The EcoFlow Delta 1300 solar generator is one of the greatest improvements in compact solar technology. This singular invention caused quite an uproar when it was invented in 2019. It was sponsored by Kickstarter who contributed about 2.8 million to the project.

This solar power station is the newest invention of EcoFlow Company. Established in 2017, EcoFlow deals with the production of powerful, handy batteries as well as other power tools

Today, the EcoFlow Delta solar generator is one of the best solar power stations found on the market. Their efficiency can be attributed to the fact that they use a modern charging platform for Alternate Current.

Why We Love The EcoFlow Delta Solar Generator

Quick Charging 

The EcoFlow’s ability to charge very fast is one of the attributes that gained it an enviable spot on the market. With an AC outlet, battery power increases by 80 percent in just one hour. It gets fully charged in less than two hours.

This product is ten times faster and stronger than other similar products such as the Suaoki Portable Solar generator. When the battery is totally used up, it requires just two hours of charging to get it back up and ready.

High Output 

In addition to having an amazing input capability, its electric output is also found to be impressive. This AC output is electrified by a 1800W inverter to provide a totally capable power system. With this setup, you can plug anything into a classic AC outlet with a rating of 110V. Such things as your TV, your laptop, or your lights can be kept running for a very long time.


This compact product is small enough to be carried to wherever it is needed. It weighs just a little over 30 Ibs and can easily fit into a backpack. Just like every other solar power generator, such as the Peppermint Energy Forty, it is eco-friendly and dispenses no harmful emissions into the environment. 

You can freely use it anywhere at any time, both outdoors, indoors, inside a tent, or even inside a van. This device is made from high-quality materials and is free from possible damage, especially during transportation.

Low cost

Looking at the real value you’ll get from using this powerful tool, the EcoFlow Delta generator price is considered to be affordable by many of the recent buyers. Besides being an alternative power source, this generator can help you save some money on your energy bills. The other product that comes close in terms of affordability is the EcoFlow River 370 which is significantly cheaper. 

Looking at the best solar generator comparison, the EcoFlow Delta 1300 has the capacity for 400W solar input while the River 370 model comes with 120W. Among other things, these solar power generators can be used as a home backup and for professional purposes like woodworking. 

Some Possible Downsides

Degradation of Battery

The Delta 1300’s battery is designed to sustain a 70% capacity after 800 charges. If this solar generator is your daily source of power, expect the 800 charges sooner than later. 

After the first 800 charges, of course, the device might still be functional but it will run at a less efficient pace. It will need to be charged more often causing the battery to degrade at a quicker rate.

That is why we advise that you use solar generators as a backup plan and not a regular source of power.

Low Round Trip Efficiency 

Round Trip Efficiency is the measure of electrical power gotten out of a battery vs that which was supplied into it. 

In an efficient system, the measure of this value should be around 70% but the EcoFlow Delta 1300 records only 58% RTE. Low Round Trip Efficiency causes no serious damage if the device is only used as a backup plan.
