Product description
Product size: 35.5 * 17 * 8.3 mm
Input voltage range: 6 to 26 v
Output voltage: 5.2 V (consider charging line loss, output is about 5.2 V, the load end is around 5 V)
Limit the output current: 3 a (in the absence of radiator, stable output current limit is 2 a)
Note 1: is the cathode can't meet the, and the input voltage can't more than 26 v, otherwise it will result in the chip damage!
Note 2: in current work, not touch on the circuit board sampling resistor, IC, or may result in output voltage mutation damage equipment!
Name: Double USB output module 3A Step-Down
Input: 6V-40V (DC5.5/2.1 port, connecting terminal)
Output: 5V / 3A (MAX)(With Identification resistance for Apple)

Product Size: approx. 50*35*12mm/1.96*1.37*0.47''
9V 12V 24V to 5V DC-DC Step Down Charger Power Module Dual USB Output Buck 3A Car Charging Charge
DC-DC USB buck charging module (with work indicator, standard contact gold-plated socket)
Input voltage range: 6-24V
Output voltage: 5.2V (consider the charge line loss, the output is 5.2V or so, the load side is about 5V)
Output current: 3A (in the absence of heat sink device, the stable output current is 2A)
Note 1: positive and negative can not be reversed, and the input voltage can not exceed 24V, otherwise it will lead to chip damage!
Note 2: When working in power, you can not touch the circuit board on the sampling resistor, IC pin, otherwise it may lead to damage to the output voltage of the device!
For some of the poor electronic base customers say: Do not think the nominal 3A current will burn the phone burn equipment! Charging current is determined by the phone or equipment! Most mobile phone charging current is 0.8-1.5A.
