Jackery Explorer 1000 v2 vs Jackery Explorer 300
Jackery's two most-searched sizes: the Explorer 300 for phones, lights and a laptop against the Explorer 1000 v2, for buyers deciding how much battery they need. The Explorer 1000 v2 is the cheaper energy, 47% less per watt-hour at the makers' prices, holds 776 Wh more and gives 1,200 W more continuous output. The Explorer 300 is 16.7 lb lighter: buy it for that, and the Explorer 1000 v2 for the money.

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: Explorer 1000 v2, 4,000 to 70%; Explorer 300, 800 to 80%.

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 and the day it was checked. The device draws are in the watt-hour calculator.
- Capacity: Explorer 300 minus Explorer 1000 v2 = -776.2 Wh (-72.5% of the Explorer 1000 v2 figure).
- Carry weight: Explorer 300 minus Explorer 1000 v2 = -16.7 lb (-70.2% of the Explorer 1000 v2 figure).
- Price per Wh: Explorer 300 minus Explorer 1000 v2 = 0.46 USD/Wh (88.3% of the Explorer 1000 v2 figure).
Will it run your gear?
Check whether each unit has enough battery and output for the devices you want to run.
| Use | Needs | Explorer 1000 v2 | Explorer 300 |
|---|---|---|---|
| a day of home backup (a full-size refrigerator, a router, phones and lights for a day) | 2,323 Wh, 161 W running, 1,351 W startup | 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 startup | yes | no: too little capacity |
| two nights of camping (camp lights, phones, a laptop and a fan for two nights) | 2,066 Wh, 157 W running, 157 W startup | no: too little capacity | no: too little capacity |
| a day in an RV (a day of RV lights, TV, phones and a laptop) | 648 Wh, 156 W running, 156 W startup | yes | no: too little capacity |
| a working day in a van (a working day of laptop, Starlink, lights and a fan) | 1,674 Wh, 189 W running, 189 W startup | 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 startup | yes | no: too little capacity |
Runtime by device
Hours = capacity × 0.85 ÷ device watts, with the draws from the device table; "Start" says whether the output and surge ratings cover the startup figure we use for each device (the refrigerator, 1,300 W startup allowance, from a larger 27 cu ft Whirlpool's tech sheet), so a "yes" there means likely, not certain, to start yours.
| Device | Draw W | Explorer 1000 v2 h | Start | Explorer 300 h | Start |
|---|---|---|---|---|---|
| CPAP machine (with heated humidifier) | 53 | 17.2 | yes | 4.7 | yes |
| Refrigerator (full-size, ENERGY STAR, ~18 cu ft top freezer) (average draw) | 41 | 22 | yes | 6 | no |
| Laptop (MacBook Air, charging) | 40 | 22.7 | yes | 6.2 | yes |
| Wi-Fi router | 24 | 37.9 | yes | 10.4 | yes |
| Starlink Mini (router built in) | 33 | 28 | yes | 7.7 | yes |
| TV, 50-inch LED / Crystal UHD | 89 | 10.2 | yes | 2.8 | yes |
| Space heater, 1500 W | 1,500 | 0.6 | yes | 0.2 | no |
Buy the Explorer 1000 v2 if…
- you want the most stored energy per dollar ($0.52 against $0.98 per Wh)
- you need more continuous output (1,500 W continuous and 3,000 W surge, against 300 W and 500 W)
- the longer warranty matters to you (5 years against 3 years)
- you want the extra capacity (1,070 Wh against 294 Wh)
Buy the Explorer 300 if…
- the $270 difference matters more than the specs

Questions buyers ask
Which is better for power outages, the Explorer 1000 v2 or the Explorer 300?
Jackery Explorer 1000 v2 holds more (1,070 against 294). Check your appliance's startup watts against the surge figures in the table.
Which is cheaper per watt-hour?
Explorer 1000 v2 at $0.52 per Wh against $0.98. This compares purchase price with rated capacity, not lifetime delivered energy.
Can either run a window air conditioner?
Only if the air conditioner's running watts stay under the AC output (1,500 W on the Explorer 1000 v2, 300 W on the Explorer 300) and its start fits the surge figures in the table: read both on the air conditioner's label or in its manual, and test it before you rely on it. For the hours, multiply the rated Wh by 0.85 for inverter losses and divide by the running watts. A unit whose label says 500 W, for example, would run about 1.8 hours on the Explorer 1000 v2 and about 0.5 hours on the Explorer 300 on a full charge, if its compressor ran without a break.
