Yes, plug in GFCI adapters are readily available these days. Just make sure you get one which does not require a manual reset in the event of a power outage, many of the plug in ones are like that. Check my earlier post where I provide info regarding some of these which are designed for the shop & power tools. I can trip the circuit breaker, reset it, and my receptacle GFCI (a la Snaz) will power up again as well without a reset. I also have a single plug in type adapter which needs to be reset every time I unplug it, so it would also need a manual reset in the event of a power outage. It's a handy little device for plugging in wherever you might need GFCI protection, but I wouldn't use it for any of my tank gear.
