Jackery Explorer 300 Plus: what can it run?
A 288Wh portable power station with a 300W AC inverter. It cannot start a full-size fridge, so it suits smaller loads such as a router or laptop.
Estimated AC runtime by device
Ranges use the low and high watt loads in our device data, from a full charge. They are planning estimates, not measured results for this model.
| Device | Load while running | Estimated runtime |
|---|---|---|
| Wi-Fi router | 8–20W | 9.8h–19h |
| Laptop, charging and active | 30–90W | 2.6h–7.0h |
| Full-size fridge | 150–250W · 35% duty cycle | Surge or output limit |
For the fridge, the 1,200W startup assumption exceeds this unit's 600W surge rating. Real fridge demand and cycling vary. A router may run longer from a compatible DC output, which this AC table does not model.
The specs that matter
- Battery: 288Wh LiFePO4, with an estimated 245Wh usable through AC at a moderate load, before idle draw.
- AC output: 300W continuous and 600W surge. Check the startup draw of motor loads.
- Weight: 8.2 lb.
- Cycle life: Jackery publishes no cycle figure at an 80% threshold, so this uses our LiFePO4 default of 3,000 cycles (est.). That is a battery-life estimate, not a runtime promise.
On Sep 25, 2026, Jackery listed a transfer time of 10 ms or less for its backup function. Test your actual router, PC or NAS through a mains-loss simulation before relying on it for uninterrupted operation.

Where the estimate can miss
This model has no published AC idle-draw measurement, so the calculation uses 6W (est.). Idle draw matters most for a small load such as a router. Inverter efficiency is our class default. Temperature, battery age, output mode and the actual device load can all move the result.
The stated surge rating tells you what the inverter is designed to accept. It does not measure your fridge's startup spike. For essential equipment, measure the load and run a full-duration test.
Nearest models by capacity
The closest smaller and larger models with a guide on this site. Fridge estimates use the same 150–250W load and 1,200W startup assumption as the runtime table on this page.
| Model | Rated capacity | AC output | Full-size fridge |
|---|---|---|---|
| Bluetti AC2A | 204.8Wh | 300W | Surge or output limit |
| EcoFlow RIVER 3 Plus | 286Wh | 600W | 2.6h–4.2h |
| Anker SOLIX C300 | 288Wh | 300W | Surge or output limit |
| Goal Zero Yeti 700 | 677Wh | 600W | Surge or output limit |
