Mini S686 Shell Throwing Soft Bullet Launcher Toy Gun Airsoft Foam Bullet Blaster CS Outdoor Weapon Children Pistol Gift for Kid

The child is happy. Works on batteries, it's more fun with them, but it also ejects cartridges without them.

How do I charge it? No instructions, no description, just a piece of metal.

Thank you very much son very satisfied
