How we picked
We scored all 17 current stations of 1,500 Wh or more in our power station database using our published rubric, which weighs chemistry and rated cycle life, continuous output, energy per pound, recharge speed, expandability, UPS switchover, warranty and app control. Two models tie at the top: the DJI Power 2000 and the DELTA Pro 3. We named the DELTA Pro 3 best overall because its double capacity, higher inverter rating and published 8,000 W surge match a home-backup job better. Every other label states its filter.

Best overall
EcoFlow DELTA Pro 3
- Battery chemistry
- LiFePO4
- Rated cycle life
- 4,000
- AC output
- 4,000 W
- Energy density
- 36.09 Wh/lb
A 4096Wh LiFePO4 wheeled power station with 4000W of 120/240V output and a 10 ms UPS, aimed at whole-circuit home backup that can expand to 12kWh per unit with extra batteries.
Strengths
- 120V and 240V output, including NEMA TT-30R, 6-20R and L14-30R outlets
- 2600W of solar input across high-PV (30-150V) and low-PV (11-60V) ports
- Expandable to 12kWh with two DELTA Pro 3 extra batteries
- LiFePO4 battery rated for 4,000 cycles to 80% capacity
Watch out for
- Weighs 113.5 lb
- No cigarette-lighter socket; 12V output is via an Anderson port and DC5521
- Not compatible with original DELTA Pro or DELTA Pro Ultra accessories
The DELTA Pro 3 is built for the outage that lasts longer than an evening. Its 4,096 Wh pack keeps an ENERGY STAR fridge, an efficient furnace fan, a router and a modem running for about 31 hours. Its 4,000 W inverter and 8,000 W surge start a 1/2 HP sump pump with 5,000 W of surge headroom to spare, and its 120 V and 240 V outlets include a NEMA L14-30R for a transfer-switch connection. Solar input reaches 2,600 W across a high-voltage (30-150 V) and a low-voltage (11-60 V) port, and two extra batteries take it to 12 kWh.
The cost is mass. At 113.5 lb it’s wheeled, not carried. There’s no cigarette-lighter socket (12 V comes from an Anderson port), and EcoFlow says it doesn’t work with original DELTA Pro or DELTA Pro Ultra accessories. All fields are on the DELTA Pro 3 spec page.
Best under 50 lb
DJI Power 2000
- Battery chemistry
- LiFePO4
- Rated cycle life
- 4,000
- AC output
- 3,000 W
- Energy density
- 42.23 Wh/lb
A 2,048Wh LFP power station with 3,000W output, four AC outlets, four USB-C ports and expansion to 22,528Wh, aimed at home backup and power-hungry outdoor setups.
Strengths
- Expands to 22,528Wh with up to 10 Expansion Battery 2000 units
- Four USB-C (two 140W, two 65W) and four USB-A ports
- Over 80% capacity after 4,000 cycles
- UPS switchover within 0.01 seconds; Wi-Fi/Bluetooth DJI Home app control
Watch out for
- Weighs about 22 kg (48.5 lb)
- Solar (up to 1,800W) and 1,000W car charging need optional SDC chargers
- DJI states 0-80% AC recharge in 55 minutes but no 0-100% time
- No built-in 12V car socket
The Power 2000 shares the top score and is the highest-rated home-backup station under 50 lb. At 48.5 lb it carries 2,048 Wh, a 3,000 W inverter, a 10 ms UPS and four USB-C ports (two 140 W). Its expansion ceiling is the third-highest we track: up to ten 2,048 Wh batteries for 22,528 Wh.
DJI doesn’t publish a surge rating, so plan on its 3,000 W continuous figure as the start-up limit. That’s exactly enough for a 1/2 HP sump pump alone, but not with a fridge running at the same time (that combination peaks near 3,200 W). Solar and 1,000 W car charging both need DJI’s optional SDC chargers, and DJI quotes 0-80% AC charging in 55 minutes without a full-charge time.
Longest cycle rating (6,000)
BLUETTI Apex 300
- Battery chemistry
- LiFePO4
- Rated cycle life
- 6,000
- AC output
- 3,840 W
- Energy density
- 33 Wh/lb
A 2,764.8Wh LiFePO4 home battery backup unit with a 3,840W 120/240V inverter, NEMA 14-50R and TT-30R outlets, and support for up to six expansion batteries, aimed at whole-circuit home and RV backup.
Strengths
- Expandable with up to 6 B300K/B300S/B300 batteries per unit.
- Four 20A outlets plus NEMA TT-30R and NEMA 14-50R (120/240V).
- Dual 1,200W XT60 solar inputs (2,400W total, 12-60V).
- 3,840W Turbo charging reaches 80% in 45 minutes.
Watch out for
- No built-in USB or 12V ports; these require the separate Hub D1.
- 83.78 lb before adding batteries.
- 0ms UPS switchover needs the 240V setting and specific outlets; at 120V it is 20ms.
- Standard 15A AC charging port is limited to 1,800W.
The Apex 300 is rated for 6,000 cycles to 80%, 50% more than most rivals. Daily cycling for solar self-consumption, rather than occasional outage use, is where that pays off. It pairs 2,764.8 Wh with a 3,840 W 120/240 V inverter, NEMA 14-50R and TT-30R outlets, 2,400 W of solar across two 12-60 V XT60 inputs and 3,840 W Turbo charging that reaches 80% in 45 minutes. It takes up to six expansion batteries.
Read the fine print. There are no USB or 12 V ports without the separate Hub D1, its 0 ms switchover needs the 240 V setting and specific outlets (it’s 20 ms at 120 V), and BLUETTI doesn’t publish a surge figure.
Most capacity and output
Jackery Explorer 5000 Plus
- Battery chemistry
- LiFePO4
- AC output
- 7,200 W
- Energy density
- 37.47 Wh/lb
- Solar recharge rate
- 0.79 W per Wh
A 5,040Wh LiFePO4 home-backup power station with 7,200W of 120V/240V output, aimed at whole-home or essential-circuit backup paired with Jackery's Smart Transfer Switch.
Strengths
- 7,200W continuous / 14,400W surge with 120V/240V NEMA L14-30R and 14-50 outlets
- Takes up to 5 Battery Pack 5000 Plus units (5,040Wh each)
- High-PV (135-450V) and dual Low-PV (16-60V) solar inputs, up to 4,000W per Jackery
- 0 ms online UPS mode on the NEMA 5-20 outlets (3,600W max)
Watch out for
- About 134.5 lb, so it is a stationary unit rather than a portable one
- Default backup UPS mode switches in 20 ms; 0 ms online mode must be enabled and limits output to 3,600W
- Cycle life is rated 4,000 cycles to 70%, not 80%
- Portable panels use the two 8mm low-PV ports (16-60V, 1,200W max); the MC4 high-PV input needs 135-450V strings
Nothing we track matches the Explorer 5000 Plus on size: 5,040 Wh per unit, 7,200 W continuous and 14,400 W surge at 120/240 V. It’s the only pick here that can start and run a 3-ton central air conditioner (5,400 W running, 7,200 W starting), for about 48 minutes. Up to five battery packs take it to 30,240 Wh, and Jackery quotes up to 4,000 W of solar.
At about 134.5 lb it’s stationary. Default UPS mode switches in 20 ms; the 0 ms online mode limits output to 3,600 W. Jackery rates cycle life to 70% capacity, not 80%, so its cycle figure isn’t directly comparable with the others.
Fastest full AC recharge, 3 kWh+
PECRON E3600LFP
- Battery chemistry
- LiFePO4
- Rated cycle life
- 3,500
- AC output
- 3,600 W
- Energy density
- 38.89 Wh/lb
A 3,072Wh LiFePO4 power station with a 3,600W 120V inverter, a TT-30R outlet and up to 2,400W solar input, expandable to 18,432Wh, aimed at home backup and RV use.
Strengths
- 3,600W rated / 7,000W peak pure sine wave inverter
- 2,400W solar input across two XT60 ports (32-150V)
- 3,200W AC input with the 30A cable, about 1.3 hours to full
- Expands to 18,432Wh with four EP3800-48V batteries
Watch out for
- Around 79 lb before expansion batteries
- With the 15A cable, AC input drops to 1,800W and UPS protection to 1,800W loads
- UPS switchover is 8-20 ms; Pecron says it is not for loads needing under 8 ms
- 240V output requires pairing two units with a separate 240V box
Among stations of 3 kWh or more that publish a full recharge time, the E3600LFP is quickest at 78 minutes, using 3,200 W of AC input through its 30 A cable. It pairs 3,072 Wh with a 3,600 W inverter (7,000 W surge), a TT-30R outlet, 2,400 W of 32-150 V solar on two XT60 ports and expansion to 18,432 Wh.
On the standard 15 A cable, AC input drops to 1,800 W and UPS protection to 1,800 W loads. The 8-20 ms switchover comes with Pecron’s own warning that it isn’t for loads needing under 8 ms, and 240 V output needs two units and a separate box. It’s about 79 lb.
How much capacity do you need for an outage?
Start with daily watt-hours, not appliance count. Here’s a realistic essentials load built from our appliance wattage table:
| Appliance | Running watts | Duty cycle | Average watts | Wh per day |
|---|---|---|---|---|
| ENERGY STAR full-size fridge | 160 W | 32% | 51.2 W | 1,229 |
| Efficient variable-speed furnace fan | 200 W | 24% | 48 W | 1,152 |
| Wi-Fi router | 6.5 W | 100% | 6.5 W | 156 |
| Cable modem | 6 W | 100% | 6 W | 144 |
| Total | 372.5 W | 111.7 W | 2,681 |
That’s 2,681 Wh at the appliances. Divide by our 85% usable-energy assumption and you need about 3,150 Wh of rated capacity per day. A 2,048 Wh station covers about 16 hours of it; the 4,096 Wh DELTA Pro 3 covers about 31 hours; the 5,040 Wh Explorer 5000 Plus about 38.
Add a ResMed AirSense 11 at its 56.1 W typical draw and four LED bulbs, run around the clock as the calculator assumes, and the average climbs to about 204 W. The DELTA Pro 3 then lasts about 17 hours. In practice you’d only run the CPAP and lights for part of the day, so the real figure lands between those two numbers. Our runtime calculator lets you set quantities and see the result for every station at once.
What you'll plug in
- Full-size refrigerator (ENERGY STAR)160 W, cycles 32% of the time
- Wi-Fi router6.5 W
- LED bulb (60 W equivalent)9 W
- Smartphone charger10 W

Which essentials can a 2kWh station keep running?
Here’s the full list against our top pick, then the 2 kWh class side by side:
| Appliance | Draw | Inverter | Runtime | Runtime as a share of 24 hours |
|---|---|---|---|---|
| Full-size refrigerator (ENERGY STAR) | 160 Wavg 51 W cycling | Runs | 2.8 days | |
| Compact chest freezer (ENERGY STAR) | 180 Wavg 56 W cycling | Runs | 2.6 days | |
| Furnace fan (efficient variable-speed motor) | 200 Wavg 48 W cycling | Runs | 3.0 days | |
| Furnace fan (standard motor) | 500 Wavg 120 W cycling | Runs | 29 h | |
| Furnace blower (1/4 HP) | 600 W1,000 W to start | Runs | 5.8 h | |
| Submersible sump pump (1/2 HP) | 1,000 W3,000 W to start | Runs | 3.5 h | |
| Well pump (typical residential) | 1,000 W2,100 W to start | Runs | 3.5 h | |
| ResMed AirSense 11 CPAP | 56 W | Runs | 2.6 days | |
| Wi-Fi router | 6.5 W | Runs | 22.3 days | |
| Microwave oven (1.25 cu ft) | 1,500 W | Runs | 2.3 h | |
| Portable space heater (high setting) | 1,500 W | Runs | 2.3 h | |
| Window air conditioner (13,000 BTU) | 1,800 W2,800 W to start | Runs | 1.9 h |
Runtime = usable energy ÷ average draw. We count 85% of the rated 4,096 Wh as usable (3,482 Wh) to cover inverter and DC conversion losses. Fridges and freezers are averaged over their compressor cycle. An appliance runs only if its running watts fit the 4,000 W inverter and its start-up surge fits the 8,000 W surge rating. Wattages come from our appliance wattage table; try your own mix in the runtime calculator.
| Load (running alone) | DJI Power 2000 (2,048 Wh) | OUPES Mega 2 (2,048 Wh) | Growatt INFINITY 2000 PRO (2,048 Wh) | DELTA Pro 3 (4,096 Wh) |
|---|---|---|---|---|
| ENERGY STAR fridge | 34 h | 34 h | 34 h | 2.8 days |
| Compact chest freezer | 31 h | 31 h | 31 h | 2.6 days |
| Variable-speed furnace fan | 36 h | 36 h | 36 h | 3.0 days |
| Standard furnace fan (500 W, cycling) | 15 h | 15 h | 15 h | 29 h |
| 1/2 HP sump pump, pumping nonstop | 1.7 h | 1.7 h | 1.7 h | 3.5 h |
| Essentials load above | 16 h | 16 h | 16 h | 31 h |
So a 2 kWh station keeps the fridge or the furnace fan going for well over a day, but not both plus internet for more than about 16 hours. That’s the honest answer for most households: a 2 kWh unit bridges an overnight outage; a 4 kWh unit or an expanded 2 kWh unit covers a full day.
About sump pumps. Our table shows pumping time if the pump ran nonstop, which it rarely does. A sump pump runs only while the pit refills. As pure arithmetic, a 1,000 W pump that runs 10 minutes in every hour averages about 167 W, so a DELTA Pro 3 would carry it for roughly 21 hours. Your own cycle depends on rainfall and groundwater. Start-up surge is the hard limit: the 1/2 HP pump in our appliance table needs about 3,000 W to start, so check the surge rating before the capacity. Our sump pump guide goes station by station.
About furnaces. A gas furnace’s blower is the electrical load. An efficient variable-speed fan averages about 48 W; a standard 500 W motor about 120 W; an older 1/4 HP blower draws 600 W while running and 1,000 W to start. Check which one you have before you size.
UPS switchover and why it matters for backup
UPS switchover is how long connected devices go without power when the grid drops and the station’s inverter takes over. Fridges, pumps and lights don’t notice 20 ms. Desktop PCs, NAS boxes, modems and some medical devices can reboot on a gap that long. Manufacturers say so themselves: Pecron warns its 8-20 ms units aren’t for loads needing under 8 ms, and Growatt states the INFINITY 2000 PRO isn’t a true UPS.
| Station | Switchover |
|---|---|
| EcoFlow DELTA Pro 3 | 10 ms |
| DJI Power 2000 | 10 ms |
| BLUETTI Apex 300 | 20 ms at 120 V (0 ms on 240 V setting, specific outlets) |
| Jackery Explorer 5000 Plus | 20 ms default (0 ms online mode, 3,600 W max) |
| PECRON E3600LFP | 8-20 ms |
| Anker SOLIX F3800 | 20 ms |
| OUPES Mega 2 | 20 ms |
If your backup plan includes a home office or networking gear, favor a 10 ms unit or enable a 0 ms mode where offered. Our rubric scores switchover from 0 to 30 ms for exactly this reason.
Expansion batteries and solar for multi-day outages
For outages longer than a day you have two levers: more stored energy and a way to refill it.
| Station | Base | Max with expansion | Solar input max | Fastest solar refill |
|---|---|---|---|---|
| Jackery Explorer 5000 Plus | 5,040 Wh | 30,240 Wh | 4,000 W | 1.3 h |
| Anker SOLIX F3800 | 3,840 Wh | 26,880 Wh | 2,400 W | 1.6 h |
| DJI Power 2000 | 2,048 Wh | 22,528 Wh | 1,800 W (optional charger) | 1.1 h |
| PECRON E3600LFP | 3,072 Wh | 18,432 Wh | 2,400 W | 1.3 h |
| EcoFlow DELTA Pro 3 | 4,096 Wh | 12,000 Wh | 2,600 W | 1.6 h |
| OUPES Mega 2 | 2,048 Wh | 10,240 Wh | 2,100 W | 1.0 h |
| Growatt INFINITY 2000 PRO | 2,048 Wh | 6,144 Wh | 1,200 W | 1.7 h |
| BLUETTI Apex 300 | 2,764.8 Wh | Up to 6 batteries | 2,400 W | 1.2 h |
“Fastest solar refill” assumes enough panels to saturate the input, at 75% of their rating. That’s a big array: hitting 2,600 W on the DELTA Pro 3 takes about 3,470 W of rated panels.
A more useful target is replacing one day of essentials. Our 2,681 Wh load means refilling about 3,150 Wh of capacity. In five hours of good sun, that’s about 630 W delivered, or roughly 840 W of rated panels: two 400 W folding panels plus a bit more. Our solar panel rankings cover which panels fit which inputs, and the solar panel matcher checks voltage limits for any pairing.
The DELTA Pro 3’s dual inputs give you room to grow: its high-voltage port accepts long series strings that low-voltage stations can’t. Here’s every panel we track checked against it:
- Solar input up to 2,600 W
- Voltage window 11–150 V
- Connector not published

Recharge time is from empty with one panel in full sun: 4,096 Wh ÷ the lower of75% of the panel's rating or the station's solar input limit. A panel rated above the input limit is safe as long as its Voc fits, because the station only draws what it can take. MC4 panels need a standard MC4 adapter cable, which many stations include. Wiring two panels in series doubles the Voc, so check the total against the voltage window. Try any pairing in the solar panel matcher.

Which home backup station should you buy?
- Most households wanting a full day of essentials: DELTA Pro 3.
- Overnight backup you can still lift into a car: DJI Power 2000, expanding later as needed.
- Daily solar cycling as well as backup: BLUETTI Apex 300 for its 6,000-cycle rating.
- Whole-home loads, including central air: Jackery Explorer 5000 Plus or Anker SOLIX F3800.
- Fast recharges between storms on a 30 A circuit: PECRON E3600LFP.

Frequently asked questions
What is the best power station for home backup?
The EcoFlow DELTA Pro 3 is our pick. It ties the DJI Power 2000 for the top score above 1,500 Wh (8.8/10), and its 4,096 Wh capacity, 4,000 W of 120/240 V output and 8,000 W surge suit whole-circuit backup better than the DJI's 2,048 Wh and 3,000 W.
How long will a power station run a refrigerator during an outage?
An ENERGY STAR fridge averages about 51 W over its compressor cycle, so a 2,048 Wh station runs it about 34 hours and a 4,096 Wh station about 2.8 days, with nothing else connected.
Can a power station run a sump pump?
Yes, if its surge rating covers the start. A 1/2 HP submersible pump needs about 3,000 W to start and 1,000 W to run. A 4,096 Wh station gives about 3.5 hours of continuous pumping, and far longer in real use because a sump pump only runs when the pit fills.
How big a power station do I need to run my house?
For essentials only (fridge, furnace fan, internet, lights), plan on about 3,000-3,500 Wh of rated capacity per day. Whole-house loads such as central air need a 6,000 W-plus inverter and drain even a 5 kWh unit in under an hour.
Does UPS switchover time matter for home backup?
It matters for computers, network gear and other electronics that reboot on a power blip. A 10 ms switchover is the safer choice for those loads; fridges and pumps don't care.
