Review on Rosonway Aluminum 7 Ports USB 3.0 Data Hub with Power Adapter - USB Hub 3.0 Expander for PC and Laptop (RSH-A37S) by Rick Kreutzer

I've only been using this for 20 minutes and already regret buying it. In winter I use plant lights and they all use a USB box like a phone. These lamps are small and do not consume much energy. I even checked the volts to make sure it was working. In theory, this should have met my needs. However, I can only connect two of them securely. Three causes the lights to flicker, and when I try to use four, the entire hub overloads and shuts down. So basically I have a 7-port charging hub that can only be used for two items at a time. I could have saved a ton of money just by purchasing individual charging blocks instead of a hub. Don't waste time with this product if you intend to use all slots at once. It will not work.
