DC-DC Boost Module (0.9V~5V) Boost 5V 600MA USB Boost Circuit Board Mobile Power Boost

Disclaimer: The output power of this module is not only affected by the load capacity of the module itself, but also by various factors such as the front-end power supply and back-end load; The following data are the results measured by professional equipment, without considering other factors.
The power module is a type of electronic component, please purchase it with caution if you do not have electronic expertise.
1. This module adopts high-performance imported chips, which perform better than ordinary modules.
2. Input any DC voltage from 0.9V to 5V, and you can stably output 5V DC voltage. With a single AA battery, you can output up to 200-300mA of current. With two AA batteries, you can output 500-600mA of current. It can provide power for your mobile phone, camera, microcontroller, and digital products
3. Industrial grade temperature range: -40 ℃ -+85 ℃
4. High conversion efficiency, up to 96%
5. Equipped with a USB socket, widely used
6. Ultra small volume (PCB board 25mm * 18mm), suitable for installation in various small devices
7. With work indicator light
Scope of use:
1. DIY mobile power supply: When you feel that your phone, MP3, MP4, PDA, or PSP is not charging enough while on a business trip or trip, and you have extra batteries, you can consider DIY a mobile power supply yourself; As long as you choose this module and add your [one lithium battery or 2-3 nickel batteries], you can output 5V voltage to charge your phone, MP3, MP4, PDA, and PSP, which is very simple and convenient.
2. Adjust voltage: If you need a different voltage power supply during product design and the device requires 5V power supply, then choose our module
3. Stable power supply: When your power supply is unstable, sometimes high and sometimes low, but when your device requires 5V power supply, then choose our module
Does this power module have short-circuit protection? Will it burn out if I accidentally input a short circuit while using it?
Answer: There is no short-circuit protection. If you need short-circuit protection, please connect a self recovery fuse in series at the input end.
Buyers should be aware that some manufacturers may add identification resistors to products such as MP3MP4 phones for their own 
So if the buyer finds that this module cannot be used after purchasing it, please check if an identification resistor has been added.
