  1. High power capacity (290Wh) suitable for charging multiple devices​​.
  2. Portable and lightweight design with an easy-to-carry handle​​.
  3. Multiple charging options including solar, AC, and car outlet​.
  4. Built-in MPPT module increases solar charging efficiency by up to 23%​​.
  5. Pure sine wave AC outlet for stable power to sensitive electronics​​.
  6. Generally well-received with a high percentage of user recommendations​.


  1. Missing accessories like cables can impact initial usability​.
  2. Some users may require higher capacity for more demanding applications​​.
  3. Does not include a USB-C port, which is a limitation for charging modern devices directly without an adapter​​.


The Jackery Explorer 290 stands out as a commendable balance of portability, power output, and versatile charging options. Its 290Wh capacity strikes a fine line between bulk and utility, making it suitable for a wide range of outdoor and backup power needs without being overly cumbersome.

From an expert’s perspective, the integration of an MPPT charge controller is a significant advantage, optimizing solar charging efficiency which is crucial for off-grid and eco-friendly power solutions. The pure sine wave inverter is another technical merit, ensuring compatibility with sensitive electronics—a feature not always guaranteed in portable power stations.

However, the absence of a USB-C port and occasional accessory issues are oversights that slightly mar an otherwise impressive device. The USB-C port, in particular, reflects a missed opportunity to seamlessly support newer technology standards.

In sum, the Jackery Explorer 290 is a robust, user-friendly power station with room for minor improvements. Its practicality in real-world scenarios, coupled with high user satisfaction, positions it as a reliable companion for both adventurers and those seeking an emergency power backup.
