According to an article on pcmag dot com, this surge protector offers 1,710 joules of protection. Google search for “HS300 joules pcmag” and it should be the first result. Hope this helps, as I had the same question but couldn’t find a good answer.

Q: Does the energy monitoring monitor each port individually or the whole power strip?

The HS300's Energy Monitoring feature provides the ability to monitor energy usage for each individual port. Regards, TP-Link Support

Q: If you lose power when it comes back on line, what happens if the internet is down? Do the outlets return their prevous state or stay off?

Oh.. so you mean power is back while internet is not? Yes, it will return to previous state but you can't control it until the wifi is back.
