Ecarke 200W Power Inverter for Makita 18V Batteries

The Ecarke 200W Power Inverter converts a Makita 18V tool battery into a compact, on-the-go power station with an AC outlet, USB-A, USB-C ports, and an integrated LED work light.

Built to turn familiar Makita 18V lithium-ion batteries (sold separately) into a versatile power source, this inverter supplies up to 200 watts of 110–120V AC power while also offering fast-charge USB-A and USB-C outputs. Its fan-cooled design and multiple safety layers protect both the battery and connected devices, and the built-in adjustable LED makes it useful on job sites, in campsites, or during household power interruptions.

How much power can I expect and what devices will it run?

This inverter provides a continuous 200W AC output at 110–120V, suitable for low- to moderate-draw electronics. It will reliably run laptops, cameras, LED lamp heads, small fans, and charge smaller appliances; it is not intended for heavy loads like full-size power tools or space heaters.

• AC outlet: 110–120V, up to 200W continuous output
• USB-A ports: two 5V/2.1A outputs for phones and accessories
• USB-C port: 5V/3A (up to 20W) for tablets and fast-charging phones
• Not for high-wattage devices (motors, heaters above 200W)

Which Makita batteries are compatible and is any adapter required?

The Ecarke inverter is designed to accept a range of Makita 18V lithium-ion batteries directly—no extra adapter needed. Common compatible models include BL1830B, BL1860B, BL1820B, BL1840B, BL1850B and similar 18V packs; always confirm physical fit and specifications before use.

• Direct compatibility with Makita 18V tool batteries (battery not included)
• No additional adapter or cradle required for supported battery types
• Check battery charge level for available runtime estimates
• Battery model list: BL1830B, BL1860B, BL1820B, BL1840B, BL1850B, etc.

What safety and durability features protect the inverter and battery?

Ecarke built this inverter with layered protections and active cooling to preserve both the battery and your devices. A smart fan runs as needed to dissipate heat, while electronic safeguards cut power in cases of overload, short-circuit, extreme voltage, or battery over-discharge.

• Thermal management: intelligent fan-cooling to prevent overheating
• Electrical safeguards: overload, short-circuit, over/under-voltage protection
• Battery protection: anti-over-discharge to preserve battery life
• Durable housing suitable for job-site and outdoor use

How does the integrated LED light help in practical scenarios?

The inverter includes a 200-lumen LED work light with three brightness modes and a 120° adjustable head for task illumination. It frees up your hands for repairs, campsite setup, or roadside assistance and runs off the same attached Makita battery powering the AC and USB ports.

• 200 lumens with high/medium/low modes for adaptable lighting
• 120° adjustable head for directional illumination
• Useful for night work, camping, or emergency light source
• Integrated power button and mode cycle for quick operation

Who is this for? The Ecarke 200W Makita 18V Power Inverter suits tradespeople, outdoor enthusiasts, and homeowners who already own Makita 18V batteries and want a compact, no-fuss way to power small electronics off-grid. If you need a portable AC outlet, fast USB charging, and a built-in work light from your existing tool batteries, this unit delivers convenient, protected power without extra adapters. It is not a replacement for high-capacity inverters or permanent backup systems.
