How outlets covered it

Belkin has introduced two new semi-solid state portable batteries: a 10,000mAh model with USB-C and a 5,000mAh MagSafe model with 15W Qi2 charging. These new batteries are lighter than previous models due to their semi-solid state technology and feature aluminum builds.

The upcoming iPhone Duo will include a 4,883 mAh battery, which is larger than the battery capacities found in the Galaxy Z Fold 8 and Pixel 11 Pro Fold. This larger battery capacity is attributed to the iPhone Duo's thicker and heavier design compared to its Android foldable competitors.

Accessory maker BMX launched the BMX Duo, a 5,000mAh MagSafe battery pack specifically sized for the new iPhone Duo. This accessory addresses compatibility issues with existing MagSafe products due to the iPhone Duo's unique dimensions, offering 15W wireless charging and a 20W USB-C option.
