Watts tell you what it can power. Watt-hours describe battery size. Some charge is used by the station itself, so actual running time will be shorter than a simple battery-size calculation.

Who should consider the EcoFlow DELTA Pro?

The EcoFlow DELTA Pro is a rechargeable battery power station. It is listed to supply up to 3,600 watts for plug-in appliances. Add up what you want to use together and check the extra power needed when motors turn on. This package lists a 3,600Wh battery. How long it lasts depends on what you plug in and how often you use it.

This station stores 3,600Wh and accepts up to 1,600W of compatible solar charging. It weighs about 99 pounds, so plan how it will be moved. The US single station is marketed for 120V use. A 240V system needs the correct additional equipment. A 400W panel package alone does not reach its full solar limit.

The details for this model

These details refer to Amazon product B0C1Z4GLKS. Check the full model number and included equipment before ordering. Similar names can describe different batteries, panels, or voltage.

Most household plug-in appliances use 120V. Battery life may be listed in charging cycles: one cycle is roughly a full battery’s worth of use and recharging. Switching time is sometimes shown in milliseconds (ms); a small delay can still restart some devices. The detailed plug codes below are for checking the matching manual or asking the manufacturer.

How long might the battery last?

This package stores 3,600 watt-hours (Wh) of charge and can keep supplying up to 3,600 watts (W) through its household outlets. A heater may fit under that power limit but still empty the battery quickly. The estimates below start with a full battery and no recharging. They allow for some power lost while converting battery power for household plugs (15%), plus 10 watts used by the station itself. We have not measured these running times.

500W6.0 hoursCheck any extra power needed to turn on
1,500W2.0 hoursCheck any extra power needed to turn on

A refrigerator switches on and off, so it may use less charge than a device drawing the same watts all the time. It still needs extra power when its motor starts. Check the appliance manual and, where suitable, use a plug-in electricity meter to measure daily use. Cold weather, battery age, and keeping spare charge can shorten running time.

How do you recharge it with solar panels?

11–150 V 15 A maximum,1600 W solar input. Station only; no solar panels documented; 3600Wh battery size in this package

Use only panels and connections allowed by the matching manual. A plug that fits is not proof that a panel is safe for the station. Cold weather can raise panel voltage, and adding panels changes the electrical limits. Ask the manufacturer if you are unsure. Clouds, shade, heat, and panel angle affect charging speed. Keep the battery dry and give it the airflow the manual requires.

1800 W at 120 V 15 A;3000 W at 240 V 12.5 A withappropriate charging arrangement. Manufacturer advertises 2.7 h US 120 V/1.8 h 240 V. Advertised charging times depend on the charger, sunlight, temperature, and how empty the battery is. Use wall and solar charging together only if the manual allows it.

What to know about everyday use and support

We do not have enough owner feedback for this exact model to give a fair summary. Check recent reviews for the full model number and ask the seller how service and returns work.

Exact warranty coverage for this offer remains unverified. Check that your seller and intended use qualify for the warranty. Ask who pays shipping for a repair. Practice with the devices you plan to use overnight. Some stations turn outlets off when very little power is being used. The cooling fan may also be audible even though there is no fuel engine.

We have not confirmed how quickly it can switch to battery when household power goes out. For medical equipment someone depends on, arrange a backup plan with its supplier.

Other packages for this model

These offers may include different panels or extra batteries. Check the full package before ordering, because that changes the weight, price, and how long it may last.

For another way to keep power available during a long outage, compare the gas-generator directory. Fuel generators must run outdoors at least 20 feet from homes and openings, with exhaust pointed away. Battery models do not produce engine exhaust, but still need safe charging, dry conditions, and correct connections.

EcoFlow DELTA Pro: common questions

Does EcoFlow DELTA Pro include solar panels?

Station only; no solar panels documented; 3600Wh battery size in this package Check the exact package you select. Other offers for the same station may include different panels or none at all.

Do watts and watt-hours mean the same thing?

No. 3,600W is the power limit for household plugs. 3,600Wh describes the battery size in this package. An advertised boost mode does not guarantee it can start a refrigerator or pump.

Can I connect it to my house?

Its documented output voltage is 120 V / 60 Hz. An electrician must check whether it suits your home and install the correct transfer equipment, which safely separates backup power from utility power. Never send power into a household wall outlet.

Will it run all night without sunshine?

It uses the charge already in its battery after dark. Solar panels do not recharge it at night. How long it lasts depends on what you plug in and how often those devices run. Check your appliances and allow spare charge.

Our take

Check what it can run and for how long.
