SmartCoby Ultra Slim SS5K pairs a semi-solid battery cell with a stainless steel shell, making it one of the thinnest 5,000mAh wireless power banks in its category. It is built with NovaCore C3, a battery health and cycle tracking system rated for 300 charge cycles. The power bank offers wireless charging up to 15W for EPP compatible Android phones and 7.5W for iPhone 12 through the newest models, plus a USB-C port delivering up to 20W wired.
At 6.83mm, SmartCoby Ultra Slim SS5K is thinner than nearly every iPhone on the market, including the iPhone 17 Air, fitting easily into a pocket or laptop sleeve. Full pass through charging lets it stay plugged in overnight with a phone attached, charging both without extra wear on the power bank’s own battery, a setup suited to travel and nightstand use alike.
SmartCoby Ultra Slim SS5K follows SmartCoby Ultra Slim 3K, CIO’s MagSafe compatible power bank that funded on Makuake at 10,192 percent of its goal, raising roughly $200,000 from 3,856 backers, then added a second Kickstarter campaign that raised roughly $16,000 more from 267 backers. Ultra Slim 3K is now available on Amazon for $73.99 and remains part of CIO’s current SmartCoby lineup.
Backers can pledge starting at $45.74 for SmartCoby Ultra Slim SS5K, with an estimated ship date of December 2026. The campaign runs through October 28 on Kickstarter. Final specifications, weight, and pricing remain preliminary and subject to change ahead of fulfillment.
