   I bought this jump starter for emergencies, but when I finally needed it, it wouldn’t work. It was fully charged, yet it struggled to turn over my car and eventually did nothing. The flashlight works, but that’s not why I bought it. If you need a reliable jump starter, look elsewhere because this one let me down when it mattered most.

   Works great and very handy. Worked to jump my mower and worked great to help a motorist with a dead battery. The built in flashlight is very handy when trying to hook up the cables at dark.

   Portable Car Battery Jumper Starter 4000A Peak 12V Battery Pack with LCD Display and 3 Modes Flashlight Roadside Emergency Car Kit Up to 8.0L Gas & 6.0L Diesel Engines

   These cane be a lifesaver. keep one of these in my truck. As another reviewer said the cables are a little short. Which could make it challenging to find a safe place to put the battery when connected to the vehicle depending on whats next to your battery.

   Very powerful and very competitively priced. I tried a cheaper version one of these before and was disappointed. Well this one still is a lot less than some of the competition, it excels with its jump starting power. So far I’ve used it on an SUV, and multiple outboard motors. Several of the outboards I cranked were four stroke one with a 200 horsepower in the battery was nearly completely dead. It has some weight to it so you definitely know it’s got the juice packed inside. The cheaper one I tried before this one Weighed about a quarter of what this one does and claimed the same capacity. I didn’t care much for what it came with for a case so I got a separate hard case for it to store it in. But with the price you still can’t really beat it even if you have to spend 15 bucks on a better case.

   This portable car battery jumper is indispensable for any motorist who may occasionally leave the headlights on, or who may live in a hot or cold climate that challenges a car battery. That covers basically everyone. This jumper claims a substantial 4000A peak rating. Though I have no way to measure that, it does work as expected. As with all the others I’ve seen, the jumping cables are really short, which limits where you can place the negative clamp. (For safety, it should not be attached to the negative battery post, but to a grounding point on the engine.) Also, the ready indicator LED is not located where it’s easily seen. The state of charge displayed on the LCD screen. The manufacturer recommends charging at least every 3 months to keep it at the ready. There’s also a built-in flashlight with a optional strobe effect, and it has aUSB outlet for use as a power bank. A bonus would have been some kind of carrying case, but you’re on your own with that one.

   This product is superb. And it will really be there for you when you need it. This has enough power to start the car in an emergency and you can just put it in your emergency kit and it will be there for you when the time comes. Another thing you can use it for is powering your phone or tablet during a power outage emergency. And I did that recently and it worked perfectly for me. In fact the product powered my phone up from 40% to 100% in about an hour. So I really feel like this item is a great value and I highly recommend it. As a Vine reviewer I rarely give five star reviews but I feel this deserves one

   Handy portable charger. Charge batteries on the go, or keep it to use around the farm for tractors and riding mowers. Also has a charging port for your cell phone or other usb devices.

   Keeping this in my vehicle at all times for “peace of mind”. Hopefully will never have the need to use this but it will always be at the ready. The portable power supply is an added plus. Great gift for you young adult children.
