12 Volt DC To 110 Volt AC

400 watt modified sine wave.


Is this good enough for charging batteries etc?

Here is an example.

Yes, that is more than enough.

You can calculate the power required with Ohm's law. P = I V (Power = Current x Voltage)
Using my laptop as an example, it takes 19V at 4.74A so would theoretically need 90W of power. It's less because it's not going to be 100% efficient and that assumes everything in it is running full power. NiMH battery chargers are going to require considerably less.
