Portable power banks can be a lifesaver if youre on the go and find your phone out of juice, but theyre also bulky and annoying to carry around. The new CarbonBlade from Sharge aims to solve that with an ultra-slim build that makes it much easier to fit in your pocket, even when its in the same pocket as your phone.The power bank measures only 0.46 inches thick, while still offering a relatively large battery. That battery size is 10,000mAh, which makes it large enough to fully charge an iPhone 16 1.7x and a Samsung Galaxy S24 1.5x. According to Sharge, the power bank is 40% thinner than conventional 10,000mAh batteries, and at 165 grams, its lighter, too.Its even built to be eco-friendly as the battery bank is made from recycled carbon fiber. It should be strong enough to last through years of usage without major damage.The recycled carbon fiber design is sleek and makes the battery bank a little more unique than the traditional all-black power banks that most brands offer, and the red highlights of the power button and USB ports help it stand out. Its outfitted with USB-C and a USB-A ports for convenient charging and a power output of up to 22.5W, which is pretty quick for a portable battery like this.The Sharge CarbonBlade retails for $69.90 and is available at sharge.com.
