Panasonic Multi Voltage 14.4v, 18v Cordless Blower SKIN - (EY37A1) The Panasonic EY37A1 cordless blower is part of the new multi voltage range, which is compatible with 18v and 14.4v batteries, old and new. This allows the user to tailor the weight, size, power and runtime of the tool to the task in hand. For example, an 18v battery will give you more power and a longer runtime at the cost of weight, and if you need to work in a tight space or overhead you can simply swap the battery for a lighter one!
