One complaint heard since the Apple Watch's debut has been its battery life, the smartwatch must be charged every night.

Soon, there will be a band that will charge the Apple Watch as it is worn, providing up to 30 additional hours of use, according to TechRadar.

The Reserve Strap is a band for the Apple Watch that is capable of charging the Apple Watch with a hidden port.

There were concerns that Apple would not approve the use of the hidden port, but the makers of Reserve Strap have been able to confirm with Apple that they it will be approved. Additionally, using the Reserve Strap will not void the AppleCare warranty or Apple Terms & Conditions.

The Reserve Strap will be compatible with both the 38mm and 42mm Apple Watch sizes. It is a waterproof band and it will not interfere with the existing sensors on the Apple Watch.

Users will know how much power is left in the Reserve Strap by looking at the LED light indicators. To recharge both the Reserve Strap and the Apple Watch simultaneously users will use a micro USB cable.

While the Reserve Strap will not be available until Nov. 3, it is already available for purchase from the company's website. It is currently available in three colors: white, grey and black.

The Reserve Strap carries a hefty price tag of $249.99, which is only $100 less than the Apple Watch Sport. However, the additional 30 hours of battery life is about a 167 percent increase on the normal battery life of the Apple Watch.

The Reserve Strap will ship to anyone in the world for a flat $20 shipping charge in November. This is one solution for the battery life complaints that many Apple Watch users have, but it is an expensive solution.
