BESTEK 300W Power Inverter DC 12V to 230V AC Converter with AC Outlet and 4.8A Dual USB Car Charger

Product Information

This time of year the leisure battery thinks its fully charged by 11am so you can fill your boots with stuff charging or running of 12v early on in the day and its soon tops it back up again. Similarly, if you are driving from meeting to meeting you can plug the thing in and get it charging. Provides sine wave output which is more stable and can be applied to the curling iron, hair straightener and the electric toothbrush within 300W designed for your devices. Never really used invertors before believing them to be an inefficient use of power apart from an old one Don Madge gave me which was useful for charging old phones etc but I bought this one as Mrs D has a new laptop which I couldnt get a 12v adaptor for and also she knackered her electric tooth brush on the old invertor so as this one is pure sinewave it should have been safe for charging laptops, or other sensitive electrical items like tooth brushes, mobile phones etc. To determine an item's service and warranty coverage in your country, please contact the manufacturer.

The conventional modified sine wave inverter is generated by the stepwise superposition of the wave voltage of square sine wave. In recent years, with the rapid development of power electronics technology, PWM pulse width modulation has been widely used to generate correction wave output.

You really want to put the socket in a hole of a box to protect the connections, though, to avoid a short, as you just brought your battery terminals to within an inch of each other. The sine wave inverter has well placed thermal protection sensors,The aluminum alloy casing with a few ripples,Unique vents and also a built-in FAN which comes ON under NO any loads or when the Inverter becomes Hot Once Powerred.

And if you had a big inverter supplying a smallish load, the inefficiency is greater as there is a minimum amount of overhead - so if you had say a 2000W inverter for arguments sake and you turned it on to provide a low wattage, it would be more wasteful than using a 300W inverter for the same purpose.
