Why This Is Being Liquidated
This is end-of-line warehouse stock. The units are new, sealed and fully warranted — they are being cleared to free up pallet space ahead of the next model rotation. That is the whole explanation for the price, and it is the only one.
What you get is a serious 256Wh LiFePO4 power station, not a jumped-up power bank. It has a real 300W pure sine wave AC outlet with 600W of surge headroom, meaning it runs mains appliances properly rather than just charging phones. Pure sine wave matters: most units in the budget bracket output a modified square wave that laptops, medical devices and anything with a motor genuinely dislike.
Once the pallet clears, the listing closes. There is no restock at this price and no backorder queue — the stock that exists is the stock that ships.
The Numbers That Matter
Four figures that separate this from the power banks it gets shelved next to.
Six Reasons It Outclasses The Shelf
Everything below is standard, not an upgrade or an add-on.
Instant UPS protection
Leave it inline between the wall and your equipment and it becomes an uninterruptible supply. When the mains drops it takes over in under 20 milliseconds, which is far faster than a router, NAS, desktop or games console can register. Your work session survives, your downloads survive, and nothing has to boot back up.
Five outputs at once
One AC mains socket, one 100W USB-C Power Delivery port, two 18W USB-A fast-charge ports and a 12V/120W car socket, all usable simultaneously. That is a laptop, a phone, a tablet, a camera and a cool box running together off one box, with a combined 300W ceiling across AC and DC.
Two-hour full recharge
Empty to full in roughly two hours from a wall socket, so topping it up is something you do between activities rather than something you plan a day around. It also takes up to 110W of MPPT solar or a 12V/24V car feed, which means it can be refilled entirely off-grid on a long trip.
LiFePO4, not cheap lithium
Lithium iron phosphate chemistry is inherently more thermally stable than the lithium-ion packs used in budget stations, and it holds over 70% of its rated capacity after 4,000 full cycles. That is the difference between an appliance you keep for a decade and a consumable you replace in two years.
30dB and zero fumes
There is no engine, no fuel and no exhaust, so it runs at around 30dB — quieter than a whisper and unnoticeable on a bedside table. That makes it usable in places a petrol generator legally and practically cannot go: indoors, inside a tent, in a campervan or on a balcony in a terraced street.
Full BMS protection
The battery management system guards against overcharge, over-discharge, over-current, overload, short circuit and both high and low temperature operation. It is the layer that means you can leave it plugged in permanently as a backup supply and simply forget about it rather than monitoring it.
Where People Actually Use It
Four scenarios that come up again and again in owner feedback.
Power cuts
Router, laptop and lights stay up. Nothing reboots, nothing is lost.
Camping and festivals
Silent, fumeless power for lights, phones, cameras and a cool box.
Van and road trips
Recharges from the 12V socket while driving, runs a small fridge at camp.
Work off-grid
Allotments, garages, market stalls and photo shoots with no socket in reach.
Exactly what you want in an outage
It has USB-C, two USB-A, a car socket and a proper mains outlet, so it charges plenty of things at once. Surprisingly light for what it holds, which means it isn't a burden to take camping or to an event where you're away from a socket for a while.
Ran the router and two laptops through a cut last month without either machine noticing. That was the whole reason I bought it.
Well built and genuinely intuitive
Solidly constructed, not too heavy, and the built-in handle makes it easy to move around. USB ports plus a 12V socket plus a standard outlet make it very good value for what it does.
No manual needed — I had it powering things within a couple of minutes of unboxing. The display tells you input, output and remaining percentage at a glance.
Quiet enough to forget it's on
The thing I did not expect was how silent it is. It sits under the desk running the router and monitors and I genuinely cannot hear it. Compared to the petrol generator I used to drag out, it's a different world.
Recharge speed is the other surprise. Plugged in after breakfast, back to full before lunch.
Against A Petrol Generator
The comparison most buyers run before they order. Here it is up front.
Why Pure Sine Wave Matters
Most power stations in the budget bracket cut a corner you cannot see on the box: they output a modified square wave instead of a true sine wave. It works for a kettle. It does not work well for laptops, medical equipment, anything with a motor, or sensitive electronics — those either refuse to run, run hot, or quietly degrade.
This unit outputs a genuine pure sine wave, the same shape as the mains supply in the wall. That is what makes it safe to put a CPAP machine, a laptop or a camera charger on it and simply not think about it. It is also the reason the 600W surge rating is useful rather than theoretical — a fridge compressor spiking on startup gets clean power to spike into.
The front display shows live input wattage, output wattage and remaining percentage, so you always know exactly what you are drawing and how long you have left.

⚠️ Buying from the clearance stock — what to know
Because this model is being liquidated, lookalike units circulate on marketplace listings at similar prices. They typically use lithium-ion rather than LiFePO4 cells, output a modified square wave instead of pure sine, have no true UPS function at all, and ship without warranty documentation of any kind.
Every unit released through this clearance is original sealed stock with the full 6-year manufacturer warranty, dispatched from the warehouse holding the remaining pallet. If it does not perform as described, the 30-day money-back guarantee applies with no conditions attached.
