So we went on a trip for a week and a half, so the BMW 320d (yes I should specify) didn't drive for that time. When I tried to start it yesterday it had a dead battery. Luckily not dead enough for all the electronics to loose their settings, but not starting dead.
So went and borrowed a friend's (thanks Paul) jump starter. It's one of those small Lithium battery jump starters and it worked as a charm.
This got me thinking I'll have to get one of those. Some googling taught me that
- there are a lot of those out there
- they come in all different sizes (roughly 5000mAh to 20000mAh)
- most of them have additional extras like flashlight / usb charging ports / compass / ....
One thing that's really missing from most of these is the ability to charge from USB, which really hampers the power bank function of the thing. I have a nice solar panel to charge it, but can't use it.
I'll keep you posted if I find one that's USB rechargeable (and doesn't cost 150$ like the noco geniusboost)
