Once again it happened. I was working at a remote office... and I mean REMOTE. I was the only one there, and no other businesses within walking distance. I was setting up a new branch office so I had my car pulled into the shop/warehouse to unload and work out of my trunk. Ive done this for 5 years without issue. Now in the last year or two, doing so apparently runs my battery down to the point the starter wont turn over. Ive already checked the battery repeatedly and its fine.
Luckily the last 2 times I lucked out. The first time the service manager lives literally 5 minutes away from that building, and was able to come over and give me a jump start. Today the closest colleague was 45 mins away, but I happened to find a battery charger on the shelf and I was able to hook it up for 15 minutes and top off the battery.
So I figure its time to keep a jump box in the trunk so I can take care of myself if it happens again. But I want to hook up the charging port to my electrical system so its topping off the box when the car is running. The last thing I need is to need it and find out it didnt hold a charge.
Anyone have a suggestion for a good portable jumpstart box that charges via a 12v adapter? Doesnt have to be particularly small because its going to sit in the trunk all the time.
I wish I had the room for an accessory battery with a switcher system. I saw one that would constantly trickle both batteries, but when the ignition was off the main battery was disconnected. So if you ran a battery down it was the one for the accessories, not the starter system.
