I bought this product because I wanted a wireless charger that I could put on my bedside table and easily charge my S21 FE, Galaxy Watch 5, Galaxy Buds Live and Galaxy Buds 2. It is also very easy for all these devices: my Galaxy Watch 5 falls nicely into place thanks to the magnets, just like the charger itself. It does charge less quickly than with the regular charger (even though it is the only device on the Trio charger). My S21 FE and the 2 pairs of wireless earphones charge on this charger without any problems. The S21 FE does only charge at 9 watts wirelessly while it can handle 15 watts, but this is in the name of the product and since I charge it overnight with this charger this is not a problem for me. You insert the USB-C to USB-C cable in the middle of the back of the wireless charger (which is not illogical). Personally I would have preferred this on the left or right side but it all depends on your own preference. The cooling fan makes a very small noise. You should know this in case it ends up on your bedside table (like me), but you don't hear it when you're turned away from it and very quiet when you're turned towards it. The 3 charging lights are also constantly on (when there are 3 devices on them), but again this is just a matter of habit. For me, this fan and the lights are no problem.
I think the price, which is certainly not low, is justified. The charger can charge 3 different devices simultaneously at a decent speed without any problems. This charger also comes with the Samsung 25-watt Power Adapter, which costs more than €25 separately.
I would like to point out that the information on Samsung's own website is wrong. The list of supported smartwatches only consists of the Galaxy Watch Active, Galaxy Watch 2 and Galaxy Watch 3. The list of supported phones also ended with the Note 20 series. I contacted Samsung Support about this because I wanted to be sure before making the purchase. However, the agent told me that this was not an error and that my Galaxy Watch 5 and S21 FE would not be supported. I was in doubt about this, so I also posted my question on Reddit: here I got answers from users who used this Trio Charger with Galaxy Watch 4, Galaxy Watch 5 (Pro), S22, .... So it is clearly possible. It's a pity that Samsung's site itself isn't up-to-date, and certainly stupid that their customer service isn't either.
This is stated correctly in the description on the CoolBlue site.
CoolBlue also did an excellent job: I ordered this product around 10 pm and they delivered it to me perfectly the next day (Saturday) with Bpost.
