1. Made of high-quality aluminum alloy material, sturdy and 2. The shell is paired with a fast charging board and comes with a full protocol mobile phone for fast charging, making it convenient for various DIY modifications 3. The shell kit needs to be used in conjunction with the product module, and can be used in conjunction with models such as H3606, S3580, and S3606 power supplies 4. Adopting multiple input methods, supporting Type-C port with PD protocol fast charging head input, pure copper DC plug DC5.5 x 2.1 input DC6.0-30V input method 5. It is compact and can be widely used in various occasions, such as diagnosis and treatment electronic instruments, communication and broadcasting equipment, industrial electronic equipment, DC motors, charging equipment, etc. Finished product size: 83mmx84mmx90mm Interface:Type-C DC plug:DC5.5x2.1 DC input voltage:DC6.0-30V Current:15A (maximum) High compatibility: Supports the following fast charging protocols: for PD2.0 PD3.0 for QC4+/QC3.0 for SCP/FCP for VOoC for DASH for 2.4A for AFC for 9V2A dual engine for PE2.0 Attention: The maximum input voltage of the fast charging board is DC30V, so it is recommended to purchase a matching power supply with the highest input 30V. It is recommended to use it with our H3606, S3580, S3606 and other power supply models. If you choose a voltage reducing power supply with a comparable voltage, you can only that the input voltage is within 30V, otherwise it may cause overvoltage damage to the fast charging board. Please bear your own responsibility. Instructions for use: 1. When the phone is not plugged in for charging, the TYPE-C port nixie tube displays voltage,and the USB-A port displays temperature.When the phone is plugged in for charging, both TYPE-C port and USB-A port take turns displaying voltage and current. 2. On/Off button short : CNC power on and off, long for 2 seconds to switch CNC power on status: ON power on and on; OFF Power on and off. It's DIY kits, needs to finish by yourself.
