💡 For 543 Kč, you get both a power bank and a GaN charger together, which is cheaper than buying both separately.

Why this set is interesting

This set from AlzaPower is a nice compact kit for travelers looking for small and lightweight accessories for their trips. In one package, you get a Loop 5000 mAh power bank with an integrated magnetic USB-C cable and a small Apex G400 GaN charger with 20 W output, which allows you to charge your phone and the power bank itself from an outlet. The whole thing weighs around 110 grams and fits in your pocket, so you can take your charging gear in your carry-on without worrying about space or weight.

Key parameters explained simply

The power bank has a capacity of 5,000 mAh (18 Wh) with fast charging support and an integrated USB-C cable as well as a separate USB-C output, so you can charge your phone, watch, and tablet. The charger uses modern GaN technology, which makes it smaller than conventional adapters at the same power output, and supports Power Delivery 3.0 with up to 20 W of power. Both devices support a range of fast charging standards (USB PD, Quick Charge, Samsung, and Apple), so they can handle most phones. The set also offers a Pass Through function, where you charge the power bank and your phone simultaneously through it, plus a three-year warranty.

Why it pays off to buy the set instead of individual items

The main argument for this set is the price compared to buying both items separately. Individually, the charger costs 299 Kč and the power bank 449 Kč, totaling 748 Kč, whereas you can get the set with code ALZADNY20 for 543 Kč – saving over two hundred crowns. It’s fair to add that the charger itself is often on sale and was last discounted to 199 Kč. However, even if you bought such a discounted adapter separately for the power bank (199 + 449 = 648 Kč), the set for 543 Kč is still significantly more worthwhile. So, if you want both, the set is clearly the cheaper option.

What to watch out for

It’s good to have realistic expectations regarding capacity. A 5,000 mAh power bank will realistically charge a phone roughly once – the stated capacity applies to 3.6 V cells, so after conversion to 5 V and accounting for losses, you’ll get less from it. It’s therefore for a backup charge for the day, not a large energy reserve. Also, note that the integrated cable measures only 15 cm (practical, but short) and that 20 W of power is sufficient for phones, tablets, and watches, but not for powering a laptop. On the other hand, a big plus for travelers: thanks to its 18 Wh capacity, the power bank passes through airport security without issues.

When it doesn’t make sense

If you need a large energy reserve for multiple charges or for powering a laptop, this set is not for you – opt for a power bank with higher capacity and power output. It also won’t suit people who already have a quality GaN charger at home and would only want the power bank, or vice versa. And those looking for a long cable or wireless charging won’t find it here. However, as a compact travel kit for charging phones and small electronics for 543 Kč, it makes sense and is cheaper than buying both separately.

Verdict: who it’s worth it for

The AlzaPower Compact Explorer is a handy compact kit for travelers – a small power bank with an integrated cable and a lightweight GaN charger will cover charging for phones, watches, and tablets on the go and fit in a pocket. It’s important to note that 5,000 mAh is enough for roughly one phone charge, and 20 W of power is not for a laptop. At 543 Kč with code ALZADNY20 instead of 679 Kč, and especially cheaper than buying the power bank and charger separately, it’s a good buy for anyone who wants their travel charging gear all in one place.
