Expand your RYOBI 40-Volt system with the 40-Volt Belt Power Supply. This belt power supply helps you achieve extended runtime on RYOBI 40-Volt handheld tools by having extra batteries right by your side, even when you're far from your house, garage or shed. Utilize power from the 2 active battery ports by plugging the 40-Volt adaptor into your 40-Volt handheld tool. The belt decreases fatigue by taking the weight of the batteries off the tool and features adjustable shoulder straps that offer additional support allowing you to work comfortably for longer tackling big jobs. This is especially beneficial when using a higher amp hour battery on tools, such as string trimmers, blowers, hedge trimmers and chainsaws. A convenient LED indicator on the adaptor shows remaining charge of the battery in use and the belt folds for compact storage when not in use. Best of all, it is part of the RYOBI 40-Volt System where any 40-Volt battery works with any 40-Volt product. This 40-Volt Belt Power Supply is backed by the RYOBI 3-Year Manufacturer's Warranty and includes (1) OP40HBA 40-Volt Belt Power Supply and Operator's Manual. Battery sold separately.
