[Q] Laptop doesn't charge tablet

My laptop recognizes my GT-P6210, and has even before downloading Kies but it won't charge the device.
I downloaded the Kies drivers here: http://www.samsung.com/us/support/owners/product/GT-P6210MAYXAR#content2
It appears that the above is the only drivers...that I could find at least. Does anyone know what the problem could be? Does the laptop just not charge the device?
Thanks

Computers cannot charge the G tab, unless you have a charging cable or an adapter. They can be obtained from eBay.

i think it might charge, just really slowly

No it definitely does not charge, since a little red X appears on the battery when I connect it.
Thank you both!

wrong.. it charges but super slow.

try esata/usb port
On my laptop it does charge very slowly. For best results lock the screen and use the esata/usb combo port if you've got one. Seems to produce more power

It's normal that a PC or a Notebook can't charge a tab unless u have special usb-port that has a higher output.

I have higher output USB ports but it's still just a trickle charge on the tablet. My cell phone charges fast using the same ports.

Usually cell phones have 1000-2000 mAh. The Samsung Galaxy tab 7.0 plus is 4000 mAh. It charges, but a a very, very low pace. The greater the battery, the longer it takes. And on top of that, the system is always draining the battery, even when the screen is off, and with more demanding processors, the greater the consumption. Just think of the new Ipad, there are already reviews that advise that charging it through usb port is not practical at all. Please, I'm not starting a flame here, just pointing out that fact. In fact, very likely the Android tablet will follow the same path, given that the future is quad-core and even more cores. May be this will be solved with usb 3 that promises greater voltage (or amps, I'm not sure).

I use USB 3.0 ports for charging, tablet is a trickle charge, phone charges fast.

actually it is charging, the x symbol/logo just to remind you that charging using usb is not effective and very slow.

Yeah. Mine too. It shows a Red "X" till I read somewhere in XDA forums (can't recall where exactly) that we can get a special cable to do the charge.

charging using regular charger

Just wondering if charging the phone using regular charger instead of using the fast charger that the phone ones with will mess up the battery?
For example when in my car, Can I use the car charger to charge the phone?

not really, but for sure will a bit slower than the fast charger(actually not a big big different, becoz I'm using the charger from my previous Note 7), and for the fast charger need to go together with the original cable which can go to 5A, now mostly we can buy is support 3A max only.

I've got a normal charger from an old Asus tablet next to my bed I don't see the point in fast charging it overnight I have an idea in the back of my head that it might last a bit longer if I'm not charging it at supercharged speeds every night. In fact I plan to only use the supercharger as a top up only when I need it and in a more convenient place than next to my bed. I've tried 3 different charges now I know I'll charge no problems, albeit much slower

Google Pixel charger and cables with P30 Pro??

I haven't been able to find an answer online through google searches. Does anyone know if it is safe to use the charger block and USB-c cable from a Pixel 1 or 2 to charge a Huawei P30 pro?
Would be a shame to need to toss the stuff I already have. But I know USB-c can carry alot of power and I dont want to wreck anything.
Thank you for your time.

My understanding is that you can use any USB C charger with the P30 Pro but that you won't get Supercharge unless you use a Supercharger and a Huawei cable (with the purple colour in the USB-A connector).
The official Pixel and Pixel charger shouldn't cause any damage - surely Huawei has an obligation that their device conforms to USB C standards?

As much as i get it u can use any cable but i think u wont get supercharge speed. So i dont think it will harm your device but u wont get supercharging benefit of it.

According to what I found searching online:
The Google Pixel comes with its own USB Power Delivery based charger that supports 15 watts (5 volts @ 3 amps) and 18 watts (9 volts @ 2 amps).
The P30 Pro's charger uses 10 volts @ 4 amps (40 watts) to supercharge.
Since the Pixel's charger doesn't exceed the P30 Pro's charger output there won't be any problems using it with the P30 Pro, but you won't be able to supercharge your phone with it.
Just like the previous posts stated, also Type-C chargers (at least the good ones) should put out a standard charge of 5 volts @ 2 or 2.1 amps when used with phones that are not compatible with their quick charging technology. Non-Huawei 4 amps capable cables should work for supercharging when paired with a Huawei supercharger. I am currently unaware if there are any aftermarket chargers compatible with supercharging but given the odds there might as well be some out there.

Cheapo $9 EBAY Generic Desktop Stand - Fast Charging 13w + working w/Samsung AC/USB

Cheap! $9.00 (20w) Generic Desktop Fast Charging Stand (Working w/NON OEM AC USB) including SAMSUNG Fast Wireless AC / USB
___________________
First let me say I have absolute ZERO affiliation to anything relating the sale of this product!
I am just sharing the wealth here for as being still such an unclarity on proper working charging accessories. A small gamble I took on purchasing (2) of these cheapies on EBAY turned out to be quite
a surprise.

Using with GP4XL (Unlocked)
• Fast Wireless Charging (13.2w confirmed)
• Charger immediately recognized on device (as PIXEL STAND) enabling additional GOOGLE ASSISTANT software
• Working w/various GENERIC AC Adapters & USB cables (YAY!)
including SAMSUNG FAST WIRELESS AC / USB + more
• No issues of overheating or phone getting warm.
I am unsure if the specs are EPP charging (as a listed requirement of FAST CHARGING via Google) though it seems to be doing the job as if it was.
What I did find ODD is that these chargers DO NOT play nice using the GENUINE AC Adapter & USB C cable that shipped with the PIXEL 4. SLOW CHARGING AT MAX! Go Figure?
I have tested various older USB cables and USB C adapters and all with no issues w/Fast Charging (though obviously keep in mind results do vary with stuff like this!)
Regardless, for $9 bux, its worth checking out for anyone who is interested.

If what you're saying is true then this is a Pixel stand for a fraction of the cost. That's pretty awesome.

for 10 bucks I'll give it a try. Worse comes to worse I can use it to charge other phones in the house.

I have one on the way from China. Will report back when it arrives.

Dumb question: does the generic AC USB plug being used with this stand still need to be USB-PD capable?

I think it only needs to be quick charge 2.0/3.0 capable. Didn't the OP say he had trouble using the original pixel charger that came with his phone? I actually ran into issues using my original pixel wall charger with some wireless car charger mounts. They worked fine with QC chargers.

I ordered one too for 10 bucks it's worth a try.

They sent two of these to me. Both show max 8.4 watts no matter what cable/plug I use and I have many. It also does not present itself as a Pixel Stand - those features are not available.
To add, I noticed the stands get in a state that bounces power on/off very quickly and doesn't stop. I would avoid these.

What do you mean it bounces on and off? Like it says charging and then says it's not charging at the bottom?

Yes, bouncing like a bad port on a router/switch. It goes from charging/not charging very quickly over and over after about 3-5 minutes of charging.

mine arrived today, I can also confirm slow charging and no pixel stand functionality no matter what adapter or cable I use

Sorry for any delayed responses here (holiday) though I have just caught these testing results.
I just received an additional (2) of the same chargers and all seem to charge fine here. (Pixel 4 XL)
All being used with Samsung AC Fast Charging AC adapter.
Check to see if the AC adapter you are using has both 5v & 9v output. (Must have 9v for the FAST to charge)
-
Can you post a photo of the AC adapter that you are using ? (all photos could be of assistance here.)
The stand itself is 20w so fast charging would more or less come down to the AC plug.
** Keep in mind that the OG cable and AC charger plug that came with the PIXEL phone is not compatible
with this charger that will hit at SLOW. (mentioned in OG post)

I tried several, from the OEM to choetech to aukey to zte. I used the cable it came with, OEM a to c, OEM c, third party c; i tried both type c and qc3 chargers...all with no success. I wouldn't think the pixel stand feature shouldn't have anything to do with charging speed, though I can't say for sure

I believe the PIXEL stand software features only become enabled when detecting a FAST CHARGE at 13.5w.
(which is capable when using AC adapters of 9v & more)
The only AC adapter I personally have found to be non working was THE OG stuff & USB C to USB C
Most USB C to USB A seemed to work with no hitch.
USB C adapters, had no issues with them either. worked fine.
Can you snap of picture of the AC adapter labels. ?
See if we could narrow down the issues.
also one last .... check the actual charging wattage using the app Inware. (Battery Tab)
The lock screen charging message will ONLY show Charging Wireless - not rapid charging (which is easily misleading) though is running at FAST WIRELESS CHARGING speeds.

Using with LG stylo 5 fast adapter and the chargingspeed is fast. between 1 1/2 hours - 2 hours total. Using with Usb C to Usb A cable 3 ft.
My only issue really was trying to get the extra software up and running. I couldn't figure out why or how to do it. strange as I moved my pixel phone upwards while resting on the dock all of a sudden it just appeared out of nowhere to activate all the extras. weird device for sure but works.

---- II personally didnt even know there was such software initially for as it only showed up about an hour later sitting on the charger. Please let us know how it all goes and if you have any trouble along the way.
Knowing they are knock offs, I am kind of curious to see what the long run holds. Thanks for the info.

forgot to ask, can you share the specs of your LG charger for us ? All the info helps build the list of do's and donts. Thanks..

I am using the original lg fast adapter plug.
9.0v 1.8amps and 5.0v 1.8 amps. working well with stand.

I ordered a pair of these stands as well and am still waiting for them.
But I did order this one before that from amazon https://www.amazon.ca/gp/product/B07Y9J68TC
and it also gets recognized as a pixel stand. (only when using samsung or QC3 adapters though)

Charging at faster speeds using thunderbolt 3 port

Guys, I've been using a one plus 7 pro since 2 years. During these days I've noticed something, when I charge my phone using the red usb cable by connecting to laptop it shows about 1250mA speed. Which is slow. But, when I do the same using a type C cable by connecting to thunderbolt 3 port on laptop, it's speed is around 1900mA, much higher..!
Now, we all know a thunderbolt 3 port is capable of providing as high as 100W charging speed. Our one plus 7 pro wall charger only gives 30w at peak charging speed.
Hope everyone understand where I'm heading!
Why can't we get the max charging speed(in my case 30w aka 6000mA) with this setup ??
Is it that, one plus device is failing to recognize that thunderbolt 3 it's connected to is able to supply required power ?
Or is it because the cable I'm using , inorder to achieve this insane speeds, has to be a thunderbolt 3 compatible one?(which in my case, isn't)
Please share your knowledge, do let us know if someone found a way out to make it possible. If yes, that would mean I can completely stay away from that heavy brick for charging..
