Question Is this charger supposed to charge my laptop?

[zzzhhh]

I recently bought this charger from Amazon: https://www.amazon.com/dp/B0C6KVGS48?ref=ppx_yo2ov_dt_b_fed_asin_title. I had thought when I connect, it should charge my laptop. But it does not. I am not sure if this is because the item I received is damaged, or this item is not supposed to charge at all. My laptop is HP Elitebook 840 G3, and I connect USB type-C cable from a 2.1 A USB outlet.

The link you've provided is for an adapter, didn't you get a power brick with your laptop?

I have the power brick, but what I want is to charge without the brick, but simply with a USB cable, because I don't want to carry the heavy brick in my backpack. Is that possible?

I don't know why you expected a 5v charger to work, but that listing specifically says to use with a USB Type-C with Power Delivery power brick, which is 100w at 5A/20v or up to 240w at even higher voltages. As you'd expect, those are pretty big.

5v at 2.1A is 10.5w which could not be expected to charge a laptop, plus the adapter probably doesn't have a boost converter to convert 5v to 19v either.

your still going to need a power brick of some kind a usb 2.0 doesnt have enough voltage to charge anything like a laptop. as bfg 9000 stated you just cant plug in and go from 5v to 19v.


make and model of laptop ?
