  • Description

What's the different between high frequency and low frequency?
High frequency power inverter have limit for running appliances with motors, engines, special light and TV
Low frequency power inverter available for sensitive load, accept generator’s energy output, high power factor, and follow our warning label, it would not have any problems.

Ideally suitable for Journeys, Camping, Tents, Boat Trip, Working on the way and everywhere, where is no electricity !
Simply connect our with a 12v Battery.
For example as in a Car, Motorcycle, Camper or Boat and use 220v-240v electrical appliances.

Why you should buy our Power Inverter ?
1. Our PCB Board is manufactured by machines, not by hand !This is extraordinary clean and it gives no cable tangle !
2. Our Material is First Hand Material! We do not use "Second Hand Material" like many other supplier !
3. Important Delivery Parts are manufactured in USA, Japan and Germany, not in China !
4. The Power Output is very constant.When using Strong Machines the IC Program recognizes this and provides at the beginning a Higher Power which adapted later !
5. If you use our Power Inverter for a long time, you can see the difference to similar products of other suppliers !

How much Power should have the Inverter?
If the label of your electrical appliance does not shows the Watt, but you know the Amp (A),
you can calculate the Watt with following formula:
Ampere (A) x Volt * (V) = Watt
(*230 Volt Europe, 240 Volt Australia, 110 Volt America)

All Television Sets, Monitors, Notebooks, Coolers, Pumps, Machine Tools and many further inductive devices have an extremely high short term starting current.


If your TV equipment indicated an output of 150 Watt, the starting current can be up to 10 times.This would mean, that you must select a Power Inverter, which can accept a short term maximum performance of 1500 Watt.
Please absolutely pay attention to this important factor and order none to weak Inverter for your equipment.
Because it could damage the inverter and your appliance ! If you want to use our Power Inverter with a special Appliance, please ask us first !
