How to charge DELTA/RIVER?

You can charge RIVER/DELTA by AC input(regular wall socket)or DC input (car charging/solar charging).
For AC input charging use the AC charging cable to connect the power station to the wall socket to charge the unit.
For Solar charging, connect the power station to the solar panel using EcoFlow MC4 to XT60 Solar Cable (which comes with the power station), make sure the solar output of the solar panel matches the solar input of the power station (400W 10-65V DC 10A max for DELTA and 200W 10-25V DC 12A max for R600/River 600 series).
For car charging, connect the car 12V output port to the power station using EcoFlow Car Charging Cable (which comes with the power station), and make sure the current coming from the car is not above 8A (or set the car charging current from the app to 8A).

Can I take RIVER/DELTA on the plane?

Only RIVER RAPID and RIVER BANK can be taken on a plane. Other power stations can’t be taken on a plane due to the Federal Aviation Administration (FAA) rules that only allows multiple lithium-ion batteries up to 100Wh on planes.
