I got this Camel Energy multi-function jump starter to keep in the SUV primarily as an emergency jump-starter, but also for its tire inflation and its power bank functionality. You charge it through its USB-C input port. (A USB-A to USB-C cable is included but an AC adapter is not).Once charged you can use it as a jump-starter by connecting the jump-start cable to its dedicated outlet (that’s covered by a tethered silicone cover). The jump-start functionality is smart. It warns you if you’ve reversed the polarity, or if the temperature is too high, and it lets you know if it’s ready to go. When I first wrote this review, I warned that I didn't have a dead battery-car to test it. But I'm revising my review because, in a massive coincidence, my 1992 Acura Legend (3.2L V6) needed a jump start the day after I got this jump-starter. It was able to start my Acura on the 2nd try. For my 1st attempt I probably didn't wait long enough after connecting the jump-starter, and so it turned over briefly but didn't start. The 2nd try, I waited about 1 minute before turning the ignition key, and it started right up. Woo hoo! Now I know that I can rely on it! (But now I have to figure out why my battery died.)As tire inflator, it’s very intuitive and very fast. It’s slightly faster than my fastest Li-Ion tire inflator. (I have 4 for my 4 vehicles and I’ve given 3 to relatives for presents. I’ve timed all 7 for inflation speed.) Timed with a stopwatch for my SUV tires… When filling the tire from 32 psi to 34 psi, this Camel Energy inflator only took ~38 seconds (or 19-seconds per psi). That’s impressive.Unfortunately, the digital meter is off by 1 PSI. When I set it to 34 PSI, it inflated my tire to 35 PSI (according to my 2 trusted digital tire pressure gauges) before automatically shutting off. That’s disappointing, but I’ll tape a note to it saying to set the pressure 1 PSI lower than desired.The inflator can be set for different pressure measurement types, like PSI, Bar, Kpa, & kg/cm2.There are user-created pressure presets for 4 different targets (like car, motorcycle, & bike). You connect the hose to the inflator and the tire, you set your chosen pressure, and turn it on. It stops inflating when it reaches the set pressure.The unit comes with a clamp-on Shrader connector for Shrader valves (like those used on cars and most bikes). It also comes with a Shrader-to-Presta adapter for inflating Presta-valve tires. And it comes with nozzles for inflating toys, and a needle for inflating balls.The unit has a built-in flashlight and emergency-flasher light which work whether or not the tire is being pumped. That’s a great feature—especially for nighttime inflation, and extra especially for nighttime roadside inflation.The unit can be used as a 24,000 mAh power bank with a USB-A port and a USB-C port that can be used to charge devices like smartphones. It is not auto-sensing, so you have to turn it on in order to charge devices. It does not support fast-charging from its USB-A port, but it supports fast-charging (not super-fast charging) from its USB-C port.It comes in a nice case. It’s only about twice the size of Li-Ion tire inflator that doesn’t have jump-start capability. That’s great.The user manual is very well written, but the product is so intuitive that I didn’t need to read it before using it for inflation.The price ($99.99 at the time of this review) is reasonable for a jump-starter with this level of cold-cranking amps. I like the multi-use functionality, and ease-of-use of this Camel Energy jump starter, so I’m giving it 5-stars.
