Numbered notes below the table give the source location or a caveat for figures that need one; check marks mark the better figure where one can be judged; “Manufacturer does not state” means absent from that maker’s page as of its check date listed under Sources. UPS switchover is how long the outlets go dark when grid power drops.

Notes on the figures

  1. C1000, rated capacity: 1056Wh
  2. Explorer 1000 v2, rated capacity: 30.4Ah/35.2V DC (1070 Wh)
  3. C1000, continuous output: 1800W Pure Sine Wave
  4. Explorer 1000 v2, continuous output: 1500W Rated, 3000W Surge peak
  5. C1000, surge: Anker labels 2,400 W as ‘SurgePad’, a mode that raises output for resistive loads such as heaters. It is not a conventional motor-start surge rating and should not be read as one.
  6. Explorer 1000 v2, surge: 1500W Rated, 3000W Surge peak
  7. C1000, full recharge: Stated as ‘a full charge in under an hour’; 60 minutes is the upper bound, not a precise figure.
  8. Explorer 1000 v2, full recharge: Jackery’s spec table gives 1.58 hours with the AC adapter; the ‘Emergency Charge 1 Hr’ headline is a faster mode.
  9. C1000, cell chemistry: LiFePO4 (Lithium Iron Phosphate)
  10. Explorer 1000 v2, cell chemistry: Long-lasting LiFePO₄ cells ensure 10+ years (4,000 charge cycles) backed up by a 5-year warranty.
  11. C1000, cycle life: 3,000 (80% Capacity)
  12. Explorer 1000 v2, cycle life: 4000 cycles to 70%+ capacity
  13. Explorer 1000 v2, cycle life: Jackery rates 4,000 cycles to 70%+ remaining capacity. Some competitors rate to 80%; the cycle counts are not directly comparable.
  14. C1000, UPS switchover: Stated as under 20 ms; the manufacturer gives an upper bound, not a measured figure.
  15. Explorer 1000 v2, UPS switchover: Stated as under 20 milliseconds; an upper bound.
  16. C1000, expandable: Up to Max. 2112Wh Capacity with Expansion Battery (Coming soon.)
  17. C1000, expandable: The expansion battery was marked ‘coming soon’ on the product page when checked; confirm it is actually on sale before counting on it.
  18. Explorer 1000 v2, expandable: No expansion option appears on the product page; the manufacturer does not explicitly state that none exists.

  27. Explorer 1000 v2, app: Feature heading ‘Smart App Control And LCD Display’.
  28. Explorer 1000 v2, noise: Marketing feature block titled ‘Peace and Quiet’.
  29. C1000, warranty: Warranty: 5-Year Warranty
  30. Explorer 1000 v2, warranty: Jackery states 3 years standard plus a 2-year extended warranty; per our policy we count the base three years.
  31. C1000, weight: Net Weight: 28.44 lb / 12.9 kg
  32. Explorer 1000 v2, weight: Around 23.8 lbs (10.8 kg)
  33. C1000, price: Manufacturer list price when checked; a $20 code brought it to $429.99 that day.
  34. Explorer 1000 v2, price: Manufacturer’s listed price when checked; may have been a sale price.

The same specs, normalized

Cost per watt-hour $0.43/Wh ✓ $0.51/Wh
Watt-hours per pound 37.1 Wh/lb 45.0 Wh/lb ✓
Surge headroom Not comparable — the C1000 figure is a boost-mode rating, not a motor-start surge.

Rated cycle life Not comparable — rated to different remaining-capacity thresholds (80% vs 70%).
Continuous watts per dollar 4.00 W/$ ✓ 2.73 W/$

Definitions and direction of each ratio: How we verify. A recharge rate marked ≥ is computed from an upper-bound recharge time, so the true rate is at least that figure; no check mark on that row.

Calculated, not measured: hours = rated Wh × efficiency ÷ (appliance W × duty); assumptions on How we verify. “Unlikely to start”: start-up surge exceeds the stated surge rating. “Start-up not assessed” appears where the start-up draw meets or exceeds the unit’s continuous rating and the unit states no conventional motor-start surge to check it against (C1000); the hours assume the motor starts.

What the differences mean

Price per watt-hour. At the list prices we checked, the C1000 costs $0.43/Wh against $0.51/Wh for the Explorer 1000 v2. At list the C1000 is $99.01 cheaper ($449.99 vs $549) for 1,056 Wh vs 1,070 Wh. Prices move with sales; the ratio moves with them.

Weight for the capacity. The Explorer 1000 v2 carries 45.0 Wh/lb against 37.1 Wh/lb for the C1000. Both are two-hands-and-a-flat-surface units; the difference matters if the unit moves between car, porch and basement.

Output for the money. 4.00 W/$ on the C1000 against 2.73 W/$ on the Explorer 1000 v2: this is the ratio to read if your outage plan is one big appliance, not many small ones.

Which one, and for whom

On normalized measures the C1000 leads on cost per watt-hour ($0.43/Wh vs $0.51/Wh) and continuous watts per dollar (4.00 W/$ vs 2.73 W/$). The Explorer 1000 v2 answers on watt-hours per pound (45.0 Wh/lb vs 37.1 Wh/lb). The deciding figure is the one your own outage will test first:

  • CPAP overnight. Switchover: C1000 under 20 ms, Explorer 1000 v2 under 20 ms. A 40 W CPAP runs roughly 18–22 hr on the C1000 and 19–22 hr on the Explorer 1000 v2. Both makers state a 20 ms upper bound, so for one night’s CPAP the deciding figures are price and solar input.
  • Keeping a refrigerator cold. The compressor has to start before hours matter. The C1000 states a boost figure rather than a motor-start surge rating; the Explorer 1000 v2 states a 3,000 W surge rating. A full-size refrigerator needs about 900 W to start.
  • A multi-day outage with a generator or solar to recharge from. Full recharge: C1000 under 60 min, Explorer 1000 v2 95 min. The C1000 figure is an upper bound, not a measured time, so the two cannot be ranked from published numbers.

A 1,056–1,070 Wh battery cannot do what a gasoline generator does — the runtime table shows a 1,500 W space heater emptying either unit in about 0.6 hr — but it also cannot poison a household. How often gasoline generators kill indoors — and how the official count keeps being revised — is documented in our CPSC revision matrix, and this page puts every verified unit on the same refrigerator scenario.
