MINI POWER CONVERTER ADAPTER FPV BATTERY → USB-A mini QC3.0 / QC2.0 (Compact Version)

1. General Description The converter adapter is designed to convert voltage from FPV LiPo batteries into stabilized USB power for powering and charging portable electronic devices in field conditions. The adapter is based on a step-down (buck) DC-USB converter supporting QC3.0 / QC2.0 (Version V2). The product is targeted at mobile units where compactness, minimal weight, and rapid deployment are critical.

2. Intended Use The adapter is designed for:

• Powering and charging USB devices (smartphones, radios, GPS, flashlights, etc.);

• Use with FPV LiPo batteries in field and combat conditions;

• Situations where voltage monitoring is performed by external means or according to protocol. The adapter is not intended for charging the source batteries.
