  • Frequency: 60Hz
  • Plug Type: A, B, C

Vietnam 🇻🇳

  • Voltage: 220V / 380V
  • Frequency: 50Hz
  • Plug Type: A, C, F

Indonesia 🇮🇩

  • Voltage: 230V / 400V
  • Frequency: 50Hz
  • Plug Type: C, F, G

Malaysia 🇲🇾

  • Voltage: 240V / 415V
  • Frequency: 50Hz
  • Plug Type: G, M

Thailand 🇹🇭

  • Voltage: 230V / 400V
  • Frequency: 50Hz
