Anker’s MagSafe wireless charger is slim, powerful, and 43% off for Prime Day

In a world where smartphones are a part of our daily routine, there are few things more anxiety-inducing than having a dead battery. Portable battery chargers help fix that problem, but they’re typically bulky, require a cable, and they can be a pain to carry around. The Anker 622 MagSafe Wireless Charger helps fix that problem. It can affix itself onto any MagSafe-compatible iPhone for some easy charging power. These things generally go for around $70 on Amazon, and it’s on sale for $40 for Amazon Prime Big Deal Days.
