Sharge is getting ready to launch its newest high-output portable charger, the Shargeek 300 power bank, through a Kickstarter crowdfunding campaign starting February 10. The company has been teasing this “next gen power beast” since May 2025, and earlier sign-ups were offered the chance to grab an early bird deal in December.
The big headline feature is right in the name: Shargeek 300 delivers up to 300W of combined output, positioning it as a serious option for people who want a travel-friendly power bank that can handle laptops, tablets, phones, and accessories without constantly juggling cables. It includes two USB-C ports that can deliver up to 140W, making it possible to charge two USB-C laptops at the same time (depending on each device’s charging requirements). There’s also a USB-A port for older cables and accessories, plus a 140W DC output. Fast-charging support is covered too, with PD 3.1 compatibility aimed at modern high-wattage devices.
Despite its high power output, Sharge is marketing the Shargeek 300 as airline-safe thanks to its 24,000mAh battery capacity (86.4Wh). When it’s time to refill the battery, it supports up to 140W input charging to reduce downtime. On the outside, an integrated smart display keeps things clear by showing remaining battery level along with other charging details, so you can quickly check what’s happening without guessing. Sharge also adds customizable RGB lighting effects for users who like a more expressive, gadget-forward look.
Design-wise, the Shargeek 300 is built with an aluminum body and two transparent sections. One of those sections is used to showcase the display, matching the brand’s signature techy, see-through aesthetic.
As for pricing, Sharge says Kickstarter pledges are expected to start at $149, though the final retail price hasn’t been confirmed yet. For comparison, the older Shargeek 170 power bank, which also has a 24,000mAh capacity but tops out at 170W total output, has been sold at a higher regular retail price point.
