Baseus is drawing attention again with a power bank that focuses on one thing many users still want most: serious charging power in a body that barely takes up space. The Baseus Card Magnetic Air measures only 6.9 mm thick, yet it still packs a 5,000mAh battery, 22.5W wired fast charging, and up to 15W wireless output.
That combination makes it one of the thinnest power banks currently announced in its category, especially for users who want something light enough to carry every day. It was launched in China in late October 2025, and its mix of slim design, magnetic attachment, and smart battery features is already making it a noteworthy product for mobile users and gadget watchers.
A power bank designed to disappear into daily carry
The most striking part of the Baseus Card Magnetic Air is its form factor. At 6.9 mm thick, it is close to the size profile of a credit card, which makes it far easier to store in a wallet, jacket pocket, or small sling bag than traditional power banks.
Baseus also uses a matte finish with rounded edges, which helps the device feel more secure in hand despite its extremely slim shape. The magnetic back lets it attach directly to compatible phones, including iPhone models that support MagSafe, so users can charge without holding the power bank in place.
This design choice targets a clear audience. Many people still carry power banks that are too bulky for daily use, even when only a small battery boost is needed. Baseus is trying to solve that problem by making a charger that feels more like an accessory than a separate device.
Charging speed that matches the slim body
A thin device often raises a common concern: does the battery sacrifice speed or usefulness? In this case, Baseus says the answer is no, because the Card Magnetic Air supports 22.5W wired charging through its USB-C port.
That wired output is strong enough to deliver a meaningful top-up in a short time, and Baseus claims it can bring some flagship phones from 0% to 50% in about 30 minutes. For users in a rush, that kind of speed can matter more than total capacity.
The wireless side also gives the power bank more flexibility. The device supports up to 15W wireless charging for Android phones using Qi EPP and 7.5W for iPhones, which keeps it within the expected range for mainstream magnetic wireless charging accessories.
Charging options at a glance
- USB-C wired output up to 22.5W.
- Wireless charging up to 15W for compatible Android devices.
- Wireless charging at 7.5W for iPhone models.
- Simultaneous charging for two devices at once.
The ability to charge two devices at the same time is a practical addition, especially for travelers, commuters, or users sharing a power source in emergencies. One device can charge through USB-C while another sits magnetically on the wireless pad.
Battery capacity built for quick rescue, not full-day replacement
The 5,000mAh battery inside the Baseus Card Magnetic Air is not large by modern power bank standards. However, the goal here appears to be portability first and emergency power second, which is consistent with its ultra-thin design.
For many smartphone users, 5,000mAh is enough to restore a dead phone to a usable level or extend screen time until they can reach a wall charger. That makes the product useful for short trips, long commutes, meetings, or nights out, where carrying a heavy brick-style power bank feels unnecessary.
This positioning is important because not every power bank needs to be built around maximum capacity. Baseus seems to be targeting a user who values convenience and speed of access far more than multiple full recharges.
Baseus leans on safer battery technology
One of the more interesting claims around this device is its use of a solid-liquid hybrid battery cell. Baseus says this combination of solid and liquid electrolyte materials improves thermal stability and lowers the risk of overheating.
That matters because battery safety has become a bigger concern as cheap, unbranded power banks continue to flood online marketplaces. Reports of swelling, overheating, and even explosions have made many buyers more cautious, especially in compact devices where heat management is harder.
Baseus says the Card Magnetic Air went through extreme safety testing, including:
- Needle puncture testing without explosion or leakage.
- Pressure resistance up to 2 tons without structural failure.
- Operating temperature range from -60°C to 140°C.
Those figures are notable because they suggest the company is trying to market the product not just as slim, but as durable under stress. The testing claims also fit a broader trend in portable charging products, where safety is becoming a key selling point rather than an afterthought.
Smart features add a more premium feel
The Baseus Card Magnetic Air goes beyond simple charging hardware by adding NFC-based and AI-driven functions. One of the main features is PowerSense NFC, which allows compatible users to tap their phone against the power bank and see battery-related information in the Baseus app.
That information includes the remaining battery percentage, internal temperature, and an estimated charging time. For users who keep track of battery health and charging behavior, that makes the device feel more like a smart accessory than a basic charger.
Baseus also says it includes AI-powered device detection. The power bank can identify the connected device and adjust output automatically, whether the connection is wired or magnetic. That can help reduce the risk of wasted power and may also improve battery longevity by avoiding unnecessary charging stress.
What users get from the smart features
- Real-time battery status through NFC.
- Internal temperature monitoring.
- Estimated time to full charge.
- Automatic power adjustment based on the connected device.
These additions may not sound essential at first, but they help the product stand out in a crowded market where many slim power banks look similar. In practice, smarter power delivery can also improve the overall user experience because people do not need to guess whether the charger is working as expected.
Price and availability remain the biggest question
In China, the Baseus Card Magnetic Air is priced at 299 yuan, or around $41 USD. That puts it in a relatively accessible range for a premium-looking charging accessory, especially considering the ultra-thin design and added smart functions.
Baseus has not confirmed global availability yet. The company’s products often reach markets outside China later through official distributors or import channels, and Indonesia is one of the regions where Baseus accessories already have strong visibility through major e-commerce platforms.
The device comes in black, white, and metallic gray, which gives it a clean and minimalist appearance that fits its overall concept. If it does arrive in Southeast Asian markets, it could appeal to users who want a stylish and pocket-friendly charger without moving up to larger, heavier models.
Why this model stands out in a crowded power bank market
The power bank market is full of products that promise fast charging, but many still rely on thicker bodies and heavier packs to deliver those speeds. Baseus is taking a different route by combining ultra-thin construction with enough charging output to remain practical.
This matters for people who prioritize mobility. Office workers, frequent travelers, remote workers, and smartphone users with compact carry habits often want a charger that adds little bulk but still offers reassurance when battery levels drop.
The Baseus Card Magnetic Air fits that need by balancing three things at once: a very slim shape, decent charging speed, and a safety-focused battery design. The result is a product that feels more refined than a typical emergency power bank and more useful than a decorative accessory.
For users who have long wanted a power bank that can slip into a wallet-sized space without feeling underpowered, Baseus is offering a clear answer in the form of a 6.9 mm magnetic charger that still supports 22.5W wired output and smart wireless charging features.
