My husband and I recently just returned from vacation. Through my supplier, I had the pleasure of using the Liberator 10 LOX Reservoir made by CAIRE. It's a neat little tank, has a built-in flow meter, a LED display, oxygen outlet, and comes in either top or side fill. The tank holds 10 liters of liquid and weighs only 53 lbs filled. I can lift the reservoir myself, but it's my husband that likes the ease of lifting it in and out of our Tundra. Currently I am on 2 LPM 24/7 and this reservoir lasted me 5-1/2 days. It's very quiet filling and my portable got between 9 - 10 hours.
