Review on ONSMART USB Surge Protector Power Strip with 4 Outlets and 4 USB Ports, 3.4A Total Output - 600J Surge Protector Power Bar, 6 ft UL Listed Cord, Wall Mountable - White by Eric Salem

First I bought this extension for USB ports. I was so disappointed when none of them worked properly to charge my smartphone. I have a Samsung S10e. I tried several charging cables (official Samsung cables and cables from other manufacturers). I tested the cables on other USB ports to make sure they charge my phone quickly and work well. So it wasn't a problem with the cables or my phone. I got the same slow charging message for every USB port on this power strip. Ridiculously slow, for example, almost 10 hours to charge the verses of a 43-minute charge (see pictures). If I plug a wall charger into a power strip and charge my phone that way, fast charging works, but it defeats my purpose of purchase. this power supply. I wanted working USB ports for my family's phones without being bulky and room to connect other electronics.
