I recently purchased this charger from Amazon. I expected it to charge my laptop when connected, but it doesn’t work. I’m unsure if the product is damaged or if it’s not designed to charge at all. My device is an HP Elitebook 840 G3, and I’m using a USB type-C cable from a 2.1 A outlet.

The connection you mentioned is for an adapter, not a power brick. Did you receive a power brick along with your laptop?

I possess the power brick, but I aim to charge using just a USB cable instead of carrying it. Is this feasible?

I don't understand why a 5v charger was assumed to work, but the instructions clearly recommend using it with a USB Type-C power brick that supports Power Delivery, which can deliver up to 100w at 5A or 20v, or more than 240w for higher voltages. It makes sense that these specifications are quite high.
5v delivering 2.1A equals about 10.5w, which seems too low for charging a laptop, and it's unlikely the adapter can boost the voltage from 5v to 19v either.

you will still require a power adapter of some type, since a usb 2.0 provides insufficient voltage for charging devices like a laptop. as bfg 9000 mentioned, you cannot simply connect it and expect a voltage jump from 5v to 19v. what is the make and model of your laptop?
