Because I live in Canada, for eight months of the year, it’s near-essential to plug in your car (for the block heater). But, as most people don’t know, you only need the block heater running for a couple of hours — yet most people will plug in the car when they get home from work, and leave it plugged in all night long.
That’s a waste. When I was a kid, my parents bought timers for their cars, so that they would automatically turn on at about 5 a.m., and warm up the engine block before the car needed to be started.
Now, I kind of have a similar problem. Instead of plugging in my car (for some reason, my car starts like a charm, even in -40 weather, and has never been plugged in) I plug in my cell phone, overnight, every night, so that it starts the day with a full charge.
Of course, it probably only needs to charge for a couple of hours — not eight to 10. And yet, I don’t have a timer or anything. What I need, instead, is this:
When the device is charged, the plug pops out of its own accord.
Good idea! So far, it’s just a design concept. But there should be no reason why the idea can’t be easily manufactured.
