Methodology

How we compared these models

Comparison pages use the same scoring lens across price, runtime, charging, portability, and inverter capability so the verdict is consistent from page to page.

  • Specs are checked against the brand listing and our review notes whenever both units have been tested.
  • Capacity, output, charging speed, weight, and battery chemistry are compared side by side.
  • Category scores reflect typical buyer priorities, not just the highest headline wattage.
  • When a metric still depends on manufacturer data, we keep that limitation explicit in the write-up.

The EcoFlow River 3 and Jackery Explorer 300 are the two most popular ultra-portable power stations. At similar weights and prices, they target the same buyer. The key difference is battery chemistry: LFP versus NMC.

The Battery Chemistry Gap

This is the biggest differentiator. The River 3's LFP battery lasts 3,000+ cycles to 80%. The Explorer 300's NMC battery lasts about 500 cycles. If you use either station once a week, the River 3 lasts 57 years (functionally: forever). The Explorer 300 lasts about 10 years. If you use them daily, the River 3 lasts 8+ years. The Explorer 300 lasts about 1.5 years.

For occasional users, the gap is academic. For daily users, it is decisive.

Charging Speed

The River 3 charges from empty to full in about 48 minutes. The Explorer 300 takes about 2 hours. That is a 2.5x speed difference. If you need to top off before heading out, the River 3 is ready in under an hour.

Capacity vs Features

The Explorer 300 has 48Wh more capacity (293Wh vs 245Wh), which translates to about 2 extra smartphone charges. The River 3 counters with a 100W USB-C PD port that fast-charges modern laptops and phones, while the Explorer 300 has only a basic USB-C port.

Portability

Both weigh under 8 lbs and fit in a daypack. The Explorer 300 is 0.3 lbs lighter. In practice, you will not notice the difference.

Which Should You Buy?

Choose the River 3 if:

  • You plan to use the station frequently (weekly or more)
  • Fast charging matters to your schedule
  • You want USB-C PD for modern device charging
  • You prefer a lower purchase price ($199 vs $249)

Choose the Explorer 300 if:

  • You need the extra 48Wh of capacity
  • You prefer Jackery's brand and simplicity
  • Usage is occasional (a few times per month)
  • You already own Jackery solar panels

For most buyers, the River 3 is the smarter pick. The LFP battery and faster charging outweigh the Explorer 300's small capacity advantage.
