   This Portable Car Jump Starter with Air Compressor is a must-have for any car owner. It’s super easy to use and works perfectly—I’ve used it to inflate/add air to my tires without any hassle. I have not had the need to use the jumper cables — and would not mind never having the situation where I have to…

   What I love most is how it holds its charge, so I know it’s ready whenever/if-ever I need it. It gives me real peace of mind knowing I’m prepared for emergencies, whether it’s a dead battery or low tire pressure.

   The digital display is clear and simple, and the built-in light is handy for nighttime use. Overall, it’s a reliable, all-in-one tool I’m glad to have in my trunk. Highly recommend!

   Worked in a pinch more than once. Helped a stranded driver once, had to jump my battery another time. I keep my tires full all the time without looking for a sit hose at service stations. Holds a charge abx charges back up easy and fast. Liked it so much I bought one for my son.

   First Impressions: Jolly good idea to have a tire-inflator and a jump-starter in the same device. Both run from a rechargeable battery, both equally probable in older vehicles like my 2006 Honda Civic sedan. Great packaging with minimal plastic and wastage. Bonus was the elegant case to carry it in the car – compact also. Comparable in size and weight with similar capacity batteries. See picture below.

   Unpacking: All contents were as described. It felt like the inflation hose was a bit short, later it did turn out to be a little hinderance.
   Initial Charging: Right out of the package, the battery was 88% charged. Fully charged it on a regular 5V, 2.4A USB charger and it got up to 99% in about an hour. See picture below. Charging times are in the range for most high capacity batteries.

   Charging Devices: Charged my iPad, 10thGen with a USB C charging port. It was about 54% charged and set it up to charge to max. It took about 86minutes, more time than charging it directly from the Apple 34W charger. Tried a few other devices including my Android 3500mah cell phone, not only did it charge the devices to full, it took about the same time as from other chargers.

   Second Charge: After a few charging experiments, the battery was down to 58%. This time put it on charge using the 60W laptop charger. It took about two hours (see picture) to charge to 99%.

   Tire Inflation – bicycle. Tried to inflate the bicycle tires, which were fully flat, with the inflator. Needed a convertor to connect the hose to the tire. Setting the pressure request was very easy and intuitive. It took about 2 minutes to inflate fully and automatically shut off when done. May not be an ideal inflator to take on the bike rides, but useful in preparation before the ride.

   Tire Inflation – Car. Not sure if I should risk deflating the tire to try out the inflator, I deflated the driver side front tire to below 30psi and set the pressure to 34, since the tires were hot. It took close to 135 seconds to come up to 34, observed that from 33psi to 34psi, it took close to one minute. May not be a great device to inflate the tires every time, but on an occasional roadside problem, it will be of great help.

   Opinions: A good gadget to have for emergencies, and a good value for price. I would recommend checking the charging more often to ensure that the battery is fully charged, especially before a long drive.

   I used 1 time to fill my tires at 36psi it’s worked very good, but it’s took little time to fill a low-low air tire. I didn’t use the jump start yet.
   It’s look good, very good size, nice carry case, easy for storage or carrying in the cars, very good built

   I have had the jump starter for about a month and it has already jumped my car multiple times and saved some strangers with car troubles as well. It also filled up all of my tires easily, one was nearly flat and I was have to fill it up to 30psi. It does need to be charged every other week or so, and leaving it in the car with drastic temperatures will drain it faster. I keep it inside and it holds up everytime I need it.

   It is a good product. Love that it is light weight and portable. Easy to use. Ranked it a 4 as it did not jump start my Tahoe. But all other vehicles, no issue. Air compressor is excellent!!
