Interesting to see that CPC advertise some of their 12V input, 230V
output inverters as a means to 'charge batteries ... in case of a power
blackout.'

Editorial licence? There's plenty of that around - see 'False

A *lot* of inverters intended for use with solar panels also have
battery chargers built in so they are a 'one box' solution to supply
power. Just add solar panels at one end and a big battery at the
other end and you have mains power all the time (assuming there's
enough bright days of course).

Not sure if the CPC ones are actually both inverters and chargers but
I can see how the description could easily get copied from one to
another to cause the error (if it is an error).

I think it is the case for computers and phone batteries and it can be
handy.

Somebody does not know their inputs from their outputs.

I think the advertising copy writers should be invited to place their
tongues on the output and input terminals so they can appreciate the
concept.

No they aren't. They are ordinary cheap as chips ones badged as Mercury.

but

It happens. One site I looked at had copied the blurb about true sine
inverters and inserted it as a continuation to the blurb about each and
every modified sine item.

It's a bit like price errors though isn't it, you never get true sine
inverters shown as modified sine, it's always the other way around!

I've been looking for a true sine inverter of around 1000 watts for
some time now and it's amazing how many there are out there incorrecly
described. Often the heading says 'true sine .....' but down in the
specification it says modified sine wave.

They could be used to charge some types of batteries in the case of a
power blackout.

12V battery Inverter 230V AC input charger for D/C/AA/AAA batteries.

Or more likely mobile phone. Which of course are used for far more than
just talking to the base station (which will also be off!)
