Using Propane for Ecoflow generator
For those using propane on an Ecoflow generator with portable tanks, there are a few things to be aware of.
The relatively new standard (around year 2000) of portable propane tanks under 100 LBS have what's called a Overfill Protection Device Valve (OPD) which handle looks like a 3 pointed star.
The obsolete type (POL) looks like a 5 pointed star or round shaped handle, if you have one of these, please exchange for a new one. Perhaps someone has an old style lying around.
About exchange places, they usually do not fill 20LB "barbeque" tanks fully, but they are a good place to exchange an old tank, otherwise its best to take the tank to a place that actually refills the tank to get a full tank.
Lastly, propane tanks need to be recertified at the 12 year mark. The manufacture date is stamped in the top collar of the tank. Again an exchange place is good for this.
