Power supply on/off switch

Sat Sep 14, 2019 5:57 am

Hi, I have a RPi3b+ and a new RPi4b. I have the following problem on both but mainly the 4b. The problem/issue is the lightening bolt voltage warming appearing a lot on the 4b, sometimes on the 3b.

I've read this is caused by non-official power supplies. I have bought 2 non-officials because they have an on/off switch but the cable is of course cheap and I assume that is causing this issue. I like to turn my Raspberries off after use as I didn't want to damage the input socket by over removal and insertion.

My question: before I splash out on 2 official supplies, why don't they have an on/off switch?

Cheers.

Hello
You can simply buy a plug-in strip with a switch on/ switch off. :idea:

The reason no on / off switch is included is because if a clean shutdown is not undertaken it can and does corrupt the Operating System.
