This tiny Anker power bank becomes part of your phone, now discounted to a minimum

Power banks with an integrated connector that attach directly to the phone’s charging port have been gaining popularity recently. You might know a similar principle from photo grips for flagship camera phones. One of the most popular models in this category is the Anker Nano Power Bank 5000mAh, which has now dropped to a historically low price of 447 CZK on Alza after entering the code ALZADNY30. The original price was 790 CZK.

Compact Dimensions and Practical Foldable Connector

The main advantage of the Anker Nano Power Bank is its foldable USB-C connector, which allows you to easily connect the power bank to your phone or tablet without needing to carry cables. The entire construction weighs only 100 grams, and its dimensions of 35.6 × 76.2 × 25.4 mm ensure it fits practically anywhere – in a pocket, handbag, or small backpack.

While the 5,000 mAh capacity isn’t astounding, it’s more than sufficient for a single phone charge on the go. Most users report that the power bank can replenish 50–65% of a typical smartphone’s battery. The 22.5 W charging power ensures relatively fast energy replenishment – although users realistically report values closer to 15 W.

Two Outputs and Pass-Through Charging

The Anker Nano Power Bank features two USB-C outputs – an integrated foldable connector and a classic port on the side. This allows you to charge two devices simultaneously. An interesting feature is Pass Through Charging, which allows the power bank to be recharged while simultaneously powering a connected device. This finds practical use, for example, when working at a desk, where you want to keep both your phone and power bank constantly charged.

The power bank itself charges via the USB-C port with a maximum current of 3 A. A short 60cm USB-C cable is also included in the package.

What Users Say

The power bank has a rating of 4.7 out of 5 stars from 56 customers on Alza, with 89% of them recommending it. The return rate is only 0.87%, which indicates solid build quality.

Among the most frequently praised features are its compact dimensions, low weight, and charging speed. Users appreciate that they “don’t even feel it in their backpack” and that it serves as a reliable backup for trips or evening outings in the city. Some also successfully use it to power GoPro or DJI action cameras during longer shoots.

On the other hand, there are reservations about the durability of the foldable connector. One user reported damage when carrying it in a crossbody bag. Others point out that the power bank’s surface scratches easily. The smaller capacity is a logical compromise for its compact dimensions – anyone who needs to charge their phone multiple times a day should opt for a model with 10,000 mAh or more.

Is It Worth It?

For 447 CZK, you get a quality power bank from the renowned Anker brand, which is suitable as an emergency pocket backup. It’s not a solution for multi-day trips without access to electricity, but for common daily situations – when you need to top up energy on your way home from work or during an afternoon in the city – it’s one of the most practical choices on the market.
