Portable Power for Apple Watch

The 2-Power D3 is a 2500 mAh magnetic charger built for Apple Watch Series 2 through 11, SE 1 through 3 and Ultra 1 through 3. It supplies 2.5 W of wireless power and stores enough energy for up to four full charges of the smaller models or two of the Ultra. A built-in USB-C cable and metal keychain make it a self-contained travel accessory.

Fits a Minimal Carry

No separate cable or wall adapter is required because the USB-C lead is integrated into the 3×1.9×0.7 inch body. The keychain loop attaches to a bag or keys, freeing the user from hunting for outlets on RV trips, camping, or daily commutes. Recharging the power bank itself takes a 20 V, 3.42 A source delivering up to 85 W.

Capacity and Limits

The 2500 mAh cell delivers roughly one to three hours per watch charge depending on model. It covers multiple days for Series and SE wearers but only one to two cycles for Ultra owners. Builders who need more storage for additional devices or repeated Ultra top-ups will need a larger power bank.

Questions about this item

How many full Apple Watch charges does the 2500mAh battery deliver before it needs recharging itself?

The 2500mAh capacity provides up to four full charges for Apple Watch SE 1-3 or Series 2-11, and up to two full charges for Apple Watch Ultra 1-3.

Does the charger become hot or noisy during extended daily use?

The advanced multi-protection chip prevents overheating while charging your watch and offers overvoltage, overcurrent and short-circuit protection when recharging the charger itself for stable, safe operation.

Which port and cable are required to recharge the power bank between uses?

A built-in USB Type C cable is included, so you only need a USB-C power source such as a laptop, wall adapter or car charger to replenish the 2500mAh battery.
