Catmart V12 Magnetic Power Bank, 10,000mAh, 20W USB-C and 15W Wireless Charging

For iPhone users who want a portable power bank that attaches magnetically for wireless charging, the Catmart V12 combines a 10,000mAh capacity with a compact, card-sized design. Its magnetic connection keeps the charger aligned with compatible phones, while USB-C provides a wired option when you want to charge that way.

At home, on a commute, or while traveling, you can choose between 15W wireless charging and up to 20W wired charging. The V12 can also charge two devices at once, making it useful when a friend or family member needs power too.

Practical tips

For magnetic wireless charging, use a MagSafe-compatible iPhone or another phone that supports magnetic wireless charging. The product is listed as compatible with iPhone 12 through iPhone 18 series and most Android devices, magnetic charging depends on the phone’s wireless-charging support. If you prefer a cable, connect through USB-C for wired charging at up to 20W.

You can recharge the power bank through USB-C while it wirelessly charges another device, a passthrough option that helps simplify charging when you have access to a power source. When charging two devices at the same time, the unit may become warm, which the product information describes as normal. For a day out, its portable format lets you carry backup power without relying on a wall outlet throughout the day.

What stands out

The 10,000mAh capacity gives you a substantial reserve for a phone, while the choice of wireless or wired charging lets you adapt to the situation. Magnetic attachment is particularly convenient when you want to keep using your phone without managing a separate cable. A USB-C wired connection is also available, and the V12 supports simultaneous charging for two devices.

The design pairs a Grade 5 titanium alloy exterior with a soft-touch silicone panel. The micro-sandblasted finish gives the gray charger a refined look, while the panel is intended to help protect the phone and charger from scratches. Its compact, card-sized profile is made for carrying in a pocket or bag, whether the day involves travel, work, or time outdoors.

Worth noting

Buyers often highlight the magnetic connection and portability, and some say the charger works through their phone case. Feedback on its weight and slim feel is mixed: some appreciate the compact design, while others find it heavier or less thin than expected. These impressions can help set expectations for carrying it daily, alongside its practical combination of magnetic wireless and USB-C charging.

Catmart also provides 18 months of after-sales service. The charging options, magnetic attachment, and portable capacity make the V12 a flexible alternative to a basic wired-only power bank, especially when cable-free phone use matters.

Final verdict

The Catmart V12 is a practical fit for users who want 10,000mAh of backup power in a magnetic charger that also supports USB-C. Choose it for compatible phones when easy attachment and wireless charging are priorities, or use its wired connection when that better suits the moment.
