To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
I use this for my retro game consoles. I have so many of them and I don't need power to all of them at the same time I wanted to something that I could just switch on and use, and this seems to do the job just fine. I've seen in other reviews that the USB did work for some people. I haven't had that issue, but I'm just charging Bluetooth controllers with it. Overall I'm happy with my purchase and I've had it for several months and not experienced and issue.
