center pin). If your laptop has the larger 7.4\u00d75.0mm barrel or only USB-C Power Delivery, this model is not suitable.<\/li>\n<li><strong>Match power:<\/strong> Your laptop\u2019s label or original charger should list 19.5V and \u224845W. Using a lower-wattage brick can cause slow charging or warnings. Using a higher-wattage HP Smart Adapter is usually okay but may be larger.<\/li>\n<li><strong>Cable care:<\/strong> Avoid sharp bends at the strain relief. If the plug feels loose, inspect the DC jack on the laptop as well.<\/li>\n<li><strong>Travel-ready:<\/strong> Works worldwide (100\u2013240V AC).
