I bought this a week ago so i could use my kindle during travel or when on the go. Unfortunately it had two problems, First was that there is not power button, and second i tried to charge it, as usual, by using the usb cord from wall AC plug, however, no matter where you lay it down, the light turns off. It came with 3 different options (battery, rechargeable cable & computer plug adapter) but only 1 worked.
Bad review
