200W Power Inverter Compatible with Ryobi 18V Battery - Portable Power

In this review the Ecarke 200W power inverter is examined as a lightweight way to turn existing Ryobi 18V tool batteries into a small portable power station. It is aimed at users who already own Ryobi 18V lithium-ion packs and need a compact source of AC power and fast USB charging on the go; the single biggest reason to buy is convenience, since the inverter requires no extra adapter and delivers a 110V/200W AC outlet plus multiple USB ports from a tool battery. Battery not included, so this is a useful add-on rather than a standalone generator.

Key Features

• Ryobi 18V compatibility: Fits common Ryobi 18V lithium-ion packs so users can reuse existing batteries to power devices without buying a separate battery system.
• 200W AC outlet: Converts battery power to clean 110 V/200 W AC for laptops, cameras and small appliances suitable for job site or camping use.
• Dual USB-A and USB-C ports: Two 5 V/2.1 A USB-A ports plus a 5 V/3 A USB-C port provide up to 20 W of rapid charging for phones and tablets simultaneously.
• Built-in 200 lm LED work light: An integrated 3-mode spotlight with 120 degree adjustable head gives hands-free illumination for night work and roadside repairs.
• Thermal and electrical protection: Smart fan cooling and multi-layer safeguards help protect against over-heat, overload, short circuit and battery over-discharge for safer operation.

Who It's For

This inverter is best for DIYers, tradespeople, and campers who already own Ryobi 18V batteries and want a compact way to run small AC devices and charge USB gear without carrying a larger power station. It suits occasional backup power needs, short job site tasks, and overnight camping where 200 W is sufficient.

It is not for users who need long runtimes, high-power appliances, or a battery included in the kit; those seeking multi-hundred-watt continuous output or extended off-grid use should consider larger inverter-generator systems instead.
