I picked up the UGREEN MagFlow Air Magnetic Power Bank for travel, and the 5000mAh capacity is just right for a quick top-up on my phone. The magnetic attachment holds firmly and the Qi2 15W wireless charging keeps things neat without cables. It's slim enough to slip into a pocket, though 5000mAh won't fully recharge a large phone multiple times. For daily carry and short trips, it works exactly as expected. Solid build and easy to use.
