This converter is perfect for most small electronics from USA to be used in 220 volt countries. The only sure way to know if your appliance is compatible with this converter is to check how powerful your appliance is. Every appliance and electronic item has a small Label on it filled with information about that item. Please look for this label on the back or underneath your item and read how many Watts or Amps it says that item uses. Please note that some items need a bigger "buffer zone" because they tend to spike in power. If your item needs 200 Watts, then this converter is NOT good for that item because the required wattage of your item is too close to the Maximum wattage of this converter.
We do not recommend using this converter past approximately 80% of its maximum capacity of 200. If you use this converter at its maximum capacity for a prolonged period, it will eventually burnout.
Please note transformers are to be used with caution in any case. Keep away from moisture areas and children. We assume no responsibility for misused transformers. We can always recommend a certain size and model for any appliance or electronic that you have. Please contact us if you have any questions.
