Design and functions:
I live at the end of a circuit and any problems upstream will result in loss of power to my home. I can’t tell you how frustrated it is not to have power but still look across the street and see my neighbors go about their business with no worries. In some cases, friendly neighbors have allowed long extension cords to keep freezers thawing, running sump pumps to prevent flooded basements, and even powering a house’s heater to warm up before it gets through a long, cold night and around prevent the pipes from freezing.
Because I “was there, did that” I am a little pressed to have a backup power plan. I have a generator, but it’s awkward to hook up (especially frustrating if the blackout only lasts a few hours), uses a fair amount of fuel, the exhaust is toxic, it’s noisy, and it requires maintenance to keep it running. Transporting and storing the gas is a torture, and to top it all off, I hate the smell, yuck! I’ve been slowly saying goodbye to fossil fuels and even have an electric ride-on mower and hybrid car to cut my gas mileage as much as possible. Now only my snow blower and backup generator are using gas. Not using gas has another big advantage – the Delta Pro can be stored and used indoors without exhaust gases, without the risk of carbon monoxide poisoning and without noise (except for the cooling fans).
For several years now, I’ve taken several stopgap measures to address power loss issues – I’ve used USB batteries to keep phones and computers running, inverters on a dead car battery to keep my oven running, and various small options to keep my freezer cold and to keep the sump pump running to prevent my basement from flooding. If necessary, I light a generator to keep several things running at the same time. Sure, it is possible to buy a large generator or a roof full of solar cells and backup batteries for home power, but these solutions are comparatively expensive, require professional installation, and have their own maintenance problems.
Step into EcoFlow… I was accordingly impressed when I discovered EcoFlow’s offerings on Kickstarter and took the opportunity to get my hands on one of their products.
The EcoFlow Delta pro came in a sturdy box with foam inserts. Rugged is definitely required as the Delta Pro is a beast at almost 100 pounds.
It’s not something I want to lug around with Higglety-Pigglety, but the EcoFlow design team thoughtfully added a luggage-style pull-out handle, padded handles, and strong wheels to make portability a little easier.
EcoFlow includes multiple charging cables for standard AC outlets, in-vehicle charging, and solar power, although solar panels are optional accessories. As an electrical engineer, I was admirably impressed by the charging voltage and current ranges.
Charging this mammoth power plant from an electrical outlet is shockingly fast! According to my ammeter, it drew a spike of 14.8 amps while charging – that’s a full 1800 watts and is powerful enough to be fully charged in just over 2 hours on a 120-volt outlet. Very impressive! But wait … there is more! … The app enables individual charging levels if your system is limited in its current strength, for example in motorhome parks, which limit the socket usage to 15 amps and the circuit has to be shared with other devices.
Equally impressive is that the Delta Pro can charge from AC and DC power supplies at the same time AND can output power at the same time. That’s a big plus in my book! This means that the portable power station can draw power from a car socket or solar panels *, convert it to the USB or AC power it needs, and pump excess energy that is not used by the outlet back into the battery – using and charging at the same time.
You may be wondering, “Why is it so important to charge and use at the same time?”
Firstly, because the Delta Pro’s inverter output is very … very … clean, perfect sine waves that translate into happy, healthy devices. Sine wave current, AC (Alternating Current) is what your home uses. Motors and other loads are designed to perform optimally with this type of power. Unfortunately, some inverters (power converters that convert direct current (DC) to alternating (AC) current) use a “modified sine wave” which causes the normally smooth current to have “steps” instead of smooth waves. These “steps” in the power supply can cause the loudspeakers to hum, which is hotter than normal operation, and even lead to the failure of sensitive electronics (e.g. computer power supplies). EcoFlow’s design ensures that this doesn’t happen.
Simultaneous charging and dispensing reduces the guesswork and the swapping of cables if things keep going – once the connections are made, power automatically flows in and out of the Delta Pro system without fiddling with cables or plugs. If there is enough power to charge the Power Station and the batteries have enough capacity to power the connected devices, it just works.
To make the system even more versatile, the Delta Pro can be charged using an adapter at electric car charging stations and a gas-powered smart generator *!
The input connections are located on the “tail” of the Delta Pro.
The Delta Pro’s outlets are in abundance and power anything I could throw at it – my freezer, refrigerator, fan, television, and even a 1800 watt microwave were no problem. Even at 1800 watts, the Delta Pro could have powered my microwave for two hours!
Converted into smartphone numbers, the Delta Pro should be able to fully charge my iPhone 12 Pro an incredible 250 times!
EcoFlo has an interesting solution for devices HIGHER than 3600 watts without overload – X-Boost lowers the output voltage and current for inductive loads (such as drills, hair dryers and waffle irons) to enable the device to operate. Very smart!
To increase its usefulness, the Delta Pro can be expanded with two additional optional external batteries and a home connection kit *. This is especially noteworthy as it not only increases system capacity, but also allows the voltage to be increased to 240 volts two-phase power. This means the Delta Pro can power ALL the devices in your home, including your oven, tumble dryer or electric oven. I don’t know of any other inverter-based backup power system that has this capability. Wow, EcoFlow, Wow !!
The bright, multi-colored display of the Delta Pro provides the percentage of available power, the input and output power, an estimate of the remaining time with the current power consumption, the status of the connected device, indications and warnings.
To sweeten the experience, the EcoFlow app is fantastic! All functions of the Portable Power Station can be monitored, ports can be switched on and off.
Even more app options can configure practically everything on the Delta Pro, as well as update software.
The app even has a full specifications section. I love it!
* EcoFlow didn’t include an Extra Smart Battery, Smart Generator, Delta Pro Remote Control, Dual Voltage Hub, Solar Panels, or EV X-Stream EV Charging Adapter, but this system is so impressive that I’d be amazed to check it in Future!
What I like
- Lightning fast loading
- Loads of input and output options
- Modular and expandable
- Outstanding performance!
What I would change
- Nothing! This system is amazing! The engineers at EcoFlow have thought of everything! The system is crazy modular, expandable and terrifyingly innovative!
EcoFlow’s Delta Pro is one of the most innovative, efficient, and best-designed products that I have had the privilege to test. It’s incredibly powerful, the design and features are exceptional, and its expandability is just amazing! Bravo, EcoFlow, Bravo!
