I didn’t want to spend the money, but once again the car wouldn’t start. It’s been over a week since I had driven anywhere, and again the battery was insufficiently charged. I needed to get some documents dropped off two miles away, but roadside assistance wasn’t going to arrive for an hour. Someone gave me a jump, but I need a better option. This was at Costco for $60 and besides jump starting the car serves as a power bank and Qi charger. I didn't expect the last feature but am happy it's there. I guess I can move my existing Qi pad upstairs and just keep this thing at my desk.
