What is an inverter?
An 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. Inverters vary in capacity and can power devices of up to a specific wattage. Inverters can be split into two categories: pure sinewave and modified sinewave.

What makes this inverter unique?
This inverter connects to the car battery through the car accessory socket or by connecting directly to the battery using alligator clips. Its compact design allows it to be discretely positioned without being in the way. The inverter can power a device up to 300W, such as a laptop, a Tablet charger or a handheld games console while still keeping the mains socket available to power an additional item such as a battery charger. The inverter includes shutdown protection to power down the inverter if the battery power drops below a certain level.

What is the difference between pure sinewave and modified sinewave?
All household mains sockets output a sinewave along the cable to transfer power from the source, such as the battery or plug to the product that is plugged in. This product is a modified sinewave inverter which produces a stepped approximation of a pure sinewave inverter which makes it easier to produce. A modified sinewave inverter can power devices such as laptops, printers and chargers, although some items may pick up interference from the inverter. A solution for this is to upgrade to a pure sinewave inverter, such as these. A pure sinewave inverter is used to power sensitive electronic devices such as power motors, power tools, clocks or microwaves.

Will this unit be suitable to power 5 LED 240 volt bulbs rated at 6Watts each for short periods from a 120Ah battery which is regularly kept fully charged.

Asked by: Philm
Yes this should be fine to use.

will this safely run a macbook pro without cutting out?

Asked by: Anonymous
It would depend on what the wattage draw of your mac book is if its below 300w then yes.
