Why this transmitter is interesting

This FM transmitter from AlzaPower solves a common problem – how to add Bluetooth to an older car without having to change the car radio. Just plug it into the cigarette lighter, tune the car radio to the same frequency, and pair your phone via Bluetooth 5.0. It works in vehicles with both 12V and 24V electrical systems.

Features: music, handsfree, charging

You can stream music wirelessly from your phone, or play directly from a flash drive or Micro SD card (max. 32 GB, MP3/WMA/FLAC formats). The integrated microphone enables handsfree calling – you can answer, reject, or end calls with the multifunction button directly on the transmitter.

The transmitter also serves as a charger. The USB-C port offers up to 20 W (Power Delivery), while the USB-A port offers 18 W (Quick Charge 3.0). When charging both devices simultaneously, the power is limited to 15 W. The display shows the current FM frequency and also the car battery voltage – practical for an overview of its status.

Practical aspects: setup, dimensions

Setup is simple – tune both the car radio and the transmitter to the same unoccupied FM frequency (87.5–108 MHz). Pair your phone via Bluetooth, and it will connect automatically the next time you start the car. Compact dimensions of 82 × 50 × 37 mm and a weight of just 40 g mean it won’t get in the way even in confined spaces. Safety is ensured by 4-fold protection against overvoltage, overload, overheating, and short circuit.

What users say

On Alza, the transmitter has a rating of 4.4 out of 5 (126 ratings) and 82% of customers recommend it. Over 5,000 units have been sold with a low return rate of 1.24%. Users most often praise easy pairing, compact design, and charging. One reviewer writes: “A cheap alternative instead of a new car radio. Simple pairing that anyone can handle.”

Critical voices appear regarding several aspects. The most common complaint concerns sound quality – it’s mono, not stereo, which might bother more demanding listeners. Some users report static noise, especially with weaker signals or interference from nearby radio stations. The display is quite bright and cannot be dimmed, which might bother some drivers at night. The quality of the handsfree microphone is, according to several reviews, average – the other party hears you “like from a tin can”.

If you want higher sound quality, there’s also the F120 model for 549 CZK or the F140 for 699 CZK. More car accessories on sale can be found in the current Alza Days.

Verdict: who it’s worth it for

If you have an older car without Bluetooth and are looking for a cheap solution for music streaming and handsfree, this discount is definitely interesting. For 324 CZK, you get Bluetooth 5.0, 20W charging, a card reader, and a battery voltage meter. On the other hand, if sound quality matters to you or you need stereo, it’s worth considering more expensive models – although at this price, it’s a reasonable compromise.
