Massive 20000mAh Battery Capacity
The Baseus Comet Series is powered by a substantial 20000mAh / 77Wh Polymer Lithium battery, providing a large reserve of portable power for compatible smartphones, tablets, wireless accessories, and other everyday electronics. Its energy conversion rate is rated at 75% or higher, helping provide efficient power delivery from its high-capacity internal battery. This combination makes the Comet Series particularly suitable for extended travel, long working days, commuting, outdoor activities, and emergency situations where reliable access to a conventional wall charging outlet may be unavailable for long periods.
Up to 22.5W Fast Charging
Designed for efficient everyday charging, the Baseus Comet Series supports up to 22.5W fast charging through its built-in Type-C cable. The Type-C cable supports 5V/2.4A, 9V/2A, 10V/2.25A SCP, and 12V/1.5A output profiles. The dedicated Type-C port supports 5V/2.4A, 9V/2.22A, and 12V/1.5A output. This flexible charging configuration helps compatible smartphones and other supported devices replenish their batteries faster than conventional low-output portable power banks.
Dual Built-in Type-C & Lightning Cables
One of the biggest advantages of the Baseus Comet Series is its dual built-in fast-charging cable design. The integrated Type-C cable supports fast charging up to 22.5W, while the built-in Lightning cable supports 5V/2.4A and 9V/2.22A, providing up to approximately 20W for compatible Apple devices. Having both cable types attached directly to the power bank reduces the need to carry additional cables, creating a cleaner and more convenient charging setup for users carrying devices with different charging interfaces.
Dual-Way Type-C Fast Charging
The Baseus Comet Series features a versatile Type-C interface with both input and output support. For input, the Type-C port supports 5V/3A, 9V/2A, and 12V/1.5A, allowing the power bank itself to recharge efficiently with a compatible charger. The Type-C port also provides fast output for supported devices. This dual-way charging capability makes the power bank more convenient for everyday use because one modern Type-C connection can be used both to replenish the power bank and provide power to compatible electronics.
Smart Digital Display & Modern Design
A built-in smart digital display allows users to monitor the remaining battery level in real time, providing clearer information than conventional multi-dot indicator lights. This makes it easier to determine whether sufficient backup power remains for another charging session or whether the power bank should be replenished before travelling. The Comet Series also features a distinctive semi-transparent shell design, giving the power bank a more modern and visually appealing appearance compared with conventional solid-body portable chargers.
Multi-Protocol Support & Small-Current Mode
The Baseus Comet Series supports a broad selection of mainstream fast-charging protocols including PD, QC, AFC, FCP, and SCP, improving compatibility with supported devices from different manufacturers. It also includes a dedicated Small-Current Mode designed for lower-power electronics such as wireless earbuds, smartwatches, and electric toothbrushes. This feature expands the power bank’s usefulness beyond smartphones and tablets, making it a more versatile everyday charging solution for users who carry multiple types of personal electronic accessories.
