Submersible Charging & Power for Underwater Devices | Hovell Tech
Underwater Charging Solutions
Designed for the extreme. Our underwater charging solutions enable safe, efficient, and sealed power transfer for marine electronics, diving devices, and subsea robotics.
Industry Challenges
Why Charging Below Water Is a Technical Minefield
Underwater operations demand absolute reliability, extreme safety, and total sealing — but standard electronics fall short. Here are the top challenges your clients face:
Water Intrusion Risks
Saltwater, pressure, and corrosion damage traditional ports and contacts.
Mechanical Connectors Are Weak Links
Traditional cable interfaces wear out, leak, or break under movement and pressure.
Charging Through Enclosures Is Difficult
Devices are sealed for protection — but hard to access for power.
Limited Real-Time Power Transfer
Difficult to maintain continuous operation without surfacing.
Custom Form Factor Constraints
No off-the-shelf charger fits custom-shaped diving or ROV devices.
Engineered Charging for the Uncompromising Demands of the Deep
At Hovell Tech, we develop sealed, submersible, and pressure-resistant charging systems tailored to harsh underwater environments.
Inductive Wireless Charging (Through Plastic/Glass)
No mechanical contact points; power transfers through sealed casings.
Custom Magnetic Connectors (Waterproofed)
Easy blind-mating underwater with auto-alignment; no exposed pins.
Pressure-Resistant Module Designs
Engineered for depths up to 100m+ with full waterproof certification (IP68+)
Custom Power Profiles (5V–24V, 10W–50W)
Adapted to your device’s battery and runtime requirements.
Form Factor Customization
Design integration into diving gear, underwater tablets, ROV bodies, or sensors.
