Overview
The SunAura heated hand warmer pad (model NYRN08/A) is a 5 V, USB-powered heating cushion built around a flexible graphene far-infrared film. As a heated hand warmer pad, it is a soft 40 × 27 cm pillow covered in milk fleece and cotton that heats the whole surface evenly in about three seconds. It runs from any USB power bank, laptop or adapter, offers three heat levels, and doubles as a hand warmer, an abdominal warming pad and a small heated cushion for a desk, sofa or car seat.
The design point that distinguishes it from a small rechargeable hand-warmer is the whole-area, point-free heating. Instead of two palm-sized hot pads, the graphene film spreads uniform warmth across the entire 40 × 27 cm surface, so both hands rest in a single warm zone, or the pad can lie across the lap or stomach. For brands and importers it is a versatile OEM product: colours (gray, black as standard, custom on request), shell, size and packaging are all adjustable, and we manufacture the element and assemble the pad at our Qingdao factory.
The product sits in the low-voltage heated-textile category, where buyers increasingly prefer light, USB-powered cushions over bulky mains heating pads. Because the pad draws only 5 V, it shares the power ecosystem of a phone and a power bank, which removes the need for a dedicated adapter and makes it an easy travel and desk companion. As the factory behind it, our role is to give brands a stable, well-tested element and a repeatable cushion build so that reorders match the approved sample exactly.
How Graphene Heating Works in the Pad
The heating core is a thin, flexible graphene far-infrared film powered at a safe 5 V. When the user selects a heat level, the film reaches comfortable warmth in roughly three seconds and radiates far-infrared energy in the 5–14 µm band that the body absorbs. Because the element is a planar film rather than a resistive wire, the entire 40 × 27 cm surface heats uniformly — there are no hot wires and no cold corners. That even coverage is what lets the pad work as a general warming cushion rather than a point hand-warmer.
The low 5 V voltage is what makes the pad comfortable against skin and safe to use in bed or on a lap. It removes the shock and overheating concerns of mains-voltage heating pads and lets the pad share the same USB power ecosystem as a phone. The milk-fleece outer adds a soft, touchable surface that holds the radiant warmth next to the body, while the cotton backing gives the cushion structure so it holds its shape on a desk or seat.

Design and Multi-Use Function
At 40 × 27 cm the pad is sized to cradle both hands or to rest across the lap or lower abdomen. The rectangular pillow form holds its shape on a desk, sofa arm or car seat, and the milk-fleece surface is soft enough to use directly against skin. The USB lead exits with a reinforced strain relief and connects to a small in-line controller with three levels and an indicator, so the user changes heat by feel without lifting the pad.
Because the whole surface heats uniformly, the pad adapts to different uses through a single product: hands tucked under or on top of it on a cold desk; laid across the stomach for abdominal warmth in the evening; used as a small heated seat pad on a hard chair or car seat; or carried in a bag for travel. That multi-use nature is its main retail advantage — it is priced and positioned as one pad that replaces several small warming gadgets.
How It Compares With Other Warmers
Against a rechargeable pebble-style hand warmer, this pad covers a much larger area and warms both hands at once, but it relies on a USB source rather than a built-in battery. Against a mains electric heating pad, it is far lighter, safe against skin, and portable enough to carry, but it does not reach the surface temperature of a 220 V pad — by design, because a personal comfort pad should stay at a body-friendly warmth. Against a microwaveable wheat pack, it holds a steady temperature for as long as the power bank lasts and offers three selectable levels instead of a single, fading warmth. The trade-off the buyer accepts is the USB cable; the benefit is even, adjustable, repeatable warmth in a soft cushion that does not need to be reheated in a microwave.
For a brand, that positioning makes the pad easy to merchandise as a desk and home comfort item rather than a medical pad. It is sold on comfort, portability and the multi-use story, which keeps the marketing clear and avoids medical-device claims.

Materials and Build Quality
The outer is a milk-fleece pile over a cotton backing, chosen for a soft, premium hand-feel and for a clean appearance in product photography. Inside, the graphene heating film is encapsulated and held flat within the cushion so it cannot fold onto itself or create a local hotspot, and the USB connection is strain-relieved where it exits the pad. At 5 V the surface runs to a comfortable, self-limiting range, and the three-level controller lets the user choose the output rather than running the element flat out.
Factory-side, the element is the same low-voltage graphene film used across our USB wearable range, so resistance tolerance and termination quality are consistent across the product family. Each finished pad is tested for continuity and heat function before packing. Because the product is a textile cushion, the OEM package includes care instructions and guidance for disconnecting the USB lead before cleaning, so end users can maintain it safely.
Our outgoing QC checks the element resistance against the approved sample, the three-level controller switching, the USB lead strain relief, the flat encapsulation of the film inside the cushion, and the finish of the milk-fleece and cotton shell. Pads that fail any check are reworked or removed before packing, so bulk stock matches the sample you approved. Spare elements and controllers are held for after-sales support under longer-term supply agreements.
Typical Applications and Use Cases
The hand warmer pad is used at a desk, on the sofa, in the car and while travelling. At a desk it keeps both hands warm through a cold morning or in an under-heated office; on the sofa it provides lap and hand warmth in the evening; in the car it slots onto the seat or rests on the lap for winter commutes; while travelling it runs from a power bank on trains and in waiting rooms. It is also popular as an abdominal warming pad for users who feel cold around the stomach, and as a comfort product in wellness and winter-gift ranges.
For older users and people with poor circulation in the hands, the pad removes the need to grip a small warmer and instead lets both hands rest on a warm surface. For office workers it replaces the desk-side hot water bottle, and for students it works in cold lecture halls. Because it is light and soft, it is also a comfortable lap pad for reading or working on a laptop, where the underside of the arms and legs otherwise get cold against a hard chair.
Retailers find it easy to sell because the multi-use story is concrete: one pad warms hands, lap and abdomen. It pairs naturally with the heated neck wrap and the heated vest as a coordinated winter comfort set, and it works as an impulse or gift purchase at the cooler price point.
Why Choose SunAura as Your Heated Hand Warmer Pad Manufacturer
SunAura Thermal has manufactured graphene and low-voltage heating textiles from our Qingdao factory since 2008. We supply this heated hand warmer pad to importers, home-textile brands and wellness retailers who want a consistent OEM product rather than a generic sourced item. 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 and product photography, and we scale from sample orders to container programmes.
Working directly with the factory means the element spec and cushion build are documented the same way on every reorder, so you do not receive a different product six months later. We keep tooling and element parameters on file and assign a contact who understands your channel, target retail price and packaging requirements. That continuity turns a one-off sample into a repeatable seasonal product line.
Safety and Compliance
At 5 V the pad runs at a safe low voltage with no mains connection, removing shock and over-voltage risks associated with 220 V heating pads. The three-level controller lets the user avoid the highest setting for prolonged wear, and the element is encapsulated flat within the cushion. For export we provide CE and RoHS documentation and test-report references; see the certifications and compliance page for our coverage. As with any heated textile, users should not fall asleep on the highest setting and should keep the USB power source dry and ventilated.

A: Any standard 5 V USB source: a power bank, laptop, USB adapter or car USB port. Runtime depends on the source capacity and the heat level selected.
How is this different from a small rechargeable hand warmer?
A: It heats a whole 40 × 27 cm surface uniformly rather than warming two small points, so both hands, the lap or the abdomen can be warmed at once.
Can I wash the pad?
A: Disconnect the USB lead and controller before cleaning. Care instructions, including any removable-element guidance, are supplied with the OEM manual; confirm the washing method on your order specification.
What colours and custom options are available for OEM?
A: Standard colours are gray and black. Custom colours, shell fabric, size, labels, hangtags and retail packaging are available for private-label and wholesale orders.
What is the MOQ and lead time?
A: Minimum order quantity and lead time are agreed per project on the quotation. Sample units are available for evaluation before a volume order.
Can it be used as a seat or abdominal pad?
A: Yes. Because the whole surface heats evenly, it works as a hand warmer, a lap or abdominal warming cushion and a small heated seat pad on a hard chair or car seat.
How long does it take to heat up?
A: The graphene film reaches comfortable warmth in about three seconds once powered, with no long preheat.
