    I’ve had it for 2 years and only used it for a small handful of trips making sure to take good care of it and all of a sudden it has stopped taking a charge. I have tried multiple outlets, cords and bricks and it still doesn’t charge.

    Both the product description on the website and the product box state that there is a travel pouch included. However, there is not a travel pouch included. Need to properly represent the product being sold.
