These inverters are very popular not just because they are good value for money but are reliable and easy to use.
They come with a proper 13A 3-pin socket fitted and two leads, one with a cig lighter plug and the other with crocodile clips.
Built-in variable speed cooling fan.
This 12V version requires 30A on full load - so must be wired direct to the battery. You can get up to 150W from it if used from a cig lighter socket.
