You can check your energy storage power charging interface. The adapter we are equipped with supports Compatible with Anderson connector, DC 8mm adapter, 5.5mmx2.5mm (5.5mmx2.1mm) DC power plug, and xt60 connector charger. If the interface is suitable, it can be charged. 

The working voltage of the solar panel is 20.5V MAX, which is suitable for your power station. 

It should be. I’m using it with the Eco Flow River Max. I have only had it a couple of weeks but love it so far and wish I had discovered it earlier. It’s panel number 4 in my prep kit. I combine all 4 with my Bluetti AC200 and they charge it fully in 3 1/2 hours. The AllPowers charges the River in 4 hours. The River only takes one 200 watt panel. I know the Delta takes more but don’t remember the specs. Compared the prices to the name brand 200 watt panels, and the reputation of this, I had to try this first. This is a winner. Just check the specs on the Delta to see how many it would take. 

Yes, our accessories include an Anderson adapter cable. You can use the adapter cable to connect the solar panel to charge the energy storage power supply.
