AC300 vs Apex 300: Portable Power Station Comparison

As we move toward a more sustainable and energy-efficient future, the demand for portable power solutions is growing rapidly. Whether for home backup, RVs, or off-grid living, BLUETTI has been at the forefront, offering innovative products to meet a wide range of energy needs. Two standout products in this category are the Apex 300 and AC300, both designed to provide reliable power where and when you need it most.

However, the Apex 300 is BLUETTI's latest iteration, offering several improvements over its predecessor, the AC300, which was introduced two years ago. As energy requirements evolve and more people seek compact, all-in-one storage solutions, it’s essential to ask: How does the new Apex 300 improve upon previous models like the AC300?

In this blog, we’ll break down the key differences between the Apex 300 and the AC300 to help you decide which one best fits your needs.

Why the Apex 300 is the Next Generation of Energy Storage

The Apex 300 brings a number of exciting upgrades compared to the older AC300 model, marking a significant leap forward in terms of design, efficiency, and scalability. Here’s why the Apex 300 represents the next generation of portable energy storage:

All-in-One Design

One of the most significant changes with the Apex 300 is its all-in-one design, combining the battery and inverter in a single, compact unit. The AC300, on the other hand, requires a separate battery (the B300K) and inverter, which means a bulkier setup with more complex installation. The Apex 300 reduces that complexity, offering a sleek and portable unit that’s easier to transport and integrate into a variety of setups.

Dual Voltage Compatibility

Another upgrade is the dual voltage feature. The Apex 300 can deliver both 120V and 240V output, giving it more flexibility and making it compatible with a broader range of devices, from small appliances to high-powered systems like electric water heaters or induction cooktops. The single unit of AC300 is limited to 120V, which makes it less versatile for users who need to power more demanding appliances or setups.

Enhanced Scalability

When it comes to storage capacity, the Apex 300 is a powerhouse. While combining 2 AC300 units in parallel via a P030A fusion box can scale up to 22118.4Wh by connecting up to 8 B300 batteries, connecting 3 Apex300 units via Hub A1 Parallel Box can scale to a much larger 58 kWh using 18 B300K batteries. This makes the Apex 300 ideal for users with higher energy demands, whether for long-term home backup, RV living, or off-grid setups. More capacity means longer periods of uninterrupted power, ensuring you're ready for whatever situation arises.

Modernized Efficiency

The Apex 300 also outperforms the AC300 in terms of efficiency. With an output capacity of 3840W, compared to the 3000W output of the AC300, the Apex 300 delivers more power in less time. Whether you're charging devices or running larger appliances, the Apex 300 gets the job done faster and more efficiently. Plus, the Apex 300 has a faster charging time, making it a more modern and user-friendly option.

Comparison: Apex 300 vs. AC300 in Different Scenarios

To better understand which model is right for you, let’s dive into some real-world scenarios where these two portable power solutions could be used: household energy storage, RV and outdoor living, and off-grid living.

Household Energy Storage

For most homeowners looking for backup power, compactness, and efficiency are key factors. This is where the Apex 300 shines.

Apex 300

With its compact size and lightweight design, it’s easy to integrate into your home without taking up much space. The Apex 300 can store 19.4 kWh of energy when paired with six B300K batteries, which is enough to power essential household appliances like refrigerators, heaters, washing machines, and lighting for over a day during an outage. Additionally, its dual voltage compatibility makes it suitable for powering both 120V devices (like small electronics) and 240V appliances (like electric water heaters and induction cooktops). It's a versatile solution for modern homes that need a reliable backup system.

AC300

The AC300 is still an excellent choice for home backup, but its bulkier design and reliance on a separate battery make it less streamlined than the Apex 300. It can only be paired with up to 8 B300 batteries (22kWh), which means its energy storage capacity is more limited. While it’s still capable of powering most household essentials, it doesn’t have the same flexibility or efficiency as the Apex 300. For higher-powered appliances, the AC300 is capable of handling them with the use of the P030A fusion box, allowing it to support 240V Split Phase Bonding for appliances like electric heaters and heat pumps.

RV and Outdoor Living

When it comes to RV living or outdoor activities, portability, ease of use, and the ability to power both small and large appliances are key.

Apex 300

The Apex 300 is specifically designed with portability in mind. It’s a compact and lightweight power station that can easily be moved and set up in an RV or taken on a camping trip. Thanks to its dual voltage output, you can power 120V RV appliances (like lights, fans, and coffee makers) as well as 240V heavy-duty devices (such as electric grills or space heaters). With a scalable storage solution, the Apex 300 can provide continuous power for several days, especially when paired with BLUETTI solar panels for recharging.

AC300

While the AC300 is still a powerful option for powering RVs and outdoor living setups, its bulkier design and separate inverter and battery setup make it less portable and convenient than the Apex 300. While it offers powerful outputs and has RV-ready ports like a TT-30 30A outlet and 12V/30A DC RV port, its bulkier design makes it less suited for outdoor or RV applications where space and weight are a concern. Additionally, the AC300’s limited portability makes it harder to use for on-the-go energy needs.

Off-Grid Living and Solar Integration

Apex 300

For off-grid living, the Apex 300 is a fantastic choice. It supports multiple units for even greater scalability, allowing up to three Apex 300 units to deliver a combined output of 11.52 kW, which is more than enough to power larger homes, workshops, or cabins. With the ability to integrate up to 18 B300K batteries, the Apex 300 provides an impressive 58 kWh of total energy, making it a reliable solution for long-term off-grid power. Its dual-voltage support makes it even more versatile, capable of powering both small lights and high-powered appliances like induction stoves and water heaters, which are essential for off-grid living.

AC300

Although the AC300 can be used for off-grid scenarios, it is more limited in terms of scalability and flexibility compared to the Apex 300. Combining 2 AC300 units in parallel via a P030A fusion box, the AC300’s maximum capacity is 22.1 kWh, achieved with 8 B300K batteries, which can handle medium-sized off-grid setups. However, its higher capacity doesn’t allow for the same level of expansion as the Apex 300, limiting its potential for larger homes or long-term off-grid applications. While the AC300 is solar-compatible, it doesn’t offer the same portability and solar efficiency as the Apex 300, which is designed specifically to provide seamless off-grid power in remote locations.

Price and Value Comparison

When it comes to choosing between the AC300 and Apex 300, the price is definitely an important consideration. While the AC300 may seem like a more budget-friendly option at first glance, it's important to think about the long-term value. Sure, you might save some upfront costs, but the AC300's older technology and bulkier design may not be the best investment for the future.

The Apex 300, on the other hand, offers a more modern approach with its compact, all-in-one design that reduces both physical space and complexity. With a higher output of 3840W and the ability to scale up to 19.4 kWh with 6 B300K batteries, the Apex 300 is an investment that will serve users for a longer duration. The dual-voltage feature further enhances its versatility, making it suitable for a wider range of appliances.

Considering the energy savings over time, the Apex 300 offers a two-year expected payback period through peak-load-shifting strategies and a reduction in electricity costs. This makes the Apex 300 a more valuable option for long-term energy solutions, providing both cost efficiency and flexibility.
