"The BigBlue SolarPowa 30 impressed during testing, generating 17.8 watts of power out of its USB-C port under sunny skies and clocking 5.5 watts in the shade. That means it should reliably charge your phone in most conditions."

"Cellapowa 2500 has got faster-charging speeds as one of the notable highlights. With its 1200W AC and 1200W solar charging inputs, you can charge it quite faster from the combination of the two."

"This 28-watt model performed better in variable conditions than every other panel we tested. This was consistently one of the most effective and efficient portable solar charger models across every one of our tests."

"I really appreciate the overall flexibility of the panels, you can lay them on uneven ground, prop them up with the kickstand, or hang them from a vehicle or structure from the built-in eyelets."

"BigBlue’s Cellpowa 500 is a slick power station that complements any workspace with best-in-class battery chemistry and an array of output ports."

"The BigBlue 5V 28W solar charger also has a convenient fold up design that can be stowed in a pack or opened up for use on the trail, and even has a built-in voltage regulator."
