Ian , i may have been with you out of Loch Ness over East when you corrected me with your rechargeable kit into the upper river system for the Monadhliath . I thought it superb and am only now admitting WEIGHT is a significant factor . thanks bill h.

Hi
I recently bought an Anker Astro 6000mAh from Amazon for £26 for use on the event. Last week I charged 2 Android phones and an iphone 5s and it still had some juice left in it. Weight 132g.
