Foil packet works fine.

Yes, easily. The foil packet method is the standard workaround and honestly works as well as most smoker boxes.

Soak chips in water for 30 minutes if you have time (delays burning, gives more smoke). Wrap a generous handful in heavy-duty foil, poke several holes in the top with a fork, and set the packet directly on a burner grate over the flames. Crank that burner to high until you see smoke, then turn it down to low-medium to keep thin blue smoke going. Put your food on the other side of the grill, lid closed.

Only need to refill every 45-60 minutes. Dried-out chips burn too fast and taste bitter, so keep spares soaking. Don’t go overboard with chips—more isn’t more, it’s acrid.

This is not where you need to buy another gadget.
