Sometimes, the cable of your electrical appliance is too short to get into the back of the garden or to get to your work table. An extension cord offers the solution in that case. In the manual of your product, you can read exactly whether you can use an extension cord and which one is suitable. Do you want to use an extension cord outside? Look at how waterproof it is. For example, IP44 means that it is splash proof. Next, choose the length that suits your job, such as a 10-meter extension cord or a 20-meter one.
