Good points about the temperature and corrosion—I've had similar experiences. I used to keep my jump pack in the trunk year-round until one summer day when it was pushing 100 degrees outside. Went to help a coworker jump her car after work, and the thing was completely dead. Lesson learned: now I keep mine tucked under the passenger seat or bring it inside if it's really hot out.
One thing I'd add is to double-check your jump starter's charge indicator regularly. Mine has a little LED gauge, and I've noticed sometimes it'll drop from fully charged to half without me even using it. Not sure if that's normal battery drain or just my particular model being quirky, but it's worth keeping an eye on.
Also, totally agree about having both cables and a jump pack handy. I once got stranded in a parking garage downtown late at night, and my jump pack decided that was the perfect moment to fail (typical luck, right?). Thankfully, someone else leaving late had cables, and we got my car started pretty quick. Ever since then, I always carry both—better safe than sorry.
And speaking of corrosion on clamps... another quick tip is to spray them lightly with WD-40 or some other rust inhibitor after cleaning. It helps prevent buildup from coming back too quickly. Learned that trick from my dad years ago, and it's saved me some hassle.
At the end of the day, like you said, a little maintenance every month or two beats getting stuck somewhere sketchy at night.

Yeah, I've noticed the same thing with mine. I thought maybe I just got a dud or something. It seems like those gauges aren't always super reliable—mine once showed full bars but still wouldn't crank when I really needed it. Ended up stuck at a gas station at 11 pm... not fun.
Speaking of jump packs, does anyone else notice theirs takes forever to recharge after use? Last winter, I helped someone jump their car in freezing weather, and afterward my pack took nearly two days plugged in before it was fully charged again. Not sure if that's normal or if mine's just getting old. I've had it for about three years now, so maybe it's time for an upgrade.
Also, good tip on the WD-40 for the clamps—I usually just scrub off the corrosion with a wire brush and call it a day, but I'll give that a shot next time. My dad used to swear by petroleum jelly on battery terminals; messy stuff but seemed to work pretty well.
On another note, does anyone have experience with lithium-ion jump packs versus traditional lead-acid ones? I've heard lithium-ion models are lighter and hold charges longer, but they're also pricier. Wondering if it's worth making the switch or if it's mostly marketing hype...
I've had similar luck with those gauges...mine's basically decorative at this point. Last time I trusted it, I ended up flagging down some random guy in a Target parking lot at night to borrow jumper cables—talk about awkward. I've been eyeing those lithium-ion packs too, but the price tag makes me hesitate. If they really hold a charge better and save me from another late-night embarrassment, maybe it's worth it.

I can definitely relate to that awkwardness. A few months ago, my battery died right after leaving work, and I had to ask a coworker I barely knew for help. Not exactly the best way to make a first impression. Since then, I've been researching those lithium-ion jump starters too, but like you mentioned, the cost is a bit steep for my budget. Still, considering how unreliable my car's gauge has been lately, I'm starting to think it might be a worthwhile investment. If it saves me from another uncomfortable situation—or worse, an expensive tow—it could pay for itself pretty quickly. I'm usually cautious about splurging on gadgets, but practicality might win out this time...
Been there myself—nothing like standing around awkwardly while someone you barely know rescues your car. Those lithium-ion jump starters do seem pricey at first glance, but honestly, after having mine for a year, it's saved me more than once. Plus, the peace of mind alone is worth it. If your gauge is already acting sketchy, might be time to bite the bullet...
