A third part accessory for Apple, the wipowerband, has been reportedly designed to double the Apple Watch's battery life with its high-density polymer case that straps on to the device.
According to the Verge, the report is not not backed up by any actual tests with an actual Apple Watch, but only by "estimates."
There will be many more companies offering a charger for the Apple Watch.
The wipowerband can be pre-ordered for 89 dollars for the 38mm case or 99 dollars for the 42mm case.
