Portable oxygen concentrator
Hello, I'm looking for a good Portable oxygen concentrator, tell me where can I order such a device?
Hello everybody. You probably know that oxygen concentrators are a reality for many people suffering from countless ailments. If I am looking for a portable oxygen concentrator, I am looking for the ones that will provide maximum benefit and the main criterion for this is battery life. I read in Inogen's reviews here https://inogen.pissedconsumer.com/customer-service.html that their new hubs go beyond the already impressive 10 hours offered in previous models, extending battery life to 13 hours when using dual batteries.
