IBM 49G2196 AC Adapter 49G2192 20-10V 2.0-3.38A 100-240V ThinkPad Laptop

IBM 49G2196 AC Adapter 49G2192 20-10V 2.0-3.38A 100-240V ThinkPad Laptop

The IBM 49G2196 (FRU P/N) / 49G2192 (P/N) is an external brick-style AC adapter made for IBM ThinkPad laptop computers. It accepts universal AC input and steps it down to a variable DC output to power the laptop or charge its battery. The unit features an IEC C14 AC inlet on the brick, a proprietary 3-pin output connector, and an inline ferrite filter block on the output cable.

Applications

This adapter was designed for IBM ThinkPad laptops of the early-to-mid 1990s era — the generation when IBM's ThinkPad line was first establishing itself as a leading business laptop platform. The variable 20–10V output range and proprietary connector are characteristic of ThinkPad power adapters from that period, which used a dual-voltage output scheme to support both powering the system and charging the battery simultaneously. These units are still sought by collectors and organizations maintaining legacy IBM ThinkPad hardware, as well as IBM field-service and parts suppliers. The universal 100–240V AC input means the adapter can be used on both North American and international power standards without a separate converter.
