The BLUETTI X20 is a 153.6Wh (48000mAh) portable power bank built for laptops as much as phones: a 100W USB-C port, two USB-A ports, and a 20V DC port that delivers up to 160W through the twelve laptop adapter tips included in the box. With up to 288W of total output across four ports, it keeps a work-from-anywhere kit, camera bag, or campsite table running without hunting for a wall socket.
Inside is a LiFePO4 battery rated for 2500 charge cycles, managed by BLUETTI's BMS. Recharging happens through the USB-C port at up to 100W: with a 100W USB-C PD adapter (sold separately) it refills in about 2 hours, or about 3 hours with a 65W adapter. If you're unsure whether it suits your laptop or setup, we're happy to help before you buy. BLUETTI X20 Key Features:
