Because I see many complaints from Samsung users about charging speed, it is worth noting that this charger is 9w, which means it is wireless fast charge 1.0. Samsung has now released Fast Charge 2.0, which is 10w+ (up to 15w on its new flagship devices).
Even the Note 9 charged wirelessly at 10w, so you are getting almost the maximum supported by your device. Starting from the S10, Fast Charge 2.0 is available, so you will need a Samsung fast charge 2.0 charger (the 1.0 charger is also compatible, but only up to 9w). There are Samsung chargers available from 10w up to 15w, but they are expensive. For example, on a Samsung S20+ with a 15w Samsung wireless charger, it takes almost 2 hours to charge, assuming the room temperature is relatively low (in summer, with a room temperature of 30 degrees, it takes longer because it increases the temperature and reduces the voltage to a maximum of 10w). So, this 9w charger will take over 3 hours to charge the 4500mAh battery of the S20+ from 0 to 100%.
Another thing worth noting is that in order to work properly at the maximum 9w, you will need either the Adaptive fast chargers (15w) that Samsung had from the S7 onwards, or a Quick Charge 3.0 USB-A charger with the corresponding USB-A to type-c cable. If the adapter has a type-c port (meaning the cable is type-c on both ends) like the 25w Super Fast Charger that the S20 and Note 20 have, then it will not work properly because the new type-c adapters follow different charging standards (Power Delivery 3.0).
The Samsung charger in question is no longer worth 16 euros. You can find cheaper 10w chargers. Mine broke over time and I threw it away.

It was purchased to be used with the Samsung Galaxy S20 Plus.

Inside the package, the wireless charger includes only the charging pad and an instruction manual.

It does not include an adapter for the socket or a cable. So you have to use your mobile adapter.

The strange thing is that with the 25-watt adapter of the S20 Plus, it does not do fast wireless charging, even though it is enabled through the mobile settings.

When I connect it to an 18-watt adapter, it does fast wireless charging. I assume that because it was intended for S10 Note 10 mobiles, the high wattage of the charger is not compatible with the S20 Plus.

The charging pad is USB type-C. It has an LED on the front that lights up in three colors: red, orange, and green. When the S20 is fully charged, the light is green, and during charging, it is red.

It also has a non-slip surface on the top and bottom.

Be careful not to step on it because I bought it with the intention of charging everything... mobile... Galaxy Buds Live... and Galaxy Watch. But it cannot charge the watches.

It successfully charges the Galaxy Buds Live and the mobile.

It cannot charge the watches, neither the Galaxy Watch, nor the Gear S3, nor the Galaxy Watch Active. This happens because the capacitor inside the wireless charger is larger compared to the capacitor in the watch's wireless charger, so the current cannot pass through. So forget about charging the watches.

With fast wireless charging disabled, it takes about three and a half hours to charge my mobile (4,500mAh battery).

With fast wireless charging enabled, it takes about 2 hours and 20 minutes. All of this depends on the temperature and the room, of course, because if the mobile's temperature rises, I have noticed that it stops charging until the temperature drops, thus protecting the battery.

When it is charging and you have it next to your nightstand and it is nighttime with absolute silence, it can be heard slightly, and it may bother some people.

Certainly, for this price, you don't get anything better in a wireless charger or something more powerful. The fact that it is the official Samsung one is definitely a positive. And it is certainly more battery-friendly.

Very nice. I bought it for my Galaxy S10+. Although Samsung recommends the dual pad for the S10+ as it charges very fast at 15W, this one costs around 70€ and I'd rather spend that money on souvlaki, not a charger. I can wait a little longer for it to charge, it's not the end of the world. It's very beautiful, very good quality construction, and discreet for use in the office. Both the S10+ and the S8+ charge quickly (as mentioned by the phone), the charging is a bit slower than the cable of course, but the practicality makes up for it. It has a very useful LED that remains red while charging and turns green once the charging is complete, ideal if the phone doesn't have notification LEDs or if you want to see it from a distance.

Be careful with the charger, with an Anker one that I was using and charged the phone quickly with the cable, it couldn't provide fast charging to the pad. I used the S10+'s original charger and it worked perfectly. The cable also needs either the original one or one that supports 3A (I used a BlitzWolf BW-TC5, perfect).

It is fast but the mobile (Note 8) with a simple cable and fast charger takes almost 2 hours for full charging, while with this +45 minutes approximately! I bought it for 17€ and I consider it okay, but for 25+ that it costs in official stores, I think it should come with a cable and adapter, otherwise it is expensive just on its own. However, it is elegant, giving the feeling of an expensive gadget, and it can easily fit into a professional office or a more refined space without giving off the tackiness that some other chargers of the same type do! It has a light with 3 colors: red, orange, and blue, depending on the battery level of the mobile, and it charges normally with any Samsung case or aftermarket case that I tried on the mobile! I could live without it, but it's fun to have!

UPDATE 12/12/2019
I charged it with a genuine Samsung silicone case and the mobile heated up significantly.. however, the charging was done normally and it worked flawlessly.. I don't consider it right though for the device to heat up so much regardless of whether this works normally!
