I bought this NOCO Boost Sport GB20 500A 12V Portable Lithium Jump Starter - Black B+ as a just in case
After reading about a few ZS EV Gen1 members getting caught out with low SOC in their 12 volt batteries, when they where using their radio etc, with the car was in “STANDBY” mode and not “READY” mode.
So, two years ago I decided it would be a good idea / back up plan, to purchase a 12 volt jumper / booster pack.
It lives under the drivers seat, just in case of a low SOC in the battery.
It has now been transferred over to our ZS EV LR.
Strangely enough, in the last three years it has been used more than enough times to boost OTHER people’s cars !.
It’s one of them really, you buy one and it sit’s unused for months and months on end, but then one day completely out of the blue, with out warning, it’s services are suddenly called upon !.
Then the cost outlay is 100% worth it.
It’s about as close as you can get, to carrying a spare 12 volt battery around with you !.
