How to choose a transformer?

It is necessary to choose a transformer with a power greater than 20% or more of the appliance. If the appliance is 900W, the minimum power of the selected transformer is 900x (1+20%)=1080W>1000W, so it is recommended to choose a 2000W transformer.

If the appliance is equipped with a motor, how to choose a transformer instead?

Appliances with motors such as air conditioners, refrigerators, and wall breaking machines should reserve 30% or more of the kilometers for transformers.

Is there anything to pay attention to when using it?

Power on for 15 minutes without any abnormalities before connecting the appliance for the first use. When using a 1000W transformer, the min. current of the main switch at home should exceed 20A, and using 2000W, the min. current should exceed 32A.

I do not recommend

Completely stopped working less than 3 months of use and talking to the seller there was no chance of replacing or fixing. Seller offered some support and I believe around £10 refund but, you can understand how frustrating it is, especially when this item was used less than 5 times in those months. Extremely disappointed, especially after spending £74 on this.
