REVIEW: EcoFlow Delta 1300/1800 Solar Generator Pros, Cons & Complete Review

EcoFlow Delta 13001800 Solar Generator

Short on Time? Here’s The Article Summary

The EcoFlow Delta 1300 is a portable solar generator that gained significant attention after raising over $2.8 million in a Kickstarter campaign. It features a 1300Wh capacity, 1800W inverter, and a variety of outlets for different devices. The generator can be charged via solar panels (up to 400W), AC outlet, or a vehicle's carport, with a full charge achieved in about 4 hours with solar panels.

Pros include its fast charging, high output, portability, and affordability, retailing around $1,400. However, it has cons such as potential battery degradation after 800 charges and a low round trip efficiency of around 58%. Compared to the Yeti Goal Zero 1400, the Delta 1300 offers faster charging, longer battery life cycle, and more outlets. Overall, the EcoFlow Delta 1300 is recommended for occasional use like camping or as an emergency backup, but not for daily, long-term power needs due to potential battery degradation.


The Evolution of EcoFlow Delta

The EcoFlow Delta 1300 solar generator is one of the most exciting advances in portable solar technology, and created an enormous amount of buzz in late 2019.  Funded by a Kickstarter that raised over 2.8 million, the Delta is the latest product from the portable power company EcoFlow, which began producing powerful, portable batteries in 2017.   

EcoFlow boasts a proprietary battery management system as well as a new charging platform for AC current, both of which make the EcoFlow Delta 1300 one of the most efficient solar generators on the market today.  In this article, we will outline the pros, cons, and capabilities of the EcoFlow Delta 1300 solar powered generator

Pros of the EcoFlow Delta 1800 Solar Generator

Seriously Fast Charging

The popularity of the EcoFlow Delta 1300 can largely be attributed to its super fast charging.  When plugged into a standard AC outlet, the Delta’s battery bank will go from zero to 80% charged in only one hour.

The battery will reach a full charge in as little as two hours. This rapid charging rate is an astounding 10 times faster than most other solar generators available today.  This means that if you end up using all the battery, it will only take you 2 hours to charge it back up and you’ll be ready to go again. 

High Output 

Not only is the input capability of the Delta 1300 impressive, but the electric (AC) output powered by the 1800W Inverter rated at 3,300W for surge protection creates a super powerful solar generator (one of the most powerful). 

This means that anything that can be plugged into a traditional AC outlet (rated at 110V) like your laptop, TV or lights, can be easily powered by the Delta 1300 for a long time. The Delta 1300’s 13.6V DC output also provides more than enough power to continuously run a DC powered fridge in a van or an RV for 8-10 hours (all night long if need be).


At just over 30 lbs., the EcoFlow Delta 1300 solar generator is light enough to bring wherever power is needed.  Like all solar power generators operating with no harmful emissions, the Delta 1300 can be used indoors, outdoors, or inside a tent, RV, or van.  The high quality of the product’s hard nylon shell also keeps the system free from potential damage.  

Low Price

Retailing at roughly $1,400, the EcoFlow Delta 1300 is an extremely affordable option for the high quality components and overall convenience of the portable solar generator. Not only does the Delta 1300 come with a large, high quality inverter, charge controller and battery, but all of the charging cables are included when the product is purchased.  Factor this in with a 2 year manufacturer's warranty, and the Delta 1300 is a great option for a low price. 

Cons of the EcoFlow Delta 1800 Solar Generator

Battery Degradation

The battery included in the Delta 1300 is rated to hold a 60% capacity after 800 charges.  If you are planning to use this solar generator for a standalone, daily source of power, 800 charges will approach quickly in under three years time. 

Although it is true the system will still be able to be used after its initial 800 charges, running at a 60% battery capacity will lead to an increased amount of charges needed and therefore even quicker battery degradation.

Low Round Trip Efficiency

Initial product tests of the EcoFlow Delta 1300 solar generator have found that the system only has an approximately 58% round trip efficiency.  Round trip efficiency is simply the amount of power that can be drawn out of the battery when compared to the amount of power that was put into the battery. 

In most efficient systems, this should be around 70%. This factor is not critical if the generator is used sparingly or as a back-up, but the low round-trip efficiency implies that more power is needed to fill the battery than traditional solar power systems.

What Makes the Ecoflow Delta 1800 Different - Key Takeaways & Comparison

Without a doubt, the 2 hour charge time of the Ecoflow Delta 1300 solar generator is the innovation that makes the generator standout amongst its competitors (Consider checking our next blog EcoFlow Delta 1300 vs Jackery 1000 or learn more about EcoFlow Delta 1300 Alternatives).  However, when compared to the popular Yeti Goal Zero 1400, the Delta 1300 showcases quite a few improvements.
