The UGREEN MagFlow Magnetic Wireless Power Bank 10000mAh Qi2 25W sticks firmly to my phone and charges without cables, which is exactly what I wanted for travel days. The 10000mAh capacity gives me a couple of top-ups before I need to recharge it, and Qi2 25W is quick enough to be useful rather than just a trickle. It is a bit chunky in a pocket, so I mostly keep it in a bag. Build feels solid and the magnets hold well even when I pick up the phone.
