Czechs love it! Great Alza desk charger has 3x USB-C and up to 100W power, now beautifully discounted

One charger for a laptop, tablet, phone, and watch. AlzaPower MG8103CA thanks to GaN technology, compressed 100W power into a compact body with dimensions of 99 × 76 × 22.5 mm. And a one-meter power cable is included in the package – no large brick sticking out of the wall.

Four ports, one hundred watts

The charger features 3× USB-C and 1× USB-A. The two main USB-C ports support up to 100 W (20V/5A) with Power Delivery 3.0 and PPS – enough to power a MacBook or another powerful laptop. The third USB-C offers 65 W, and USB-A offers 30 W.

Supported fast charging standards: PD 3.0 with PPS, QC 4.0/3.0/2.0, Samsung Adaptive Fast Charge, Huawei FCP, and Apple 2.4A. Practically every phone or tablet will get the maximum possible speed.

However, be aware of combinations: when multiple ports are used simultaneously, the power is redistributed. For example, USB-C1 + USB-C2 + (USB-C3 + USB-A) = 45W + 35W + 15W. You can find the combination table in the product gallery – study it before purchasing, and it is visible in the image above.

GaN technology = smaller and cooler

Gallium nitride (GaN) replaces silicon and allows for higher efficiency in smaller dimensions. This charger achieves over 91% efficiency. Standby power consumption is only 0.3W, and the body is made of flame-retardant material meeting the UL94 standard.

Smart IC automatically detects the connected device and adjusts the power. 4Safe safety protections guard against overvoltage, overload, overheating, and short circuit. Input voltage of 100–240V means worldwide compatibility.

What 126 customers say

It has a rating of 4.7 out of 5 on Alza, over 2,000 units have been sold, 91% of customers recommend it, and the complaint rate is only 0.53%. “I was looking for a quality power source for a docking station to power a laptop, speakers, display – and it works like a charm,” writes a satisfied customer.

Most frequent praise: power cable instead of a large brick. “I hate those big bricks that plug directly into the socket, so this is great.” Its compact dimensions and design are also appreciated on a crowded desk.

Main criticisms are directed at the power cable – several customers report that it wiggles or falls out of the charger. “The power cable falls out, bad contact,” complains one of them. Others mention a brief interruption in charging when another device is connected – however, this is normal behavior for multi-port chargers due to mode detection.

One customer had problems with a MacBook (“it showed a plug logo and a message that the battery was not charging with the adapter”), but most reviews confirm problem-free charging of Apple devices and laptops. Heating under higher load is normal – “it gets warm, nothing terrible, but you definitely won’t stick it anywhere.”

The original price was 1,299 CZK and now with code ALZADNY25 it costs 974 CZK. For a 100W GaN charger with four ports, support for all common fast charging standards, and a cable included in the package, it’s a fair price. However, study the power combination table – when all ports are fully occupied, the 100 W will be distributed among the devices.

How many devices do you charge simultaneously? Is one port enough for you, or do you need a multi-charger?
