Magnetic power banks keep getting thinner, and Black Shark just raised the bar again. The new Blade 2+ comes in two sizes that snap onto the back of a phone using N52 magnets. They can push up to 22.5W through a cable and stay thin enough that you might forget one is even there. Prices start at about $22 in China, where both versions went on sale this week as part of Black Shark’s spring 2026 lineup.

Black Shark is a sub-brand under Xiaomi. The name started out in gaming phones, but the Blade power bank line has turned into one of its most popular accessories. The original Blade stood out for packing a big battery into a surprisingly flat shape. The Blade 2+ pushes that idea even further with a better magnetic surface, upgraded materials, and a look that still feels like a gaming product without clashing next to an iPhone or Galaxy.
Two Capacities, One Obsessive Focus on Thinness
The smaller Blade 2+ holds a 5,000mAh battery and measures just 8mm thick, making it one of the thinnest magnetic power banks you can buy right now. That is thinner than most phone cases. At 105 grams, it is light enough that you will barely notice it stuck to the back of your phone. Wired output tops out at 18W, and wireless charging hits 15W through the magnetic connection. For a quick boost on a commute or a coffee run, 5,000mAh is enough for roughly one full charge on most modern smartphones.
The 10,000mAh model doubles the capacity without getting too bulky. It is 13.6mm thick and weighs 175 grams, still small enough to fit in a jacket pocket or a small bag. Wired charging on this version reaches 22.5W, which is close to what many wall chargers deliver. Both models support 15W wireless output, and because the magnets hold the power bank in place, you can keep using your phone while it charges.
What the UV Excimer Surface Actually Changes
Black Shark calls the Blade 2+ a slightly upgraded version of the non-Plus models. The main difference is the magnetic surface treatment. The company uses a UV excimer process on the contact area, which changes the texture and finish of the charging face. That is the key upgrade between the two generations.
In practice, this means a smoother and more consistent grip when the power bank snaps onto a phone. N52 magnets provide the holding force. These are the strongest type of neodymium magnets used in everyday electronics. With the new surface coating on top of that, the connection should feel secure enough for one-handed use without the power bank sliding or falling off. If you are looking for a magnetic power bank for iPhone, the Blade 2+ works right out of the box with any model from the iPhone 12 onward. For a magnetic power bank for Android, you will need a MagSafe-compatible case to get the same snap-on connection.
Gaming Roots Show in the Design Details
The Blade 2+ comes in two colors, Mecha Orange and Mist Blue. Both have a futuristic look that fits the Black Shark brand without going overboard on flashy gamer styling. The body is made from aluminum alloy, which gives it a solid, premium feel you would not expect at this price. LEDs on the outside show how much charge is left, and a side button lets you check the battery level with one press or turn the unit off with two quick taps.
What Powers the Blade 2+
Xiaomi says the batteries inside are “Apple-derived.” That does not mean Apple is officially involved. It likely means the cells come from suppliers associated with Apple products. The idea is that these are high-quality cells built for steady power output and long battery life. Both models support multiple charging standards and can charge two devices at the same time if you connect one wirelessly and plug another into the cable port.
Pricing and Availability Stay Locked to China for Now
The 5,000mAh Blade 2+ costs CNY 159, which works out to about $22. The 10,000mAh version is CNY 189, or roughly $27. Both are available on JD.com in China. An earlier version, the Blade 2, has appeared on secondary platforms like Qoo10, though the newer Blade 2+ has not been listed outside China yet. Xiaomi might bring the Blade 2+ to other countries eventually, but a wide global release does not look likely anytime soon.

The Blade 2+ launched alongside a broader Black Shark spring 2026 product lineup. The power banks are the most affordable items in the collection. At under $30 for the larger model, they cost much less than similar magnetic power banks from Anker and Baseus, which typically range from $40 to $70 for the same capacities. Whether or not Black Shark brings these to more markets, the Blade 2+ shows just how thin a magnetic power bank can get without giving up real battery capacity or fast charging speeds.
