... then BEFORE plugging in check the unloaded source voltage ...
... and if it's anything less than ~ 110 vac you want to think about whether you really do want to plug in and draw from that source, knowing that under load that incoming voltage is going to drop even further, possibly below 105, 104 vac.

Assuming you're satisfied the source voltage is adequate, NOW is the time to plug in. Also not a bad idea to continue monitoring that incoming source voltage with the circuit under load during your stay ... I use a Kill-a-Watt meter conveniently mounted near the galley where it's easy to see at a glance.
