COOLWAVE Cooling Vest: 5V Pump, TPU Bag & MOQ 10

For buyers evaluating a water-circulation cooling vest, the practical questions are specific: what the pump is rated for, what materials are listed, how long cooling is stated to last, and whether the order terms fit a pilot or production purchase. This FAQ brings those details together for the COOLWAVE Water-Circulation Cooling Vest associated with Shokunin, while distinguishing listed specifications from items that still require confirmation.

At a glance: specifications and purchasing terms

The product specification lists a 5V, 150mA maximum pump, a stated maximum flow range of 320–370 ml/min, a cooling duration of 3–4 hours, and a net weight within 2 kg. The product materials listed include a TPU water bag, polypropylene cap, sand rubber cooling tube, and 600D polyester shoulder strap. Supplier capability information lists ODM production, a 10-unit MOQ, a 7–14 day lead time, a 6-month warranty for the water-cooled vest, and monthly production capacity of 3,000 units.

Technical FAQ

What pump specification is listed for the COOLWAVE vest?

The product specification lists pump output as 5V and 150mA maximum. It also lists a maximum flow rate of 320–370 ml/min. These values provide a useful starting point for technical screening, but they do not by themselves define the pump’s operating conditions. The supplied information does not state a test setup, tubing length, water level, pressure head, or whether the flow figure was measured under a particular configuration. Buyers comparing samples or preparing an internal acceptance check should request the applicable measurement conditions rather than treating the listed range as a universal measured result.

Is the COOLWAVE vest a power-bank cooling vest?

The listed pump rating is 5V, but the available product specification does not identify a specific power bank, connector, battery capacity, or operating-time result. A 5V rating alone is not confirmation of compatibility with every power bank. For a power-bank cooling vest application, confirm the connection type, required output, operating instructions, and whether the power source is included or supplied separately. The product contents listed for the professional model are one water-cooled vest backpack and two ice packs; a power bank is not included in that contents list.

How long is the stated cooling duration?

The stated cooling duration is 3–4 hours. The product information does not provide the ambient temperature, workload, clothing layers, test method, or definition of the cooling-duration endpoint. Treat this as a listed product specification, not a guaranteed runtime under every work condition. For a long-lasting cooling vest requirement or a planned work period longer than the stated duration, buyers should evaluate a sample under their intended conditions and ask how the stated duration is measured. This is particularly relevant when planning use across a full shift or during prolonged outdoor work.

What does the 320–370 ml/min flow figure tell a buyer?

The figure describes the listed water-flow range for the pump, not a measured body-temperature reduction or a standalone measure of cooling effectiveness. It can help a technical buyer specify what needs to be checked in a sample, alongside the 5V, 150mA maximum pump rating. The supplied data does not include a standardized thermal-performance test or conditions that would support a direct comparison with another cooling vest. A fair sample review should therefore record the actual setup used and avoid comparing flow figures unless the measurement conditions are comparable.

Which materials are identified in the product information?

The product specification identifies the water bag as TPU, the water bag cap as polypropylene, the cooling tube as black sand rubber, and the shoulder strap as 600D polyester. It also lists PEVA as the product material. The supplied information does not map PEVA to a specific component or provide a complete bill of materials. Buyers with material-specific requirements should request a component-level material declaration and confirm which parts it covers. The available material list does not establish leakage resistance, washability, chemical resistance, or a service life, so those properties should not be assumed from the material names alone.

What is the listed net weight?

The listed weight is within 2 kg. The specification does not clarify whether this figure includes the two ice packs, water, a power source, or other accessories. The distinction matters when assessing a lightweight cooling vest for mobile work or comparing the carried load of complete configurations. Ask the supplier to confirm the weighing condition and request a sample weight using the accessories and operating setup intended for the project.

Application fit: where should buyers assess it?

The supplied application information associates COOLWAVE water-circulation cooling vests with construction work, outdoor work, metal sheet factories, street vendors, food stall operators, and traffic controllers. The scenario record describes high-temperature working conditions and personal heat-stress relief as the use context. These are application references, not evidence that the vest is suitable for every job, climate, uniform, or safety protocol in those sectors.

For a construction crew, metal-roof or metal-sheet work area, street-vending operation, or outdoor assignment with prolonged sun exposure, the procurement question is whether the listed configuration fits the actual task. Check wearability with the required work clothing, water and ice-pack handling, movement needs, and the expected operating period. The supplied corpus does not provide a validated heatstroke-prevention outcome, skin-temperature reduction, or standardized field-test result. A cooling vest should therefore be assessed as one item within the organization’s heat-risk controls, not treated as a substitute for a complete safety plan.

For buyers searching for an ice water circulation cooling vest, rapid cooling work vest, portable cooling vest, or professional cooling clothing, the terms should be translated into testable requirements. For example, define the desired wear duration, carried weight, pump electrical requirements, material documentation, and operating conditions. “High-efficiency” and “long-duration” are not quantified in the supplied product data beyond the listed flow range, weight, and 3–4 hour duration. The available evidence does not establish sweat-proof performance, a specific heatstroke-prevention result, or suitability for every extreme-heat environment.

Procurement FAQ

What is the minimum order quantity?

The capability information lists an MOQ of 10 units. This can be used as the initial planning figure for a small pilot or sourcing evaluation, but the supplied information does not say whether the MOQ changes by color, model, packaging, or ODM scope. Confirm the exact SKU and commercial configuration covered by the 10-unit minimum before preparing a purchase order.

Are ODM services available, and does that mean the vest can be customized?

The supplier capability record lists the production mode as ODM. However, the same record lists “customization” as “NO.” These entries do not establish that a buyer can change the product design, materials, branding, packaging, or specifications. Treat ODM as a listed service category and ask the supplier to define its actual scope in writing. Do not assume that a requested modification is available solely because ODM is listed.

What lead time is stated?

The listed lead time is 7–14 days. The capability information does not define when the clock starts, whether the period is for samples or production orders, or how it changes with order configuration. Buyers should confirm the start point, order quantity, approval requirements, and delivery milestone associated with this estimate before scheduling a deployment.

What warranty is listed?

The capability record lists a 6-month warranty for the water-cooled vest. It does not provide the warranty’s start date, covered components, exclusions, claim process, or remedy. Procurement teams should request the written warranty terms and clarify how pump or water-circulation issues are handled. The listed duration should not be interpreted as a complete warranty policy without those details.

Is monthly production capacity confirmed at 3,000 units?

The supplier capability record lists monthly capacity of 3,000 units. A separate company background record lists annual output of 10,000 units for the company as a whole. These figures use different scopes and periods and are not reconciled in the supplied information; they should not be combined or treated as interchangeable. Ask the supplier to define whether 3,000 units per month refers to installed, practical, or currently available capacity for this vest, and confirm the volume and schedule relevant to the order.

A practical evaluation checklist

Before selecting this industrial cooling vest for a crew, distributor program, or trial order, buyers can use the following checklist to turn the published details into verifiable purchasing requirements:

1. Confirm the exact configuration. Record the product name and model, color if relevant, included vest backpack, and two listed ice packs.
2. Validate electrical fit. Request the pump connection and operating instructions, confirm the 5V and 150mA maximum rating, and check any intended power source rather than inferring compatibility.
3. Define the sample test. Record how flow is checked against the listed 320–370 ml/min maximum range and define the conditions for evaluating the stated 3–4 hour duration.
4. Clarify what is weighed. Confirm whether the “within 2 kg” listing includes water, ice packs, or other accessories.
5. Request material details. Confirm the component mapping for TPU, polypropylene, sand rubber, 600D polyester, and PEVA, together with relevant care instructions.
6. Put commercial terms in writing. Confirm the 10-unit MOQ, 7–14 day lead-time basis, ODM scope, and the written terms of the 6-month warranty.
7. Check supply planning. Ask how the listed 3,000-unit monthly capacity is defined and allocated, especially if the project may require repeat orders.

How to interpret the specifications

The COOLWAVE specification set provides concrete screening points: pump voltage and current, a listed maximum flow range, stated cooling duration, weight limit, named materials, and several procurement terms. It does not include independent thermal testing, a complete pump test protocol, a confirmed power-bank configuration, or detailed manufacturing records. That boundary matters for procurement: published specifications help define what to request and test, but they do not replace sample validation or written commercial confirmation.

For the Shokunin COOLWAVE Water-Circulation Cooling Vest, the most defensible evaluation is therefore a configuration-specific review. Check the actual sample against the work scenario, obtain written confirmation for the order terms, and distinguish listed supplier information from results demonstrated under the buyer’s own conditions. This approach is relevant whether the search begins with “Dual Cooling Water Cooling Vest,” “industrial cooling vest,” or a specific need such as a portable cooling vest for outdoor work: the product’s suitability depends on the defined application and verified requirements, not on a keyword label alone.
