Backpack
Posted by JesseWould’ve been happier with a port for lightening cable for Macintosh products (iPhone/Apple tablets etc.) Now I have to buy a HDMI to lightening to device. Would’ve been better with having a lightening port on battery.

Replaced 5 year old version with broken straps/zippers
Posted by Sean DI replaced a 5 year old converter backpack with broken straps. The solar worked great, but the limited lifetime of the bag made me concerned about reordering. This updated version has higher quality stitching, and I like the new zipper style. It seems like this version is more durable... only time will tell. Only obvious drawback: side pocket opens in the wrong direction. If the bag is laying down, you need to flip it onto the panel to open the side pocket.

Well made and durable
Posted by LynneThis is the third product I've purchased from Voltaic and I'm impressed with how well made and durable they are. I've taken them backpacking and boating. If we are out on our boat all day, it's nice to be able to recharge a device if we are using it for reading. The people at this company are friendly, knowledgeable, and helpful!

Really nice backpack with solar charging a plus!
Posted by CathyI bought this backpack for my husband, who is commuting to work daily about 14 miles and starting to ride in darkness. First, the backpack is well-constructed with lots of pockets and large enough to carry his work clothes. He loves the charger. He charges his phone and his front light. I'm going to buy another one for myself!
