HOYOA, a professional integrated supplier of lithium battery applications, today announced the simultaneous release of two innovative devices: the 21V 200W Power Inverter and the 21V 300W Car Battery Charger. Utilizing high-capacity 21V lithium tool battery platforms, this powerful duo provides a complete energy solution for outdoor enthusiasts, remote workers, and motorists facing road emergencies.
By converting tool batteries into both standard AC power outlets and a high-current automotive rescue system, HOYOA bridges the gap between everyday productivity and emergency vehicle recovery.
Product 1: HOYOA 21V 200W Power Inverter — Your Mobile Workstation Partner
Designed to keep laptops, drones, and camera gear running anywhere, this compact inverter transforms 21V battery packs into a versatile mobile charging hub.
Household AC Power: Delivers 120V AC (60Hz) power up to 200W for small electronics.
65W Fast Charging: Features a high-speed USB-C Power Delivery (PD) output supporting up to 65W — perfect for modern laptops without bulky adapters.
Bi-Directional Charging: Offers a 45W USB-C input for rapid system recharges, alongside an 18W USB-A fast-charging port.
Product 2: HOYOA 21V 300W Car Battery Charger — A Reliable Roadside Helper
Say goodbye to relying on another car for a jump-start. This dedicated charger uses your 21V lithium battery to directly revive dead 12V car batteries.
High-Current Recovery: Delivers a steady 13.5V/30A output (approaching 405W peak capability) to quickly charge and restore vehicle batteries via heavy-duty smart clamps.
Cordless Independence: No need to position two cars bumper-to-bumper; simply hook up the clamps, connect your tool battery, and charge on the spot.
Shared Family Features
Both units adopt HOYOA’s latest industrial-grade design, ensuring durability and ease of use in field scenarios:
550-Lumen LED Floodlight: Each device features a built-in, adjustable panel light with up to 550 lumens, illuminating dark engine bays and campsites efficiently.
Ergonomic Mechanical Handle: Available in distinctive color accents (tactical blue, crimson red, and high-visibility yellow) for quick identification and easy carrying.
Multi-Layer Safety Systems: Engineered with multiple safety protections against over-current, short-circuiting, and reverse polarity.
“Our goal at HOYOA is to maximize the utility of lithium battery technology,” said a HOYOA Product Director. “With the 200W Inverter and the 300W Car Battery Charger, a single 21V battery pack can now run your laptop during the day and rescue your vehicle at night. It is an ideal solution for drivers and outdoor enthusiasts.”
