Design and Features:
I live at the end of a power circuit and any problems upstream result in a loss of my home’s power. I can’t begin to tell you the frustration of having no power, yet being able to look across the street and see my neighbors going about their activities without a care. In some circumstances, friendly neighbors have permitted long extension cords to keep freezers from thawing, sump-pumps running to prevent flooded basements, and to even power a home’s heater to warm things up before lasting a long, cold night and help prevent pipes from freezing.
Because I’ve “been there, done that,” I’m a bit OCD about having a backup power plan. I have a generator, but it’s cumbersome to connect (especially frustrating if the power outage is only a few hours), consumes a fair amount of fuel, the exhaust is toxic, it’s noisy, and, it requires maintenance to keep it going. Transporting and storing the gas is a pain, and to make matters worse, I hate the smell, yuck! I’ve slowly made the move away from fossil fuels, and even have an electric ride-on lawnmower and hybrid car to lower my gas usage as much as possible. Now, only my snowblower and backup generator use gas. Not using gas has another huge bonus – the Delta Pro can be stored and used indoors with no exhaust, no risk of carbon monoxide poisoning, and no noise (except the cooling fans).
For several years, I’ve made several stop-gap measures to deal with power loss issues – I’ve used USB battery packs to keep phones and computers running, inverters with a bare car battery to run my furnace flowing, and various small options to keep my freezer cold and sump-pump running to prevent my basement from flooding. When necessary, I fire up a generator to keep multiple things going at once. Sure, it’s possible to buy a large generator or a roof full of solar cells and backup batteries for household power, but these solutions are comparatively expensive, require professional installation, and have their own sets of maintenance quandaries.
Enter EcoFlow… I was suitably impressed when I found EcoFlow’s offerings on Kickstarter and jumped at the opportunity to get my hands on one of their products.
The EcoFlow Delta pro arrived in a sturdy cardboard box with foam inserts. Sturdy is definitely required because the Delta Pro is a beast at nearly 100-pounds.
It’s not something I want to be lugging around Higglety-pigglety, but EcoFlow’s design team thoughtfully added a luggage-style extendible handle, padded handles, and strong wheels to make mobility a bit easier.
EcoFlow includes several charging cables for standard AC sockets, charging in a vehicle, and solar although solar panels are optional accessories. As an electrical engineer, I was admirably impressed with the charging voltage and current ranges.
Charging this mammoth power station from a wall socket is shockingly fast! According to my amp meter, it drew a peak of 14.8 Amps during charging – that’s a full 1800-Watts and is powerful enough to fully charge in just over 2 hours from a 120-volt socket. VERY impressive! But wait… there’s more!… the app allows for customized charging levels should your system be limited in its Amperage capacity, for example, mobile home parks that limit power socket usage to 15-Amps and the circuit needs to be shared with other gadgets.
Equally as impressive, the Delta Pro can simultaneously charge from AC and DC supplies AND can output power while doing so. This is a big plus in my book! This means the portable power station can pull power from a car’s power socket or solar panels*, convert them to the USB, or AC power needed, and any excess power not being used by the output is pumped back into the battery – simultaneous use and charging.
You might ask, “Why is simultaneous charging and usage important?”
For one, because the inverter power output on the Delta Pro is very… very… clean, perfect sine-waves that translate into happy, healthy gadgets. Sine wave power, AC (alternating current) is what your house uses. Motors and other loads are designed to work optimally using this type of power. Unfortunately, some inverters (power converters that change direct current (DC) to alternating current (AC)) use a “modified sine wave” that makes the normally smooth power have “stair steps” instead of smooth waves. These “stair steps” in power can cause buzzing of speakers and, hotter than normal operation, and even cause sensitive electronics (computer power supplies, for example) to fail. EcoFlow’s design ensures this doesn’t happen.
Next, simultaneous charging and output reduces the guesswork and cable swapping when keeping things up and running – after making the connections, power flows in and out of the Delta Pro system automatically without fiddling with cables or plugs. If there is enough supply for the Power Station to charge and enough capacity in the batteries to power the devices plugged in, it just works.
To make the system even more versatile, using an adapter, the Delta Pro can be charged from electric car charging stations and a gas-powered Smart Generator*!
Input ports are located on the “tail” end of the Delta Pro.
Outputs on the Delta Pro are aplenty, powering everything I could throw at it – my freezer, my refrigerator, a fan, TV, end even an 1800-Watt microwave was no problem. Even at 1800 Watts, the Delta Pro could have powered my microwave for two continuous hours!
Translating this into smartphone numbers, the Delta Pro should be able to fully charge my iPhone 12 Pro a staggering 250 times!
EcoFlo has an interesting solution for devices HIGHER than 3600 watts without overloading – X-Boost lowers the output voltage and current to inductive loads (like power drills, hairdryers, and waffle irons) to allow the device to operate. Very clever!
To increase the utility, the Delta Pro can be expanded to add two additional optional external batteries and a home connection kit*. This is particularly noteworthy because it not only increases the system capacity but also allows the voltage to be increased to 240-volts, two-phase power. This means that the Delta Pro can power ALL of the devices in your home, including your furnace, clothes dryer, or electric oven. I don’t know of any other inverter-based backup power system that has this capability. Wow, EcoFlow, wow!!
The Delta Pro’s bright, multicolor display provides the percentage of power available, input and output wattage, an estimate of the time remaining at the present current draw, connected device status, indicators, and warnings.
To sweeten the experience, EcoFlow’s app is fantastic! All of the functions of the Portable Power Station can be monitored, ports can be turned on and off.
Even more app options can configure virtually everything on the Delta Pro as well as update software.
The app even has a section providing the complete specifications. I love this!
*EcoFlow didn’t include Extra Smart Battery, Smart Generator, Delta Pro remote control, Double-Voltage Hub, Solar Panels, or EV X-Stream electric vehicle charging adapter for review, but this system is so impressive, I would be thrilled to review them in the future!
What I Like
- Lightning-fast charging
- Oodles of input and output choices
- Modular and expandable
