Northwest Outdoor via eBay offers the factory-refurbished Goal Zero Nomad 7 v1 12-volt 7-watt Solar Panel Charger, model no. 12301, for $32.99 with free shipping. Although we saw it for $3 less two weeks ago, that's still $20 under the lowest total price we could find for a new unit. (Most retailers charge $80.) It features USB and 12-volt DC charging ports. A 90-day Goal Zero warranty is provided.
