I bought an extra battery that says 2500 =5 hours of use but in the flyers inside it says 2500 will only give you 1 & 1/2 hours only .so it's kind of misleading for a customer .

My dad accidentally purchase a pulse oxygen concentrator. Since, he really needs a portable oxygen when traveling. Would there be a possibility to change the item into a continous flow oxygen mode. The item has just arrived yesterday July 1. Thank you!
