Power cord/circuit analyzer waterproof combo?

I'm setting up my van for my Mom to use. I'd like a power cord that has the handle to help older hands manage the plug. However, I also want a surge protector/circuit analyzer.

My problem is there doesn't seem to be a surge protector/circuit analyzer that has the plastic cover that will fit a cord with a handle on the plug.

Can anyone recommend a brand or point me in the right direction?

Thanks in advance guys.
