[Q] Does this external battery work for the Xoom?

http://www.amazon.com/Portable-Universal-External-Battery-5500mAh/dp/B004T8EW08
I hope to get an accurate answer because I'm about to order it
Thanks!
Q80
P.S:
Good news: I found the one that would work as an external battery for the Xoom.
It has a 12v/1.5A output and looks to have the same tip of our xoom charger!

To be honest I don't see a small enough pin there.
Sent from my Nexus S using XDA App

Motorola isn't even listed. Etc. Doesn't always mean it'll be included.

You DO see it puts out 16-19 volts, right?
IOW, don't buy it.

I have yet to find an extended battery that works with the Xoom, either the pin connector is too big or the output voltage is too low, I have bought these and they dont work either so I doubt the one you listed will

The weird thing is that I saw the same device on other website which has a pin in the old nokia chargers size .. the pin may be not included but you may need to buy it separately!

FYI, the device is listed on different websites and sometimes they mention Motorola and sometime they not .. it's not our issue since this is considered as a universal external battery.

The thing is .. if it could charge the hucking laptops and even cellphones then why it wouldn't work for our xoom?
I mean isn't there a way to convert the 16v into 12v ??

The ones you've listed are usb based output which barely gives 5v and we indeed need 12v.. but the one that I asked about could provide 16 to 19 volts and that's the difference.
I hope we find an external battery for our Xooms .. cuz I'm working on a project for the xoom that needs an external battery (hint: hand made keyboard docking such as the transformer )

Not efficiently at the 18W that's needed to fully replicate the charger. Plus that, I suspect the charging plug sets the output voltage (kind of like what the Kensington chargers do).

Wireless Charging on i9195

Hi there,
is there a possibility to charge the S4 mini via a wireless induction-kit like the S4 has one?
My research did not find any related products to the mini, just for his big brother
If so, could you tell me where I can get one in Europe?
Thanks in advance

+1 I'm also interested in it very much ^^

sorry not lauched...yet, we have to wait abit longer

I don't think we'll see this on the mini as there are no connection points like on the S4 and S3. Unless they are hidden under the inner cover somewhere.

Here http://mobileandphone.com/samsung-galaxy-s4-mini-vs-galaxy-s4-comparison/ is writed that both phones have integrated QI chargers:
The S4 and S4 mini have a removable battery and microSD card slot and native Qi wireless charging without the need for a dedicated cover.

Is this fake?
And maybe this http://www.aliexpress.com/item/HOT-...r-Galaxy-S3-III-i9300-Mini-Qi/1026431226.html QI charging receiver from Galaxy S3 Mini will be compartible with GT-I9190, I9192, I9195?

The dimensions for the S3 mini and s4 mini are different though

I received one of these last week and it works great. It seems to charge pretty quick but galaxy charge current monitor says its only charging at 260ma. It seems a lot quicker than the S3 charging with the palm wireless charger which showed 500ma on GCC.
The base unit is also a lot less fussy over positioning than the palm was and it works ok through the igard case.
One downside is the nfc only just works now,and is very fussy over positioning and is slow to react.

The back cover fits fine you can't tell the qi is fitted. It's much thinner than the palm one I had in my S3 which gave bumps on the back cover.

No the SD card slot is behind the battery so isn't affected by the coil.

It plugs into the usb slot but that in itself can be a pain. If you find yourself needing to use a normal usb charger you must first remove any case, then remove the back cover and then remove the charging coil and then reassemble it.
I might look into hooking into the other side of the usb socket when I get time, though I suspect it will probably involve disassembly and soldering something permanently in place.

[How To] Moto G Wireless Charging Internal Mod by jamlvs

--update--
If you are not rooted you will need to have the screen locked, in the beginning I was using the pattern lock. Right now I have a custom ROM (CM11) with root and have installed the "Moto Floating Charge" (needs root). That way I don't need the pattern lock. You can find more information about the Moto Floating Charge here.
----------
Based on this xda topic, I decided to do the same.Unfortunately, that thing hanging out of the phone and the cancellation of the micro usb port was not a good option for me. So I decided to try to put the adapter inside the phone.
The adapter:

First we need to remove the 14 torx screws on the back of the phone.
If you need some help, just see this disassemble video until minute 2:20, including the part of disconnecting the battery!
https://www.youtube.com/watch?v=Fd3AZSXhOf8
First I looked in to the micro usb adapter to see what contact's was using, in this case (I don't know if they are all the same) it was the 2 in the edges.
I opened the adapter (It's just some sticky paper) and found out the main 2 spot's (+5v and ground) and a third spot that says 5v +1. Have not used it but it's there.
Green - 5v +1 (not used)
Blue - Ground
Red - 5V
I then connected the adapter to the phone and made a continuity test with the*multimeter and found the 5v spot and a lot of ground spots has normal.
The installation:
First I removed the connector and installed 2 wires.
Then put it in the right place using a double sided sticker (included).
Then solder the 5V:
Then the ground and it's all done:
Now just install the back cover, and put the screws back on. You wont*even notice it's there.
If you need some help, just ask.
Here it is in action:

Thanks! I'll try it in one week. I opened my Moto G already it is very easy.
We can charge normally than with cabel too? Or will it destroy something?
And change files via usb-cabel on PC will work too?

That will do. The "problem" with that model is being all in plastic so it is slippery. Mine is the "Qi K8" model and the center is a kind of "rubbered" material. Just confirm the output, mine is 5V 700 - 1000 mA.

Sweet!
That's awesome! Good work! I just might have to do this. Anyway, I have a question. Do you think it would cause a problem if you had the USB cable plugged in AND it sitting on the charger? Not that I'm ever going to do that, but just curious.

Good work finding alternative soldering points. The micro usb connectors are so tiny
Time to get the screwdriver out

Just like i did in the other thread, that's a great mod you've done mate.

Connecting the USB cable will work has it should and the wireless charging will not interfere in the data transfer or the charging (since is already charging).

Wow this is slick, never really soldered small electronics before though, not sure if I want to go there.

you need a QI Wireless charger. It's a pad which you put your phone onto and will send "waves" to the receiver you've just plugged/soldered.

It looks like mine but mine is 600mA, that must charge faster with a 1000mA charger. It's a QI just like mine, go for it. :good:

Thank you so much for the video of it being plugged in while wireless charging! I'll probably do this at some point. Good work!

This is a really great job. Well done

Do we have to set lockscreen patern for this mod?

[Q] my m9 is not charging when i connect it to my PC using the cable

The HTC m9 charger does require a fair bit of whack and whilst a USB port should give it something, its really not enough juice to power it up as it should be.. No one will be able to charge up as they would if it was connected to its own charger..USB 3 should be a bit better but still not sufficient..
This is normal.

The HTC m9 comes with a 1.5AMP charger, USB can deliver 500mah which is a third of the strength, now although it should give it some juice it's never going to be anywhere near as good, I would say try another laptop / PC, try different USB ports, USB 3 can deliver up to 900ma so you should see some results there.

?? no mate, I mean that USB sockets can deliver a higher amperage so it should charge faster than USB 1 / 2.

Ah I see, so in that case then it probably won't work. Shame really. I'd be interested to see how much power its actually delivering via a normal cable. Not sure if there's an app for that or not

Charging cable

Heyo!
A few weeks ago I sent my LG G4 into the service because of faulty connector ( known issue that makes device to stay on bootloading screen ) and then for a faulty camera. After it has been returned, I saw a BIG, HUGE and SIGNIFICANT problem: charging with the original USB Data Cable ( which came with the phone ) takes more than 3 hours to get to full battery. The time was never great, but it was never like this. I also have a small USB Charging Only cable ( which came with a portable battery that I bought ) which charges the phone in about 1h 30-40m ( or something like that ) from 5% to 100%. The thing is that the small one has been damaged ( almost like the iphone chargers do, but on the other end ) and I need a new one. So can anyone suggest some cheap USB Charging Only cables?

I use the cable from my Galaxy S4 and that works fantastic!

If it's cheap then it's unbranded. If it's unbranded how can one refer to it?
You want links to cables from eshops?
The world is full of USB cables. Just try cables from your older phones, or if you don't have, from phones of friends or family.
In the end, just buy one. They' re... cheap!

Cheap sould mean cheap in most parts of the world, right? I would have said 'thanks' for a damn link that led me to some usb charge only cable for my phone. If i had any other cable that would work, from me or anyone i know, would i still be here asking for that only so i can get a frustrated answer from you? Thanks for you devine help and advice because i can now die in peace. Please close this thread. Case solved.

Me too, it used to charge fast, now it's so slow, I change the cable, it's way better... but cheap cable they gave.

Hello,
Same problem here, yesterday my usb cable shows me 4 hours to charge while he usually tells me an hour even changing decision so I took another usb cable (the one in my X98 tablet Air III) and worries disappeared. I do not know why and how, but good .. LG really starting to disappoint me (bootloader block, problems with Rom, load, heating, autonomy ..) ..
