The Uvolt is a very clever watch that doubles as a spare battery pack


As for the power reserve itself, Uvolt has four options, with a choice of either an integrated Lightning, USB-C, or MicroUSB cable, or one with wireless charging (although the wirelessly charging reserve will still need to be removed from the watch to function.) Each reserve offers 600mAh of extra battery — not enough to fully charge basically any smartphone, but good enough for a few extra hours on the go. 

The UVolt also has a few clever tricks up its sleeve to extend that time, though. The bracelet links of the watch each contain their own miniature power packs that can together fully recharge the battery reserve once its been drained, doubling the amount of power you can carry. Additionally, the entire face of the watch is actually a solar panel that slowly recharges the batteries in both the power pack and band whenever there’s light available — according to Uvolt, the reserve can reach a full charge over the course of one sunny day.
The watch itself charges through a wireless charging pad that comes with the device, although Uvolt hasn’t specified yet whether its charger is a proprietary system or a more common wireless charging standard like Qi.
Now, the caveats: first and foremost, Uvolt is a first-time company that’s never shipped a product before, which is always worth considering when backing a Kickstarter — especially a hardware one, which tend to have the highest likelihood of failing to deliver the promised product. While the company is selling a version of its battery pack with an integrated Lightning cable, Uvolt doesn’t seem to have Apple’s MFi blessing, a certification which is usually nice to see when buying anything that charges your very expensive smartphone. And there’s no getting around the fact that while the Uvolt is a genuinely interesting idea with a lot of smart, thoughtful touches, it’s not a great-looking watch when it comes to fashion or style.

That said, as someone who both loves weird gadgets and is increasingly tired of traditional smartwatches, I do like the concept of the Uvolt. The Uvolt is available to back on Kickstarter for a range of early-bird prices between $119 and $139, depending on when you back, with the company hoping to deliver finished devices by December later this year or January 2018.
