USB-C headache (lemmy.world)

I have several usb-c devices:

My Samsung Galaxy phone

My camera battery charger

My rechargeable head torch

My portable battery/device charger

I would like: One cable to rule them all, one cable to find them, One cable to bring them all, and in the darkness bind them; In the Land of my travel shit where the shadows lie.

What wattage, version, output, recommendations can you give me.

Currently I have 5 cables, but I should really only need one.

Thanks in advance

As far as charging goes there are only 3 USB-C cables.

60W - All USB-C to USB-C cables can do at least 60W in the form of 20V 3A
100W (Deprecated) - USB PD 3.0 introduced up to 100W charging using 20V 5A. Cables need an EPR (Extended power range) marker in order to allow this
240W - USB PD 3.1 extended the limit to 240W via 48V 5A. These cables have a 240W EPR marker.

All USB-C devices are supposed to support one of these three modes. HOWEVER, some cheaper devices don't actually support the USB PD protocol, and only support legacy USB charging. For these you need a USB-A to USB-C cable or adapter. USB-C ports won't provide power unless both devices are able to negotiate
