Which Battery Capacity is Larger: 10000mAh, 14400mAh, or 16800mAh?


The surge in popularity of heated apparel has led to a proliferation of battery options in the market. Amidst this abundance, discerning the most suitable battery becomes paramount. This passage aims to demystify the realm of battery capacity, focusing on three prevalent options: 10000mAh, 14400mAh, and 16800mAh.

Exploring Battery Capacity

Heated apparel, a revolutionary solution for warmth-seekers, has attracted numerous brands like Venustas into the fray. However, before delving into the world of heated clothing, understanding battery capacity is imperative.

Battery power heated apparel

Typically, a battery powers heating elements to provide warmth. Surveying the market, we encounter various battery types tailored to diverse needs and preferences. Amidst this array, misconceptions abound, particularly regarding the correlation between battery capacity and extended usage time. Some manufacturers assert that higher capacity batteries equate to prolonged heating hours, a fallacy that we aim to dispel.

Understanding mAh, V, and Wh: The Basic of Battery

Milliampere-hours (mAh), Volts (V), and Watt-hours (Wh) are common units used to describe battery performance and energy capacity. Understanding these units is crucial for selecting the right battery and using it effectively.


  • Milliampere-hours (mAh): mAh measures the electrical charge capacity of a battery. Specifically, it represents the amount of current that a battery can supply for one hour before it is fully discharged.
  • Volts(V): V, also known as electric potential difference, is the unit of measurement of voltage. Normally, higher voltage means the battery can deliver more power to the device.
  • Watt-hours (Wh): Wh is used to measure the amount of energy that a battery can provide at a certain power level for a certain time. For example, a 20 Wh battery can provide 20 watts of power for one hour.

    Now we have a clear understanding of these three units. In the purchase of a battery, we always tend to focus on the battery capacity (mAh) while putting the volts (V) and watt-hours (Wh) away. It’s unreasonable.

    Watt-hours(Wh) is a significant consideration that consumers need to take into account. The higher the watt-hours, the larger the battery capacity. That also means the battery features excellent endurance capacity

    How to Calculate the Watt-hours(Wh)?

    To calculate the Wh of the battery, it’s crucial to know the mAh and V. We usually use this formula:

    Watt-hours(Wh) = Milliampere-hours (mAh) * Voltage (V) /1000


    Now, let's return to our main focus:

    Why Venustas10000mAh@7.4V surpasses 16800mAh@5V, 5000mAh@12V, and 14400mAh@5V batteries. To clarify this, let's apply the formula for a comprehensive understanding. To grasp the logic behind these calculations, it's crucial to consider two key points:

    1.The true voltage of a 5V battery available in the market is typically 3.7V, as most lithium-ion batteries have a nominal voltage of 3.7V.

    2.Some batteries labeled as 7.4V with capacities of 14400mAh or 16800mAh are actually calculated based on a 3.7V (5V) standard.

    Now, let's delve into the specifics:

    • Venustas 10000mAh@7.4V Battery:


    • 16800mAh@5V Battery:


    • 5000mAh@12V Battery:


    • 14400mAh@5V Battery:


    Therefore, in summary, the order of superiority is Venustas10000mAh@7.4V(=20000mAh@5V) > 16800mAh@5V> 5000mAh@12V(=16216mAh@5V) > 14400mAh@5V, with the respective energy capacities of 74Wh > 62.16Wh > 60Wh > 53.28Wh.

    From these computations, it's evident that relying solely on the battery capacity labeled by manufacturers may lead to misleading conclusions regarding running time.

    Understanding the Power of Heating Elements

    Now that we've established the impact of watt-hours on running time, let's delve into another critical aspect: the power of heating elements.

    Heated elements are equipped in the apparel to generate heat with the power of the battery. If you have a strict requirement about the heating hours, you need to check out the power of the heating elements determined by the size, quantity, and temperature. Theoretically, the higher the temperature, the higher the power of the heating element, resulting in a shorter battery usage time. Additionally, a greater number of heating elements with larger coverage areas could accelerate the battery level.

    Heating elements

    In a word, it’s hard to keep the balance of a high level of warmth and long-lasting running time. If you want your clothes to be warmer, the requirement of the battery endurance capacity should be decreased. On the contrary, if you look for a battery with higher watt-hours, you should lower your standard for the power of heating elements. Plus, batteries of higher watt-hours usually come with an increased weight and larger size. So, it’s essential to make a purchase decision based on your preference and intended usage.

    Venustas Battery Option

    Through ongoing development and innovative strides, Venustas has firmly established itself as a frontrunner in offering a comprehensive selection of battery options. Each battery is thoughtfully designed with distinct features to cater to an array of individual requirements.

    Venustas Battery
