• Weighing only 1kg, its compact design prevents it getting in the way

Power home appliances from a car, truck or solar panel
This 12V 150W inverter is a converter that connects to a sealed lead acid (SLA) battery that is usually connected to a car, a truck or a solar panel. The inverter can connect to the battery either through a car accessory plug or by clipping directly to the battery. A mains powered device can then be plugged directly into the inverter’s AC socket. 

Charge your laptop, phone or tablet
This 150W inverter connects to your car battery by using your cars accessory socket. Its compact design allows you to place the inverter out of the way even while in use. The inverter can power a device up to 150W, such as a laptop, a phone or a tablet. It is highly efficient, converting over 85% of its energy into output power. The inverter includes shutdown protection to power down the inverter if the battery power drops below a certain level.

Ideal for more sensitive products
This 12V 150W inverter  is a pure sinewave inverter which produces the same quality energy as a household mains socket, unlike a modified sinewave inverter which produces an approximation. A pure sinewave inverter can power electronics such as motors, power tools or clocks, including products with more sensitive component parts. Unlike a modified sinewave inverter, there will be no electrical interference using a pure sinewave inverter, improving a user’s experience with this type of product.


Rated 4 out of 5 by from Purchased this pure sine wave inverter to recharge my razor, electric toothbrush and laptop while away in my motorhome. I have tried each device with the inverter and it appears to do the job well. The only slight issue is that the lead from the inverter to the 12v plug is quite short hence 4* instead of 5*.

Rated 5 out of 5 by from Works fine but is HUGE I had a modified sine wave inverter and it damaged two toothbrush chargers before I found out that modified sine wave inverters can damage some devices or chargers. Pity because modified sine wave inverters are small. This was the smallest true sine wave inverter I could find and so far, it works fine. Best to stick with the true sine wave inverter.
