The 4smarts 540466 100W Indoor 20V Grey power adapter is a compact indoor power accessory with a grey aluminium housing and passive cooling.

The adapter is lightweight (approximately 0.01 kg) and intended for stationary indoor use, offering a straightforward solution for sharing a USB-C charger between laptops and other devices.
Advantages
The adapter supports Power Delivery up to 100W, allowing faster charging when used with a compatible USB-C power source.
