It burns great
Runs for about 10 mins on full power before it overheats.

it really does deliver up to 100W
Doesn't overheat at all on low power settings, unlike my old 200W Alzapower Ultimate.
According to my measurements, it's very efficient (up to 96% when I was only drawing 20W from it)
Beautifully small for 100W
simply the latest GaN generation
Seems very well-made
supports a load of protocols
theoretically up to 105W (21V 5A)
Having two ports is brilliant.
Excellent price of 700 Kč (was also available for 500 during the alza days sale)
So far I haven't found any device that it couldn't connect with/charge.
only 98g
Under a higher load (around 55-60W), it got quite hot, specifically up to 68°.
Considering how small it is, it weighs 98g, but even that's fine.

I wanted this as a travel adapter for my laptop, but for some reason, it only started to trickle charge (or rather, maintain the charge of) my 100W laptop. It managed to charge my phone at 100W, but unfortunately, it doesn't meet my needs for travelling, so I'm returning it.

Hello, thank you for your feedback. The 100W power is the maximum output of the main USB-C port. However, with a long-term draw of 100W, the electronics gradually heat up. The charger therefore automatically reduces the power output upon reaching a certain temperature to maintain a safe operating temperature and prevent excessive thermal stress on the components. This is the trade-off for its exceptionally small size – current technology allows for very high power in a small body, but with a long-term constant load of 100W, it is necessary to thermally regulate the power. In practice, the power output then fluctuates around 60–80W depending on the conditions and ambient temperature. Therefore, 100W is not just a marketing figure. It is the maximum available power that the charger can achieve, and during long-term high loads, it protects itself and the connected device by regulating its output. Thank you for your understanding. We believe that despite this characteristic, you will appreciate the combination of high power, GaN technology, and very compact dimensions. Thank you and have a nice day, Ondřej - Alza expert

After about fifteen minutes at full 100W power, it heated up to an estimated 40°C and reduced its output. I discovered this using a TP-link Tapo smart plug; at full power, it initially drew 102W (the 2W are probably losses), and after noticeably heating up, the power draw dropped to 64W. Tested at a normal room temperature of about 22°C. Only one port was used the entire time.
size
2 ports
Feels solid to the touch
heats up above 40°C
Reduces performance

Compact and lightweight
Doesn't stop charging, even when it overheats
The 3-year warranty will definitely come in handy
Holds 100W for only the first 15 minutes or so.
Then the power drops to 65W
The temperature reaches nearly 100°C when charging a laptop after a few hours at 65W.
Only for 200 to 240 VAC, will mainly only work in EU countries

100W for very fast charging and 20W for slow charging and saving the battery, brilliant.
