EcoFlow Delta Vs. Goal Zero Yeti 1400 Lithium

Goal Zero is absolutely a trendsetter in the portable power market. For over a decade, it has been featuring an award-winning line-up of Yeti power stations. Of which, Yeti 1400 Lithium looks to be the most suitable model that visibly shares the specs and price attributes with the EcoFlow Delta power station.

So, it will be helpful for a buyer to get through a comparison of the devices before venturing to pick one. What I feel at a glance is that EcoFlow Delta downright outdoes Yeti 1400 with its lightweight profile and multiple charging points. But only a complete go-through will give us a clear picture, though, stay tuned.

EcoFlow Delta Vs. Goal Zero Yeti 1400 – Specs and Features

When it comes to specs, we would like to begin with the storage capacity. As you see, EcoFlow Delta falls short to Yeti 1400 in this case. As its title suggests, Delta features only 1260Wh capacity with a 350Ah @ 3.7V battery. Its Yeti rival just outplays it with a 1425Wh size and a 396Ah @3.6V battery.

However, Delta renders a high output. With its 1800W pure sine wave inverter that has a surge of 3300W, it wins over Yeti 1400. Meanwhile, Goal Zero integrates its famous 1500W pure sine wave inverter that can surge up to only 1500W. That said, the former is ideal for supporting more high-surge appliances.

Goal Zero Yeti 1400 Lithium

Moreover, there is something exceptional with Delta when it comes to AC outlets. As you know, it equips six AC sockets, including three full-size units as per the American standards. In short, you get a chance to run more powerful appliances on the power station. Of course, it supports more devices at the same time.

Besides, EcoFlow has its Delta with four USB-A ports and two USB-C ports apart from a 12V carport. Of the four USB-A outlets, two are Quick Charging ones as well. In total, you get six USB outlets in place of Yeti’s four ports, which also include two USB-Cs, however. Yeti also has a carport.

When it comes to the form, Yeti 1400 is just a boxy one. It has got two solid handles at both ends for easy moving. Meanwhile, the Delta power station is a squarish one with dual handles like Yeti. Regarding the weight, Delta is pretty light with just 30.9lbs, while Yeti is hefty at 43.7 lbs, thanks to its big battery.

EcoFlow Delta Vs. Goal Zero Yeti 1400 – Customer Reviews

Though EcoFlow claims its product is very silent, it doesn’t turn out so as per customer reviews. The dual cooling fans of the device make much noise both when you charge it from an AC plug and draw the power from it. Indeed, many reviewers have pointed out it as a flaw of the much-hyped EcoFlow Delta.

Compared to Yeti 1400, it is a significant shortfall. Yeti is very silent. Delta, in the meantime, is noisy even when the battery is full. The fans run very loud, perhaps to cool down the unit. But noise is tough to experience for a user, who may have gone for it only because of its noise-free operation.

Meanwhile, Delta charges quite quickly. As per its maker’s claim, it does charge entirely in just two hours on a wall socket. Several reviewers have tested it out and proven. Solar charging is also reportedly slightly faster. It is when Yeti 1400 takes several hours for a full charge on a wall socket as well as a solar charger.

EcoFlow River 370 Portable Power Station

By the way, let us have a sneak peek at a low variant of EcoFlow solar power stations. Inevitably, the brand has been selling this product for a while. It is a 370Wh power station with an output of 500 watts. That is, you can comfortably run your gears under 500 watts using it.

The EcoFlow Delta solar generator is undoubtedly the big brother of this model. But this one is for small-scale users. So far, it has been one of the top-seller portable solar power generators on the market with a lot of takers. Check out the link below to see its latest price and buy a unit if you love it.

Moreover, the machine has got as many as nine charging output ports. They include two AC sockets that can output 300 watts and 600 watts surge. Furthermore, it sports two Power Delivery USB-C ports, as many USB Quick Charge ports and regular USB ports, and more.

When it comes to a suitable solar charger, EcoFlow offers an excellent 85W folding solar charger. That is made of highly-efficient mono solar cells. The charger is also ideal for the brand’s other popular power station, called the EcoFlow 412Wh power station. Maybe, it will be working with the new EcoFlow Delta as well. Check out its latest price on the link above.

EcoFlow River 600 Portable Power Station

It is simply yet another lite variant of EcoFlow River power stations. It is originally a 288Wh machine, but you can take its storage capacity to 576Wh with a River 600 Extra Battery pack (paid link).

That is indeed the most attractive thing with River 600, which makes it a super cool modular power station. EcoFlow unveiled it on Kickaster with a battery module and a 1152Wh pro variant, as well.

River 600 features ten charging outlets to let you power up as many devices simultaneously. The charging options include three pure sine wave AC sockets with a normal output of 600 watts and a surge of 1200 watts. But thanks to the included X-Boost mode, it can power up even a 1800W appliance.

Interestingly, X-Boost has got an advanced algorithm to enable it to power up most large home appliances. The included EcoFlow app makes you monitor the X-Boost mode.
