The weight is about 204.1 g (7.2 oz).
That's how big it is in the hand.
ChargerLAB POWER-Z KM003C shows that the USB-C port supports QC3.0, FCP, SCP, AFC, PD3.0, PPS, QC4+, DCP, SAM 2A, and Apple 2.4A charging protocols.
It also supports three fixed PDO profiles of 5V3A, 9V2.22A, and 12V1.67A, as well as two PPS voltage ranges: 5.00-5.90V3A and 5.00-11.00V2A.
When the power bank is attached to the back of the iPhone 17 Pro Max, the MagSafe charging animation appears on the phone.
The power bank does not obstruct the camera module.
It remains securely attached even when inverted and does not fall off.
The USB-C port delivers approximately 19.39W of wired charging power to the iPhone 17 Pro Max.
Teardown
Next, let's take it apart to see its internal components and structure.
Pry open the front metal panel along the seam.
Inside the front panel, there is a small piece of insulating high-temperature adhesive tape in the upper-left corner, used to secure the power button.
The insulating high-temperature adhesive tape is used to secure the power button and prevent it from detaching.
The upper section houses the PCBA module, while the lower section contains the battery. The battery surface is protected with fish paper insulation and high-temperature adhesive tape.
The PCBA module is secured with two screws.
Separate the battery and PCB from the plastic rear shell.
The inner side of the plastic rear shell is shown, with the wireless charging coil located in the center.
The wires are secured with high-temperature insulating adhesive tape.
A layer of white protective film is attached to the charging coil.
After removing the white protective film, a layer of gray magnetic shielding material is revealed underneath.
The edges of the battery pack are protected with green fish paper, insulating the battery tabs.
The battery is from JS, model 126280, with a capacity of 10,000mAh. It has a nominal voltage of 3.85V and an energy rating of 38.5Wh. The production batch is 2026A11A02, and it has passed CCC certification.
After removing the insulating tape and fish paper, the weld joint between the tabs and the wires is exposed.
