From the shop's description

Step Down Module 9V/12V/24V to 5V 3A with Dual USB This is Dual USB Output 9V / 12V / 24V / 36V Car Charger Switch 5V DC-DC Power Supply Module 3A Buck Regulator, a combo of 3A Charger and voltage checker. The module converts input of 6-40V into a very stable 5V 3A output. The device features a 2 USB port through which you can charge your phone. While charging your device please consider that the output of this device is regulated at 5V 3A. Simply connect this device to the power supply, the voltage can be detected in real time. When you need the phone, IPAD, MP3 and other digital products to charge, connect it to a power supply and it will start supplying 5V 3A at its output. You can use this device which features 2 USB ports in Mobile Phones, flat-panel USB5V powered devices and many more. DC-DC DUAL USB STEP-DOWN BUCK MODULE – TECHNICAL SPECIFICATIONS: Input Voltage – 6V to 40V DC Output Voltage – 5V DC Max Total Output Current – 3A Split Between Both Ports Switching Frequency – 150KHz Conversion Efficiency – 92% (Max) Number of USB Ports – 2 Operating Temperatures – -40° to +85°C Weight – ±20g Dimensions (L x W x H) – 59 x 19 x 19mm Features : High efficiency and low ripple. With USB power indicator light. Maximum output 3A (at the same time with two mobile phones). Small and handy module. Easy to use. TYPICAL APPLICATIONS FOR THE DUAL USB 5V DC-DC STEP-DOWN BUCK MODULE: The awesome features of the Dual USB 5V Step-Down Buck Module make it great for many different electronics applications, although the unique functionality it offers makes it ideal for creating your own convenient 5V car charging ports. In fact, the only real limitation to this module is the fact that it can only supply 3A max current via both USB ports simultaneously, which means you can’t run two Raspberry Pi Boards at max power simultaneously. However, with that being said, you can certainly run two Arduino Boards at full power, or you could even choose to charge your phone while powering your projects – depending on what your needs are or where this module ends up getting installed or integrated.
