A slim magnetic charger for iPhone and Apple Watch users who want several charging options in one travel-friendly battery pack.
- 0.5-inch ultra-thin body with 10,000mAh capacity.
- Supports MagSafe charging and Apple Watch charging.
- Built-in USB-C cable supports 20W fast charging; a separate USB-C port connects to external devices.
- Wireless output reaches a maximum of 15W, with iPhone MagSafe at 7.5W and Apple Watch at 2.5W.
Pros
- Combines MagSafe, Apple Watch, and wired charging options in one pack.
- The 0.5-inch body prioritizes a slim carry profile.
Consider before buying
- Charging slows after 75% battery level.
- Running wired and wireless charging at the same time reduces overall speed, so that mode fits overnight charging better than a quick top-up.
Read the full review summary
CardMag combines MagSafe charging, Apple Watch support, a built-in USB-C cable, and a USB-C port in a 0.5-inch-thin body.
That range suits travel or daily carry when you want a single pack for magnetic phone charging, watch charging, and wired top-ups.
The appeal is flexibility rather than a single charging route: magnetic wireless output reaches a maximum of 15W, while the built-in cable supports 20W fast charging.
Charging slows after the battery reaches 75%, and using wired and wireless charging together reduces overall speed, so simultaneous charging is better suited to overnight use.
The buying factors
LISEN CardMag Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Charging flexibility
MagSafe, Apple Watch charging, a built-in USB-C cable, and a separate USB-C port give the pack several ways to serve compatible devices.
Carry profile
Its 0.5-inch ultra-thin design makes it a compelling choice when a slim profile matters in a bag or pocket.
Wired output
The built-in USB-C cable supports 20W fast charging for compatible devices.
Wireless output
Wireless output reaches a maximum of 15W, with iPhone MagSafe output at 7.5W and Apple Watch output at 2.5W.
Device compatibility
Compatibility covers iPhone 12–17 series and Apple Watch Ultra 2, Ultra, and S11–S3 series; the built-in cable also serves Samsung Galaxy and other Android devices.
Charging while multitasking
Using wired and wireless charging at once reduces speed, making that mode a better fit for overnight charging than time-sensitive top-ups.
Charge monitoring
A digital display shows remaining power and charging status, which helps you judge when the pack needs attention.

Who Should Buy LISEN CardMag?
Good fit
Choose CardMag if you want a slim pack that handles magnetic iPhone charging, Apple Watch charging, and wired power for USB-C devices. The 10,000mAh capacity and multi-device design suit daily carry or travel.
It is a good fit for buyers who value a built-in cable and want to check remaining power at a glance. Confirm that your phone case supports MagSafe before depending on magnetic charging.
Who should skip it
Look elsewhere if your priority is the quickest possible multi-device top-up: using wired and wireless charging together reduces overall speed, and charging slows after 75%.
If you use a non-MagSafe case, magnetic charging may cause heating; consider a different charging setup or confirm case compatibility first.
LISEN CardMag: slim design with flexible charging
A slim, multi-route charger
The 0.5-inch body keeps CardMag focused on portability, while MagSafe, Apple Watch charging, an embedded USB-C cable, and a USB-C port broaden its use across compatible devices.
The digital display adds a quick way to check remaining power and charging status.
Output depends on the charging route
The built-in cable supports 20W fast charging, while wireless output reaches a maximum of 15W. iPhone MagSafe output is 7.5W and Apple Watch output is 2.5W, so buyers should match expectations to the device and charging method.
A compromise for simultaneous charging
Charging a device by wire while using wireless charging reduces overall speed, and that combination is best suited to overnight use.
Charging also slows beyond 75% battery level, a practical consideration if you tend to top up devices close to full.

Its 10,000mAh capacity, built-in cable, and digital display make it a versatile daily or travel companion.
