Introduction

The STRME5657 LCD Display 4-Slot Intelligent Battery Charger for AA/AAA Rechargeable Batteries arrived on my desk promising efficient and intelligent charging for my ever-growing collection of rechargeable batteries. This review details my experience using this US plug black model over several weeks, putting it through its paces with various battery types and charging scenarios.

Features

The STRME5657 boasts a compact and sleek design. Its four slots allow for simultaneous charging of both AA and AAA batteries. The LCD display provides clear and concise feedback on the charging progress of each battery, including voltage and charging status. The intelligent charging system automatically adjusts the charging current to prevent overcharging and damage to the batteries. The build quality felt surprisingly robust for a charger at this price point, using what appears to be durable plastic.

Performance

I tested the STRME5657 with a variety of AA and AAA rechargeable batteries, including NiMH and NiCd types. The charging times were consistent with the manufacturer’s specifications, and the LCD display accurately reflected the charging progress. I particularly appreciated the individual slot monitoring; it allowed me to identify a weaker battery that wasn’t holding its charge as well as the others. During the testing phase, the charger remained cool to the touch even after extended use, a positive indicator of its efficient design. The trickle charging feature is a welcome addition, ensuring fully charged batteries are maintained without damage.

One minor observation: while the charger handles a variety of battery types, it doesn’t seem to support Li-ion batteries, which is a limitation for some users. The included instructions were clear and straightforward, though a more detailed troubleshooting section would have been helpful. The overall charging speed was impressive and consistent across different battery types, exceeding my initial expectations.

Pros & Cons

Pros:

• Compact and stylish design.
• Simultaneous charging of AA and AAA batteries.
• Clear LCD display with individual battery monitoring.
• Intelligent charging system prevents overcharging.
• Relatively fast charging speed.
• Robust build quality.

Cons:

• Does not support Li-ion batteries.
• Instruction manual could include more detailed troubleshooting information.
• Limited color options (only black).

Final Verdict

The STRME5657 LCD Display 4-Slot Intelligent Battery Charger is a solid performer that offers excellent value for money. Its intelligent charging system, clear display, and compact design make it a convenient and reliable solution for charging AA and AAA rechargeable batteries. While the lack of Li-ion support might be a deal-breaker for some, for those primarily using NiMH and NiCd batteries, this charger is a highly recommended choice. I would definitely purchase this charger again and recommend it to friends and family.
