Found this little guy on Tigerdirect.com listed as $59.97 with a $50.00 discount. Too good a deal to pass up I assumed. So I ordered a couple of them.
First of all, at the full (Supposedly retail?) price they are not worth the cost. However, most internet searches turn them up at between $9 and $13. I would buy these at up to $12 but no more.
First of all a little description. This is a combination solar charger/battery pack. It has a battery (not a very big battery). Some nice features for such a cheap device.
It comes with a USB charging cable (To charge from a USB port), and adapters for several of the current run of phones and MP3 Players. It also includes an embedded sollar cell to charge the battery in the field.
I spent a week at scout camp and did some testing with this device. I will say right out of the box that it is a little underpowered for my phone. I use an HTC Touch pro 2 smartphone and from dead battery, this device (fully charged) got me about 1/3 to 1/2 a charge which is good for the price.
The solar cell produced enough voltage to show charging on the phone, however, after 1 hour of solar charging (on a dead battery on the device) in direct sunlight, it only charged 20% on the phone.
This is what I would call cheap insurance. I put one of these on the dashboard of our vehicle and its always charged and ready to go, throw it in a pack or pocket and head out the door. It will run your phone in an emergency just fine. Or get you the extra 20 minutes needed to finish a call etc.
All in all, its a great device for the cheap price. I now have 4 of them and give them as gifts to other family members.
