Based in the United States, Stanley Fatmax is a well known manufacturer that produces a wide variety of tools. Some of the tools they make are Automotive tools, and this is where we find the Stanley Fatmax J7CS. The Stanley J7CS jump starter is a mid-range option that\u2019s got 700 peak amps, and 350 instant amps to use when not so much power is needed. It also comes fitted with a 120 PSI air compressor that adds to its value, and at 10.6 pounds, it's light enough to be moved around without too much hassle. The battery charger exists as the middle-of-the-line choice between two other choices from Stanley, making it an ideal pick for buyers that don\u2019t want to spend too much money and still get a good amount of value. Go ahead and read through this review to see if it\u2019s the best jump starter for you.\r\n\r\nWhy We Like It - STANLEY FATMAX J7CS\r\nThe Stanley Fatmax J7CS is a two-in one jump starter that can take care of your car battery as well as your tires, making it great for users who don\u2019t want to have too many tools at the back of their trunk. It comes with a tire inflator so that you always have your tires in check, and a reverse polarity alarm in case you get the terminals switched up.\r\n\r\nPerformance\r\nThe J7CS jump starter offers a convenient choice for drivers who wouldn\u2019t want to buy a battery charger and an air compressor as two separate items. The J7CS will allow you to jump start your car battery whenever it starts to act up, and also doubles as a tire inflator so that your tires never run flat - something you\u2019ll not get with the Clore Automotive Jump-N-Carry JNC660. If you have a couple of gadgets that have run out of power, the 3 USB ports that the Fatmax J7CS jump starter comes with should be able to act as a portable power source to reboot your accessories.\r\nDesign\r\nCompared to the NOCO Boost Plus GB40 Jump Starter, the J7CS takes on a very ergonomic design with its front featuring the jump starter, and on it's back side, an air compressor. The handle makes carrying it around a breeze, and the 120-degree pivoting LED light helps get you a clear view of whatever you\u2019re doing at night. On the jump starter\u2019s dashboard you\u2019ll find its 3 USB ports, LED battery level indicators, a reverse polarity indicator, and the jump-starter power switch. Turn the jump starter around and you\u2019ll see the 12 Volt DC charging port, the air compressor switch & nozzle, and the illuminated pressure gauge.\r\nValue\r\nThe biggest advantages of this 700 amp jump starter are of course the multi USB port selection that it comes with, as well as the air compressor that you can use to inflate your tires. In case you get the terminals mixed up when clamping, the J7CS will sound a reverse polarity alarm to alert you, but it doesn\u2019t have a voltmeter which is present on the BEATIT G18 Jump Starter. The on-board power switch helps make sure that the clamps are powered only when you\u2019re ready, and immediately after use, the manufacturer advises that users should charge it for 24 hours for it to get back to peak battery capacity.\r\nSTANLEY FATMAX J7CS Wrap Up\r\nThe Stanley Fatmax J7CS is an ideal jump starter that\u2019s got a lot of customer reviews on Amazon.
