The Anker 621 Magnetic Battery is ideal for commuting, travel, and everyday use. Its slim, lightweight design snaps securely onto compatible iPhones for convenient wireless charging while easily fitting into a pocket, purse, or bag.

Charging and fit

• 5,000mAh capacity with magnetic wireless charging up to 7.5W.
• The USB-C port can recharge the battery or provide wired charging to another device.
• Use with a compatible iPhone without a case or with a magnetic case. Non-magnetic cases and metal attachments can interfere with charging.
• Charges one device at a time; a wired connection takes priority over wireless charging.
• Anker does not recommend this model for iPhone 12 mini or 13 mini because of its size.
