Edon 18v original spray gun

• Cordless & rechargeable (18 V battery): Gives you freedom of movement — no cords or power sockets needed, handy for outdoor jobs or remote areas. 
• Metallic paint tank (around 750 ml): The version you described reportedly includes a metallic (metal) paint container of about 750 ml capacity — decent volume for mid-sized jobs without frequent refills.
• Suitable for different coatings: It is described as usable with oil-based or water-based paints/varnishes — useful for wood, metal, fences, walls, furniture, etc. 
• Compact and portable design: Because it's battery-powered and cordless, it’s easier to carry and manage than a traditional air compressor-driven spray gunn.
• Easy to handle / user-friendly: The design targets convenience: simpler operation vs heavy-duty pneumatic gunns, likely easier cleaning and maintenance. 
• Versatile application: Good for home use (furniture, fences, small walls), light renovation, outdoor wooden fences, staining timber, varnishing and similar smaller-to-medium scale tasks.
