EcoFlow DELTA Pro vs DELTA Pro Ultra
In the realm of portable power, EcoFlow reigns supreme, consistently pushing boundaries with innovative solutions. Their DELTA Pro Portable Power Station stands as a testament to this, empowering off-grid adventurers and home backup heroes alike.
But with the recent arrival of the DELTA Pro Ultra, the question arises: how does the new champion stack up against its predecessor? In this article, we delve into the heart of these two power stations, highlighting the differences that define them.
DELTA Pro vs DELTA Pro Ultra Capacity and Output
The foundation of any portable power station lies in its capacity and output. Here, both DELTA Pro and DELTA Pro Ultra boast impressive figures.
The DELTA Pro offers a substantial 3.6kWh battery
This makes it capable of powering essential devices and appliances for extended period.
Some examples include:
- Laptops: A typical laptop consumes around 60 watts and lasts for 6 hours on battery. With 3.6kWh, you could power a laptop for up to 60 hours.
- Smartphones: With a mere 5 watts and 10 hours of battery life, a smartphone could run for up to 720 hours on 3.6kWh.
- Televisions: A 150-watt television lasting 3 hours on a charge could be powered for up to 24 hours with 3.6kWh.
- Refrigerators: While a refrigerator uses around 100 watts continuously, it cycles on and off throughout the day. Assuming 24 hours of typical usage, you could power a refrigerator for up to 36 hours with 3.6kWh.
- Washing machines: These appliances are power hungry, consuming around 1800 watts for a 1.5-hour cycle. You could run a washing machine for up to 2 cycles with 3.6kWh.
The DELTA Pro Ultra ups the ante with a colossal 6kWh capacity
This nearly doubles the available power from the DELTA Pro, and it translates to powering your entire home during outages, running heavy appliances with ease, and keeping the adventure fueled for longer.
The DELTA Pro Ultra can also power:
- Laptops: With a typical power consumption of 60 watts and a 6-hour battery life, you could power a laptop for up to 100 hours on 6kWh of energy. That's over four full days of uninterrupted work or entertainment!
- Smartphones: At 5 watts and 10 hours of battery life, a smartphone could run for up to 1200 hours on 6kWh. That's practically two months of continuous phone usage!
- Televisions: A 150-watt television lasting 3 hours on a charge could be powered for up to 40 hours with 6kWh. That's enough for nearly two full days of movie marathons or binge-watching your favorite shows.
- Refrigerators: Assuming 24 hours of typical usage, you could power a refrigerator for up to 60 hours with 6kWh. That's two and a half days of keeping your food fresh without power from the grid.
- Washing machines: You could run a washing machine for up to 3 cycles with 6kWh of power.
- Electric cars: While not for charging to full, you could add a significant amount of range to an electric car with 6kWh. Assuming a typical consumption of 10,000 watts per hour, you could get up to 0.6 hours of driving time.
This isn't the only arena where the DELTA Pro Ultra shines brighter. The DELTA Pro Ultra AC output reaches a staggering 7200W, compared to the DELTA Pro's 3600W.
From running power tools and air conditioners to keeping refrigerators humming and entertainment centers pulsating, the DELTA Pro Ultra flexes its muscles as a true whole-home backup solution.
DELTA Pro vs DELTA Pro Ultra Output Ports
The output ports for both power stations are fairly similar, but we'll put them side-by-side below so you can compare for yourself.

DELTA Pro vs DELTA Pro Ultra Charging Speed
Replenishing power reserves is crucial, and both DELTA Pros handle it with admirable efficiency.
The DELTA Pro accepts a maximum AC charging input of 1800W while the DELTA Pro ultra accepts 3000W

At 1800W AC input, the DELTA Pro can be fully recharged from 0% to 100% in an estimated 1 hour and 45 minutes using AC power.
However, at 3000W AC input, the DELTA Pro Ultra can be fully recharged from 0% to 100% in an estimated 1 hour and 13 minutes using AC power.
But also remember that the DELTA Pro Ultra battery is larger and yet it still recharges at a faster rate. Impressive!
Ultimately, using EcoFlow's proprietary X-stream charging technology, which they claim works by safely increasing the voltage - therefore boosting the electric flow - both batteries recharge at remarkable speeds relative to any other power station on the market.
The DELTA Pro also accepts a maximum of 1600W of solar input while the DELTA Pro Ultra accepts a maximum of 5600W

This equates to approximately 3-6 hours to charge depending on the amount of sunlight available and the solar panel output.
The DELTA Pro Ultra, however, smashes charging speed records with a mind-blowing 5600W input between two solar inputs:
High voltage PV input: 80-450V, 15A, 4000W Max
Low voltage PV input: 30-150V, 15A, 1600W Max.
This translates to a mere 1.1 hours for a complete refill, minimizing downtime and maximizing uptime for your adventures.
DELTA Pro vs DELTA Pro Ultra Expandability
EcoFlow DELTA Pro Expandability
Until recently, the EcoFlow DELTA Pro was the king of the portable power station market when it comes to expandability.
With the DELTA Pro, you can double your 3.6kWh capacity to 7.2kWh buy adding a smart extra battery and achieve 10.8 kWh with two smart extra batteries.
Further, you can get all the way up to 21.6kWh by connecting two DELTA Pros with the Double Voltage Hub and get all the way up to a monster 25kWh by adding two EcoFlow Dual Fuel Smart Generators.
It couldn't possibly get better than that, right?
It can.
EcoFlow DELTA Pro Ultra Expandability
When you stack five smart extra batteries with the brand-new DELTA Pro Ultra you can achieve a ridiculous 30kWh of off-grid power.
But there's more!
Connect three inverter stacks with the Smart Home Panel 2 and you can scale up to 90kWh of capacity.
DELTA Pro vs DELTA Pro Ultra Wi-Fi and Bluetooth Connectivity

However, the DELTA Pro Ultra boasts an additional ace up its sleeve: a dedicated 4G LTE modem port. This opens a world of possibilities, letting you access and manage your power station even in remote areas with weak Wi-Fi signals.
Imagine the peace of mind knowing you can check on your home's power situation from anywhere!
DELTA Pro vs DELTA Pro Ultra Portability and Ruggedness

Portability considerations come into play for the on-the-go adventurer. The DELTA Pro, weighing in at 99 lbs., remains a formidable yet portable powerhouse.
The DELTA Pro Ultra, however, tips the scales at a heftier 189 lbs. (72 lbs. for the inverter and 116 lbs. for the battery).
While still manageable with its built-in wheels, its size might necessitate vehicle transportation for longer treks.
DELTA Pro vs DELTA Pro Ultra: Which is Better?
So, which DELTA reigns supreme? The answer lies not in a singular victor, but in your unique needs and aspirations.
The DELTA Pro remains a formidable force, ideal for off-grid enthusiasts and those seeking a powerful short-term home backup solution.
The DELTA Pro Ultra, however, pushes the boundaries of portable power, becoming a true whole-home hero and a champion for extended adventures.
Truthfully, the DELTA Pro Ultra exceeds its predecessor in nearly every specification.
There are, however, a couple of things that may make the DELTA Pro more attractive than the DELTA Pro Ultra
- The price point for the DELTA Pro Ultra, while not yet announced at the publication of this article, will certainly be higher than the DELTA Pro. So, if price is a factor for you, then you will want to take that into consideration.
- The combined battery and inverter weight of the DELTA Pro Ultra far exceed the weight of the DELTA Pro by 90 lbs. Sure, you can wheel both of them around with the retractable lever and wheels, but the heft of the newer device may be something you want to take into consideration. If you're just setting it up to serve as a home backup solution, then you'll probably be fine. If you are planning long-term off-grid adventures, it may be more of a chore to move around.
Ultimately, the choice between these titans comes down to your power appetite, budget, and lifestyle. Whether you're a weekend warrior seeking weekend escapades or a guardian of home and hearth, EcoFlow's DELTA Pro series has a champion waiting to unleash its power within you.
