The MagFlow Magnetic Wireless Power Bank 20000mAh Qi 25W has become my go-to for travel days. The magnets snap on firmly and keep my phone aligned, so I can keep using it while it charges. 25W wireless output is quick enough for top-ups between meetings, and the 20000mAh capacity easily covers a full day plus a second device. It is a bit chunky in a pocket, but that is expected for this capacity. Build feels solid and the finish resists fingerprints well.
