★ its a DIY kit, u need to fit all the things in casing. it took less than 5 minute... ★ Since 20volts is mentioned as Best input voltage range i used my old laptop Adapter 20v, 4.5A. Wow the setup is now complete. Calibrate it if needed ★ This tiny device Works perfectly, we can get desired output colt as per our need. i main use 2.8 v, 3.3v, 4.5v, 6v, 9v, 12v, 14.5v ★ i set 14.5v as output and charged my 12v 5Ah battery ★ its peak current is 3A. but using devices upto 2 to 2.5 Amps is a good choice
