Verdict — Jackery Explorer 1000 v2 wins
At today's prices the Jackery Explorer 1000 v2 wins for the storm-prep buyer: $190 less for more watt-hours, and a fridge never notices the slower switchover. Buy the Delta 3 Plus if it will live under your desk as a UPS or feed off serious solar.
This is the comparison most people search by brand, so let's be precise about which boxes are actually on the shelf in 2026: EcoFlow's 1kWh-class unit is now the Delta 3 Plus (the Delta 2 is gone from the US store), and Jackery's is the Explorer 1000 v2. Both are LiFePO4, both are current, and they are priced $190 apart today — which is where the math starts.
The value math
Divide price by rated capacity and the gap is stark: $0.47 per watt-hour for the Jackery against $0.67 for the EcoFlow. The Jackery also simply holds more energy — 1,070Wh rated (~910 usable) against 1,024Wh (~870 usable). For the core storm-prep job — keep the fridge, the CPAP, and the router alive overnight — both deliver the same ~11–12 hours on our 77W household trio estimate, and the Jackery does it for less money in a lighter box.
The caveat the ledger makes visible: the Jackery's edge is partly a sale. Both units list at $799; at list price the value argument collapses to a coin flip and the EcoFlow's hardware advantages take over.
What the extra $190 actually buys
The Delta 3 Plus is the better machine on almost every spec that isn't capacity or price: twice the AC outlets (6 vs 3), an under-10ms transfer that makes it a legitimate UPS for a desktop or NAS, a 56-minute full recharge, 140W USB-C ports that fast-charge laptops, a 1,000W solar ceiling, and an expansion port that takes it to 5kWh later. The Jackery answers with none of that — its pitch is maximum stored energy per dollar in the lightest package, full stop.
Who should buy which
Buy the Explorer 1000 v2 if this battery's job is to sit charged in a closet and come out when ERCOT has a bad week. Capacity per dollar is the only stat that matters for that job, and it wins that stat outright today.
Buy the Delta 3 Plus if the unit will work between outages — as a UPS under a desk, as the hub of a small solar setup, or as the first block of a system you plan to expand. Those are real jobs the Jackery structurally can't do, and $190 is a fair price for them.
Frequently asked
- Is EcoFlow's Delta 2 still worth comparing against Jackery?
- No — EcoFlow no longer sells the Delta 2 standalone on its US store; the Delta 3 Plus is its current 1kWh-class unit. Comparisons still pitting the Delta 2 against current Jackery models are comparing against a discontinued product.
- Does the 10ms vs 20ms switchover difference matter?
- For a refrigerator, CPAP, or router: no — both ride through a sub-second gap far larger than either switchover. It matters for a desktop PC or NAS, where the under-10ms Delta 3 Plus behaves like a true UPS and is the safer choice.
- Which charges faster from solar?
- The Delta 3 Plus by a wide margin: it accepts up to 1,000W of panel input against the Explorer 1000 v2's 400W ceiling. With enough panel, the EcoFlow refills in roughly an hour of good sun; the Jackery needs the better part of a sunny day.
