Review on 🔌 j5create 7-Port USB 3.0 Data Hub with Extended Cable & Power Adapter for Mac, Windows, Laptop, Surface, PC - JUH377 by John Rodriguez

I put 2 chains in series and they work fine since I bought them. I can tell you this can come in handy for anyone using a powered USB hub: when overloaded with power-hungry accessories and losing its own power supply, the ports with unpowered accessories will burn out. This is what happens on your computer when you try to use a powered external drive without it plugged in, or the same with a non-powered USB port. A power outage in your home or a surge can spell the death knell for any powered USB hub. Now I have whole house surge protection and a UPS system with an independent circuit breaker, so maybe I'm luckier than most. But I learned the hard way after many fried knots.
