A compact, no-fuss 400W European inverter that connects straight to your 24V battery or cigarette lighter socket — ready to power small UK/EU appliances anywhere, right out of the box.
The AIMS Power PUK40024230W is a 400-watt modified sine wave power inverter designed for European and UK 230V/50Hz systems, converting 24V DC battery power into 230V AC electricity through a Type G (UK 3-prong) outlet. It ships with a cigarette lighter connection cable, so you can be up and running immediately from a 24V vehicle without any wiring. Compact, lightweight, and built into an aluminum housing, it's an ideal solution for powering small appliances, tools, and devices in trucks, heavy equipment, off-grid cabins, and solar battery systems. Note: This is a European/UK 230V model — it will not work with 120V US power systems.
The PUK40024230W keeps it simple — the cables you need are in the box, protections are built in, and the unit is ready to power small European loads from a 24V system immediately.
400 watts continuous handles small appliances, chargers, fans, and light tools — with an 800-watt surge to manage the startup draw of small motors and compressors.
Comes with a cigarette lighter connection cable with a built-in fuse — plug straight into a 24V vehicle socket and start powering devices immediately, no additional wiring required.
Full-load efficiency of 90% and 1/3-load efficiency of 95% means minimal energy is wasted — your battery lasts longer and delivers more usable runtime at light and heavy loads alike.

No. The PUK40024230W outputs 220/230V AC at 50Hz and uses a Type G (UK 3-prong) plug. It is designed exclusively for UK, European, and other 230V/50Hz regions. It will not power US 120V/60Hz equipment.
No — the PUK40024230W is designed specifically for 24V DC input (operating range 20–30V). It will not function on a 12V battery. If you need a 230V UK inverter for a 12V system, AIMS Power offers the PUK40012230W, which is the 12V variant of this same model. Confirm your battery bank or vehicle voltage before purchasing.
No. While the inverter itself supports up to 400W continuous, the cigarette lighter cable is limited by the vehicle socket's wiring capacity — typically 180W maximum. For loads between 180W and 400W, you must connect directly to the battery using appropriately sized DC cables and an inline fuse. The cigarette lighter cable is convenient for light loads; for heavier loads, a direct battery connection is required.
The PUK40024230W is well-suited for small appliances drawing up to 400W — such as laptops, phone and device chargers, small fans, LED lighting, small coffee makers, and light hand tools. Modified sine wave output is compatible with most resistive loads and standard motors. Sensitive electronics like medical equipment, certain audio gear, or variable-speed motor controllers may not perform optimally with modified sine wave power.
Yes — heavy trucks and many commercial vehicles run 24V electrical systems, making this inverter a natural fit. The unit operates within the 20–30V DC range that covers standard 24V vehicle batteries (typically 24–28V when charged), and the cigarette lighter cable lets you connect without any modifications. For sustained or heavier loads, direct battery connection is recommended.
The green LED confirms the inverter is powered on and operating normally. The red LED warns of a fault condition — such as overtemperature, overload, or output short circuit. If the red LED activates, remove or reduce the load, allow the unit to cool if needed, and switch the unit off and back on to reset.
AIMS Power covers this inverter with a 1-year warranty on parts and labor from the date of purchase, along with one year of free technical support. As an authorized AIMS Power dealer, TrueStead Supply fully supports your warranty.
