'Reserve Strap' Plans to Charge the Apple Watch on the Wrist

Following an afternoon of discussion on the recharge rate and battery life of the Apple Watch, third-party developers Lane Musgrave and John Arrow today revealed the "Reserve Strap", which will allow users to charge their Apple Watch while wearing it on their wrist.

The device consists of a silicone band with embedded lithium polymer cells and an inductive charging cradle that will hold the Apple Watch, resulting in a 125 percent battery life increase over the basic life of the Apple Watch, according to the company.

The Reserve Band will charge the Watch "similar to the new MagSafe wall charger for the Apple Watch", thanks to a few batteries embedded within the device using magnetic inductive charging. Musgrave notes that while they "don’t have hard numbers yet", their current testing leaves them to believe their claim to a 125 percent increase in battery is close to the mark.

The case looks slickly designed, especially considering the amount of power the two are saying hides within the silicone band, but perhaps the biggest cause for concern lies in the possibility for obstruction of the Apple Watch's heart rate sensor.

Recent news only underlines the sensor's extreme importance in making contact with a user's skin, but Musgrave remains optimistic that their product will meet all the standard expectations when using the Apple Watch in conjunction with their new device.


Since we haven't been able to test anything on the actual device, it's really hard to say whether we'll be able to prevent interference with the sensors on the back. We won't be able to know for sure until we're able to test on the real thing but it's certainly a priority for our product.
Although it's not yet up and running, a Kickstarter is planned for the Reserve Strap. Those interested in pre-ordering the accessory now can do so for $249.99 from Reserve Strap's official website, though no official release date has been set. Musgrave and Arrow reiterate on their website that the first shipment of bands will be "extremely limited" due to the funding of the nascent project coming entirely out of their own pockets.

A $249 accessory for a $349 watch...

At that price, you might as well buy another watch, and swap them out each day while the other is charging.

$249 is a joke

It's an elegant solution to what is inevitably going to be many people's #1 complaint.

But at $250 this thing is going absolutely nowhere.

This also assumes the watch will function as normal when it's on a charger.

On my Fitbit Surge when it's plugged in the HRM turns off... I have a feeling this thing is just going to be vaporware.

And for that price I could buy a Pebble Time and still have $50 bucks left over to wear when my Apple watch goes dead. :P

This is assuming Apple allows 3rd parties to make straps for the watch.


I can't think of any ways they can stop them, assuming there are no data connections in the strap

As I stated in another thread about this, they better be damn sure they can replicate the frequency and any digital handshake Apple does with the stock inductive charger.

This also, also assumes that the sensors on the back don't need to be in direct contact with the skin.

I know I'm not the first, but I wanted to go with the theme.


I thought direct contact was how it determined it was still on your wrist and would otherwise deactivate to prevent data theft and Apple Pay use.
