I do not think it is appropriate in this Anker forum to promote non-Anker products.
I would say Anker should:
- modify the product to be using the reverse side of the solar panel for its non-solar aspects like the USB sockets, this removes the panel with basically just fabric, saving weight.
- make a zipped pouch rather than velcro. It is the same size but allows for either cables or a small Powercore to be stored securely, and when the temperatures are low (morning sun) to store your recharging device (phone, Powercore, etc) to be kept securely together.
- consider its prices. For the solar products, they seem somewhat high. In some countries it is more than double the price. I like Anker's customer service quality, but not that much!
- consider the metal grommet placement.
Anker uses the same solar cells as others.
I would also like Anker to consider making their solar panels in a white fabric so there is a little less heat for when you are keeping the device nearer the solar panel.
Anker's solar products perform extremely well, they are well reviewed, and I would be happy to help Anker make their products even better.
