When you need a reliable power bank for a reasonable price, this offer from Lidl is worth considering. The TRONIC 10,000 mAh power bank is currently available for 270 Kč instead of the original 300 Kč. For this price, you get solid features including fast charging and the ability to charge two devices at once.

What the power bank can do

The TRONIC model has a 10,000mAh capacity, which in practice means approximately 2-3 full charges of a typical smartphone. You have two USB-A outputs and one USB-C port with Power Delivery, so you can charge a phone and, for example, headphones simultaneously. The maximum power is 15 W when charging two devices, and up to 18 W individually.

It also features an LED charge status indicator, although a display with percentages would be slightly more practical. The power bank itself charges in approximately 6.5 hours via the USB-C port. The package also includes a short USB-A to USB-C charging cable with a length of 15 cm.

The clear weakness is power

Although the power bank theoretically supports Power Delivery 3.0 and Quick Charge 3.0, the reality is more modest. Individual ports can handle a maximum of 12 V at 1.5 A, which corresponds to 18 W of power. In 2025, this is more of a basic standard than fast charging. When charging two devices simultaneously, the power even drops to just 15 W total – meaning approximately 7.5 W per device.

Protection is provided by a system against overheating and short circuits. Its dimensions of 13.2 × 6.8 × 1.6 cm make it a relatively compact piece that fits into a pocket or handbag.

Price: 270 Kč

Who it’s suitable for

For 270 crowns, you get a decent power bank for everyday use. If you’re looking for a backup power source for occasional phone charging during the day or for a weekend trip, this is a reasonable choice. The TRONIC model will especially appeal to those who don’t want to spend hundreds more on premium models and only charge away from home out of necessity.

On the other hand, if you travel frequently or need to charge more demanding devices like tablets, you might appreciate more powerful alternatives. Also, if you prefer well-known brands with a longer tradition, you’ll find interesting models from competitors as well.
