Best for this need
Our pick
Jackery Explorer 5000 Plus starts with 5,040Wh, about 23 percent more energy than DELTA Pro 3 and 82 percent more than Apex 300. With an 85 percent allowance, that is roughly 4.3 days at a measured 1.0 kWh daily load before recharge. EcoFlow offers a smaller, more automated ecosystem. Apex is the lighter modular base.
Long outages reward expandable energy, multiple recharge paths and careful load shedding more than raw peak power.
What the facts say
Useful conclusions from the current portable power stations comparison, followed by the checked facts used to reach them.
Only 4 of 50 models checked match every need here: “I want to feed selected home circuits”, “I may add battery capacity later”, “I need native 120V and 240V output”, “Keeping food cold is my priority”, and “I want automatic backup for a computer or router”.
4 matching models from 50 checkedJackery Explorer 5000 Plus has the largest battery capacity in the comparable set at 5,040 Wh.
Match countThe count uses the current product-to-need assignments for “I want to feed selected home circuits”, “I may add battery capacity later”, “I need native 120V and 240V output”, “Keeping food cold is my priority”, and “I want automatic backup for a computer or router”. A need with no documented match does not count.
Calculation noteThis compares nominal watt-hour capacity. Real delivered energy depends on inverter losses, temperature and load. The median covers 50 of 50 models with comparable published figures.

What matters in practice
Build a daily watt-hour budget first. Choose the battery that covers the target days with a realistic reserve, then prove the recharge path and circuit integration.
Jackery starts with the largest battery in this shortlist. That reduces the hardware needed for a useful first system and gives it the clearest multi-day runtime advantage.
List refrigerator, communications, lighting, pumps and medical equipment in watt-hours per day. Peak inverter power tells you whether loads can start. Stored energy tells you how long they can run.
Solar, generator and grid charging depend on weather, fuel, input limits and available hours. A large battery without a workable refill plan still reaches zero.
Published maximum capacity can require several batteries, hubs or another base unit. Compare the complete hardware, floor space, cable plan and cost at the capacity you actually intend to own.
Worked example
The table uses an 85 percent usable-energy allowance before any recharge or expansion.
Formulanominal watt-hours × 0.85 ÷ daily load watt-hours
| Scenario | 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 that meansJackery buys the most time before recharge. EcoFlow and Apex make stronger cases when their ecosystem or staged expansion has a named role.
Keep in mindThese are base-package estimates. Expansion ceilings require additional hardware and should never be treated as included capacity.
3 options
Jackery, Explorer 5000 Plus
A 5,040Wh, 7,200W native-120/240V system with a zero-millisecond specified transfer path and deep home-battery expansion.
Winner whenLong-outage selected-circuit backup
The 134.5-pound main unit is bulky even on wheels, and a Smart Transfer Switch must be professionally installed for automatic circuit backup.
EcoFlow, DELTA Pro 3
A refined 4,096Wh wheeled station with 4,000W output, native 120/240V and broad battery, panel and generator integration.
Choose instead whenChoose it when a smaller base, mature automation and balanced expansion matter more than maximum starting energy.
At roughly 115 pounds it is a wheeled home system, not a casual carry, and most circuit-level automation requires additional EcoFlow hardware.
BLUETTI, Apex 300
A modular 2,764.8Wh station with native 120/240V output, 3,840W power and a path from portable box to multi-unit home system.
Choose instead whenChoose it when lower base weight and a high modular ceiling fit a system you expect to build in stages.
There are no direct USB or 12V outputs on the base unit. Portable DC use requires the optional DC Hub.
