Czechs love this charger from Alza. It has two ports and costs only 209 CZK on sale

Looking for a sensible charger with two ports that won’t cost you more than 250 crowns? The AlzaPower Compact A530 has now dropped from 299 CZK to 209 CZK with code ALZADNY30, with over 100,000 units sold in total and users giving it an average rating of 4.7 out of 5.

Quick summary:
✅ Makes sense if you want one inexpensive charger for your phone, tablet, headphones, and similar small electronics, ideally with two ports.
⚠️ Consider if you want full power when charging two devices simultaneously – when both outputs are used, the total power drops to 15 W.
💡 For 209 CZK, it’s one of the cheapest reasonably equipped 20W chargers with two ports on the Czech market.

Why this charger is so popular

AlzaPower Compact A530 is not a new product, but rather a proven classic – the number of units sold has exceeded 100,000, and 94% of customers recommend it. A return rate of just 0.43% indicates that it works without problems for most users. This is a clear signal for a charger in this price range.

The main draw is simple: you get two outputs in a single body and don’t need to carry two separate chargers. Besides the modern USB-C port with 20 W power, you’ll also find a traditional USB-A with 18 W power, which is useful if you still have older cables or accessories with a USB-A connector.

Key parameters explained in plain language

20W power on USB-C is today’s standard for regular mobile phone charging – it suits iPhones and most Androids, makes life easier with tablets, and easily handles wireless headphones, e-readers, or small power banks. The charger supports the main fast charging protocols: Power Delivery 3.0, Qualcomm Quick Charge 3.0, Samsung Adaptive Fast Charging, Huawei FCP/SCP, Apple 2.4 A, and Battery Charging 1.2.

An important detail worth knowing beforehand: you only get the full 20 W from the USB-C port, and when both outputs are used simultaneously, the total power drops to 15 W (5 V / 3 A). This is fine for parallel charging of a phone and headphones, but two more demanding tablets won’t get full power here simultaneously.

Practical aspects: dimensions, safety, warranty

Dimensions of 31 × 81 × 28 mm and a weight of just 55 grams make the A530 an ideal travel item – it takes up less space in a backpack than keys. One user praises that the ports face upwards (not sideways like most Apple, Samsung, or Xiaomi adapters), so the cable doesn’t get in the way in a crowded socket with several appliances.

AlzaPower doesn’t skimp on safety: the charger has quadruple 4safe protection against short circuit, overvoltage, overload, and overheating, and the body is made of flame-retardant plastic with the UL94 standard. Power consumption without load is 0.1 W, so you don’t have to frantically pull it out of the socket. Plus, you get a 36-month warranty, which is not a given for a charger in this price range.

What users say

With 738 user reviews and a rating of 4.7 out of 5, this is one of the best-documented products in its category. Positive feedback most often highlights the price/performance ratio, compact dimensions, two ports, and the fact that the charger reliably works with iPhones and Samsung devices, including wireless charging pads (confirmed, for example, in combination with a Fixed MagSafe pad).

However, repeated complaints include audible hum or whistling during charging – several users state that it disturbs them at night on their bedside table. A few reviewers reported that the USB-C port stopped working after several months and they had to claim a warranty or buy a second unit. There are also warnings that in sockets without covers, the A530 tilts slightly due to its own weight. A minor detail, but good to know in advance.

Another recurring criticism: when charging two devices simultaneously, it sometimes charges slowly or doesn’t detect one of the devices correctly. This is directly related to what the manufacturer states in the specifications – you only get full power when using one port independently.

When it doesn’t make sense

If you need to charge a laptop (at least 65 W), a much more demanding tablet like an iPad Pro, or two powerful mobile phones simultaneously without compromise, the A530 won’t be enough – in such a case, the AlzaPower Ultimate X500 (67 W) or X620 (100 W) model makes more sense. Similarly, if you want GaN technology and maximum miniaturization, you’ll find more modern variants directly within the AlzaPower family.

Conversely, for 209 CZK as a secondary charger for the office, by the bed, by the sofa, or for travel, the A530 is hard to replace in its category. You typically won’t find the combination of USB-C and USB-A, support for fast charging protocols, and a 36-month warranty at this price elsewhere.

Verdict: who the A530 is worth it for

The AlzaPower Compact A530 is a reliable workhorse charger for everyday use – phone, tablet, headphones, small electronics. One hundred thousand units sold, a rating of 4.7 out of 5, and a return rate of only 0.43% speak for themselves. For the promotional price of 209 CZK with code ALZADNY30, you get two ports, broad fast-charging support, and a three-year warranty, which is a very solid package at this level. If you need a secondary charger or a travel unit, this discount is probably the most sensible choice in the category.
