Overview
A 292Wh portable power station built on LiFePO4 battery chemistry, weighing 7.5 pounds with a 300W rated output and 600W peak surge. It has 2 AC outlets, a 100W USB-C PD port, 2 USB-A ports and a 120W car port for 6 device connections. A compatible solar panel is sold separately.
- 292Wh capacity
- 300W rated output, 600W peak surge
- 4,000+ charge cycles to 70% capacity
- 80% solar charge in about 2.8 hrs with a 100W panel
Who it's for
Campers, market vendors, storm-prone households and anyone keeping phones, tablets, small speakers, CPAP machines or laptops running through an outage or a day outdoors are the fit. It is not sized to run a refrigerator or air conditioner, and owners needing that scale point to Jackery's larger 1000-series units instead. The 7.5 pound weight makes it reasonable to carry to a yard, market stall or tent rather than needing a cart.
What buyers say
From Amazon customer reviews.
Multiple long-term owners describe using the Explorer 300 for years without failure, powering telescopes overnight, backing up market-vendor card readers all day and getting a household through multi-day storm outages. Reviewers consistently praise its light weight relative to its capacity and its quick wall or car charging. The clearest complaint, from an owner who also runs a larger Jackery unit, is that the DC solar charge port is finicky and did not work with most third-party solar plugs, only Jackery's own cable.
