People say Bigblue is really similar to Goal Zero.
great Quality on par with my Goal Zero at less ...
Got this for my parents in Puerto Rico after the storm in 2017, I played with it before I sent it out. great Quality on par with my Goal Zero at less than half the cost. Planning on getting one for myself to power my Ham HT radios out in the field.
Surprisingly quick charge
Replacing a smaller Goal Zero Nomad solar charger which was too slow - first charge using Bigblue on a Los Angeles spring morning and was very pleased with how quickly it charged my iPhone. Will be a great addition for camping.
