The short version: Near-identical capacity, very different output. Anker C1000 Gen 2 has the most power at 2,000W rated and 3,000W peak. EcoFlow DELTA 3 Classic sits between at 1,800W with X-Boost to 2,600W. The Jackery Explorer 1000 v2 has the most capacity at 1,070Wh, the lightest body at 23.8 lb and the lowest price at $488.99, but the least output at 1,500W. For a camper running a fridge, lights and laptops, the output difference rarely shows up. For power tools, it does.
The numbers
- Jackery Explorer 1000 v2: 1,070Wh, 1,500W, dual 100W USB-C, full charge in about 1 hour, switchover under 20ms, 4,000 cycles, 23.8 lb, $488.99.
- Anker SOLIX C1000 Gen 2: 1,024Wh, 2,000W rated and 3,000W peak, 10 ports, full recharge in 49 minutes at 1,600W, 4,000 cycles.
- EcoFlow DELTA 3 Classic: 1,024Wh, 1,800W with 3,600W surge and X-Boost to 2,600W, 0 to 80% in 45 minutes, 10ms auto-switch, under 30dB at 600W.
Capacity is effectively a tie. Jackery's 1,070Wh is 46Wh more than the other two, which is about four minutes of a 700W kettle. Ignore it.
Where the output difference actually matters
1,500W versus 2,000W sounds decisive and usually is not. Here is what those numbers cover in a camper:
- 12V compressor fridge: 40 to 60W. Any of them, for days.
- Laptop, phones, lights, water pump: a few hundred watts. Any of them.
- 1,000W microwave: all three, briefly.
- 1,500W kettle or heater: at the Jackery's ceiling, comfortable on the other two.
- Circular saw or a big air fryer: Anker, comfortably. The others struggle or need X-Boost.
So the honest split is: if this station is for camping and backup, the Jackery does the job for less money. If it doubles as a job-site tool, buy the Anker.
Charge speed
Anker quotes a full recharge in 49 minutes at 1,600W. EcoFlow quotes 0 to 80% in 45 minutes. Jackery quotes a full charge in about an hour. These are close enough that it should not decide your purchase, and all three are fast enough to top up over a lunch stop at a hookup.
Worth noting: Anker's HyperFlash has to be enabled in the app, so out of the box you may not see the 49-minute figure.
The two Jackery variants people miss
Jackery sells three machines at roughly this size and the names hide the differences.
The HomePower 1000 v2 is 1,024Wh with 1,500W and 3,000W surge, a sub-10ms switchover and 3kV lightning protection. It is the UPS-flavoured one, better suited to sitting behind a home office.
The HomePower 1000 Plus v2 is the one to look at if the Anker's output is what attracts you: 1,800W rated and 3,600W peak, and unlike any of the others in this comparison it expands to 11kWh with five battery packs. Neither the Anker C1000 nor the EcoFlow DELTA 3 Classic expands at all.
That is the strongest argument in this size class and it is not on the Explorer 1000 v2 at all. If there is any chance you will want more capacity later, start there.
Weight
Jackery publishes 23.8 lb for both the Explorer 1000 v2 and the HomePower 1000 Plus v2, and describes the Explorer as the smallest 1kWh LFP station. If the unit is going in and out of a truck bed every weekend, a few pounds is a real consideration.
A note on prices. We quote our own Jackery prices because we keep them at or under the lowest price we can find online, and we recheck weekly. We deliberately do not quote EcoFlow or Anker prices. Both brands discount hard and run member-only and flash-sale pricing, and on the day we wrote this EcoFlow listed the same DELTA 3 Max under more than a dozen different prices at once. Check the current price yourself before you decide on cost.
FAQ
Which has the best warranty?
All three offer 5 years on their current lines. Jackery adds two extra years on purchases made through its own site, which is worth knowing when you compare against a dealer price.
Do any of these run an air conditioner?
Not meaningfully. A 13,500 BTU rooftop unit draws roughly 1,300 to 1,700W running, so even where the inverter copes, 1kWh of capacity is under an hour. Look at 3kWh and up.
Can I charge these from the truck while driving?
Yes, and it is the upgrade most people should make before buying more capacity. A DC-DC alternator charger moves about 1kWh every two hours, roughly six times what a cigarette lighter socket manages.
Which one for a van build?
If it is a permanent install, none of these. A station is a portable appliance. A van build wants a proper 12V system with a dedicated inverter and charger.
We sell Jackery and BLUETTI, not EcoFlow or Anker, so treat this as what it is: our read of the specs, written by people who sell one of the three. We have tried to be straight about where the other two win. If you want help sizing a system for your rig, talk to a parts person before you buy.
