Quick answer
Buy the EcoFlow Delta 2 if you want the most usable power now: more continuous wattage (1,800W vs 1,500W), six AC outlets instead of three, and a faster wall recharge. It is the better home-backup and heavy-appliance pick.
Buy the Jackery Explorer 1000 v2 if weight and long-haul battery life matter more: it is about 3 pounds lighter, carries a slightly larger battery (1,070Wh), and is rated for more charge cycles. It is the friendlier camping and grab-and-go pick.
The verdict at a glance
EcoFlow Delta 2
- 1,800W continuous, so it runs more demanding appliances without X-Boost tricks
- Six AC outlets for running several things at once
- Full recharge in roughly 80 minutes on the wall
- Expandable with a bolt-on extra battery if you outgrow it
Jackery Explorer 1000 v2
- About 23.8 lb, a few pounds lighter to carry and load
- Slightly larger 1,070Wh battery for a touch more runtime
- 4,000 charge cycles, the longer-rated lifespan
- 3,000W surge headroom for brief motor start-up spikes

What the numbers actually mean
Power output: EcoFlow pulls ahead
The Delta 2 puts out 1,800W continuously versus the Jackery's 1,500W. That 300W gap is the difference between comfortably running a full-size microwave, a space heater, or a coffee maker and having to watch your load. The Jackery has the higher instantaneous surge rating (3,000W vs 2,700W), which helps a motor spin up for a second or two, but for anything you run continuously, EcoFlow's steady output is the number that matters more.
Battery and lifespan: Jackery plays the long game
Both use LiFePO4 cells, the safer and longer-lived chemistry. The Jackery holds a hair more energy (1,070 vs 1,024 Wh) and is rated for 4,000 cycles versus EcoFlow's 3,000. In plain terms, if you cycle the pack most days, both will outlast a decade of normal use, but the Jackery has more headroom on paper before its capacity fades.
Charging: EcoFlow is the speed champ
The Delta 2 refills to 80% in about 50 minutes and to full in roughly 80 minutes straight from the wall. The Jackery takes about 1.7 hours normally, or close to an hour if you switch on its emergency fast-charge mode in the app. When a storm is bearing down and you want a topped-off battery fast, EcoFlow wins this one.
Portability: Jackery is the easier carry
At 23.8 pounds the Jackery is noticeably lighter than the 27-pound Delta 2, and its taller, narrower shape is easier to tuck into a trunk or closet. If the unit is going to move around, camping, tailgating, moving room to room, those few pounds add up.
Which one wins each round
So which should you buy?
If this power station is going to live in a closet as your storm-and-outage insurance, get the EcoFlow Delta 2. The extra continuous wattage, the six outlets, and the fast recharge are exactly what you want when the grid drops and you need to keep a fridge, some lights, and a few devices going at once.
If it is going to travel with you, or you simply want the longest-lasting battery in the lightest package, get the Jackery Explorer 1000 v2. You give up some output and half the outlets, but you gain an easier carry and more cycles over the life of the unit.

Frequently asked questions
Is the EcoFlow Delta 2 or Jackery 1000 v2 better for home backup?
The EcoFlow Delta 2 is the better home-backup pick. It delivers 1,800W of continuous power versus the Jackery's 1,500W and has six AC outlets instead of three, so it can run more appliances at once. It also recharges to full in about 80 minutes, which matters when you are racing an incoming storm.
Which one is lighter and easier to carry?
The Jackery Explorer 1000 v2 is lighter at about 23.8 pounds, compared with 27 pounds for the EcoFlow Delta 2. Its taller, narrower shape also makes it easier to load into a trunk or store in a closet, which is why it is the more travel-friendly of the two.
Do both use LiFePO4 batteries?
Yes. Both the EcoFlow Delta 2 and the Jackery Explorer 1000 v2 use LiFePO4 (lithium iron phosphate) cells, which are safer and longer-lived than older lithium-ion packs. The Jackery is rated for 4,000 charge cycles to 70% capacity and the EcoFlow for 3,000 cycles to 80%.
Can either one run a CPAP machine overnight?
Both can. A typical CPAP draws 30 to 60 watts with the heated humidifier off, so either unit's roughly 1,000Wh battery can run one for several nights. The Jackery's slightly larger capacity gives it a small runtime edge, while both run quietly on battery, which matters in a bedroom.
Which recharges faster?
The EcoFlow Delta 2 recharges much faster. It reaches 80% in about 50 minutes and full in roughly 80 minutes from a wall outlet. The Jackery takes about 1.7 hours normally, or close to an hour if you enable its emergency fast-charge mode in the app.
