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.
Specs at a Glance
| Spec | River 3 | Explorer 300 | |------|---------|--------------| | Capacity | 245Wh | 293Wh | | Output | 300W (600W surge) | 300W (peak) | | Weight | 7.8 lbs | 7.5 lbs | | AC Charge | ~48 minutes | ~2 hours | | Battery | LFP, 3,000+ cycles | NMC, 500 cycles | | USB-C | 100W PD | Basic USB-C | | Price | $199 | $249 |
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.
