Power stations
Jackery vs EcoFlow vs Bluetti vs Anker 1000Wh Power Stations
Start with the EcoFlow Delta 3 Classic if you have no special requirement. It has the 1,800W continuous output most of this class shares, the joint-highest 3,600W surge, a UPS switchover under 10 milliseconds and six AC outlets, at 26.7 pounds. It cannot take an extra battery, so pick a different unit if growth, weight or solar input comes first.
- Best for: home backup of a fridge, router and everyday electronics.
- Why: the joint-strongest surge and fastest switchover rating here, plus 45 minutes to 80 percent from the wall.
- Skip if: you carry it often (Jackery Explorer 1000 v2, 23.8 lb), want to add batteries (EcoFlow Delta 3, up to 5kWh) or want 600W of solar input (Anker SOLIX C1000).
Updated October 9, 2026
Five current power stations sit in the 1kWh class, and on paper they look almost interchangeable, with 1,024 to 1,152Wh and 1,500 to 1,800W of output each. The differences that matter are weight, surge, switchover speed and whether you can add a battery later. Below, the five are lined up side by side, followed by a verdict for each head-to-head question readers ask most.
Research-based comparison. We checked each model against its manufacturer's published specifications on September 29, 2026. We have not hands-on tested these units, so nothing here is a measured runtime, noise or durability result. See how we research and pick gear.

Which one fits your situation
- You carry it a lot for camping, car trips or moving it room to room: the Jackery Explorer 1000 v2. At 23.8 pounds it is the lightest here by almost three pounds. You give up 300W of continuous output, half the AC outlets of the Anker and EcoFlow units, and any way to add a battery.
- Home backup for a fridge, router and electronics: the EcoFlow Delta 3 Classic or Delta 3. Both switch to battery in under 10 milliseconds and carry a 3,600W surge rating for compressor starts.
- You may want more capacity later: the EcoFlow Delta 3, which expands to 5kWh, or the Anker SOLIX C1000, which takes one 1,056Wh expansion battery for 2,112Wh.
- Solar is your main charger in a van, cabin or on long trips: the Anker SOLIX C1000, with the highest solar input here at 600W.
- The most energy in one box, and it mostly stays put: the Bluetti AC180 at 1,152Wh. It is also the heaviest at 35.3 pounds.
- You already own a DELTA 2 extra battery: the EcoFlow Delta 3, which EcoFlow lists as compatible with it. The Delta 3 Classic is not.
Some readers should skip this class. If you only need phones, lights and a CPAP for a night or two, a 300Wh-class unit from our budget picks is a smaller, cheaper buy. If you need a fridge, a freezer and a well pump through multi-day outages, 1kWh is too small; a 3kWh unit like the one in our Anker SOLIX F3000 review is the right starting point.
The five models side by side
The Delta 2 appears as a reference row only. It is no longer a current Amazon buy, so it has no shopping link.

Highlighted cells lead their column. † marks a figure our older comparison pages stated differently, or where a maker's own pages disagree; each one is explained under Sources and the table uses the manufacturer's spec sheet. Surge is a momentary rating for motor and compressor starts, not extra continuous power.
Head-to-head
The matchups readers ask about
Each pairing leads with the verdict. Where a question involved the Delta 2, the current answer uses the Delta 3 Classic, its like-for-like replacement, and keeps the Delta 2 as a reference point.
Jackery Explorer 1000 v2 vs Bluetti AC180
Verdict: buy the Jackery if you will carry it, and the AC180 if it will mostly sit at home. The Jackery is 11.5 pounds lighter; the AC180 adds 82Wh, 300W more continuous output and a fourth AC outlet.
- Output: the AC180 runs 1,800W continuously against 1,500W, so a 1,500W kettle or hair dryer leaves it more headroom. The Jackery has the higher surge rating, 3,000W against 2,700W, which helps with motor starts.
- Charging: close. The AC180 reaches 80 percent in 45 minutes in Turbo mode, and the Jackery reaches full in about an hour in Emergency Charge mode.
- Solar and growth: the AC180 takes 500W of solar against 400W, and Bluetti lists add-on battery packs that connect through its DC input. The Jackery has no expansion option.
- Battery rating: both are LiFePO4, rated for 3,500-plus cycles on the AC180 and 4,000 cycles to 70 percent on the Jackery.
Jackery Explorer 1000 v2 Bluetti AC180
Anker SOLIX C1000 vs Jackery Explorer 1000 v2
Verdict: the C1000 is the more capable unit and the Jackery is the easier one to carry. Choose the C1000 for 1,800W of output, six AC outlets, 600W of solar input and an expansion battery. Choose the Jackery to save 4.6 pounds.
- Output and surge: 1,800W against 1,500W continuous, but the Jackery's surge rating is higher, 3,000W against 2,400W. Anker's SurgePad mode is meant for heating appliances, and Anker says it does not support precision instruments.
- Charging: effectively a tie in the fast modes, 58 minutes in Anker's UltraFast mode against about an hour in Jackery's Emergency Charge mode. Both are switched on in the app.
- Growth: the C1000 accepts one Anker BP1000 battery (1,056Wh) for 2,112Wh in total. The Jackery cannot expand.
- Ports and switchover: both have a 100W and a 30W USB-C port, and both list about 20 milliseconds of backup switching. Their cycle ratings use different end points, 3,000 cycles to 80 percent on the Anker and 4,000 to 70 percent on the Jackery, so they are not directly comparable.
Anker SOLIX C1000 Jackery Explorer 1000 v2
Bluetti AC180 vs EcoFlow Delta 2 and Delta 3 Classic
Verdict: the Delta 3 Classic suits most buyers. It is 8.6 pounds lighter, carries a 3,600W surge rating against 2,700W, switches in under 10 milliseconds against 20, and has six AC outlets against four. Choose the AC180 if you want 128Wh more capacity or a way to add a Bluetti battery pack later.
- What they share: 1,800W continuous output, 500W of solar input and 45 minutes to 80 percent from the wall.
- The original matchup: charging was close, with the AC180 reaching 80 percent in 45 minutes and the Delta 2 in 50. The Delta 2's real edges were two more AC outlets and an extra-battery port, while the AC180 won on capacity. The Delta 3 Classic dropped that port, so if expansion matters within EcoFlow, compare the Delta 3 instead.
- AC180 expansion: there is no dedicated battery port. Bluetti lists its B80, B230 and B300 packs as add-on storage, connected by cable through the DC input, for up to 4,224Wh.
Bluetti AC180 EcoFlow Delta 3 Classic
EcoFlow Delta 2 and Delta 3 Classic vs Jackery Explorer 1000 v2
Verdict: the Delta 3 Classic for backup and heavier loads, the Jackery for carrying. The Classic has 300W more continuous output, a 3,600W surge rating against 3,000W, switchover under 10 milliseconds against under 20, six AC outlets against three and 500W of solar against 400W. The Jackery is 2.9 pounds lighter, holds 46Wh more and publishes a 4,000-cycle rating.
- Growth: neither can add a battery. If you want an EcoFlow you can expand, the Delta 3 weighs 0.9 pounds more than the Classic and grows to 5kWh.
- The original matchup: the Delta 2 had more continuous output and faster standard charging, full in 80 minutes against the Jackery's 1.58 hours (about an hour in Emergency Charge mode), while the Jackery had the higher surge rating, 3,000W against 2,700W, and weighed about 3 pounds less. The Delta 3 Classic keeps the Delta 2's output edge and removes the surge gap.
EcoFlow Delta 3 Classic Jackery Explorer 1000 v2
EcoFlow Delta 3 vs Delta 3 Classic vs Delta 2
All three hold 1,024Wh, deliver 1,800W continuously, accept 500W of solar and use LiFePO4 cells, so runtime on a given load is effectively the same. The generations differ in charging, surge, switchover and what they can connect to.
Verdict: buy the Delta 3 if you might ever add a battery or already own a DELTA 2 extra battery. Buy the Delta 3 Classic if 1kWh is enough for good. If you own a working Delta 2, nothing here forces an upgrade.
- Charging: the Delta 3 charges at 1,500W to full in 56 minutes. The Classic charges at 1,400W to 80 percent in 45 minutes. The Delta 2 reaches 80 percent in 50 minutes and full in 80.
- Surge and X-Boost: both Delta 3 models are rated for a 3,600W surge against the Delta 2's 2,700W. X-Boost runs high-wattage appliances such as heaters and kettles rated up to 2,200W on the Delta 3 and Delta 2, and up to 2,600W on the Classic.
- Switchover: both Delta 3 models are rated under 10 milliseconds. EcoFlow's current Delta 2 page describes its EPS mode as almost instant without giving a figure.
- Expansion: the Delta 3 grows to 5kWh with DELTA 3, DELTA Pro 3, DELTA 2 or DELTA 2 Max extra batteries. The Classic takes none. The Delta 2 takes one DELTA 2 or DELTA Max extra battery, up to 3,040Wh.
- Cycles and noise: the Delta 3 is rated for 4,000 cycles to 80 percent against the Delta 2's 3,000, and EcoFlow lists it under 30dB at 600W and under 40dB at 1,200W. EcoFlow publishes neither figure for the Classic.
One naming trap: EcoFlow also sells a Delta 3 Plus and larger Delta 3 models. This page covers the Delta 3 and Delta 3 Classic listings linked here, so match the exact model name on any offer.

Who the Jackery Explorer 1000 v2 suits
This section replaces our earlier Jackery Explorer 1000 v2 research review. It is based on Jackery's published specifications; it is not a hands-on test.
The Explorer 1000 v2 suits a first-time buyer who wants a light, simple 1kWh station for camping, car trips and short outages. At 23.8 pounds it is the lightest unit here. Its 1,070Wh battery puts roughly 900Wh at the outlet after inverter losses, which covers about three nights of a 30W CPAP or around 15 hours of a fridge averaging 60W. Run your own loads through the Run-Time Calculator before you rely on those rough figures.
Know its limits before you buy. Continuous output is 1,500W, the lowest here, and it has three AC outlets. Solar input tops out at 400W, it cannot take an extra battery, and Jackery lists about 12 hours to charge from a car outlet. The one-hour Emergency Charge mode is switched on in the app; standard wall charging takes 1.58 hours. Jackery lists a 3 + 2 year warranty and says it honors it only for purchases from its own site, Jackery-branded third-party stores or authorized sellers, so check who is selling a listing.
The accessory worth budgeting for is solar. The unit has two 8mm DC inputs that together accept up to 400W, so one 200W panel uses half that input in full sun and two fill it.

What happened to the EcoFlow Delta 2
This section replaces our earlier Delta 2 research review, which was also based on published specifications rather than a hands-on test.
The Delta 2 was a strong 1kWh all-rounder: 1,024Wh, 1,800W continuous with a 2,700W surge, 80 percent in 50 minutes from the wall, 500W of solar input, 27 pounds and 3,000 cycles to 80 percent. Our July 28 Amazon check found no current Delta 2 listing, so we no longer link to one. EcoFlow's own replacements split its strengths. The Delta 3 Classic keeps the 1,024Wh and 1,800W core, adds a rated switchover under 10 milliseconds and a higher surge rating, but drops the extra-battery port. The Delta 3 keeps the port and raises the ceiling to 5kWh.
The extra-battery facts matter most if you already own one. The Delta 2 accepts one 1,024Wh extra battery for 2,048Wh in total, or one DELTA Max Extra Battery for 3,040Wh. EcoFlow lists the DELTA 2 Extra Battery as compatible with the Delta 3, so that pack can move to a newer unit. The older DELTA Max Extra Battery is not on the Delta 3's list, and the Delta 3 Classic accepts no extra battery at all. Amazon showed the DELTA 2 Extra Battery out of stock on October 9, 2026, but EcoFlow's Amazon listing for its newer DELTA 3 Series Smart Extra Battery names the Delta 2 as compatible, and that pack adds the same 1,024Wh. If your Delta 2 still works, adding a DELTA 3 Series Smart Extra Battery doubles capacity without replacing the unit, and the pack carries over to a Delta 3 or Delta 3 Plus later.

How to choose a 1000Wh power station
Ignore the capacity race. The spread across these five is 1,024 to 1,152Wh, about 12 percent, which on a fridge averaging 60W is a little under two hours. Plan on roughly 85 percent of rated capacity reaching your devices after inverter losses, and size from your actual loads rather than the number on the box.
Separate continuous output from surge. Continuous watts decide what can run; surge decides what can start. A fridge or freezer compressor, a pump or a saw briefly pulls several times its running watts, which is where the EcoFlow units' 3,600W surge rating and the Jackery's 3,000W help. The boost modes are something else. EcoFlow X-Boost, Bluetti Power Lifting and Anker SurgePad let heating appliances such as kettles and hair dryers run above the rated output by supplying reduced power, and Anker says SurgePad does not support precision instruments. Treat them as a convenience for heating loads, not extra continuous watts.
If the station will sit under a desk or beside a network cabinet on wall power, switchover time is the spec to read. EcoFlow rates both Delta 3 models under 10 milliseconds, and the other three list about 20. That gap does not matter for lights or a fridge, but it can decide whether a desktop restarts when the grid drops.
Decide about expansion now, because you cannot add it later. The Delta 3 grows to 5kWh with EcoFlow's extra batteries, the C1000 adds one 1,056Wh battery, and the AC180 can draw on Bluetti packs through its DC input. The Jackery and the Delta 3 Classic stay at about 1kWh for life. If multi-day backup is even a possibility, an expandable unit costs less than buying a second station later.
Finally, check the listing, not only the model. Wall charging is close across all five, but Jackery's and Anker's fastest modes are switched on in their apps. Every maker lists a five-year warranty, though Jackery's depends on buying from an authorized channel and the Delta 3 Classic's final two years depend on registering the unit. Buy from the brand's own store listing where you can, and confirm the exact model name, especially among EcoFlow's Delta 3 variants.

Where these differ from our older comparison pages, marked † in the table:
- The Jackery Explorer 1000 v2's standard wall charge is listed at 1.58 hours, not the 1.7 hours we previously quoted.
- The Jackery's 3,000W surge rating is higher than the AC180's 2,700W, so our earlier claim that the AC180 had the stronger surge was wrong.
- Bluetti lists add-on B80, B230 and B300 packs for the AC180 through its DC input; we previously called it a sealed unit. Bluetti's spec table gives 35.3 pounds, while one overview paragraph says 37, and we use the spec table.
- The Anker C1000 accepts a BP1000 expansion battery, which our earlier comparison omitted.
- For the Delta 3 Classic, 3,600W is the surge rating and X-Boost covers devices up to 2,600W; the two are separate figures.
- The Delta 3's 56-minute full charge comes from its 1,500W AC input alone, and its solar input is 500W, the same as the Delta 2.
- We no longer quote a millisecond switchover for the Delta 2, because EcoFlow's current page does not publish one.
Frequently Asked Questions
Which 1000Wh power station is best for home backup?
For outage duty the EcoFlow Delta 3 Classic and Delta 3 have the edge, because EcoFlow rates both to switch to battery in under 10 milliseconds and both carry a 3,600W surge rating for starting a fridge compressor. Choose the Delta 3 if you want to add an extra battery later, up to 5kWh in total, and the Delta 3 Classic if you never will. The Bluetti AC180 holds the most energy at 1,152Wh, but it is the heaviest here at 35.3 pounds and lists a 20 millisecond switchover. Keep expectations realistic either way: about 1kWh covers a fridge, internet, lights and phones for part of a day, not a whole house for several days.
Can a 1000Wh power station run a refrigerator?
Yes. All five can start and run a typical kitchen fridge, as long as its startup surge stays under the unit's surge rating and its running draw stays under the continuous rating. Runtime is the real limit. Plan on about 85 percent of the rated capacity reaching your appliance after inverter losses, so a fridge that averages 60W across its on and off cycles runs roughly 14 to 16 hours on these units. Check your fridge's label or measure it, then put your own numbers into the Run-Time Calculator.
How many nights of CPAP will a 1000Wh power station cover?
A CPAP drawing 30W for eight hours uses 240Wh, so the roughly 870 to 980 usable watt-hours these units deliver covers about three nights. Heated humidification can double the draw, and 60W for eight hours uses 480Wh, which cuts that to under two nights. The Bluetti AC180 goes furthest on capacity and the 1,024Wh EcoFlow models go least far, but the gap is well under a night. Test a full night on your own machine before relying on it, and follow your clinician or equipment supplier's backup advice.
Which one charges fastest from the wall?
They are closer than the marketing suggests. EcoFlow lists a full charge in 56 minutes for the Delta 3 at 1,500W, Anker lists 58 minutes for the C1000 in UltraFast mode, and Jackery lists about an hour in Emergency Charge mode, while the Delta 3 Classic and Bluetti AC180 both reach 80 percent in 45 minutes. Anker and Jackery turn on their fastest modes in the app, and Jackery's standard mode takes 1.58 hours. Wall-charge speed rarely decides this class, so weigh it behind surge, weight and expansion.
Which ones can add an extra battery later?
The EcoFlow Delta 3 expands to 5kWh with EcoFlow's DELTA 3, DELTA Pro 3, DELTA 2 or DELTA 2 Max extra batteries. The Anker SOLIX C1000 accepts one BP1000 expansion battery for 2,112Wh in total. Bluetti lists its B80, B230 and B300 packs as add-on storage for the AC180, connected by cable through its DC input, for up to 4,224Wh. The Jackery Explorer 1000 v2 and the Delta 3 Classic have no expansion option, so buy them only if about 1kWh is enough for good.
Is the EcoFlow Delta 3 Classic the same as the Delta 3?
No. They share a 1,024Wh battery, 1,800W of continuous output and a 3,600W surge rating, but they are different products. The Delta 3 accepts extra batteries up to 5kWh, charges at 1,500W to full in 56 minutes and carries a published rating of 4,000 cycles to 80 percent. The Delta 3 Classic has no expansion port, charges at 1,400W to 80 percent in 45 minutes, and is about a pound lighter at 26.7 pounds. EcoFlow also sells a Delta 3 Plus, so match the exact model name on any listing before you buy.
Do these work as a UPS for a computer or router?
They can, with limits. EcoFlow rates the Delta 3 and Delta 3 Classic to switch in under 10 milliseconds, while Jackery, Bluetti and Anker list about 20 milliseconds for their units. Many routers, modems and lights ride through either gap, but some desktop power supplies and sensitive devices may restart on the longer one. None of these is a zero-transfer online UPS, so test your own equipment with the station plugged in before you depend on it.
How long will these batteries last over the years?
All five use LiFePO4 cells, but the makers rate cycle life to different end points, so compare carefully. EcoFlow rates the Delta 3 for 4,000 cycles to 80 percent, Bluetti rates the AC180 for 3,500-plus cycles, Anker rates the C1000 for 3,000 cycles to 80 percent, and Jackery rates the Explorer 1000 v2 for 4,000 cycles to 70 percent. EcoFlow does not publish a cycle count for the Delta 3 Classic and instead estimates a lifespan of about ten years. For a backup unit that sees a few dozen full cycles a year, any of these ratings is ample; if you will cycle it daily in a van or cabin, favor the Delta 3.
