Sleemans BP2400 Portable Power Station – 2,560Wh LiFePO4, 2400W

Name: BP2400 Portable Power Station 2,560Wh / 2,400W LiFePO4 | Sleemans
SKU: BP2400
Price: 899.00 GBP
Availability: InStock

Power wherever the job is – without the noise, fumes or fuel can. The Sleemans BP2400 puts 2560Wh of stored power and 2400W of clean, mains-quality output into a single powerful unit. Keep the fridge cold, the broadband up and the kettle boiling through a winter power cut. Run a market stall, a film set or a campsite all day without a generator droning in the background. It recharges from any UK socket in about two hours and tops up from solar panels or your van. Its LiFePO4 battery is rated for 3,000 cycles, so it will keep earning its place for years. At £899, it gives you more stored power for your money than the big-name brands, and it’s backed by a UK company you can actually phone.

What can a 2000W portable power station run?

A 2000W portable power station runs almost any single household appliance with a UK plug, apart from the biggest heaters and immersion heaters. With 2,400W available, the BP2400 also handles kettles, microwaves and most corded power tools. Runtime depends on capacity. We work it out as 2,560Wh × 85% ÷ the appliance’s watts. The 85% allows for inverter losses, so these are realistic figures rather than best-case ones.

Appliance or device	Typical draw	Approx. runtime on a full BP2400
Phone (one full charge ≈ 15Wh)	–	About 145 charges
Wi-Fi router and fibre box	15W	About 145 hours
Fridge-freezer (average running draw)	60W	About 36 hours
CPAP machine (no humidifier)	40W	About 54 hours
Laptop	60W	About 36 hours
43in LED TV	80W	About 27 hours
Cordless tool battery charger	250W	About 8.7 hours of charging
LED site lighting	200W	About 11 hours
SDS drill	800W	About 2.7 hours of continuous drilling
Microwave	1,000W	About 2.2 hours
Circular saw	1,400W	About 1.6 hours of continuous cutting
2kW kettle	2,000W	About 1.1 hours (roughly 20+ full boils)

Anything rated above 2,400W continuous, such as a 3kW immersion heater, is too much for the BP2400. Look at the WAVE 4200 (4,200W) instead.

Who the BP2400 is for

Builders and trades – silent site power

Run saws, drills, battery chargers and lighting with no petrol can on the van and no exhaust in a stairwell or on a residential street. Unlike a petrol generator, there is no engine to service and nothing to refuel. You recharge it overnight at the yard or from a site supply. See construction site power for site-specific advice.

Events, markets, film crews and mobile catering

The BP2400 is quiet enough to sit under a stall or just off set. It powers a card machine, lights, a coffee grinder or a chest freezer for a full trading day. It also takes recording equipment off the generator, so noise does not ruin a take.

Camping, caravans and campervans

For a long weekend away, one charge covers a 12V cool box, lights, phones, laptops and a hair dryer in short bursts. For lighter trips, the 7kg BP600 is easier to carry.

Home backup in a power cut

Plug the fridge, router, lights and phone chargers into the BP2400 and the essentials carry on through most UK power cuts. If you leave it connected to the mains, it switches to battery in 20ms or less when the grid drops. That is fast enough for most computers and routers to stay on. Read more on home backup power.

Battery safety and lifespan

The BP2400 uses lithium iron phosphate cells, the same chemistry used in stationary home batteries. Compared with the NMC lithium-ion found in phones and older portable power stations, LiFePO4 is far more thermally stable and lasts many more cycles. Built-in battery management adds further safety features: over-current, short-circuit, over-temperature and low-temperature protection.

The battery is rated for 3,000 full cycles. Charged and emptied twice a week, that is more than 25 years of cycling. In practice, calendar age and storage will set the limit before cycle count does.

How to recharge the BP2400

Mains: up to 2,000W from a standard UK socket. An empty-to-full charge takes roughly 1.5 to 2 hours.
Solar panels: up to 400W through the MPPT input (10–60V DC, XT60). With 400W of solar panels in good sun, expect roughly 7 hours or more from empty. UK weather will usually make this longer.
Car or van: from a 12V socket through the same input. Only charge with the engine running so the vehicle battery is not flattened.

BP2400 price vs other 2000W portable power stations

Prices below are published UK prices, including VAT, checked on 14 October 2026. Capacities are the manufacturers’ published figures.

Portable power station	Capacity	Price	£ per kWh

BP2400 FAQs

Can a 2000W power station run a kettle?

Yes, as long as the kettle is rated at 2,000W or less. The BP2400’s 2,400W output handles a 2kW kettle. A full charge gives roughly an hour of kettle time, which is about 20 full boils.

How long will the BP2400 run a fridge?

A typical fridge-freezer averages around 60W once its compressor cycles on and off, so a full BP2400 runs it for about 36 hours.

Can I run a heater from the BP2400?

Yes, but not for long. A 2kW fan heater empties it in about an hour. A 1kW setting lasts about 2 hours. Heated throws and electric blankets (around 60W) are far more efficient and run for well over a day.

Can I use the BP2400 indoors?

Yes. There is no combustion, so there are no fumes and no carbon monoxide. Keep the vents clear and do not cover the unit while it is running.

Can I link two BP2400s together?

No. The BP2400 is a standalone unit and does not support parallel connection. If you need more power or capacity, the WAVE 4200 gives 4,200W and expands to 18,432Wh.

Will it keep my computer on in a power cut?

Plugged into the mains with your equipment connected to it, the BP2400 switches to battery in 20ms or less. That is quick enough for most PCs, routers and NAS drives. For critical servers, use a dedicated online UPS.

How should I store it over winter?

Store it somewhere dry between 0°C and 25°C, at around half charge, and top it up at least every six months. The cells will not charge below 0°C. The BP2400 pauses charging automatically and resumes once the battery warms to 5°C.

Can I connect it to my house wiring?

Only through a proper changeover switch fitted by a qualified electrician. Never back-feed a house through a socket.
