this is really nice for making a home made charger from a battery you have laying around, i picked mine to be a 12 V scooter battery, and it works great! i also tried a 24v camper battery for a short time, and it works awesome too! <BR>-fast charging (compared to another regulator i tried) <BR>- small size (great for custom chargers) <BR>-2 ports! I run my phone and portable speakers for hours!

It supports a wide range, and give a constant 5v with some tolerance. Small relatively size, USB port on output, and input side has screws so you can freely plug and unplug wires from it without soldering. <BR>Strong USB port <BR>-Has a Red LED LIGHT
