Planning a 4 day ride across the Quantocks, Exmoor, Dartmoor and home next month and want to navigate using breadcrumb trail on my edge 200 (before anyone tries to talk me out of navigating like this I've done it quite a few times and happy with it )
But I know my garmin will only last a couple of days, 3 at best. Has anyone used anything like this to charge a garmin?
The 'Anker' brand is pretty good, according to people in geo-stuff nerdery I've gotten involved in - various different sizes/prices, if you look them up on amazon.
One of mine is a fuel + PCPB30001 as it supports charge/discharge at the same time, so you can charge it from say a dynamo and charge your garmin at the same time. It cost about 8 quid.
Thanks for the comments, it was the power bar thing that got me thinking about the idea in the first place, a mate got one yesterday.
Some of those others look good, I'll do some more research and once I've bought one and tried it I'll report back
Time would be better spent getting the miles in instead of fretting about how many ml of meths to carry...
