Tanks and cylinders come in different sizes, with different amounts of oxygen, and are made by different manufacturers there is a difference between a cylinder and a tank relating to the state (liquid or gas) and this difference means that there are variations, specially regarding durability, but also in the refilling process.Many times the two terms are used to refer to either of these oxygen containers, but in actual fact one refers to a container that holds it in liquid form and the other to compressed oxygen.
The other important aspect is the portable side of the name. This means that the container is not a stationary structure and therefore can be moved around comfortably. There are also mobile tanks and cylinders and this restricts the size and weight as a user must be able to carry it comfortably. A portable tank or cylinder may be pulled along on a trolley for example, as its weight and size reduces the patients carrying ability - but it is still portable, and an excellent means of supplying oxygen while practicing many activities.
