I am a bit dissapointed with this product as with solar charging it will only achieve a 3/4 charge after hours of direct sunlight exposure. I am considering returning the panals and the battery pack. I have even hooked 4 panals to the parent device with no charging improvement. A bit dissapointing.

This was a decent unit but did not significantly increase the solar output while charging my Galaxy Note 2 smart phone.

My estimate is to expect about 2.5 times the output with the solar charger, but that is not a huge jump in total solar output.

So it's decent but not sure if this would be worth the price you pay for it. But I'm intrigued and might get another two add-ons.

These help the ReVive charge faster, but it's still slow to charge a phone. I suspect that all small solar charges like this aren't really worth it, but are cool in concept.
