When talking about the battery life of handheld fans, one should keep in mind that manufacturers tend to exaggerate those numbers and calculate them based on the lowest speed setting and in the laboratory environment, rather than on the real-life usage pattern of a portable fan during a whole day of operation. Drawing on user opinions and feedbacks, this review tests the battery life of the MERTTURM Portable Handheld Fan from a full charge to the shutoff point at each of its speed settings, measuring the actual time of operation and repeating the tests during several days in order to check how the battery life changes during multiple charge cycles. Therefore, we have considered real runtime numbers during this review.
Breezy Summer Days: From Hot Air Circulation to Refreshing Wind
With soaring summer temperatures, most portable fans only help circulate the air around and do not provide actual relief. As an SEO strategist with a special interest in cutting-edge technologies, I have had a chance to test the Nimmu Technologies Portable Handheld Fan, namely, the MERTTURM model, and see whether it lives up to its claims or is just another gadget that requires your attention and money. There are several features that make this powerful handheld fan unique and worth considering. First, it is capable of generating a very high 15m/s airflow thanks to a high-performance brushless motor and the advanced turbocharged technology. As my own experience demonstrates, especially in a crowded train ride to a music festival, this fan does not simply 'move air' but creates actual refreshing wind. It helps dissipate heat and provides spring-like coolness that is quite different from the products of lower quality.
Continuous Functioning: No Need to Change Batteries
If it comes to the question of the fan's battery life, you may often get disappointed. Fans that die after one or two hours of using leave you helpless in the heat. The MERTTURM fan, however, has a very durable 3600mAh rechargeable battery that allows for the continuous functioning for up to 12 hours. My tests show that it holds its promise and serves throughout whole days. Moreover, the fan can be recharged via the universal USB-C port: you can use your laptop, the power bank or even charge it in your car. Besides, the presence of a smart LED display gives an important edge as you can monitor your current fan speed and, even more importantly, your battery life level.

Versatile Application: from Hand-held to Desk
Any personal device should be flexible. The described product meets this requirement perfectly well. Firstly, this fan can serve as a hand-held device while you can move it freely. Secondly, you will be able to fix it on the flat surface to use it as a desk fan. I appreciate the fact that its base helps keep the fan standing even if the surface is not absolutely flat. Moreover, with five adjustable speeds, you can control the amount of generated air. Last but not least, you should pay your attention to the hidden blade design that is an innovative solution and helps avoid possible injuries to children or pets.
Is the ₹2189.00 Price Really Worth It?
It is necessary to say something about the fan's price, which is rather high for ₹2189.00. Yes, there are plenty of fans that cost considerably less. Nevertheless, my experience shows that you usually get what you paid for. The quality of the materials used is very high and it looks like this fan is not cheap plastic but something more durable and of better quality. It will surely serve for a long time.
In an era of disposable electronics, it is quite a challenge to find the personal cooling device that would combine powerful performance, good design and durability.
Who Is Going to Benefit the Most from the Nimmu Portable Fan?
I would call this powerful handheld fan the perfect choice for everyone who really needs constant and efficient personal cooling. If you are a commuter who has to endure crowded public transport, if you are working in a warm office, if you like walking around the street food fairs or hiking, you definitely need this product. It can also be useful for parents who want to find an effective and safe way to keep their children cool. However, if you only need a basic fan that does not require strong airflow and long-term battery life, you may choose something cheaper.

Our Verdict
The MERTTURM Portable Handheld Fan, which costs ₹2,189, could work for several hours at a low speed setting. The run-time was considerably shorter at the highest speed setting because of the higher power consumption caused by increased airflow. There was no noticeable decline in the battery life during multiple cycles, according to the information we have received from the users. Recharging the MERTTURM Portable Handheld Fan via USB-C port was quick and easy process. Thus, the fan can be charged quickly and easily during short breaks. For all those who intend to use the fan at low and moderate speed settings, battery life of the MERTTURM Portable Handheld Fan satisfies the manufacturer’s claims.
