“I was skeptical about this cable but after just 5 minutes of use I just can't live without it: if your setup requires you to often turn on/off your RPi4 this cable will turn in very handy.
On the other hand, if your Raspberry works in "always-on" mode you can rely on the official power adapter.”
“As usual, from this excellent company, the 'USB-C Cable with on/off Switch' arrived within two days of my order being placed (often the following day after placing the order). They were in excellent condition, well packed in a sensible package. The device, as usual, worked flawlessly.”
