HP Chromebook USB-C charger wattage

HP’s own charging guide puts HP Chromebook / thin & light / tablet in the 45W class and names the HP 45W USB-C LC Power Adapter for models such as HP Chromebook 14, HP Chromebook x360 14, and HP Chromebook 11. HP’s accessory specs for part 1MZ01AA say it is compatible with HP Chromebook PCs with a USB-C® port (output 45 W; voltages 5V/12V/15V). Match the wattage on your lost cube, then shop a nearby 45W USB-C PD / GaN brick — or 65W when you want PD headroom (HP says a higher-watt USB-C PD charger is safe; the Chromebook draws what it needs). This Chrome OS page is distinct from Windows HP USB-C (Envy / EliteBook) and from Lenovo Chromebook USB-C / Acer Chromebook USB-C.

Official HP Tech Takes / buyers-guide wattage tables and HP accessory product specs for the 45W USB-C LC adapter publish these Chromebook classes and the 1MZ01AA part number (accessed 25 Sep 2026). Confirm the number printed on your brick or in your HP Chromebook setup guide before you replace it. Full method: how to pick.

• FAQ (HP Tech Takes) What charger do HP Chromebooks use? Published answer HP Chromebooks typically use USB-C charging with 45W chargers. This wattage is standard for models like HP Chromebook 14 and HP Chromebook x360. Shopping note Match the printed Chromebook wattage — do not downsize from a 45W Chromebook brick to a random 18–20W phone cube under load
• Higher-watt USB-C PD (HP Tech Takes) Using a higher-watt HP USB-C charger Published note HP USB-C chargers use Power Delivery and automatically adjust. A 65W charger can deliver 15W, 27W, 60W, or 65W based on the connected device. You can safely use a higher-watt USB-C charger; the device draws only what it needs. Example: a device requiring 45W can be charged with a 65W USB-C PD charger.
