Our take on the EcoFlow DELTA 3 Ultra Plus Portable Power Station + 400W solar panel

The EcoFlow DELTA 3 Ultra Plus is a high-capacity portable power station paired with a 400W folding solar panel. It is built for home backup, off-grid living and long trips where you need to run fridges, power tools or a whole room for hours. The bundle adds solar charging so the station can refill without a wall outlet. Against smaller DELTA models it offers more capacity and output, but it is heavy and best treated as a semi-portable unit rather than something you carry on every outing.

About the EcoFlow DELTA 3 Ultra Plus Portable Power Station + 400W solar panel

The EcoFlow DELTA 3 Ultra Plus is a portable power station with 3,072 Wh of storage and a 3,600 W rated inverter (7,200 W surge). It can run heavy-duty appliances such as refrigerators, power tools or an RV panel. The Smart Output Priority feature lets you pre-set essential loads, such as a fridge or router, to stay powered when power is limited.

It is built with automotive-grade full-tab LFP battery cells rated for over 10 years of use. It is made to withstand harsh environments, including humidity, salt spray and drops. A 10 ms automatic switchover (UPS) helps protect sensitive electronics.

The bundle includes a 400 W portable solar panel. It is a foldable, one-piece panel with monocrystalline cells and up to 23% conversion efficiency. Its protective case doubles as an adjustable kickstand, and the panel has an IP68 waterproof rating.

Questions and answers

How long can it run a refrigerator?
Runtime depends on the fridge's draw and duty cycle. A typical full-size fridge averages well under 200W, so the station's large capacity can keep it running through a long outage, often a day or more. Check your fridge's rated watts and annual kWh for a closer estimate.
Can the 400W panel fully recharge it in a day?
In strong, direct sun the 400W panel delivers close to its rating, but real output drops with clouds, shade and panel angle. Expect a full recharge to take most of a clear day, and longer in mixed weather.
Can I use it indoors during an outage?
Yes. It produces no exhaust fumes, unlike a gas generator, so it can run indoors. Keep vents clear and avoid enclosing it in a tight cabinet.
What can it power at once?
It can run several devices together, including a fridge, lights, router and phone chargers, and can handle high-surge appliances like a microwave or power tool. Add up the running watts and check the surge rating of anything with a motor.
Does it work with other solar panels?
It accepts solar input through its solar charging port, so third-party panels with compatible voltage and connectors can work. Match the panel's voltage and current to the station's solar input limits.
