LZUMWS is a consumer-electronics and computer-accessories brand associated with HangZhou YaMao Information Technology Co., Ltd., a company based in Hangzhou, Zhejiang, China. Public trademark records indicate that the brand focuses primarily on power supplies, chargers, batteries, adapters, and computer peripherals.

The brand does not appear to have the extensive public corporate history or documentation of major electronics manufacturers such as Lenovo, Dell, Anker, or UGREEN. Consequently, some details about its history, manufacturing operations, ownership structure, and product strategy cannot be independently verified from authoritative public sources.

The U.S. trademark registration specifically covers batteries, battery chargers, cell-phone chargers, computer memory devices, computer peripherals, plug adapters, and power adapters for computers.

The brand is registered to HangZhou YaMao Information Technology Co., Ltd. Available trademark records identify the company as the original applicant and registrant, placing it in Zhejiang Province, China.

A Singapore trademark publication provides additional evidence regarding the company’s address, listing:

Room 614, Building 3, Wanguanghui Business Center, Gongshu District, Hangzhou City, Zhejiang Province 310000, China.

This same Singapore filing was made for Class 9 products and included a considerably broader catalog of electronics than the later U.S. registration.

Publicly documented information about LZUMWS begins appearing in trademark records in the early 2020s.

Timeline

• July 14, 2022 — LZUMWS trademark application recorded in Singapore. 1
• August 22, 2023 — U.S. trademark record lists first use in commerce.
• September 6, 2023 — U.S. LZUMWS trademark application filed.

The U.S. record states that LZUMWS had a claimed first use in commerce of August 22, 2023.

LZUMWS appears to be particularly associated with replacement power adapters for laptops and other electronic devices. Examples found in online marketplaces include:

• Laptop AC adapters
• USB-C laptop chargers
• Lenovo-compatible chargers
• Dell-compatible chargers
• HP-compatible adapters
• ASUS-compatible adapters
• Samsung-compatible laptop adapters
• Monitor power adapters
• 45 W, 65 W, 90 W, 135 W and 150 W-class adapters
• Batteries and battery chargers
• Plug adapters
• Computer peripherals

For example, one documented LZUMWS product is a 65 W USB-C adapter for Lenovo ThinkPad/Yoga computers, while other listings cover Dell, Samsung, HP and ASUS-compatible systems. The brand’s product range therefore appears to concentrate on replacement and compatibility-oriented accessories, rather than complete computers or smartphones.

LZUMWS appears to occupy the budget-to-midrange replacement-accessory segment of the electronics market. Its products are commonly marketed according to the device they are compatible with—for example, a particular Lenovo, Dell, HP, ASUS or Samsung laptop—rather than as part of a proprietary hardware ecosystem.

This positioning is significant because LZUMWS is generally encountered when consumers search for a replacement charger or adapter for an existing device, rather than when purchasing a new computer. Online marketplace listings also show LZUMWS products being sold in Singapore and other international markets.

The LZUMWS word mark has a distinctive stylized design. According to the U.S. trademark description, the letters “u,” “m,” and “w” are incomplete and connected to one another. The registration does not claim a particular color as part of the mark. 2

The brand name itself is somewhat unusual and does not appear to be an English-language word. Public trademark records do not provide an official explanation of what the letters “LZUMWS” stand for, so interpretations of the name should be treated as speculation.

Individual LZUMWS products may carry references to standards such as CE, FCC and RoHS, depending on the particular product. For example, documentation for an LZUMWS 150 W laptop adapter describes protections including over-current, over-voltage, over-power and short-circuit protection and states that the adapter is designed for 100–240 V input. 3

It is important to distinguish product-level certification or compliance claims from certification of the entire LZUMWS brand. A CE/FCC/RoHS reference on one product should not automatically be interpreted as meaning every LZUMWS product has undergone the same testing.

LZUMWS sells products designed to be compatible with equipment made by larger manufacturers such as Lenovo, Dell, HP, ASUS and Samsung. The available listings describe these products as replacement or compatible adapters.

There is no evidence in the sources reviewed that LZUMWS is owned by, or is an official subsidiary of, these companies. Thus, a product described as an “LZUMWS charger for Lenovo” should generally be understood as a third-party compatible/replacement accessory, rather than a Lenovo-manufactured charger.

LZUMWS has a relatively visible presence through online marketplaces rather than through a large publicly documented retail-store network. Search results show products under the LZUMWS name on marketplaces including TikTok Shop and Amazon-related listings.

This distribution model is consistent with many smaller electronics-accessory brands that sell internationally through e-commerce platforms.

Well-supported Information

• LZUMWS is a registered trademark.
• The trademark owner is HangZhou YaMao Information Technology Co., Ltd.
• The company is associated with Hangzhou, Zhejiang, China.
• The brand’s principal field is electrical and computer accessories.
• Laptop chargers and power adapters are an important part of its product range.
• LZUMWS has trademark registrations/applications in multiple jurisdictions.
• The U.S. trademark was registered in 2024.

Information Difficult to Verify

There is comparatively little reliable public information about:

• The company’s founding date
• Number of employees
• Annual revenue
• Manufacturing facilities
• Whether products are manufactured directly by YaMao or by third-party factories
• Detailed corporate ownership
• Global market share
• Official headquarters website
• Long-term product-development strategy
• Independent laboratory testing across the entire product range

Therefore, it would be misleading to present LZUMWS as a large established electronics manufacturer without additional evidence.

LZUMWS can best be described as a China-based electronics-accessory brand focused heavily on power products and replacement computer accessories. Its strongest identifiable category is laptop power equipment—particularly AC adapters and USB-C chargers for computers from other manufacturers.

The brand appears to have developed an international e-commerce presence, with products aimed at consumers looking for relatively inexpensive replacements for original equipment chargers and accessories. Its trademark history indicates that the brand was formally established in the early 2020s, with U.S. registration following in 2024.

It is not currently comparable in scale or public corporate profile to major electronics brands such as Lenovo, Dell, Anker or UGREEN. Rather, based on the available evidence, LZUMWS is better categorized as a smaller specialist/third-party electronics-accessory brand.
