Nimble this week debuted the SharePower, a USB-C power bank that can be used as a single charger or split into two chargers so it can be shared with a friend.

SharePower is a 10,000mAh power bank, with 5,000mAh available through each side of the device. The two halves attach together magnetically for charging a single smartphone, or come apart to charge two. We were able to test the SharePower before launch to see how it works.

Each side has an included USB-C cable. The left half has a 7-inch braided cable that doubles as a lanyard and it can tuck into the interior when the two halves are connected and the cable isn't in use. The right half of the power bank has a short pop-out USB-C cable. The side with the pop-out cable is nice because it attaches to the bottom of the iPhone and it's compact in size. The longer cable is useful if you need a bit more length when charging.

In our testing, both modules charged at the advertised speeds, but there was a faint electronic sound when charging, regardless of whether one module was in use or both modules were paired. 5,000mAh isn't enough to charge an iPhone 17 Pro Max to full, but the combined 10,000mAh can do so.

When paired, the two halves deliver up to 35W power to fast charge an iPhone, and when separated, each half offers 20W charging. There are two additional USB-C ports, one on each side, so up to four devices can be charged at one time when the power bank is separated, and three when it's combined. 20W is a little slow because the ‌iPhone 17 Pro‌ models need a higher watt charger to fast charge, but it's nice to have the option for splitting the charger if two people need power at once.

There's an LCD display that lets you know the remaining charge when the two halves come together and when they're separated, and it's a clever design. The left half has indicator lights so you can see the battery level when it's separated, and the right half has a percent reading. When the two halves are reunited, the percent reading changes to the combined total instead of just the battery level of the right half. When your device is fast charging, there's a green PD light.

There are smaller 10,000mAh power banks out there, but the dual design of the SharePower stands out. It measures 2.8 inches by 3.1 inches, and it is an inch thick. It weighs 7.6 ounces, and comes with an extra USB-C cable so you can charge it.

Nimble's SharePower is useful for anyone who has run into a situation where multiple people need to charge their iPhones at one time. With hundreds of power banks on the market, it manages to distinguish itself with added flexibility.

SharePower is available in white, blue, and pink. It can be purchased from the SharePower website or from Apple.com for $80.
