I bought this for backpacking; I also can't be bothered to find outlets and PCWorld's review got 23 hours off this pack on a XPS 15

Dell Power Companion review: Charge your laptop on the go | PCWorld

it can also charge a host of iOS/Android devices @ 5V/2.1A with 2 regular USB ports

but please don't compare an avg Anker/RavPower etc which is too weak to power laptops; this is a meaty 19.5V/4.62A bank

this can be charged in-line (so you can charge your battery while you charge your laptop dawg)

I needed proprietary USB-C adapters so seeing if anyone can make use of this

If your Apple/Asus/Lenovo/HP/Surface/Acer/Razer/Alienware etc. uses either the traditional 4.5mm or 7.4mm barrel connector, you should be gravy.

asking $120
