Keeping mobile phones charged is rapidly becoming just as profitable as making the smartphones themselves. As such, we're seeing all kinds of power banks hitting the market. We saw the Fuel charger hit Kickstarter earlier this month, which claimed to be the world's smallest battery back-up, and now a company called Powerocks is entering the fray with Tarot, which it claims is "the world's thinnest power bank."
The obvious selling point of the Tarot is its size. It comes in at 3.5 inches tall, 2.1 inches wide and 0.28 of an inch deep, or 89 x 53 x 7 millimeters. This means the height and width are about the same size as a credit card, so the Tarot could conceivably be carried around in a wallet. The aforementioned Fuel charger, which is quite a bit smaller in terms of height and width, has a depth of half an inch, so Tarot definitely wins out in that regard.
The 1,500 mAh battery contained within the Tarot is actually quite powerful when you consider the size of the device. For most smartphones, this will be enough to grant one full charge, but some of the more power-demanding devices may see a little less. Still, for a device that fits in a wallet, that's not a bad deal.
Like most battery back-ups, it includes a standard USB port, so it can charge most smartphones, tablets, Bluetooth devices, and so on. The device includes four LEDs, which keep the user informed in regards to how much battery life remains within the Tarot. Of course, it also includes a USB port for the device itself to be charged.
Powerocks's Tarot is available now for US$34.99 from its website. It is also available from Amazon for the same price.
