THE AP175
The 4 solar panels are folded into what seems to be a large envelop made out of nylon (a magnet keeps the envelop folded).
When the solar panels are unfolded the AP175 measures 71cm in length, 16cm in width and 1cm in height (notice the 5 loops located at the ends of the panels - these can be used to attach the AP175 onto surfaces by using the bundled carbine).
I really can't comment on the whether or not the solar panels of the AP175 are of the same quality as those found in regular photovoltaic models but i can say that they are of very high quality.
Turning the device/envelop over we find two USB charging ports and two elastic bands all placed under a protection net.
Although this area may not be large enough for a 10" tablet you should be able to fit a couple of large phones without problem (our ZTE test phone features a 5.5 inch screen).
