※ This product does not include a charger. This is a set to attach a cooling fan to the GFORCE RECORDBUSTER charger/discharger (made with a 3D printer). ※ Please be aware that there may be characteristic layer lines. ※ There may be some scratches due to shape confirmation and attachment confirmation after creation. ※ Contents are as shown in photo 5. It is attached to the main unit via a U-shaped part. It is detachable, so it doesn't take up much space when carrying. Air is drawn in from the top and exhausted through the gaps on the front, back, left, and right. It can be flipped up for battery replacement. ●【Fan Overview, per unit】 ・Power supply voltage: 5V ・Power supply specification: USB ・Current: 0.06A ・Rotation speed: 3500rpm ・Dimensions: 50mm x 50mm x 10mm ・Wiring length: Approximately 60cm (including USB plug, with some error) ※ It is designed to be powered from the charger itself.
