Review on 65W GaN USB C PD 3.0 QC 3.0 Charger - Powerful Surface Pro Mini Travel Charger for Surface Devices by Joseph Morris

Please read this before you decide not to buy this product. Understanding electricity is important. It has the power needed to quickly charge my Galaxy S21 and my Surface Pro 7. The pointer doesn't lag when I touch the keyboard. Although the charger hums. Sounds like a transformer if you've ever heard it because this device is a transformer. But you must be careful to notice it. By the way, I understand transformers and electricity and I have nothing to worry about. It has to do with how it's designed, whether it's very noticeable or not. This noise is generated by magnetostriction and is due to the way current flows through the coils of this device. You can't beat the price and you have one small device for your phone and Surface or whatever you want to use to charge it, all in one. The only downside is that it requires a USB port. So if you're trying to connect another device besides the Surface, you'll obviously have to buy another charging cable, but it costs money.
