First, because they are meant to be portable, they are typically lightweight and will weigh less than 20 pounds. They will also have controls so you can determine just how much oxygen you are getting through the device.
How portable oxygen systems work
A portable oxygen system works similarly to the large at home models. They can take and purify air from the atmosphere, remove the nitrogen, and then deliver that oxygen to the patient through a nasal cannula. These devices will use a battery for power in most cases, but they tend to have the ability to connect to an AC or DC power source as well. Some models actually require oxygen canisters for refills. Keep in mind that this variety will usually be a bit heavier, as you have to account for the weight of the canister as well.
