People tend to have a lot of questions about our heated jackets and the length of time they can wear them.  Questions like: How many hours does it actually last? How can I enjoy the heat for a longer period of time? Before we answer all of that, you need a better understanding of what factors may affect heating time. Let’s dive into the specifics below.

Battery Capacity

Heated clothing is powered by a rechargeable battery. The capacity of the battery plays an essential role in the overall heating time. A battery with a larger capacity is likely to provide heat for a longer period of time. However, with the bigger battery, there are often problems that come along with it like being too heavy and too large to hold in your hand. To tackle this problem, we made our battery with increased capacity but palm-sized to ensure both top performance and convenience. 

We use the 5200 mAh battery with a power output of up to 7.4V. The total energy in the ORORO battery will be 5200 mAh x 7.4V / 1000 = 38.48 Wh. Compared to the 10400 mAh standard battery with 3.7V output in the battery industry (10400 mAh x 3.7V / 1000 = 38.48 Wh), our apparel battery provides equal energy with higher heating efficiency.

Anatomy of the Heating Elements

The heating elements’ location and how it’s being used will affect how much power is consumed, directly influencing the overall length of time the battery is on. For example, your battery tends to run out faster when charging two phones at a time or if the heat is on High all the time. 

ORORO chooses different heating locations for different apparel styles to ensure the best heating performance and to seal the warmth in for your entire body. For the padded vest, four heating elements are built in the collar, the left & right pocket and the mid-back to fit the body’s natural curve and prevent any heat loss. 

External Factors

Outside factors like temperature and weather will influence the heating time. In low-temperature conditions, the effectiveness of the discharge capacity and energy of lithium-ion batteries will be reduced. This doesn’t mean you should worry about the battery’s performance when it’s cold out. We continuously improve our battery technology every year and it’s proven to be effective against low temperatures with certification from SGS testing.

Certified to Keep You Warm

Our battery’s heating time is certified by SGS testing, an industry-standard test to ensure compliance with the battery working time. We applied to test out the working time of our battery in various temperatures, including 50 ℉, 41 ℉, 32℉, 23 ℉ and 14 ℉, all tests were shown to last far beyond the guaranteed heating time. Even in the temperature of 14 ℉, results showed our battery provided 3.3 hours of heat on high, 6.67 hours of heat on medium and 11.2 hours of heat on low.

Here’s how to preserve your battery and enjoy a lifetime of heat:

• Charge your battery at normal room temperature to ensure its full-charge capacity. Avoid charging your battery at extremely low temperatures, which will influence the efficiency of charging and its overall effectiveness. 
• Store your battery at normal room temperature and charge your battery every half year when not in use.
• Adjust to the heating level that will keep you suitably warm in different conditions. You may need your gear on High when you go outside for work in the early morning and on low when you’re in the office. Adjust for different environments to avoid wasting precious heat. 
• Always have a back-up ORORO Battery to ensure you have a fully-charged battery in hand.

We’ve been working hard to make a heated jacket that everyone can rely on. The battery is an indispensable part in achieving the best warmth of a heated jacket. The next time you’re heading out into the cold, wear your heated apparel with confidence.
