Quick verdict: for home backup, the EcoFlow DELTA 3 Plus is the stronger choice: more output, twice the AC outlets, faster UPS switching, 2.5 times the solar input and a battery you can expand to 5 kWh. For camping, travel and simplicity, the Jackery Explorer 1000 v2 wins: it’s about 4 lb lighter and holds slightly more energy. Both use long-life LiFePO4 batteries and recharge from the wall in about an hour.

Runtime: practically a tie
| Device | EcoFlow DELTA 3 Plus | Jackery Explorer 1000 v2 |
|---|---|---|
| Average refrigerator | ~12 hours | ~12.5 hours |
| Fridge + Wi-Fi + lamp + phones | ~9 hours | ~9.5 hours |
| CPAP, humidifier off | ~2.7 nights | ~2.8 nights |
| CPAP, humidifier on | ~1.7 nights | ~1.75 nights |
| Wi-Fi router and modem | ~35 hours | ~36 hours |
| Laptop (via AC) | ~14–15 hours | ~15 hours |
| 50-inch LED TV | ~8 hours | ~8 hours |
| 1,500 W space heater | ~35 minutes | Not recommended (at its output limit) |
The Jackery’s 4% extra capacity is worth about half an hour of fridge time, which you won’t notice in practice. Capacity is not a reason to pick one over the other; output, charging and expandability are.
Output and ports: EcoFlow runs more at once
The DELTA 3 Plus has 1,800 W and six AC outlets; the Explorer 1000 v2 has 1,500 W and three. During an outage, that’s the difference between plugging in the fridge, router, lamp, fan and a phone charger directly, or reaching for a power strip. EcoFlow also has two 140 W USB-C ports versus Jackery’s 100 W and 30 W, better for charging two laptops at once. Both surge ratings comfortably start a refrigerator.
Charging: tied on the wall, EcoFlow on solar and car
From a wall outlet, both refill in about an hour when you use their fastest mode. The gap opens elsewhere:
- Solar: EcoFlow accepts up to 1,000 W versus 400 W. With real-world losses, that’s roughly 1.5 hours of strong sun for a full EcoFlow versus three to four hours for the Jackery. See how many solar panels you need.
- Car: EcoFlow’s optional 800 W alternator charger fills it in about 1.3 hours of driving; the Jackery takes about 12 hours from a standard 12 V socket.
Home backup features: EcoFlow’s advantage
- UPS switchover: under 10 ms for EcoFlow versus 20 ms or less for Jackery. Both are fast enough for most home electronics; for a desktop computer or a CPAP left plugged in overnight, the faster switchover gives more margin.
- Expandability: EcoFlow lets you add extra batteries up to 5 kWh; the Explorer 1000 v2 is fixed-capacity.
- Smart features: EcoFlow’s app adds storm warning alerts and time-of-use scheduling; Jackery’s app lets you choose between Emergency, standard and quiet charging modes.
Portability: Jackery’s advantage
At 23.8 lb and a more compact footprint, the Explorer 1000 v2 is about 4 lb lighter than the DELTA 3 Plus, with a folding handle. If you’ll carry it to a campsite, load it into a car every weekend or have a family member who needs to move it, that’s a real benefit.

Frequently asked questions
Is EcoFlow or Jackery more reliable?
Both are established brands with LiFePO4 batteries rated for 4,000 cycles and multi-year warranties. Note that EcoFlow’s rating is to 80% remaining capacity and Jackery’s is to 70%, a looser standard. The bigger factor is how you store the unit: keep it partly charged and top it up every few months.
Can either one run a refrigerator?
Yes. Both have enough output and surge for a typical full-size refrigerator and run an average one for about 12 hours.
Do both work with a CPAP?
Yes. Both have pure sine wave AC output, a 12 V car outlet for a CPAP DC converter and quiet operation. Expect about 1.7 nights with the humidifier on. See our best power stations for CPAP.
Can I use Jackery solar panels with EcoFlow, or the other way around?
Often yes, with the right adapter cable, as long as the panels’ voltage stays within the power station’s input range. Follow our solar charging guide.
The bottom line
Choose the EcoFlow DELTA 3 Plus for home backup: more output, more outlets, faster UPS, much stronger solar charging and room to expand. Choose the Jackery Explorer 1000 v2 if you’ll carry it often and want the simplest, lightest 1 kWh box.
