Jackery 300 Review
294Wh of storage, 300W continuous output, Li-ion cells. Listed at $579 at Jackery.
The Jackery 300 is a portable under 600wh unit holding 294Wh. At $1.97 per watt-hour it is priced above the median for the band, so you are paying a premium over comparable capacity. Cells are Li-ion, rated for 800 cycles.

What the Jackery 300 will run, and for how long
Runtimes below are calculated from the 294Wh 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. Anything drawing more than the 300W continuous rating is left off the list because this unit cannot carry it.
| Load | Estimated runtime |
|---|---|
| Phone charge (12Wh) | 22 charges |
| Wi-Fi router (10W) | 25 hr |
| LED work light (10W) | 27 hr |
| CPAP, humidifier off (40W) | 6 hr 15 min |
| Laptop (60W) | 4 hr 10 min |
| 12V portable fridge (45W avg) | 5 hr 33 min |
| 55-inch TV (90W) | 2 hr 47 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 300 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 300 ranks 36 of 36, where 1 is the cheapest capacity in the band. That puts it in the most expensive third, so it has to earn the difference somewhere other than raw capacity. 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.
Alternatives to the Jackery 300

Who the Jackery 300 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 300 questions
How long will the Jackery 300 run a fridge?
A full-size fridge averages about 50W once you account for the compressor cycling on and off. From 294Wh, derated to 85% for inverter losses, that is roughly 5 hr on a full charge. A 12V portable fridge draws less and will run considerably longer.
Can the Jackery 300 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.
What warranty does the Jackery 300 carry?
Jackery covers it for 2 years, and rates the cells for 800 charge cycles. Cycle life and warranty are different promises, and the cycle figure is the one that tells you how long the pack stays useful.
Is the Jackery 300 worth it?
At $579 it works out at $1.97 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.
Compare this against the alternatives
Same figures, put side by side against the units people actually cross-shop it with.
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.
