A slim magnetic charger for iPhone and Apple Watch users who want wireless charging plus a built-in USB-C cable for other devices.
- 10,000mAh capacity for daily and travel use.
- 0.5-inch ultra-slim body with MagSafe and Apple Watch charging.
- Built-in USB-C cable supports 20W fast charging; a separate USB-C port connects external devices.

Pros
- Slim 0.5-inch body suits buyers prioritizing a compact magnetic charger.
- Combines MagSafe, Apple Watch and USB-C cable charging.
Consider before buying
- Wireless output varies by device: iPhone MagSafe is 7.5W and Apple Watch is 2.5W, below the stated 15W maximum.
- Charging slows beyond 75%, and using wired and wireless charging together reduces overall speed, making that combination better suited to overnight charging.
Read the full review summary
The CardMag combines a 0.5-inch body with MagSafe charging, Apple Watch charging, a built-in USB-C cable and a USB-C port. That gives compatible-device owners several ways to top up without packing a separate cable for USB-C charging.
Its strongest fit is someone carrying a MagSafe-compatible iPhone and Apple Watch who values a slim magnetic pack and an integrated cable.
The 10,000mAh capacity supports daily and travel use, though charging speed varies by method and slows after the phone reaches 75%.

Who Should Buy LISEN CardMag?
Good fit
Choose the CardMag if you carry an iPhone and Apple Watch and want one pack that handles magnetic phone charging, watch charging and USB-C devices.
Its 0.5-inch body and built-in cable focus on keeping the charging setup slim and straightforward.
It also suits travelers who want 10,000mAh capacity and a quick way to check remaining power. The display, multiple charging routes and cable storage give the pack practical utility across a day away from an outlet.
Who should skip it
Skip it if your everyday case is not MagSafe-compatible and you expect to use magnetic wireless charging; the product notes that such cases may cause heating.
Look elsewhere if you need faster wireless charging on an iPhone: the iPhone MagSafe output is 7.5W, while the 15W figure is the maximum across supported wireless charging modes.
LISEN CardMag Charging and Carry Tradeoffs
Magnetic charging and case fit
MagSafe charging makes the CardMag most natural for compatible iPhones. Check that your case supports MagSafe before relying on the magnetic connection, since non-MagSafe cases may cause heating.
One pack, several device paths
The combination of Apple Watch charging, a built-in USB-C cable and a USB-C port gives the pack range beyond magnetic phone charging. That flexibility is useful when your carry includes both Apple gear and USB-C devices.
Output depends on the route
Wired USB-C reaches 20W, while wireless output is capped at 15W and varies by device. For iPhone MagSafe, the stated 7.5W output is the more relevant figure; charging also slows after 75%.
Using multiple outputs
The pack can charge through wired and wireless routes at the same time, but overall speed drops in that mode. Treat simultaneous charging as a convenience for overnight top-ups, rather than the fastest way to restore power.
