Review: 🔋Jump a dead car in less than 1 minute! ⚡️ - I already used it about 10 times! I live near Milwaukee so January and February can be brutal on car batteries (especially Walmart batteries)! I have multiple vehicles so sometimes my cars sit for over 5 days. Ok I was skeptical on buying this because the price was less than half of the popular ones. But I read a few reviews and took a chance. When battery was dead I hooked it up and instant ⚡️POWER ⚡️! Even when my dad's Lexus wouldn't start with traditional jump box, this thing did the job. (His car has electrical issues.) It's easy to charge, just use basic USB-C cable. I recommend using ur own USB cable because the included one is not Great. Even after several jumps the charge is almost full. I used to charge it after each use. Now I'm waiting to see how long it takes to drain the charge. You don't need the expensive units. This will do everything u need it to do. The carry case is great.
Review: Worked perfectly. Will get one for each vehicle. - Within a couple of days of receiving this, someone at my bar had a dead battery. It was a large pickup truck. Started it within 2 seconds. Much more convenient than pulling a vehicle around to hook up jumper cables. Will buy more. Cannot beat the deal at less then $30. Update: Needed to use it 5 times so far. Starts everything within a couple seconds. Today I had to use it on a large diesel truck. The owner said it will never start it. Couple seconds and it fired right up. Few days ago, the battery on my large 6-cylinder diesel generator was dead. Again, fired up in second. 5 starts with it and still shows full charge on the indicator. I've already purchased another one for my dad. He has a farm, and something always has a dead battery lol
