anastasis constanti says:

That video was really helpful by putting all those devices head to head. At least now we know some lab test specifications , not what the companies are advertising and are not always true. Thanks for sharing with us !

Thank you!

Ron Bryant says:

Great review! thank you…. I now know not to get any of these pieces of junk… I’ll just get a real solar panel thats fairly portable and be good. I ride bikes a lot and just hanging a small panel off my back pack running to a portable charger would be much better . Great review!
