This air pump is scrap. I have been doing water sports as my main hobby for 28 years. I've seen a lot of equipment over the years as I tend to buy used equipment to save money. In the photo, the air pump is on a windowsill with a line going to each of these 5 gallon betta units. Charged all night via USB, then powered on for about an hour. The low battery indicator not only lights up, but also noticeably slows down. The solar panel is actually connected. To be honest I'm not even asking for a refund or replacement. It's not worth the headache. The solar panel is cool though and my boys play around with STEM toys and they would love the panel. I'm an outdoorsy mom so at least this will keep my minnows alive. I'm sorry but this product compares very poorly to other things I've bought from Revain recently. The only woman to claim her pool aerates half of a 1,000-gallon pond fell off a rocking chair. Just not true.
