Running out of battery on the road is a nightmare for travelers, and Ampsos is hoping to solve that with its new all-in-one power bank. The company has just launched a Kickstarter for what it calls a “5-in-1 25,000 mAh Laptop-Grade Power Bank Hub with Solar Boost.” It’s a mouthful, but the idea is simple: a compact, flight-friendly battery pack that can keep just about everything charged—laptops included.
This power bank carries a 25,000 mAh capacity (roughly 90 Wh), which makes it airline-safe and easy to slip into a carry-on without raising eyebrows at security. Ampsos says the hub can push out up to 170W total. Three USB-C ports handle the heavy lifting—each capable of 100W—while there’s also a 33W USB-A for older gadgets and even a 3W wireless pad for earbuds. Two of the USB-C ports have built-in cables, which means one less thing to remember when packing.
A small OLED screen shows real-time stats like battery level, charging status, and even solar input. That’s because the bank doesn’t just recharge from the wall (100W input for a full refill in about 90 minutes), but also from the sun. With 36W solar charging (thanks to its integrated MPPT controller), you can top it up outdoors and even power devices while it’s charging.
Size-wise, it’s fairly compact—175 x 55 x 51.6 mm and about 600 g—lighter than many competing high-capacity bricks. Ampsos is pitching it as a versatile travel companion that replaces carrying multiple chargers and cables.
The Kickstarter price starts at $109, with shipping expected in November 2025. As always with crowdfunding, delivery timelines are a question mark, but if Ampsos delivers, this could be one of the more practical solar-powered hubs we’ve seen.
