I'm going away for 10 days without access to wall power and taking a decent powerbank 100W output etc.
I can recharge that through USB access in the car I'm going to be in slowly. But I'm wondering if anyone knows of a way to keep the BP-A's charged through USB? I don't think I'll have direct access to the 12v car lighter, so looking for a USB charger of which Google is not showing any results.
Any advice gratefully received, it might not be possible, but thought I'd ask. Don't mind a third party charging solution etc.
Thanks
