Jackery Explorer 5000 Plus begins with 5,040Wh, which is about 23 percent more energy than DELTA Pro 3 and 82 percent more than Apex 300. Using an 85 percent allowance, that comes to roughly 4.3 days at a measured 1.0 kWh daily load before recharge. EcoFlow has a smaller, more automated ecosystem. Apex is the lighter modular base.

In a long outage, expandable energy, several ways to recharge and careful load shedding count for more than raw peak power.
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 want to power chosen circuits in my home”, “I might expand battery capacity later”, “I need output that is natively 120V and 240V”, “My priority is keeping food cold”, and “My computer or router should switch to backup on its own”.
4 models fit, out of 50 checkedAt 5,040 Wh, Jackery Explorer 5000 Plus has the largest battery capacity of the comparable models.
How we countedThe count uses each product's current fit ratings for “I want to power chosen circuits in my home”, “I might expand battery capacity later”, “I need output that is natively 120V and 240V”, “My priority is keeping food cold”, 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
Start with a daily watt-hour budget. Pick the battery that covers your target days with a realistic reserve, and only then prove out the recharge path and circuit integration.
The largest battery on this shortlist comes with Jackery from the start. That cuts the hardware needed for a useful first system and gives it the clearest multi-day runtime advantage.
Write down the refrigerator, communications, lighting, pumps and medical equipment in watt-hours per day. Peak inverter power shows whether loads can start, and stored energy shows how long they can run.
Weather, fuel, input limits and available hours all affect solar, generator and grid charging. Even a large battery still hits zero without a workable refill plan.
Reaching a published maximum capacity can take several batteries, hubs or another base unit. Compare the full hardware, floor space, cable plan and cost at the capacity you really intend to own.
An example with real numbers
Before any recharge or expansion, the table applies an 85 percent usable-energy allowance.
The mathnominal watt-hours × 0.85 ÷ daily load watt-hours
| Situation | Explorer 5000 Plus | DELTA Pro 3 | Apex 300 |
|---|---|---|---|
| 1.0 kWh per day | 4.28 days | 3.48 days | 2.35 days |
| 1.5 kWh per day | 2.86 days | 2.32 days | 1.57 days |
What it tells youJackery gives you the most time before a recharge. EcoFlow and Apex make a stronger case when their ecosystem or staged expansion has a named role.
Watch out forEstimates here cover the base package only. Expansion ceilings need extra hardware, so never count them as included capacity.
3 options
Jackery, Explorer 5000 Plus
This 5,040Wh, 7,200W native-120/240V system has a zero-millisecond specified transfer path and can be expanded extensively with home batteries.
Top pick ifPowering chosen circuits in a long outage
Even on wheels, the 134.5-pound main unit is bulky. Automatic circuit backup also requires a Smart Transfer Switch that a professional installs.
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 when a smaller base, mature automation and balanced expansion matter more than the most starting energy.
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.
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.
Pick this instead ifIt is the pick when lower base weight and a high modular ceiling suit a system you plan to build in stages.
The base unit has no direct USB or 12V outputs. If you want portable DC use, you need the optional DC Hub.
