Alza started selling a gigantic 50,000mAh power bank with super charging power. It costs less than 1,500 CZK

ChoeTech has expanded its range of high-capacity power banks. Following the recently introduced 22.5W model, which we wrote about, Alza has now started selling the more powerful ChoeTech PD65W with a 50,000 mAh capacity and 65W output for 1,399 CZK. The main difference compared to its weaker sibling is precisely the power: 65 W is enough to charge a laptop. So, if how quickly devices charge is important to you in addition to capacity, this might interest you.

Quick summary:
✅ It makes sense if you want a large power reserve that, thanks to 65 W, can charge a laptop or quickly recharge a phone.
⚠️ Consider that due to its 185 Wh capacity, you cannot take it on an airplane, and with a weight of 1100 g, you’ll carry it in a backpack, not a pocket.
💡 For 1,399 CZK, it offers both 50,000 mAh and 65 W, significantly more power than the cheaper 22.5W sibling for 899 CZK.

Why this power bank is interesting

ChoeTech has combined a massive 50,000 mAh capacity with 65W output, a combination that hasn’t been common at a reasonable price for a long time. While the weaker 22.5W model primarily served phones and headphones, 65 W can now power a laptop or fully fast-charge modern phones. There are three outputs (2× USB-A and 1× USB-C) and a digital display showing the precise battery status. For 1,399 CZK, it’s an affordable way to have power for all your devices even when away from an outlet.

Key parameters explained simply

The total output of 65 W is distributed among three ports (2× USB-A, 1× USB-C), with a maximum of 4.5 A and 12 V via USB Power Delivery. The capacity of 50,000 mAh (i.e., 185 Wh) is the same as the cheaper model – in reality, you can charge an average phone about 6.5 times, not ten, as simple math might suggest (some energy is lost during voltage conversion). It also features a USB-C input for recharging the power bank itself and a set of protections. The weight is 1100 g.

How it differs from its 22.5W sibling

The main difference of this power bank compared to the cheaper model is its power output. While the 22.5W version for 899 CZK targets phones and small electronics, this 65W variant for 1,399 CZK can also handle a laptop and charge modern flagship phones at their full speed. The capacity, number of ports, and display remain the same, so you’re mainly deciding between a lower price (22.5 W) and higher power (65 W). The power bank recharges via USB-C; due to its large capacity, expect a longer charging time.

What to watch out for

One warning applies equally to both versions: with 185 Wh, the power bank exceeds the 160 Wh limit, so you cannot take it on an airplane – neither in carry-on nor checked luggage (rules are also likely to become stricter in 2026). Also, expect a weight of 1100 g, so it’s a piece for a backpack, not a pocket. The battery has a lifespan of 6 months, like consumable material, although the product warranty is 24 months. And because it’s a new product with minimal reviews so far, there is currently little real long-term experience.

Who it’s for and who it’s not for

The power bank makes sense if you want a large power reserve even for more demanding devices – a laptop on the go, fast phone charging, or multiple devices at once in a cabin or car. However, if you only need to occasionally charge your phone and want to save money, the cheaper 22.5W model will suffice. And if you fly frequently, opt for a smaller power bank under 100 Wh that you can take on board.

Verdict: it’s worth paying extra for power

For 1,399 CZK, the ChoeTech PD65W is an interesting new product for anyone who wants a lot of energy and enough power for a laptop. Compared to its 22.5W sibling for 899 CZK, you pay an extra 500 CZK but gain almost triple the power, which makes sense for a large power bank. The main compromises – weight and the inability to take it on an airplane – stem from its large capacity and apply to both models. For off-grid use where you don’t want to deal with weak charging, it’s a successful piece of equipment.
