Applications:

DIY Mobile Power Supply, to achieve 5V output for charging Phone,PAD,PSP etc. DIY Car vehicle USB Charger Android IOS Mobile phone charger Smart home / home automation Distributed Power Systems Battery Charger Pre-Regulator for Linear Regulators

Attention :

This is a DC-DC voltage converter module,Must be noted when using: 1 Input voltage can not be greater than the maximum input range 2 Output power can not be greater than the maximum load for a long time 3 Input power must be greater than the output power, because the power consumption of the module itself

The charger can support most mobile phones and PAD charging. But there are still some digital products need identification resistor,If this is the case, please refer to the original charger, increasing identification resistor
