Ease of use
Great drill and the battery lasts a very long time. Glad I got a second battery. It is charging and ready whenever I will need to switch them out.

Longer run time than my previous battery drill
After buying the skil starter set (drill, circular saw, flashlight, reciprocating saw) I purchased a second battery. It was a reasonable price came in five days and worked well that weekend when I used it

Supports all USB PD 3.0 voltages (5,9,12,15,20)
The USB C battery does what it says it does. I hope these USB C batteries take off, it's great being able to charge with a USB C car charger. I'll mainly be charging with the Anker Gan Prime 100W. I'm hoping they expand this line with 4 and 6 amp hour. I will be using this for my multimeter, soldering iron, and my skil products.The cable they ship with it should be discarded immediately though, it's about 1/3 the thickness of all my 100W rated USB C cables. Cable matters sells USB IF certified cables. I never use provided cables from any product though so this was a non issue for me.This was the only power tool battery I could find that charges with USB power delivery and they did an incredible job. I'm just starting to buy power tools and everything will be SKIL from now on due to this battery.

Price doubled
I paid 45 a piece for the 20v 2a usb c 100w batteries. They are nice but not for the 80 now that's double price. Don't pay that.
