Jackery 1000: which one, whether it fits, and the rivals at 1 kWh
The Jackery 1000 name covers different generations, with different charging speeds and battery life. Start with a current LiFePO4 version for regular use, and compare its weight and solar input with the other 900–1,200 Wh units. Check the full model suffix before buying an older discounted unit.
The Explorer and HomePower names split the range by intended use rather than by capacity: the HomePower units add UPS switchover and a home-backup feature set, the Explorer is the portable. Their capacities differ by a few percent, so the columns that separate them are continuous output, surge, ports and price.
Should you buy the Explorer 1000 v2?
Buy it for:a night of CPAP (a CPAP with its humidifier for one 8-hour night); a day in an RV (a 12 V fridge, lights, TV, coffee maker, phones and a laptop for a day); a laptop and two phones (a laptop for six hours and two phone charges).
Not for:a day of home backup (too little capacity: needs 2,323 Wh and 1,351 W at start-up); two nights of camping (too little capacity: needs 2,066 Wh and 157 W at start-up); a working day in a van (too little capacity: needs 2,295 Wh and 244 W at start-up).
At $0.47 per watt-hour ($499) it is beaten on price per Wh by 2 rivals at this size, listed under "Better value" below. What it has that the number does not show: 23.8 lb, which is light for the class, and Jackery's 5-year warranty.

What 1 kWh runs
Capacity × 0.85 ÷ device watts, with the draws from the device table. On the Explorer 1000 v2 (1,070 Wh): a CPAP with heated humidifier (53 W) for about 17 hours; a full-size refrigerator (41 W average) for about 22 hours, provided the surge rating (1,500 W (3,000 surge)) covers the compressor start; a laptop charger (40 W) for about 23 hours. Put your own devices into the calculator to see which of these, and which rivals, clear them.
Better value at this size
Rivals between 900 and 1,200 Wh with a lower price per watt-hour than the Explorer 1000 v2.

At this size every current unit uses LiFePO4 and most state 3,000 to 4,000 cycles, so the columns that actually differ are continuous output (a 1,500 W inverter runs a coffee maker; an 1,800 W or 2,000 W one runs it with something else on), surge (which decides the refrigerator), maximum solar input (which decides whether a panel refills it in a day), UPS switchover (stated by some brands, not by others) and weight. Price per Wh at this size runs from $0.43 up, and the spread is wide enough that the name on the box is rarely the deciding number.
No: jackery.com no longer sells the original Explorer 1000 or the Explorer 1000 Pro new. The Explorer 1000 v2 and the HomePower 1000 units are the current 1 kWh Jackerys.
Is a Jackery 1000 enough for a refrigerator?
For a day, by arithmetic, yes: a full-size refrigerator averages well under 100 W, so 1 kWh covers roughly a day after inverter losses. What decides it is surge: the compressor's start-up draw must sit under the unit's surge rating, which the table shows.
Which Jackery 1000 is the best value?
By price per watt-hour, the one at the top of the first table when ordered that way. Value only matters once a unit fits: check capacity, continuous output and surge against your devices first.
