Jackery Explorer 300 (LiFePO4 New Version)
Jackery Explorer 300: 292 Wh LiFePO4 (new version), 300 W rated. Runtime with Jackery's own 0.85 factor, and why to check the listing.
Which version: Not the Explorer 300 v2 (288 Wh, sold out on jackery.com), the Explorer 300D or the Explorer 300 Plus; jackery.com describes the current Explorer 300 as a 'New version' with LiFePO4 cells, while the original 2020 Explorer 300 under the same name used different cells — check the listing says LiFePO4.

Jackery sells the current Explorer 300 as a "New version" with LiFePO4 cells, under the same name and on the same product page as the original 2020 Explorer 300, which used different cells. When you buy, check that the listing says LiFePO4. It is also not the Explorer 300 v2 (sold out on jackery.com), the Explorer 300D or the Explorer 300 Plus.
What 300 W covers
Jackery gives 300 W rated output, and the FAQ says the AC side can power only devices under 300 W in total. No surge figure appears in the page text. That covers a Wi-Fi router (42 W), a laptop (65 W) or the Starlink Standard kit (100 W). A full-size refrigerator is out (360 W running), and for the compact refrigerator the 540 W start cannot be checked without a published surge figure.
Jackery prints its own formula for this model. Using the maker's published 0.85 factor, 292 Wh × 0.85 ÷ 42 W gives about 5.9 hours for the router and 292 Wh × 0.85 ÷ 100 W about 2.5 hours for the Starlink kit. The FAQ's own example uses 293 Wh, while the product bullet says 292 Wh.
The battery is rated for 4,000+ charge cycles to 70 % capacity. EcoFlow counts to 80 %, so equal counts are not equal lifetimes (how makers define cycle life).
What the page does not settle
The page gives two different warranty terms — one in a product bullet for the new version, another in the services block — so this card shows the warranty as not published. Surge, input and charge-time figures appear only in spec images, not in page text, and are not shown here. It weighs 7.5 lb and has a 120 W car port.

Frequently asked questions
Is the Jackery Explorer 300 LiFePO4?
The current "New version" is, per Jackery's page, rated for 4,000+ cycles to 70 %. The original Explorer 300 sold under the same name used different cells, so check that your listing says LiFePO4.
Can it run a CPAP?
The CPAP in our database runs at 53 W, inside 300 W, and its 104 W peak is within the 300 W rating. At its 34 W average, 292 Wh × 0.85 ÷ 34 W gives about 7.3 hours. Planning figures only — confirm with the device manufacturer before relying on a power station for this device.
What warranty does it have?
Jackery's page gives two different terms in two places (a product bullet and the services block), so we show the warranty as not published. Ask Jackery which applies to your unit.
How long does it take to charge?
Jackery's page text gives no wall or solar charge time; those figures appear only in images, so this card shows them as not published.
