The Evolution of EcoFlow

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.

The company boasts a proprietary battery management system as well as a new charging platform for AC current, both of which make the 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.

Pros of the EcoFlow Delta 1300

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 fully capable power system. 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).

Portability
At just over 30 lbs., the EcoFlow Delta 1300 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 1300

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 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 1300 Different - Key Takeaways & Comparison
Without a doubt, the 2 hour charge time of the Ecoflow Delta 1300 is the innovation that makes the generator standout amongst its competitors. However, when compared to the popular Yeti Goal Zero 1400, the Delta 1300 showcases quite a few improvements.

Side by Side Comparison: EcoFlow Delta 1300 vs. Yeti Goal Zero 1400

Charging TIme: Two Hours vs 25 Hours
Battery life cycle: 800 Charges vs 500 Charges
Shelf Life: 12 months vs. 3-5 months
Max Solar Input: 400 Watts vs 350 Watts
Output: 1800 W (Surge 3300W) vs 1500W (Surge 3000W)
Outlets: 6 AC, 6 USB vs 2 AC, 4 USB
Weight: 30 lbs vs 43 lbs
Price: $1,399 vs $1,899 

Conclusion - Is it Worth it?

Is the Ecoflow Delta 1300 solar generator worth it? Yes.

The value of the system at the retail price is hard to beat and the 2 hour AC charge time is truly revolutionary. The Delta 1300 comes with everything you need (besides solar panels), so it makes for the best possible plug-and-play option (no adapters necessary!). Feel free to check out the EcoFlow Delta user manual here as well.

The Ecoflow Delta 1300 is ideal for occasional use such as camping, tailgating, and festivals, and is also a perfect emergency back-up solution for homes, disaster situations and medical devices. Whereas we may not recommend the EcoFlow Delta as your daily life source of power, it is an incredible solar generator with great capabilities.
