Ryobi is launching a new 40V cordless power tool battery belt, OP40HBA, allowing users to pack greater electrical energy capacity off the tool.
Basically, this means longer runtime, and the weight is carried by your body.
The two battery ports can work with all Ryobi 40V batteries.
Additional features include a battery selector on the tool adapter, an LED indicator for showing the charge capacity status of the battery in use, adjustable shoulder strap, and a foldable design for compact storage. The shoulder straps are removable, in case you want to wear just the hip belt.
The Ryobi 40V belt power supply weighs 5 lbs (presumably without batteries).
The power supply should work with all Ryobi 40V handheld cordless power tools.
ETA: June 2023
The way I see it, there are two benefits for something like this. First, it keeps some weight off the tool, which might help reduce fatigue.
Second, maybe it’ll save you a long walk back to the charger or wherever you keep your fully charged batteries, although I’m not sure how much of a difference it will make.
The premise is that it gives you longer runtime with less interruptions.
Obviously there are some tools this probably shouldn’t be used with; it seems optimized for handheld tools, such as a cordless leaf blower. It seems like it will be very awkward to attach this to something like a cordless shop vacuum.
