Among these, BLUETTI Apex 300 is the lightest native 120/240V starting point and can grow into a much larger system. EcoFlow DELTA Pro 3 has about 48 percent more base energy, and Anker F3800 Plus about 39 percent more. Whichever you pick, begin with the exact receptacle, per-leg current and motor startup your circuit requires.

Total inverter watts count for less than native split-phase voltage, receptacle amperage and motor startup.
By the numbers
What we found across the portable power stations we compare, plus the checked facts behind each finding.
Only 4 of the 50 models checked meet every need here: “I need output that is natively 120V and 240V”, “I want to power chosen circuits in my home”, “Solar will be a real part of how I recharge”, and “My computer or router should switch to backup on its own”.
4 models fit, out of 50 checkedBLUETTI Apex 300 lists 2,764.8 Wh for battery capacity, 149% above the 1,111 Wh median.
How we countedThe count uses each product's current fit ratings for “I need output that is natively 120V and 240V”, “I want to power chosen circuits in my home”, “Solar will be a real part of how I recharge”, and “My computer or router should switch to backup on its own”. A need with no documented match is not counted.
How we calculatedThese are nominal watt-hour ratings. How much energy you get out depends on inverter losses, temperature and load. The median draws on the 50 of 50 models that publish comparable figures.

Decision guide
Before you compare battery sizes, line up voltage, receptacle, per-leg current, neutral and motor startup. A 240V label by itself doesn't prove that a station can run the pump or circuit you intend.
Native 120/240V comes from a single base unit, and it weighs about 31 pounds less than DELTA Pro 3 and about 53 pounds less than F3800 Plus. For direct USB and 12V use you need the optional DC Hub.
Nameplate energy is about 48 percent higher on EcoFlow than on Apex, and about 39 percent higher on Anker. That stretches runtime before expansion batteries come into the budget.
Inductive loads such as well pumps and compressors can demand a large burst for a moment. Look at the exact load, receptacle and per-leg limits rather than comparing total inverter watts alone.
Even a listed transfer accessory doesn't make every panel connection safe. Put neutral, grounding, interlock and transfer requirements into the installation plan you make with a qualified electrician.

|---|---|---|---|
| Estimated runtime | 4.7 hours | 6.5 hours | 7.0 hours |
What it tells youAnker and EcoFlow give longer base runtime, and Apex is easier to move.
Watch out forA qualified electrician should confirm the receptacles, per-leg current, neutral, grounding, transfer hardware and motor startup.
3 options
BLUETTI, Apex 300
This modular 2,764.8Wh station has native 120/240V output and 3,840W of power, and it can grow from a portable box into a multi-unit home system.
Top pick ifThe most flexible way to start with 120/240V in a single box
The base unit has no direct USB or 12V outputs. If you want portable DC use, you need the optional DC Hub.
Anker SOLIX, F3800 Plus
This 3,840Wh native-120/240V system comes with dual high-voltage solar inputs, RV outlets and a sizable ecosystem for home expansion.
Pick this instead ifIt is the pick when direct RV outlets, 3,200W of solar input and more base energy suit the installation better.
Weighing 136.7 pounds, it requires wheels and a location chosen in advance for installation. Getting it into a vehicle takes two people.
EcoFlow, DELTA Pro 3
This refined, wheeled 4,096Wh station provides 4,000W output and native 120/240V, and it works with a wide range of batteries, panels and generators.
Pick this instead ifIt is the pick for more base energy and a polished home-integration ecosystem, once the exact circuit hardware is confirmed.
Weighing roughly 115 pounds, it is a wheeled home system rather than something to carry casually. Most circuit-level automation also needs additional EcoFlow hardware.
