Max Wattage for Wireless Charging? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

I think the the fastest wireless charger Samsung has is that 15W wireless charging stand, but Huawei has this 27W wireless charger which is even greater than Samsung's own wired charger that came with the box. Question is, does the S20 Ultra support wireless charging that fast?

15w according to GSMArena https://www.gsmarena.com/samsung_galaxy_s20_ultra_5g-10040.php

15w, but do not that a 27w wireless charger outputs 27w but your phone won't receive 27w because of losses in inductance. 25w wired charging will be faster than 27w wireless charging.

The best option is to buy the 18W Duo charger or the single 9W charger. There are some tests on YouTube that prove 15W wireless and 45W wired charger to be nothing but a waste of money.

Has any used XIAOMI wireless charger?

Has any used XIAOMI wireless charger? The price is nice, how about for using it?
Not yet. Still on the way. The price is nice but the maximum charge of 7.5W is lower than other wireless chargers currently available on the market, like Samsung’s 9W Fast Charge Wireless Charging Stand or the 10W Anker Powerport. But I would also try.

Which is the better option for wireless charger ?

Hi,
Which option would be better for my Galaxy S10+,
Anker PowerWave 7.5 Fast or Huawei 15W Quick Wireless Charger ?

From the specs and price I would say the Huawei looks better. If it were me I would just go with a Samsung fast wireless charger. Amazon has them but make sure it's not a fake.
Huawei's wireless charger might not be compatible with Samsung's already very slow Wireless Fast Charge. I have a Xiaomi wireless charger that can charge up to 25W but it charged the S10+ at half the speed of a compatible wireless charger. The Samsung charger is better if you are going to purchase one that's branded by a phone maker. Of the two you are asking about the Anker is much more likely to be compatible with this phone and charge at the same speed as Samsung's charger.
Using an Anker one and everythings work fine
Samsung has their own wireless charger that charges at 15W (Android) 7.5W (iPhone) . Highest output on the market right now

Highest possible wattage for wireless car charger? All I see is 10watt. No 15watt+?

Highest possible wattage for wireless car charger? All I see is 10watt. No 15watt+?
All the wireless car chargers seems to only have 10watt for Notes, looks like 15watt for LG phones. samsung makes a 15watt wireless chargers stand so thought this would be possible for car chargers.
has anybody seen a wireless car charger that will charge a note 10 with more than 10watts?
thanks in advance

Hey .. I tried some of car wireless charger with 15 W .
There is only one working well for me .. it's giving me fast wireless charger when it connected .
But you have to buy also car charger which is support QC 3 to deliver that power to wireless charger.
You can find it in Amazon : CHOETECH 15W Wireless Car Charger Mount,15W/10W/7.5W Windshield Dash Vent QI Fast Charging Phone Holder Electric Auto Clamping

well the charger is 20watts, but it won't charge the note 10 at 20watts
so 52$ to do what a $15 charger can do

Samsung s20 wireless charging?

So I just bought the Mi Fast wireless charger 20w which comes with a 27w power adapter, but when I tried to charge the phone it says only "Wireless charging" not "Fast wireless charging" I've checked charging settings all types of charging are enabled, also when i connected the 27w power adapter no super fast charging again.. it's just charging it slowly.. any ideas??
S20 is just not compitable with this charger so it will only charge at 5w , s20 supports Qi/PMA wireless charging standard , so to get fast wireless charging you should buy Qi/PMA wireless charger with 15 w max output
Interesting. I have a Mi 10000mah power bank with wireless charging. Was able to get fast wireless charging on my s20+

Wireless charging issues

My wife has a LETSCOM wireless charger, that she uses without issue with her Pixel 3. It works intermittently with my Pixel 5, and I can't work out why. Often, when I put my P5 on it, the charger flashes red/blue - according to the user guide, this is "overcurrent protection". If I reboot the P5 or unplug / replug in the charger, the charger stays blue, charges the P5 with no issues. More often than not, I get the "overcurrent" issue though. I've plugged the charger into my P5 charger, using the P5 USB cable. Any thoughts?

FWIW I have an Anker wireless 10W Fast-Charging PowerWave Pad and while it fast charges other phones (S10e, and other Samsung phones).
I tried it with the Pixel 5 and it says "charging slowly". A pity really as I think it's one of the best reasonable wireless chargers out there.

Are you using the same wall plug when trying different devices on it? For the Pixel 5 to fast charge, your wall plug needs to be 9V/2A at least 18W and the pad needs to support or to be within spec of the Qi 15W Extended Power Profile, which should then allow it to fast charge on your pad at 10W. If its under 18W wall plug or only say 5V/2A, then it wont fast wireless charge the Pixel 5 due to that 15W EPP afaik :good:
Also, the Pixel 5 has max 12W wireless charging, but most pads will usually drop down if its a 15W pad for example, from 15W to 10W to 7W, 5W - or thereabouts, so I'm not sure we'll get anything above 10W wireless unless its a specific 12W pad. From my understanding at least

I'm using the Anker recommended wall plug. I don't have enough posts to provide a link in comment but its title on Amazon is "Quick Charge 3.0, Anker 18W USB Wall Charger PowerPort+1(Quick Charge 2.0 Compatible, Qualcomm Certified) for Galaxy S8/S7/S6/Edge/Plus, Note 5/4, LG G4, HTC One A9/M9, Nexus 6, iPhone, iPad and More".

ah I see, so this device is QuickCharge 3, however it does not support Qualcomm's Extended Power Profile by the looks of it, so it wont fast charge any of the Pixel devices, they require EPP standard and for 10W wireless charging on the pixel 5, it must be at least 18W 9V/2A + minimum 15W EPP.
The PowerWave Pad itself looks to only use 10W Fast Charging when using a 9V/2A wall plug (which is fine for Samsung devices using QC2 or 3), however, it won't fast charge the Pixel in the same way without being certified for Qualcomm Extended Power Profile. So your Pixel will only charge at 5W on it unfortunately.
Yep! Was disappointed. I'm unsure of which non Google brand wireless chargers will wirelessly charge this thing faster than "charging slowly"
Jeez, it's a compatibility nightmare! If anyone has a fast charging wireless solution for P5, please let us know!
This works for me:
