## Customer Reviews

### ⭐⭐⭐⭐⭐ Keep the car charged
*by T***A on January 18, 2026*

Help keep the little car charged! Work great

### ⭐⭐⭐⭐⭐ Perfect
*by T***K on December 7, 2025*

Works great. Recommended.

### ⭐⭐⭐⭐⭐ Works on standard low cost RC car rechargeable batteries
*by J***N on January 22, 2026*

On Christmas day, our grandson got a low cost RC car (simple forward/backward/left/right), then promptly lost the charging cable. We were afraid it was some unique connector we'd never find. Turns out lots of this type of car (with a rechargeable battery) use the same connector (yeah). This works with his car. The Amazon listing has pictures of the connector, tells the voltage it supports, & how the charger works (kudos to seller). To see if it will work, make sure it's the right voltage, and look at the car's connector to see if it looks just like these ones.
