Xiaomi ROIDMI 3S Bluetooth Music Car Charger

Intro

The RoidMi car charger is a gadget that every car needs. Especially when you have a slightly older car like the one my wife has, with an integrated radio-cd player without built-in Bluetooth. This transceiver gives you the opportunity to connect your phone and play music or make/receive calls through your radio. Besides this functionality, this device is a powerful fast-charger.

It sounds great, so let’s see if it can live up to its expectations.

Build Quality and Design

The design is clean and simple. It looks like every USB – car charger that’s available on the market. The feel of the device is solid. The car charger comes in the color black, which is different from the white look that we are used to with Xiaomi products. This makes the car charger easy to blend in.

Usability

In a few steps, you are able to pair your phone with the charger.
Put the charger in your 12V outlet in your car. Tune your car radio to the default frequency (96.4 FM). On this frequency, the transmitter sends the Bluetooth audio to your car radio. Simple but effective. If you let the charger in your car and the Bluetooth on your phone on, you are ready to go, every time you enter your car.

There is an app (RoidMi) which you can download from the app store/play store. With this app, you can change the default frequency in case of white noise on channel 96.4. You can change to any frequency that gives no white noise.

Bluetooth streaming and calling

The setup was very simple and from now on music and calls are forwarded from your phone to your car radio. The quality of the music is good, but it can happen that you need to change the default frequency in some areas.

Charging

De RoidMi 3S is equipped with 2 illuminated USB ports. Both can be used to (fast) charge any device. You immediately notice the difference from other car chargers. This one is much and much faster. You have the luxury to charge two devices at the same time because of the dual USB-port. This doesn’t affect the fast charge function, it charges just as fast as when you have plugged-in only a single device.

Alternatives
