Product overview

• 100W continuous output with a peak output of 120W to power a range of common household appliances
• Modified sinewave output is ideal for use with chargers, heaters and air conditioners
• AC240V output to power a product without additional converters
• DC12V plug socket to allow a simple connection into a car accessory socket
• Weighs only 123g and its compact design (186mm x 189mm x 210mm ) prevents it getting in the way
• 2A USB connector to charge an additional device such as a smartphone or tablet

Power a range of home appliances
This 12V 100W 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. 

Attaches to the foot well of your car
This inverter connects to the car battery through the car chassis socket and its compact design allows it to be mounted easily in the foot well. The attached coiled cable will allow it to be secured without becoming tangled. The inverter can power a device up to 100W, such as a laptop, a phone charger or a handheld games console. It is highly efficient, converting 90% of its energy supply into output power. It is fitted with a 2A USB socket to charge a wide range of items such as a smartphone, MP3 player or a tablet while still keeping the mains socket available to power an additional item such as a battery charger. It can operate for four hours continuously and includes shutdown protection to power down the inverter if the battery power drops below a certain level.

Charge your laptop, printer or phone
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 12V 100W Modified Sinewave inverter 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 Simple and good value inverter. Use this inverter to run a 21" TV in my caravan when we have no access to mains electricity. Works perfectly and the cooling fan is quiet and unobtrusive. The compact size is particularly useful in the caravan where space is at a premium.

Rated 4 out of 5 by from Compact, seems good value and does what it is advertised to do. I bought this to power a small 60W mains TV from my boat's 12V system. It worked, with no interference to the TV sound or picture. After a while I was aware of a slight noise from a cooling fan - but nothing too obtrusive. I had been a bit concerned because I had already tried a slightly smaller inverter (which should have worked in theory) without success.

Hi, would this be suitable for ghd hair straighteners and a hair dryer in small Renault Clio?  I don't want to purchase it and have my battery go flat from using it and be stranded in a camp site Thanks in advance.

Asked by: bunts123
It would work well for the straighteners if they use less than 100w, but would not run a hair dryer due to the wattage.
