| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 3,840 Wh |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LiFePO4 (lithium iron phosphate) |
| 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. | 3,000 cycles to 80%+ capacity |
| ExpansionExtra battery units that add storage to the same system. | Not stated on this page |
| 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. | 2,600 W, 2 AC outlets |
| AC output (surge)A short burst above the continuous rating, for appliances that draw more power when they start. | 5,200 W |
| Power Lifting ModeA mode that runs some heating devices above the normal output rating. Only for devices that allow it. | 3,900 W lifting power |
| USB-APorts for phones, tablets and small devices. | 2 ports, 15 W max each (30 W total) |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | 2 ports, 100 W max |
| Car outletA 12 V socket like the one in a car, for car accessories. | 1 cigarette lighter port, 120 W max |
| Charging | |
| AC chargingHow fast it charges from a wall socket. Higher means a shorter wait. | 2,300 W max, 230 V |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | 1,000 W max, 12-60 V, 20 A max; 6 hours to 100% |
| Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road. | Listed as a charging option (car), along with AC, solar, generator and lead-acid battery |
| 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. | 15 ms or less (UPS) |
| Housing and warranty | |
| Dimensions (L × W × H)Check the space before you buy, including room around it for airflow and cables. | 432 × 288 × 1,042 mm (BLUETTI labels them L × W × D) |
| WeightMatters for lifting, wall mounting and moving it. | About 39 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 -10 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 |
| ConnectivityHow you monitor and control it, usually through an app. | Bluetooth and Wi-Fi app control |
| 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.

Rules where you live
A portable power station is not wired into your home, so it is simple to use almost anywhere. Connecting one to your home circuits to power the house is different, and the rules for that vary by country. See our country guides for the rules, incentives and prices where you live.

Common questions about BLUETTI Elite 400
What can the Elite 400 run?
BLUETTI rates it at 2,600 W continuous, 5,200 W surge and 3,900 W lifting power. That covers a fridge, router and small appliances together. Divide 3,840 Wh by the load for a rough running time.
How fast does the Elite 400 charge?
From the mains it accepts up to 2,300 W, and from solar up to 1,000 W (6 hours to 100%). BLUETTI's headline claim is 0-80% in one hour at 3,300 W with AC and solar together.
Can it power devices while charging?
Yes. BLUETTI lists pass-through charging, so it can recharge and power devices at the same time.
