'kill switch' hmmmm never thought about it..hahahaha

then again, dont want to do any more mods to the car.. 

I'll get my car check concerning the parasitic loss and hopefully it will fix those battery drain issue.

if can settle the parasite loss then thats the best

if not everytime go jump start also problem

I got charger at home , not useful end up planing to get pb jumper as well.

I never thought that I would say this but why is your charger not useful ?

When yr battery internal issue etc charger won't be much help.

powerbank can last quite some time.. you can see this local review, he kept about month plus before officially use it



personal experience, I once kept the PB for 2 months before start using it again and somehow it still maintain the same charge and able to jumpstart my car.
