Baseus has expanded its Picogo Air AM71 magnetic power bank to global markets, and the device stands out for one clear reason: it is built to stay remarkably slim. Rather than chasing a large battery pack, Baseus has focused on portability, fast top-ups, and a design that is easier to carry every day.
The power bank carries a 5,000mAh battery, yet its body measures only 0.27 inches thick and weighs 3.7 oz. That combination puts it in the category of compact accessories aimed at users who want quick charging support without adding much bulk to a phone setup.
A slim body built with layered internals
To keep the profile as thin as possible, Baseus used internal components designed for minimal thickness. The charging coil is just 0.35 mm thick, while the NFC module measures 0.15 mm, and the battery uses high-density cells.
The outer shell is made from aluminum for structural strength, while the side that touches the phone uses fiberglass to reduce the risk of scratches on the rear panel. Those material choices help the product stay light and rigid at the same time.
Thermal management is another important part of the design. Ultra-thin wireless chargers can struggle with heat, so Baseus added aerogel and graphene sheets inside the unit to help move heat away from the battery.
The exterior also uses a grooved surface design that supports passive airflow while the power bank is in use. It is a small detail, but it reflects how much attention went into making the thin body practical rather than purely cosmetic.
Capacity is modest, but the use case is clear
Picogo Air AM71 is rated at 5,000mAh, or 19.4Wh, but the usable output is lower after energy conversion. In practical terms, that leaves roughly 2,750mAh to 3,250mAh available for device charging.
That makes the power bank better suited to partial top-ups than full recharges for larger phones. Baseus says it can bring a standard iPhone to around 68% and a Pro Max model to about 60%.
This places the device firmly in the “carry it for backup” category rather than the “depend on it for long trips” category. For users who mainly need extra battery during a busy day, that tradeoff may be more useful than a larger and heavier pack.
| Key Spec | Picogo Air AM71 | What It Means |
|---|---|---|
| Battery Capacity | 5,000mAh / 19.4Wh | Compact capacity for daily backup use |
| Body Thickness | 0.27 inches | Designed for a very slim profile |
| Weight | 3.7 oz | Light enough for regular carry |
| Wireless Output | Up to 15W | Magnetic wireless charging support |
| Wired Output | Up to 22.5W | Faster charging through USB-C |
| Recharge Input | 20W | Recharges the power bank through USB-C |
Wired and wireless charging both remain available
For users who prefer cable-free use, the Picogo Air AM71 supports magnetic wireless charging at up to 15W. That makes it a straightforward option for quick attachment and charging without needing extra accessories.
When faster output is needed, the USB-C port raises charging performance to 22.5W. The same USB-C port is also used to recharge the power bank itself, with input reaching 20W.
Baseus includes a 60W USB-C cable in the box, which adds convenience for users who want to switch to wired charging immediately. The bundled cable also helps make the product easier to use straight out of the package.
NFC support adds a layer of monitoring
One of the more unusual features in the Picogo Air AM71 is the built-in NFC tag. Tapping a phone against the power bank opens the Baseus app automatically.
That app shows remaining battery level, current temperature, and general battery health. It also manages trickle charging, lowering the power output once the connected phone reaches 80% to help reduce battery wear.
For users who keep a magnetic power bank attached for longer periods, that kind of control can matter. It shifts the product from a simple charging accessory into something that offers a more informed charging experience.
Safety, pricing, and availability
Baseus says the power bank includes standard protections against overcharging and short circuits. It also carries CCC certification and has passed durability tests that included extreme temperatures and pressure resistance.
The Picogo Air AM71 is available in silver and black. In the U.S. market, Baseus lists it on Amazon for $69.99.
In Europe and the U.K., the same product is sold through the Baseus store for €69.99 and £69.99. With its slim construction, magnetic charging support, and app-based monitoring, the Picogo Air AM71 is positioned as a premium option for users who care more about portability than maximum capacity.
