I have two power banks. An Anker Powercore 20100, capacity 20100 mAH. Output 5v-4.8A. Also an Anker Astro E1, capacity 6700 mAh. Output 5v. Both have intelligent charging.
When I try to charge my Sena SRL ( Sena 20S ) with either power bank the charging light comes on for three or four minutes and the the unit switches off. What do I need to charge a headset away from mains power without using the bike battery?
