When using digital gadgets, the "mobile battery" is now an essential item as a power source. Until now, there were few design variations, and most of them were dull. Good news for the battery world. The AFU store (Shin Sankai Co., Ltd.) has announced the beautiful, multi-functional and large-capacity skeleton battery “STORM2”. Currently, we are looking for support on the crowdfunding site "Makuake", but we can try the product this time. Let's report the feeling of use immediately. [Image] "STORM2", which features a solid skeleton body, is the size of a 350ml can of cola. It weighs about 590g, so it doesn't bother you to carry it around. Still, it has a large capacity of 25,600mAh / 99.36Wh, enough to charge a smartphone about 7 times. It is also possible to bring it on board an airplane. Overall, the size and weight feel comfortable in my hand, and I feel that everything is "just right". I tried charging my laptop as a test, but it was able to charge without any problem. It's just the right size and weight to carry around, and above all, the beauty of the board and LED screen that can be seen through the skeleton housing is eye-catching. By default, the LCD screen displays voltage, current, temperature, connection status, etc. Use the USB Type-C and DC ports when charging the battery itself. With USB PD in 100W mode, rapid full charging can be done in about 1.5 hours. The DC port is compatible with a dedicated solar panel and can be used outdoors. There are various ports used for charging other devices, such as USB Type-C and Type-A ports for output, USB Type-C for input and output, and general-purpose DC ports, not only for smartphones and tablets. , Outdoor refrigerators (24V), notebook PCs, DC compatible soldering irons (12V), drones (22.8V), and various other things can be charged. These terminals are organized on the side of the main unit and are easy to use. In addition to displaying the current and voltage values flowing through the currently connected device on the main unit's LCD, you can also finely adjust the voltage value according to the device that supplies power by clicking the button on the side of the screen. In addition, when using a DC power supply to charge other products, it is necessary to manually set the voltage, so please be careful of overvoltage and overcurrent. Let's charge with the corresponding voltage. Then, let's try charging with a DC power supply. First, check the voltage value of the device you want to use. In this case, "OUTPUT 14.5V" is written on the AC adapter, so enter this value in "STORM2". Press and hold the button on the side of the "STORM2" screen to select "DC", and press and hold again to display the "DC OUTPUT SETUP" menu. You can change the voltage value here. It can be changed in units of 1V and even in units of 0.1V, so it can be used with various devices (it is dangerous if you make a mistake here, so be careful). Also, charging using the USB Type-C port was no problem. The LED lamp for charging confirmation also lit up. "STORM2" is a state-of-the-art mobile battery with an outstanding design and many built-in terminals and functions. For those who like batteries with sharp appearance and functions, it can be said that it is a product worth considering purchasing. ■ "STROM2" specifications ・Brand: SHARGEEK ・Product name: Mobile battery STORM2 ・Model number: STM2-2 ・Weight: Approx. 590g ・Body size: Approx. : 25600mAh 93, 5Wh DC input: 5-24V/3A USC-C input: 5V/9V 12V/15V-3A 20V-5A 3.3-21V-5A DC output: 3.3-25.2V-3A USB-A Output: 5V-3A 9V-2A 12V-1.5A, USB Type-C1 Output: 5/9/12/15-3A 20V-5A 100W, USB Type-C2 Output: 5V/9V-3A 12V-2.5A 15V- 2A 30W Battery model: INR18650-32E 18650 3200mAh Li-ion
