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?
The RINVM1000 inverter connects directly to the car battery with battery clips. The screw mounts allow you to position this inverter discretely so that it is accessible without being obstructive. The inverter can power a device up to 1000W, such as a laptop, a television or even a kettle. This inverter is fitted with two mains sockets allowing you to operate two devices at the same time. It is highly efficient, converting 85% of its energy into output power. It is fitted with a 2A USB socket to charge a wide range of items such as smartphones, MP3 players or tablets while still keeping the mains socket available to power an additional item. The inverter has 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 A71JW. A pure sinewave inverter is used to power sensitive electronic devices such as power motors, power tools, clocks or microwaves.

Is it re-chargeable? If so, through the mains plug? How long will it maintain the use of a laptop for watching movies? 

Asked by: robs
You connect this item to a 12v battery and this powers the item.

Will this item power a portable electric cooler box mid to large size and if so for approximately how long? Or, over how long a period will this item power something needing 900w of power to run?

Asked by: robs
The will power items up to 1000W but how long it will run for will depend entirely on the size of the battery you connect it to.

Could I use this in my car to charge a powered wheelchair

Asked by: Grumpy
This would vary with how many watts the item needs if its under 1000 this item should work fine.
