Because the Apple Watch can only be charged with the magnetic charging puck, a lot of Apple Watch wearers find themselves bringing the two-meter-long charging cable whenever they travel.
Thankfully, the Amber Watchcase Power Bank by ClearGrass ($99, available on Amazon) offers a stylish solution. This portable battery has enough juice to recharge the Apple Watch up to seven times, and it’s smart enough to stop charging once the Watch is at 100 percent. In addition to a microUSB port for charging the internal battery, Amber has an extra USB port so you can also use it to charge your iPhone simultaneously.
Amber is made from anodized aluminum and plastic, and comes in four colors to match your Watch (silver, gold, rose gold, and space gray).
