It includes a cigarette lighter socket and Type-C PD3.1 plus USB-A fast charging, delivering up to 140W on Type-C and 18W on USB-A (total limited by 5V3A when both ports are used). A 15W wireless charging pad adds convenience for Qi-enabled devices. This unit suits laptops, tablets, and power-hungry devices in workshops and field setups.
HiLetgo MP1495 Step-Down Module

The HiLetgo MP1495 module steps down DC 5–16V to various outputs, including 1.25V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V at up to 3A. It provides an adjustable voltage regulator power path suitable for low-voltage electronics, microcontroller projects, and battery-powered devices. The compact design makes it easy to integrate into RC builds or small control boxes where precise, reconfigurable voltage rails are beneficial for flight controllers and sensors.
Buying Guide
- Output range and current: Match the regulator to your device’s voltage requirements and peak current. For flight electronics, a stable 5V or 6V rail with at least 2–3A is common.
- Input compatibility: Check battery chemistry and voltage range (2S–5S and beyond). Higher input voltage can improve efficiency but may require heat management.
- Efficiency and heat: Switching regulators outperform linear BECs by reducing heat buildup, extending battery life and flight time in RC setups.
- Protection features: Look for over-current, over-temperature, short-circuit, and reverse-polarity protections to protect sensitive electronics.
- Output options: Multi-output units offer USB-C, USB-A, wireless charging, or XT60 connectors. Choose based on device needs and port availability on the field.
- Size and weight: For airframes, lighter and compact regulators minimize drag and weight penalties. Weigh options to preserve performance.
- Platform compatibility: Ensure the regulator’s presets or adjustable outputs align with your sensors, flight controllers, and receivers to avoid voltage mismatches.
- Installation and wiring: Consider screw mounting, plug-and-play connectors, and cable management to reduce vibration-induced wear in flight.
- Reliability under field conditions: Opt for units with robust thermal protection and protective enclosures if exposed to dust, moisture, or vibration.
- Future-proofing: Modules with adjustable presets and multiple outputs can accommodate evolving gear without swapping regulators.
