Car charger for 120 CZK. This one from Alza charges two phones simultaneously and looks good too

Car chargers for 12V sockets are small things, but a quality piece will last for years. The AlzaPower Car Charger X520 currently costs only 120 CZK with the discount code ALZADNY50. Originally, this model was priced at 349 CZK, but in the last year, it has been on sale more often – before this discount, it was 175 CZK.

Quick summary:
✅ Makes sense if you need a reliable car charger with two ports for a minimal price.
⚠️ Consider if you need USB-C or higher power than 18 W per port – then opt for the X525 model.
💡 For 120 CZK, you get a metal charger with Quick Charge 3.0 and proven reliability among thousands of customers.

Why this charger is interesting

AlzaPower X520 is among the best-selling car chargers on Alza – over 20,000 units sold speak for themselves. For a price where you’d otherwise buy a plastic no-name charger, you get an aluminum body with quality craftsmanship. The metal construction isn’t just about design – it dissipates heat better and feels more robust than cheap plastic alternatives.

Performance and fast charging

The charger features two USB-A outputs, each with up to 18 W of power and Quick Charge 3.0 support. The total combined power is 36 W, allowing you to charge two phones simultaneously. When using a QC 3.0 compatible device, charging is up to 75% faster than with conventional adapters.

Output specifications: 5 V / 2.4 A, 9 V / 2 A, or 12 V / 1.5 A – the charger automatically recognizes the connected device and adjusts the output. Efficiency reaches 90%, meaning minimal losses and less heating.

Practical aspects: construction and compatibility

The charger works in both passenger cars (12 V) and trucks and caravans (24 V). Dimensions of 60 × 25 × 25 mm ensure that it barely protrudes from the socket when inserted. A subtle LED ring indicates charging – according to reviews, it’s not distracting but helps with orientation in the dark.

4safe safety protections guard against short circuit, overvoltage, overload, and overheating. No cable is included in the package – if you don’t have one, you’ll need to purchase it separately.

What users say

On Alza, the charger has a rating of 4.8 out of 5 (463 ratings) and 95% of customers recommend it. The return rate is very low – only 0.63%. Users repeatedly praise the metal craftsmanship, charging speed, and the fact that the charger holds well in the socket. Several reviews mention using one unit for several years without issues.

Critical voices appear occasionally. Some users report that the LED ring stays lit even when the engine is off – which can be annoying in some cars with a constantly powered socket. A few reviews mention that the charger did not fit into a narrower 12V socket (the so-called “Size A”) – the standard for cigarette lighters is wider. One user recommends opting for the X525 model with USB-C and 30 W power for more demanding use.

When it doesn’t make sense

If you need a USB-C output or higher power for modern phones with fast charging over 20 W, this charger will not be the ideal choice. In that case, consider the X525 model with the same design, but with a USB-C port and 30 W power for 279 CZK. Also, if your car has a narrower type of 12V socket, there might be an issue with insertion.

If this particular model didn’t appeal to you, but you’re looking for other car accessories on sale, you can also browse the current Alza Days, where other discounted products regularly appear.

Verdict: who it’s worth it for

If you’re looking for a reliable car charger with fast charging and don’t want to spend hundreds of crowns, the AlzaPower X520 for 120 CZK is a sure bet. Over 20,000 units sold and a rating of 4.8 out of 5 prove that it’s a proven product. Metal body, two USB-A ports with QC 3.0, and a low return rate – all for the price of one lunch. Conversely, if you need USB-C or higher power, opt for a newer model.
