"SMARTCOBY SLIM II Wireless 2.0 8K", an 8,000mAh mobile battery with Qi2 support, is now available!
"SMARTCOBY SLIM II Wireless 2.0 8K" is a mobile battery that supports the Qi2 standard and can charge wirelessly up to 15W. With a battery capacity of 8,000mAh, it can charge a smartphone approximately once. With a slim body measuring approximately 12 mm in thickness and weighing approximately 162 g, the battery can be held on top of a smartphone without feeling uncomfortable. The aluminum alloy material with excellent heat dissipation and rigidity and liquid silicone on the back adsorption surface provide both a comfortable touch and durability.
Charging to the main body of the mobile battery corresponds to 20W and can be fully charged in about 120 minutes. It also supports "pass-through charging," which allows charging of the main unit while charging the device. When the main unit is fully charged, it automatically switches to a DC circuit dedicated to the device, which is designed to suppress battery cell deterioration.
Two output modes are provided to achieve both a low-profile design and to prevent heat generation. The "Safety Mode" suppresses temperatures in summer and other situations where heat generation is a concern, while the "High Performance Mode" can be selected for situations where charging speed is important. This is a device that meets the needs of users who want both thinness and charging performance.
The "SMARTCOBY SLIM II Wireless 2.0 8K" is priced at 7,680 yen (tax included). It will be on sale for 6,580 yen (including tax) during the "Amazon Prime Thanksgiving Sale" on Amazon.co.jp from October 4, 2025 (Sat.) at midnight until October 10, 2025 (Fri.) at 23:59.
