Bluetti vs Ecoflow

While many of the products we review here are readily available to purchase and operate without a license, we always recommend hiring a qualified electrician to install and demonstrate their use.

In some cases, improper use and installation may result in a breach of insurance. Even worse, you could be putting yourself or your family at risk as an incorrectly installed electrical device could start a fire. So, don’t risk it - seek the services of a fully licensed electrician instead.

Can’t Decide Between Bluetti and EcoFlow? No Problem!

If you’re on the hunt for a solar generator, you'll no doubt have come across companies Bluetti and EcoFlow, and frankly, it’s because they’re the best, which is why deciding between them can be quite tricky.

So, to help you figure out which brand is more suited to your green energy wants and needs, I’ve pitted two equivalent generators from each company against one another in the ultimate power supply showdown! 

Bluetti vs Ecoflow

The Contenders

Allow me to introduce our first contender, the Bluetti EB150, a small suitcase-style solar generator packing loads of lean, green power.

And our second contender is the EcoFlow Delta, a cooler-shaped solar generator with energy for days.


Pros

  • Excellent battery cycle life
  • Durable enclosure
  • Awesome built-in handle
  • User-friendly
  • LCD
  • More affordable
  • Large battery capacity

Cons

  • Underwhelming inverter surge wattage
  • So-so continuous wattage
  • Only 2 charging methods (both take quite a while)


Pros

  • Impressive surge wattage
  • Great continuous wattage
  • Durable design
  • Portable
  • 3 charging methods
  • UPS mode (sort of)
  • Superfast AC charging
  • Decent variety of outputs
  • LCD

Cons

  • Battery capacity is weak considering its overall power
  • Shorter battery cycle life

Bluetti vs Ecoflow Buying Guide

What Makes the Bluetti EB150 and EcoFlow Delta Suitable Contenders?

Where Can I Buy These Generators?

Portability

Cards on the table, both these generators are pretty heavy, but ergonomic handles take the sting out of lugging them around. The EB150 weighs 37.9 lbs and measures 14.6 x 6.5 x 14.4”, while the Delta weighs 30.9 lbs and measures 15.7 x 8.3 x 10.6”.

With cooler-style handles on each side, the Delta is designed more for sharing the load with someone else, so if you’re more of a solo wanderer, bear that in mind. I find the EB150, with its suitcase aesthetic and single handle, much easier to carry when I’m on my own, despite it weighing a fair bit more.

Verdict

I’m calling this round a draw, as they’re both highly portable devices in different ways.

Battery Power and Capacity

The EB150 tops out at 1000 watts, which is nothing to scoff out, but I found the 1200-watt surge capacity a little underwhelming. I mean, it can still power some seriously hefty electronics, but it falls short when it comes to some of the more demanding motor-driven appliances, such as large refrigerators.

EcoFlow’s Delta is a much more power-dense unit, boasting a max continuous load of 1800 watts and a peak rate of 3300 watts, which means, unlike the EB150, it can power demanding motor-driven electronics

Sounds like the Delta’s got this round wrapped up, right? But consider this: The EB150 has a 1500 Wh rating, while the Delta has a lackluster 1260 Wh rating. In other words, the Bluetti has a longer-lasting charge.

Verdict

The EB150 claws back a bit of dignity in terms of watt hours, but I can’t ignore the raw power of the Delta, so this round goes to EcoFlow

Battery Cycle Life

Battery cycle life refers to how many times a battery can be discharged and recharged before it kicks the bucket, so it’s an important spec to consider if you want to get your money’s worth out of a generator.

The Delta has a respectable service life of 800 cycles to 80%, but Bluetti’s battery tech just can’t be beat on this count. The EB150 is rated to last for an insane 2500 cycles to 80%.

Verdict

The EB150 dominates in terms of longevity.

As you can see, the Delta offers a little more in the way of charging methods, but that’s not all. It’s also - and I can’t stress this enough - insanely fast on the recharge — we’re talking 80% in about an hour using an AC outlet.

The EB150 falls well short in this round, as it can take up to 10 hours to draw a full charge from an AC outlet.

Verdict

The EcoFlow completely and utterly destroys the Bluetti EB150 in terms of both charging methods and speed.

Compatibility

Next, we’re taking a look at outputs, which are equally important as battery power and capacity, as they determine what kind of electronics a generator can power and how many it can power simultaneously.

The Final Verdict

EcoFlow and their amazing Delta power station have enjoyed the lion’s share of the wins in this head-to-head, so if your budget falls around the 1K mark, EcoFlow is undoubtedly the smarter choice.

Having said that, the Delta’s jaw-dropping power may be more than you need. If you’re only interested in keeping, say, your laptop, smartphone, and maybe a light or two juiced, then you can save yourself a few pennies and pick up the EB150 instead.

The good news is that no matter which generator you pick, you can rest assured that you’re getting an incredibly high-quality product that will last for years of adventures — woo!
