That said, a little heat during charging is normal, but it’s something to keep in mind if you’re using it for extended periods. Also, the magnetic hold is phenomenal, but I’d be cautious if you tend to toss your phone around a lot.

Still, for daily use, this little power bank packs a serious punch.

Wireless charging maxes out at 7.5W, so it’s a bit slower than wired at full speed. Still, the overall convenience makes up for it, especially for quick top-ups during busy days.
