This solar case is a bit heavy, the price is a bit high but it's The perfect size, it has decent built-ins Stand and the quality of the device is much higher than others I've seen. In hazy skies it showed 168 watts in the late afternoon as soon as I set it up for the first time, so 200 watts should be available at higher altitudes and clear skies. Pointed roughly at the sun, this case pulled out more juice than the 380-watt hard panels on the Victron 100/30's camper roof. The included Victron 75/15 controller is small for 200W, but you can set the temperature protection, charge voltage, max current, etc. in the Victron App. Many other cases come with a cheap PWM controller. nice to see a decent MPPT included in this one.
