Why It Made The List

A rugged power bank built to take a real beating outdoors, not just sit in a laptop bag waiting for the next phone top-up. The Poseidon XL has a 27,000mAh capacity, 100W USB-C input and output, and enough stored charge for 1.5 boosts of a 13-inch laptop, making it useful for cameras, drones, laptops and even a Starlink Mini. Two USB-C outputs, two USB-A outputs and an XT60 solar input let it sit at the centre of a proper travel, camping or emergency power set-up. IP68 waterproof, dustproof, crushproof and built to exceed MIL-STD-810G drop standards, it’s seriously robust backup power for the car, backpack, suitcase or home drawer, when you need power on the move or in an emergency.
