WIRELESS POWER TRANSFER EXPERIMENT

Do you know anything that uses wireless power transfer near you? With this experiment kit, students learn how wireless power transfer works — and discover why electricity can pass even without wires or direct contact. Connect the transmission coil to its USB-powered oscillator, place one of the five included receiver coils nearby, and its LED lights up with no wires at all.

The learning doesn't stop at the bench: the same principle powers a whole range of craft projects. Following the included guide, students can build glowing lanterns from a decorated bottle, and go on to create snow globes, glitter hourglasses, glowing dolls, treasure hunt games and more — everyone from children to adults can enjoy it, with variety limited only by their ideas.

•     See electricity jump — LEDs light up across an air gap — a vivid, memorable demonstration of wireless power transfer.

•     5 receiver coils — Five receiver coils with LEDs are included, so multiple students or projects can run at once.

•     Simple USB power — The transmitter oscillator runs from a standard USB power adapter (maximum output 1 A or more).

•     Experiment + craft — Step-by-step lantern instructions included; extend to snow globes, hourglasses, dolls and games.

•     Real-world technology — Learn while experiencing advanced technology — the same idea behind everyday wireless charging.

•     All ages — Suitable for everyone from children to adults (children under 9 supervised by an adult).

•     Classroom demonstrations of wireless power transfer and electromagnetic induction concepts.

•     STEM craft projects — glowing lanterns, snow globes, glitter hourglasses, glowing dolls and stirrers.

•     Creative activities — treasure hunt games, astronomical observation sets, glowing model decorations.

•     Science clubs, fairs, open days and holiday programs for mixed-age groups.

•     Linking bench-top learning to everyday technology such as wireless charging.

1.   Attach the transmission coil to the oscillator first — never power the board without the coil attached, as the transmission section will generate heat.

2.   Plug the USB cable into a USB power adapter with a maximum output of 1 A or more.

3.   Place a receiver coil (with LED) on or near the transmission coil and watch the LED light — wirelessly.

4.   To make a lantern: unplug the power, glue the power-receiving LED coil inside a non-metal bottle lid, decorate the bottle with non-metal accessories, close the lid tightly, then place it on the transmission coil.

5.   Keep any metal objects at least 5 cm away from the transmission coil to avoid overheating.

6.   If the LED will not light, the protection circuit may have activated — unplug the power, wait a while, check that the coil is attached properly and no metal is nearby, then reconnect.

7.   Unplug the power when preparing crafts or when the kit is not in use, and keep the (non-waterproof) transmission board away from water.
