Hello I bought a Tecknet Powerbank 9000mAh in order to power my arduino Leonardo that I will use to record values on a scooter. My problem is that a "powerbank" is mainly designed to charge a cellular phone and will detect when the phone is disconnected. The arduino draws very little current, so the powerbank auto shut off 30 seconds after powering. I found this article on internet : The guy who wrote the article have a R100 (0.1 ohm) resistor (current sensor) and replaced it with a 10 Ohm
