really impressed with this battery jump starter box thing though, about the size of a box of kleenex, 56Wh battery, dedicated 12v input and output, and has a usb-c input for charging using a regular laptop style usb-c charger. Not sure I'm a fan of using USB-C for such high wattage but eh the industry has decided it doesn't care about that apparently. I wonder if the USB-C is an output as well, be cool if it could charge a laptop while out on the road and then recharge it using 12V when driving. Not having to deal with dorky jumper leads is really nice though, units self contained with its own bulldog clips on short pigtails.
