EcoFlow DELTA Ultra Plus maxes out at 11264Wh capacity.
If that's not enough, you've got options!
EcoFlow DELTA Pro Ultra X offers the ultimate in scalability with up to 184kWh of capacity.
That's over 60 times the capacity of DELTA Ultra Plus (standard) and Jackery Home Power 3000.
Chances are you don't need that much storage capacity, but unlike Jackery HomePower 3000, EcoFlow Delta Ultra Plus gives you room to grow without buying a new portable power station.
DELTA Pro Ultra X Whole-Home Backup Power
AC Output and X-Boost Technology
The primary power output spec for portable power stations and generators is continuous AC or DC output, typically measured in watts and kilowatts.
Fossil fuel generators sometimes use volt-amps (Va) and kilovolt-amps (kVa) because it represents a more accurate metric of actual power output after accounting for inefficiency, which is inherent in all internal combustion engine systems.
Continuous AC output is the equivalent of the metric you'd get by plugging to the grid. It measures the uninterrupted flow of electricity from a power source (except for minor undesirable variations, such as voltage drops and surges).
The rated power requirements of household appliances is typically measured in watts and kilowatts of continuous electricity output needed to operate the device.
For example, a 300W refrigerator requires 300W of electricity to run.
However, it requires significantly more wattage to start than it does to operate.
You rarely worry about starting watts vs. running watts when plugging appliances into your wall outlets.
The utility grid acts like an infinite reservoir of power. If your refrigerator compressor or air conditioner needs a massive spike of energy to start up, your home's circuit breaker usually lets that power flow without tripping, although the lights may dim briefly.
Portable power stations and solar generators are much less forgiving.
They rely on digital inverters that have hard limits. If an appliance demands even 1 watt over the generator's surge limit, the system will instantly shut down to protect its internal electronics.
This is where having sufficient surge power becomes critical. A higher surge rating provides more overhead for starting high-wattage motor and compressor driven appliances, like central AC or well pumps.
On paper, this category looks like a tie. Both the EcoFlow DELTA 3 Ultra Plus and the Jackery HomePower 3000 are rated for 3600W of continuous output and 7200W of surge power.
However, EcoFlow pulls ahead in real-world versatility thanks to its proprietary X-Boost technology.
While the Jackery has a hard limit of 3600W, the EcoFlow DELTA 3 Ultra Plus can power high-wattage resistive appliances rated up to 4600W (like heavy-duty dryers, heaters, or electric grills) by intelligently lowering the voltage and amperage to prevent the system from overloading.
With Jackery HomePower 3000 , if you exceed 3600W, the breaker trips.
EcoFlow's X-Boost provides a "soft landing" that keeps the appliance running.
UPS Switchover Speed (For Computers, Hard Drives, and Other Precision Electronics
Desktop computers, servers and hard drives depend on an uninterrupted power supply (UPS) to prevent data corruption and damage to sensitive components.
EcoFlow DELTA 3 Ultra Plus provides data center level UPS auto-switchover of 10 milliseconds (<10ms) or less.
Jackery HomePower 3000 offers <20ms auto-switching, which is more than fast enough if you're not a computer or hard drive.
10 milliseconds is barely the blink of an eye.
But that blink can make all the difference if you're concerned about data integrity and precision electronics in your home office or entertainment center.
RV and Van Life Compatibility
If you're planning on taking your power station on the road for extended RV trips or VanLife applications, you'll probably be grateful for the dedicated Anderson Powerpole output from EcoFlow DELTA 3 Ultra Plus.
This Anderson port allows you to plug your existing 12V fuse box directly into the portable power station, enabling you to run house lights, water pumps, roof fans, and other RV appliances directly.
Jackery HomePower 3000's 12V outlet is the equivalent of a "cigarette lighter" port, which are always hard-capped at 10 amps (10A) of power output.
EcoFlow’s 30A Anderson Port is rated for 30A (~378W), providing 3x the DC power output of Jackery's 10A cigarette port.
To use Jackery HomePower 3000 effectively in an RV or van with 12V lights and appliances, you must use the AC inverter built into the unit.
Battery power is always stored as direct current (DC) electricity and an inverter converts it to alternating current (AC) for household use.
DC-to-AC conversion is an inherently inefficiency (but often necessary)
process that leads to power loss.
In situations where DC-to-DC power is viable, it's 15-20% more efficient than converting DC to AC and back to DC again.
In such applications, Jackery HomePower 3000 is likely to expend 15-20% of its battery life in heat and overhead power loss.
EcoFlow DELTA 3 Ultra Plus's Anderson port eliminates the energy inefficiency of unnecessary double conversion.
Charging Methods
EcoFlow DELTA 3 Ultra Plus offers significantly more options to recharge the power station than Jackery HomePower 3000.
Charging Method Specifications
Charging Method | EcoFlow DELTA 3 Ultra Plus | Jackery HomePower 3000 |
|---|---|---|
AC Wall Charging | 1800W Max (Adjustable speed) | 1800W Max (Fixed speed) |
Solar Input Power | 1600W Max (2x 800W ports) | 1000W Max |
DC Input Voltage | 12V / 24V / 48V (Native Support) | 12V Only (24V Not Supported) |
Car Charging Speed | 12V/24V/48V (Up to 800W w/ Alternator Charger) | 12V Standard (~100W Limit) |
Generator Charging | Auto-Start/Stop (via EcoFlow Smart Generator) | Manual AC Connection Only |
More charging options means greater flexibility and energy security at home or on the road.
Solar Charging Input (PV)
If you're planning on using either EcoFlow DELTA Ultra Plus or Jackery HomePower 3000 with solar panels, the EcoFlow power station offers more solar charge input to get you fully charged faster.
For example, with 2 x 800W PV inputs (1600W total), you can connect up to 4 x EcoFlow 400W portable solar panels to the unit.
Jackery HomePower 3000 has a 1000W cap on solar charge input. Any electricity generated in excess of 1000W will be lost.
Home Wiring Integration (Manual Transfer Switch)
Jackery HomePower 3000 and EcoFlow DELTA Ultra Plus both provide the capability to connect to your home circuit board and wiring through a transfer switch.
Both units have multiple outputs built into the exterior, allowing them to power appliances and charge devices as standalone units.
However, if your primary application for the power station is home battery backup, integration with a transfer switch can be more convenient.
EcoFlow whole-home generator systems like DELTA Pro 3 and DELTA Pro Ultra X offer next-level home energy management capabilities by connecting to your home circuit board via an automatic transfer switch or EcoFlow Smart Home Panel 3.
EcoFlow DELTA 3 Ultra Plus and Jackery HomePower 3000 can only be connected to your home circuitry with a manual transfer switch.
That means that both units will sit idle while the grid is operational and must be manually engaged in a blackout.
To take advantage of EcoFlow's extensive home energy management features, upgrade to a true whole-home generator from the DELTA Pro Series or operate the portable power station as a standalone unit.
