Solar powered bluetooth car kit set is really a great product that allows hands-free operations of the cellphone when you are driving. This is a really great little device. It's very easy to operate. It charges by solar power, car lighter or USB. This Solar powered bluetooth car kit has got a excellent design and style, excellent telephone quality, lcd display as well as built in speaker. This is one of the best product I have bought simple to operate and calls are nice and clear and easy to answer. You don't need to worry about charging because sun is the better strength we've got. I do believe you should buy this product from our china wholesale market.
