In theory, yes, I use it exclusively with a Sherpa 100ac. Personally, the power would be too little for me to carry out the necessary conversion (inverter, etc.). I would clearly prefer the solution from balkonsolar.ch.

As far as I know, there is no such thing. For your purposes, I use a panel from Xtorm and am very satisfied with it. Xtorm SolarBooster 21W+Rugged Powbank

According to my research, the Yeti 500x has the following DC input: 1 x 8mm port:13 V - 22 V up to 10A (120 W max) If I have misunderstood your question, our product experts from customer service can certainly help you: https://helpcenter.galaxus.ch/hc/de/requests/new

Hello I have not measured the cable but for me the length is enough. Without extension I would estimate that it is 1.5 metres long. I would still recommend an extension cable for flexibility.

Yes, it is compatible with goal zero 200. and I bought together. And I got cables also. But I don’t know when you buy alone ....

Hi I just tried this today with our little Nomad 13...worked! The Boulder50 with MPPT controller managed 34Watts when I connected the little old Nomad13 with the Boulder50 it was 41Watts. lg Anne

Yes, rain is no problem. I wouldn't take it diving ;-)

Attention, the Yeti 150 charging input has a maximum charging power of 60 watts. https://www.goalzero.com/shop/power-stations/goal-zero-yeti-150-portable-power-station/#product-detail-specs-2 or https://www.goalzero.com/media/files/yeti-150-user-guide-3-de33.pdf You can couple two Boulder 50s together. The necessary cables are available - see https://www.goalzero.com/media/files/boulder-50-user-guide-26-201d.pdf But in the case of two coupled Boulder 50s, the specification of the Yeti 150 is exceeded. Even if the coupled solar panels do not effectively reach the summary power of 100 watts, one can expect 70 watts in good conditions, which would be too much.

Yes, if the sun is obscured by a cloud, and then the cloud goes away, the panel restarts. I did the test by manually orienting the panel until the charging stopped, then I reoriented it to face the sun, and the charging resumed. I have done this test several times with success. I hope this answers your question. Hervé
