This product is final sale. Grenco Science’s G Pen Pro is the most compact of all G Pen products. It’s equipped with a single-button system that powers and heats the device to one of three preset temperatures: 375°F (blue), 400°F (green) and 428°F (red) within 30 seconds. The device has a silicone mouthpiece and an outer casing made of a lightweight, durable aluminum, while its internal ceramic heating chamber holds a capacity of 0.25 g of dried flower cannabis. The battery of this compact vaporizer will yield 45 to 60 minutes of continuous use before needing to be charged, which takes two to three hours. The device automatically shuts off after five minutes to preserve the cannabis and battery. Included with the G Pen Pro are a cleaning brush, a micro-USB charger and a packing tool. It’s available only in black and comes with a one-year manufacturer’s warranty.
