Case Study: Rapid Drone Deployment and Extreme-Environment Charging for Search & Rescue Operations
A county Search & Rescue (SAR) fleet relies heavily on advanced thermal imaging drones and high-powered mobile command stations to locate missing persons across vast, challenging terrains. From dense forestry to expansive deserts, these rescue missions occur in environments where ground visibility is near zero, making aerial thermal technology the most critical tool at their disposal.
Challenge – Powering High-Drain Drones and Offloading 4K Data in Extreme Environments
When operators return to the command vehicle, they face a severe bottleneck: offloading massive 4K and thermal video files while simultaneously fast-charging high-capacity drone batteries. The rescue drones feature complex sensing systems—omnidirectional binocular vision, laser rangefinders, and 640×512 thermal radiometric sensors—which draw substantial power.
Standard consumer-grade chargers and hubs were repeatedly failing. Extreme heat during the summer and freezing blizzard temperatures compromised the hardware, and the constant vibration of the off-road vehicles caused standard USB connections to disconnect or break. Furthermore, attempting to charge multiple high-drain batteries concurrently caused massive voltage drops and often tripped the command vehicle’s alternator, effectively grounding the fleet when every second counted.

Solution – Industrial-Grade USB Power Delivery Integrated for Mobile Command
To build a rugged, dependable mobile command center, the SAR team required industrial-grade connectivity that could handle fluctuating power sources, extreme temperatures, and high-wattage outputs. They integrated Coolgear’s robust Power Delivery (PD) solutions directly into the custom dashboards of their rapid response vehicles.
4-Port 240W USB 3.2 Gen 2 PD 3.0 Hub w/ 60W PD Upstream & ESD Surge Protection
Primary Charging Station: The team integrated the 240W 4-Port Type-C PD Charging Station. Capable of intelligently allocating high-wattage power, it allows four separate devices to fast-charge simultaneously off the vehicle’s 12-24V DC battery without overloading the system.
3-Port 180W USB 3.2 Gen 2 PD 3.0 Hub w/ 60W PD Upstream & ESD Surge Protection
Rapid Data & Power Hub: To interface with the primary command laptops, they deployed the 3-Port 180W USB 3.2 Gen 2 PD 3.0 Hub (w/ 60W PD Upstream). This allowed operators to transfer gigabytes of high-res thermal imaging data at 10Gbps speeds while simultaneously providing 60W upstream power to keep the laptops running. Its 15kV ESD surge protection secured the sensitive equipment from electrical spikes.
280W Dual 140W USB-C PD 3.1 Charger – World’s Most Powerful Surface Mount Charger
Ultra-Fast Drone Recharging: For the largest, highest-drain multi-rotor drones, the vehicles were outfitted with the ChargeIT! Mini 280W Dual USB Type-C PD Charger. Utilizing Extended Power Range (EPR), it delivers a massive 140W per port. The variable voltage input seamlessly handles the fluctuations of the vehicle’s power supply, buck-boosting it up to 28V to guarantee the drones recharge in record time.
Benefits – Keeping the Fleet Airborne and Maximizing Rescue Potential
The transition to industrial-grade power delivery resulted in zero hardware downtime. The Coolgear solutions’ wide operating temperature range (-20°C to 75°C) and rugged metal enclosures ensured flawless operation, whether the truck was parked in a snowstorm or baking in the desert sun.
With 15kV ESD surge protection preventing electrical damage and intelligent PD allocation managing the load on the vehicle’s alternator, operators no longer had to worry about power bottlenecks. Drones spent less time tethered to the command vehicle and more time in the air. By keeping their most valuable asset flying, the SAR team successfully expanded their coverage capabilities, ultimately leading to faster response times and safer recovery missions.
