How do they harm the battery ?They convert 12v power to 220/240v
Hammer batteries

How do they harm the battery ?
Had been looking at one for phone chargers etc .
Small ones are fine but also use about 10 % more power than straight 12v -- did not say harm batts just hammer them ---see my edit

Can someone explain, in non technical language, what inverters are? Why use them and how do you use them? Any draw backs?

A box of tricks which is connected to your leisure batteries and when switched on converts the 12 volt output from them to 230/240 as if you were on domestic mains power. There are many sizes small and large, some of the smaller ones are portable and plug in to your vehicle cig lighter of 12 volt plug.
I prefer a permanent fixture connected via an isolator switch to my leisure batteries and I have a 1000 watt inverter which produces 83 amps, therefore I can run any 240 volt appliance provided it does not exceed 83 amps (although the inverter can go unto 2000 watts for a short surge) This is just about OK for our low power toaster but you could not use a hairdryer. items that produce heat are not usually compatible with inverters but my toaster works ok for a short period.The 1000 watt inverter is large enough to power our laptop and charge mobile phones. The output from the inverter is routed through the motorhome to a double socket into which we plug the desired item. We have a solar panel which puts some juice back into the batteries on sunny days and we find we can be 'off grid' as it were more or less permanently in the summer nor having to worry about power consumption.
An inverter can deplete batteries very quickly if left on so you need to make sure your batteries are in good condition and fully charged.
There are two types of inverter the standard one which we have and a 'pure sign' inverter which gives a steady and purer flow of power. Some sensitive laptops need the pure sign type but for us the ordinary one is fine.
As said there are many types and sizes, some may think my 1000 watt is overkill. However it only takes out of the batteries what it needs to power the item plugged in to it. I am sure others will tell you what setup they prefer.
IMPORTANT. The 230/240 output from an inverter, if handled incorrectly will kill you just as sure as your domestic mains at home. If you are not sure what you are doing, get a professional to install for you.
sorry, completely incorrect.
A 1000watt inverter will produce a little over 4 amps @230v......1000w ÷ 230v = 4.347amps...
but at peak output it will consume 83.33amps from your battery........1000w ÷ 12v (nominal) = 83.33amps
In realty it will be higher due to electrical losses in the conversion from dc to ac volts, lost as heat which is the reason for inveters having a cooling fan, and is usualy in the region of 10% so could be around 92amps

I don't understand leccy, so will it draw 83 amps, no matter how much or litttle it's using ?cheap leisure batteries dont like higher power inverters as they are designed for a steady lower current discharge. a 1000watt inverter will draw 83amps per hour,

cheap leisure batteries dont like higher power inverters as they are designed for a steady lower current discharge. a 1000watt inverter will draw 83amps per hour, so flattening a leisure battery of say 100amp/hour in a little over an hour. this will then take several hours to recharge
using 12v chargers will use far less current from the battery and then allow it to recharge quicker
