That's how I bought my Spectre, as a refurb for about 1k (~500 off) and it was the best choice I could've made, amazing laptop handles everything I throw at it between cad and Adobe stuff and it came with no blemishes and no visible issues. the refurb was perfect. I'd say go for it

I'd recommend this charger, works past the DRM and allows multiple plugs

I'm actually looking at purchasing this one. 60W USB C PD with type A ports.

I don't mean to be obvious, but if the laptop comes with a 65W charger then that it what it needs to charge at full speed. 30W is NOT enough. There are several chargers with 60 or 65W power delivery that come with a USB a charging port as well on Amazon. This one took me 2 minutes to find: https://www.amazon.com/Cable-Matters-Charger-Delivery-Smartphones/dp/B01MS9CTB7/ref=sr_1_6?ie=UTF8&qid=1525366852&sr=8-6&keywords=usb+c+charger+65w. I have no idea if it is any good.

I bought the following: https://www.amazon.com/gp/product/B01MS9CTB7/ref=oh_aui_detailpage_o05_s01?ie=UTF8&psc=1

It works great, rapid charges my phone and charges my computer quickly (but not as fast as the original charger).

Contains three extra USB2.0 ports so you just need to carry one other cable to charge other devices.
