USB Charger Doctor Current Voltage Charging Detector Battery Voltmeter AmmeterUSB charger doctorDescription:
Can easily measure the operating current of the output voltage of the USB port and equipment 2. smallsize , no power , and other ancillary equipment, plug and play also detect USB charger output voltage and current are standard suitable for factories, Laboratory and users.
Technical indicators:
Scope of work: Current (0~2.5A) can detect mobile phone charger voltage compliance DC5V
Operating Range : U = 3 ~ 7.5V I = 0 ~ 2.5A
Resolution : Voltage 10mV current 1mA
Error : voltage <± 1% current <± 2%
Full scale drop : ( When measuring current ) 200mV
The tester uses a new generation of power four semi~ double loop integral converter IC , with a precision bandgap reference , range accuracy , high precision , stable and reliable performance , strong anti~interference ability , high temperature can be used for measuring USB powered or power consumption of the interface , mobile phone charger , U disk and other products.
1, USB powered devices can be used to measure air , voltage loads , USB terminal equipment working voltage and current .
2, The current and voltage cycle , easy to use and practical.
3, Compact and easy to carry , no additional power supply4USB Output Voltage Step Down Mobile Phone Charger 5AFeatures:
This 4USB DC-DC buck converter, suitable for power adapter, battery pack, car battery & mobile power voltage step down to 5V output to charge or power supply for the electronic equipment.Input voltage: DC 10V~35V (DC 12V/19V/24V battery is suitable)
Input power must higher than output.
Output voltage: about 5.3V(can charge for the IPhone/IPad and most Android phone, also can power supply for other 5V electronic equipment).
Output current:5A max(each USB 2A max, total 5A max. Please notice when input voltage below 11V, total output current maybe below 3A).
Input connect method: Please use 5.5*2.1 cm male power cable.
Size: 54 * 45 * 20（L*W*H, mm）, 56 * 47 * 26(mm, with shell)
This converter use wide voltage chip, main chip with current limiting function(6A), input low voltage automatic shutdown function. High quality chip can work better.
This module with two FM5888 dual recognition IC, it is USB charge protocol control IC, it can automatically identify the type of charging device, make device get the max charging current, protect device and save charge time.
Please notice, if you need to get the max charging current, your phone or device must support at the first.Package Included:1PCS *usb charger doctor / 1x DC10-35V 12V 24V to DC 5V 4USB Output Voltage Step Down Mobile Phone Charger 5A
