[Q] QI wireless OVERCHARGING? - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

So I just got my wireless pad and the wireless receiver. Is there any way that the Note 4 can overcharge and damage the unit if left on the pad charging even when it hits 100% ?

Nope, it'll drop to a trickle charge when it's full.

Samsung Wireless charger (wireless charging)

So i have noticed that with the Samsung wireless charger i got with my phone. That somehow the charger itself knows when the phone is fully charged or being charged.
Once the phone is fully charged the wireless charger stops charging. This is annoying because i put my phone on the wireless charger when i go to bed. Now when i wake up the phone is not at 100% because it stopped charging.
Also with my old LG wireless charger the phone does not want to work with it. It charges but the charge light on the charger is yellow indicating its slow charging.

Car charger: TF701 says "not charging"

Hi folks,
We're getting ready for a cross country trip. 2 kids, two tablets. One is a Samsung Tab 2 that charges via usb connected to a standard 12V-to-USB car charger just fine. The other tablet is an Asus TF701t. When connected to the regular USB cable for it, plugged into the 12V-to USB charger, it says "not charging." So I read up through Google and found the ASUS tabs have special requirements.
I just bought an: Asus Eee Pad Car Charger Power Adapter,36 pin 15V 1.2A Power Adapter Travel Car Charger for ASUS EeePad TF600 TF600T TF810C TF701T (Car Charger)
I plugged it in, and the tab still says "Not Charging."
Now, it IS charging a bit... despite the battery window saying not charging, I see the green timeline indicator that shows charging, and after a few minutes it went from 91% to 92%.
But I'm concerned this will be just a trickle of charging and not stand up to constant use. We've got two days of driving, 8 -10 hours per day, and this tab is my 8 year old's primary entertainment.
Given this is the official car charger for the tab, why won't it show proper charging?
My plan B is that the car does have a built-in 110V outlet. I could plug the wallwart into that (though, I need an extension cord, because the wallwart is too big to fit in the small recess where the 110V line is). I'm a bit worried the wall wart will pull too much juice through the 110V line and cause it to shut down (thermal protection).
Experiences or thoughts that might help me here?

Yeah sounds like it can't supply the correct voltage. More likely it is supplying 11V and the tab really wants 15V to charge. (Car batteries are 12V so unless it has some sort of transformer in it which is unlikely). So it will be a slower trickle charge.
Compare the car's inverter rating (the 110V outlet) with the input rating on the Asus charger. Mine wants 0.5A at anything from 100 to 240 volts, so if your car outlet is rated 120 watts or better it will do. If you are handy with a soldering iron there is a simple alternative: chop off a female USB cable and splice it into an automotive 12V power plug. Assuming your car's alternator and regulator are healthy (and of course battery) it will put out 14.0-14.5V at cruising speeds, perfect for charging Asus TFs. If your car has a 12V power outlet; many don't come with cig lighters anymore, but most have the same hole somewhere with a rubber plug in it. Word of warning though: make sure the kids don't plug the Samsung (or anything but a TF) into the modded 12V USB port, it will let the magic smoke out. They are only rated for 5V.
Turns out the car charger charged the tablet fine despite the not charging status. We started the trip at 9:30 with 75% charge. Two hours later, with constant game use, the tablet was nearly full. Stayed that way throughout the day's drive.
Thanks all.

qi wireless charge

i have a question
i am planning to buy a wireless charge and want to know something
if i buy the wireless charge where do i must look?
input or the output for more faster charging ?
example:
Wireless charging standard: Qi standard
Power: 10W
Wireless distance: 5mm
Input: 5V 2000mA
Output: 5V 1000mA
Frequency: 100-200 kHz
Power transform efficiency:> 75%
or dou have a link for a fastercharger already?
thank you
I have a wireless charger. It doesn't charge fast at all. You need a powerful charger to power the wireless dock. That's the 2000mA you see above.
I use a turbo charger to power my wireless dock. When connected to my phone directly, Ampere reports that it will reach up to 2200mA.
My phone now is at 50% charge and in the wireless dock charging wirelessly at 570mA.
Wireless charging is trickle charging only.

I am using several cheap QI-pads from eBay (China)
Use with standard usb-chargers (different types).
Disadvantage of QI-pads is that it's critical how the phone is placed on the pad.
Extra difficult with a Nexus 6. The back isn't flat.
With plastic material of a sleeping mat l've made a 'charging bed' that fits​ my Nexus 6.
I have a wide variety of Qi chargers scattered around the house, car, and office.
They all do an acceptable job of keeping my phone topped up throughout the day. None of them are even close to as fast as the QC 2.0 plug in chargers but that's not a problem for me. Because I can just set my phone down to charge anytime it is almost always fully charged.
Qi pad on my desk at work and night-stand at home. Phone is on it about 6-8 hours at night, and another 2-4 hours during the day. If my phone is below 50%, it will take a few hours to get back to 100%. But it is a great way to start the day at 100% charge without stress on teh USB port.

Wireless charging 2018 - Samsung Desk Top & Wireless Battery Packs?

Wireless charging 2018 - Samsung Desk Top & Wireless Battery Packs?
What's up with wireless charging in 2018? Especially Fast charging.
I will usually start charging when the phone get below 15% of battery.
If my Fast Charging wire plug will charge my Note 8 in 1.50 - 1.75hrs........ the Samsung wireless Convertible will charge the Note 8 in 2.5 - 3hrs ..........and wireless Battery Packs like the RavPower and Kuppet take 3.5 - 3.75hrs to charge the Note 8 to 100%. (Even though the RavPower says it will output 10W.) This just seems like very slow charging technology. I am not on planes and in airports so I do not have times where I am without a power outlet for more than two or so hours.
If I was in airports and flying a lot the Kuppet would be a must have device with the 20,000mAh and worth $39.99 but just as a wireless charger it simply is to slow to be of value to me.

Am I missing something here? I can fully wire charge my Note 8 in 1.5hrs at home, office and even car with the Fast Charging plugs. Why would I take almost double the time just to use wireless and buy those expensive ($40-$90) pads/stands?
What am I missing about the wireless charging value proposition?
Is the next step in wireless 15w output?

Any battery cases that charge the Note 9 via wireless charging?

My USB-C port on my Note 9 is broken so I'm reliant on Wireless charging the device. I would like to get a battery case for it but I am struggling to find out if any of them actually charge the phone via wireless charging? Some (like the Mophie) say that you can charge the battery pack by wireless charging but I don't think it will actually charge the Note 9 by wireless charging, I think it only does that through the USB-C port.
Are there any the will charge the note 9 via wireless charging?
This case does not charge the phone, but allows it to be wireless charged, and you can try to use this charger.

Thank you but I actually already have a case that allows the phone to be wireless charged and a wireless charger. What I am hoping to find is a case with a battery in it that will charge my phone via wireless charging. Something like this but one that will charge via wireless and not via the USB-C port.
