Beyond the spec sheet
How we verify the numbers
We verify every spec and price against the brand's official product page, on a monthly price spot-check and quarterly spec audit schedule. Each figure in the tables above links to its official source with a verification date (v0.2.0, 2026-08-09), and the discrepancy table shows how we resolve conflicting claims. The arithmetic in the table below is separate: it is derived from those official specs, not hands-on tested.
What the official specs let you estimate
Each row below is calculated from official published specifications — not hands-on tested — arithmetic on the official published specifications above, using our site-wide 0.85 usable-capacity factor. Real-world runtime depends on ambient temperature, battery age and load type.
| Parameter | Jackery Explorer 1000 v2 | EcoFlow DELTA 3 | Basis |
|---|---|---|---|
| Price per Wh | $0.52/Wh | $0.61/Wh | list price ÷ rated capacity (both from brand official product page) — calculated from official published specifications — not hands-on tested |
| Estimated runtime at 53 W (CPAP with humidifier) | ≈ 17.2 h | ≈ 16.4 h | rated capacity × 0.85 usable factor ÷ 53 W — calculated from official published specifications — not hands-on tested |
| Estimated runtime at 104 W (12V fridge rated draw) | ≈ 8.7 h | ≈ 8.4 h | rated capacity × 0.85 usable factor ÷ 104 W (Dometic CFX3 55 official rated current) — calculated from official published specifications — not hands-on tested |
| Estimated runtime at 1,000 W AC load | ≈ 0.9 h | ≈ 0.9 h | rated capacity × 0.85 usable factor ÷ 1,000 W — calculated from official published specifications — not hands-on tested |
What to check yourself before buying
- Confirm the current price and any promotions on the brand's official store — list prices change between audits.
- Check the exact model's official label or datasheet: rated capacity and inverter output vary within a product line.
- Confirm warranty terms and registration requirements at checkout (terms can differ from the headline years).
- For medical devices such as CPAP, verify your unit's own label wattage and settings with your provider.
