Lost or broke your Ryobi 40V tool charger? Don't sweat it – this Powilling OP401 is a perfect and affordable replacement. It's compatible with a ton of Ryobi 40V lithium-ion batteries, like the OP4060, OP4050, OP4040, OP4030, OP4020, OP4026, and OP4015 models (basically, if it's a Ryobi 40V battery, it should work). This is a fast charger with a 2.0A output, which means it can top up most batteries in around 3 hours or less – way quicker than some older, slower chargers. It has a compact, wall-mountable design, so you can screw it right to your workshop wall to save bench space, or just use it on a tabletop. The charger has clear indicator lights to show you the battery status (charging, charged, error), and it even runs a diagnostic check with every charge to help optimize your battery's life and performance. It operates in temps from 32°F to 104°F and is RoHS and CE certified for safety. They've tested it with both original and third-party batteries, but if for any crazy reason it doesn't work with your specific battery, they offer a 12-month return service. Super handy to have a spare charger around, or just as a direct replacement to get your tools back in action fast.
