What can the DELTA 3 Max power?

It runs fridges, lights, laptops, phones, fans, TVs and power tools, and with X-Boost it can handle some higher-wattage appliances within its output limits. Heavy resistive loads like space heaters or large microwaves may exceed what it can sustain.

How long does the battery last?

EcoFlow rates the LiFePO4 battery for thousands of charge cycles before capacity drops noticeably, which is far longer than typical older lithium-ion packs. Actual runtime depends on the load you connect.

Does the 400W panel charge it fully?

The panel can deliver up to 400W in ideal sun, but real output is usually lower due to angle, shade and heat. Expect several hours of good sunlight to recharge a large station from empty.

Can I charge it from a wall outlet and solar at the same time?

EcoFlow stations support combined charging from AC and solar on many models, which shortens recharge time. Check the input limits for this model before combining sources.

Is it good for home backup?

Yes for short outages and essential loads like a fridge, lights and router. For whole-home or multi-day backup, a larger system or a generator is a better fit.
