### ⭐⭐⭐⭐⭐ Works like a champ.
*by L***T on April 11, 2025*

My 2022 KIA sportage car battery was bad, but I couldn’t yet afford to replace it. This bad boy jumped my car everytime I needed to get it started for a little over a week. Is it top of the line? No. But it works. And it also acts as a spare battery if you have a cord with a usb-A end to plug into it. Idk how long this gadget will last, but for the price and utility? Worth every cent.

### ⭐⭐⭐⭐⭐ Very useful product!!
*by G***A on June 24, 2025*
