I've replaced my old lead batteries with this one for my astronomy setup. It's several kg / pounds lighter and last longer. It's even more practical because I can easily charge it over USB-C (tested up to 60W). Great product!
I never received my powerhouse. I reached out to support and they say they cant do anything because it’s a shipping problem
I was very happy to follow up with you again and am pleased that we can still do something to accommodate you.
