Its engineering focuses on combining durability, fast charging technologies, and safety certifications to offer reassurance beyond just raw numbers.

Detailed Specs & Features

On paper, the Sunslice Gravity 27 Pro shines with a series of thoughtful inclusions that set it apart in the power bank market. The battery capacity of 27000mAh, supported by a Lithium-Ion chemistry and cylindrical cells, frankly promises extensive recharge cycles per charge, fitting perfectly for multi-device users. This is matched with a 99.9% energy rating and an efficient 90% charging efficiency, making the conversion of stored energy impressively effective with minimal loss.

Inputs and outputs are comprehensive, featuring three input ports (USB-A, Micro-USB, USB-C) capable of a maximum input power of 60W, which is quite solid for recharging this large battery quickly. The five output ports accommodate wide compatibility, including USB-C and Lightning, with a total power output capped at 100W, ensuring powerful delivery also thanks to Power Delivery and Quick Charge technologies.
