SINGAPORE — The USB charging ports on public buses here are of significantly lower voltage, which greatly reduces the likelihood of electrocution, the Land Transport Authority (LTA) said. «These ports operate at a significantly lower voltage of about 5V DC (direct current), compared to the 230V AC (alternating current) voltage of standard three-pin sockets,» it said in response to queries. LTA added that it regularly checks on public bus operators to make sure that their monthly inspections on their vehicles are up to maintenance standards. Some 870 public buses here are equipped with USB charging ports, the authority said. As at May 2022, Singapore has about 5,800 public buses. Malaysia has banned the use of three-pin sockets and USB ports on express buses since Nov 6, after an 18-year-old died from electrocution on Nov 1. He was using an electric socket to charge his phone while he was on an express bus to Kuala Lumpur. Malaysian Transport Minister Anthony Loke said on Nov 20 that the teenager died due to faulty electrical wiring installed by unlicensed parties.
