3V To 5V 1A USB Charger DC-DC Converter Step Up Boost Module For Phone

The 3V to 5V 1A USB Charger DC-DC Converter Step-Up Boost Module is a compact and efficient power conversion module designed to provide a stable 5V output from a low-voltage DC power source. This module is ideal for applications requiring a 5V USB output, such as charging smartphones, powering small USB devices, and DIY electronics projects that require a stable power supply.

Features:

• Module uses the Taiwan production boost chip, high efficiency (up to 92%), plus
• built-in over-current protection chip, can be more good to protect the module and use the device after the class. 
  
• Module with undervoltage protection, undervoltage protection into state below 2.5V, can be more better protect the battery, to avoid excessive discharge. 
  
• Module can modify the fixed resistor adjusts the output voltage can be adjusted up to 12V output, but to ensure that the output power of less than 5W. 
  
• This module uses TDK multilayer ceramic capacitors as main filter capacitor, the output ripple can be as low as 20mV (5V1A output case)! 
  
• This module uses a standard USB interface, you can use all universal USB charging mobile phones, MP3, MP4 and other equipment, the perfect support for IPHONE and other mobile phone.

Application:

• This module can be used for DIY mobile power output, enabling single or two ordinary lithium battery to 5V boost to the mobile phone or PSP device charging.
  
• DIY a mobile power supply, only need one battery, you can output 5V voltage for your phone, MP3, MP4, PSP charger, very easy. 
  
• In order to power your electronic devices when your device needs 5V power supply, when you only have lithium battery, this module can be directly step-up to 5V, solve your problems.

Note:

• This module is a fixed 5V output module.
  
• Modules indicated above IN - (negative input), IN + (positive input), OUT-(negative output), OUT + (positive output) must be connected correctly, otherwise it may cause damage to the module. 
  
• This module has an LED light, when the charge when the LED lights can be used as indicator.
