For Field Day I have the Anker Solix C300 Portable Power Station with a 100 Watt Solar Panel.

The Anker Solix C300 puts out 10A at 13.4vdc and 120vac at 300 watts. I think it will be adequate for the renewable power required to make 5 contacts for the 5 extra ARRL points using a suitable 100w mobile HF rig.
