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.

[SOLVED] Good external battery charger?

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.

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_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
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.

Monoprice 2800mAh portable battery box

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?

Hate the ones that plug right into the phone like that. Pretty much makes the phone a huge pain to use. I would rather spend the extra money and pick something like this up

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.

External Power Backup 3000-3200mAh

Hi everyone.
Be care full all things of this kind of battery is just publicity nothing real.
Here is how it's look

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

Inside is just a regulator for charg internal battery and a power up convertor to get 5V
The main battery who run this external battery is just a big flat 2800 mAh 3,7V battery more exact his code is YY 426390P 3.7V 2800mAh 12YE005.
Price tell you how much is plastics, how much is true and how much is publicity.
Here is the pics with image from what is inside.
Power Board covertor up/down from 5 to 4.2V max (that much can take Li Ion battery) when charge extender battery and up convertor from 3.7-4.2 to 5v to power your phone.
All parst who make the extender
The back cover of extender
The EXTENDER BATTERY 2800mAh not 3200mAh and never will get 2800mAh as he convert his power to 5V wher will lose some power on convertor (the button for on/off get hot when is used to power your phone)
Make a litle ajustment for hole of back camera and flash because when you shut in low light and have flash on or auto the white around flash will get back on your camera and picture will get unclear and with to much shadow. I will got a permanent marker black and make the hole black around camera and flash. In this way i can take a pic w/o get some noise from white.
Here is things who get broken easy w/o meaning i wish to do that i never know when i did that but i did it
As advice if you want a battery extender dont get this kind better buy an another 2500mAh and you get more power than from this.
Or use and inside replacement battery than external power battery except the price is very cheap.
Remember this batterys have some power to lose when get charge your phone because is a convertor who get hot (more or less ) but that means he lose that power.
Using my old 3.7V 3000mAh battery from Galaxy I9000 give me more power than this Extender and was only 10$ instead of 19$ who was this.
For around 10$ will worth and not you buy it for extend your time to play with phone but dont expect to much.
Hope some will get this value at least i will feel good because not all got cheat by numbers

Bought one of this (black) on ebay for £14.99, and I can tell you that it can not charge the phone battery over 85%. Phone gets excessively hot whilst getting charge. Also, IT TAKES FOREVER TO CHARGE UP THIS THING. Standard battery charges up in about 2.5 hours but it takes more than 8hours to this power pack.
NOT RECOMMENDED.

Sigh, and I wanted to get one for my Note. I guess it has some issues with build quality. :crying:
Anyways, thanks for the heads up.

I nearly want to bug exactly this type of power bank. Now, change my mind tp buy cheap extended 5000mah instead.

Get 2 this even they dont have real 5000mAh will get more than 1 as 2600-3000 and is a pair of 2 so you will have 3 battery for a very low price and 2 of them it will keep you all day long using alot.
Here is the link of what i order.

Thanks for your recommend link. So, cheap 5000 isnt really 5000. It will be less than that. So i need to prepare 2x 5000mah for me to last a day long. I can order from ebay. Maybe will search other thread to buy it.

Hoping for a reply on this old topic..
Sorry for bringing back an old post, but I have a question about this. I actually bought one of these long before I ever read this post, and to be honest up until it completely stopped being able to charge my internal battery, I never had one problem with this case, and actually really liked it. All that came to a sad halt when one day, it just stopped being recognized by my Galaxy Note when plugged into it. Which mind you really made no sense to me because if I plugged the little Mirco USB tail to another device that could be charged by the same battery and had a Micro USB female to accept it, it was picked up and had no problems charging it, as well, my Note could be charged by any other Micro USB charger, so why all of a sudden it stopped being able to be charged by this case/battery is beyond me since both work fine unless plugged together. I contacted the place where I purchased it and they did send me out another one free of charge and told me to keep the one that wasn't working anymore.
When I found this post, I decided to open the the broken one, and googled the number on the battery "426390P" which was the only reason I found this post. This post actually surprised me because up until this one stopped working, it was working perfectly fine on my SGH-i717. I mean it charged the battery everytime to 100%, sometimes it would charge my battery about 1.5 times before I would have to recharge it. I thought it was the best case I have ever used quite honestly.
So now the real reason for replying to this post. Do you guys think that if I could find a 3.7V, higher mAh battery (or even make my own) that would fit in the case, it would work with the upconverter board that is already inside? I am no electronics expert, so I don't know the functions of all the pieces on the board, but I figured if I could find or make a new higher mAh battery that would fit inside, not only would it beef up the longevity of my battery life on my device, but it would allow me to keep using a case that I actually like and love the way it fits with my device and since I have the black case, I do not have the glare issue with the camera nor any shadowing issues.
I am curious as to what you guys think..
Thanks in advance!

SM-T800 Battery problem

EDIT: Please move this to Q&A and help section.. sorry.
Hello fellow tablet users.
Since the lost 2 weeks my tablet has been acting weird. It jumps alot on the battery levels, one second having 50% then 13% then suddenly 3% then plugging in the charger it has 50%.
I've tried to charge it fully then making a battery calibration but with no luck.. what should I do next? Full reset?
Kind regards,
Ratty

If you have the 8.4" it`s most likely an bad battery connection, due to an bad power connector or the part of the connector that is soldered to the motherboard coming loose, it`s an common problem with the 8.4" with people bending it while in back pockets ect, less of an problem with the 10.5" as you would need an hell of a back pocket.
Samsung knows about this problem, and according to one 8.4" owner replaced the battery connector with an more heavy duty version, some people say to solder the battery wires directly to the motherboard.
It`s quite easy to open the Tab S, lots of video`s on youtube and you just need an plastic pry tool they call an spluger or an guitar pick, I got an spluger on ebay for £1 an replacement battery is £9 an full kit is around $60 for battery and tools if you can do the job yourself.

Reset won't solve a hardware problem, it's very common in Samsung tablets : cracked or loose battery connector : male and female.
This is a close look of female connector:

If it's not fully contact with male connector's pins, you will have battery fluctuation in capacity. The fix is simple: push the opening closer for all six cables.
This is the male connector , it's re soldered to fix battery quick discharge or capacity fluctuation

I'm having this problem for a long time on my TabS 10.5". I think it's time to discard this device but I'm low of budget to buy a good tablet now, is it secure to open it and bypass battery using direct connection to charging cable from the original USB cable? There are some videos on how to do it, but none of this device.

They are not engineered the same as laptops. They always run off the battery, whether the tablet is plugged in or not. This is a series arrangement. A laptop has power source switcher inside and can run off either; that's a parallel arrangement.
The battery completes the circuit. The charge cord doesn't connect directly to the tablet because the battery is in between. Outlet-->charge cord-->battery-->tablet. You can't just jump over a step.The battery completes the circuit. The charge cord doesn't connect directly to the tablet because the battery is in between. Outlet-->charge cord-->battery-->tablet. You can't just jump over a step.
They are designed on an idea that the user will use it on the go, rather than sitting at a fixed location connected to a charger.
As such, the internal circuitry of a tablet allows the device to work only when the battery is connected to it.

Bypass the battery for direct connection
Hi,
I have a similar connector for the battery on a Samsung Tab GT-P5200.
I want to directly connect the (two) wires from USB power source and bypass the defective battery and the normal mimi USB connector.
Therefore can someone help me out with matching the colours?
Tere is just +-(red/black wires on USB) and the connector from the battery has two red, two bue and two black.
I presume at least two should charge the battery and other two should transport the charge from the battery. And the blue ones maybe for control?
Please give me your though, or maybe suggest other place on the bord co connect directly.
Thank you!
