Product Description
The Delipow DLP-S405 is a high-performance 4-bay smart charger featuring an intuitive green LCD screen, designed to deliver efficient and safe charging for AA and AAA Ni-MH/Ni-CD rechargeable batteries. Powered by a standard DC 5V 2A USB input, it provides a rapid 400mA charging current for AA batteries and 350mA for AAA batteries. The charger utilizes a cutting-edge two-stage charging algorithm: it fast-charges the battery to 95%, then intelligently switches to a 70mA trickle charge mode to fully saturate and protect the battery. Built-in 1.48V±0.05V precision cut-off voltage ensures batteries are never overcharged, significantly extending their lifespan. With an LCD screen that displays real-time charging status and battery levels, and a sturdy LG flame-retardant casing, the DLP-S405 offers a reliable, safe, and visually intuitive charging experience for your household electronics.
Key Features
-
Intelligent LCD Status Display: The bright green LCD screen clearly shows the charging status and battery level for all four slots simultaneously. The battery icons dynamically display levels from 0-30%, 30-60%, and fully charged, making the charging process easy to monitor.
-
Fast Charge to 95% & Trickle Finish: Employs smart charging technology. The charger delivers a high current to rapidly charge the battery up to 95% capacity, then automatically switches to a 70mA trickle current to safely top off the battery to 100%, preventing overcharging and prolonging battery life.
-
High-Speed 4-Slot Independent Charging: Powered by a DC 5V 2A USB port, it delivers 400mA per slot for AA batteries and 350mA per slot for AAA batteries. It features 4 independent channels, supporting one to four AA/AAA Ni-MH / Ni-CD batteries.
-
Precision Voltage Cut-off: Built-in smart IC chip ensures a highly accurate charging cut-off voltage of 1.48V±0.05V and a cut-off current of ≤100mA. This precision prevents overcharging, reduces heat, and maximizes battery lifespan.
-
Multiple Protections & LG Flame-Retardant Shell: Constructed with premium LG high-strength flame-retardant plastic, ensuring high temperature resistance and impact durability. Equipped with over-temperature, over-charge, over-voltage, and over-current protection for ultimate safety.
-
Constant Voltage Charging Design: Utilizes smart IC control to maintain a constant voltage output, ensuring efficient and stable power delivery while safeguarding against over-charge and over-discharge risks.
-
Versatile USB Power Input: Easily powered via laptops, standard phone adapters, power banks, or car chargers. (Note: USB cable is for power supply only; data transfer is not supported).

Frequently Asked Questions (FAQ)
Q1: How long does it take to fully charge an AA battery with this charger?
A1: Based on the 400mA output and the standard charging formula (Capacity × 1.25 ÷ Current), it takes approximately 4.1 hours to fully charge a 1300mAh AA battery, and approximately 10.3 hours for a 3300mAh AA battery.
Q2: Can I charge AAA batteries with this Delipow charger?
A2: Yes, the DLP-S405 charger supports both AA and AAA 1.2V Ni-MH / Ni-CD batteries across all 4 slots, outputting 350mA per slot for AAA batteries.
Q3: What does the LCD screen display during charging?
A3: The green LCD screen displays the real-time charging status. You can clearly see when a battery is charging (0-30%, 30-60%) and when the battery reaches a full charge. If a battery is defective or inserted incorrectly, the screen may display an error indicator (Error or CHG status).
Q4: What is the advantage of the "Fast Charge to 95% then trickle charge" mode?
A4: This algorithm balances speed and battery health. It delivers high current for the bulk of the charging (up to 95%) to minimize your waiting time, then switches to a low 70mA current to gently complete the final saturation, preventing overheating and extending your battery's overall lifespan.
Q5: Is it safe to leave batteries on this charger overnight?
A5: Yes. The charger features a precision 1.48V cut-off voltage. Once the battery reaches full capacity, the charging process automatically stops, preventing overcharging and ensuring safety.
