The Dell TK3DM is a 90 W mains adapter for laptops that use its stated output and connector. It converts AC input to DC power, delivering 19.5 V at up to 4.62 A. This makes the output specifications easy to check against the laptop’s power requirements.

It accepts AC input from 100 to 240 V. The laptop-side connector is a 7.4 × 5.0 mm plug with a centre pin, identifying this adapter variant. The black housing has a C6 inlet for the AC lead.

The adapter is supplied without a power cable. Its body measures 128.5 mm deep, 51 mm wide and 32 mm high, and the output plug is 12.5 mm long. These dimensions help check the available space and connector fit.

The 90 W output and centre-pin plug make the TK3DM suitable for a laptop designed for those specifications. Its 100–240 V input range supports connection to an AC supply within those limits.
