Awesome to have power to charge phones for a couple of days so no need to panic if you can't get to an electric point.

    descent product but you can find better for less out there. there's lots of small solar chargers for charging cell phones and mp3 players and other small devices that are much better and cost a lot less. when I'm camping and hiking I can care less about what name is on my gear for other people to see as long as its quality and serves my needs.

    I've only used it once, at home, to make sure that it works. The unit charged in 4 hours from an AC wall outlet(as advertised), and then my Android phone (HTC Droid Eris) charged from it overnight. I haven't verified the time it took to charge the phone, but it was less than 7 hours, and I would expect that it was within the 1-2 hours advertised; the sync was off when I checked in the morning thanks to the auto-shutoff feature.

    The sync control is still showing between 75%-100% charge remaining. They claim that I should be able to get 5-6 "smartphone" charges from a single sync charge; We'll see...

    At 12oz., it's not ultralight, but it's well worth the weight if you need portable juice.

    Overall, it works as expected so far. I'm giving it 4 stars because I was surprised to read, on the package I received, that it's good for only about 500 sync charges. That was a surprise.

    While the design and the promised features looked good, the electronics were poorly designed. Did not stay powered up when turned after only 2 uses. Was charging an iPhone 3. When it was on, very sensitive. Couldn't move it or it would lose connection. Two part system is cumbersome. Will be going with a solar mat. Not worth the purchase. Sent back. Sierra's return policy is incredible.
