Description:
This battery size conversion adapter is an innovative power supply solution that supports converting AA/AAA batteries to D/C/AA sizes, solving the problem of equipment shutdown caused by mismatch in battery specifications. The adapter adopts a high-toughness ABS plastic shell + gold-plated electrode contact design, which is highly compatible, safe and durable, and is suitable for home emergency, outdoor travel, toy modification and other scenarios.
Flexible conversion of multiple sizes (one device and multiple use)
Adaptation mode:
AA→D/C: 1 AA battery is converted to D/C size (requires series boost, and the output voltage matches the target battery).
AAA→AA/C: 1 AAA battery is converted to AA or C size (compatible with low power consumption devices).
Modular structure: The adapter is embedded with a removable sleeve, and D/C/AA size switching is achieved by replacing the sleeve.
Anti-reverse connection design: Automatic power off when the battery polarity is incorrect to avoid short circuit and burn the equipment.
Overload protection: Maximum load current ≤1.5A (continuous), triggering the fuse mechanism during overload.
Engineering-grade material and structure
Case: Flame-retardant ABS plastic (UL94-V0 certification), high temperature resistance (-30℃~80℃), anti-fall and pressure resistance.
Electrode contacts: gold-plated copper sheet (resistance ≤0.05Ω), reducing energy loss and extending battery life.
Compact design: The single adapter weighs only 15g, the storage volume is ≤5cm³, portable and without burden.
Application scenarios
Emergency power supply: When D/C battery equipment is out of power, use AA/AAA batteries temporarily to replace them (such as flashlights, radios).
Children's toy modification: convert high-cost D/C battery toys into AA/AAA drivers, saving long-term use costs.
Outdoor lightweight: reduce the size of carrying batteries when hiking and camping, and use multiple uses for one thing.
Electronic experiment: compatible with breadboards and powers modular circuits with different voltage requirements.
