Shargeek 300 launches as new high-capacity power bank with 300W fast charging support

Shargeek introduced the Sharge 300 as the "world's first" power bank that has combined 300W fast charging support and a DC output port. It was previewed in late May 2025, and now, the portable charger has made its much-awaited Kickstarter launch.

The 300W power bank can currently be scored by backing it up on Kickstarter. Among all the packages available, the one with only the Sharge 300 currently costs $149, which is an early-bird price. This price will be available for the first 1,000 pledges, and the company plans to deliver these orders in May 2026. After the early bird offer ends, it will cost $159 throughout the Kickstarter backing period.

Getting back to the power bank itself, it has a four-port configuration, with two of them being USB Type-C ports. Among the other two, one is a USB Type-A port, and the other is a DC in/out, which is one of the standout features of the Sharge 300. The total power output rating is 300W, and each of the USB-C ports maxes out at 140W.

As for the DC port, it can offer adjustable power output, ranging from 25W to 140W. The power bank can also be recharged quickly, thanks to the 140W self-charging speed (Ugreen Nexode 200W charger curr. $59.99 on Amazon). Shargeek further highlights that the rated capacity is 24,000mAh, and it's marked as airline-safe as well.

Regarding the design, the Sharge 300 has a transparent panel on the front, matching the aesthetics of some of the other products that the brand offers. There's an RGB strip surrounding the panel, and Shargeek says that the lights are customizable. The front also has a display that can show more than just the core charging status.
