Black Shark has launched the Blade 3 magnetic power bank with a 10,000mAh battery in China. The device is listed on JD.com at a starting price of 259 yuan ($37) and supports 30W wired charging alongside 15W magnetic wireless charging, with a focus on iPhone compatibility.
Black Shark Blade 3 Specifications
The power bank comes in two capacity options: 5,000mAh and 10,000mAh. The 10,000mAh version measures 1.38cm in thickness and weighs about 195 grams, while the smaller 5,000mAh version is slimmer at around 0.8cm and weighs 115 grams. Both versions use a flat G3 curved design to fit flush against the back of iPhones, without interfering with the camera bump.
Black Shark uses high-density lithium cobalt oxide battery cells with an explosion-resistant coating. The 10,000mAh variant uses two 5,000mAh cells and delivers a rated output of 6,000mAh at 5V/2A. The battery has passed puncture, compression, and drop resistance tests. According to the company, the power bank can survive a 4mm tungsten steel needle puncture and withstand up to 13,800kg of pressure.
The device supports 15W magnetic wireless charging and works with iPhone 12 through iPhone 17 series models. It also supports 30W fast charging over USB-C, with both USB-C1 and USB-C2 ports capable of delivering 30W input and output. Black Shark claims the power bank can charge an iPhone 17 Pro to around 70% in 30 minutes.
The Blade 3 features an Ice Armor thermal management system that uses graphene sheets, dual-layer aerogel insulation, silicone-based thermal materials, and an aluminum alloy shell. This design keeps surface temperatures at or below 37°C, while dual NTC temperature sensors and AI-based thermal control dynamically adjust power output in real time.
The magnetic module uses 17 N52-grade magnets with a maximum magnetic force of 12.8N. The device includes an LED battery indicator and supports single-tap and double-tap shortcuts for battery check and power off. It also offers dual-device charging, support for wired and wireless charging at the same time, and compatibility with smartphones, tablets, earbuds, and USB-C accessories.
The Blade 3 power bank comes in Mist Blue and Obsidian Orange. It ships with an 18cm detachable braided USB-C cable and includes nine layers of safety protection. It has received China’s 3C safety certification.
