I just recently picked up an OTG Y cable off Amazon for a couple bucks, however it's practically useless as it charges the phone at a rate slower than even a regular USB charge. Perhaps this is just the nature of charging while using host mode, but could anyone clarify.
If this isn't just the nature of charging while using host mode, can anyone suggest a good quality OTG Y cable?
Just wondering if you have a kernel supporting fast charge with OTG. The cheap OTG Y cable ( http://www.amazon.com/Micro-Cable-Power-Galaxy-Samsung/dp/B00CXAC1ZW/ref=pd_cp_pc_0) I'd purchased for my N4 does do fast charge with N5 and ElementalX.

Ive since moved on from the atrix but kept the lapdock to see if i can use it for a hdmi monitor and charger. I now have the galaxy nexus and wanted try and use the lapdock with it. Im going to order the MHL adapter for the galaxy nexus to connect to the lapdock's hdmi with a female micro hdmi adapter. Ive read that the lapdock can receive HDMI input from other sources besides the atrix but will the lapdock accept HDMI source from a MHL adapter. Another problem is that in order for the Samsung MHL adapter to work it needs to be plugged in to a micro usb power source. I need to be able to use the micro usb from the lapdock if i want this set up to be portable.
i bought a micro usb extension and tried that but it doesnt charge galaxy nexus or Optimus P500. Unfortunately i sold my atrix before i got the cable so i cant test it with that but the micro usb extension charges all my phones fine when plugged into an AC adapter. So is it possible to mod the lapdock or micro hdmi cable to charge my other phones?
I can't speak for different phones made by different manufacturers (samsung, etc), but the atrix lapdock can be modified to work with other motorola weptop enabled phones. I am typing this on an atrix lapdock plugged into my Droid 4. I had to modify it when i bought it in order for it to work, but it was a simple 10 min job and it has been working well!
All I had to do was unscrew the cover of the hdmi/microusb ports, and flip over the connectors that were upside down for my use, and put it back together. A bit of shaving the plastic in the corners was necessary, but was not difficult. I am a happy user since this keyboard is a bit larger than the lapdock 100, and it was cheaper on craigslist than a lapdock 100.
Now I just need to see if anybody has managed to find any happy ways to hack/modify the atrix lapdock for greater functionality, like multitouch or scroll areas. If you have happened to see someone getting this to work, please do tell!

no need to mod!!! there are two powered usb ports on the back of the unit. when it senses hdmi, it turns on the usb ports and you can charge or power your usb device assuming 500ma is enough. not sure what it outputs, but it does charge a phone.
Where i can buy the lapdock charger?

I I am looking to put a little charging station in the storage compartment of my home theater sectional. I really would like to only run one USB cable to charge my devices. I am a bit worried I will not be buying the correct pieces for my needs. I bought a 16ft. pluggable USB cord on Amazon recently, but there seem to be worries that a single USB cable may not provide more than 2.1a.
I would like to charge at least two smartphones (HTC One X and Note 2) at once and at their full charging rate. Assuming that this is even possible, could someone provide me with a wall adapter and USB hub that will work for this? I like the looks of...
PowerGen Dual USB 3.1A 15w Travel Wall Charger
and
AmazonBasics USB 2.0 4-Port Ultra Mini Hub
(I can't post links yet).
If this is an impossible task, what are some other good options? I looked at the Belkin Valet, but it appears too large, and has some issues.
Well a note 2 alone takes more than a standard usb 2.0 cord to charge at full speed. Maybe try a usb 3.0 hub and tablet wall charger. Not 100% sure its possible though

Okay, that makes it sound like I might want to change my mind about this whole one USB cord plan. How about running an extension cord instead of a USB cord, then hooking it up to a dual USB wall charger like this-
Kensington AbsolutePower Dual 2.1A USB Wall Charger (Amazon)
Would that work for two Note 2s?
If it can charge 2 ipads then it can charge 2 note ii's
Unfortunately, I just wasted over $30 on a Valarm IoT OTG Y cable. It does not work at all as a host cable for any USB device on the G4. I was hoping to use the Valarm cable to connect a USB DAC and charge the phone at the same time. The cable will let me charge the phone but whatever I connected to the USB female port is not recognized. If anyone finds a USB host cable that allows charging, please post!

From what i understand otg goes one way or the other it cant act as a host and carge at the same time. It flips the charging circut to flow out instead of in. Ive been through this on a few phones tried even straight wiring a powerline to the otg itll power the usb device but not charge the phone.

The manufacturer of that cable clearly states that it'll charge a samsung phone, not confirmed working on a G4 though. Here is the link, http://shop.valarm.net/products/micro-usb-host-otg-y-cable-with-micro-usb-power-for-samsung
I wish there was a way to enable charging using OTG.

Yea me to i have a few devices that hook to my car that drain my tablet and phone batts and it kills me the only other way ive got it to work is hard wire a charger to the phone. But of coarse this is a old throw away gs3 that im talkin bout not my g4. I havnt tried on my g4 yet but its all phone specs has to have dual charging circuts cause they can only flow one at a time. Now some new devices i know. Do support otg with charging capabilities.
This is BC Master USB Type-C to HDMI Female Adapter is the "Swiss army" adapter because of all it does for me. I own a Google ChromeBook Pixel and USB ports are at a minimum plus im constantly streaming to the TV so this is the perfect solution for me as it fixes 3 of my issues with the Pixel. I also just ordered a Motorola z force which uses USB TYPE-C so I will be also using this adapter on that device and one feature that puts this adapter ahead of others is the PD port which I know I will be using with Moto Z to be able to charge the phone while I am using it while using the adapter. The BC Master USB Type-C to HDMI Female Adapter has 4 USB 3.0 ports for SuperSpeed data transferring of up to 5 Gbps and downward compatible with USB 2.0/1.1 specifications and supports high resolution up to 4K . Another feature I dont see on other units I compared this to was it also supports high definition audio including SACD, DVD-Audio which I liked for gaming. This adapter is Bus-Powered, so no additional power adapter needed and supports hot swapping & plug-and-play and for safety has a built-in surge protector incorporated to safeguard your USB devices. Overall im very happy after using this for over a month and never thought I would use it as much as I do but it really comes in handy in some way everyday. Its priced at $35.59 HERE and comes with a 24 months warranty.

I purchased this vehicle fast charger for my Note 5 and it works great to fast charge my Note 5. It has a coiled cord, which I really like, and an LED light that helps you to see at night that you are orienting the micro USB plug properly. It is OOS on Verizon:

But It looks identical to this one on Amazon with a 2 year warranty:

I purchased this $10 micro USB to USB C adapter to use with the vehicle fast charger I already have and it works great to fast charge my S8+. I like that I can have both a micro USB and USB C charger in one since my bluetooth earpieces are all micro USB. The laynard makes it nice to stay attached to the charger so I don't have to go looking for it.

Looks like they sell it on Amazon too:
https://www.amazon.com/Verizon-Micro-USB-Type-C-Adapter/dp/B01MU9DF60
It's a bit pricey at $10 but it works to fast charge my S8+ so I didn't have to buy a new charger and it also allows me to have 1 charger in my car for all of my devices.
If you have Amazon Prime and get both the vehicle fast charger for $14 and the adapter for $10, it would come to $24, which is not bad for a vehicle fast charger that can charge both micro USB and USB C devices. The coiled cord is really nice IMO and so is the LED light for when you are charging a micro USB device.
