Jackery Explorer 300D Review
300Wh of storage, LiFePO4 cells. Listed at $289 at Jackery.
The Jackery Explorer 300D is a portable under 600wh unit holding 300Wh. At $0.96 per watt-hour it is priced about where the rest of the band sits. It uses LiFePO4 cells rated for 4,000 cycles, so it is built to be kept rather than replaced.

What the Jackery Explorer 300D will run, and for how long
Runtimes below are calculated from the 300Wh rated capacity, derated to 85% for AC loads and 92% for USB and 12V loads to cover inverter and conversion losses. They are arithmetic, not lab measurements, but they are the same arithmetic applied to every unit we track, so the comparison holds.
| Load | Estimated runtime |
|---|---|
| Phone charge (12Wh) | 23 charges |
| Wi-Fi router (10W) | 26 hr |
| LED work light (10W) | 28 hr |
| CPAP, humidifier off (40W) | 6 hr 23 min |
| Laptop (60W) | 4 hr 15 min |
| 12V portable fridge (45W avg) | 5 hr 40 min |
| 55-inch TV (90W) | 2 hr 50 min |
Real figures land below these. A fridge cycles rather than drawing continuously, and cold weather costs a lithium pack usable capacity, so treat the table as the ceiling rather than the expectation.
Charging and power delivery
Maximum solar input is 2,000W. At 70% of that rating, which is what a fixed panel realistically delivers across a good day, a full charge from empty is roughly 13 min of usable sun.

Where the Jackery Explorer 300D sits in its band
We track 36 units in the portable under 600wh band with both a price and a published capacity. They run from $118 to $599.95, and from 128Wh to 576Wh. On cost per watt-hour the Jackery Explorer 300D ranks 21 of 36, where 1 is the cheapest capacity in the band. That is mid-table: neither the bargain of the band nor the unit you would call overpriced. Ranking on cost per watt-hour deliberately ignores build quality, port selection and warranty, so read it as one input rather than as the answer.

Who the Jackery Explorer 300D suits
It is a sensible buy for weekend camping, a CPAP overnight, phones and laptops, and keeping a router alive through a short outage. It is the wrong tool for anything with a heating element, and any attempt to run a fridge for more than a day.
Jackery Explorer 300D questions
How long will the Jackery Explorer 300D run a fridge?
A full-size fridge averages about 50W once you account for the compressor cycling on and off. From 300Wh, derated to 85% for inverter losses, that is roughly 5 hr 6 min on a full charge. A 12V portable fridge draws less and will run considerably longer.
Can the Jackery Explorer 300D be charged by solar?
Yes. It accepts up to 2,000W of solar input. Panels rarely hit their rated figure in the field, so plan on about 70% of the panel rating across a clear day.
Is the Jackery Explorer 300D worth it?
At $289 it works out at $0.96 per watt-hour. It costs more per watt-hour than the median unit in its band, so the case for it rests on the features rather than on the price. Read the comparison table above against the two closest rivals before deciding.
What is not published
Jackery does not state the continuous AC output, the warranty term for this model. We list figures rather than estimate them, so those rows stay empty until the manufacturer publishes them. If you need one of them to make the decision, ask Jackery directly and hold them to the answer.
How we assess these
Every figure on this page comes from the manufacturer, and every derived number, cost per watt-hour and estimated runtime, is calculated the same way for all 437 products we track. That is what makes the comparison meaningful: we are not scoring units against a private impression of them, we are putting published figures side by side and doing the arithmetic in public. Where a manufacturer stays quiet, we say so rather than filling the gap.
