This bulky band wants to boost your Apple Watch's battery

If there’s one problem plaguing today’s tech, it’s the battery. Most people carry their chargers around everywhere, and sometimes a powerbank too (if you don’t, you should). It’s impossible to rely on a device, whether it’s a smartwatch or a smartphone, to last more than a day or two.

The Apple Watch is no exception as it almost always requires a daily charge. Battery bands are becoming a staple accessory, and here’s another one to add to the list — the Prime strap. What’s unique about Prime is that it uses the 6-pin port under the metal shield on the bottom of the watch to charge the wearable.

The watch band itself houses two changeable 150mAh batteries on both sides of the band that charge the watch via the 6-pin port. It’s more like you’re placing your Apple Watch into a permanent power bank. Which brings us to the band itself. It looks bulky and is visually unappealing. There’s a stainless steel version and one that’s made of aluminum alloy, which come in two sizes of 38mm or 42mm. They both look like bulkier straps you’d find on old calculator watches.

One Prime battery adds nine hours to the lifespan of the watch, so as the kit includes two, the beefy watch band should extend the battery life by 18 hours. Swapping batteries is pretty simple as all you have to do is tap on the side compartments of the band to open them. Then take the batteries out and pop the new ones in. There’s a color LED light on the strap that displays the status of the battery.

BrilleTark, the makers of this device, launched the Kickstarter recently and has currently made $6,950 of its $30,000 goal.

The company is also offering a Prime Bank, where you can store and recharge your batteries on the go. The batteries take about 2.5 hours to fully charge, and the Bank itself is an all-in-one charger that has a Lighting port so you can charge your phone at the same time. If you don’t want the Bank, the standard kit comes with desktop recharger with a USB charging port and an AC plug.

You’ll also be getting a Prime Toolkit with screws, a screwdriver, and a 6-pin port opener. That’s right, buying the band means you’ll have to put the whole thing together yourself, though it doesn’t look complicated.

And to top it all off is a hefty price tag. The Super Early Bird option lists aluminum alloy variant for $200, and that comes with everything including the Prime Bank. The stainless steel Super Early Bird costs $300. There’s a lot of pricing options to choose from, but it goes all the way up to $380.

It’s a pricey accessory for a bulky watch band, but sometimes the option for a little more juice is worth it.

Victrola’s Stream Onyx turntable makes listening to vinyl over Sonos more affordable
The Victrola Stream Onyx Sonos-ready turntable on a wood cabinet with a Sonos Five.

Time-honored audio gear pioneer Victrola is continuing its foray into the wireless record player market, today unveiling the Victrola Stream Onyx turntable at CES 2023 in Las Vegas. An updated and more affordable continuation of its popular Stream Carbon turntable launched earlier last year, the Works with Sonos-verified player allows vinyl lovers to spin their records and wirelessly stream the audio over their Sonos speaker system via Wi-Fi. The new player will retail for $600 and will be available for preorder on January 7.

While Bluetooth-enabled turntables offer the convenience of being able to wirelessly play your records through headphones and speakers, Bluetooth is not the ideal way to do this, as you can lose a lot of the details and accuracy from the vinyl because of the digital file compression needed. Most people wouldn't notice the difference, but using a higher-fidelity wireless system like Sonos to do this is a much better option (especially for audiophiles), one that Victrola started making a lot easier with the Stream Carbon turntable last year.

What is NFC? Everything you need to know about how it works
NFC settings on an Android phone.

Nearly all of today’s smartphones and smartwatches are equipped with NFC technology. Whether you realize it or not, your phone's NFC scanner is likely active right now. Don’t worry, though, as the NFC chip in your phone is a passive scanner that does nothing until you hold it within a couple of inches of another NFC device or tag. Like many features of your smartphone, it quietly sits in the background until it's needed, but it can also be used to unlock a wide range of cool features that can make your life easier.

If you've ever used Apple Pay, Google Pay, or Samsung Pay, then you've already taken advantage of the NFC feature on your phone. However, NFC can do a lot more than just handle mobile payments.
What is NFC, and how does it work?

Break out the champagne and roll out the red carpets, CES is back! After two rough, COVID-addled years that saw the world’s greatest tech show reduced to a shell of its former self, the show is primed to spring back to its former glory for 2023. And our team of writers and editors will be on the ground in Las Vegas, bringing it all to you.

But much has changed since the last “normal” CES of 2020. The economy has boomed and busted, supply chains have knotted, and attitudes over excess have shifted as climate change looms larger and larger in our global conversation. And as always, the tech itself has marched forward, rising to the challenges of our new post-COVID lives.
