This year I took two chargers and cables, both of which I'd tested as good at home. Both of which gave problems again! Even bought a charger locally "just in case" and it made no difference.
Luckily I had the bike set up so there was a charger in the tank bag powered by the bikes socket, which worked a treat, so I had the bike charge it during the days riding.
The USB chargers I had worked perfectly on the BMW comms system in the helmet. But would be flaky charging the 'phone.
One hotel, The Garvault Lodge Hotel in Kinbrace I accepted would probably be problematic as it's listed as the UK mainlands most remote hotel, doesn't have mains water, mains electric, TV's etc. Although you could get internet access from one corner of the hotel

Anyway back to the question has anyone else had any charge issues or is it just me

Oh of course once back home the 'phones all charge as per normally
