Popular Xiaomi power bank with 20,000 mAh discounted in Czechia! It costs just over 4 hundred

If you’re looking for a reliable power bank with a large capacity, you might be interested in the current discount on the Xiaomi Redmi 18W Fast Charge. From the usual 599 crowns, it has dropped to 447 crowns, which is a quarter reduction. According to Heureka, this is the lowest price in recent months.

What do you actually get for that money?

The Xiaomi Redmi power bank offers a capacity of 20,000 mAh, which in practice means approximately four full charges for an average phone. The actual usable capacity is, of course, lower due to losses during voltage conversion; rather, count on three charges plus a reserve for headphones or smartwatches.

The power bank has two USB-A outputs, so you can charge two devices simultaneously. When charging one device, you get a maximum of 18W power (Quick Charge 3.0); when charging two devices, the power is split to 5.1 V at 3.6 A total.

Smart feature for small electronics

An interesting feature is the slow charging mode, which you activate by double-clicking the button. It’s useful for charging headphones, fitness trackers, or smartwatches – devices that are not designed for fast charging and could overheat or get damaged. It’s a detail that competitors in this price category often lack.

You can charge the power bank itself via microUSB or USB-C; both inputs support 18W charging. A full charge of the power bank takes approximately 6-7 hours with a suitable adapter. LED indicators on the power bank body show the remaining capacity in 25 percent increments.

What to watch out for?

With a weight of 420 grams, this power bank is not the lightest on the market. For comparison – modern 10,000mAh power banks weigh around 200 grams. If you’re looking for something pocket-friendly for everyday carry, a smaller variant might be more suitable.

Is the current discount worth it?

If you’re looking for something more modern with a fast USB-C output, you’ll have to dig deeper into your pocket.

The Xiaomi Redmi 18W Fast Charge is not the most modern power bank on the market, but for under 450 crowns, it offers a decent price-to-performance ratio. If you don’t need the latest technologies and prefer a classic that simply works, it’s a reasonable purchase.
