Magnetic power banks have become a must-have for anyone who treats their phone like an appendage. Black Shark's Blade 3 arrives with a clear aim: give iPhone users a compact, fast, and safe way to top up without fumbling for cables.
The Blade 3 comes in two sizes — 5,000mAh and 10,000mAh — and the bigger model still manages a respectable 1.38cm thickness and about 195 grams of weight. The smaller pack trims down to roughly 0.8cm and 115 grams for true pocketability. Both use a flat G3 curved design to sit flush against the back of iPhones, so the camera bump stays unbothered.
Under the shell, Black Shark fits high-density lithium cobalt oxide cells treated with an explosion-resistant coating. The 10,000mAh unit pairs two 5,000mAh cells and produces a rated output of 6,000mAh at 5V/2A. It’s not just numbers on a spec sheet: the company says the battery survives aggressive stress tests, including puncture, compression and drop trials — even enduring a 4mm tungsten steel needle puncture and withstanding up to 13,800kg of pressure.
The practical highlights are straightforward. You get 15W magnetic wireless charging tailored for iPhone 12 through iPhone 17 models and 30W wired charging over USB-C. Both USB-C ports support 30W input and output, so the Blade 3 can act as a fast charger and a quick-rechargeable power bank. Black Shark claims the Blade 3 charges an iPhone 17 Pro to about 70% in 30 minutes.
Thermal control reads like the feature section of a premium phone. The Blade 3’s Ice Armor system layers graphene sheets, dual-layer aerogel insulation, silicone thermal interfaces and an aluminum alloy shell to keep surface temps at or below 37°C. Dual NTC sensors work with AI-driven thermal management to adjust power delivery in real time, so speed doesn’t come at the cost of heat.
Magnetically, the module uses 17 N52-grade magnets with a peak pull force of 12.8N — enough to hold a phone steady but not so aggressive that it’s a frustration to remove. An LED battery indicator sits on the casing, while single- and double-tap shortcuts give quick battery checks or shut the unit off. It supports simultaneous wired and wireless charging, allowing you to power two devices at once: a phone on the back and something else via USB-C.
Compatibility isn’t limited to phones. The Blade 3 handles tablets, earbuds and other USB-C accessories too. It ships in Mist Blue and Obsidian Orange and arrives with an 18cm detachable braided USB-C cable. Black Shark also points to nine layers of safety protection and China’s 3C certification as proof of a safety-first design philosophy.
For anyone who likes ecosystem add-ons, the Blade 3’s launch follows on the heels of Black Shark’s new magnetic Bluetooth speaker for iPhones, which sports RGB lighting and up to 16 hours of use. Two new accessories, both aimed at iPhone users who want speed and flair.
So, is the Blade 3 the magnetic power bank that finally balances capacity, speed and peace of mind? It’s a convincing step — and one that raises the bar for rivals chasing a safer, faster MagSafe-style experience.
