Great value for money: Alza is selling off a 40,000mAh power bank with 100W charging for a steal!

While mobile phones and tablets have seen significant improvements in battery life, laptop users are still often limited to just a few hours of operation. If you are among those who need to work on the go or in the field without access to an electrical outlet, a quality power bank with high output can be the solution. The AlzaPower Metal 40000mAh Fast Charge + PD3.0 (100W) is now available on Alza for 1,294 Kč with code ALZADNY35, which represents a 35% discount compared to the regular price of 1,990 Kč.

Capacity and performance that will please demanding users

The AlzaPower Metal impresses at first glance with its elegant metal design, which is not only aesthetic but also provides better heat dissipation and increased durability. It offers an impressive capacity of 40,000 mAh (148 Wh), which should be enough, for example, for 2 full charges of a typical laptop or more than 7 charges of an average smartphone. The only drawback of such high capacity is that the power bank cannot be taken on board an airplane without special permission (the limit for air transport is 100 Wh).

What sets this power bank apart from many other models on the market is its support for high charging output of up to 100 W. This means it can charge even powerful laptops at full speed. It also supports all important fast charging standards – Power Delivery 3.0, Qualcomm Quick Charge 3.0, Samsung Adaptive Fast Charge, and other protocols for fast charging of various phone brands.

Connectivity and practical features

The AlzaPower Metal offers three charging ports – one USB-C supporting both input and output power up to 100 W, and two USB-A ports with a maximum output of 18 W. The power bank itself can be charged either via USB-C or Micro USB. Depending on the charger used, a full charge can take from 2 to 12 hours – with a 65W charger, expect around 6-7 hours.

Thanks to Smart IC technology, the power bank automatically detects the connected device and optimizes power distribution. Safety is ensured by six-fold protection against overvoltage, overload, short circuit, overheating, overcharging, and deep discharge. There is also a four-LED battery status indicator, which provides a basic overview of the remaining capacity.

What do users say about it? Mostly praise, but some complaints too

In almost three years on the market, the AlzaPower Metal power bank has accumulated dozens of user reviews, offering a very good insight into real experiences. Most customers appreciate its high capacity and 100 W output, which can indeed power even more demanding laptops. Roman from Liberec, for example, states in his review that he bought it for its «huge capacity» and jokingly adds that «in an emergency, it can be used as an improvised blunt weapon» – a reference to its weight of 774 grams.

Price: 1,294 Kč

Other users confirm that the power bank really charges laptops: «The laptop lasted almost a full day on it at full performance,» writes Andrzej from Prague. Jan from Teplice appreciates that it «can charge my laptop via USB-C (it draws 65 W)» and also that it «charges quickly from the car charger (also 65 W)».

Among the main criticisms, the weight and dimensions of the power bank are most often mentioned. Martin from Vernířovice describes it as a «brick like hell,» which is the price for the high capacity. Several reviewers also mention problems with charging the power bank itself – some cannot charge it, or problems with functionality appear after a certain period of use.

Petr from Prague points out that the capacity «corresponds more to 100 Wh, max. 110 Wh» instead of the stated 148 Wh, but adds that «for a price around 1,500 Kč, it’s a good buy.» Some users would also appreciate a second USB-C port instead of Micro USB, as David from Prague notes: «Why Micro USB and not 2× USB-C?»
