Question Compatible 15w wireless chargers? - Samsung Galaxy S21 Ultra

Hi guys,
I've noticed Samsung S21 ultra supports 15w wireless charging - I was just wondering if all 15w wireless chargers were compatible? Or whether they specifically have to support "Samsung fast charge 2.0" - like the official chargers?
Wondering what others have bought? Let me know! Thanks!

I've been doing some research, I know that Samsung devices are supported by QC 3.0... but just wondered if this is true for wireless charging? Will generic 15w wireless chargers work? Would be much cheaper!

While generic 15w chargers will work, there are other factors that needs to be considered. Such as what kind of brick you are using with the charger and things like how thick the case you are using.
Sammy only have one 15w charger and that is OG stand. The other sammy fast wireless charger is 9w (input still requires 15w though)
Can't comment whether which 15w is reliable or not as they are 3rd party and varies from company to company.

A fair point. I guess if you use a QC 3.0 brick with at least 15w output - with a 15w wireless charging pad it should theoretically work then?
Be interesting to see which ones people find works for them!

Probably works but wireless charging is inefficient and needlessly raises the battery temp which is detrimental to its longevity in the long run.

An 8 W Samsung wireless charger does not heat up the S21 ultra more than the 15 W charger I have (this cames with my Note 9). I would think a 25 Watt charger would heat it up more. The reason I bought the wireless charger was for my Note 9 and now the S21 ultra is that my Note 9, despite considerable babying, is showing some issues with the socket (it often will show cable charging instead of fast charging and despite changing cables, cleaning out the socket with compressed air and a toothbrush etc). So yes, in general you are correct but socket wear must not be discounted.

I hear what you're saying about the port. I do a lot of partial midrange charges so 3-4 times a day isn't uncommon.
The biggest thing is not to hit/drop it when a cable is connected.
Battery or port assembly the phone needs to come apart...

I have a couple of these wireless chargers. Mine are an older version that don't have a USB plug at the charging pad (mine has a non-removable wire from the pad). I can't seem to find specs on their site now, but when I bought mine they claimed they were 15w. I only bought them for how they look. I personally don't care how fast they charge, I prefer slow charging for better battey life, I'll use wired chaging when I need something faster. I have fast wireless charging disabled on my phone. But I just checked it, if I enable it, it does say "fast wieless charging" on the sceen when I place it on the pad, and the time to full charge is a little quicker than with fast wireless charging disabled. Still not as fast as wired though.

So the best way to check this is to download Ampere!
Grab it from Google play store, install it, and then open it while you are charging the phone on different wireless pads.
You work out the Watts by using;
Amps x Voltage
Let me know how it goes!

Wireless 3.0 Charger recomendations?

WHat is a good wireless charger for the Edge phone? I prefer not to alway connect with the cable......
Choetech has a few fast wireless chargers listed on Amazon.
1: Single Coil - Pad-type
2: Single Coil - Circle-type with Smart Lighting
3: 3 Coils - Pad-type with Smart Lighting
I was researching this yesterday. What you have to remember about wireless pads is that typically a 2.0 pad will charge similar to a Non fast Charge 2 plugin-in charger. So like a standard charger. Once 3.0 ones are out I assume it will be a similar scenario. Hopefully some day down the line they will be just as fast as their plugin counterparts.
As far as those links above, 10w max isn't very strong considering a plugin 3.0 is about 18w and even a 2.0 is 15w. So 10 watt seems pretty dinky for a wireless still. Still I guess better than the old 5 watt ones.
Tronsmart is making a fast charging capable qi charger which should be nice. I used to have a TYLT VU (angled qi charger) for my Nexus 6 that as great. I would buy an angled one because it's easier to see your phone on and impossible to not have it charge.

After some more digging I found this: Nekteck Wireless Charging Pad (18w QC 2.0 Adaptive)
Looks very promising; 18w, slightly tilted instead of laying down flat, smart lighting.

It does look nice, but it is just the pad, correct, you still need to use your own samsung charger?

Correct. You can also buy a "QC 2.0 Adaptive Fast Charger" like this.
please use the Samsung original or certified third-party 18W QC 2.0 adapter as its power source.
Already got one on order so maybe will get this too. Keep in mind that still this will NOT charge as fast as a 3.0 18w direct plug. Not sure why that ends up being the case, but that is what I have read.
BUT::: Lower down on the order page it say:
"Fast Charge Model(10W Output Max) ONLY "
So does that mean if you have an 18w source it still only delivers 10w to the phone? Seems hardly worth it. I sent them an inquiry about this. (it's not listed on their website)

I received that charger 3 days ago.
I can not test it on the S7 just yet of course, however I have tested it on other phones and it does charge faster than a standard Qi wireless charger does.
I will post up some information about this charger, and the Cheotech 10w circle fast charger that I have also, as soon as the phones arrive.

if you could do a compare with the plug-in 2.0 charger, that would be great.
Hi guys, I'm new to wireless charging, and I'm a bit confused as to which wireless fast charger I should buy for the S7...is there anything different about the wireless charging on the S7 than the S6, Note 5, etc.? Are there new chargers coming out soon that are somehow better than the ones currently on the market? I'm just wondering which charging pads would give me the fastest charge. If anyone could shed some light on this for me, that'd be helpful
Here is what i got for our Note 5's, my wife and I both have one. They have worked great so far. You need to use your Samsung fast charging adapter with it. For $19.99 I could not be happier.

My Choetech fast wireless charging pad still works great so far. I will recommend Choetech. Very stable and warm slightly. They have many kinds of wireless chargers, which has lots of good feedbacks on Amazon. :good:
Well now that there is a report that the s7 and s7e do not support quick charge 3.0 (sad) I'm not sure what's what.
I have this one: www.amazon.com/Wireless-Charging-Pad-CHOE-Qi-Enabled-Adaptive/dp/B016DAFUGY
Works REALLY well for me, charges a lot faster than the old Nokia DT-900 pads I have scattered around the house. Choetech is sending me their newest model to test, so I'll have a writeup for it here soon. Maybe a week or so?

That looks like a good one. I have a pad already, If I use one of the new power supplies will the charge fast, or need to upgrade the pad????
You'll need to use a Quickcharge 2.0 plug, to have it fast charge. It's not going to go any faster if you use a QC 3.0 unit though.
This is what I have now

So Samsung new wireless charger is not the fastest you can find? (Qi 15W?)

So I found this article http://www.cio.com/article/3035071/...dge-support-15w-qi-wireless-charging-but.html
It seems like Samsung's new charger is not 15W standard?
I also found this product that shows a 15W standard wireless charger. I barely find any information about 15W Qi charger, such as the heat, charging efficiency etc. http://www.incipio.com/ces2016/ces-power/ghost-15w-qi-fast-wireless-charging-pad.html
3 times faster sounds very attempting.
Does anyone has any information related to the 15W wireless charger, does it heat up the device even more?
That incipio charger can't come out fast enough. By 2nd Qtr I'll be used to my Samsung wireless charging.
Just remember that the higher the wattage, the more heat is going to be generated. Wireless chargers already generate a lot of heat. I can't imagine how hot the phone is going to get with a 15 watt charger. There may be a very good reason Samsung is limiting the power of their charger.

If they were that concerned with what they wouldn't support the 15aw standard, but they do. Qi charging doesn't always make the phone that hot compared to quick charging. I have a Choetech fast qi charger (only 10W) I was sent to review and the phone is at about this same temperature as it is via QC 2.0 with a cable

Does the Mix ship with a 3.0 fast charger?

This is something i haven't seen mentioned or confirmed in all the reviews i have read. I have read reviews of other xiaomi devices that said it was qc 3.0 enabled, but the charger that ships with the phone is not a quick charger and the user would have to buy their own to take advantage of this feature.
so does anyone know if the charger we receive with the mix is in fact a quick charger as the mi mix is on the devices that is qualcomm quick charge 3.0 enabled.

That site quoted 83% in 30mins, I am not getting that, not even close. I bought the anker USB C quick charge charger which suppose to be quick. I don't feel quick at all...
Anyone also bought charger that can comment on this?

yes, as i posted i am well aware the phone is quick charge 3.0 capable. my question though is the charger that ships with the phone a quick charge charger. there are other xiaomi phones that are also quick charge but the user has to provide their own quick charger.
if i were to guess i do not think this charger is a quick charger based on my results compared to my nexus 6.

I got an Aukey QC3 5-Port Charger.
I'm trying to get my device empty right now (tough though as it lasts pretty long) and will test it afterwards.
Gesendet von meinem MIX mit Tapatalk
I compared the included charger with my Anker quick charge 3 charger using the Ampere app.
The given stats were marginally better with the included charger.
I'm not really sure what all the figures mean but they were there or there abouts the same, the Anker charger is Qualcom QC3 certified.
Not nearly getting the quoted charge times though with either charger.
At 53% it claimed 44 mins to 100%
Yes, it ships with a fast charger. It delivers:
5V - 2.5A (12,5W)
9V - 2A (18W)
12V - 1.5A (18W)
So yes, it's a QC2.0 fast charger.
I'm currently at 69% and on the normal charger it's 3 hours+, on the QC2.0 charger I have, it's 1.5 hours and it gave me the same for the included charger. Kind of disappointed that it's only 2.0.
after seeing how insane the battery life is on this phone i just went with the qi wireless charging usb C adapter and I have no plans on going back, works awesome.

What I dislike, and you can't use is the Wireless Charging with your phone and case, and a metal plate stuck to the back of the phone. You see, I really like the various magnetic holders in the car (I have one that works with the CD Slot of the vehicle to mount the holder, another that is a little ball mount that sticks to any flat service). They use a thin metal plate to mount to the back of the phone case, and the magnetic is part of the phone mount that is in the vehicle. If you place the phone with the holder and the metal plate on the wireless charger base, it will overheat both the charging base and the phone.
I REALLY like the magnetic phone mount, and do like wireless charging but it a moot point if you have a mounting plate on the back of your phone or case.
I am using amperage and I own two qualcom version 2.0 chargers one from my Nexus 6, and one I bought on amazon. The OEM Nexus 6 draws about 1.6amps on charge, and the Anker 2.0 draws under 300 mAH. The computer 3.0 USB port from a desktop draws 370mAH to charge the phone.
I will probably invest in a true oem qualcom 3.0 charger.
Pretty cheap of Shomi to not include a 3.0 charger

I'm revising my previous post, it seems that the provided charger may indeed be a QC 3.0.
I've been reading that if you use USB-c to USB-c cable instead of the provided USB-a to USB-c cable, you actually get charge rate.
I've also been reading up on the QC 3.0 vs 2.0. Both will max out at 18watts. But 3.0 has a variable voltage whereas 2.0 is fixed at 5V, 9V and 12V. You can see that in the below link, there's a nice table of Watts for each QC.
http://www.androidauthority.com/quick-charge-3-0-explained-643053/
However with USB-C to USB-C, it can charge at full 29Watts. That's a huge difference.
you can see that in the description provided by Anker here
https://www.amazon.com/Anker-Type-C-Delivery-Charger-PowerPort/dp/B01D8C6ULO
You can also see here in this device
https://www.amazon.com/Lumsing-Charge-Charger-Foldable-Macbook/dp/B01I1OIO4A
it says 48W of power, and allocates 19W for QC 3.0 which means the other Type-C port is allocated for 29Watts.
So I think I'm going to be looking for something with a direct USB-C port as a charger.
Certainly, this may be all for not if the Xiaomi Mi Mix is limited to 18W of input anyways.
I have the Anker USB-C to USB-C charger, my initial testing indicate that the original charger (China Plug) and my Samsung Galaxy S6 Edge charger (UK Plug) are capable of doing 23.8 Watts max, i tried to monitor the difference and what I noticed is the Mi Mix original charger seems to be adjusting the charging power more often (not really sure why and whether it's good). My Anker USB-C to USB-C went up to 28.9 Watts Max. All chargers seems to scale down their charging rate after battery reach 80%+ so I think the best way to test is to empty the better and start from 0%. I doubt I will be doing that test though as it's quite hard to empty battery on Mix and I am pretty happy with my Anker charger so don't think I will be using Stock one or my Samsung one.
Unless I go on holiday with multiple devices that still use old USB port, Anker USB-C to USB-C is my go to charger.
So I think what you confirmed was that the mix can take power at 29 watts.
That's good to know.
Just received this wireless charging receiver today that claims to do fast charge
https://www.amazon.com/gp/product/B01LX0Y5CS/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
it does charge much faster, almost double of the one i posted originally in this thread. i'm getting a charge on it around 950ma which isn't too bad for wireless i don't think.
Is there an app I can use to see if this phone is quick charging ? I have a Google pixel charger USB c to USB c. Trying that out now .I can't really judge because this phone is at least 1000 mAh bigger than what I'm used to lol.

Magnetic charging tip

Hello everybody and happy new year!
My original super fast charger which came with the phone won't magnetically charge my note 20 ultra
with the charging cable which I used with my Samsung note 8. I already ordered new pd 60w quality cables+new pd magnetic adapters.
Since I did not find any information -Do I have to buy new magnetic tips (which are stuck in the phone) or can I use the same tip which I used with my note 8? Are there any differences between tips?
Thanks for your help.
Eran
P.S - I am using my Samsung note 8 charger with the magnetic cable adapter in the mean time. The only problem is the slower charge....
If the previous setup didn't work for the new phone, you'll need the new tips too, most likely.
However, especially at the 25W fast charging speeds of the phone, I'd recommend you steer far, far away from magnetic chargers. Sure, it sounds like a nice idea, reducing the stress on the USB port, easy tear-away charging, and so on, but since most of these chargers are incredibly low quality, with bad contacts, you can expect a lot of loss, which manifests in the shape of heat. I remember with my Note8 I did the same, and the phone would get uncomfortably hot - and that was only 15W. Imagine what 25W would do.
The only magnetic chargers I trust are the ones specifically made and tested for the device - e.g. Apple's (old) MagSafe on MacBooks. And even those had heating issues.

The super faster charger doesnt play nice with alot devices iv come to find. I had an issue using a 2 in 1 charger/ aux adapter. The charger kept connecting and disconnecting. It seems to be some thing special to that brick specifically. Especially since its a 45w charger and I tried a ravpower 45w charger and it did not super fast charge my phone. Soo, yea. Super fast charging will only happen by way of samsungs official charger... which doesnt like alot other add-on devices (dongles, magnetic tips, ect).

Looking for a wireless car charger

Hello! I'm looking for a wireless car charger for my Samsung Galaxy Note 20 ultra. My Baseus charger (on the screenshot) broke after only a year of usage.
It has 10w output and so when the navigation is on it only helps keep the charge.
Sometimes Xiaomi 20w car charger is recommended but according to reviews it still chargers Note 20 Ultra with 10 watts, 20w is only for Xiaomi charging protocols.
Can you advise me a charger that is compatible with and can charge the device with more than 10w?
Just look in Amazon, there's a lot of them that offer different watts for charging, not expensive either unless you go with name brand
I am looking for one as well. I have two scosche magicmount chargers that are fast charge. The 9v 1.67A or roughly 20 watts, but these will only charge the new note 20 ultra at 10w. From what I can tell they start off fast charging then the phone stops them and only allows the 10w. I took one of these apart along with a Samsung branded fast charger, the biggest difference I saw right away was the samsung charger had dual coils. So I think that may be the difference the phone recognizes because the voltage and amperage are the same.
I'd like to find one that has the same or similar magnetic mounting system. Its mostly a matter of convenience but also I have used clap ones before, not all were wireless chargers but the manual one often broke on me and the one automatic one I have has a touch button on the side that is very sensitive, so it often releases when I don't mean for it too.
@adj998 Yes there are plenty on Amazon, but unfortunately it seems Samsung has deemed this single coil wireless chargers as inadequate and disables fast charging on them.

Its mostly a matter of convenience but also I have used clap ones before, not all were wireless chargers but the manual one often broke on me and the one automatic one I have has a touch button on the side that is very sensitive, so it often releases when I don't mean for it too.
@adj998 Yes there are plenty on Amazon, but unfortunately it seems Samsung has deemed this single coil wireless chargers as inadequate and disables fast charging on them.

This is the best one I've had, been working for a year and charges like a samsung wireless charger.

How has this Xiaomi charger fared? And how fast does it charge the N20 Ultra? The one I have doesn't charge the N20, just keeps it at a constant level but the same charger does charge an S7 and a Note 9 much faster (so probably coming up against the Sammie 'lets annoy customers by making them buy only Sammie wireless chargers' issue!). I have tried moving the phone up/down a bit to see if that's the issue but no luck.
So, looking to get something that charges faster and will get this one if it does so. Anyone else have the Xiaomi charger and is happy with it?
I am still happy with it, it charges my s23 ultra fast, the screen says fast wireless charging so, it is still good.
