TN269 2-Bay 18650 / 18500 / 14500 Li-Ion Battery Charger
For anyone who relies on portable electronics powered by Li-Ion batteries, the Tenergy TN269 2-Bay Li-Ion Battery Charger represents an excellent balance of speed, efficiency, and safety. This charger is designed to cater to the charging needs of popular battery sizes such as 18650, 18500, and 14500, all operating within a 3.6V to 3.7V range. Whether you use these batteries in flashlights, vaping devices, portable fans, or other everyday gadgets, the TN269 offers a reliable and user-friendly solution to keep your devices powered and ready for use.
Versatility and Compatibility
At its core, the Tenergy TN269 charger is engineered to work with 3.6V/3.7V Li-ion batteries, making it compatible with a wide array of devices that depend on these battery types. The charger supports the 18650, 18500, and 14500 battery formats—a versatility that is particularly beneficial for users who utilize different battery sizes for different applications. Instead of needing separate chargers for each battery type, you can depend on the TN269 to handle them all. This consolidation not only saves desk or travel space but also simplifies your charging routine, ensuring that you always have the right tools at your fingertips.
Dual-Channel Independent Charging
One of the standout features of the TN269 charger is its dual independent charging channels. Each bay is equipped with its own charging circuitry, which means that the charger can detect, monitor, and manage the charge of each battery separately. This independent operation ensures that every battery in each bay receives the optimal charging current regardless of the charge status of the other battery. For example, if one battery needs a full charge while the other is nearly full, the charger will adjust its output accordingly for each channel. The end result is a more balanced, efficient, and safe charging process.
Fast and Efficient Charging Rate
Time is of the essence in today’s fast-paced world, and the TN269 doesn’t disappoint when it comes to charging speed. Each channel outputs a regulated 4.2V at a current of 1000mA, allowing for a charge rate of 1A per battery. With such a configuration, you can fully charge a typical 2600mAh battery in approximately 2.5 hours. This relatively fast charge time is made possible by the constant current and constant voltage charging modes. In the early stages of the charge, the constant current mode delivers a steady flow of energy. Then, as the battery nears full capacity, the charger smoothly shifts to a constant voltage mode, ensuring that the battery is filled to the optimal level without overcharging.
Safety Features and Protection
Safety is a primary concern when charging lithium-ion batteries, and the TN269 is equipped with several important features that minimize risks and extend battery life. One of these key safety features is reverse polarity protection. If a battery is inserted with the wrong orientation, the charger’s built-in sensors immediately detect the error. In such cases, the charging process is automatically terminated, and an LED indicator flashes red to alert the user of the issue. This proactive measure helps prevent potential battery damage, overheating, or even more serious hazards such as battery failure.
Additionally, the charger’s use of constant current and constant voltage charging modes ensures that each battery is charged under ideal conditions. The early stage constant current phase avoids overly rapid charging that might stress the battery, while the subsequent constant voltage phase prevents the battery from being charged beyond its capacity. These mechanisms collectively protect the battery’s integrity, preserve its overall lifespan, and promote consistent performance over multiple charge cycles.
Universal Input and Convenient Design
The Tenergy TN269 is designed to work with a universal AC voltage range between 110V to 240V. This wide input voltage compatibility means that the charger can be used in almost any country without the need for voltage converters, making it an excellent travel companion for those who are frequently on the go. When connected, the charger transforms the supplied AC voltage into a steady DC output of 12V at 1000mA, which feeds its two charging bays with a reliable supply of energy.
Portability is another hallmark of the TN269. With its compact dimensions and lightweight design, the charger is easy to pack into travel bags or store on a clutter-free work desk. Its straightforward layout and intuitive LED indicators allow users to quickly determine the status of their batteries—whether they are charging correctly or if there is an error. This ease of use makes the TN269 suitable not only for home use but also for fieldwork, where dependable power sources are crucial.
