It does the job well

Fully charged, this charger adequately charges my phone, wi-fi hotspot, or phone battery pack very well. It is best if you turn off whatever you need to charge. I wanted a different model with twice the solar panel area, but those were sold out quickly. As long as you find an open area to charge by the sun, you'll be satisfied; but it will take 3-4 hours of sunlight for a full re-charge. When charging this pack by USB, car charger or electricity, 1.5 -2 hours will fully re-charge.
