Cingular Go Phone: Tenergy USB-5000 Hybrid Solar Charger for Mobile phone, iPod/MP3 Player, PDA, Game Player, GPS and Digital Camera Review

have had this for a little over 2 weeks and it works good. it even gives a slow charge to batteries under normal indoor light. I tried it outside and it charges batteries fast and with no batteries in full sun it charges my cell phone well through the usb port. indoor light is not enough to run the USB with enough juice to charge a phone, but it does charge batteries indoors and can use the batteries to charge a USB device.
Under solar power only it is not enough to run some of my higher demand devices but it does most fine, and when running of 2 AAs it runs the USB hot enough to charge most anything I have.
All in all it seems a good unit and I paid less than $20 for it with shipping I recommend it to all my friends,
The only design flaw is that the little loop at the top is not quite big enough to fit a carbeener through so I had to attach a keyring to it in order to clip it to the outside of my pack. perhaps in the future they can mold it with a slightly larger opening.
