(Last Updated On: May 27, 2024)

The Bluetti AC240 Power Station is an impressive piece of equipment designed for serious power needs, whether for outdoor adventures or as a reliable backup during emergencies. With its heavy-duty construction, substantial power output, and water-resistant capabilities, the AC240 stands out as a versatile and dependable power station.

Design and Build Quality

The first thing you’ll notice about the Bluetti AC240 is its robust and hefty design. Weighing in at 72 lbs, this is not a lightweight device, but it’s built to last. The dimensions of 16.5 x 11.6 x 16.1 inches give it a solid presence, and it’s clear that portability here means moving it from one place to another, not necessarily carrying it around frequently.

One of the standout features of the AC240 is its IP65 water resistance rating. This means it can handle significant water splashes, making it suitable for use in less-than-ideal weather conditions. However, it’s important to remember that this rating does not protect against submersion, so dropping it into a pool or the ocean would still cause damage.

Power and Performance

At its core, the AC240 offers a 2400W max output, which can be boosted to 3600W using the powerlifting mode available through the Bluetti app. This makes it capable of powering a wide range of devices, from small electronics to more demanding appliances like heaters.

The battery capacity of 1536Wh is substantial, although not as large as some might expect given the unit’s size. However, this can be expanded significantly by connecting additional Bluetti B210 batteries, each providing an extra 2048Wh. This modularity is a big plus, allowing users to tailor their power setup to their specific needs.

Charging and Efficiency

The AC240 supports fast charging, with its AC charging cable capable of delivering up to 1800W in turbo mode. This means you can recharge the power station from 0% to 100% in about 1.5 hours, although the charging rate will slow down as it approaches full capacity. The device also features standard and silent charging modes for quieter operation, albeit at slower speeds.

Performance testing revealed that the AC240 has an 83% DC capacity efficiency and an 85% AC capacity efficiency, which is quite respectable. When combined with a B210 battery, the efficiency remains strong at 84%, showing that the power station maintains good performance even when scaled up.

Ports and Connectivity

The AC240 is equipped with a variety of ports to meet different power needs:

  • Two 100W Type-C power delivery ports
  • Two 18W Type-A ports
  • A 12V car socket (120W)
  • A 12V 30A outlet
  • NEMA TT-30 AC outlet for RV use
  • Standard AC outlets (2400W output, expandable to 3600W with powerlifting mode)

The user interface is straightforward and user-friendly, with a display that shows battery percentage, estimated runtime, and other vital information. The Bluetti app enhances this experience by providing remote control and monitoring capabilities, allowing you to adjust settings, check input and output wattages, and manage connected battery packs.

Practical Use and Testing

In practical use, the AC240 proved itself to be reliable and versatile. It performed well in various tests, including powering high-demand devices like heaters. In one test, it managed to run a 1500W heater continuously when paired with a B210 battery, demonstrating its capability to handle significant power loads.

The powerlifting mode, while useful, does have its limitations. It can increase the power output to 3600W, but this comes at the cost of optimal appliance performance, as the power station adjusts voltage and amperage to make it work. This mode is best used sparingly and with the understanding that it’s more of a workaround than a permanent solution.

Additional Features

The AC240 also functions as an uninterruptible power supply (UPS), with a switchover time of about 15 milliseconds. This ensures that connected devices remain powered during outages, which is crucial for sensitive electronics.

The build includes practical design elements such as handles for easier movement, though given the weight, you’ll want to lift with your legs. The power station also comes with various accessories, including an AC charging cable, RV power cable, MC4 to solar charging cable, and a grounding screw (which you’ll want to keep track of).

Final Thoughts

The Bluetti AC240 Power Station is a formidable power solution for those who need reliable, expandable, and versatile power. Its heavy-duty build, substantial power output, and water resistance make it suitable for a variety of scenarios, from outdoor activities to emergency preparedness.

While the weight and size may be a drawback for some, the performance and features it offers more than makeup for it. The ability to expand its capacity with additional batteries, combined with the fast charging capabilities and robust app support, make the AC240 a standout choice in the portable power market.

For those considering this power station, it’s a solid investment, especially if you anticipate needing substantial power in challenging conditions. The Bluetti AC240 combines rugged durability with advanced technology to provide a reliable power source wherever you need it.
