If you are looking for an energy solution that allows you to keep your devices on no matter where you are, then it is very likely that you know about portable power stations, which offer multiple advantages over conventional alternatives such as gasoline generators, which are characterized by being excessively noisy, in addition to polluting and even being dangerous in uncontrolled environments.

Portable power stations not only stand out for offering quiet operation but also for allowing users to choose how they want to recharge the battery. Instead of relying solely on an outlet, you can take advantage of solar charging and thus save money in the long run. It is important to mention that the maximum power output offered by a portable power station will depend largely on the number of devices you will be able to connect.

One of the most recommended options by experts is the EF ECOFLOW Delta 2 solar generator, which includes a powerful portable power station and 2 solar panels, making it a perfect match for those who camp frequently or live in an area prone to blackouts (this increases significantly if you live in an area affected by hurricanes).

Now it’s time to get to know the main features of the EF ECOFLOW Delta 2

1800W output power

One of the most innovative features of this solar generator is that it includes a powerful portable power station, which offers a maximum power output of 1800W (peak of 2700W). The 1800W power output allows multiple devices to be connected at the same time without worry, which is often a problem in portable power stations with a maximum output of 1000W. Remember that to ensure the best performance, it is not recommended that the accumulation of connected devices exceed 1800W.

LiFePO4 Battery

The Delta 2 not only stands out for its powerful maximum output but also for incorporating a LiFePO4 rechargeable battery, which usually lasts more than 10 years or the equivalent of more than 3000 charge cycles. In addition, it has a high capacity of 1024Wh, allowing your devices or appliances to keep running for longer. On top of that, the LiFePO4 battery features super-fast charging technology, which means it’s possible to charge 80% in as little as 50 minutes (from an outlet).  EF ECOFLOW also allows you to expand the capacity up to a maximum of 3kWh if you decide to buy additional batteries (optional).

2 x 200W solar panels

The EF ECOFLOW Delta 2 solar generator includes everything you need to make the most of solar energy. 2 x 200W solar panels are included, which will allow you to charge the portable power station no matter where you are. These solar panels are significantly better than the competition, with a conversion efficiency of up to 23%, which will allow the portable power station to be charged in about 5.1 hours. Please note that solar panels are shipped separately due to logistical factors.

Now let’s compile the advantages and cons of the EF ECOFLOW Delta 2


  • High output power (1800W, 2700W peak).
  • Long-lasting LiFePO4 battery (+3000 cycles).
  • Expandable Battery
  • Fast charging (80% in 50 minutes).


  • Full solar charging time only under ideal conditions.
  • Higher initial cost compared to gasoline-powered generators.

In conclusion

The EF ECOFLOW Delta 2 is an efficient portable power station, offering 1800W of power (2700W at peaks) and a LiFePO4 battery that exceeds 3000 charge cycles. Equipped with solar panels for sustainable recharging, although its effectiveness is climate-dependent, this model stands out for its fast-charging capacity. Although its initial cost is high, its performance, portability, and charging capacity make it a solid choice for reliable power on the go.
