Overview
Bluetti is expanding its lineup of portable power solutions with the AC240, a unit that appears squarely aimed at users who require both significant power and resilience against the elements. With a substantial base capacity and high output, the AC240 distinguishes itself in a crowded market with its IP65 water and dust-resistance rating, a feature not commonly found in power stations of this size. It's positioned as a durable power source for RV and boat owners, off-grid enthusiasts, and professionals on rugged job sites.
Beyond its tough exterior, the AC240 offers a highly modular and expandable ecosystem. While its starting capacity is 1,536Wh, it can be expanded more than six-fold, and its output can be doubled by pairing two units together. Combined with rapid charging capabilities from both AC and solar sources, the AC240 presents itself as a flexible core for a serious off-grid power setup.
Key Features
The Bluetti AC240 comes to the table with several standout specifications. We've isolated a few key features that define its place in the market.
Unprecedented Durability with IP65 Rating
Perhaps the most significant feature of the AC240 is its IP65 rating for water and dust resistance. This is a level of protection not often seen in portable power stations, which are typically sensitive to moisture and particulates. An IP65 rating means the unit is fully protected from dust ingress and can withstand low-pressure water jets from any angle. In practical terms, this allows the AC240 to be used with confidence in the rain, in dusty work environments, or in marine settings where salt spray is a concern.
Highly Expandable and Parallel Power
The AC240 is built on a modular platform that allows for massive growth. The main unit starts with a 1,536Wh LiFePO₄ battery and a continuous AC output of 2,400 watts. For those with greater needs, this capacity can be expanded up to 10,136Wh by connecting up to four B210 expansion batteries. Furthermore, by using a P480A parallel connection box (sold separately), two AC240 units can be linked together. This doubles the AC output to 4,800W and provides a total capacity of up to 20,272Wh when fully expanded with eight B210 batteries. This scalability allows users to tailor the system to their exact needs, from weekend camping to long-term home backup.
Start with the main AC240 unit and add B210 expansion batteries later as your power needs grow. This modular approach can spread out the initial investment while ensuring you have a path for future upgrades.
Rapid and Flexible Recharging
A large battery is only useful if it can be recharged quickly. The AC240 features a powerful 2,200W AC input that enables it to recharge from 0 to 80% in a claimed 45 minutes, minimizing downtime. For off-grid applications, it also supports a very substantial 1,200W maximum solar input. This high solar capacity means users can potentially recharge the unit in just a few hours of good sunlight, providing true energy independence for RVs, cabins, or long-term outdoor use. The unit also functions as a seamless Uninterruptible Power Supply (UPS) with a 15ms switchover time, automatically keeping connected devices running during a power outage.

While the AC240 supports an impressive 1,200W of solar input, solar panels are sold separately. Bluetti's product page notes that some solar panel models may be out of stock, so buyers should confirm availability or plan to use compatible third-party panels to take full advantage of this feature.
Design & Build
The Bluetti AC240 is clearly built with durability as a priority. Its physical design is robust and utilitarian, with integrated handles on the top corners for transport. The dimensions are 16.5 x 11.6 x 16.1 inches, making it a sizable unit. The most critical factor in its physical design is the weight: at 72 pounds (33 kg), it is a very heavy power station. This is not a unit designed for casual portability like a small camping generator; it is a heavy-duty device best moved by two people or with a cart. This weight is the trade-off for its large capacity, high power components, and rugged, weather-resistant construction.
The Bluetti AC240's base weight is 72 pounds. While it features built-in handles, this is significantly heavy for one person to lift and carry over any distance. Buyers should consider this a "transportable" rather than "portable" solution.
Who It's For
Based on its specifications, the Bluetti AC240 is tailored for several key user groups who prioritize durability and high power over low weight. The inclusion of a NEMA TT-30 plug makes it an out-of-the-box solution for RV owners, allowing them to directly power their vehicle's 30-amp service. Likewise, its IP65 rating and salt-corrosion resistance make it an excellent candidate for boaters who need reliable power on the water.
Professionals in construction, agriculture, or field research will find the dust and water resistance invaluable for powering tools and equipment in unpredictable environments. Finally, with its massive expansion potential and fast UPS functionality, it serves as a capable foundation for a home backup system, able to run essential appliances for extended periods during an outage, provided you add the expansion batteries.
FAQ
What does the IP65 rating on the Bluetti AC240 mean?The IP65 rating indicates that the AC240 is completely dust-tight and is protected against low-pressure water jets from any direction. This makes it suitable for use in rain, on a dusty worksite, or in a marine environment without damage to the internal components.
Can the AC240 directly power an RV?Yes. It features a built-in NEMA TT-30 port, which is the standard 30-amp, 120-volt plug used by many RVs. This allows you to plug your RV's shore power cord directly into the power station.
How much can the AC240's capacity be expanded?The base unit has a capacity of 1,536Wh. You can connect up to four Bluetti B210 expansion batteries (sold separately) to increase the total capacity to 10,136Wh.
Is the Bluetti AC240 portable?While it is categorized as a portable power station, it weighs 72 pounds (33 kg). It has built-in handles, but it is best considered "transportable" rather than easily portable. It will likely require two people to move comfortably over any significant distance.
Do I need to buy anything else to get the maximum 4,800W of power?Yes. To achieve the 4,800W output, you must purchase a second AC240 unit and a Bluetti P480A parallel box, which allows you to connect the two units together.
