Jasjar Battery Extender-not working :`(
I purchased the Jasjar battery extender (the one in the link above). And it turned out not working. Instead of charging, it helps drop the Jasjar battery more rapidly. :`( What could be worse than that. See my email threat with the vendor below.
My PDA is imate Jasjar, the one this product is designed for. The name of the product and the image posted in the web store is an imate Jasjar. So, it has to work fine.
I did measure the voltage output of the battery extender and it shows 5.1 - 5.2V which is the good range for charging the imate Jasjar.
I really cannot accept the fact/excuse that there is possibilty my imate Jasjar is not compatible, like you said.
I have tested both battery extenders I have, so they are the same characterics. I do not think even though you send me a new one, it will work out too.
I can only test out the compatibility with imate Jam when I give the second one to my brother. If it does not work out, I can accept that, as it might not tested before with imate Jam, and the product is not listed compatible, at least, even though you have confirmed to me that they should be compatible. But with my PDA, imate Jasjar, I really cannot accept that fact, that instead of charging the device, it consumes the power as well.
Please help report this back to your engineering department, so they can test it more thoroughly and fix the charging/regulator circuit.

Because of my curiousity, I finally opened up the battery extender. I wanted to find out what is causing it instead of charging my PDA, its eating up the power of the PDA.
I was so surprise, inside the black box, there IS NOT circuit whatsoever!
The only two electronic components are a LED and a resistor that is connected in series with the LED, this resistor limits the voltage to the LED.
The 4 AA batteries are in series, and the output are connected directly to the USB cable, means actually the PDA is charged directly by this 4 AA WITHOUT any protection circuit whatsoever.
This is really really really really bad!
And I can say, this is really dangerous, as if the actual alkaline battery works at 1.5V fully, 4 x 1.5 means it will supply 6V to the Jasjar directly. Jasjar is only accepting 5V DC for charging it. Jasjar is a very expensive device, over $1,000.00, and yet sensitive.
I cannot believe they dare to do that. I mean, look at the products below posted in the web store, it says very clear, there is a special circuit, design to protect the PDA from overcharging and short circuit. And this is definately a big lie.
I definately cannot use this products and will not test any longer before I damage anything.
FEATURES:
· Requires 4 AA batteries, which will charge the PDA roughly 2.5 times from a complete discharge.
· Charge and use your PDA at the same time.
· Special circuitry design protects your PDA from overcharging and short-circuiting
· Charges to 45% in 20 minutes
· LED indicator light
I've got one of these and it charges my MDA Pro fine, i'm supprised there isn't any voltage regulating circit in the device though.
Re: Will the JAM 4xAA battery extender work on the Universal
UPDATE: Tried it - no joy.
But based on what some others have said her, maybe that's a good thing that my JAM still works!
I'll stick it on ebay, along with a few other jam things....

A mate of mine bought one for his Jam. It didn't work but a quick investigation revealed that you need to short 2 of the "usb connector pins" in the plug. Windows PPCs and smartphones seem to need a voltage on more than one pin in the mini usb plug. I read somewhere that this is why the device won't charge unless you have Activesync installed - I presume AS sends a signal down this other pin.
We used the charger on a JAM and a SPV C500 with no problems. You don't get as much extra battery life as you would expect from the rating of the AAs. The voltage from the AAs drops off quite quickly.
which 2 pins
which two usb pins?

An easy fix i found is use an htc headphone adapter between the charger and the phone. I have used the 4aa charger for years and love it, it triples my run time with 2700mah rechargeables.

Anyone heard of this product called "Swiss Charger GPower 1500 mAh Rechargeable Battery" for Samsung Galaxy S II? Any reviews about it?
it looks very nice but cant find any reviews on it, would be keen to see the quality of it
I have been using this product. It is good...it charges your battery to almost 60% from complete 0..very useful while travelling...
Plus with its box it accompanies a PC-Phone cable and 1 scratch guard.
Swiss Charger GPower
Hi
I have been using the Swiss Charger GPower for more than 3 months now,
Pros
- Does the job of adding extra battery backup
- adds 40% more battery backup
- give the phone a bit of protection
Cons
- the sleekness of S2 is lost
- makes the phone heavy a bit but extra battery time is worth it
Issues I am facing
- I have a S2, GT9100G, 2.3.6 stock none rooted device, i used to find that the USB connectivity with my widows 7 64 bit was not stable,
- just after 5 min the device would not work and the driver will show "device not responding"
- removing the USB cable, and reconnecting brings back the connection
- to hold the connection, I had to keep my finger moving on the Phone screen looked as if when phone goes to sleep, the USB conenction was not waking up
I contacted the Samsung service - and as a solution the reflashed my handset, things worked fine and my phone was connecting normally with no failure
but
when i put it back in the Swiss charger and try to connect, i have the same issue - so the original issue was not with the device but with the charger
has anyone faced a similar problem? what is a possible solution?
Will appreciate a reply as changing between covers might take its toll on the phone
Cheers
hie i bought this swiss charger yesterday in india..
it started well showed 2 dots of charge level...
i utilised it to charge my sgs2..
bt aft dat it didnt showed anything..
its not showing battery level even aft keepin on charge whole night with my cell..
pls suggest me how to charge o replace this product...
Dear Dholyabhai,
When you press the power button of GPower, it shows the blue indicator that it is charging, the amount of charge at hand is indicated by the number of blue indicators. but after some time the indicator does not show up (I guess this is to save power wastage). you can still see the phone being charged in the Phone charge indicator on the notification bar.
when put the phone with Gpower to charge, it looks both get charged and since the battery now is 1500+1650 the time taken goes up a bit (depends on the charger trickle rate)
Cheers
can someone post pics of this

Today bought this device in Spain (25 euro), was looking for it before in Ukraine, but only available by preorder.
Nice looking while SG2 inside, soft touch quite durable as for me.
Everything else you may find on above youtube video. Definitely Gpower "must have" device for long range traveler as me.
that swiss charger does look ok , have you ever thought about one of these
http://www.amazon.co.uk/TeckNet®-Du...1?s=electronics&ie=UTF8&qid=1335310567&sr=1-1
or even a desktop charger and spae battery??
that usb battery pack i linked should be good to charge your sgs2 over 3x from empty on stock battery
That one also good which i use now (see screenshots). The big advantage here that you can insert any capacity NiMh accumulators and also ordinary unrechargable batteries. Moreover if accumulators inserted they are charging slowly via sunlight panel + you got long lasting flashligt packed with 5 diods. Tested one time on 2500 mah NiMh accum. constant lighting time more than 24 hours.
So now I got extended battery 2000 mah + swiss charger 1500 mah + extra accum set 2500 mah = 6000 mah total power.
I bought this device 3 years ago in my city and still it selling here. Price is around 35$. It comes with commonly used adapters for Nokia, Ericsson, etc phones + microUSB+miniUSB.
I'm looking for an external battery charger since I bought a couple extra batteries for my phone.
anyone have experience with a certain charger? Obviously I don't want something that will damage my battery but nothing that will break the bank either.
Thanks.
Sent from my Incredible 2 running Zeus 1.3
Anything wrong with the charger that came with the phone??
I need a charger that I can put a battery on so that I can use my phone out of the house and a second battery can be charging at home..

Yeah, sorry I probably should have been more specific but I dont know the exact name for them. haha
It's like the dock "travel" charger for just the battery, not the battery connected to the phone.
I havent been able to find something decent (crappy charging, made in china).
Ok a little update for those interested.
I ended up buying some cheap (REALLY cheap) charger off ebay not expecting too much but just experimenting.
The charger itself looks something like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The 2 metal prongs connect to + and -; the charger is able to read which is the + and which is the - no matter how you set the battery in there. The bottom part that pushes the battery toward the prong is extendable or you can flip it 180 if you have a really small battery.
-Flashing red and blue light means charging
-Dull red light while plugged in means fully charged
-Dull red light while not plugged in but with battery set up means the pins are set up correctly on the terminals
NOTE: do not take batter off/put battery on while the charger is plugged in. It can ruin the battery.
The exact one i bought:
http://www.ebay.com/itm/270908124203?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
(no problems with the seller, they actually sent me a few free ones due to a misunderstanding)
Now for the review and my experience.
Pros:
-Fits any battery, interchangeability of pins (differentiating + and -) means you can fit any battery really
-Has a side USB port so you can charge a battery and plug in your USB cord to the phone and charge it at the same time
-Voltage input is 110-220V so (with an adapter) you can theoretically (will test this summer) plug this charge straight into an european plug or north american plug.
-No problems so far with over charging; Charger stops charging the battery when it is full
-Has a light to tell you when the battery is done charging and when you have the pins connected correctly to the battery
-Compact; Small and plug folds up into unit.
-Charges a fully dead battery quickly.
Cons:
-No instructions when I first received this product (i know what you're thinking, how hard could it be to just charge a battery but I was reluctant to rely on the self detecting terminal feature)
-While charging, the light on the unit (the one i posted/bough) flashes red and blue like cop lights and is very bright so it might be a problem if you are plugging it in overnight in a bedroom. Also this is a normal function of the charger but i thought it was malfunctioning so they sent a new unit but then figured out its normal.
-Looks cheap
-Dont know how long it will last for (really cheap so buying another one isnt a problem)
-Noticed that after i pull a battery off the charger and use it the phone states it is at 99% (undercharged) although if i try to bump charge a fully charged battery it wont charge more. This could be a problem with my battery/phone/etc.
-Nothing else really
So final verdict on this product:
Its a great, affordable charger; works great if you are traveling and need to charge an extra battery. Will fit the Incredible 2 extended batteries and technically virtually any battery. Its pretty easy to use once you know what the color lights mean and how to set a battery up.
If anyone has any questions or want more pictures of this product just reply in this thread. Hope this helped out anyone looking for a product like this.
i just wanted to jump on here and say rthank you for posting this. i just oredered one for myself. i droid incredible 2 usb port took a dump on me and now have no way to charge it now without taking it apart and replacing it. thanks again for this info. it will hold me over till i am ready to fix the usb port or get my upgrade. i will just the ftp app from the play store to transfer my files till then.
so just an update. just recieved this device today in the mail. only cost less than four dollars and is working perfectly. thanks again for this post.

mine did the same thing just a few days ago only issue I"ve ever had with the phone...I actually ordered this same one off of amazon about 10 mins before I saw this, lol. Glad it works well
I just got a portable battery box (2800mAh) for $14 from monoprice. (LINK)
Nicely built, relatively small, and about to test whether it will give me 1.5 full charges as mAh would suggest (2800mAh / 1800mAh on HOX = around 1.5 charges).
Box itself doesn't come with any charger, but is able to be charged by any charger with Micro or Mini USB connector (yep, it has 2 inputs).
Output is a male MicroUSB connector that fits HOX nicely (duh!).
Output: DC5.0V 800mAh

}
I'd imagine if you want to use the phone while charging from it, you can connect them with a female-male MicroUSB connector.
The charger has a button that shows the charge level of the box with 25% increments (4 lights).
Has another light for "FULL".
As soon as I connected the box to HOX, phone immediately showed that it's being charged, as if from the regular charger. Not sure what the current is, but it may come across as slow charge (USB port charge) as opposed to AC charger.
So far I tested the charge over 10 minute deep sleep period, and I got this:
With the box, in average HOX charged for 2% every 10 minutes.
That would suggest that it would take this box 8.3 hours to charge HOX fully, which isn't bad at all, considering you're free to use it while it's charging.
Over next day or so I'll try to completely discharge the HOX and charge it overnight from the box. I'll see just how much this box can spit out.
---------------------------------
EDIT/REPORT:
I discharged my phone to 5% yesterday, disabled wifi and BT, and connected it to batt pack to charge overnight.
It turns out that this batt back is crap.
Overnight, when phone was in deep sleep with wifi/BT off, a full battle pack charged my HOX only by 55% (I charged the batt pack before using it). Even considering some small drainage during charge, I'd say this pack actually acts if it had just over 1000mAh or so, nothing close to 2800.
Oh well, gonna return it and keep looking.
shouldn't this be in the accessories forum?

That's a good option too, although I actually like that monoprice's sticks right into the phone, so you don't have to carry a cable with u.
Also, it seems smaller and cheaper.

I know of certain defense organisations that allow the fixed connectors but not those with detachable cables. Disallowing the cables reduces the risk of the cables being used for data transfer.

huh?
It's a security standpoint from Defence services (IE: Australian Army, etc) who wish to minimise security leaks. A data cable can be used to link up other devices, not just the charger.

Okay, and I guess if I were flying in outer space, my suit was venting air, and the only thing that would save me is connecting a batt pack to a phone - in that situation a cable could freeze solid to a connector on the batt pack, making batt pack unusable, and thus killing me.
WRONG!
That's when Iron Man comes flying to the rescue thus saving your life and getting an autograph that you could sell on eBay for some money and covering your costs of the HTC One X.
OK well, turns out that this batt back is crap.

Brother I got a similar equipment and is not as great as you pretend to be.
Sure the price is cool, you find it with 5 dollars on wholsales but I bet it doesn't have 12 Ah, if it has 10 Ah is good!
Second: the lights are not indicating the right amount of energy recharged.
I discharged completely, and started to charge with an 700mAh charger and the blue lights went on in a 2-3 hours interval and this is not possible.
Also is not possible as you say to recharge 12 Ah battery with 1Ah recommended, in just 3 hours as you mention.
This device needs like 10-12 hours with 1000mAh to make it full, and as I said the light indicators are not precise.
When I first got it, It had some power in it for test I supose, but it was showing all 4 leds lighten up. I powered my 33% Samsung Tab 2 7inch and started to charge till it reached 77% and then died!
I put it to recharge! In few complete cycles the life time will improve, but I don't think is able to recharge a 4Ah tablet 2 times! If is getting one time is perfect! Not with the tablet open, at least!
Another thing people should know is they should use their original cables, the connectors don't fit on my tab, and on an old Sony Ericsson phone. Both of them are the wrong size!
The design is nice, the price is good, but I don't think is a good battery pack!
Another thing people should know about it, is not multitasking. If you plug in a Phone and a Tablet in the same time, is dying fast, so.. you must choose!
I recommend this product for his low price! Is not so big either, but the cables and adaptors are junk.
Good luck guys!
Usually these batteries are of poor quality

Everything's from China

But everything's made in China?! (j/k, I know what you mean.) Most of the stuff sold on the ecommerce b2c sites are of the Shanzhai variety).
But isn't that always the case, you get what you pay for.
When I bought my Note 8, they offered me a deal to buy the Samsung 9000mAh power bank for about 600HKD, which is about 85USD. Expensive yes when compared to the typical cheap China stuff, but then again, I don't relish the thought of battery acid exploding on my leg. Though some might. I guess.

Hey there,
greetings from germany. Pretty sure this belongs to "Questions and Answers", if not - please hit me and move it.
I am confronted with a, in my opinion, strange problem regarding my P-601 Samsung Note 10.10 2014 Edition.
I will try to provide every action I took and what I figured out so far that noone that wants to help will need his crystal ball. But the first actions are about a year ago, so forgive me if I cant remember exactly.
Device: Samsung Tablet Note 10.1 2014 Edition (P-601)
Problem: Charging slow AF but lives, can be turned on, can be loaded via USB. (But more power is drained while using than can be delivered by charging = dies sooner or later while beeing used)
OS: LineAge OS
First I thought, EASY - get a new battery, done. Wrong.
I ordered a new battery, a (2) "vhbw" battery for "T8220E" - same mentioned on the original Samsung battery.
This is a year ago, In my belief I did get the tablet to run, and charge- but had the same problems regarding the charging speed. Slow AF - but I am not sure! Life happend, things came inbetween so I did put everything aside. Now I want to use it in my home gym, so thats why I came up here.
My next suggestion was that the charge electronic maybe the problem, so I ordered a new one, built it in. Didnt change anything. The (1) Original battery, is still charging slow af.
The new battery, doesnt do anything! If the (2) "vhbw" battery is built in, I am not able to turn the tablet on OR charge it. Its just a brick with this battery.
So what did I do? I ordered a new battery, from a well known german company trading parts like this, a (3) "original samsung battery". Guess what, the tablet does nothing.
So i thought, maybe your new charging electronic is the problem. So I put the (1) Original Tablet battery in again, and well - it runs, can be turned on and can be charged (slow af).
So the charging electronic is fine. Display is also fine.
I did confirm this several times by changing the batterys in and out, the new batterys (2) and (3) are "dead", the (1) original battery runs.
Right now I am stuck. It seems that my Tablet is blocking any battery besides his original one.
Note: I cant access Recovery Mode with battery (2) and (3). Its really dead. They where also charged atleast an half an hour, just in case they were delivered "really dead at 0%", which would be new to me because most devices or batterys come with atleast 25% battery status.
Note2: Yes I did use a ****load of power adapter and cables all in combination, same result.
Any help is really appreciated! Thanks in advance.

Hello, I came here looking for recommendations for a new battery for my SM-P600. Could you tell me where you ordered your OEM one from?
As far as your problem, do you have a multi-meter? There are very cheap basic ones if you don't. Anyway, you can test the seemingly dead batteries with it to determine if they are in fact dead, or something else is going on.
Secondly, do you happen to have a hobby charger? With these, you can charge pretty much any battery L-ion or other. You can also do a drain test with most of these to determine the capacity of a battery. That is all I can really think of thus far. Determine if the batteries are dead. Oh one more thing you could do with the multi-meter is test the current being applied to the battery. I believe there are some free apps in the Google Play Store that can also tell you the electrical current going into the battery. Perhaps by doing this you can determine if the problem is something in the tablet itself. If I think of anything else, I will let you know.
Thanks
Hey,
thanks for the feedback.
You mean battery (3)? I ordered battery (3) from ng-mobile.de
Funny that you say that with the "dead battery", because I just had the same thought 10 Minutes ago. Those batterys were manufactured years ago I guess and were just sitting cozy in their boxes, I guess they are deep discharged. (hope this vocab is correct).
I have pretty much everything that is measured "useless" in a normal household, but sadly no multi-meter (no more). If those batterys are deeply discharged, it should be possible to be reanimated with very low charging power. The lowest I should have is a USB 2.0 Port on my pc (which were it is connected right now) or a oldschool dumb power bank without any intelligence).
I will keep this updated.
solved
It worked. About an hour connected to a USB 2.0 port of my computer, and it just popped back into live. Thanks for sharing your thoughts with me!
There have been reports of the plugs of replacement batteries for these tablets not fitting properly.
Also bad solder joints at the battery connector.
And a certain behaviour i oberved myself, requiring certain custom roms or chargers in case of my P605:
In soft-off state tablet will charge at 0,5A instead of 2A max
and
When powered on it will charge at full power until the screen switches off and it enters standby. Then no charge at all.
