    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 charged my Iphone twice, and I still have 4 blue lights lit. It was easy and worked fine. With STP discounts, its a great buy and well worth the peace of mind Ill have this winter. Just what I was looking for.

    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.

    The Brunton Sync thingy is a really nice piece of equipment. I bought the i6 Solar charger to charge up my phone. But it didn't work with my iPhone. It worked with my wife's iPod. But not with the iPhone. After talking with the Tech Support guy at Brunton, he said that the iPhone needs a consistent charge. So, even if you get the solar panels working to charge your iPhone (the provided cable with the solar charger doesn't work. You have to use a converter like the one I happened to have from Griffin Technologies), it will take a long, long, long time--like days-- to charge up.

    The solution is this power sync. It's a little heavy for light hikers. But the solar panels work great with it. And it charges my iPhone great. You plug in the white usb cable that came with your phone into the usb slot/port thingy, and then push the power button. It then charges your phone.

    Having two separate units connected by a cord is a little weird. But, if that's the only con, (hence 4 stars instead of 5) it's not that much of a downside at all. A really nice device to have to power up your portables.

    It doesn't seem to charge a smart phone as many times as it claims, but it will charge a smart phone a few times. 3 or 4 times. But... if it moves, wiggles, bumps, or anything, it will stop charging! That makes it not very useful for backpacking. I tried it on my night stand several nights and I had to fight with it to get it to charge throughout the night. Then on the way to a camping trip, I tried to charge my phone in the car while driving 6 hours. Any little bump or disturbance and it stopped charging. I left it in the car, didn't even take it out for the camping trip. I am not impressed and will likely return this item.

    It WILL charge my SmartPhone (Motorola Cliq) about 4 times. BUT... it has to be left sitting PERFECTLY STILL! It can not be moved AT ALL or it will quit charging. I can not imagine how it would charge something while hiking with it in your back pack?? I have not taken it outdoors. I charged it with the wall plug, then put it on my night stand to charge my phone over night. Any time I bumped it or nudged it, it would shut off. I don't know if there is a wire loose or something?? Maybe it is just this particular one?? But I will be sending it back. Not sure if I will try to get a replacement or a refund??
