This is a really cool combination of technologies. I was impressed with how light-weight this flashlight is. It shoots a good, beam of light. The flashlight was fully charged with in an hour using the USB charger. Have not checked out the solar charging yet because I'm still using the first charge (been sitting in a drawer about a month and been used maybe an hour so far). I have not tried charging a device from this light either but am very encouraged with the product so far. If the technology holds up and I do not have to replace the light for a couple of years, it is well worth the price.
