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 and its compact design allows it to be discretely positioned without being in the way. The inverter can power a device up to 150W, such as a laptop, a phone charger or handheld games consoles. It is highly efficient, converting 90% of its energy into output power. It is also fitted with a 2.1A USB socket to charge a wide range of items such as a Smartphone, MP3 player or Tablet. 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. A pure sinewave inverter is used to power sensitive electronic devices such as power motors, power tools, clocks or microwaves.

Rated 5 out of 5 by from Having had a bad experience in the past with an inverter used to charge my laptop from 12V (distorted mouse movement and sound) I was somewhat sceptical about buying a relatively cheap product with a modified sine waveform. I have to say that I am very impressed! The unit is quiet, solid and stays relatively cool even after hours of usage with a 90W laptop adaptor. Top product and if combined with a laptop and mobile internet dongle gives you internet access anywhere, any time, consistently and for my work purposes, it's been a saviour, and incredibly useful where an iPhone screen simply hasn't been big enough!

Rated 5 out of 5 by from Excellent invertor, it does what it says on the packet. A 240v ac suedo-sinewave 150w output which is suitable for most low power mains equipment. I have yet to try it at near full power, but it just sits there without any buzzing or excess heat, in fact the only time it became warm was when it was in the sunshine! I got what I bought and I am very satisfied. I shall now complete my project to make a self sustainable portable mains supply for which I shall be using other Maplin products.

Rated 5 out of 5 by from Really great little inverter, much lighter and more compact than I expected. Have only used for mains phone charger so far, but stayed very cool and no fan noise.

Rated 4 out of 5 by from I race remote control bikes and travel around the country to different race tracks. this product is brilliant. I get to charge my batteries up and also with the USB ports keep my phone charged. even plugged my laptop to give it a charge. Also comes in handy when I am camping. Great product. small and easy to use.

Rated 4 out of 5 by from Excellent product when it works. I bought this unit to charge up my MacBook pro in the car and initially I was very impressed. I plugged it in to a dedicated power outlet in the glove compartment which was rated at 120W and it charged up my laptop with no problems after approximately 1 hour. The next time that i went to use it, i though that i would use a normal cigarette socket in the centre console instead as that was easier to access, but after 15 mins, the unit started to bleep and was too hot to touch. I don't know whether it has to be used in a dedicated power socket or not. but i'll see it there is any difference once this unit cools down.

Rated 5 out of 5 by from Works perfectly if ventilated under heavy load I bought this to power my 13in Macbook Pro, and it does the job fine if not deprived of ventilation to keep cool. Seems very well made.

Can I charge this via UK mains?

Asked by: mooky 7
No, this is not how the item works, this item connects this to a large 12v battery to convert 12v to 240v.

Could I run my lawn mower from this?

Asked by: Smiffy73
This would not be suitable as for a device such as a lawn mower with moving parts would require a Pure Sinewave inverter to operate. We would also need to know the energy requirements of the lawn mower before we could advise.

Is there any way to acquire the schematic for this product or equivalent? I'm building this type of device for my college project and due to the dangers involved with converting 12v DC to 230V AC I would like a safe schematic to work from. Thank you.

Asked by: SMac
Unfortunately, we are unable to provide a schematic for this item. Please note we do offer full support for any products purchased from Maplin.We don't offer any assistance with design projects due to the dangers involved and would urge you seek advice from a professional such as a qualified electrician.

Hi there - whenever this is plugged into the car, it emits 4 long beeps in a row, then a pause, then continues. I don't know what this means. The manual says three long beeps in a row means low car battery - but this is four. Wondering if you can explain?

Asked by: timwthornton
This sounds like a fault with the unit.

Can the inverter be left switched on in standby mode with no power drawn from it? Some inverters are damaged by this, especially if left for a long time.

Asked by: Keith
It is advised to turn the power switch on the inverter off at its power switch when not in use.
