Ryobi is one of the leading power tool manufacturers on the market. They have a great new system which makes buying Ryobi 18v power tools and batteries a real breeze. The system is called one+ and basically means that all of their 18v power tools run on the same batteries, which in turn means that the same charger can be used. This is a really great idea that really makes a lot of sense. You won’t need to buy different kinds of accessories for each of your power tools. This obviously saves the user quite a bit of money. Another benefit is that you will never need to carry a lot of equipment to the job site.
