The phone charges even without a cable. Choetech magnetic power bank is now very cheap

When you’re using navigation or taking photos outdoors, you don’t want to also keep an eye on a cable between your phone and power bank. The Choetech B822 magnetically attaches to a compatible phone or case and wirelessly recharges it. It has a capacity of 10,000 mAh and now costs 664 CZK with code ALZADNY30 on Alza. It’s particularly interesting for everyday carry, where convenience is valued more than a huge power reserve in a backpack.

Quick summary:
✅ Makes sense: as a backup for your phone for a full day out, if you don’t want to deal with a cable while charging.
⚠️ Consider: the phone must support wireless charging; for attachment, it needs compatible magnets in the body or case.
💡 Via USB-C, it can deliver up to 20 W. Wireless 15 W is the maximum, not the guaranteed speed for every phone.

Magnets for convenience, USB-C for faster charging

Magnetic attachment has a practical advantage: you don’t have to hold your phone and power bank as two separate items while moving. Choetech states MagSafe compatibility; for phones without their own magnets, a suitable magnetic case for wireless charging can be used.

The power bank weighs 181 g and is 17 mm thick, so the phone will feel noticeably heavier in hand with it attached. If you’re in a hurry, you can opt for a USB-C cable and use Power Delivery charging up to 20 W. The power bank itself is also recharged via the same connector, accepting up to 18 W input. According to the manufacturer, it contains a semi-solid battery.

Without the code, Alza prices this model at 949 CZK. By entering ALZADNY30, you reduce it to 664 CZK.
