FAQ’S & News

  • What size of generator do I require?

    All electrical products have a data plate with information regarding their power usage. For most power tools (drills, sanders etc), their listed wattage is all the power they require to run. Household items such as central heating pumps, lights, TV’s, video recorders etc. fall in the same category. Items such as freezers, fridges, washing machines, some lawn mowers are normally different, whilst they can state a wattage rating, due to the type of motor they use can require a much greater requirement on start up, when started they then require a smaller usage.

    If you are unsure as to what power usage a product has it is always advisable to contact the relevant manufacturers sales or technical dept, quoting model number and requesting the START UP wattage & RUNNING wattage of your item. With this information you will be able to determine accurately the size of generator you require.

  • What is AVR?

    AVR basically gives the same output as an inverter machine. This feature limits the variation of the voltage of your generator to + or – 2 %. With a generator equipped with AVR you can run sensitive equipment such as computers.

  • Could I just throw away my old recyclable batteries?

    No, it adivisable that they be recycled. This includes Nickel Cadmium (Ni-Cd), Nickel Metal Hydride (Ni-MH), Lithium Ion (Li-ion) and small sealed Lead (Pb) batteries. You can look for a battery recycling seal on the rechargeable batteries found in cordless power tools, cellular and cordless telephones, laptop computers and camcorders.

  • What is the advantage of a halogen bulb?

    It provides brighter, cleaner light. However, it consumes lots of electricity and gets very hot. You should ensure that it stays away from draperies, bedding, clothing and hanging plants.
