Industry Background

Portable electronic aroma diffusers have become one of the fastest-growing wellness products in recent years. As people seek stress-relief and personal aromatherapy experiences in homes, offices, cars, and travel environments, compact and cordless diffusers are increasingly preferred. Behind this shift lies the essential contribution of lithium-ion battery technology, enabling portability, long-lasting performance, and ease of use.

Modern aroma diffusers rely on ultrasonic atomization modules, micro-pumps, microcontrollers, essential oil delivery systems, and ambient lighting effects. With consumers expecting consistent mist output, low noise, and elegant design, optimizing power efficiency becomes a key engineering challenge. Many high-end diffusers now adopt wireless designs, relying fully on rechargeable lithium batteries instead of traditional USB-only power modes.

Pain Points in Power System Design

Developers of high-performance aroma diffusers face multiple engineering challenges, including:

1. Very limited internal space for batteries and electronics
2. High instantaneous current required for ultrasonic atomization
3. Long operating cycles demanding stable discharge performance
4. Safety concerns when essential oils are present inside the device
5. User expectations for USB-C fast-charging compatibility

For these reasons, disposable batteries or low-quality lithium cells are unsuitable for modern design requirements.
