About this product


Product overview

• 600W continuous output to power a range of household applications
• Pure sinewave output keeps your appliances safe
• 240VAC mains socket to power a product without any additional converters
• 12VDC power direct from your battery using the included alligator clips
• Weighing only 1.9kg, its compact design (295 x 117 x 62mm) allows the inverter to be positioned discretely

Connect mains powered devices with a car, truck or a solar panel

This 12V 600W Pure Sinewave 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.

Power pumps, small power tools and more
This 600W inverter connects to the car battery using the included alligator clips while being designed to mount somewhere out of the way. The inverter can power sensitive electronics up to 600W, such as pumps, small power tools or small refrigerators. 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.

Avoid electrical interferences
This 12V 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 5 out of 5 by from Bought two of these for a Solar Power Project (12v 500w) one for the lighting & media and one for the computers & work bench) So far they have been very good & well behaved. It was a better choice to have two at 600w than one at a higher power output. The price is exceptional especially for a pure sine inverter. Personally I would not even entertain the modified sine inverters now as the later presented several problems with sensitive electronic equipment especially the three mac computers. Overall I am very happy with the product.

Rated 5 out of 5 by from Superb product. I have now purchased two of these inverters for my touring caravan. Very good price. They are operated independently from separate 110Ah deep cycle batteries and supply 220v to both sides of the caravan. The batteries are charged from a 150W/10A solar panel, fixed on the roof, making my caravan totally self-sufficient when on holiday. Highly recommend and willing to give technical advice to anyone considering fitting.

Rated 5 out of 5 by from Pros: Great device, very clean output.. completely eliminated the noise and buzzing my old sine-wave inverter produced. Runs 100% silent on low load, fan comes on with high load after ~15 minutes, it's not too loud unlike my old inverter. Solid build quality and the cables are nice & thick, a good length too. Cons: Uses 6 watts when idle, not great for a 24/7 setup as it would throw away over 1 Kwh of battery per week. Great device, very pleased.

Rated 5 out of 5 by from Quality Piece Of Kit Okay, so I actually purchased one of these many years ago from the Kidderminster store but i thought I'd just put a couple of details down here for any potential purchasers ... it IS a proper, high quality piece of kit and I don't know if they've changed the circuitry since I obtained mine but mine only actually draws 0.8A on "standby" unlike the specs on the item page which state that the standby current is 1.3A (and yes it's the 12v version and not the 24v version mentioned in the downloadable user manual / spec sheet) ... and just in case anyone's wondering how "pure" the Sine Wave actually is ... I've included a screenshot taken from my 8-channel Hantek osciloscope of this particular inverter (don't worry about the bottom left where it says 3.77KV, that's because i had to string 4 10x probes in series to get enough attenuation to fit the trace on screen ;) ) ... Hope this helps someone :)

Rated 5 out of 5 by from Purchased this item for use in my caravan. Absolutely superb. Like it so much that I am buying another one to run on my second leisure battery. Quiet, stable and efficient. Highly recommend.

Rated 5 out of 5 by from The inverter I purchased was well priced accurately described and delivered promptly. I use it to run my flat screen 42" TV via batteries charged from a solar PV system. In operation it is silent.

Hello, If i connect this unit directly to a solar panel, will this work? I am planning to use a solar panel which can produce 12V, 200W DC current. (My AC load will be around 120-150Watts). There will be no battery backup.

Asked by: Russel
Unfortunately, this would not be suitable to run from a solar panel

I want to use this inverter to power a tv/dvd in our motorhome, I want to put a cigarette lighter plug/socket arrangement to power it. Is this ok? What is the loading in amperes when using it for a 20 inch tv/dvd unit?

Asked by: Bryan
Inverters of this size can't be connected to a cigarette lighter plug/socket. I can't tell you the amp draw as no details about wattage have been given for the devices you have.

Hi, I have two HK audio amplifiers and a small mixing desk, together they draw out 250 watt when used near full volume . Do you think this inverter will be sufficient to run my pa on the back of a pick for 2-3 hours during a carnival?

Asked by: Singing Barber
I believe it would run it but I do not know how long for as this depends on the battery you connected it to.

Hi I have a 540WH 36V electric bike battery. The first time I charged it using the inverter it was fine. This time the inverter started making a constant buzzing noise so I have switched it off. Is this noise normal?

Asked by: gricha
Thanks Les,I think you have miss understood. The inverter is connected by clips to a leisure battery then the cycle battery is plugfed into the inverter.

Would I be able to power a Neon Transformer (High Voltage) 8kV 25mA neon power supply with this? Can you charge this unit prior to use, i.e. does it have to be connected to a car battery? Thank you.

Asked by: Artist
This unit does not &quot;charge up&quot; it has no power storage facility of it's own it has to connected to a battery in order to operate. Unfortunately we cannot guarantee suitability for the usage you mention as we have no data whatsoever for such usage.

I use a cpap machine 2.5 amps to help me breathe at night.It supplies a set pressure of air to my facemask. Will this inverter do the job over an 8 hour period from say a 110 leisure battery

Asked by: jonboy
We strongly do not recommend the use of this item or any inverter to provide power to a breathing apparatus.

I need to run a 50 or 100W audio power amplifier off this, although it won't be running at anything near full audio power - probably 5-10W maximum. How long will it last off a 68AH car battery?

Asked by: Jules
Sorry but it is impossible to predict with the info you have provided. You can make a rough calculation Calculate the total amperage draw of the devices you intend to run and divide this into the amp hour capacity of your battery. Remember this is only a guide as performance would be impeded as the battery reaches low charge levels.
