NOBIS N2901 20000mAh 90W power bank

20000 mAh 90 W laptop power bank

The NOBIS N2901 is a 20000 mAh lithium-polymer power bank that delivers up to 90 W from its USB-C port, enough to charge most USB-C laptops while you work. It targets professionals, students and travellers who need multi-day power for laptops, tablets, phones and handheld consoles without relying on wall outlets.

Two USB-C and two USB-A ports with smart

The unit measures 13.7 in x 7.0 in x 2.86 in and weighs 400 grams, fitting in a backpack or carry-on for flight-friendly transport. Two USB-C and two USB-A ports let you charge four devices at once, while smart power distribution adjusts output across ports for stable performance and a double-press activates low-current trickle-charge mode for small wearables.

65 W recharge in 2.5 hours limits downtime

The power bank itself recharges at up to 65 W, reaching full capacity in about 2.5 hours, so downtime between trips is short. The built-in LED screen shows remaining battery level and charging status, but the 90 W single-port ceiling means very high-wattage laptops may charge more slowly under heavy load, and the fixed 5 V specification limits compatibility with devices that require higher voltage profiles.
