Consumer warning: I bought a Wireless Lit Solar Powerbank from LitMobile. It never worked properly. Even after more than 15 hours of solar-charging, the battery never got above 50%.
I emailed them to exchange it for another unit (or possibly request a refund). They referred me to RMA@LitMobile.us, which I then emailed. Never heard back from them. That was two weeks ago.
