Do any of you use a propane tank refill adapter like the picture below? I connect this adapter to my 25 lb. BBQ tank and use it refill small 1 lb. propane tanks (like the camping tanks or propane torch). Or at least I am trying to. It works but the 1 lb. tank only feels about 1/2 full as compared to how one feels when purchased new. The adapter I use says to leave them connected for 1 minute and you can hear the small tank being filled for about the first 45 seconds. The sound dies off so it seems to be done filling a little before the 1 minute mark. I haven't tried filling it longer but wondered if there is a secret to doing this to make it fill more?
