Doublepow DP-B02 Universal 4-Slot Battery Charger

Product Overview

Doublepow DP-B02 Universal 4-Slot Battery Charger

Key Features

• Independent 4-Slot Architecture: The charger features 4 distinct charging bays. It allows you to charge 1, 2, 3, or 4 batteries simultaneously. You can also mix and match AA and AAA formats or different capacities across slots at the exact same time. [1, 2, 3]
• Integrated Protective Cover: Equipped with a built-in clear flip-down cover that safeguards the internal slots against airborne dust and debris when stored or left plugged into the wall. [1]
• Optimized Low-Current Output: Delivers a stable, lower-amperage stream that significantly keeps internal temperatures down. This slow-and-steady approach minimizes stress on individual battery structures to extend overall lifecycle and longevity. [1, 2, 3]
• Safety Engineering: Built out of premium, high-impact, fire-retardant plastic polymers. The charger integrates basic current controls to guard against overheating or sudden external shorts. [1, 2, 3]
• The Doublepow DP-B02 is a compact and budget-friendly 4-slot battery charger designed for standard 1.2V AA and AAA Ni-MH / Ni-CD rechargeable batteries. It features 4 independent slots, allowing you to charge anywhere from 1 to 4 batteries simultaneously, or mix AA and AAA sizes at the same time. Built with a protective clear dust cover, it delivers a safe, low-current stream (150mA for AA / 130mA for AAA) that helps prolong the overall lifecycle of your cells.

  ⚠️ Critical Operational Guidelines

  Because the DP-B02 is an entry-level standard charger, users must be aware of its specific functionality to prevent cell damage:

  1. Indefinite Indicator Lights: The red slot LEDs turn on immediately when a battery is introduced into an active slot under power. They will remain red indefinitely; they will not turn green, change brightness, or shut down automatically once charging is complete. [1]
  2. Manual Calculations Required: You must keep track of your plug-in times. The average recommended charging timeline sits between 8 to 10 hours depending on the cell capacity. Leaving cells inside the plugged-in cradle far past their limit can cause localized overheating and degrade cell performance over time.
