 turbo on the road for long periods.
first the basics, the original Archos cable must be used to get max charge (its short and has the log like thing inline near tablet) every other cable/ wall charger I have tried will only give weak charge and if using tablet with other cable it may never charge at all *if you know this great, but everyday others have to find this out the slow or no charge way
now, that applies to the wall plug for sure but with a cigarette lighter usb adapter I'm not so sure you will get enough juice just with that cable. If there is a 12V adapter or complete plug and usb cord that gives full needed output, great. until its used and proven (real world) I don't know if it exist yet.
the best alternative may be to use a Power Inverter like one below, there are so many available I don't know if the ones with usb outlets would work, I have a cheap inverter I need to try but just with factory Archos wall plug & cable (I've used it in the past to power a hand grinder etc. with no problem, car battery stayed charged up even when vehicle was off)
http://www.amazon.com/Wagan-2003-6-...?s=electronics&ie=UTF8&qid=1329710122&sr=1-17
I use the original Wall-Charger that came with the Tablet in conjunction with an HTC USB Cable that came with my HTC Desire.
It's charging as fast as with the original Archos USB Cable.
Even the small Wall-Charger from the Desire charges the Tablet very fast.
OK Ive received the so called fast charger from newmp3technology and it registers as a slow charger using the original supplied cable from archos. It took 17 days to arrive... not particularly happy with newmp3technology.
Anyway, I have found that the tomtom charger does actually charge the system while it is active - even though its only a 1 amp charger and the system requires 1.5 amp. Over about a week of driving for approx 1.5 - 2 hours a day the charge has risen from 0% to 19%. I had a USB extension (no more than 1 meter long) in line with the charger and that actually slowed the rate of charge.
The system is active the whole time - usually playing music through power amp, and sometimes using GPS via copilot. Ill test again to see that it can still maintain charge with GPS running. These devices really only require a small amount of power - I used to run a full computer in car and that pulled a bunch of power.
Here's the general section

Hi, I would like to ask if there is anyone of you happen to be via a docking station charge the phone for a long time ? Yesterday I played Real Racing 3 which understandably draining battery as hell , so I put the phone in the dock station and keep playing RR3 but battery had been keep drained so I turned off the game and tried simply just looking over the net with the phone still embedded in the dock but situation has been the same percentages keep going down . So I turned off the display and let it charge if it stabilizes . I've found that one percent will be charged in 5 minutes which means over eight hours to full charge . I've tried to force kill Smart Connect (I've read that might be solution for this unusual draining) but nothing hapens...even about 2 times that process Smart Connect itself again launched and let notification popped. Otherwise I've tried to kill all applications to sure that no application is taking battery time. My charging set is :
1x Dock M36H
1x USB charger original manufacturer
1 MicroUSB cable length 2m (buying longer because of log distance of the socket)
My observation is that it could cause just that long cable because when I charge the phone with shorter on one side connected to the dock and on the other side to the PC and it worked flawlessly , and the phone has been around for 3h charged . Do you have some experience with it ? Or cable length does not affect the charge? Thank you for your insights
not only the length, the built quality is important too (armoring and connectors). the more tick it will be the better results you'll have (transfer speed and charging efficiency). for the dock I advise a cable of 1 meter only if it's cheap.
Made in ZR
To further test and see if your extension cable is faulty:
connect the extension cable directly to the phone itself, not the dock and see how fast it charges compare to the stock. You can also download the app called better battery status as it shows the actual charging current. by comparing using just stock cable vs added extension, it should give you a better idea.
