Product Description
This bundle combines the compact white Delipow DLP-533 4-bay Type-C LED fast charger with high-performance Delipow AA 3404mWh 1.5V Pearl White rechargeable lithium batteries (available in 4-Pack or 8-Pack options). The DLP-533 charger features a modern Type-C input (DC 5V 2A), delivering an impressive 500mA charging current per slot for AA batteries and 400mA per slot for AAA batteries. It utilizes a precise 4.20V±0.05V cut-off voltage and a ≤100mA cut-off current, automatically stopping charging to prevent overcharging and significantly extending battery lifespan. Each slot is equipped with a clear green LED indicator that stays illuminated during active charging and automatically turns off or changes state once the batteries reach full capacity. The included 3404mWh AA batteries deliver a massive energy capacity, support 1.5-hour ultra-fast charging, up to 1500 cycles, and feature a premium Pearl White finish. This kit is the ultimate high-speed, high-capacity power solution for your smart home devices and high-drain electronics.

Frequently Asked Questions (FAQ)
Q1: What types of batteries does the DLP-533 charger support?
A1: The DLP-533 charger is specifically designed for 1.5V AA and AAA lithium-ion rechargeable batteries. It does not support 1.2V Ni-MH batteries or other battery types.
Q2: How long does it take to fully charge the included 3404mWh AA batteries?
A2: Based on the charger's 500mA per-slot output and the standard charging formula (Capacity × 1.25 ÷ Current), it takes approximately 1.5 hours to fully charge a 3404mWh AA battery.
Q3: What do the green LED indicators mean on this charger?
A3: The green LED light stays illuminated while the battery is actively charging. Once the battery reaches full capacity, the charger automatically stops and the LED turns off or changes state, indicating it is ready for use.
Q4: Are these batteries ready to use right out of the box?
A4: Yes, they come pre-charged from the factory and are ready to use immediately. If they have been stored for a long time, we recommend giving them a full charge before first use to achieve maximum runtime.
Q5: Why is the 4.20V cut-off voltage used for 1.5V lithium batteries?
A5: Although these batteries are labeled 1.5V, 1.5V AA/AAA lithium batteries reach full saturation at 4.2V. The DLP-533 uses a precise 4.20V±0.05V cut-off to fully charge these cells safely and optimally.
