Dear David, Thank you for your detailed 4-star review of our 2L Smallest Portable Oxygen Concentrator. We truly appreciate you taking the time to share that it has been a great companion for your gym sessions and walks. Regarding the battery life, we appreciate you bringing this up. The standard battery runtime for this model is approximately 4 hours. It's important to note that this unit is designed to deliver oxygen at a fixed flow rate of 2 liters per minute (LPM) in Continuous Flow mode. Therefore, the primary factors affecting the battery duration are the ambient temperature​ and the total duration of use. During an extended activity like golf, the battery may be depleted before completing a full round. Your idea to use a power bank is an excellent solution! Yes, our concentrator is compatible with external power banks to extend its runtime significantly. For optimal performance and safety, please refer to the user manual for the recommended specifications for compatible power banks. We have also carefully noted your feedback concerning the strap padding for enhanced comfort. This valuable suggestion has been forwarded to our product development team for consideration in future design improvements. Your satisfaction is our top priority. If you have any further questions or need assistance, please do not hesitate to contact our support team directly at [email protected]. Thank you again for your valuable input and for choosing our product. Best regards, The Customer Support Team HealthBeautyMachine
