12V Portable Car Battery Jump Starter $99.99

You still need a charger to fulling charge your battery. Charging your battery with your car alternator will never fully charge your battery.
Just my $0.02

But the jump starter is useful for emergencies. I was stuck with a car that didn't start on a hot summer day with a screaming newborn, and I was lucky to have a kind stranger help me jump start the car. I bought one of these the same night.

But you're right; SLA batteries don't like to be at lower than optimal voltage. If you're not driving the car for a while (say 1-2+ weeks), disconnect the negative. If the car hesitates to start; trickle charge using a charger until it's healthy again and monitor voltage.

I bought it originally thinking it would be a great backup for friends/family during the 'vid not driving.

That being said, it has helped

1) jump a friend's car when he didn't drive to work a lot
2) my own car TWICE, when the brand new SLA battery failed

+has USB-PD (Type-C) in/out so no proprietary barrel connector for charging, I could take this inside and plug it anywhere, granted it might take a while without PD.
+flashlight
+comes with power brick + USB cables
+is essentially a large format powerbank (emergency usage?)

The only gripe I have with it is the "boost" button, when the jumper can't sense line voltage it needs a small pen/stylus to press the boost button. I use my pinky nail and just manage to get it pushed enough to click.

Too bad it was pulled from Amazon.ca for fake reviews. It's been nothing but solid to me, and I got it at ~$115 IIRC. I agree a good battery charger will be a better investment. But most people just aren't going to go through that for a ~$100 SLA battery and by law of large number, won't. This is something you keep in the car, and I'm glad I do. The caveat to that is if you don't live in Vancouver and it gets to -39532905378 degrees it could slash it's effectiveness.

Oh and before someone calls it out, OPs account is 4 days old... has a shilly wiff. But I still like the product.
