Couldn’t be easier.
Works exactly as advertised - plug and play for more run time.

Dependable battery
Battery extension works like it says gives you more time for usage of power station, charges fast and can be used separately as a stand alone power to charge a laptop or phone. Good for camping and road trips .I highly recommend.
