Product Description

Keep your essential devices powered with the  Devaji Intelligent USB Battery Charger. This compact, single-slot charging solution is designed for maximum portability and broad compatibility. At Robogears, we recommend this smart charger for its "intelligent" circuitry, which automatically detects the battery type and adjusts the charging current accordingly. Whether you need to charge high-capacity AA lithium cells for a digital camera or AAA Ni-MH batteries for a TV remote at your Pimpri facility, this USB-powered adapter offers a convenient way to charge via power banks, laptops, or standard mobile chargers. Its lightweight design makes it an ideal addition to any travel kit or hobbyist's workbench.

Detailed Key Features

  • Intelligent Microprocessor Control: Automatically monitors the battery status and terminates the charging process once the cell is full to prevent overheating.

  • Universal USB Power Input: Features a standard 5V USB input, allowing you to charge your batteries anywhere there is a USB port available.

  • Compact & Portable Form Factor: The sleek, single-slot design is easy to carry in a pocket or toolkit, making it perfect for on-the-go maintenance.

  • Smart LED Status Light: A dedicated LED provides instant visual feedback, turning from red to green to signal a completed charge.

  • Multi-Chemistry Support: Versatile internal circuitry is compatible with a wide range of rechargeable technologies, including Li-ion and Ni-MH.

All Technical Details

  • Spring-Loaded Contact: Features a durable, adjustable spring contact to securely hold both AA and AAA battery sizes.

  • Protection Suite: Built-in safeguards protect against reverse battery insertion and short-circuit conditions.

  • Heat Dissipation: Designed with ventilation gaps to ensure the battery remains cool during high-current charging cycles.

  • Efficiency: High-conversion efficiency reduces energy waste and shortens charging times for high-capacity cells.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Match the Input: To ensure the fastest charging at your Pimpri workshop, connect this charger to a USB port or wall adapter rated for at least 1.0A. Using a lower-power port (like those on older desktop PCs) may increase charging time.

  • Single-Cell Logic: Since this is a single-slot charger, it is perfect for devices that use an odd number of batteries or for topping up a single backup cell while the others are in use.

  • Contact Care: To maintain optimal charging speed, occasionally wipe the metal contacts with a cloth dampened with IPA (Iso-Propyl Alcohol) to remove any oil or oxidation buildup.

  • Chemistry Warning: Always verify that your battery is labeled "Rechargeable." Attempting to charge standard alkaline or carbon-zinc batteries can lead to leakage or fire.

Package Includes

  • 1 x Generic Intelligent USB Battery Charger (Single Slot)

  • 1 x USB Power Cable
