BLUETTI raises the bar with the Apex 300, the power station it presents as the new flagship of its range. Behind the name is a powerful unit: 2,764.8 Wh of capacity, 3,840 W continuous output (7,680 W peak) and, above all, simultaneous 120V and 240V output that brings it closer to a genuine home-backup system. Included in TIME magazine’s Best Inventions of 2025 list and launched during 2025, it targets people who want to power large loads for a long time and expand their installation over time. Expect a price around €1,899 on the European store for the main unit.
This is the kind of product that appeals as much to a curious DIYer as to a family worried about power cuts: a large, modular energy reserve that promises to run a refrigerator as readily as a workshop. I have not tested it; this is an overview based on what BLUETTI highlights, without claiming hands-on experience. Let’s see what this flagship promises.
A station designed to grow with your needs
The Apex 300’s central idea is modularity taken to the extreme. You start with the main unit and its 2,764.8 Wh, then build upward: according to BLUETTI, the system reaches up to 58 kWh of capacity and 11.52 kW of power by combining expansion batteries and additional units. In other words, the same machine can serve as a simple camping backup or become the heart of a complete home-backup system without replacing everything.
The format remains that of a transportable station, with handles and the robust appearance of workshop equipment. BLUETTI also stresses low idle consumption, claimed to be two to three times more efficient than competing products, a detail that matters when the station remains plugged in on standby for weeks.
Announced technical specifications
BLUETTI focuses on power, versatile outputs and battery longevity.
3,840 W output and dual inverter: the station delivers 3,840 W continuously (7,680 W peak) and, thanks to dual-inverter technology, supplies 120V and 240V at the same time. This should run a dryer, water heater or power-hungry tools alongside standard household appliances, where a typical station would struggle.
Second-generation LiFePO4 battery: BLUETTI claims automotive-grade lithium iron phosphate chemistry, rated for around 17 years of service and up to 6,000 cycles before falling to 80% capacity. On paper, it is an energy reserve built to last for a large part of an equipment lifetime.
20 ms UPS switching: during a mains outage, the Apex 300 takes over in under 20 milliseconds, fast enough not to interrupt a computer, internet router or sensitive equipment. The installation is described as plug-and-play.
Fast charging and massive solar input: BLUETTI claims AC charging up to 3,840 W (100% in around 65 minutes under laboratory conditions), up to 19.2 kW solar input through the SolarX 4K controller, and up to 11.52 kW from a 230V generator.
Weather alerts and app: the station is controlled through the BLUETTI app, which shows charge level and consumption and even provides real-time severe-weather alerts to anticipate an announced power cut.

Price and options
The Apex 300 is listed at around €1,899 on the European BLUETTI store for the main unit and starts at around $1,529 to $1,699 in the United States depending on current promotions. Depending on needs, expansion batteries can be added to increase capacity, along with the SolarX 4K solar controller to use the large photovoltaic input. The positioning matches the product’s ambition: this is not simply a portable battery, but the foundation of an expandable energy system. BLUETTI also highlights a potential return on investment in around two years for self-consumption use, a claim to confirm for each use case. Prices vary by market and offer, so it is worth comparing before buying.
Safety, battery and proper use
A station with nearly 2.8 kWh contains a very large lithium battery, which deserves a few honest reminders. BLUETTI highlights its LiFePO4 chemistry, considered more stable than conventional lithium-ion, an intelligent BMS and automotive-grade design. For a backup installation connected to a home’s electrical panel (connection or automatic transfer), however, work by a qualified electrician is strongly recommended and may be necessary depending on the installation: a link to a domestic electrical system should not be improvised. A station of this capacity also far exceeds limits permitted in an aircraft cabin, so it is not intended for air travel. This paragraph is for information only and does not replace the manufacturer’s instructions or applicable regulations; for equipment electrical safety, official information can be found on service-public.fr.
Ecosystem and expandability
The Apex 300 is part of a BLUETTI ecosystem designed to grow: expansion batteries, SolarX 4K solar controller, transfer hubs and the brand’s solar panels can be added as needs change. The idea is appealing on paper: invest in a solid base, then add modules as time and budget allow without changing platform. Compatibility with the in-house app allows everything to be monitored from a smartphone, including the weather alerts. It remains dependent on the manufacturer’s claims and needs confirming in the field.
In conclusion, is this BLUETTI Apex 300 interesting?
On paper, the Apex 300 ticks boxes that place it clearly at the high end: 2,764.8 Wh expandable to 58 kWh, 3,840 W with simultaneous 120/240V output, a LiFePO4 battery claimed to last 17 years, near-instant UPS switching and massive solar charging. For a family wanting truly expandable home backup or a workshop needing power away from the grid, the modular approach is genuinely smart.
Real autonomy with connected devices, ease of installation in a home-backup configuration and the claimed long-term durability still need confirmation in use; a specification sheet cannot settle these points. But the ambition is there and the product has plenty to appeal. I hope to have an opportunity to test it one day.
