Xiaomi is not only synonymous with good smartphones. It is something that the directors of the Asian company have always wanted to make clear: “Pwe'd be selling 10 billion smartphones and we wouldn't make a single penny in profit”Declared Hugo Barras, world vice president of Xiaomi in 2016. Where they really make money, is with the rest of accessories and gadgets that they put on the market. Devices like this Xiaomi Roidmi 3S, a USB car charger with a clearly differentiating functionality.
Xiaomi Roidmi 3S, a USB charger reminiscent of the classic multimedia cassette tapes for the car
If we say that Xiaomi's Roidmi 3S reminds us of old car cassettes, it is not because they have this shape. Quite the contrary. At first glance it is a simple USB charger with 2 input portsthat we connect to the car's cigarette lighter. Pretty nice design, yes, but a car charger, all things considered. No more no less. Then?
Music via FM frequency and the integrated chip of the Roidmi 3S
Do you remember how years ago special cassettes were used for the car that were used to connect a CD player or even a pendrive? Thus, we could listen to musicEven though we didn't have a disk drive or USB in our old wagon.The Roidmi 3S takes up that same concept, offering 2 very different functions:
- USB car charger with 2 input ports.
- Bluetooth 4.2 with FM frequency broadcast.
In this way, we can listen to music or our favorite podcast through the car speakers. As simple as connecting our Android or iPhone to the Roidmi 3S via Bluetooth and tune the car radio to the frequency of 96.4MHz.
We can also use the Roidmi app to change the broadcast frequency (87.5 - 108.0MHz) and make some other adjustments. It's free and available for both Android and iOS.

Opinion and final assessment of the Xiaomi Roidmi 3S
[P_REVIEW post_id = 10819 visual = ’full’]
In general, we find a device that stands out notably above the rest of USB chargers for the car thanks to its Bluetooth function and music transmitter. It is slightly more expensive than the rest of the chargers, but it is compensated a lot thanks to its pack of specifications and a quality finish that is more than notorious that we will hardly find in other similar devices.
