Do not purchase this. Super bad build quality! Nothing more than a badly built, super thin back pack with a crappy battery pack thrown it in. Has ZERO padding for protection, the latches are poor quality, the battery pack looks super shady, the charging (input) cable for the battery pack is integrated into it and not removable. Neither of these are worth $30.
Thank you! You just saved me $30 plus shipping! I was about to go for it.
