Supporting the latest Qi2 wireless charging standard, the battery provides up to 15W high-speed wireless charging, which is approximately twice the speed of conventional Qi charging. Its MagSafe compatibility ensures precise magnetic alignment with MagSafe-enabled iPhones, guaranteeing stable charging without misalignment.
SemiCore Semi-Solid State Battery Adoption
This product incorporates a semi-solid state battery that adheres to MATECH’s proprietary “SemiCore” quality standards. SemiCore is a quality standard that only uses cells that have cleared unique safety evaluations, including charge/discharge stability, temperature resistance, and durability.
Furthermore, it has passed rigorous safety tests such as:
-
Nail penetration test
-
Pressure test
-
High-temperature test
-
Low-temperature test
Compared to traditional lithium-ion batteries, it offers superior thermal stability, safety, and durability, maintaining stable performance even during high-output operation.
Max 22.5W Fast Charging Support
The USB-C port supports a maximum output of 22.5W. It is compatible with major fast charging standards including PD3.1, PPS, QC3.0, QC2.0, AFC, FCP, and SCP, enabling rapid charging for smartphones and tablets. It supports both wireless and wired fast charging, offering flexible usage options.
Approximately 100 Minutes for Full Battery Charge
With support for up to 18W USB-C input, the battery can be fully charged in approximately 100 minutes. It also features pass-through charging, prioritizing smartphone charging before automatically recharging the mobile battery itself. This allows for efficient charging even with limited time before going out.
- This estimate is based on using an 18W or higher USB-C charger. Actual times may vary depending on the usage environment.
