Good deal, but sort by price on these things and they are $20-$25 all day long.

I almost bought it but then decided to buy this one instead

Its $.50 cheaper, and The Oxilam has a larger 12,800 mAh battery, a 4 warranty vs 2 year with this one, wider operating temperature range, USB-C input with two USB-A outputs, a brighter 600-lumen flashlight, and more built-in safety protections 10 vs 5.

Nice. Keep in mind a few things with these. I could have missed it but the usb-c doesn't specify output max, e.g. 18w, 30w, etc. That said, I wouldn't use these for charging devices. You don't want to need it only to find that it's drained because you charged stuff off of it. USB battery chargers are cheap enough these days to leave this dedicated for its purpose.

Second, I always try to look for boost mode on these. The safety protections check for polarity (positive is on positive, negative is on negative.) This is a good thing. However, if your battery is completely dead, it won't pass the safety checks and won't activate. Boost mode bypasses this check. You can trick a non-boost mode unit by attaching a volt meter to it, although tricky to do while trying to jump.

3rd, don't leave these in a hot car, the battery will swell and can explode if temps get extreme. For this reason I actually got a smaller one that I can keep in my backpack. Unless you have some 6+ liter diesel, most of the packs will work fine. If you don't want to carry it around, look for a super capacitor type jump pack. They are more expensive but safe to keep in extreme temps.

extreme heat is bad, what about extreme cold? I live in Chicago so weather is crazy here...

The risk of thermal runaway isn't there (explosion) but it could drain quickly or not offer enough power. That said it's operating range goes as low as -4 F
