USB charger

Is there a charger that can plug into a USB port. I have universal laptop battery that has two USB charging Ports that I use to charge my phone and would like to use to charge my Iconia. Is there one out there?

Can you splice a USB cable and a charger together?

It doesn't matter what you slice together as it will not take a charge via the usb port. So unless you got some magic spells and chants and perhaps some pixie dust. Then it isn't going to happen.

The reason why it's no is:
Any devices USB port only puts out 5 volts.
The A500 charging port requires 12 volts.
The A500 USB port doesn't charge the battery.

[Q] car install no ac charging with otg

hello guys well i have a nexus 7 that i set up in my car everything working perfect but i cant get the battery to "ac charge" im using this cable
http://www.ebay.com/itm/Usb-type-A-...G-Micro-USB-female-power-supply-/310680595889
the issue is not in the charger because the charger im using when connect to the tablet directly does achieve ac charging but when i plug in the above splitter it looses it, if the cable is meant to separate data from power than why is this happening? how can i get "ac power" or fast charging, I currently have everything connect to a toggle switch that i leave on over night, and i really is not a big deal but i noticed the other day with the navigation on watching videos that the battery is still draining.. using timur kernel
thanks in advance

its obviously the splitter, from the looks of the cable on the micro usb socket its to thin to take the power?

You need to state more info. What kernel? Rom? Only a specialized kernel will allow otg host mode charging.

If you are completely stock, the tablet will not charge while it is in Host Mode with the OTG cable attached. It can be done with a special kernel, though.

Yup, thats what I said.

I can almost guarantee it is your otg cable,get a samsung compatible otg with power cable.

I have a car install running Timurs usbrom (which I recommend over just his kernel) and its the one Im using without issue.

It is because the otg cable does not have the data cables in the powered end that is split off. They need to be shorted to get full AC charging but it is impossible with an Otg cable as it would not work for any data.

So what you are saying if im understanding correctly is to achieve true ac charging you have to utilize all 4 cables in the usb passage?

You need to short both the data pins together for AC charging. But if you do that, OTG is gone.

You are just using the kernel,usbrom is his full cm10.1 based custom rom. The proper otg cables need to have pins 4 and 5 (ground) together on the tablet micro usb end to activate the ofg and power,that why you need the special cable.Your cable only power the device on the usb end not the tablet,it says no device charging in the description.
Also with Timurs kernel or rom the data wire cross isnt needed,or the otg devices wouldnt work.

Simultaneous charging with Pogo and Micro USB?

Can I plug in the Pogo charger and the Micro USB at the same time, and have a faster charge? I've tried it but I don't really know what to compare it to since I'm new to the Nexus and don't know really how long a full charge takes lol
It would be super sick if somehow this could slice the charge time in half.

No. The charging icon will display but the N10 is not charging. That feature would need to be included in a ROM but neither stock nor any custom ROM has the capability. This limitation extends to using an OTG cable and pogo plug.

Thanks man. But I have a portable micro USB charger, if I connected that via an OTG cable, and pogo charged it as well, would that work?

No, there simply is no ROM that supports concurrent charging. In fact both stock and custom ROM's block pogo changing when the Micro USB port is used.

OTG + Charging

Does anyone know if this is possible on our phones?

I know otg works but never had a cable where you could charge too

It should work since it's not different from charging on PC and copy files at the same time. Just need a cable with a split end; one socket for the charger and one for the OTG device.

I just tried it and it doesn't work. My phone won't charge at all using the split OTG cable, with OR without a usb device plugged in.
Tried every combination of plugging and unplugging things that I could think of, and no-go.
I guess it's possible that my split cable could be the problem, but this worked just fine on my GNex, so I highly doubt it.

Dang, it will be awhile before I get the OTG cable, also waiting for the N3 DE. Can anyone second this?

I agree. Tested with this cable, and it's a no go. Works without a single issue on my Gnex as well.
I'm leaning towards kernel compatibility.
Edit: Something that it does differently on the Note 3 is that it immediately gives a notification stating that a usb device is connected as soon as I plug it in, even without a usb drive being attached. While still connected, attaching a usb drive works perfectly.

Thanks, that's a show stopper to watch movies from a USB HD. Maybe a Samsung accessory cable will work; sucks for those already having one though.

Does it work with multiple attached devices?
I imagine that powers the attached devices but does not charge the phone battery?

i have tried and yes it will charge the phone. the one I have I got from walmart for somewhere around 10 bucks. it wasnt much

[Q] Nexus 7, i have a problem with power charging

My nexus 7 have a problem, that can turn o, every time rebooting, won't accept any charge, how can be?

...i have almost the same issue with my 2012 N7, stock&root....it just will not charge (tried different chargers!) It shows "charging" but it uncharges...now it is dead!!! ....a known issue??

Sounds to me like you either have a broken lead on one of the charging pins inside the MicroUSB charging port or either your battery has malfunctioned.
I also have the Nexus 7 2012(grouper) and have a "tighter" connection using my Samsung ATIV SE MicroUSB cable, but the cable for my Galaxy S4 tends to fall out easily.
Remember that most aftermarket MicroUSB cables do not have all the pins inside the connector and most MicroUSB Chargers only have the 5V charging pins..
Try plugging your tablet into a USB port on a computer and see what happens..
Hope everything works out!

I have changed my usb-port as well, and the battery icon when the tablet is shut off shows that it is charging, however the OS when turned on doesnt seem to recognize that the charging cable is present. Also PC connection doesnt seem to work... Any ideas?
