Global consumer electronics brand Baseus has officially released the PicoGo AM31 Ultra-Mini Power Bank, positioned as the world's smallest 5000mAh wireless power bank with Qi2 certification. Designed with portability and versatility in mind, the AM31 combines 15W Qi2 magnetic wireless charging, a built-in kickstand, and dual-device fast charging, all in a form factor comparable to a credit card.
The AM31 is part of Baseus' PicoGo product line, a new series of card-sized magnetic power banks aimed at redefining how users stay powered on the go. The AM31 is the first model in the lineup to feature both Qi2-certified charging and a hands-free kickstand, making it ideal for content consumption, video calls, and multitasking while charging.
Compact Design with Functional Engineering
Weighing just 0.29 lbs and measuring only 3.46 x 2.40 x 0.52 inches, the AM31 fits easily into small bags or pockets. It features a premium aluminum alloy casing with a soft silicone finish for added comfort and grip. The pop-up kickstand offers upright or side-view angles, effectively turning any flat surface into a functional phone dock.
Its magnetic snap-to-charge design ensures secure alignment with compatible iPhones and Qi2-supported Android devices, even through lightweight cases. The form factor and integrated features make it well suited for mobile professionals, commuters, and travelers seeking hands-free convenience.

Qi2 Fast Charging + Dual Output
The AM31 supports 15W Qi2-certified magnetic wireless charging, offering twice the speed of standard 7.5W MagSafe options. Qi2 enhances charging efficiency and magnet alignment while reducing energy loss.
Additionally, the AM31 features a 20W USB-C output, allowing users to charge a second device simultaneously. Combined with its wireless output, the AM31 enables dual-device charging on the go. Each unit includes a durable braided USB-C cable.
Advanced Cooling System for Safer Charging
Despite its ultra-slim build, the AM31 is equipped with Baseus' proprietary Triple-Cooling System, comprising:
- An aluminum alloy shell for structural cooling
- A graphene-based heat dissipation layer with a surface area of 5,119 mm²
- An NTC smart temperature control chip that monitors internal temperature up to 18,000 times per hour
These elements work together to deliver a cooler and safer charging experience, even during dual-output scenarios or prolonged use.
