In an age where mobile device batteries are often a real headache, leaving the user without power when it is most needed, the car can make new profits over and above its basic transport task and not even its manufacturer needs to include them in the factory. For example, Xiaomi Roidmi 3S includes a charger and wireless audio player in one accessory.
Xiaomi Roidmi 3S is an accessory designed specifically for the car and seeks to equip any vehicle, even the oldest, with the most basic and useful intelligent functions that can be found in these times. From being able to charge the battery of two terminals at the same time via USB as well as receiving wireless audio transmission from Android and iOS mobile phones.
High quality materials
Xiaomi didn’t want to offer a visualization and complicated use for the users, so in terms of design, a more traditional style has been chosen with a circular plastic case that has two types of width depending on the area of its structure. Logically, the upper end is where the USB port input for charging has been located.
However, the Roidmi 3S charger also promises an internal architecture with well-distributed, organized and high quality components to ensure that its service life is truly long. In official figures, Xiaomi indicates that the dimensions of the accessory are 53 mm long and 23 mm wide, while the weight is 400 grams.
Finally, the integrated chip for this occasion has a series of parameters to control the input and output current, more precisely with an eight-circuit protection that prevents the appearance of problems such as overheating, short-circuits, voltage figures higher or lower than the supported standards, etc.
Charging options and service life
Specifically regarding device charging, the user has two USB ports available that can be used without major problems. In total, the amount of output power supported is 3.4A, while if you only want to recharge a single piece of equipment, you can reach 2.4A, more than enough for most terminals (including tablets).
On the other hand, from Xiaomi they want to leave those who use this Roidmi 3S charger alone, because they have chosen components from the main manufacturers of the market in countries such as Japan, Great Britain, the United States, etc., and even more than 200 tests have been carried out to avoid the appearance of any problem in their performance.
The charger has a lifespan of approximately 20 thousand hours continuous, in addition to inserting and removing the car accessory about 100 thousand times or plugging devices into its USB ports up to 500 thousand times before needing a replacement.
Available music options
Xiaomi Roidmi 3S clearly makes use of the Bluetooth 4.2 standard to make wireless connections between any device that is on hand and the charger. There are several audio functions available, including an integrated microphone that makes it easy to use handsfree in the car when a call is received or placed on your phone.
Roidmi App is the name of an official Xiaomi application for Android and iOS mobile phones that allows you to control everything that happens with your device, including notifications about the power load situation. Specifically in the field of music, it not only plays audio stored locally in the terminal, but can also be synchronized with streaming music services and online radios.
As if this were not enough, there is also an FM radio chip that makes it fully compatible to receive all the frequencies available in the city. It even has advanced electro-acoustic technologies that ensure audio reception in its best quality and noise cancellation.
