Model comparison
The two 1 kWh units most often shopped against each other by name. The C1000 Gen 2 is the cheaper energy, 12% less per watt-hour at the makers' prices, gives 500 W more continuous output and refills from the wall in 49 minutes against 1 hour 35 minutes. Nothing on the Explorer 1000 v2's spec sheet beats it by a margin you would notice, so on the published figures the C1000 Gen 2 is the buy.

Cycle counts are highlighted only when both makers rate them to the same remaining capacity. A full recharge is not ranked against a charge to 80%. Missing figures never count as an advantage. These are manufacturer ratings; matching endpoints do not prove identical test conditions.
Rated cycles: C1000 Gen 2, 4,000 to 80%; Explorer 1000 v2, 4,000 to 70%.

Estimated AC energy = rated Wh × 0.85. Runtime = estimated AC energy ÷ load W, with no reserve. Capacity and weight differences use the displayed figures; price per Wh uses each model's own price record and date. Device-load inputs are in the sizing calculator.
Check whether each unit has enough battery and output for the devices you want to run.
| Job | Needs | C1000 Gen 2 | Explorer 1000 v2 |
|---|---|---|---|
| a day of home backup (a full-size refrigerator, a router, phones and lights for a day) | 2,323 Wh, 92 W running, 1,351 W start | no: too little capacity | no: too little capacity |
| a night of CPAP (a CPAP with its humidifier for one 8-hour night) | 599 Wh, 53 W running, 104 W start | yes | yes |
| two nights of camping (a compressor cooler, lights, phones, a laptop and a fan for two nights) | 2,066 Wh, 157 W running, 157 W start | no: too little capacity | no: too little capacity |
| a day in an RV (a 12 V fridge, lights, TV, coffee maker, phones and a laptop for a day) | 648 Wh, 156 W running, 156 W start | yes | yes |
| a working day in a van (a working day of laptop, Starlink, fridge, lights and a fan) | 2,295 Wh, 244 W running, 244 W start | no: too little capacity | no: too little capacity |
| a laptop and two phones (a laptop for six hours and two phone charges) | 396 Wh, 60 W running, 60 W start | yes | yes |
Hours = capacity × 0.85 ÷ device watts, with the draws from the device table; "start" is whether the inverter's surge clears the device.

| CPAP machine (with heated humidifier) (with humidifier) | 53 | 16.4 | yes | 17.2 | yes |

More tracked models from both brands: Anker SOLIX and Jackery. Every unit at this size: the full table. Your own devices: the sizing calculator.
Anker SOLIX C1000 Gen 2 states a 10 ms switchover, so it can sit between the wall and a fridge, router or CPAP and take over when the power cuts; no switchover figure is held for Jackery Explorer 1000 v2. Jackery Explorer 1000 v2 holds more (1,070 against 1,024). Check your appliance's start-up watts against the surge figures in the table.
C1000 Gen 2 at $0.46 per Wh against $0.52. This compares purchase price with rated capacity, not lifetime delivered energy.
A small window unit draws 500 to 1,000 W running and several times that for an instant at start; check the surge figure in the table against the air conditioner's label. Either way an afternoon of it empties a 1 kWh unit; the RV page works the rooftop version.
