Magnetic hold is rock solid, so I can slap it on the back of my phone and toss it in my bag without worrying about it sliding off. Battery life keeps my phone topped up through a full day of heavy use, which is exactly what I needed.

This thing has been a lifesaver on my long commutes—the magnetic attachment is super strong, so it stays put in my bag until I need it. I’ve gone from panicking at 15% battery to finishing my day with juice to spare, and it charges my phone surprisingly fast for a pack this size.
