For HP (Hewlett-Packard) laptops. (※Please double-check the size of your AC adapter, even if it's an HP product, before ordering.) This adapter allows you to charge HP laptops that do not support the latest Type-C charging (PD charging). I find it very useful because I can share a PD charger with my smartphone when traveling for business. (Photo 4 shows it actually charging.) Supports up to 100W and has a metal casing for sufficient heat dissipation. ※Please use a USB cable that supports PD charging. (They are also sold at 100-yen shops recently.)
