The new chargers will use a micro-USB plug, similar to that used for digital cameras, to enter the mobile phone for charging, Sarah Parkes, spokeswoman for the International Telecommunication Union (ITU), said on Friday.
Some manufacturers may also allow the cable to be disconnected from the adapter at the plug-in end and inserted into a computer through a USB port instead. The power from the computer, however, would be smaller than from a wall socket and would take longer to charge a phone.
Some manufacturers are already using the new system, said Parkes. A number of companies have signed on to the new deal either with the ITU or earlier with the European Union.
Manufacturers won't legally be required to use the new standard, but in practice holdouts from ITU standards are rare, she said.
"Every China mobile phone user will benefit from the new Universal Charging Solution," said the ITU, adding that the same charger could be used for all future handsets, regardless of make and model.
Parkes said it is likely to lead to a dramatic cut in the number of chargers produced, shipped and later discarded with each purchase of a new phone.
The new chargers will also reduce the energy consumed while charging, the ITU said.
It added that the new technology could lead to a 50 per cent reduction in standby energy consumption and a cut of 13.6 million tonnes of greenhouse gas emissions each year.
