Introduction

Bluetti and EcoFlow have made waves in the world of portable generators ever since their first power stations hit the market.

It’s not hard to see why. Increasing concerns over the environmental impact of how we produce our electricity have driven demand for access to clean, renewable energy.

In this article, we’ll take two of the most popular solar generators from these companies, the eb150 and the Delta 1300 to see how they compare.

If you’re still unsure about which power station works best for you, check out the FAQ section at the end where we answer some important questions.

EcoFlow Delta versus Bluetti eb150

Technical Spec

Charging

A prolonged charge time is every generator operator’s worst nightmare. Both the Bluetti eb150 and the EcoFlow Delta 1300 are marketed as portable power stations for people on the go. So it’s important that the batteries charge quickly.

Both the Delta and the eb150 can be charged with solar panels, which we’ll cover later in the article. For now, we’ll look at how these generators compare when charging directly from an AC wall outlet.

The Bluetti eb150 has a relatively small inverter, rated at 1,000W. This significantly limits how quickly the device can be charged. 

From 0%, the battery will take over 9 hours to recharge fully. This can be problematic if you’re looking for a power station that’s ready to go at a moment’s notice.

On the other end of the spectrum, the Delta has astonishingly fast charge times. 

EcoFlow uses patented X-STREAM technology that manages the power draw and output of each of the 100 Lithium-ion cells individually. This is what allows the generator to charge so quickly.

The Delta can be charged from 0% to 80% in an hour. This makes it the clear winner in terms of charge time and ease of use.

Power Outlets

The number of power outlets a generator has can greatly increase its versatility in your home. A battery with a large capacity is good, but it doesn’t do much if you can only power one device at a time.

The Delta has an impressive number of outlet options for you to choose from. In addition to the 6 110V AC power outlets, there are 4 USB sockets, two of which are fast-charging.

There are another 2 USB-C outlets for newer devices and a 12V DC car outlet. 

Not only do each of these outlets give you more space to power appliances, but they’re also capable of charging your battery. This means you can top up your power station from your car while you drive.

In this area, the eb150 is severely lacking. There are only 2 AC ports which means you have to use a multiplug if you want to power more devices. This is bad for your battery’s lifespan and makes a power surge more likely.

The eb150 has 4 standard USB ports, but no USB-C. It also lacks any 12V car outlets.

The number of AC power outlets alone would put the EcoFlow Delta ahead of its competitor. However, all the extra ports make it an even more convincing winner.

Capacity

The capacity of a portable generator is perhaps its most important feature. The amount of energy a battery bank can store will determine which kinds of appliances you can run and for how long.

The 1,500Wh capacity of the eb150 is a tough number to beat. This gives the generator the ability to power small electronic devices, such as cellphones and laptops, hundreds of times before being depleted.

The high capacity also makes it a viable option to power bigger appliances. A standard 800W microwave could be powered for nearly two hours continuously before draining the battery.

The Delta has a similar capacity, but it falls just shy of the eb150’s storage. The Delta is rated at 1,260Wh. This is more than enough to keep small electronics going for a long weekend camping trip.

The 240Wh difference in capacity between the two generators will only make itself felt once you have to run big appliances for a long time. Where the eb150 could power a mini-fridge for 25 hours, the Delta would only manage 21 hours.

This may not seem like much, but it could mean the difference between fresh, crisp veggies and soft, inedible ones. For this reason, the eb150 gets the edge over the Delta.

Bluetti EB150 or EcoFlow Delta

The EcoFlow Delta and Bluetti eb150 were both designed to give people access to clean, renewable energy at a reasonable price. But, while they both have the same aims, they perform quite differently.

In this section, we’ll give a short review of the eb150 and EcoFlow Delta to find out which generator is king.

Bluetti EB150

The Bluetti eb150 was released along with the eb240 in 2019. They are manufactured by MaxOak, who released their product after a successful round of crowdfunding.

The generator has an appealing design finished with high-quality plastic and brushed steel. Despite this, the generator itself is sturdy and durable, making it a great choice for bringing electricity to the great outdoors.

A key feature that adds to its durability is its impressive heat tolerance. The battery cells are kept in a highly insulated body, which greatly increases the longevity of the generator.

This clever design, along with other smart manufacturing steps, is what gives the eb150 an impressive 2,500 full charge cycles. The Bluetti eb150 charge cycles mean the battery will last for nearly 10 years, even with heavy usage.

One area where the eb150 truly excels is its solar charging. The advanced MPPT charge controller increases the output of photovoltaic cells. This brings the charge time down from 10 hours to 3 in ideal weather conditions.

So if you’re going to commit to an eb150, make sure to invest in solar panels to get the most out of it.

Pros

• Lightweight and portable.
• Modern design underlies a sturdy interior.
• Excellent solar charging.

Cons

• Very limited power outlets.
• Prolonged AC outlet charge time.

EcoFlow Delta

EcoFlow rocketed into solar generator enthusiast’s spotlight in 2017 when they released the River. In 2020, the company launched the EcoFlow Delta 1300 and it’s been getting rave reviews and racking up industry accolades ever since.

Like the eb150, the Delta comes with an MPPT charge controller that increases the efficiency of solar charging. Although it’s not as sophisticated as Bluetti’s, the EcoFlow can fully charge in around 4 hours in good weather.

However, it’s not all positive. The Delta has a poor charge efficiency rating at just 58%. This means that 42% of the power that goes into charging the device is lost to heat and resistance.

The Delta also has a surprisingly large power inverter, rated at 1,800W. This allows you to power appliances that draw up to 1,800W of power. This is 800W more than the inverter on the eb150.

To illustrate this difference, the Delta could power a 1,500W air fryer for just over 50 minutes. However, despite the eb150’s bigger capacity, the smaller inverted means that the generator would trip. This makes the Delta a more versatile option for most users.

Pros

• Superfast charge times.
• High power output.
• Plenty of power outlets.

Cons

• Noisy running.
• Low charge efficiency.

EcoFlow Delta and Bluetti EB150 FAQs

Is the Bluetti eb150 better than the EcoFlow Delta

For our money’s worth, no.

There are some great features on the Bluetti that make it a great purchase. It’s $100 cheaper and has more capacity.

However, the Delta has more features that make it a good purchase no matter your needs.

Is eb150 the biggest Bluetti generator?

No.

MaxOak also sells the Bluetti eb240. These two power stations are quite similar. They have the same number of power outlets, the same peak power output, and the same level of surge protection.

However, the eb240 vs the eb150 has nearly double the capacity. The generator has a whopping 2,400Wh capacity, which can power a mini-fridge for over 40 hours in comparison to the eb150’s 21.

What other options are there?

Another massively popular portable power station is the Jackery 1000. 

The Jackery was made with durability and transportability in mind. The eb150 vs the Jackery 1000 has a similar number of power outlets and they have the same 1,000W peak power output.
