The LiitoKala Lii-100 Charger is a highly versatile and reliable single-slot charger designed to offer safe, intelligent, and efficient charging for a wide range of rechargeable batteries. Engineered with a focus on safety and convenience, the Lii-100 features advanced protective functions, including over-discharge protection, short circuit protection, smart battery identification, and reverse battery detection. These built-in safeguards ensure that batteries are charged correctly and efficiently while preventing common user errors that could otherwise damage the battery or charger.

The charger uses a constant current and constant voltage charging method, which is widely recognized for its ability to optimize battery performance and extend battery lifespan. By controlling the current and voltage throughout the charging cycle, the Lii-100 reduces the risks associated with overheating and overcharging, ensuring a safe and reliable operation. Its design is based around a micro-USB DC 5V input with a 1A power supply, making it compatible with a wide variety of power sources such as USB wall adapters, portable power banks, and laptops. This flexibility makes the Lii-100 an ideal travel companion and a perfect solution for users who need a charger they can use anywhere.

One of the key features of the Lii-100 is its ability to independently manage the charging process for a single battery. It allows users to select between two different charging currents, 500mA and 1000mA, depending on the specific needs of the battery being charged. The 500mA option is ideal for smaller batteries, ensuring a gentle charge that maximizes lifespan, while the 1000mA setting offers a faster charge for larger batteries without compromising safety.

The charger’s clear LED display provides real-time updates on the charging status, with indicators at 25%, 50%, 75%, and 100% to show the current progress at a glance. This intuitive visual feedback enables users to monitor the charging process easily and ensures that batteries are removed promptly once they are fully charged, protecting them from potential overcharging.

The LiitoKala Lii-100 is packed with additional safety features that make it a reliable choice for everyday use. Its anti-reverse function protects the device from damage caused by incorrect battery placement, while short circuit protection ensures that any faults are safely managed without harm to the charger or the battery. Overcharge protection stops the charging process once the battery reaches full capacity, safeguarding against overheating and battery degradation. Additionally, the 0V activation function can revive deeply over-discharged batteries, restoring functionality to cells that would otherwise be discarded, which can significantly extend the life of your battery investments.

In terms of technical specifications, the charger outputs a charging voltage of 4.2V ± 1% for lithium batteries and maintains a 5V output for USB applications. It offers selectable output currents of 500mA and 1000mA, with a cut-off current during constant voltage charging of less than 100mA. The external power supply standby current is kept below 15.0mA, ensuring minimal energy consumption when not in active use.

The Lii-100 Charger is compatible with a wide array of battery chemistries and sizes, including 3.7V Li-ion, 3.8V Li-ion, 3.2V LiFePO4, and 1.2V NiMH rechargeable batteries. Supported battery sizes include popular models such as 26650, 22650, 18650, 18490, 18350, 17670, 17500, 17355, 16340, 14500, 10440, AAA, AA, SC, and others, making it an indispensable tool for anyone who regularly uses battery-powered devices like flashlights, cameras, vape devices, and remote controls.

Compact and lightweight, the Lii-100 measures just 113mm in length, 38mm in width, and 32mm in height, and is made from durable plastic. Its small form factor and rugged construction ensure that it can withstand daily use while being easily portable for travel or outdoor activities. The practical design, combined with the safety features and broad compatibility, makes the LiitoKala Lii-100 a must-have charger for hobbyists, professionals, and everyday users alike.

Whether you need a reliable solution for charging your flashlight batteries, keeping your camera gear ready, or ensuring your everyday gadgets stay powered, the LiitoKala Lii-100 Charger offers the perfect combination of safety, efficiency, and portability. Its intelligent management system and user-friendly operation ensure that you always have power when you need it most, making it an essential addition to any battery care toolkit.
