KUNLUN OP401 40-Volt Battery Lithium-Ion Charger for Ryobi 40V OP4050A OP4026 OP40601 OP4040 OP4030 OP4015 OP40201 Li-ion Battery with LED Indicator(40V Batteries Not Included)

What It Is

The KUNLUN OP401 is an aftermarket 40-volt lithium-ion charger designed to recharge Ryobi 40V batteries. It’s for use with Ryobi 40V cordless lawn mowers, trimmers, blowers, and other outdoor power equipment that uses the same battery platform.

Fitment & Compatibility

This charger is compatible with Ryobi 40V batteries: OP4050A, OP4026, OP40601, OP4040, OP4030, OP4015, and OP40201. It does not work with 18V, 36V, or 80V Ryobi batteries. Before buying, confirm your battery model number (printed on the battery label). It will not charge Ryobi 40V batteries from older or non-standard series (e.g., OP40401A, OP4030A). The charger uses a standard 120V AC household outlet—no adapter needed. It is not an OEM Ryobi part; it’s a third-party replacement.

Key Things to Know

• Charging speed: Typically slower than OEM Ryobi chargers—expect 2–4 hours for a 4Ah battery.
• LED indicator: Shows red (charging) and green (fully charged), but some users report the light stays green even if the battery isn’t fully charged.
• Build quality: Plastic housing feels less durable than OEM; avoid dropping or exposing to moisture.
• No battery included: This is the charger only—you must already own a compatible Ryobi 40V battery.
• Installation: Plug and play—no wiring or assembly required.

Should You Buy It

Buy this if you need a spare or backup charger for your Ryobi 40V batteries and don’t want to pay the OEM price (typically $35–$50). It’s also a decent budget option for light-duty users. Skip it if you need fast charging, maximum reliability, or plan to use it daily in a professional setting—the OEM Ryobi charger is more consistent and better built.
