About this product

Overview

  • 1000W continuous output
  • Modified sinewave output to power chargers, heaters and air conditioners
  • Two 240VAC mains sockets powers products without additional converters

Product overview

• 1000W continuous output
• Modified sinewave output to power chargers, heaters and air conditioners
• Two 240VAC mains sockets to power products without additional converters
• 12VDC power from two alligator clips connected directly to the battery
• Weighing in at 4.15kg, the rugged metal design (300 x 198 x 80 mm) is mountable so that it can be positioned without becoming an obstruction
• Shutdown protection against power overload

Connect your home appliances to a car, truck or solar panel
This Maplin 12V 1000W 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 12V 1000W 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 range of appliances at once
This Maplin 12V 1000W Inverter connects to the car battery directly with alligator clips and can be mounted in a suitable position without being obstructive. The 1000W inverter can power several products at the same time up to a combined maximum of 1000W, such as a television, an induction hob or a laptop, making this inverter ideal in a camper or while out camping. 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.

Charge your laptop or printer
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 4 out of 5 by from Back-up Power for freezer I bought this to provide back-up power to my 2 upright freezers using a car battery in case of failure in the mains supply. I tried two 600W inverters first but they would not take the continuous load on either freezer, let alone the peak load when the compressors switches on. This one seems to run at least one freezer no problem but I sense it will struggle with 2 if they both try to run their compressors at the same time. Hope I never have to find out! Only gripe is that it comes with ring battery connectors, not crocodile clips like the 600w inverters. I now have to buy adapters for my battery terminals, which Maplin don't sell.

Rated 5 out of 5 by from bought one of these last year ,very good bit of kit ,i have wired it directly to 2 110 amp leisure batterys on my motorhome so i can run a laptop, freesat box etc ,it has never run down my batteries even when using the laptop for 2-3 hrs. The remote control is worth every penny as it saves time having to switch the invertor off at the unit.

Rated 4 out of 5 by from Caution Modified Sine Wave inverters produce square wave outputs which have a poor power factor due to the current and voltage not being in phase with each other. This waveform can damage some electric motors, such as compressors on fridges and freezers, and will be expensive to repair. That's why Pure Sine wave inverters are produced, but they are more expensive. Modified sine wave inverters are ok for use with electrical devices that use an external switch mode power module, such as are provided with most lap top PC's and some TV's.

Rated 5 out of 5 by from Good inverter, perfect for emergency power This is an excellent inverter! I bought it to power my home office in the event of a power failure, following ex-hurricane Ophelia. When connected to my Nissan Leaf, it powers both of my fridges (one with dual compressors), two desktop PC's, two desk lamps and even charges my mobile! I haven't measured the power drain, but it must be near 1 kilowatt as the car supplies power for about 20 hours, before the battery gets too low. After a couple of hours the inverter feels quite warm, but the fan is generally off and only kicks in for a few seconds (with a brief flash of the red LED) when one of the fridge compressors start up. I am highly impressed so far and would recommend this unit!

Rated 5 out of 5 by from Impressive piece of equipment Very impressed with this. I use it in my motorhome, running off of 2 110 amp hour leisure batteries, to power the TV and my wife's hair-dryer. (V. important!) It's slightly smaller that my previous unit, very quiet running and will power the hair-dryer on full power setting, something my previous unit, allegedly 1000w, would only run at half power. A previous reviewer complained that the leads didn't have crocodile clips at the ends. I hope he didn't change the ring terminals because if you're handling 80 amps plus in the input circuit, you really do need a good connection with the battery. Only disconcerting issue is when you switch the unit on, all three lights, normal, heat overload and power overload, light up and there's no output, but after three seconds, the overload lights go out and you have output. In all, it does what it says on the box, if not the tin!

Rated 5 out of 5 by from Keeps my office going Good solid unit. With a 100Ah battery it powers my laptop, desk VoIP phone, router and wireless extender during 2-hour power cuts. Nice long leads so you can put the battery somewhere safe. Ring terminals don't fit the battery posts, but cut them off and replaced with WD1R clip-ons.

Does the car Engine need to be running when using this in a vans 12v leisure battery?

Asked by: Jjwren56
It would depend on how the accessory socket is wired. As long as power can be drawn from the battery without the engine then no, this should still work. If the accessory socket is linked to the engine and isolated when the engine is off, then the inverter would stop working with the engine off.

Can you run the full current through one socket? I ask as photo shows two 240v sockets. May be there is some circiut that splits the current between the two sockets. thank you. 

Asked by: knockmzn
You can run the full current through one socket. however if you want to use both sockets at a lower current that would be possible too

On testing the fitted unit the overload light comes on very very briefly then just the green normal light stays on. 240 volt power appears to be produced. After 5 to 7 seconds a high pitched continuous beep starts and carries on till cut off occurs. Help
