18650 Battery Charger 4-Bay for Rechargeable Batteries

The GRACETOP Smart Battery Charger offers an enhanced product experience by addressing the common problems associated with traditional chargers. The old charger's use of 110V voltage posed a fire risk, and the incompatible power plugs required different adapters in different countries, which was highly inconvenient.

The new GRACETOP charger addresses these issues. It operates at a safe 5V voltage, eliminating the fire hazard and making it suitable for use around children. The USB port design allows the charger to be used in a wide range of environments, such as with power banks, car adapters, computers, and USB power adapters.

The charger's slider design supports a variety of battery sizes, including 18650, 14500, and 16340 batteries. However, it does not support 26650 batteries or 1.2V AA/AAA batteries, nor can it activate 0V batteries.

The product features built-in safety protections against overcharging, overheating, overvoltage, and short circuits. The charger's indicator lights show the battery's charging status, with red indicating charging and green indicating a full charge.

The GRACETOP charger is compatible with various 3.7V lithium-ion batteries, such as 18650, 18490, 18350, 17670, 17500, 16340, and 14500. It does not support charging alkaline batteries.

The microprocessor-controlled charging process automatically stops when the batteries are fully charged, and the charger also features reverse polarity and short circuit protection, ensuring the safety and health of the batteries.

The package includes the USB 18650 battery charger and an English user manual. The charger can simultaneously charge up to 4 batteries, with the appropriate voltage and charge mode automatically selected based on the battery status.

Overall, the GRACETOP Smart Battery Charger offers a safe, versatile, and efficient charging solution, addressing the common issues associated with traditional battery chargers.
