| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 2,764.8 Wh (51.2 V, 54 Ah) |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LiFePO4 |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | 6,000+ cycles to 80% of original capacity |
| ExpansionExtra battery units that add storage to the same system. | Up to 6 × B300K, B300S or B300 batteries per unit |
| Output | |
| AC output (continuous)The power it can deliver all the time. Add up the watts of what you want to run at once and stay below this. | 3,840 W in total, 230 V, 16.7 A max, 50/60 Hz (13 A max per outlet) |
| Power Lifting ModeA mode that runs some heating devices above the normal output rating. Only for devices that allow it. | 7,680 W lifting power |
| USB-APorts for phones, tablets and small devices. | 2 ports, 15 W each (needs the Hub D1, rated 700 W) |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | 2 ports, 100 W max each (needs the Hub D1) |
| Car outletA 12 V socket like the one in a car, for car accessories. | 2 × 12 V/10 A and 24 V/5 A (needs the Hub D1) |
| DC5521A small round DC connector used by routers, cameras and LED lights. | 2 × 12 V/10 A (needs the Hub D1) |
| Charging | |
| AC chargingHow fast it charges from a wall socket. Higher means a shorter wait. | 2,300 W max standard (230 V, 10 A). 3,840 W max, 80% in 45 minutes at 15 to 25 °C, requires the Hub A1 |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | 2 × 1,200 W, 12-60 V DC, 20 A each |
| Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road. | 12 V or 24 V through the car port; alternator charging via the Charger 1 up to 560 W |
| Pass-through chargingWhether it can power devices while it is itself being charged. | Yes |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | 20 ms UPS switchover |
| Housing and warranty | |
| Dimensions (L × W × H)Check the space before you buy, including room around it for airflow and cables. | 525 × 327 × 320 mm (BLUETTI labels them L × W × D) |
| WeightMatters for lifting, wall mounting and moving it. | 38 kg |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Discharging -20 to 40 °C, charging 0 to 40 °C, storage -20 to 40 °C |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | Not stated. BLUETTI's FAQ says the Apex 300 is not waterproof and must be kept dry |
| CertificationsSafety and grid standards the maker says the product meets. | FCC, UL, TELEC, CE, NTC, RCM, LOA ICASA |
| ConnectivityHow you monitor and control it, usually through an app. | Wi-Fi and Bluetooth with the BLUETTI app |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 5 years |
How long will it run your devices?

The estimate assumes 85% of the rated capacity is usable after conversion losses. BLUETTI does not state this figure, so we use a cautious assumption. Real running times vary with temperature, battery age and how each device draws power.
Compatible with
What BLUETTI says this product works with. Anything not listed here is not confirmed.

Rules where you live
The Apex 300 is sold as a power station, but it is built to scale towards home backup. Plugging devices into it is simple almost anywhere. Wiring it into your home circuits (through the optional P050A connection or a bypass) is different: that work should be done by a qualified electrician, and the rules vary by country. See our country guides for the rules, incentives and prices where you live.
Strengths and things to check
Strengths

Worth checking before you buy
- Weighs 38 kg
- USB, car and DC ports need the separate Hub D1
- Fast 3,840 W AC charging needs the separate Hub A1
- Not waterproof, according to BLUETTI
- Not a plug-in home battery: wiring it into the house needs a qualified person

Common questions about BLUETTI Apex 300
What can the Apex 300 run?
BLUETTI rates it at 3,840 W in total across the AC outlets, with 7,680 W lifting power. That covers a fridge, kettle and microwave together. Divide 2,764.8 Wh by the load for a rough running time.
How far can the Apex 300 be expanded?
BLUETTI lists up to 6 B300K, B300S or B300 batteries per unit, and quotes up to 58 kWh and 11.52 kW when several units are combined.
Do I need the Hub D1 and Hub A1?
The USB, car and DC5521 ports need the Hub D1, and the 3,840 W AC charging rate needs the Hub A1. Without them the standard AC input is 2,300 W max.
