Products Description
①300ml Tank - Small Enough to Carry, Large Enough to Work
This portable ultrasonic glasses cleaner is equipped with a 300ml stainless steel tank, which can easily hold a full pair of regular eyeglasses. Unlike those tiny impractical gadgets, it is a practical ultrasonic cleaner designed mainly for easy carrying. Its inner space fits prescription glasses, reading glasses, most sunglasses and small daily jewelry perfectly.This ultrasonic cleaner is really small so you can take it with you.
②True Portability, Not Just "Compact"
Many so-called compact cleaners still weigh enough that they never leave the counter. The SE-931 is designed differently - as a mini ultrasonic glasses cleaner that actually travels. The reduced tank volume cuts weight meaningfully. The overall envelope fits readily in luggage compartments, desk drawers, and shelves that cannot accommodate larger units. For e-commerce sellers targeting travel-accessory categories, this dimensional profile opens placements bigger cleaners cannot reach.
③Simplified Controls for User-Friendly Operation
The SE-931 uses straightforward controls - power on, select cycle, start. No complex menus. This accessibility matters for end consumers using it at home (who want something that works without manual reading), and for retail staff in high-turnover environments. The small ultrasonic eyeglass cleaner delivers professional results through an interface anyone can operate in seconds.
④53KHz High-Frequency Performance in a Smaller Package
Cutting down tank size never compromises actual cleaning performance. This ultrasonic cleaning machine for glasses operates at 53KHz, which is higher than the common 45KHz frequency used in most regular household ultrasonic cleaners.Higher working frequency generates more delicate and dense cavitation bubbles. These tiny bubbles can easily get into narrow gaps of eyeglass hinges, the bottom of nose pads and edge slits of lenses. Meanwhile, it brings far less physical impact, so it will never harm fragile anti-reflective lens coatings.Its built-in transducer power is precisely adjusted to match the 300ml water capacity. This design makes full use of every bit of output power, avoiding excessive cleaning strength and ensuring proper working effect all the way.
⑤Durable Construction Despite Smaller Size
Portability sometimes signals fragility in consumer electronics. Not here. The tank is 304 stainless steel - identical grade to our commercial units. The body is built with high-strength impact-resistant ABS engineering plastic, perfectly suited for everyday use. This travel ultrasonic cleaner stands up well to frequent packing and unpacking. It works reliably for business trips, outdoor camping, and regular commutes between home and workplace.

As a practical eyeglass cleaning machine, the SE-931 fits perfectly into various gift scenarios. It works great for Father's Day gifts, holiday presents, corporate giveaways and customized gift sets. It also sells well on mainstream e-commerce platforms, where its reasonable price and compact package size effectively boost sales performance. The portable angle creates stronger gift rationale than stationary appliances. A bulk order of SE-931 units for Q4 gift season should be placed 8–10 weeks ahead to ensure delivery.
4. Optical Store Entry-Level Offering:
Independent opticians and smaller optical shops can stock the SE-931 as a take-home retail product - selling a cleaner alongside prescription services. Lower retail price compared to 600ml+ units makes it an easier impulse purchase.
5. Jewelry & Watch Quick Cleaning:
Despite 300ml capacity, the tank cleans individual rings, earrings, watches, and small pendants effectively. Jewelry kiosks and watch band retailers use this format for point-of-service cleaning demonstrations that drive attachment sales.
OEM / ODM Service
The SE-931 platform supports the same breadth of OEM and ODM customization as larger models, tailored for buyers in portable-personal-care, travel-accessory, and gift-retail channels. Private-label versions are particularly popular with airline catalog retailers and hotel amenity suppliers.
OEM Branding Options:
Logo placement: screen print, laser engraving, or branded label on housing
Custom retail packaging - box design, color scheme, multilingual text
Travel pouch or carrying case inclusion with branded exterior
User guide localization (major European, Asian, Middle Eastern languages)
Housing color variations (MOQ-dependent)
ODM Development Options:
Form-factor modifications within SE-931 platform constraints
Custom accessory bundle configurations
Firmware adjustments for timer defaults and indicator behaviors
Given target channels - especially gift and travel retail - allow at least 4–5 weeks lead time for custom-packaging orders. Standard logo-only orders turn faster.
FAQ
Q: Is the 300ml tank big enough for my glasses?
A: Absolutely enough for one pair of regular prescription glasses, reading glasses or common sunglasses. The inner space is 300ml. It is big enough for one pair of glasses.If your glasses have big frames or you want to clean many things at the same time,you can choose our 600ml SE-960/SE-960A or 650ml SE-962 ultrasonic cleaner models instead.
Q: How does cleaning quality compare to larger models?
The SE-931 operates at 53KHz - a higher frequency than the 45KHz common in household ultrasonic cleaners. The higher frequency produces finer cavitation bubbles that clean more thoroughly in hinge crevices and lens grooves, while transmitting less mechanical shock to AR (anti-reflective) coatings. Difference from larger models is capacity, not cleaning quality - the SE-931 cleans one pair as thoroughly as a 650ml unit, it simply cannot hold as many items or accommodate as-large frames.
Q: Can I use this for cleaning jewelry?
A: Yes you can use this for cleaning jewelry. This works well for items like rings, earrings, pendants, watches and chains. They all get clean well. If you have bigger pieces of jewelry or you want to clean a lot of things at the same time you should get a bigger model of this jewelry cleaner. That way you can clean jewelry, at once.
Q: Does it come with a travel case?
A: Base config includes unit, adapter, and basket. Branded travel pouches can be added as custom OEM options - discuss pricing and MOQ with our sales team.
Q: What is your MOQ for the SE-931?
A: Flexible depending on customization level. Stock-color units with factory packaging have lower minimums than custom-branded orders. Contact us - we work with new buyers on manageable initial sizes.
Q: Are you a factory or trading company?
A: Factory direct. Sonerc established 1999, manufactures through fully integrated in-house production. Foreign trade subsidiary handles international orders - no middlemen.
Q: What certifications does the SE-931 hold?
A: CE, LVD, and RoHS certification for EU, North American, and environmentally regulated markets. Documentation provided with shipments for customs clearance support.
Q: Is it safe to pack in checked luggage?
A: Yes. No prohibited materials inside. Empty tank before packing; wrap in clothing or pouch to prevent scratches. Stainless steel and ABS withstand normal baggage handling.
