Review on Upgrade Your Camping Gear With Aupoko Propane Refill Hose – High Pressure, 36 Inch Extension Hose, Tank Adapter And On-Off Control Valve Included! by Tina Coleman

Works great but you have to plan ahead to refill the 1lb tanks. The 20lb tank needs to be in the sun for a few hours or in a warm garage. The 1lb tanks need to be placed in the freezer for 2 hours. If you do this with the 20lb tank upside down you can fill the 1lb tanks in less than 5 min, otherwise it may take forever or not work at all. Also worth mentioning is the air should be purged out of the line before hooking up. It's well worth it since the cost of refill is under a $1 and a new 1lb tank is $5.
