Electricity in Nepal is typically supplied at 230 V and 50 Hz frequency. You won't need a voltage converter to operate your electric or electronic appliances in Nepal if the standard voltage in your nation is between 220 and 240 V, as it would be in the UK, Europe, Australia, and the majority of Asia and Africa. A voltage converter and a plug adaptor are required before utilizing your appliances if the standard voltage in your nation is between 100 and 127 V, as it is in the US, Canada, and the majority of South American nations. In the event that you intend to visit more than one nation, you can perhaps require a variety of plug adapters. In this situation, if you want to bring several electrical and electronic gadgets, it is advised that you purchase a universal adapter and a conversion kit.
If you are unsure about the voltage issue, you can look for a label on your equipment. If your appliance has a label that reads "INPUT: 100-240V, 50/60 Hz," it can be used anywhere in the world. In general, all computers accept universal voltages, as do some electric shavers. In order to prevent damaging it, you must examine your equipment and be certain of the voltage needed. You can think about getting a lightweight electric shaver if it is the only electric equipment you are bringing with you. Alternatively, you can get it in Kathmandu or other populated areas; but, not in isolated areas.
For all of your electronic and electrical appliances, it is usually essential to utilize an adapter with a reliable power surge protector because voltage fluctuations are fairly common in Nepal. As opposed to a few years ago, power disruptions are not as frequent today.
