stop to protect vehicle
24V <26V starter battery from
48V <52V over-discharging

1. Vehicle Alternator Charging will only operate when vehicle is on move. If idle
charging is needed, user can toggle the idle charging button via EcoFlow APP.
2. Connect ALT IN1 port as a priority for vehicle alternator charging.

Priority of multiple charging

Power Hub supports multiple charging input simultaneously, and the charging
priorities are: solar charging, AC charging, vehicle alternator charging and EcoFlow
smart generator charging.
The total charging current at the battery port of the Power Hub is limited to 100A.
When the charging input power is greater than the power required by the battery,
the charging input with lower priority will reduce charging current smoothly or even
stop charging.

X-Boost Feature

With EcoFlow X-Boost technology, this product can power a 5200W Max device (for heating
appliances only) while the rated output power remains 3600W, avoiding operation failure
due to overload protection.

1. The X-Boost feature is unavailable when AC Output is in bypass mode.

2. The X-Boost feature is not suitable for all appliances. The X-Boost feature is
only suitable for heating appliances. It is not suitable for some appliances with
voltage protection, such as precision instruments.

Bypass Mode
When the product is connected to external AC and the AC output is enabled, the system
enters bypass mode. The AC output is provided by the external AC power supply and the
LFP battery is charged by the external AC power supply.
When external AC is not available, the Power Hub will automatically transfer to inverter
mode, AC output will restore power within 30ms.
