About this product


  • 1000W continuous output
  • Pure sinewave output is ideal for powering TVs, digital microwaves, fridges and laptops
  • 240VAC mains socket to power a product without additional converters

Product overview

• 1000W continuous output 
• Pure sinewave output is ideal for powering TVs, digital microwaves, fridges and laptops
• 240VAC mains socket to power a product without additional converters
• 12VDC power directly from the battery using the included alligator clips
• Weighing 4.6kg, its mountable metal design (360 x 195 x 80mm) can be positioned out of the way

Connect your home devices to a truck, car or solar panel
This 12V 1000W inverter is a converter that connects to a sealed lead acid (SLA) battery that is often connected to a car, a truck or a solar panel. The 12V 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. 

Power a fridge, hair dryer and more
This 12V 1000W inverter connects directly to the car power using the included alligator clips. Its metallic frame is mountable within your vehicle allowing you to position the inverter unobtrusively. The inverter can power a device – even with sensitive electronics – up to 1000W in power, such as a refrigerator, a hair dryer or a halogen oven. 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.

Power more sensitive appliances

This 12V 1000W 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 1 out of 5 by from I bought this to use with power tools, as I read that modified sine wave inverters don't work well with power tools. It worked well with a 400W jigsaw and a 500W drill, but interestingly only at full power, if I tried the speed knob on the jigsaw or depressed the trigger gently on the drill the inverter sensed an overload and shut down. It worked very well with a 1000W reciprocating saw as well. It did not work with a 700W microwave oven, then I found out that the over actually draws 1200W, but intermittently, so on average it consumes 700W. However, the inverter failed after a few months, while charging a dustbuster, drawing maybe 5W. I'll see how the warranty works out.

Rated 4 out of 5 by from A good unit These are good units and do the job they are designed for. But beware, some loads require a high peak inrush current at start up which can trip the overload circuit. My unit will run my absorption type fridge and separate freezer, but the unit trips out when the fridge or freezer thermostat initially cuts in. The unit needs a soft start circuit on its input to dampen the initial peak inrush current. I've tried various circuits externally, but it really needs a longer delay on the internal trip circuit to hold off the trip until the surge has passed. The output waveform is a nice clean sinewave at 50Hz and 250 volts. I've been running all my TV's, radios, computers, printers and some light fittings around my house from this unit for over a year with no problems, but not my fridge or freezer.

Rated 4 out of 5 by from A 800w microwave is the MICROWAVE power. The INPUT power is about 1300w!! So you need a 1500w inverter, not a 1000w. Pure sinewave is important for a lot of digital equipment. This is a vast improvement over a modified sine wave version.

Rated 5 out of 5 by from Good quality and value This is a well built piece of kit. We bought it for our motorhome to run my wife's GHDs which it did. The only problem was that it wouldn't run the 800w microwave. We found that the microwave actually needed 1300w input which exceeded the capacity unfortunately...........only just though as this machine will run at 1200w for 10mins.

Can you run a 620 watt Henry Hoover from this inverter for cleaning a coach

Asked by: Stevie
Yes, I am pleased to advise this product will do exactly as you require.

Does this work on a 24v input as well? Looking at the machine markings - and the downloads - it looks like you can put 24v into it. Is this the case, or can it definitely only run on a 12v input? 

Asked by: Peter
No, this is purely a 12v unit.

What size and type of battery is required

Asked by: Chrisg
This would depend on the application this will be used, it is designed to be ran from a car battery, with a constant input from the alternator, but could be used in a large solar application as well.

I believe the 230Vac output is floating and not tied to a chassis/earth reference. Is it possible to connect one side of output (i.e..neutral on the 13amp socket) to the chassis/earth to provide a supply that is not floating to suit load connected.

Hi can you please tell me if this inverter will power ghd hair straighteners as modified sine wave products will not. Thanks.

Asked by: Sue P
If they are less than 1000W yes.

Hi I'm trying to work out whether a pure sinewave inverter like this or a modified sinewave inverter is possible to power an 850w baby bottle preparation machine (tommee tippee perfect prep)? I imagine the only moving part is a tiny pump perhaps

Asked by: Engfuser83
An update for those interested, I purchased the modified sinewave 1000W version to try out as it was all my local maplins had in stock and good news, it functions fine. Of course I have only tried it a couple of times so no long term data to give.

Hi I have recently bought one of these inverters. When I don't have anything plunged into it all 3 lights are flashing power temp and overload is this normal. Also it shuts down when I try to use a 800 watt microwave cooker.
