Review on PAXCESS 50W Solar Panel Charger for Suaoki Portable Generator / Goal Zero Yeti 100/150/400 Power Station Battery Pack / USB Devices, Foldable Design with 3 USB Ports by Johnny Spencer

I use this brand with my Goal Zero Yeti. Rockpals comes with adapters for other brands of batteries including GZ. It's rated at 50 watts, and I can usually squeeze 30 watts out of it. I can use all 3 USB ports and still have enough power to charge the Yeti inverter. The cable is long enough and durable. If I really need a lot of juice, I have an adapter that connects multiple ports so I can use multiple of these panels at the same time. Grommets are good and strong for hanging.
