Heated Vest — USB Graphene Heated Body Warmer (5 Zones)

Overview

The SunAura heated vest is a 5 V, USB-powered body warmer built around built-in graphene heating elements. As a heated vest, it combines a waterproof outer shell with a warm down fill and targeted heating zones across the waist, abdomen, shoulders, neck and chest. It warms up in about three seconds, offers three heat levels, and runs from any standard USB power bank carried in the inner pocket. The result is a light, packable garment that keeps the core warm on cold commutes, at outdoor work, at sports sidelines and in under-heated buildings.

What sets this vest apart from a generic battery vest is the graphene element: a thin, flexible planar film that spreads heat evenly across each zone rather than projecting warmth from a few wire points. The far-infrared output is associated with relief in the back, shoulder and lumbar areas, which is why the vest is popular with older users, outdoor workers and anyone who feels the cold in their torso. For brands and importers, it is a fully OEM-ready garment: heating zones, materials, colours and sizes are customizable, and we manufacture the element and assemble the vest at our Qingdao factory.

How Graphene Heating Works in the Vest

Each heated zone contains a flexible graphene far-infrared film powered at a safe 5 V. When the user selects a level, the film reaches operating warmth in roughly three seconds and radiates far-infrared energy in the 5–14 µm band that the body absorbs. Because the film is planar, the heat is spread evenly over the zone, so the shoulder, lumbar and chest areas warm uniformly instead of showing the hot-strip pattern typical of wire-based vests.

The 5 V architecture is deliberate. It keeps the vest safe against the body, allows it to run from a phone power bank that most customers already own, and avoids the bulky, proprietary battery packs that make traditional heated jackets uncomfortable. The down fill traps the radiant heat next to the body, and the waterproof shell blocks wind and light rain, so the garment works as both an outer layer on a mild day and an insulating mid-layer under a heavier coat in winter.

Zone-based heating also means the user is not forced to heat the whole garment at a fixed output. The three-level controller steps the power up or down, so a commuter can run a low level on a short walk and switch to a higher level when standing still at a bus stop or on a winter sidelines. Because the element warms in three seconds, there is no dead time waiting for the vest to come up to temperature — it is warm by the time the user has zipped up.

Key Specifications

Heating Zones, Sizes and Custom Options

The vest is configured with heating across the waist and abdomen, shoulders, neck and chest, so the core and the joints that stiffen in cold are all covered. Because the element is a flexible film, the number and position of zones can be adjusted for an OEM programme: a buyer may want more coverage on the back for lumbar relief, or a narrower chest zone for a slimmer fit. Sizes, shell fabric and fill weight are likewise adjustable, and the inner pocket is sized to hold a common power bank with the USB lead routed to the controller.

For private-label orders we also handle the label, hangtag, size grading, multilingual care label and packaging. We recommend confirming the target market climate when selecting fill weight and shell: a mild winter market may prefer a lighter vest, while a cold-climate buyer will want the fuller fill and the waterproof shell. The three-level controller lets the user dial output to the conditions rather than relying on a fixed heat output.

Design and Wearability

The vest is cut as a regular body-warmer shape: a front zip, armholes and stand collar, so it layers naturally over a shirt or under a shell. The heating zones are placed where the body loses the most core heat and where joints stiffen in cold — the upper back and shoulders, the lumbar and waist, the abdomen and the chest. Because the graphene films are thin and flexible, they do not create a bulky panel or a rigid board under the fabric, so the vest moves with the wearer and does not show a visible heating outline. The inner power-bank pocket sits at the lower side so the added weight is balanced against the body rather than bouncing.

For e-commerce and retail, the clean vest silhouette photographs well on a model or flat-lay, and the three-level controller is easy to demonstrate in a short clip: connect the power bank, press the switch, and the zones warm in seconds. Buyers who sell heated apparel value a product that does not require a proprietary battery, because that removes a common after-sales complaint and a separate SKU to stock.

Key Features and Benefits

• 3-second warm-up — the graphene zones reach comfort heat almost immediately after the power bank is connected.
• Safe 5 V USB power — runs from a standard power bank; no proprietary battery pack to buy or replace.
• Five heated zones — waist, abdomen, shoulders, neck and chest cover the core and the joints that stiffen in cold.
• Waterproof shell + down fill — blocks wind and light rain while trapping radiant warmth next to the body.
• Three heat levels — match output to the weather and activity.
• Uniform far-infrared heat — planar graphene film avoids hot spots and cold gaps.
• Light and packable — folds small enough for a glove box, backpack or office drawer.
• Fully OEM customizable — zones, materials, colours, sizes and packaging adjustable for wholesale orders.

Materials and Build Quality

The outer shell is a waterproof fabric selected to shed light rain and block wind while remaining light enough to wear indoors. The down fill provides the insulation layer that holds the element’s radiant heat close to the body; without that layer, the heat would dissipate quickly. The graphene films are encapsulated and routed through reinforced channels so they do not shift or chafe during movement, and the USB connection exits through a strain-relief point to the in-line three-level controller. The power bank lives in an inner pocket that keeps it against the body and out of the way.

From a manufacturing standpoint, the vest uses the same family of low-voltage graphene elements we build into our neck and hand warmers, so resistance tolerance and termination quality are consistent across the wearable range. Each finished vest is tested for continuity across every zone and for controller function before packing. Because it is a garment, the OEM package includes washing and care guidance, including how to disconnect the power bank before cleaning, so the product is safe to merchandise as a washable heated apparel item.

Our outgoing QC checks each zone’s element resistance against the approved sample, the three-level controller switching, the USB lead strain relief, the inner power-bank pocket, and the shell and fill finish. Vests that fail any check are reworked or removed before packing, so bulk stock matches the approved sample. Spare elements, controllers and power-bank pockets are held for after-sales support under longer-term supply agreements.

Typical Applications and Use Cases

The heated vest is worn in three broad ways. As an outer layer on mild but cold days, it replaces a thicker coat and gives the user hands-free warmth. As a mid-layer under a waterproof shell, it adds core heat for winter walking, cycling, fishing, spectating at sports, and outdoor work. As an indoor comfort garment, it helps office workers, older people and anyone who feels the cold stay warm in poorly heated rooms without raising the thermostat for the whole building.

Commercial buyers also use it as a staff comfort item for cold workplaces, as a promotional winter gift, and as a product in outdoor, workwear and health-and-wellness ranges. The fact that it runs from a phone power bank makes it easy to sell: customers already understand the power ecosystem, and the three-level function is simple to demonstrate in-store or in product video.

Why Choose SunAura as Your Heated Vest Manufacturer

SunAura Thermal has manufactured graphene and low-voltage heating garments and textiles from our Qingdao factory since 2008. We supply this heated vest to apparel brands, outdoor retailers and importers who want a private-label OEM product with a documented element spec, rather than a generic sourced garment. Because we make the graphene film in-house, we control heating performance, safety margins and lead time, and we offer factory pricing for wholesale and private-label orders. Our quality system is ISO 9001:2015 certified, and products are built to CE and RoHS requirements for export. We support buyers with datasheets, multilingual manuals, product photography and size-grade information, and we scale from sample orders to container programmes.

The practical benefit of factory-direct supply is consistency: the element parameters and build are kept on file, so a reorder six months later matches the approved sample. We work from your target retail price and recommended retail positioning to select shell, fill and zone configuration, and we handle the documentation importers need at customs. That continuity is what turns a sample into a repeatable seasonal line.

Safety and Compliance

At 5 V the vest runs at a safe low voltage with no mains connection, which removes shock and over-voltage risks associated with 220 V heated apparel. The three-level controller lets the user avoid the highest setting for prolonged wear, and the elements are encapsulated within the garment channels. For export we provide CE and RoHS documentation and test-report references; see the certifications and compliance page for coverage. As with any heated apparel, users should disconnect the power bank before cleaning, avoid sleeping in the vest on a high setting, and keep the power bank ventilated and dry.
