I've read many tales where the protagonist is allowed a baggage allotment by the aliens. Volume and weight vary.
But none of the tales that I can remember included a dozen cordless and rechargeable via a small solar panel Hitachi Magic Wands.
Ah… imagine the gifts that could be bestowed. Instant friends with the powers behind the throne kinda deal.
Yeah, yeah, they'd eventually wear out, but before that? Ooo La-La!
