   Unit will not charge. Display shows 15% and when you plug it in to charge it automatically goes to 100%

   This jump starter is surprisingly small and lightweight. I easily keep it stored in my glove compartment, so it’s always there when I need it. It’s not just a jump starter! This device has multiple USB ports for charging my phone or other devices on the go. The built-in LCD screen keeps me informed on the battery level and jump start process.

   This little jump starter has saved my bacon a few times now! I’ve got an older car that likes to leave me stranded with a dead battery at the worst possible moments, but this gadget has gotten me back on the road every time. First off, the jumping power is impressive for such a compact unit. It’s rated for up to 4000A peak current, which is more than enough juice to start my 8-cylinder gas guzzler. It’s even supposed to work on diesel engines, but I haven’t had a chance to test that out myself. The dual USB ports are a nice bonus – I can charge up my phone or tablet while I’m waiting for a tow or killing time between jumps. The quick-charge 3.0 port is speedy, too. Topped up my smartphone from almost dead to 80% in under an hour! Safety-wise, this thing is packed with protections. Over-current, overload, over-voltage, overcharge – it’s got all the “overs” covered. Gives me some peace of mind when I’m hooking it up to my car’s delicate electronics. The built-in LED light is handy for nighttime emergencies. The SOS flashing mode is a nice touch – haven’t had to use it yet (knock on wood), but it’s good to know it’s there if I ever need to flag down some help. Now, the instructions could use some work. They’re a bit broken English and not always super clear. I managed to muddle through, but some better documentation would be a definite improvement. I also found the included jumper cables to be a bit short. They reach from the battery to the engine compartment on my compact car just fine, but if you’ve got a bigger vehicle you might need to get creative with your cable routing. Durability has been good so far, but I have my doubts about the plastic case holding up to really rugged use. It feels sturdy enough for occasional emergency use, but if you’re a mechanic or tow truck driver using it every day, you might want to invest in a beefier unit. All in all, I’m pretty satisfied with this jump starter. It’s gotten me out of a few jams (pun intended) and the extra features like the USB ports and LED light are welcome additions. Just don’t expect a bulletproof, professional-grade unit – it’s more of an “in case of emergency, break glass” solution for the average driver. Still, for the price and portability, it’s a solid pick in my book!​​​​​​​​​​​​​​​​
