Baseus has launched the Picogo Air AM71, a 5000 mAh magnetic powerbank measuring just 6.8 mm in thickness. The device features 22.5W wired charging and an integrated NFC chip that automatically opens the Baseus app on compatible smartphones to provide real-time battery health and temperature data.
How extreme miniaturization is redefining mobile accessories
While many portable chargers prioritize high capacity, Baseus is targeting users who prioritize a slim profile. The Picogo Air AM71 weighs approximately 105 grams and measures 6.8 mm thick, allowing it to attach to the back of a smartphone without significantly altering its form factor.
To achieve this thickness, Baseus utilized specialized internal components. According to company specifications, the device contains a 0.35 mm ultra-thin charging coil and a 0.15 mm NFC module. These components are integrated alongside high-density lithium battery cells to maintain a minimal footprint.
The rise of smart-connected power solutions
Instead of relying on simple LED indicators to show charge levels, the NFC chip triggers the Baseus application upon contact. This allows users to monitor specific metrics including:
- Real-time battery percentage
- Current operating temperature
- Total charge cycles
- Overall battery health
This software integration also enables “drop charge” modes. The Baseus app can automatically reduce power delivery once a smartphone reaches an 80% charge level, a feature designed to extend the long-term lifespan of the host device’s battery.
Why thermal management is the next frontier for thin electronics
As powerbanks become thinner, managing the heat generated by wireless charging becomes more difficult. Baseus has addressed this by incorporating materials typically found in aerospace applications. The Picogo Air AM71 utilizes an aerogel layer and graphene sheets to move heat away from the battery cells.
The exterior design also plays a role in cooling. The device features an aluminum casing with a grooved surface to encourage passive airflow. The contact surface that touches the phone is coated in glass fiber to prevent the metal casing from scratching the smartphone’s rear panel.
Comparing portability vs. capacity: Baseus vs. Belkin
The following table compares the recently announced Baseus model with a high-capacity alternative from Belkin.
| Feature | Baseus Picogo Air AM71 | Belkin (Recent Model) |
|---|---|---|
| Capacity | 5000 mAh | 10.000 mAh |
| Max Wired Output | 22.5W | 45W |
| Primary Benefit | Ultra-thin/Minimalist | High speed/High capacity |
While Belkin focuses on users needing multiple full charges and faster speeds, Baseus is positioning the Picogo Air AM71 as an “emergency companion” meant to provide a quick boost during the day.
Pricing and availability
The Picogo Air AM71 is available in black and silver. It is priced at $69.99 in the United States, €69.99 in Europe, and £69.99 in the United Kingdom. Each unit includes a 60W braided USB-C cable for high-speed data and power transfer.
Based on Baseus test data, the 5000 mAh capacity provides a net delivery of between 2750 and 3250 mAh to the phone. This is sufficient to charge a standard iPhone to approximately 68% or a Pro Max model to approximately 60%.
Frequently Asked Questions
