Modified sine wave interter uses

laptop and battery chargers ok. Motor driven devices like fridges tend to want a full sine wave inverter.

Hi Ben

You can expect to run it on almost every electronic device you have including your laptop.

Of the many devices I have tested not one has failed however some are not quite as efficent like a microwave oven I had rattled a bit due to the square waves and did not put out quite as much power as expected.

Hi Ben

Yes it can be used on most products but also depends on the quality of the unit. I sell to tradesmen who charge cordless drill batteries and some of the cheap and nasty inverters burn out the chargers. If the charger gets very hot then the inverters modified wave is poor.

Below is the Projecta application chart.

Hi Ben, I bought one myself, to run the kids Playstation2 whilst travelling.
Found a couple of things out:
It won't run a playstation 2, they need true sine wave.
It won't run/charge my Apple powerbook laptop.
But it will power Playstation 1. (so its not totally useless).

You only mentioned small items that would rum from an inverter with a capacity of 300W or less. I take it you are intending to run small items.

It pays to tailor your inverter to the largest item you will be running. The efficiency of an inverter is calculated running at or near maximum output. The "inefficient percentage" component is the power that it takes to run the inverter circuitry - this power does not reduce much as you reduce the load. To put it another way - the bigger the inverter, the more power it takes to run it.

If you can get away with a 250W inverter you will only be wasting 25% of your precious battery power than you would waste by using that 1kW one. If you are only wishing to run small items you will be far better getting a smaller sine wave inverter.
