Where to buy a power converter on SXM?

We’re staying in Grand Case and need to purchase a power converter so my daughter can use her electronic game that is only 110. The converter provided in our rental isn't working. Anyone know where on the island we might be able to purchase a converter?

I am in Grand Case and can let you borrow mine, I brought thinking we would need it, but doesn't seem like we will need it this trip

Try ACE in Cole Bay.

Or try Equip in Hope Estates.
