FAQ Troubleshooting
Why doesn’t my DELTA charge to 100%?
You can do SoC (state of charge) calibration by fully discharging and recharging the battery.
What should I do when DELTA can’t charge from my car outlet?
1. Make sure your vehicle’s engine is on when trying to charge DELTA.
2. If other devices with a car outlet plug don’t work, it could be a problem with your car outlet.
3. If a solar panel or a third-party XT60 cable can charge DELTA, it could be your XT60 charging cable.
Can I use DELTA as an uninterrupted power source (UPS)?
No, but it can be used as an emergency power source (EPS). Here’s the difference.
When your DELTA is plugged into the wall, anything plugged into it gets power from the grid, not its battery. If power from the grid stops, DELTA automatically switches to its battery supply mode within 30 milliseconds. That means anything connected will not have power for 30 milliseconds, which may mean desktop computers and data servers turn off. UPS is not necessary for most devices, but you’ll have to determine this for yourself.
Why are the icons on the LCD screen dim?
Place DELTA on a hard surface.
Why does DELTA power off automatically?
1. The battery may have died.2. DELTA will automatically turn off if the AC and DC power buttons are turned off, and there is no input or output power for 30 minutes.
What should I do if DELTA won’t turn on?
1. It might not have enough battery. Try charging it and restarting it.
2. If DELTA’s battery went to 0%, you might see an overheating protection icon on the LCD screen. Wait for the unit to cool before recharging it.
Can I link the EcoFlow Smart Extra Battery with DELTA?
No, but you can connect up to 2 DELTA units for twice the battery life.
How do I connect two DELTA units together?
1. Fully charge both DELTAs.
2. Make sure they’re disconnected from the wall when being used.
3. Plug one DELTA into the other’s AC wall outlet.
