The DTK DL-90W AC Power Supply Adapter Charger in black is a universal power supply unit designed for notebooks and laptops. With a voltage of 19V and an output current of 4.74A, this adapter is compatible with various brands and models of laptops. Manufactured by DTK in China, this unit is a reliable and efficient solution for powering your laptop while on the go. The sleek black design adds a touch of style to your tech accessories. I acquired a number of these in a liquidation auction, not tested as I don’t have laptops to do so but they look to be in new condition and my assumption is they they are good but selling as used.
