FNNEMGE Car Jump Starter, 6000A Peak 26800mAh Car Battery Starter(Up to All Gas, 10.0L Diesel Engine), with USB Quick Charge 3.0,LED Light, EC-5 Output. …

Haven't used for months. Sat in boot. Had to jump-start my 4L jeep today 3 times using it. It still had 85% after months and after successfully starting the jeep 3 times today it finished on 85%. It is expensive but it definitely is a quality product and saved me today.

As soon as u disconnect the jumper from the charger, the battery shows zero percent charge. Battery is defective and dies in 1 second!!!! I could never use it

Long lasting easy to use and life saver A must have

Applying for refund/replacement..the delivered unit looks new but is of extremely poor quality. It takes hours to get charged and minutes to drain just by charging mobile phone .. Note: If the purpose is to jump start the vehicle then it works perfectly as the car gets started well and even the battery is not drained at all after jump starting, in my case I started Honda Pilot and the battered remained 100% after first start. However if the purpose is multi use then forget it: I tried to charge the mobile via USB slot or even simply swithing on the torch the battery drains supper fast (100% to 10% in less than 20 minutes) and then it will take atleast 2 hours to charge the device back itself

Worthy of the amount, wouldn’t need a replacement for a long time

I had jump leads in the car for a long time, and this unit has replaced them. It packs a big punch for something so small and neat. Easy to use and easy to recharge, although in truth it's held the charge for a long, long time before that became a worry. The case is compact and tidy. A very good buy.

Its good but take long time to charge and its not more then 500 mah

works good

08/02/2026 On Saturday I tried to install a dash cam for my Pathfinder and I had the car's power on for a while without starting the engine, just to test the dash cam. Little did I know that was enough to drain the battery that the car could no longer start. I used a multimeter to check the voltage of the battery and it read 11.95. So I decided to get a jumpstarter to fix the problem. After an hour of questioning AI and browsing Amazon, I decided on this FNNEMGE 6000A, which is relative cheaper than the other brands in the similar AMP range. Yes, some negative reviews did have me concerned but still decided it was worth a try. I paid the postage for next day delivery as we definitely need to use the car on Monday. Today (Sunday) it arrived in the afternoon, and was 87% charged. I played a bit with the led light functions which dropped it to 86% after just a minute or so. Then I spent a couple of hours charging it up to 100%. Before jump starting the car, I test the car battery's voltage again but the multimeter picked up no votage at all. I thought this was no good, but the car could still unlock without using the physical key so I think the battery should still hold some power. On first attempt of jumpstart, the car did not start, and I got quite worried. I followed the instruction manual to disconnect the jump start for a minute or so, while I checked the car battery's voltage again and this time the multimeter picked up 11.15 volts. That's a good sign! On second jump start attempt, the car successfully started. While I thought that would take out some juice from the starter, it still show 100% charged. I then took the car out for a spin and test the battery again. The multimeter reads 13.7+ volts. All good now! Writing this review on first day of using the starter because I don't know when will be the next time I use it. But I'll probably check its status again after a few days to see if it is loosing charge without use. Update 12/02/2026 It seems like the battery might have reached its life expectancy. It was all good on Monday. Then on Tuesday the car wouldn't start again. Since then, we've been using this jumpstarter each time we needed to start the car. Have used it about 5 times now. The LCD still shows 99% which means its holding the power well (if the reading is correct.)

Good product and value for money

ممتاز وانصح به

At first I was a bit skeptical whether or not this particular jump starter was gonna be the right purchase, mainly cause I’ve never heard of the brand/company before. But boy was I wrong. This is not the first jump-starter that I’ve ever owned but in fact is the 3rd one. I tried testing this new one on my 6.0 liter work truck to get an idea how well it worked. In the past I when I tried using the other two jumper boxes on this same truck, it gave me some trouble as they would struggle when attempting to jumpstart my truck. However pleasantly to my surprise this one has no hesitation at all and turned the engine over immediately. I was also surprised to find out that this one has the ability to wirelessly charge my iPhone and also included attachment to provide a 12v power outlet like the ones found in a car. As long as this thing lasts the test of time, it gets my vote of approval.

Great product! Bought 2 for Father’s Day for husband and dad. My dad has already used it on two lawn mowers and said it works fantastic and started them instantly!
