Jackery Explorer 300
Entry 293Wh, 300W · Reviewed by Katie · amazon.com live, Sept 28 2026
Why it scored a 79
At $259 list (often $189-199 on sale), the Explorer 300 posts a strong 90 on Satisfaction with an Amazon's Choice badge and over 11,000 reviews at 4.6 stars, and Reliability backs that up at 88. Features lags at 66 with just 300W of continuous output, and independent lab testing suggests this successor to the Explorer 300 Plus may use NMC lithium-ion cells rather than the old model's LiFePO4 chemistry, a chemistry downgrade worth confirming before you buy.
What you're getting
- 293 Wh battery; lab testing suggests NMC lithium-ion rather than LiFePO4
- 300 W continuous AC output, 600 W surge, two pure sine wave AC outlets
- 100 W USB-C PD port plus two USB-A ports and a 12 V car port
- About 7.1-7.5 lb, light enough for one-handed carry
- 0-80% wall recharge in ~2 hrs; ~4 hrs via car, ~2.8 hrs with a 100 W solar panel
- 4,000 charge cycles to 70% capacity claimed
- 300 W ceiling rules out most kettles, hair dryers and space heaters
ViperScore breakdown
Should you buy the Jackery Explorer 300?
The Explorer 300 is Jackery's entry model: light, simple, and often on sale below $200. It's for phones, laptops, camera batteries and a night of LED lights. It ranks lower than the LiFePO4 compacts because its chemistry and output are a generation behind.
Where it earns its score
- 7.1–7.5 lb. Easy to carry.
- 300 W AC, 600 W surge; two pure-sine outlets; 100 W USB-C.
- Satisfaction 90. Owners are happy with it.
- Often $189–199. Cheap when discounted.
What to know first
- NMC, not LiFePO4. Lab tests suggest standard lithium-ion, which means fewer cycles over the years than the C300, RIVER 2 or Elite 30.
- Slow recharge. ~2 hours to 80%, versus 60–68 minutes for the LiFePO4 rivals.
- Features 66. No app, no fast USB-C input.
Our verdict
The Explorer 300 scores 79, Fair Buy. Buy it on a deep sale; at list, the Anker C300 or EcoFlow RIVER 2 is a better battery for similar money.

Questions buyers ask
Is the Jackery Explorer 300 LiFePO4?
No. Testing points to NMC lithium-ion, which has a shorter cycle life than the LiFePO4 packs in newer compact stations.
How long does the Explorer 300 last on a charge?
293 Wh: roughly 15 phone charges, 3–4 laptop charges, or a 10 W light for about a day.
Explorer 300 or Anker SOLIX C300?
The C300 for LiFePO4 longevity, faster charging and a better USB-C port. The Explorer 300 only if it's much cheaper on the day.
