I would not suggest using one of these and then putting on a 30A to 15A adapter and plugging an extension cord into that to operate your various kitchen things. In terms of voltage and so forth it's a fine setup; the concern is that the overcurrent protection would be 50A for your 15A circuit, and it would be pretty easy to overload the 15A extension cord dangerously, ...
Reasonable concern, but the simple solution is to ALWAYS use a power strip with a builtin 15A breaker at each campsite ! Less than $10 each on Amazon.
