This charger can handle two devices simultaneously and costs only 299 CZK. It has excellent reviews

Looking for a small travel charger that can charge two devices simultaneously? The AlzaPower G351CA currently costs just 299 CZK with discount code ALZADNY25. The product has over 10,000 units sold on Alza and a rating of 4.8 out of 5, making it a proven choice.

Quick summary:
✅ Makes sense if you need a compact travel charger with fast charging support and two outputs.
⚠️ Consider if you need to charge two devices simultaneously at full power – when both ports are used, the power drops to 15 W.
💡 For 299 CZK, you get a GaN charger with wide compatibility, which is an above-average offer in this price range.

Why this charger is interesting

The AlzaPower G351CA targets users who want one cheap charger for everything – phone, tablet, headphones, power bank. Thanks to GaN (gallium nitride) technology, the charger is significantly smaller than classic adapters with the same power. Dimensions of 35 × 69 × 32 mm and a weight of just 42 grams mean it practically takes up no space in a backpack or handbag.

Performance and compatibility

The charger features two outputs: USB-C with up to 20 W power and USB-A with up to 18 W power. It supports a wide range of fast charging protocols – Power Delivery 3.0 with PPS, Quick Charge 3.0, Samsung Adaptive Fast Charging, Huawei Fast Charging, and Apple 2.4 A. This means it will quickly charge most current phones regardless of brand.

It’s important to know that when both ports are used simultaneously, the power drops to 15 W (5 V / 3 A). This is sufficient for overnight charging of two devices, but if you need to quickly recharge both a phone and a tablet at the same time, it will be slower.

Safety and efficiency

The charger includes 4safe safety protections – against short circuit, overvoltage, overload, and overheating. The body is made of flame-retardant material meeting the UL94 standard. Smart IC technology automatically detects the connected device and adjusts the output power to its needs.

The charger’s efficiency exceeds 87%, and its no-load power consumption is just 0.1 W. You can therefore safely leave it in the socket without it unnecessarily drawing electricity. The input voltage of 100–240 V means it works worldwide.

What users say

On Alza, the charger has a rating of 4.8 out of 5 (185 ratings) and 94% of customers recommend it. The return rate is very low – just 0.53%. Users most often praise its compact size, charging speed, and the fact that it doesn’t overheat too much even under full load.

However, there are also critical voices. Some users report slight whistling or buzzing. Others point out that when a second device is connected or disconnected, there is a brief interruption on the first port – which can be annoying if you use the charger, for example, to power a lamp. Several owners of Samsung phones (S23, S24 FE) also mention that their phone does not recognize fast charging, even though it should according to specifications.

When it doesn’t make sense

If you need to charge two devices simultaneously at full power, this charger will not be the ideal choice – when both ports are used, the power drops. Similarly, if you have a newer phone and insist on super-fast charging, it might be better to opt for an original manufacturer’s adapter or a more powerful variant. The package also does not include a cable, so if you don’t have one, you’ll need to purchase it separately.

If this particular model didn’t appeal to you, but you’re looking for a charger on sale, you can also check out the current Alza Days, where other discounted chargers and accessories regularly appear.

Verdict: who it’s worth it for

If you’re looking for a compact travel charger with two outputs, the AlzaPower G351CA for 299 CZK offers a solid price/performance ratio. GaN technology ensures small dimensions, and wide compatibility covers most phones and tablets. Conversely, if you need higher power or exclusively charge a Samsung with a requirement for super-fast charging, consider more powerful alternatives.
