   The Buture portable Jump Starter Battery has proven to be an invaluable addition to my car emergency kit. The advertised 4000A boost is no exaggeration; it brought my completely dead 12V battery back to life in mere seconds, saving me from the hassle of waiting for roadside assistance. This feature alone makes it a worthwhile investment for any car owner. However, its utility extends far beyond jump-starting. The integrated 150 PSI air inflator is a fantastic feature and the included assortment of nozzles makes it versatile for various applications. Furthermore, the inclusion of a 4-mode LED flashlight is surprisingly practical. The bright steady beam is great for nighttime roadside repairs, while the SOS and strobe modes offer added safety in emergency situations. Its portability is also a significant advantage. The compact design and included carrying case make it easy to store in my trunk without taking up excessive space. Overall it is a well-built, versatile, and reliable device that offers peace of mind and practical solutions for a range of vehicle and everyday needs. It’s a smart investment for anyone seeking preparedness and convenience.

   Summary: Great battery capacity, quick charging via standard USB cable, fast tire inflation (see video) in a convenient portable format with settable pressure and auto shut-off, detachable charging\boosting cables, car battery boosting even if battery is dead, all in a neat compact zip case.

   An all-in one solution to the common woes of car ownership with the ability to boost a dead battery and inflate a flat tire in a lightweight portable package. In addition, the light is effective and has SOS and strobe functions for emergency situations.

   Gives me piece of mind knowing that I can revive my vehicle without outside help in case of emergency.

   I am very impressed with this little unit! I’ve had a portable jump starter for a few years, and I know they are great if you (or someone else) needs a jump start. Much quicker and easier than dealing with jumper cables, especially if the dead vehicle is in difficult spot to position another car to hook up the cables.
   The air compressor is a nice addition, and I’m happy to have it in my trunk “just in case”.
   I tested it out briefly, not too loud, and it was able to add approximately 1 PSI of air approximately every 20 seconds, and 1 PSI drained the battery by about 1%. Not too bad for a compact, relatively inexpensive unit. Very satisfied with this purchase!

   I’m absolutely impressed with this jump starter! The 4000A cranking power easily restarted my car, even in freezing temperatures. The smart inflator is a game changer—quick, efficient, and with a handy LCD display. It’s also packed with safety features, giving me peace of mind every time I use it. The design is compact and portable, yet offers so many functions like charging devices and providing bright emergency lighting. Highly recommend it for anyone looking for a reliable, all-in-one tool for their car!

   Absolutely impressed with this Portable Car Jump Starter with Air Compressor! This is one of those products you hope you never need — but when you do, you’ll be so glad you have it. I bought this mainly for peace of mind during road trips and winter weather, and it has already proven to be a fantastic investment. The jump starter is powerful — it easily started my SUV with a dead battery in seconds. With 4000A peak current, it handled both my gas and diesel vehicles without breaking a sweat. The built-in air compressor is another game-changer. It’s fast, accurate, and perfect for topping off tires or even inflating sports equipment. I really appreciate the clear display screen — it shows battery level, pressure readings, and makes the whole process very user-friendly. Plus, the emergency light is bright enough for nighttime situations or signaling for help. Compact, well-built, and easy to store in the trunk — this device gives me total peace of mind on the road. Highly recommended for anyone who wants to be prepared for roadside emergencies!

   This is my second time buying this product, and I like it so much that this time it’s a gift for a friend. It’s a fantastic “Swiss knife” to have in your car – it can jump-start my medium-sized SUV and inflate the tires as well. I’ve tested both functions, and they work flawlessly. Moreover, it acts as a dependable charger for phones and smaller electronic devices (just steer clear of using it for laptops, as the charging speed is too slow). There’s also a flashlight that can double as a strobe light (I haven’t used it yet, but I’ve checked it, and it’s quite bright). The LED display is clear and provides useful information. Lastly, it features a USB-C charging port (though the charging speed is around 10W, so don’t expect it to charge quickly). Everything needed for these functions is included, along with a charging cable. One nice feature is that the air compressor ends get hot after inflating the tires, so it’s great that there’s a sheath to cover them, making it easier to handle the inflating cable after use (the time it takes to inflate the tires is a bit longer than at a gas station, but remember, you can do this at home without waiting in line, and it won’t cost you anything!). All of this comes in an attractive, zipped, semi-hard-shell case. My only small complaint is that the icons on the device aren’t quite self-explanatory, so it’s essential to keep the manual, which is quite detailed – so don’t discard it!
