Key TakeawaysThis comparison breaks down the two products on capacity, AC output, charging speed, and portability.Differences in battery chemistry, expandability, port selection, and value help separate the better fit.Use-case analysis shows which option is stronger for home backup, camping, travel, or off-grid power.The final takeaway is less about one universal winner and more about which model fits the buyer’s priorities. The Bluetti EB150 and EcoFlow Delta 1300 share similar battery capacities, however, there are several differences that make these two unique from one another. Depending on what your power needs are, this article breaks down each model's specifications and features to help you decide on which one is best suited for you. The EcoFlow Delta 1300 is better than the Bluetti EB150 due to its powerful AC output and faster recharging times. Although the EB150 has a larger battery, lower cost, and higher battery cycle life, the Delta 1300 has nearly twice the AC output power of the EB150, at 1,800W (continuous). The Delta also has EcoFlow's X-Boost technology, which recharges the power station in less than two hours from its AC wall charger. This is nearly five times faster than the EB150's wall charging speed. Bluetti EB150 by Maxoak The Bluetti EB150 in its traditional blue and white color scheme. 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. Since this model came out, it has been surpassed by several Bluetti solar generators with more high-tech features. As a result, the EB150 was recently discontinued by Bluetti, but there are still units for sale on Amazon for a relatively low price of $799 on Amazon (affiliate link). The battery has a capacity of 1,500Wh and a load of 1,000W continuous (1,200W surge). Its 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 power 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 (45W max) 1 x Car port 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 1,000W at 110V Input There are two main ways to recharge the EB150: Connecting it to a wall socket Connecting it to solar panels You can also charge it via a car charger, but it takes longer to recharge than the other two methods. For someone who does not have solar panels, or when solar panels are not useful due to clouds or nighttime, plugging it into 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) into the battery input easily. Via solar panels, the battery can receive an open-circuit voltage from 16-60V at 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: 4x 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) 1x 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 use it as an input or output. 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. Car port which provides 12V/9A This port provides 12 volts DC and up to 9A, just as the port found in most cars. AC Outputs which can provide 1,000W 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 1,500Wh, the limit of watts that can be provided on one of these ports is 1,000W, 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. The Bluetti EB150's running times with various devices/appliances plugged in. By the way, devices that might not be able to be powered by the EB150 are: Microwaves (600-1,200W) Irons (800-2,000W) Hair dryers (800-1,800W) Space heaters (typically 1,500W+) These devices should be reviewed before you decide to use them with the EB150. You can find each of their wattage ratings by examining the physical product for their specifications. Extra Features Besides those specifications, the Bluetti EB150 has some extra features that come in handy: Maximum Power Point Tracking (MPPT) Pure sine-wave inverter Battery management system (BMS) *You can scroll towards the bottom of this post for definitions of the terms mentioned above. Included with the system This system comes with the following items: 1x Portable power station (EB150) 1x AC Wall Charger 1x PV Solar Charging Cable (DC7909 to MC4) 1x User Manual 1x Warranty Card (12 Months) 1x Certificate of Qualification Another model - EB240 The Bluetti EB240 is nearly identical to the EB150 except for its larger battery (2,400Wh). 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 1,500Wh, the EB240 has a capacity of 2,400Wh. 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 for regular or light use, the EB150 maintains as a great option. You can check out the EB240 on Amazon here for details (affiliate link). EcoFlow DELTA 1300 The EcoFlow Delta 1300 is the first power station in the Delta lineup. The Delta Mini, Delta Max, and Delta Pro are the other models from EcoFlow. On the other side of the ring, we have the Delta 1300 by 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 model has a price of $1,099, a battery capacity of 1,260Wh, and an AC output of 1,800W continuous (3,300W surge). 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: 6x AC Outputs which can provide 1,800W (3,300W surge) 1x Car port which provides 13.6V/8A (max) AC ON/OFF Switch On the front panel we find: A large LCD monitoring screen 2x USB-A outputs 2x USB-A Fast Charge outputs 2x USB-C outputs A DC ON/OFF Switch An ON/OFF Button On the side: 1x Car Charger / Solar Input with 10-65V/10A (max) 1x AC Input for 100-120V AC (50Hz/60Hz only) 1x Overload protection switch Input There are two ways to power this station: Connecting it to a wall socket The first way to charge the station is to plug it into a wall socket that 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. 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 into 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 The Delta 1300's output ports (on the front and back). Here will be listed the multiple outputs and their use: 2x 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) 2x 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 2x 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. 1x Car port 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. 6x AC Outputs which can provide 1,800W (3,300W 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 1,260Wh but it can provide 1,800W through these ports, with a peak wattage of 3,300W for starting large appliances. Extra Features Besides those specifications, the Delta 1300 has the same features: Maximum Power Point Tracking (MPPT) Pure sine-wave inverter Battery management system (BMS) Included with the system This system comes with the following items: 1x Portable power station (DELTA 1300) 1x AC Wall Charger (1.5m) 1x Car Charge Cable (1.5m) 1x PV Solar Charging Cable (XT60 to MC4) 1x User Guide 1x 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. Find more details on MPPT technology and its uses here Pure Sine Wave inverter 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 brain behind the battery. It manages a battery’s resources to prevent damage 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 which portable power station to buy. Similar: The Complete Solar Generator Guide Conclusion As can be seen, both of these portable power stations have similar characteristics, but they have some differences that might matter to your intended uses. As mentioned earlier, while the EB150 has a greater capacity than the Delta 1300, the Delta supports a greater load than the Bluetti model. 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.). The Delta 1300 has the better AC output and AC charging speed, but the EB150 costs about $300 less and its battery is rated for 2,000 cycles to 80% capacity (the Delta is rated for 500 cycles to 80%).
