Why This Batch Is Being Cleared
This is end-of-line warehouse stock. The next generation chassis has already been announced, which means every remaining unit of this model has to move before the incoming pallets arrive — and warehouse space costs more per week than the margin on these boxes is worth.
Nothing has been stripped out, refurbished or downgraded. These are sealed, factory-new units with the full battery management system, the full 1800W inverter and the full warranty. They are simply the last of a production run that is finished. When the count hits zero, this page comes down — there is no reorder scheduled.
Power That Doesn't Ask Permission
Most people discover how fragile mains power is at the worst possible moment. The wind picks up, the lights flicker twice, and suddenly the router is dead, the freezer is quietly defrosting, and the only light in the house is a phone screen at 14%. It is not a disaster — it is just a long, cold, irritating evening that could have been avoided for the price of a takeaway.
This unit exists to make that evening a non-event. 1024Wh of automotive-grade LiFePO₄ storage sits in a box roughly the size of a small cool box, holding its charge on a shelf for months at a time. When the grid drops, it takes over in ten milliseconds — faster than a desktop PC can register a fault, fast enough that a NAS drive never even flags an unclean shutdown.
And because it pushes a genuine 1800W of continuous output, it is not limited to phones and fairy lights. A kettle. A microwave. A fan heater. A chest freezer. A full home-office setup with two monitors and a dock. The things you actually miss when the power goes — those are the things it was built to carry.
The Difference
Four things separate a serious power station from the battery bricks that tap out the moment you plug in anything with a heating element.
Five Ports. Everything Plugs In
Two full mains sockets carry the heavy work — 1800W continuous between them, with a 3600W surge headroom that absorbs the brutal start-up spike a fridge compressor or a pod coffee machine throws at it. That surge margin is the difference between a machine that runs your appliances and one that trips out and blinks a fault code at you.
Alongside them sit a 100W USB-C port, a 30W USB-C and an 18W USB-A. The 100W port charges a modern laptop at full speed, not the trickle you get from a car adapter — so a working day away from a desk is genuinely possible rather than theoretical.
Boost mode expands headroom to 2400W for high-draw appliances that would otherwise overload a unit of this size. In practice that means you stop planning around the power station and start just plugging things in.
Three Ways To Fill It, One Of Them Free
From a standard wall socket it goes 0–80% in 45 minutes and to a full charge in around an hour. That is fast enough to top up over a lunch break, or to bring a flat unit back to useful before you leave the house — which matters far more in real life than a headline capacity figure does.
Clip on a solar panel and it recharges in roughly 1,8 hours in good conditions, costing you nothing at all. Off-grid, that turns the unit from a finite tank into something closer to a small self-sustaining supply: you draw down through the evening and the sun puts it back the following day.
There is also alternator charging from a vehicle, which refills it in about the same 1,8 hours while you drive. Between the three inputs, there is almost no realistic scenario where you end up stranded with a flat unit and no route back.
Ten Milliseconds. Nothing Notices
A standby generator is useless if it takes thirty seconds to come alive, because by then every sensitive device in the house has already gone dark. This unit sits inline as a true UPS: when mains power drops, it takes over in under ten milliseconds. Desktops keep running. Routers stay online. NAS drives never see an unclean shutdown, which is the single most common way people lose data at home.
For anyone working from home, that is the difference between a five-hour outage costing you nothing and costing you an afternoon of unsaved work. For anyone running a freezer, a fish tank, a CPAP machine or a medical fridge, it is the difference between an inconvenience and a genuine problem.
The onboard battery management system handles the rest — temperature, cell balancing, overload protection and short-circuit cut-off — so the unit looks after itself while it sits on standby for months on end.
Built For Every Scenario
One box, four completely different lives. Buyers use it in ways the spec sheet never mentions.

What One Charge Actually Runs
Capacity figures mean nothing until you translate them into hours of the things you care about. Here is what 1024Wh looks like in practice, measured at realistic draw rates rather than best-case laboratory conditions.
Lights
A 10W camping light or LED lamp runs for well over two full days on a single charge.
Mini fridge
A 60W compressor fridge or cool box runs the best part of a full day and night.
Projector
A 65W projector or TV setup — enough for an entire weekend of evening viewing.
Heated blanket
A 120W electric blanket through the coldest nights, twice over.

Why Installers Recommend It
⚠️ Beware of counterfeit battery packs
The market is flooded with clones that advertise 1024Wh and deliver a fraction of it, using recycled cells with no battery management system. Those units are not just disappointing — they are a genuine fire risk, and there is no warranty behind them when they fail.
Every unit sold here is sealed, factory-new stock from the original production run, with the full battery management system, the genuine LiFePO₄ cell pack and the manufacturer's warranty intact. Nothing is refurbished, repackaged or grey-imported.
Because this is a liquidation batch, we cannot restock once the current allocation clears. If the page is still live, stock is still available — that is the only guarantee we can offer on timing.
