[Q] Does the G-Tab not charge off USB? - G Tablet Q&A, Help & Troubleshooting

It doesn't look like it to me. Is this true? This would be a show-stopper for me. Thanks.

Found the answer: No.

Well that sucks.

If it's any consolation, neither does the Xoom. I think once you hit the larger tablet form factor, you can expect USB charging to go out the window.

Yeah, 5V DC at less than an amp is only supplying around 4.5 watts of charging power. You're looking at 7 hours or thereabouts to charge via USB. If it's any further consolation, the iPad can charge via USB, but only high power USB or when it is asleep. It will still take a long time. Still, it would be nice to have the option even just to keep it topped off while near the computer.

Amen!
Anyway I find the overall battery performance on the G tab pleasing!

What about something like this?
I have 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_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
which is powered externally via 5V DC at 3A amps. It has USB ports on the bottom and even comes with a USB-to-DC adapter for the Sony e-Reader.
Since this isn't a regular computer USB port (I guess), could this type of setup theoretically work with the GTab and, if so, is there some type of USB-to-DC cable that would work?

[Q] Mini HDMI swivel cable/adapter

Hello there,
I wonder how the mini-hdmi slot feels like when a cable is plugged in and the tablet is in your hands : the slot is on the right, and it seems like the connection is going to be quite fragile if you try to play an accelerometer based game with this cable leaving the tablet at 90 degrees and having all the weight of the cable until it reaches the floor to get to the tv applying force down on the little connection...
this is why I'm trying to find a robust mini-hdmi to hdmi swivel adapter. 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_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
but mini-hdmi to hdmi.
Does someone have an idea ? Does this exist ? Am I looking for something not necessary ? (I don't have the pad yet as it should come to France by the beginning of May)
Cheers,
Sgspikes
Most mini hdmi to hdmi cables aren't the thickest things in the world. The cable should be able to handle the torsion easily way before the connection. As long as its a camera type hdmi cable and not a bulky thick cable.
You could use that very cable and add a HDMI to Mini (or Micro) HDMI adapter. They're available on amazon for a few dollars
I got one of these and it worls well so far.

I contacted Samsung and this is their reply
Thank you for contacting Samsung. I apologise that you have been unable to locate the requested information about your GS3, I understand this can be frustrating.
Inregards to your previous email, when you are charging your GS3 by usb with the phone switched on the power usuage of the GS3 is only slightly less than what the usb lead can charge the phone at so it will take longer to charge.
When the GS3 in charged by the mains there is more power running to Phone and will charge more quickly
If you require any further assistance, please contact Samsung again and we will be more than happy to help.
Kind regards,
Gavin

Basically not answering my issue as to whether the phone has an issue.
Try a different USB cable or charger.

I have tried two pc's and two cables and the same result with both.
If i use both cables with the AC charger they both work fine and as i mentioned is OP my HD2 running ICS charges to 100% in about 5 hrs where as the GS3 is nearly 4 days using same cables/pc.

You guys should totally get a [near-]free USB dongle...

I think the picture says enough:

Note that everything is on, and it's all connected, powered, and recognized by the LTE.
- 480Mbps hi-speed USB Hub
- 3TB Hitachi USB 3.0 Hard drive
- SanDisk Cruzer 32GB flash stick
- Inland Pro wireless mouse & keyboard combo dongle
- Generic USB fan (not recognized by the LTE, but it's not supposed to be -- it works fine)
- Powering everything but the cat, but the process seemed to energize him too
All of these are operating simultaneously in the picture. You can see the fan revolving, the the sandisk processing (red behind the slider), the big hard drive chugging (blue light), the hub operational, ...the keyboard and mouse worked fine but there's no way to show it in a pic, so you'll have to take it on blind faith.
What was this thing's max power output again? Surely this can't be healthy for the battery (or circuitry) in any case.
Welcome to kickstand tablet 2.0 heaven. You may check your sanity in at the door. /nerdgasm
Hmmm.... You know it took me awhile to figure it all out and that's a cool pic man. Can u try and get the whole cat next time? Idk what the rest of that crap you're talking about does.
Jk. Nice setup. I like black cats too is all.

Okay I have to admit that isn't worth the money.
Which one did you get though???
Sent from my D6503 using XDA Free mobile app
something like the first one.
but i really wonder WHY it does that!
I mean... i used the original Sony Wallcharger! 1.5A and just pluged it (with the sony cable) in the back of the charger!
Then the phone wen't out of battery and died... restartet after 5 minutes, and then i booted into the OS.
Thats the only reason i can imagine why it would charge so slowy. i mean.. i used exact that same wall charger via microUSB and it worked fast and fine!
i mean, how the hell would they limit the Ampere flowing trough the dock ? some included resistors?
If i have to much time i'll try and open it. but i could swear the cheapest way would be a simple (two...) from the microUSB port to the magnets. And this is chinaware! gotta be the cheapest way!

Question Addtional/Replacement fast charger

Do I have to use a branded Asus charger to get the fast charge? I'm using an old Huawei one and I don't seem to get the faster charging as I did on my P30 Pro.
Looking to purchase a 2nd, smaller charger if there is a compatible one?
I guess any QC3 or PD charger should work.
Will this give me the fast charge I'm after?
PD3.0 PPS or QC 4.0 will according to Specification.
A friend of mine with ZF9 tells me that even with original Asus charger and cable it appears the "Hypercharge" text on the phone, but the real charging speed is slow; anyone else with the same issue? Thanks!
most battery management will only charge fast when the battery is almost fully drained, generally following this curve. You'll see like 5W or something when closer to 90% battery, even on silly charging protocols like SuperVOOC. https://www.androidauthority.com/fast-charging-explained-2-889780/

I know this, is not the first phone with fast charge that I see, and my friend too is not so noob.
So, the problem appears on his phone even with battery on very low percentage.
