Jackery 300 Plus Review

LiFePO4 cells. Listed at $399 at Jackery.

The Jackery 300 Plus is a portable 600 1,200wh unit. It uses LiFePO4 cells, so it is built to be kept rather than replaced. This model is discontinued, so stock is whatever is left in the channel.

Where the Jackery 300 Plus sits in its band

We track 83 priced units in the portable 600 1,200wh band, running from $119 to $9,199. At $399 the Jackery 300 Plus is the 20 cheapest of 83. Because Jackery does not publish a capacity for this model, we cannot rank it on cost per watt-hour, which is the measure we would normally lead with. Price position on its own tells you where it sits in the range but not whether it is good value, and those are genuinely different questions.

Alternatives to the Jackery 300 Plus

Units we track in the same band that are close enough to be genuine substitutes, matched on price. Each links to its own review.

Who the Jackery 300 Plus suits

This is an accessory rather than a standalone product, so the question is not whether it is good in isolation but whether the system you already own needs it.

Check compatibility against your specific model before ordering: within a single manufacturer, connectors and firmware requirements change between generations more often than the marketing suggests.

Jackery 300 Plus questions

Can the Jackery 300 Plus 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.

What warranty does the Jackery 300 Plus carry?

Jackery covers it for 5 years. Cycle life and warranty are different promises, and the cycle figure is the one that tells you how long the pack stays useful.

What is not published

Jackery does not state the watt-hour capacity, which is the single figure runtime depends on, the rated cycle life, the maximum solar input, the continuous AC output 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.
