Product name: Square fast charging single USB+Type-C charger with voltmeter+button switch+integrated SAE socket+1m double SAE socket connection cable; Net weight of product: 136g; Product size: 66.6mm in length, 38mm in width, and 21.3mm in height; Input voltage: DC12V-24V; Monitoring voltage range: 6-30V Output voltage: USB port output: 5V 3.4A/9V 2.5A/12V 2A; Type-C output: 5V3A/9V2A/12V1.5A; Installation methods: handlebar installation and screw fixation (two fixed installation methods); Product purpose: It can be used to power most car products such as mobile phones, tablets, for iPads, navigation, and GPS; Scope of use: Can be installed on DC12V-24V vehicles, motorcycles, beach bikes, SUVs, boats and other means of transportation Product features: There are multiple protection functions: input overvoltage and undervoltage protection; Output overcurrent, overvoltage, undervoltage, and short circuit protection; Reverse connection protection; High temperature protection inside the chip Product advantages: The product comes with a single USB+Type-C fast charging port, and supports Type-C output and USB PD2.0/PD3.0 (), DCP ( and BC1.2), QC2.0/QC3.0, Fast Charging Protocol FCP and High Voltage SCP, Fast Charging Protocol AFC (MAX 12V), MTK PE+1.1, and MTK PE+2.0 fast charging protocols. It can automatically identify the fast charging protocols supported by the output end connected to the device The input voltage of the product is 12V-24V, which can be installed on vehicles such as cars, motorcycles, beach bikes, SUVs, boats, etc., with a installation range. The product is equipped with a built-in power MOS, which can provide a maximum output power of 20W. It can automatically adjust the output voltage and current according to the recognized fast charging protocol, thereby adapting to the maximum charging power of each mobile phone; And it has the function of automatic adjustment of overcurrent point. When the device connected to the Type-C interface supports high-voltage SCP, priority is given to outputting high-voltage SCP. Compared with PD output, the charging power is higher, and the maximum support is 10V/2.5A output The product has a line compensation function, which increases the output current and correspondingly increases the output voltage to compensate for the voltage drop caused by the impedance of the connecting line. It also has a soft function, which can prevent the surge current during startup from affecting the stability of the input power supply The product is equipped with voltage display, and the body of the product adopts high-end logo lighting, which is more beautiful and generous overall, meeting the aesthetic needs of customers The product comes with a waterproof cover, with a waterproof rating of IP66. Simply covering the cover waterproof, so you don't have to worry about it even in rainy weather The product comes with an button switch, which can be used and stopped with just one , making it easy and fast to operate Color: As Shown Material: plastic Package Contents: 1 * Handlebar mounting bracket 1 * Screw mounting bracket 2 * large screws 1 * Small screw 1 * Car handlebar fixing screw 1 * Anti slip gasket Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
