You don't see many like this. Alza started selling a power bank with a rather unusual feature

If you’re tired of constantly remembering to pack a charging cable along with your power bank, you might consider getting a model with a built-in cable. Alza has now started selling the AlzaPower Glide power bank with a retractable cable for 699 Kč. When you don’t need the cable, it doesn’t get in the way, and when you want to charge, you simply pull it out of the power bank’s body.

Quick summary:
✅ Makes sense if you want a power bank where you never have to worry about an extra cable and appreciate a clear LCD display.
⚠️ Consider that 10,000 mAh is enough for approximately 1.5 to 2 phone charges and that it only has USB-C outputs.
💡 For 699 Kč you get a new product with an integrated cable, aluminum body, and a three-year warranty.

Why this new product is interesting

This AlzaPower Glide power bank solves the most annoying thing about charging away from home: the cable you never have on hand. A 65 cm long retractable USB-C cable is hidden directly in the body – you pull it out, charge, and then slide it back into the body, where it doesn’t get in the way or tangle. Compared to earlier models with a short loop, 65 cm is enough to comfortably use your phone while charging. Plus, an elegant aluminum body and compact dimensions. For 699 Kč, it’s a fresh idea in a category where nothing significant has changed for years.

Key parameters in plain language

The capacity is 10,000 mAh (38.5 Wh), which realistically means approximately 1.5 to 2 full charges for a typical phone – due to voltage conversion losses, you never get the full 10,000 mAh into the device. Both outputs (integrated cable and USB-C port) support Power Delivery 3.0 with up to 20 W of power, as well as Quick Charge 3.0, Samsung AFC, Huawei FCP, and Apple 2.4A protocols. Be aware of one limitation: when charging via both outputs simultaneously, the total power drops to 15 W. For one phone, it’s fast; for two devices, expect a slower pace.

Practical aspects: cable, ports, charging

The main advantage is clear – you always have the cable with you and don’t need to buy anything extra or carry it separately. In addition to the integrated cable, there’s also a separate USB-C port, so you can charge two devices simultaneously. The Low Power Mode is useful, allowing the power bank to charge even headphones and smartwatches with low power consumption without shutting down due to low current. The LCD display shows the remaining energy as a percentage.

You can recharge the power bank itself via both the port and the integrated cable, and with at least an 18W charger, it takes approximately 3.5 hours. One practical note: the power bank has only USB-C outputs, no USB-A, so for older accessories with USB-A, you would need an adapter – on the other hand, it’s a modern solution that matches today’s phones. Safety is ensured by six protections against overvoltage, short circuit, overheating, and other risks.

What to watch out for

The most important thing is real-world endurance: 10,000 mAh is a capacity for topping up energy during the day, not for several days without an outlet. Anyone expecting a power bank that charges a phone four times will be disappointed – this one sacrifices capacity for compact dimensions and an integrated cable. Second thing: it’s a brand new product with no user reviews yet (only a few units sold so far), so the long-term reliability and lifespan of the retractable cable will only be proven over time. However, the three-year warranty and the option of immediate replacement at a branch mitigate the risk.

When it doesn’t make sense

If you need a lot of power for several days without an outlet, this new product is not it – opt for a classic 20,000mAh power bank. Anyone who wants the highest charging power for a laptop will hit the 20 W ceiling, which is not enough for more demanding devices. And if you have a lot of accessories with a USB-A connector, be aware that there are only USB-C outputs here. Under these conditions, it makes sense to choose a different model.

Verdict: who it’s worth it for

If you’re annoyed by constantly carrying and searching for a cable and want a compact power bank for topping up energy during the day, the AlzaPower Glide for 699 Kč is a cleverly designed new product – the integrated 65 cm retractable cable is precisely the small detail that makes a big difference in practice. However, take seriously that 10,000 mAh is for one to two charges and that the 20 W output is aimed at phones, not laptops. For those who appreciate the convenience of “cable always with you” and a clear display, this is a well-executed piece with a three-year warranty. Those primarily concerned with endurance or power will find more suitable models elsewhere.

Would a power bank with an integrated cable appeal to you, or would you prefer the largest possible capacity?
