Compact charging case and power bank for Apple Watch. Allows you to charge your smartwatch directly on your wrist without interrupting workouts or sleep. Provides an extra 15 hours of use, features a strong magnet, 10 safety levels, and raised edges to protect the screen.
Charge your Apple Watch without interrupting activity
A dead Apple Watch during training means no heart rate measurement, no counting of burned calories or steps. No sleep monitoring at night. You remove the watch, lose data continuity, interrupt your activity. Endurance™ fundamentally solves this problem – you charge the smartwatch without taking it off your wrist. The compact case fits directly onto Apple Watch and you continue training, running, walking, or daily activities. Measurements run nonstop, data is collected continuously.
15 hours of extra use on one charge
A full charge of 3mk Endurance™ gives your Apple Watch up to 15 hours of additional use. That's a full day of intense use: morning workout, activity monitoring during the day, sleep tracking at night – all without worrying about running out of battery. An intelligent control light shows the current battery level of the powerbank, so you always know how much power you have left. No guessing – check it. For someone who trains daily and tracks every metric, it’s the difference between complete data and losing it.
Powerbank and charger in one device
In the field, Endurance™ acts as a powerbank – wirelessly charging Apple Watch while in use. At home, you connect the case to a power source replacing a standard charger. Innovative fast charging technology ensures full power – no less than the original charger. You charge the watch and the powerbank simultaneously. One device, many possibilities.
Strong magnet – stable attachment during activity
The strong magnet for wireless charging guarantees a stable connection between Apple Watch and the Endurance™ case. Intense training, fast running, jumping, strength exercises – the smartwatch remains securely mounted in the case. No need to worry about it falling off, losing contact, or interrupting charging. The magnet works natively with the Apple charging system – full compatibility, instant recognition, automatic start of charging without hassle.
10 levels of protection – complete safety

Train more confidently, knowing your smartwatch is protected on all sides.
