Unboxing and First Impressions
The VVCHG+ rechargeable AA batteries arrived in a neat, well-organized storage box. This is a significant improvement over other similar sets I've owned, showcasing a thoughtful design.
The packaging includes four AA batteries, a convenient 4-in-1 charging cable with a USB-C connector, and the storage case.
The batteries themselves feature a USB-C charging port, and the compact design makes them well-suited for many devices.
Charging and Safety Features
Charging is straightforward. The batteries charge quickly via USB-C using the included cable or any standard USB-C cable. A red light indicates charging status, turning solid red when fully charged.
The charging process takes approximately 1.5 hours. Importantly, these batteries boast a 1500-cycle lifespan. The batteries can charge up to 1.5 amps at 5 volts.
A built-in controller protects against over-current, overheating, and over-discharge—a crucial safety feature absent in older rechargeable battery technologies.
Capacity Test and Performance
The advertised capacity is 2200mAh at 1.5V (3300mAh). My tests showed slightly lower capacity: around 1880mAh was achieved, though this can vary depending on factors like the cutoff voltage and test setup.
Despite the discrepancy in capacity, the batteries performed well under load, maintaining a relatively stable voltage even at high current draws (up to 1.8 Amps).
The batteries fit snugly into the tight battery compartment of an Xbox 360 controller, indicating good physical compatibility.
Conclusion
The VVCHG+ USB-C rechargeable AA batteries offer a convenient charging method and a compact design which suits even tighter battery compartments.
While the actual capacity falls a bit short of the advertised 2200mAh, the performance under load is very impressive. The included safety features are a significant plus.
Overall, these batteries are a solid choice for users who prioritize ease of use, charging speed and the USB-C convenience, even with the slightly lower-than-advertised capacity.
