### ⭐⭐⭐⭐⭐ GREAT price and GREAT device!!!!!

GREAT price and GREAT device!!!!! already saved us just a few days after purchase. 84 year old mother doesnt remember she left the lights on while sitting in car for an hour. then this thing starts it right up! so easy to use... incredible! thank you :-)

### ⭐⭐⭐⭐⭐ Small but capable
*by C***N on March 12, 2026*

Smaller than I expected but works well. Started a Subaru Outback with a completely dead battery. But its internal battery power went from 100% to 40% During the starting process, so the advice in the user manual to make sure it is fully charged before trying to start a car with a dead battery is best heeded. I did note that when I went to recharge it after the dead battery start, it had rebounded to 85%. If you have USB charger that can provide 9 volts 2 amps, it recharges pretty quickly. If you only can provide 5V, it will take quite a while to recharge. Overall, I am quite pleased. It is compact and easy to use, and it works!
