RETURN AND REFUND POLICY

A compact LiFePO4 power station in two sizes: a 400 W model with 192 Wh of storage weighing 2.25 kg, and a 500 W model with 461 Wh weighing 3.65 kg. Both give pure sine wave AC output, which matters for laptops and anything with a motor or sensitive electronics, along with USB, Type-C, and DC sockets. They charge from mains, a car socket, or a solar panel, and each version can be bought with a charger or bundled with a panel.

  • Light at 2.25 kg or 3.65 kg
  • Charges from mains, car, or solar
  • USB, Type-C, and DC5521 outputs
  • Display screen
  • Replaceable battery

Product Highlights

Pure Sine Wave Matters

Cheaper units output a modified square wave, which makes some laptop chargers, fans, and medical devices buzz, run hot, or refuse to work. This one produces a clean sine wave like a wall socket.

LiFePO4, Not Standard Lithium

Lithium iron phosphate handles far more charge cycles and runs cooler than the lithium ion used in most budget power banks, so it stays useful for years rather than seasons.

Genuinely Portable

At 2.25 kg for the 400 W and 3.65 kg for the 500 W, these are light enough to carry in one hand to a campsite, a market stall, or a power cut.

Three Ways to Fill It

Mains charger, car socket, or solar panel. Choosing the solar bundle means you can keep going indefinitely off-grid rather than rationing what you left home with.

Battery Can Be Replaced

The battery is replaceable, so the unit does not become waste the day the cells finally wear out.

Important Information

  • Check the AC output voltage before ordering. The manufacturer's description lists 220 V output with a universal socket, while a separate data field says 220 V / 110 V. If you are running 110 V appliances on North American plugs, contact us first and we will confirm which configuration ships, because the wrong one will not run your equipment.
  • The model and bundle are combined into the colour option. Check whether your selection is the 400 W or 500 W unit, and whether it includes the charger or the solar panel.
  • One data field lists the capacity as 192 Wh and another as 461 Wh. These are the two different models: 192 Wh for the 400 W, 461 Wh for the 500 W.
  • Solar panel specifications are not listed for the bundled options. Contact us if you need the panel's wattage before ordering.
  • Capacity in watt-hours tells you runtime. A 461 Wh unit will run a 50 W device for roughly eight hours, less as the load rises.
  • Charge and store the unit in a dry, ventilated place away from direct heat.
  • Do not run appliances that draw more than the rated output. Kettles, heaters, and hair dryers are well beyond what a 500 W unit can supply.

Frequently Asked Questions

What is the difference between the two models?

The 400 W has 192 Wh of storage and weighs 2.25 kg. The 500 W has 461 Wh and weighs 3.65 kg.

What voltage does it output?

The manufacturer lists 220 V with a universal socket, and a separate field mentions 110 V. Contact us before ordering so we can confirm which you will receive.

Can I charge it with solar?

Yes. Solar charging input is 300 W to 500 W, and a panel bundle is available.

Why does pure sine wave matter?

It matches mains electricity, so laptops, motors, and sensitive electronics run properly rather than buzzing or overheating.

What can I plug into it?

An AC socket, two USB ports, Type-C, and two DC5521 outputs.

Can the battery be replaced?

Yes, the battery is replaceable.

Is it certified?

The supplier lists CE, RoHS, and UL.
