Czechs love this car charger. Alza now offers it on sale for 120 CZK

A car charger is often a cheap accessory, but it’s easy to encounter poor quality plastic and mediocre performance. AlzaPower X520 is one of the best-selling items in its category, and with code ALZADNY50, it drops from 349 CZK to 120 CZK. That’s even less than it cost in the previous sale (175 CZK).

Quick summary:
✅ Makes sense if you want a cheap and durable car charger for two USB-A devices (typically a mobile phone and navigation simultaneously).
⚠️ Consider if you need USB-C Power Delivery – the X520 only works via USB-A, and no cable is included.
💡 For 120 CZK, it’s one of the best-rated cheap items in its category – 4.8 out of 5 and over 20,000 sold.

Why this car charger is interesting

Most car chargers for a few hundred crowns are made of plastic. AlzaPower X520 relies on an aluminum body, which dissipates heat better and is frequently cited in reviews as the main reason for satisfaction. In addition, it offers two USB-A ports and a combined output of up to 36 W, so you can charge two devices simultaneously – typically a mobile phone with navigation. For 120 CZK with code ALZADNY50, you get a product that over 20,000 people have actually purchased.

What it offers in practice: ports, performance, installation

Technically, it features 2× USB-A with DC5V/2.4 A output, a total current of 4.8 A, and a maximum combined output of 36 W. It includes 4Safe quadruple protection against short circuit, overvoltage, overload, and overheating, so the risk of phone damage is low. The dimensions of 60 × 25 × 25 mm are compact, and thanks to support for both 12 V and 24 V, the charger works in cars, trucks, and caravans.

However, note that no cable is included – you must use your own depending on your device. A practical detail from reviews: the body is designed for a classic cigarette lighter socket, so it might not fit into some smaller “Size A” type sockets. Before purchasing, it’s therefore worth checking what type of socket you have in your vehicle.

What users say

A rating of 4.8 out of 5 from 427 reviews is above average for an accessory, complemented by a low complaint rate of 0.68% and the fact that 95% of customers recommend the product. People most often praise the metal design, charging speed, and that the charger holds firmly in the socket and does not overheat even during extended use.

There are also criticisms, and it’s worth knowing them. Some users are concerned about the LED ring, which stays lit even after the car is turned off and some find it too bright. A few reviewers encountered the charger falling out of a specific socket or received a faulty unit. And if you want to charge more demanding devices, 18 W per port might not be enough – several people therefore switched to a more powerful USB-C variant.

When it doesn’t make sense

If you want USB-C with Power Delivery and the highest possible charging speed for modern phones, the X520 is not ideal – it only works via USB-A. In that case, a USB-C model with PD makes more sense. Furthermore, reconsider purchasing if you are bothered by a constantly lit LED or if your car has a smaller type of socket that the wider body might not fit into.

Verdict: who it’s worth it for

For 120 CZK instead of 349 CZK, this is a reasonable purchase for anyone who wants a durable car charger for two USB-A devices and does not need USB-C Power Delivery. The combination of an aluminum body, a rating of 4.8, and over 20,000 units sold is a decent assurance for a cheap accessory. However, more demanding users and owners of phones with fast USB-C charging would do better with a PD model.

Are you looking for a simple USB-A car charger, or do you need USB-C Power Delivery?
