Jackery 300 v2 Review
288Wh of storage, 300W continuous output, LiFePO4 cells. Listed at $359 at Jackery.
The Jackery 300 v2 is a portable under 600wh unit holding 288Wh. At $1.25 per watt-hour it is priced above the median for the band, so you are paying a premium over comparable capacity. It uses LiFePO4 cells rated for 4,000 cycles, so it is built to be kept rather than replaced. This model is discontinued, so stock is whatever is left in the channel.

What the Jackery 300 v2 will run, and for how long
Runtimes below are calculated from the 288Wh 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, though the 600W surge rating covers brief startup spikes from motors and compressors.
| Load | Estimated runtime |
|---|---|
| Phone charge (12Wh) | 22 charges |
| Wi-Fi router (10W) | 24 hr |
| LED work light (10W) | 26 hr |
| CPAP, humidifier off (40W) | 6 hr 7 min |
| Laptop (60W) | 4 hr 5 min |
| 12V portable fridge (45W avg) | 5 hr 26 min |
| 55-inch TV (90W) | 2 hr 43 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.

Where the Jackery 300 v2 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 v2 ranks 32 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.

Who the Jackery 300 v2 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 v2 questions
How long will the Jackery 300 v2 run a fridge?
A full-size fridge averages about 50W once you account for the compressor cycling on and off. From 288Wh, derated to 85% for inverter losses, that is roughly 4 hr 54 min on a full charge. A 12V portable fridge draws less and will run considerably longer.
Can the Jackery 300 v2 be charged by solar?
Jackery does not publish a maximum solar input for this model. Rather than estimate one, we leave it out. Check the manual that ships with the unit before buying panels for it.
Is the Jackery 300 v2 worth it?
At $359 it works out at $1.25 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 maximum solar input, 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.
