When it comes to securing energy independence, choosing the right power station is about matching your specific lifestyle—whether you are preparing for a blackout in the suburbs or heading out for a month-long trip through the Rockies. At BLUETTI, we have developed two powerhouses that often lead the conversation: the Elite 400 and the Apex 300.
While they might look similar on paper, they are designed for very different roles. The Elite 400 is a mobile, high-capacity "all-in-one" unit that fits like a piece of luggage. The Apex 300, on the other hand, is the world's smartest dual-voltage off-grid solution, designed to grow from a portable unit into a massive whole-home backup system.

Performance and Features
Power Delivery: The Muscle Behind the Machine
When it comes to raw power delivery, the models serve two distinct purposes: the Elite 400 is a versatile workhorse, while the Apex 300 is an industrial-grade anchor for your entire home. The Elite 400 offers a continuous 2,600W, which is more than sufficient for most portable applications and can easily handle demanding devices like pumps, air conditioners, and ovens.
In contrast, the Apex 300 delivers a massive 3,840W of continuous power and supports both 120V and 240V dual voltage. This leap in output means the Apex 300 can not only run the same high-draw appliances as the Elite 400 but can simultaneously power a 240V well pump, an electric clothes dryer, or an EV charger—tasks that are beyond the scope of a 120V-only portable unit.
Expandability: Power for Today vs. Power for a Lifetime
Here, the core design philosophies of the two units diverge completely, defining their long-term roles in your energy strategy. The Elite 400 is a powerful, self-contained, all-in-one unit that is not expandable. Its 3,840Wh capacity is fixed, making it ideal for users who need a straightforward, grab-and-go solution.
The Apex 300, on the other hand, is "super scalable." Its base capacity of 2,764.8Wh can be expanded up to an incredible 58kWh by connecting expansion batteries like the B300K or B500K. This transforms the Apex 300 from a simple backup device into a full-fledged energy security system, capable of powering an average Canadian home for several days during an extended outage.
Charging Speed: Less Waiting, More Powering
Both units recharge quickly, but the Apex 300 has a clear advantage. The Elite 400 accepts up to 1,800W from an AC outlet and 1,000W from solar panels, allowing it to reach an 80% charge in just 70 minutes (Dual AC + Solar).
While both units charge rapidly, the Apex 300's ability to accept a massive 3,840W from an AC source allows it to recharge its larger base battery in just 45 minutes to 80%. This remarkable speed ensures minimal downtime, making it ideal for scenarios where the grid is unstable or solar charging windows are brief.
UPS Functionality: Seamless and Secure Backup
Both models offer Uninterruptible Power Supply (UPS) functionality to protect your devices during a power outage. The Elite 400 features a fast switchover time of ≤15ms, which is excellent for keeping computers, refrigerators, and other essentials running without interruption.
The Apex 300 takes this protection to the highest level with an instant 0ms UPS switchover. This seamless transition provides unparalleled security for highly sensitive electronics, guaranteeing they never experience even a flicker of power loss. This is non-negotiable for sensitive home office servers, medical equipment like CPAP machines, or complex aquariums where a momentary reset could be disastrous.
Runtime Comparison Chart: Elite 400 vs. Apex 300
The following estimates are based on typical appliance loads. Note: For refrigerators, these numbers are based on an average hourly draw of 100W; actual runtimes vary as compressors cycle on and off.
| Appliance | Wattage (W) | Elite 400 Runtime (Hours) | Apex 300 Runtime (Hours) |
| Phone Charger | 5 | 167.81 | 94.56 |
| LED Lights | 10 | 134.25 | 78.8 |
| Laptop | 50 | 51.63 | 33.77 |
| Fridge | 100 | 29.18 | 19.7 |
| TV | 150 | 20.34 | 13.91 |
| Coffee Maker | 800 | 4.12 | 2.88 |
| Microwave | 1000 | 3.31 | 2.32 |
| Air Conditioner | 1500 | 2.22 | 1.56 |
