APC TeleAdapt Inflight 90W DC/AC Kompaktwechselrichter 12 V DC auf 120 V AC TANOTEAC90A
The mains connector is a 2/3 pin US NEMA - see photo. Typically it could be used for powering or charging a laptop in a car. Typically they run from 100v AC to 240v AC and as long as it takes less than 90w then it should be fine.
