I spent a couple of months in Africa while those around me struggled with inconsistent power supplies, I continued to work using the Nomad 50 coupled with the Sherpa 100 AC. when the power would go down my phone, computer and internet puck kept on going and I didn’t have damaged equipment due to due to power surges.
I used this for 9 days in May in a range of clear sky, cloudy, and overcast days charging a Yetti 150 and powering a Dometic CRF75. Chained with a Nomad 28, I had more than enough power! High quality, stows nicely, well protected when folded. It was rained on 5 of 9 days without a problem. It got very dusty but cleaned up nicely at home. I really like GZ products - they are more expensive but are great quality.
