The Solytech S2000MKII Mini Slim Universal Notebook Power Adapter is arguably the lightest and slimmest 19V laptop adapters in the market. It is about the size of a cell phone, yet versatile and powerful enough to power your laptop and a 5V device like cell phone at the same time. It is designed to work with virtually any 19V notebook/netbooks, and it comes with 11 interchangeable/detachable tips. It is also designed to have protections against over-voltage, over-current and short circuit.
