Subject: Noisy & short battery life
Most importantly, it does the job it’s supposed to , delivering oxygen.
It also has a very short battery life, ~ 2 hours. So, I need the O2 when above 5000 feet and take a tourist train ride to ~10,000 feet, and the battery runs out while I’m still up there.
The other issue is it has a fairly high humm, punctuated with a pounding sound every 5 seconds. When sleeping at 5000 feet, I needed it to sleep, and no one in the room had a comfortable sleep
Thank you for your response! I am so sorry this did not work out for you. One thing I recommend is to fully charge the battery before use AND to use the pulse dosing to help save the battery if possible.
