The Regatta Heated Jacket Battery Pack delivers reliable portable power engineered for extended outdoor use and heated apparel applications. With a substantial 5000 mAh capacity, it provides sufficient energy reserves for sustained heating performance across demanding conditions. The dual USB-A output ports (5V DC 2.1A each) enable simultaneous charging of multiple devices or heated elements, offering flexibility for complex power requirements. Advanced battery management technology ensures safety and longevity across all operating conditions. Comprehensive protection mechanisms include overcharge and discharge safeguards preventing battery degradation, overvoltage and overcurrent protection shielding connected devices from electrical damage, and short-circuit protection eliminating hazard risks. Thermal management features—over and under temperature protection—maintain optimal performance across extreme environmental conditions, whilst loop-back protection prevents reverse-current damage. The Li-Polymer battery chemistry delivers consistent power output with minimal self-discharge, ensuring reliable performance when needed most. Micro-USB 5V DC 1A input enables convenient recharging from standard power sources, wall adapters, or portable chargers.
