I have a Belkin Qi2 25W 3-in-1 Ultra Charge Pro, and I wanted to have another affordable Qi2 25 wireless charger, so I purchased this product. I tried using it with an auxiliary battery that can monitor it, and it outputs more than 25W. However, the disappointing part is that Belkin's fan automatically turns on and off to dissipate heat, but with this product, whether there's a fan or not, I can't hear the fan spinning and heat builds up. It doesn't get extremely hot, but it's warm enough to feel cold compared to Belkin. Still, the cost-performance ratio is excellent. The quality is just cheap plastic material, and the phone wireless charging stand is also made of plastic overall.
