Our Take

Minimalist, pocket-friendly, and genuinely helpful for iPhone users on the move.

Anker's MiniCell tech crammed 5,000mAh into a device smaller and lighter than the competition—no compromise on actual power.

At $42.99 you're paying a bit more than a basic power bank, but you're getting premium magnets and deliberate industrial design that justifies the ask.

Who it is forBest for iPhone 12–16 users who commute, travel, or just hate cable salad—and who value pocket space over the longest possible battery.

How We Judged It

What to check before you buy

Size & Portability

4.13 x 2.62 x 0.45 inches

Slim enough to snap flat to your phone's back or tuck into a shallow pocket. The thin profile means it won't bulk up your carry—you'll actually keep it with you instead of leaving it at home.

Magnetic Attachment

Ultra-strong magnets, compatible with iPhone 15, 14, 13, 12 series

The magnets hold firm enough for one-handed selfies and calls without the constant micro-adjustments that plague cheaper wireless chargers. Alignment is instant and reliable.

What's in the Box

5,000mAh battery, 23.6 in USB-C to USB-C cable, 24-month warranty

Cable included means you're charged and ready out of the box. The 24-month coverage takes the risk out of buying a compact power device that'll live in your bag.
