This review is from: Opteka BP-SC4000 4000mAh Ultra Thin Solar Powered High Capacity Backup Battery Charger + 10 Charging Tips
Pros:
Battery when fully charged from the wall will charge my Galaxy Nexus once, with a bit left over. Feels light, but thats probably because the internal battery doesn't appear to take up the whole case.
Cons:
I left the charger outside in direct summer sun for 12 hours and it was only able to charge my phone 20%. In an emergency this might be enough I guess.
Overall Review:
The manual isn't very clear. In order to charge your devices the battery pack must be powered on. To do this hold the power button for approx three seconds. Do the same to turn it off when you are done charging your phone so the LEDs don't drain the battery.
