I swear every time there’s a thread from a Canadian OP asking for product recommendations, someone suggests Harbor Freight, which unfortunately we don’t have up here. Seems to happen to me every time.
A few years ago during winter I bought a Noco Genius trickle charger for my Dad and the wires split at the stress relief the first time I used it. I ended up exchanging it for a more expensive model, but not surprisingly it had the same garbage insulation that became completely stiff and brittle when temps got even just a little cold. Ended up proactively taping around the stress relief and some other areas to prevent cracking and it’s been okay as far as I know, but that’s only because he’s careful not to bend the wires when plugging or unplugging.
Unless the Noco model you posted has better insulation on its wiring, I would look at something else.
