Electric shavers with USB-C port

USB-C

— the most versatile option for electric shavers: the same cable is used as for a smartphone, laptop, or power bank, with a reversible plug, and the current usually runs on a standard 5V from any USB adapter. This is convenient on the go: gaining a couple of percent from the laptop in 5–10 minutes is enough for one shave; at home, it can be connected to any power source. It's important to consider the water resistance of the specific model: for wet-dry shavers, the USB-C port is often covered with a cap, and the fast charging behavior depends on the shaver's electronics, not just the "power" of the adapter.
