solar battery charger

Hi.
I would like to buy a phone USB charger which I can charge with solar power when I'm cycling ,putting it on my small backpack.
I wonder if anyboby knows a good charger.I read many comments on internet about the low quality of that.
Does anyone help me to choice one ?
Thanks in advance ;)
Robert.

Bootstrap Solar

I don't know your budget and weight limit, but I used this one. So far it never let me down.

I used it for 10.000 km from cold to hot, on the bike and on my backpack.
The battery capacity might be a bit overkill, but if you plan on using GPS you can charge it too.

Cheers

or

You could get a hub dynamo and USB attachment. More expensive than a solar charger, but I have one and it works well. I suspect this would charge quicker than a solar and of course, it works when there is no sun.
