A sleek design engineered for reliable, everyday performance, the durable electric stapler can be powered by AC adapter or wire-free AA batteries for stapling of 2 to 20 sheets. Depending on setting, choose between an AC adapter for standard desktop use, or four AA batteries for on-the-go travel use (batteries not included). Motorized design delivers quiet operation while the extra wide paper lead-in allows for quick positioning, stapling at a 45-degree or 90-degree angle. The FastLoad™ push-button system makes reloading staples incredibly easy. Non-skid rubber base protects desktop surfaces and provides extra stability. For best results, use with Bostitch Premium Standard Staples
