Historical background of voltage standards
● Differences in origin:
◇110V: Promoted by Edison and Tesla, it became the early standard in the United States and Japan. It is still used today because it is difficult to upgrade after the popularization of electrical appliances.
◇220V: Promoted in Europe to reduce transmission losses, and later inherited by the Soviet Union, China, etc., becoming the global mainstream standard.
● Technical comparison:
◇220V advantages: lower transmission losses (half the current at the same power), lower wire costs (thinner wires can be selected).
◇Safety: Both 110V and 220V are far higher than the safe voltage (36V), and the risk of electric shock mainly depends on insulation measures and leakage protection.
Usage suggestions
● Voltage compatibility:
◇ If the appliance is marked with “100-240V, 50/60Hz”, it can be used worldwide (such as mobile phones and laptops).
◇ Single-voltage appliances (such as rice cookers) need to be used with a transformer.
● Plug adaptation:
◇ Europe commonly uses C/F type (double round pins or with grounding slot), the UK uses G type (three-pin rectangular), and Australia uses I type (triangular flat).
● Fluctuation range:
◇ 220V allows ±10% fluctuation (actual 198-242V), and the actual voltage in some countries such as India is 240V.
Exceptions and special regions
● Dual voltage countries:
◇ Brazil (110V/220V), Mexico (7V/220V), Taiwan (110V/220V).
◇ Differences in industrial electricity use:
◇ Japanese households use 100V, but industrial equipment supports 200V; American households use 0V, and industrial equipment is compatible with 220V.
Other considerations
● Voltage fluctuation range:
◇ The actual voltage in 220V countries usually allows ±10% fluctuation (such as 198-242V).
● Plug type differences:
You need to choose a conversion plug according to your destination, for example:
◇ Europe: Type C (double round pins), Type F (with grounding slot).
◇ UK: Type G (three-pin rectangular).
◇ Australia: Type I (triangular flat).
● Appliance compatibility:
◇ If an appliance is marked “100-240V, 50/60Hz”, it can be used worldwide (such as mobile phones and laptops).
◇ Single-voltage appliances (such as rice cookers) must be used with a transformer.
