The explorer solar panel is a dissapointment compared to other folding weather proofed panels such as the panel made by Sunlinq or even your own panel. The Explorer solar panel certainly looks rubust enough though. What I do like is the actual Powermonkey Explorer itself. The charge display panel is a great idea. What I would look for is a 12V to 5V high effieciency convertor to link a Sunlinq panel to the Powermonkey Explorer. The Powermonkey Explorer device is actually not that bulky or heavy in comparision to other similar sized universal Lithium Ion batteries although the form factor is probably dictated by the cylindical Li-ion cell at its heart. I do find it strange that they don't appear to have an adapter to power the Powermonkey from a 12 car cigarette adapter though.

Its the wide range of Monkeynuts and international mains power adapters which make this a useful device. Monkeynuts can be purchased separately to increase the range of devices which can be supported.
