A universal charger is a battery charger that can be used across multiple electronic devices. Specific universal chargers are typically meant to be used in conjunction with a one type of device such as laptops. However, when universal chargers are being discussed, conversational participants may be referring to cell phone chargers.

The Association has begun an initiative to standardize cell phone charging. As part of the initiative, the Micro-USB interface has been chosen to be the common universal charging interface. Many phones will be built around this charging model. As a result, most phones will be compatible with a universal cell phone charger in January 2012, though some will still be shipped with manufacturer-specific chargers.
