300 ml diffuser

Most 300 ml diffusers are powered by an AC adapter. Some models use a small battery only for a remote (commonly a CR2025) or include no onboard batteries at all.

A common safety feature is automatic shut-off when the water level is low (waterless auto‑off), which turns the unit off to prevent damage or overheating.

Many 300 ml diffusers offer multi‑color or color‑changing LED lights (for example, 7 ambient colors). Some provide adjustable white‑tone or brightness settings and dedicated sleep or circadian lighting modes.

Timer and mist modes vary by model. Common presets include 1H/3H/6H continuous mist options, while other listings offer 1‑, 4‑ and 8‑hour timers. Specific modes depend on the unit.

Common inclusions are an AC power adapter and, on some models, a remote control. A few listings also include sound options or an essential oil blend as part of the package.
