Solar charger

I have been yrying a couple of things to try to go more solar in my life.  One of these is to try to find a good solar charger.  I purchased two solar chargers from china wholesalers.  The first totally didnt work and then the second didnt work either.  The customer service peeps said to charge it with the regular power source (plug into the wall). That did work to charge my phone, though not solar.
I also got a gift of a solar lamp which is like a super bright camping lantern.  This lamp has a plug in function for the phone to charge but it hasnt seemed to be working to charge.  This is weird because the light works and i dont know why that power will not transfer to my phone.
I guess i have to find like a better made one.
