Do you really need an inverter power generator?

I would like to buy a generator, as an older Honda EM500 unit in view.

Weis maybe someone of you like "clean" is the current (sine wave) of this aggregate? It's supposed to be a plant, power or a trimmer or n small TV with it. Just charge the phone or notebook.

It is possible to choose between 50 and 50 Hz on the unit.

or is necessarily an expensive inverter device needed.

Grade of the system and the tv could be problems…

The gardening tools are absolutely no matter and various chargers have indeed built in voltage converters, capacitors IDE and in addition, the device has a battery to buffers because it does not matter.

Inverter Aggregate Grade from Honda are considered the best of the best according to the pricing in the 4 Stellingen area.

I would actually take the genset in your place and if it does not work so well, a Honda genset will always provide some countervalue and it should be sold well right again.

Here are some information about such generators

On a conventional unit actually run ALL devices.
Devices such as TV's hi-fi and radios can play noise on a conventional aggregate (buzzing, humming)
On a conventional aggregate even supposedly very sensitive devices such as Laptos run problem-free, since laptop power supplies have a switching power supply.

An inverter unit makes a "better" sine wave, which is often superimposed by noise. Which is why here also devices such as TV hifi and radios noise (ringing, buzzing) can play.

Tip: If you operate a device with low power consumption on a conventional unit, voltage fluctuations can occur due to low speed. If you plug in a larger pantograph now (construction floodlight 500 watts), the power generator turns higher and produces absolutely unsteady power for television:-)

Incidentally, the "luminous flux switch" is a switch from 230V to 12V to the car battery charge.

To charge the phone is a generator not suitable, the ratio of energy use (fuel) and the low useful energy is bad. Better charge the phone from a DC power source (battery). An Inverter Generator can run at low speed when low power / power is needed. A normal generator must always keep at full speed around the 50Hz. For your applications you should use a battery with an inverter, which also makes less noise.
