Jim:
One-pound propane cylinders are easily refillable if you use a couple of tricks. A filling adapter is available for under $20 from [Harbor Freight and other merchants.
You need a full 20# cylinder as the "donor". Place it in a warm place or in the sun for a couple of hours. Chill the empty one-pound cylinders in your freezer.
Join the cylinders. using the filling adapter. The filling procedure is that you invert both of the joined cylinders and open cylinder valve. Refills take about one minute each. Regards, – Rob S.
