Portable oxygen concentrator

I am a 43 year old single mum of 5. I have suffered from neuro and pulmanory sarcoidosis for the last 6 years and have been on oxygen around 3 years.
I’m generally a positive optimistic person but the one thing that can get me down, is the lack of freedom being on oxygen can cause.
I have an oxygen
concentrator at home and use liquid oxygen when out but this lasts only about 4 hrs so I’m constantly
clock watching.
There is a solution, a portable oxygen concentrator which runs on batteries which would mean I could go out for full days, and also go away for the odd night, without weeks of planning.
Unfortuanly the portable concentrator are not available on the nhs so although I hate to, and have mulled it over for a long time, I’ve turned to go fund me, to help.
Thank you so much in advance for any help you can give,
with love Carol x
