ASAKUKI Essential Oil Diffuser 700 ml

When you want a diffuser running through a long evening without frequent refills, a larger tank and hands-free controls can make the routine easier. The ASAKUKI Essential Oil Diffuser holds 700 ml and is designed to work with the Tuya Smart app, Alexa, and Google Home.

Set a schedule from your phone, or use the buttons on the unit for a timed run. The tradeoff is that app setup requires a 2.4 GHz Wi-Fi network.

Where it shines

The main appeal is less interruption: the diffuser can run for up to 20 hours, according to the product details, so you can start it before settling in and avoid topping up a smaller tank as often. That runtime is a maximum, not a guarantee for every setting or use pattern.

Voice control can be handy when your hands are busy cooking or when you are already in bed. For example, you could ask a connected voice assistant to operate the diffuser rather than reaching for the unit. If you prefer a simpler, button-only diffuser, this one may involve more setup than you need, if you prioritize scheduling and voice access, the smart controls are the point.

It’s a great fit if you want app-based routines, selectable light, and a larger water capacity in one diffuser. The mist and light work independently, so you can keep the mist on while turning the LEDs off. That is useful when you want fragrance without a glowing light at night.

Key points

You can set customized on/off schedules in the Tuya Smart app. For a quick manual run, the diffuser also has physical 1-, 3-, and 6-hour timer options. It supports Alexa and Google Home after connecting through the app, but setup is limited to 2.4 GHz Wi-Fi. Homes using only another Wi-Fi band may not be able to use the connected features as described.

The built-in LED offers seven colors, which you can cycle through or set individually, the app also provides a nightlight mode. An automatic shutoff turns the diffuser off when the water runs out. On the spec sheet, the combination of app schedules, voice commands, and manual timers gives you more ways to control it than a basic diffuser, but it also makes the Wi-Fi requirement worth factoring into your choice.

How to take care of it

The wide-opening tank is intended to make filling and cleaning easier. The product instructions recommend cleaning it every seven days with a soft brush or cloth. That is a recurring task to keep in mind, even with the larger capacity: fewer refills do not mean no routine maintenance. The automatic shutoff helps when the water is depleted, but it is not a substitute for cleaning the tank.

Should you buy it?

Choose this ASAKUKI if you expect to use schedules or voice control and want a 700 ml tank that can run for up to 20 hours. The independent light and mist controls are a useful extra if you like LED colors but sometimes want a dark room. It may not suit you if you want a completely straightforward, non-connected diffuser, or if your Wi-Fi setup does not support 2.4 GHz. The product details do not specify room coverage or mist output, so base your decision on its capacity and controls rather than assuming it will humidify a particular space.
