The PWB Series are portable battery power stations: silent, emission-free power with no engine, no fuel and nothing to service. Both use lithium iron phosphate cells rated for 2000 charge cycles, which is the chemistry's main advantage — a petrol inverter generator will need servicing long before an LFP pack is worn out. Sockets are UK BS1363 to IP44, and both models carry USB-A, USB-C at up to 100W and wireless charging pads, so most site and leisure devices connect without an adaptor.
Manufacturer Assurance

PWB1200: 2x230V BS1363 13A IP44, 1x car socket 12V/10A, 2x DC 6514, 3x USB-A, 1x USB-C 100W, 1x wireless charger. PWB2400 doubles the 230V sockets to four and the wireless chargers to two. A 200W solar panel kit is available (KY000A00000).
Key Features
- Silent and emission free — runs indoors, in a vehicle, at an event or overnight where a generator cannot — no exhaust, no noise, no fuel.
- LFP chemistry at 2000 cycles — lithium iron phosphate is more thermally stable and far longer lived than standard lithium-ion.
- UK BS1363 sockets to IP44 — British plugs straight in with no adaptor, and the sockets carry splash protection.
- USB-C at 100W — charges laptops directly at full speed rather than trickling them through an inverter.
- Wireless charging built in — one pad on the PWB1200, two on the PWB2400.
- Solar panel kit available — the 200W kit recharges the pack off-grid, which makes it viable for multi-day use away from mains.
Suitable Applications
The PWB range suits anywhere a generator is impractical: indoor events and exhibitions, film and photography, market stalls and pop-ups, camping and caravanning, mobile working, and emergency backup for routers, lighting and medical devices. On construction sites they suit welfare units, site offices and overnight monitoring equipment. They are not a generator substitute for power tools — check the running and starting watts of any motorised load against the 1200W or 2400W output before relying on it.
How to Use
- Charge fully before first use.
- Check the total wattage of everything you intend to connect against the 1200W or 2400W output.
- Connect loads and switch on the output.
- Monitor the charge display and recharge before the pack is fully depleted where possible.
- Recharge from mains, vehicle or the optional 200W solar kit.
Warning: Check the starting wattage of motorised loads, not just running wattage. A fridge or pump may draw several times its rated power for a moment on start-up and will trip the unit.
Safety Information
- Do not expose the unit to rain or immerse it; the sockets are IP44 splash rated, the unit is not waterproof.
- Do not cover the unit or block its ventilation while charging or discharging.
- Charge only with the supplied charger or the approved solar kit.
- Stop using the pack immediately if it is damaged, swollen or overheating.
- Do not use as a permanent power supply for life-critical medical equipment without a backup.
- Store partially charged in a cool dry place rather than fully flat.
Inspection and Maintenance
LFP packs need little maintenance, but they last longest if they are not routinely run flat and not stored fully discharged. Keep the vents and case clean, check the leads and sockets for damage before use, and cycle the pack occasionally if it is kept purely for emergencies rather than leaving it untouched for months.

Frequently Asked Questions
Q: How long will it run my equipment?
Divide the nominal capacity by the load. The PWB1200 has 1075W nominal, so a 100W load runs about ten hours. Motorised loads with a starting surge need more headroom.
Q: What does LFP mean?
Lithium iron phosphate. More thermally stable and far longer lived than standard lithium-ion — 2000 cycles here, where many consumer packs manage a few hundred.
Q: Can it run power tools?
Light tools within 1200W or 2400W, yes. Anything with a motor draws a starting surge well above its rated power, so check before relying on it. For sustained tool use a generator is the correct equipment.
Q: Can I charge it from solar?
Yes, with the optional 200W solar panel kit (KY000A00000), which makes multi-day off-grid use practical.
