"keep the one that performs best"
The technology behind them is all about the same. All solar cells are fairly similar in performance. All the consumer really needs to know is what is the power output of the gizmo, what is the storage onboard (if any) and then do the math. Compare reviews (on Amazon or other sources) to see if one is poorly made or not, but take the reviews with a grain of salt because a lot of the reviewers don't understand basic concepts. Which is why Apple won't let them change an iPhone battery without adult supervision.
