Used once for a camping trip and kept our Bluetti battery charge to 100% constantly. Not an exact measurement but was getting 140w charge in June, occasionally dipped to ~100w but very dependent on the sun (obviously). We ran a 40w fridge from our battery and charged via this panel and we had plenty of charge for the fridge and all our devices/lights. The foldable suitcase design is lightweight small and easy to stow when not in use. Only selling as it will be gathering dust for the next year or so before our next camping trip. we paid £190 for it and only used once.
