The 8 is great!

I couldn't decide if I should just order another 4 Hr or go for the 8. I decided on 8 hour when I'm gone for the day, I did get the backpack since it's easier to carry because it is heavier & can easily carry my purse too! It turns out to be far more convenient than I thought.
battery life
Jeff Myers✓ Verified Purchase•August 21, 2023
Would be helpful if they had a chart that showed how long the battery will last at different settings. Now they say the battery runs for 9 hours. I set my machine at 3 and the battery ran for 6+ hours. The 9 hour claim must be for setting 1.
Works perfectly

Power to go

One battery wasn't enough. So, we doubled our power
More freedom!
Staci Christensen✓ Verified Purchase•June 22, 2023
I have had this machine for year or so and have been happy with all but the battery. The single battery just doesn't give me that much time to do what I need to at 3 lpm. I saw the double here and hesitated on the cost. I'm glad I got it! Now I use the single as a back up, no more anxiety about battery usage. I don't know why I waited. Definitely worth it.
