Hi to all,
Can we charge S21U with 40W chargers? They are a lot chargers like Huawei, Xiaomi and etc... with 40W and more.
I believe the answer is yes - or at least probably. Most of those newer chargers are "Smart" in that they only provide the volts and amps that are needed by the device being charged. I may be wrong about that, but I don't think so - I don't think you have anything to worry about.

Pretty sure you can, I use a 45 watt "smart" charger on my NOTE 20 Ultra without any issue.
You can use any charger that supports PD (power delivery), AFC or QC2.0
Any 45 watt USBC charger out there is going to be PD standard so you'll be fine.
The downside is, it'll still only charge at 25 watts.
I am charging my s21U with an 40w charger, works without problem. not using 40 watts of course, but its working.
The phone, all phones in fact, will ONLY charge at it's highest speed the phone allows itself to receive, the charger doesn't matter, it can be lower or higher than what the device is recommended for. A lower power charger will just take longer to charge the phone, a higher power charger will just not charge at it's full power if the phone won't accept the full power from the charger.
I've been using the 90w charger from my HP Spectre X360 my S20 Ultra since I got it without a single issue, I still get about 2 days of use per charge on that thing, and now I've been using the same laptop charger on the S21 Ultra and it works just fine.
The phone fast charges normally, doesn't get super hot, works just fine, and I only need to keep laptop chargers around the house, it's great haha
I have a 45W USB-C PD port as part of an Anker PowerPort and also the 18W charger that came with my Pixel 5. Would I notice much of an improvement in charging speed or integrity/longevity of the battery by purchasing Samsung's 25W charger?

That's the charger I've been using w/ S21Ultra (25W from N10+) and I figured out I won't be needing anything bigger then that. Thanks to Samsung 'super fast charging' the 5Ah battery on s21U charges faster then 3.8mA Pixel 4a5G battery(with the same charger). +/- 1 hour and done!
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!
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.

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.
I bought a HEYMIX 45W GaN PD Wall Charger, 30W USB C Fast Charger, Max48W Dual-Port Quick Charger AU Plug, Compatible with Galaxy S21/S20/10, iPhone 13/12 Pro Ma (thats a mouthful) for this tablet but i have an annoying issue since I started using it. I have constant popups showing the charge %
I have tried a couple different cords. I thought it might have been Gauge Battery Widget so I installed Battery Reborn and no difference
Is there anyone else with this issue that can help please.
Many thanks in advance
Same thing used to happen to me on my Tab S7+ when connecting to a non Samsung charger. Try the original charger or a high wattage charger. On my Tab S8 Ultra I have no issues when charging with a 65watt Oneplus charger.

To clarify - there is no "original charger". Samsung doesn't include chargers anymore. I suppose you could mean one that Samsung sells that's aimed at using with this tablet, but wow they're expensive and limited (one USB-C port) for what they are. Looks like Samsung is out of stock of both colors - no idea if you can find them elsewhere.
I haven't been actively using my Tab S8 Ultra enough at the same time as charging it so I don't know if I would experience the same thing. I do have the recent Anker 3-port 100-watt charger for when I have to charge fast (at 45-watts), but I haven't had a need to do that yet.
Thanks for that, the company I bought my charger from sent out a 65w charger and it works great
Which charger (with cable) will charge the S23 (not + or Ultra) the fastest?
Use the OEM Samsung cable/brick.
There is no OEM one, no? As in the box. btw it supports max 25W so the "Samsung 25W PD Adapter"

Samsung went chintzy with all the "extras" like a brick/cable in the box. The N10+ came with them.
So... yeah buy the OEM Samsung 25W charging set. It's actually a high quality pair. My original set is still tight and running good after almost 4 years and thousands of charges.
Don't roll up the cable once unpacked to prolong its lifespan.
Thank you for your responses!
I ended up giving these a go, and they charge my S23 from 1% to 100% in less than 1h and 15 minutes (I even a few things on the phone while charging).

I use the ''Ambrane 45W Fast Charger'' with cable that came along the phone and have been very satisfied (using device & charger since 24 Feb). Charges the phone from 0-100 in about 40 mins (0-85 in around 30mins). The phone has a "superfast charging" feature very few know about and correct cable/pd bricks do this trick.
What is Samsung Super Fast Charging?
Samsung's Super Fast Charging offers up to 45W of charging power, but you can't expect the same performance on every device.

Not sure why it says that, maybe 25W max with the normal fast adapters and not the adaptive/power delivery adapters. I get a superfast charging text/ teal colored ring when I switch on the toggle for fast charging and green ring/charging text when it's off.

Checked on Ampere it shows:
4400 mA max output with the superfast charging
1850 mA max output otherwise
Hopefully, someone with a better knowledge might be able to help us out!
