With the Anker Nano Power Bank (5K, MagGo, Slim), thin is definitely in. Measuring just 0.34 inches deep, the Qi2 power bank attaches magnetically to MagSafe iPhones and delivers enough juice to get you through a frantic afternoon on the go.
At just 5,000 mAh, it won’t take modern iPhone batteries all the way to 100%. But it will power up a dead iPhone from zero to 20% in a little over 20 minutes. And it does so while attached comfortably to the phone, without the excessive heat generated by some competing power banks.
