When it comes to heated vests, there are two popular options available: 7.4V and 5V battery heated vest. While many assume that 7.4V is always superior to 5V, both options have their own advantages and disadvantages. BOWINS Garment is the leading heated clothes manufacturer and supplier, in this article, we’ll delve into the differences between the two and help you make an informed decision.
1. What Is 5V vs 7.4V Heated Vest?
Heated vests often have two voltage choices: 5V and 7.4V, referring to the power supply they use. These vests are designed to provide warmth in cold environments by utilizing battery-powered heating elements.
1.1 What Is A 5V Heated Vest
- Powered by USB connections or lower voltage batteries.
- Considered safer due to the lower risk of electrical shock.
- Suitable for casual use or activities where intense heat is unnecessary.
- Ideal for providing gentle warmth during everyday activities or moderate cold conditions. They are often used indoors or for mild outdoor activities.
1.2 What Is A 7.4V Heated Vest
- Typically powered by lithium-ion batteries with a higher voltage.
- Generates more heat compared to 5V vests, offering enhanced warmth in colder conditions.
- Preferred for outdoor activities in extremely cold weather or situations requiring intense heat.
- Well-suited for winter sports, outdoor work in frigid temperatures, or instances where intense warmth is necessary.
The 5V option is generally safer and suitable for everyday use or activities where moderate heat suffices. Conversely, the 7.4V vest produces more heat, making it preferable for colder environments or demanding outdoor activities.
Battery life and heating duration may vary between the two options. Higher voltage vests consume more power, resulting in shorter battery life compared to lower voltage vests. If extended heating duration is important to you, consider battery capacity and the availability of spare batteries or charging options.
2. How Does Heated Vest Work?
A heated vest operates by utilizing a battery pack and heating elements to generate warmth. Here’s a breakdown of how a typical heated vest works:
2.1 Battery Pack
The heated vest is designed with a pocket or compartment to hold a battery pack. This battery pack is rechargeable and provides the power needed to operate the heating elements. The battery pack can usually be easily connected or detached from the vest.
2.2 Heating Elements
The heated vest contains heating elements, often made of carbon fiber, which are strategically positioned within the vest’s fabric. These heating elements generate heat when electric current flows through them. The number and placement of the heating elements may vary depending on the vest’s design, but they are typically located in areas such as the chest and back.
2.3 Powering the Heating Elements
When the battery pack is connected to the vest, the internal wiring of the vest carries the electrical current from the battery pack to the heating elements. The heating elements then convert the electrical energy into heat, warming the surrounding fabric.
2.4 Adjustable Heating Settings
Most heated vests offer multiple heating settings, typically High, Medium, and Low. These settings allow the wearer to adjust the level of warmth according to their preference and the prevailing temperature. The control panel or power button on the vest enables the user to cycle through the different heating settings.
2.5 Operational Indicators
Many heated vests feature operational indicators such as flashing lights. These indicators can provide information about the vest’s status, such as whether it is powered on or off, or which heating setting is currently active.
The battery pack, heating elements, adjustable settings, and operational indicators are composed into the heating system for the heated vest to provide adjustable warmth for the wearer. The vest can be used in various cold-weather activities or environments to provide comfort and help regulate body temperature.
3. 5v vs 7.4V Heated Vest, Which One Is better？
3.1 Heating Zones
In terms of heating zones, 7.4V heated jackets have an advantage over their 5V counterparts. They offer 30% larger heating zones and a greater number of heating elements. While a 5V heated vest typically has three heating zones, a 7.4V vest can feature five to six. The larger coverage and increased number of heating zones ensure that more areas of your body receive warmth, providing a more encompassing and cozy experience.
Compared to 5V heated vests, the 7.4V versions deliver more warmth due to their larger and more numerous heating zones. With a 7.4V vest, you can confidently venture out into the winter chill without longing for the warmth of your bed. It feels as if you have a cozy stove nearby, enveloping you in comforting warmth while warding off any biting cold.
3.2 Output Power
The 5V battery is an earlier product series, offering a 10,000mAh capacity and two USB ports (5V/2.1A output and 5V/3.0A output) for heated vests and charging smart devices. This battery can power the vest for 8-10 hours. As technology has advanced and customer experience has improved, a lightweight 7.4V battery has emerged. The 7.4V battery pack has a capacity of 5000mAh and can last for 8-9 hours on low settings. Equipped with a 7.4V/2.1A high-output DC port, it can provide heat to 5-6 heating elements simultaneously, ensuring even heat distribution across all heating zones due to its higher power output.
3.3 Price
Generally, 7.4V heated vests tend to be more expensive than their 5V counterparts. This is primarily due to the higher cost of batteries and other components required for the higher voltage. On the other hand, 5V heated vests can offer more flexibility in terms of sales strategy, with the option to sell the product with or without batteries.
3.4 Compatibility
One advantage of 5V vests is their compatibility with a variety of power sources, including portable chargers and power banks, making them more versatile. Buyers can easily use standard USB power banks available in the market to connect with the product. However, a disadvantage is that buyers can also purchase batteries from other sellers, potentially leading to lower profits.
3.5 What is the Best Voltage for 5V vs 7.4V Heated Vest
The best voltage for a heated vest is subjective and depends on individual preferences and specific requirements. However, the 7 Volt rechargeable heated vest is currently considered the standard choice for many users. This voltage option strikes a good balance between power, size, and cost when it comes to heated clothing.
A typical 7 Volt heated jacket will draw approximately 1-2 amps per hour of 7 Volt power to activate the heating system. This voltage level provides sufficient heat coverage and output for most users without being overly bulky or expensive.
Higher voltage options may offer more heat output, but they can also be bulkier and require larger batteries. Lower voltage options may be more portable and have a lower risk of electrical shock, but they may provide less heat output.
The best voltage for a heated jacket is the one that meets your specific needs in terms of warmth, comfort, and convenience.
When choosing the best voltage for a heated jacket, consider factors such as the desired level of heat, battery life, portability, and intended use. It’s also crucial to review the product specifications and consider any safety guidelines provided by the manufacturer.
4. Conclusion
To determine which heating system is best suited for your needs, it is crucial to consider factors such as your desired level of heat, battery life, portability, and intended use. By collaborating with a professional factory and engaging in effective communication, you can save time and money while accelerating the growth of your business.
In our opinion, 5v vs 7.4V heated vest, which one its better depends on your specific requirements and the intended use of the vest. If you prioritize safety, longer battery life, and moderate heat output, a 3.5V vest may be suitable. However, if you require higher heat output for colder environments or more demanding activities, a 7.4V vest may be preferred.
