This is the high-performance battery charger "X4" from Hitec. It's a convenient model that can charge up to four AA or AAA NiMH batteries simultaneously, and it efficiently charges each slot independently. I used it for Mini 4WD, and it can handle everything you need for that. It comes with an LCD display, allowing you to check voltage and charging status for safe and worry-free use. It makes it easy to understand the battery's condition, making it a very practical charger for those who regularly use rechargeable batteries like Eneloop. An AC adapter is also included, so you can start using it right away upon arrival. ⭐︎Operation has been confirmed. Recommended for those who use a lot of batteries, such as for Mini 4WD, RC cars, cameras, game consoles, LED lights, etc. Since a new charger of this caliber is quite expensive, this is a great deal for anyone looking for a good quality used one. Please check the photos for the condition. ※Batteries shown in the photos are not included. Thank you.
