Longzhuo Automatic Touchless Liquid Soap Dispenser (400ml) with Infrared Sensor and IPX5

If you want soap without the usual “everyone’s hands on the pump” moment, this Longzhuo automatic liquid soap dispenser leans hard into touchless hygiene. It uses an infrared sensor for hands-free dispensing and is aimed at kitchens, bathrooms and other busy spots where cross-contamination matters.

Quick overview

On paper, the big attractions are the touchless sensor, a 400ml tank with a visible window, and a rechargeable setup with USB‑C charging. The dispenser also offers 4 adjustable dispensing/foam settings, plus a battery indicator so you’re not caught out.

That said, it’s not a smart, app-connected unit and it depends on the sensor doing its job consistently in real-world lighting and hand distance. If you’re the sort of person who wants total “set and forget” perfection with zero learning curve, you may find it a bit more hands-on than expected.

The essentials (what it’s for)

This is a touchless liquid soap dispenser designed to help you dispense soap without pressing a button. The core use case is simple: you place your hands under the spout, the infrared sensor detects them, and liquid comes out.

A practical example: in a kitchen, you can rinse food prep hands quickly without hunting for the pump, and then you’re not leaving fingerprints on the dispenser after every use. In a shared bathroom, it also reduces the “who last touched it?” problem, which is exactly where touchless systems tend to be most appreciated.

Where it shines in day-to-day use

Several details make it feel built for everyday convenience rather than just looks.

• Touchless and hygienic by design: the infrared sensor approach is meant to reduce cross-contamination in higher-traffic areas.
• 400ml capacity with a visible window: the window helps you judge when refills are coming, so you’re less likely to discover it’s empty at the worst time.
• Drip-conscious dispensing: the unit is described as having an extended spout intended to help prevent drips and sticky residue.
• Rechargeable with USB‑C: you’re not limited to disposable batteries, and it’s designed for charging with USB‑C.

If you’ve ever had a manual dispenser that ends up messy around the nozzle, the extended spout idea is the kind of small feature that can matter more than you’d think.

Key points on power, settings and control

This model is set up to give you a bit of control without getting complicated. It features 4 adjustable foam/dispensing levels, so you can tune how much comes out depending on the soap and how you like it.

There’s also a battery indicator, which is useful because the dispenser’s performance is tied to power level. The brand claims a 90-day long-lasting battery and notes 600+ uses per charge, which—if your usage is similar—could mean fewer charging moments than you’d normally expect from touchless dispensers.

One limitation to keep in mind: the real-world number of uses per charge depends a lot on how often you dispense and which setting you use. If you run it at the highest level all day, the “long lasting” part will naturally vary.

Things worth checking before you buy

Before committing, it’s worth thinking about where it’ll live and how you’ll refill it.

• Wall mounting surface: the package includes a strong adhesive wall mount “no drill”, so the surface needs to be suitable for strong adhesion (smooth, clean areas usually matter most).
• Liquid type and thickness: it’s presented as compatible with any liquid, but foaming and flow can vary depending on how thick your soap is. If you use a particularly viscous or very low-foam liquid, your experience may differ from someone using a more typical foaming soap.
• Sensor behaviour: touchless units rely on detection. If you have strong overhead lighting or your hands hover too far from the sensor, you may find it needs a slightly consistent placement under the spout.

Pros and limits (honest buying perspective)

What you’ll probably like: - Touchless operation for better hygiene in shared spaces. - Large enough 400ml tank with a visible window. - USB‑C recharge with a claimed long battery life. - 4 dispensing levels so it’s not one-size-fits-all. - IPX5 waterproof rating suited to kitchen and bathroom environments.

Where it may feel less ideal: - If you want the most “set and forget” experience possible, you may need to adjust hand positioning for reliable activation. - It’s built around liquid soap dispensing, so if you mainly want a heavy sanitiser gel or an ultra-thick product, compatibility is “any liquid” on paper—but results can still vary in practice.

Should you buy it?

It makes sense to buy this Longzhuo touchless liquid soap dispenser if you’re shopping for a wall-mounted, rechargeable unit that reduces contact in kitchens, bathrooms or hotel-style high-traffic areas, and you want a decent 400ml capacity with adjustable dispensing levels.

You may want to skip it if you’re expecting a fully “smart” experience, or if you prefer super-simple manual control where sensor placement doesn’t matter at all. It’s a practical, mid-category choice for people who value hygiene and convenience, but it’s not the sort of product that eliminates every small real-world variable—like consistent hand distance.
