Review: Fantastic Car Jump starter 👍👍👍 - I had purchased the FNNEMGE 2000A in 2023 as I was having car battery trouble...however the car battery issue was sorted out and FNNEMGE arrived a little after that, hence I never got to use it. Well all I ever did with it was to regularly check it and if required then charge it, that to just a bit because the charging would never come down as it wasn't being used.. So today I'm writing this feedback after two years because for some reason my car battery drained out and was totally dead...I pulled out the Jump starter...fixed it up to the battery terminals..turned on the power button and turned the car key on....and Hola!!! The engine roared to a great start...😊😊 No waiting, no charging and no time pass...just connect and start your engine. I'm very impressed and feel very confident to have a handy product like this in my car, which could get me out of a sticky situation maybe in the future. I highly recommend this product to all those car owners especially owning automatic cars...Cheers & Kudos to desertcart for getting us a world class handy product...Keep up the good work...👍👍👍
