Earlier this month, the group behind the battery-boosting “Reserve Strap” for the Apple Watch recommended it was possible to use the covert 6-pin diagnostic port in the Apple Watch to charge the device, and today they have actually supported their claims with a video presentation.

In the video, an Apple Watch charging on a basic inductive charger is portrayed beside one stated to be charged through a power supply linked to the 6-pin port on the device. The watch being charged through the port charges somewhat faster than the watch on an inductive battery charger, reaching a 95 percent charge at the very same point the other watch reaches a 90 percent charge.

The group behind the Reserve Strap for the Apple Watch prepares to use the port to develop a band with a backup battery within, allowing the Apple Watch to be charged while it’s on the wrist. The product is still in the early phases of development, but it’s offered for pre-order for $$ 250 from the company’s web site.

The Reserve Strap is not currently accredited under Apple’s just recently released accessory program for the Apple Watch, which will allow makers and accessory makers to develop approved third-party bands for the device. Apple has described a certain set of rules for Apple Watch bands, avoiding them from blocking any sensors on the device, however its standards do not point out bands that access the 6-pin port. Because of that, Apple’s position on Reserve Strap’s use of the 6-pin port is unclear.

Apple has not confirmed what purpose the 6-pin port serves, but speculation has actually suggested it is made use of by the company for diagnostic functions. Apple might also be using the port inside for charging, as detailed in documents covering the function of its in-store Apple Watch displays.

It is not known if Apple has strategies to broaden the use of the 6-pin port in the future, however TechCrunch has actually assumed that the port might become made use of for “clever band” accessories to bring extra capability to the Apple Watch.
