From Athena - "GET JumpStarter is a multi-functional mini starter which allows you to restart any motorbike and scooter (including watercraft and small boats)when they’re out of battery. Light and compact, JumpStarter has a LED torch included. It can also be used as a Power Bank for your electric devices thanks to the USB output port 5V/2,4 A which allows you to connect to tablets, smartphones, MP3 etc. JumpStarter is extremely easy and safe to use as it is provided with a special protection against over-voltage and inversion of its power supply polarity. With JumpStarter nothing will ever stop your ride again!"
