Bluetti EB150 vs EcoFlow Delta 1300 – Which Solar Generator is Best?

In this modern world, everything runs on electricity. We live among electronic devices, from our phones to our refrigerator; from our computer to the electric heater we use to keep warm during winter.

We rely on these devices because they have made our life easier, but electricity has to be brought from somewhere. We take for granted the enormous power stations that generate our electricity, the power lines that transport it, and the infrastructure that distributes it through our houses, buildings, and offices.

That is why, when we go somewhere where electricity is not available, or when there is a power shortage, we stand puzzled with our chargers in our hands wondering where are we supposed to get electricity from. That is where solar-powered generators come in handy.

Huge generators that work on diesel or natural gas, such as the ones used for backup in hospitals and prisons, are essential in situations where great wattage is required over long periods of time. But for personal use, or on light usage on a household, a portable power station can be a lifesaver. This is because it has the power you need without the fumes and pollution from a gas generator.

In this article we will compare two different portable power stations:

  • Bluetti EB150
  • EcoFlow Delta 1300

The Bluetti EB150 vs EcoFlow Delta 1300 – Which solar generator is better?

While the Bluetti EB150 has a greater capacity than the Delta 1300 (1500Wh over 1260Wh), the Delta 1300 supports a greater load than the Bluetti EB150 (1800W over 1000W). This can make a difference over someone that is looking for light usage over a long time (e.g. camping, watching tv, etc.) over someone that might want great power over a limited time. (e.g. a party, an event, etc.).

These two power stations can satisfy similar consumers’ needs and, to the inexperienced eye, they might seem to be the same thing. But in this article, we will analyze their similarities and their differences, not to select a winner, but to decide which one is better for different situations.

Bluetti EB150 by Maxoak

MAXOAK Portable Power Station BLUETTI EB150 1500Wh AC110V/1000W Camping Solar Generator Lithium Emergency Battery Backup with 2 AC outlet Pure Sinewave,DC12V,USB-C for Outdoor Road Trip Travel Fishing

The first generator we’ll be discussing is the Bluetti EB150. This portable power station was designed and created in Shenzhen, or as some people call it: China’s Silicon Valley. 

This has a price of $1099 via shopsolarkits.com.

The battery has a capacity of 1500Wh and a load of 1000W (Max). It also has an overload capacity of 1000W ≤load<1200W @2Min; 1200W≤load @1s. It is charged via solar panels and/or an AC outlet and it outputs both DC and AC (Alternating Current).

The first thing we notice is its shape that resembles kind of a futuristic suitcase with a handle on the top made for carrying it. The blue color on its sides contrasts with the white on the front, the back, and the handle. You can also get the unit in black instead of the blue sides.

The station has the size of about a computer CPU, measuring 14.6” x 14.4” x 6.5” and with a weight of 38 lbs. It is, naturally, a heavy machine, but not so much considering its capabilities.

On the back panel we find the following:

  • The input connector which accepts 16-60V DC
  • 1 x PC Type-C connector for USB-C devices. (Max 45W)
  • 1 x Carport which provides 12V/9A
  • 4 x USB-A ports which provide 5V/3A (Max)
  • ON/OFF, AC, and DC buttons
  • A monitoring screen

On the front panel we find:

  • 2 x AC Outputs which can provide 1000W at 110V

Input

There are two ways to power this station:

  1. Connecting it to a wall socket
  2. Connecting it to solar panels

For someone who does not have solar panels, or when solar panels are not useful due to clouds or nighttime, plugging it to a wall socket is an easy solution, just as you would charge any electronic device. (AC wall charger included)

The battery takes from the wall socket 42V/160W and it can be completely charged in 10 hours.

One of the greatest benefits of this battery is the ability to charge it with solar energy. This product includes a DC7909 to MC4 cable* so you can plug a solar panel or a solar panel array (a set of solar panels) to the battery easily.

The battery can receive from the solar panels open-circuit voltage from 16-60V (Max) and 500W max.

*The DC7909 connector is the one that is connected to the battery. The MCA4 connector is a standard used to connect to a solar panel.

Output

Here will be listed the multiple outputs and their uses:

1. 4 x USB-A ports which provide 5V/3A (Max)

These are the traditional USB ports for charging small electronic devices such as cellphones, small speakers, etc.

It provides 5V, which is the standard on USB, and also up to 3A of current. Not many USB devices go up to 3A, but it is good to have that option.

(Example: An Apple 5W USB power adapter used for charging an iPhone provides 1A of current)

2. PC Type-C connector for USB-C devices. (Max 45W)

The USB-C is a newer connector, soon to replace the USB-A, so it is logical that this system has one. It has many advantages over its predecessor:

  • It has no orientation, so you can connect it either side.
  • It will be universally used. Almost all new devices come with a USB-C port.
  • Supports data transfer of up to 10 Gbps.
  • Supports USB PD, so it can deliver power.
  • Faster charging than USB-A.

3. Carport which provides 12V/9A

This port provides 12 volts DC and up to 9A, just as the port found in most cars.

4. AC Outputs which can provide 1000W at 110V

These might be the most important ports on the device. An inverter is used to turn the DC on the battery into AC, which is the type of current that comes out of the wall sockets on a house and generates the 110V provided, which is the standard for many countries, including the ones in North America.

Even when the battery has a capacity of 1500Wh, the limit of watts that can be provided on one of these ports is 1000W, but few common devices take more than that wattage, so you can connect and charge most of your devices. Below is a picture with examples of how much time you can charge certain devices:

By the way, devices that might not be able to be powered by the EB150 are:

  • Microwaves (600-1200W)
  • Irons (800-2000W)
  • Hair dryers (800-1800W)
  • And other high-power devices.

Extra Features

Besides those specifications, the Bluetti EB150 has some extra features that come in handy:

  • Maximum Power Point Tracking (MPPT) (Explained below)
  • Pure sine-wave inverter (Explained below)
  • Battery management system (BMS) (Explained below)

Included with the system

This system comes with the following items:

  • 1 x Portable power station (EB150)
  • 1 x AC Wall Charger
  • 1 x PV Solar Charging Cable (DC7909 to MC4)
  • 1 x User Manual
  • 1 x Warranty Card (12 Months)
  • 1 x Certificate of Qualification 

Another model

Another model of the same manufacturer that is similar is the Bluetti EB240. There are not many differences between them but, as the name might show, while the EB150 has a capacity of 1500Wh, the EB240 has a capacity of 2400Wh. This means that fully charged and operating under the same demands and the same conditions, the EB240 should last 60% longer. Also, since the battery has a greater capability, it has a larger size of 19.4” x 14.4” x 6.5”.

This EB240 model is a good alternative if the user is expecting to use the battery for longer periods, but as for regular or light use, the EB150 maintains as a great option.

EcoFlow DELTA 1300

EF ECOFLOW Portable Power Station DELTA, UPS Power Supply 1260Wh Battery Pack with 6 1800W (3300W Surge) AC Outlets, Solar Battery Generator for Outdoor Camping RV

On the other side of the ring, we have the Delta 1300 by the company Ecoflow, a company founded by a team of entrepreneurs who used to work on developing the perfect drone battery. Now they use their experience for creating lightweight, long-lasting, and powerful power stations. 

This has a price of $1199 through shopsolarkits.com.

This battery has a capacity of 1260Wh and a load of 1800W (Surge 3300W). It outputs both DC and AC (Alternating Current).

This portable power station has a more industrial look, with different tones of gray it gives a more modest impression. It has a handle both in the front and in the back so you can grab it easily.

The station is smaller than the EB150, measuring 15.7” x 10.6” x 8.3” and a weight of 31 lbs.

On the back panel we find the following:

  • 6 x AC Outputs which can provide 1800W (3300W Surge)
  • 1 x Carport which provides 13.6V/8A (Max)
  • AC ON/OFF Switch

On the front panel we find:

  • 1 x AC Input for 100-120V AC (50Hz/60Hz only)
  • 1 x Overload protection switch

Input

There are two ways to power this station:

1. Connecting it to a wall socket

The first way to charge the station is to plug it to a wall socket which provides 100-120V AC, just as you would charge any electronic device. (AC wall charger included)

The battery can be 80% charged in one hour, and 100% charged in 1.6 hours.

2. Connecting it to solar panels

This battery can also be charged with solar energy. This product includes an XT60 to MC4 cable* so you can plug a solar panel or a solar panel array to the battery easily.

The battery can receive from the solar panels 10-65V (Max), at a max wattage of 400W.

*The XT60 connector is the one that is connected to the battery. The MCA4 connector is a standard used to connect to a solar panel.

Output

Here will be listed the multiple outputs and their use:

1. 2 x USB-A traditional outputs

Traditional USB ports for charging small electronic devices. It provides 5V, which is the standard on USB, and up to 2.4A of current. 

(Example: An Apple 5W USB power adapter used for charging an iPhone allows 1A of current)

2. 2 x PC USB-A Fast Charge outputs 

These are just like the traditional USB ports, except that these provide different voltages (5V, 9V, and 12V) with 2.4A

3. 2 x USB-C outputs

As explained earlier, the USB-C will be the norm in the future, it has been slowly replacing the traditional USB-A, providing faster charging and can provide different voltages. (5V, 9V, 12V, 15V, 20V) with 3A.

4. 1 x Carport which provides 13.6V/8A (Max)

This port provides about 12 volts (13.6V max) DC and up to 8A, just like the port found in most cars.

5. 6 x AC Outputs which can provide 1800W/3300W Peak

These are the main outputs on the device. As it happens on the previous battery, an inverter is used to turn the DC on the battery into AC, which is the type of current that comes out of the wall sockets on a house and generates the 110V provided, as is the standard for many countries, including the ones in North America.

The battery has a capacity of 1260Wh but it can provide 1800W through these ports, with a peak wattage of 3300W for extreme conditions.

Extra Features

Besides those specifications, the EcoFlow Delta 1300 has the same features:

  • Maximum Power Point Tracking (MPPT) (Explained below)
  • Pure sine-wave inverter (Explained below)
  • Battery management system (BMS) (Explained below)

Included with the system

This system comes with the following items:

  • 1 x Portable power station (DELTA 1300)
  • 1 x AC Wall Charger (1.5m)
  • 1 x Car Charge Cable (1.5m)
  • 1 x PV Solar Charging Cable (XT60 to MC4)
  • 1 x User Guide
  • 1 x EFDELTA Bag

Another Model

Another model of the same manufacturer that is similar is the EcoFlow River 370. This model is rated at about 1000 Watt-hours less than the DELTA 1300. It is a good alternative for shorter usage and lower requirements.

Read my full review of the River 370 here for more features: EcoFlow River 370 Review (Internal Tech, Features, and More).

Maximum Power Point Tracking

Both systems have a Maximum Power Point Tracking (MPPT) charge controller built-in.

This MPPT is a DC to DC converter that uses high frequency to optimize the match between the solar panel, or the solar array used, and the battery.

Basically, it converts a high DC voltage from the solar panels to a lower voltage that fits the battery.

Solar panels work better in cooler temperatures, but if no MPPT is applied, most of the benefits of the cold are lost.

Also, the MPPT decides to put more current into the battery when the charge is low, and vice versa.

Another benefit is that if the solar panels are far from the device, they can be wired in series to obtain a higher voltage, then transmit that high voltage over long wires to arrive at the device in where the MPPT will reduce the voltage to fit the battery, and this would be a way to lose the least possible energy in the process.

This last benefit is a minimalistic and similar approach to how voltage is increased to reduce energy wasted when transporting electricity over power lines across the country.

Pure Sine Wave inverter

Pure Sine Wave animation

Pure Sine Wave inverters produce clean and reliable power, like the one that is usually received from the utility company. Many devices and appliances run much more efficiently with a pure sine wave inverter, such as refrigerators, compressors, microwave ovens, and many electronics.

Battery Management System

The Battery Management System (BMS) is basically the brains behind the battery. It manages a battery’s resources to prevent damages to the unit and reports the status of crucial information. 

One BMS function is overvoltage protection when a battery is overcharged. It also makes sure that the battery does not discharge below a certain threshold (typically about 5% of total capacity) because it could cause long-term problems.

Another function of the BMS is energy management, which helps us monitor the charge left in the battery and the time left before the battery runs out given actual usage.

Most batteries inside electronics possess these or some of these features, but it is a good thing to keep in mind when deciding over which portable power station to buy.

Conclusion

As can be seen, both of these portable power stations have similar characteristics at the same price, but they have some differences that might matter to a potential consumer. 

As mentioned earlier, while the Bluetti EB150 has a greater capacity than the Delta 1300, the Delta 1300 supports a greater load than the Bluetti EB150.

This can make a difference over someone that is looking for light usage over a long time (e.g. camping, watching tv, etc.) over someone that might want great power over a limited time. (e.g. a party, an event, etc.).

Besides that, both of them achieve their purpose with a cool design and a lightweight body.

It might depend on the type of buyer for which of these generators to choose from, but this information might help potential users decide which one to get and what to expect from them.
