Qi2 chargers

[MPJ81]

Does anyone have any recommendations for a qi2 wireless charger that can fast charge an S25+ with a qi2 case with a watch and buds?

I've seen that Samsung might be releasing such a thing but there's no sign of it for sale anywhere. 

I bought a third party charger that was advertised as qi2 compatible "ultra fast". Whilst it's magnetic, it charges at a snails pace. My ancient Samsung duo charger does a better job without qi2.

The s25 series supports 15w fast wireless charging. You can kinda ignore the whole qi2 thing as the phone needs a case for it to actually qualify. And the speed wont go past 15w anyway. The fastest charger for it right now would be a samsung wireless charger that supports fast wireless charging 2.0.

That's the same as the s22. Nothing really changed other than they gave it a fancy name.

There was rumours it'd do 20w or more but all the specs lists show no change in speed

Samsung is selling Qi2 cases to make them compatible with wireless chargers that are Qi2 so you don't need to ignore it if having magnetic connections will make life easier.  However, to clarify the answer to the question: there is no fast charging wireless.  Qi2 MAY at some point be able to charge faster than 15w but not right now.  The 20w wireless chargers take in 20w but only output 15w.

I purchased and tested the “ESR Qi2 3 in 1 Wireless Charging Station with CryoBoost, [Certified] Phone-Cooling Wireless Charger & 15W Qi2 Charger Stand”, and because of the design, it worked with all of the MagSafe cases I've purchased. Most cases have a raised rim around the camera lens area that prevents the case from making a flat connection the the Qi2 charging area. I hooked it up to my "HyperJuice 245W GaN USB-C Charging Station (for Desktop)" with the USB-C cable that came with the stand. To test the wattage draw, I plugged the USB-C cable from the port on the HyperJuice, into a "Plugable USB C Power Meter Tester", which was than plugged into "ESR Qi2 3 in 1 Wireless Charging Station". When I attached my S25+ or my wife's S25, both of which were in certified MagSafe cases, the phones said they were fast charging, and the meter showed that Qi2 was drawing 20.1W of power.

This stand comes with a Apple Watch module that plugs into the back of the stand, which I won't ever use, but I will plug the cable to my Galaxy 7 Ultra fast charger into the plug where the module was supposed to plug into, saving a port on my HyperJuice.

For the record, ESR also sells a 2-in-1 Qi2 charging stand similar to the 3-in-1 charging stand that doesn't have the 'CryoBoost' cooler on it, and doesn't come with the certified Apple Watch fast charging module. It still has the USB-C port for the module, on the back. I plan to pick one up to test, and if it doesn't get hot during charging, will put it on the night stand, next to the bed. I'll leave the original 3-in-1 stand in the office.

I'm saying, you've been able to get magnetic cases for a long time now. They kinda just stuck a name on it. The charging speed hasn't increased so nothing really changed

The MagSoft cases for the Samsung Galaxy S25 Series phone have just recently come out. Problem some people are having with using Qi2 charging of the Galaxy S25 Series is finding a charger that allows the MagSafe case to lie flat on the charger. When I checked a couple of Qi2 chargers, the bottom camera lens was too close to the Qi2 charging magnets and prevents the case from lying flat on the charger. This results in only being able to charge at 7.5W.

Yes, if you want to 'super charge' your Galaxy S25, you would connect it directly to a 45W or bigger charger, but lot of people, like me, are looking for something that can 'fast' charge our phones, earbuds, and smartwatches at the same time.

Samsungs older fast wirerless charging 2.0 tech has 15w working fine. It just took a few seconds to align the device correctly. Third party magsafe cases have existed for older phones too. I'm not denouncing qi2 or anything. Its just the speed and magnets have already existed and been available. Even my s22 charged at 15w wireless

Did the 20w remain constant during a long time? What cases did you use? How thick were they?

The charge fluctuated between 20W & 21W all through the charge.

I also purchased the "Anker MagGo iPhone 16 MagSafe-Compatible Wireless Charger Stand, 15W Fast Magnetic Wireless Charging Station, Qi2 Certified 360° Charger" that only does Qi2 charging. It's just a Qi2 charger, doesn't have a cooling fan like the ESR, and the magnets don't feel as strong as the ESR charger. It takes about between 30-45 seconds to kick into Qi2 charging, and fluctuates in the 20W range all through the charge.

It's on the night stand on my wife's side of the bed so she can throw her Galaxy S25 on it when she goes to bed.

Thanks. I asked about the cases because that seems to be what's preventing me to reach 15W with my s25 ultra. I have as ESR qi2 car charger, without cooling fan. Without case, after finding the sweet spot where alignment is just right I also get 20W to 21 W, measured with a usb meter placed between the power adapter and the ESR. However, with the 2  cases I tried so far I only get 12W. I'm now using the spigen tough armor which is around 3mm thick. The previous case was also thick. Which case are you using?
