Frequently Asked Questions

Can you use an EcoFlow power station while its charging?

EcoFlow power stations can be used while they are being charged. The units support discharging while connected to an AC outlet , a car charger or a solar panel. However, when the device battery is critically low or about to run out, it is better not to use it while connected to a DC charger (solar/car charging). At this time, if the outlet power is lower than or equal to the output power, the device will continue to consume power, which may cause the battery to perform insufficiently, and eventually damage the battery.

Can you use a third party solar panel with an EcoFlow power station?

EcoFlow power stations are compatible with most third party panels. You will need to use the solar input information provided with your power station as a guide when choosing a compatible panel, and, of course you are welcome to contact us to check compatibly.
1. Things to note:

*Volts are pushed into your electric device so never over volt. Amps are pulled so the device take as much as is needed. Amps can get hot so always err on the side of caution.

2. Your main checks are:

VOC (Voltage)
Amps
Watts
MC4 connections
No solar controller on the panel

How can I get a guestimate of the runtime of my device with a power station?

Allowing for a slight inefficiency in the inverter, we use this calculation for a guestimate:

Wh of the power station x 0.85 / the watts consumption of your appliance.

Eg. with the River 2 and an 80W device:

256Wh *0.85 / 80 = 2.72

Eg with the Delta 2 and a 100W device:

1024Wh *0.85 / 100 = 8.7

How should I store and maintain battery?

1. Please use or store the product in an environment temperature between 20°C to 30°C, away from water, heat, and other metal objects.

2. For long-term storage, please discharge the battery to 30% and recharge it to 60% every three months; products that have not been charged and discharged for more than 6 months will not be covered by the free product warranty.

3. For safety, please do not store the product in an environment temperature higher than 45°C or lower than -10°C for a long time.

4. To prolong the battery life, please use the product in an environment temperature between 20°C to 30°C.
