Normally, domestic consumption of electricity in Nepal comes to 220 Volts/50 cycles. Climatic conditions in Nepal may bring in fluctuation in electric supply leading to load shedding. However, Nepal hotels have UPS (Uninterruptible Power Supply) to deal with this electric crisis. It is advisable to carry voltage converters and plug adapters with you while travelling in Nepal for using electric goods. Voltage converters and plug adapters are easily accessible at shopping malls in the cities of Nepal.
I traveled with you in Bhutan and Nepal. I have very warm memories. Thank you once again!
