Winter is here and I live in the UK and its getting cold.
I am tired of having to defrost my car, or sit in it whilst the engine runs to warm it up.
I was wondering if there was a way to carry a charged battery to the car, plug in a heater and leave it on in there 10-30 minutes before I leave for work in the morning.
I see lots of devices that will run off a 12v car socket, but I don’t want to drain my car battery, or leave my keys in the car whilst it is unattended. I need to find a Lithium ion battery that provides such a socket, that I can carry down to the car and plug it in. Either that or I need to find an all-in-one battery heater but I don’t think such things exist?
Anybody got any ideas?
