Powers inverters generate a direct current DC battery power into alternating current AC the normal power frequency that runs all your normal electrical equipment in your home.The DC power flows in one direction only, whereas the AC power can switch from negative to positive many times a second.
Why would you need a power inverter?If you are intending to travel around the countryside, either in an RV/Caravan or even in a tent there will be times when your phone has gone flat or the torch batteries have suddenly died on you. This is why you need an inverter. You will save money and time running back and forth to the shop looking to buy new batteries.
These are great to use in the car when your kids watch DVD's on their little electronic gadgets, or any other electronic equipment that needs recharging from time to time when not at home.
Always carry your electronic or necessary chargers for anything that will require recharging with you when you go on holiday. Now, if you have the chargers for all your electronic objects or flat batteries you can recharge them by plugging the chargers into the inverter, turn on the power and presto, in time your equipment will all be recharged and back to original working capacity.
