FEATURES --- Constant current/voltage mode; Voltage calibration & current calibration; USB interface; Protective case; Short-circuit protection; Over-temperature protection; Input reverse connection protection.

NOTE --- 1). Output voltage is set as around 20V by default, if your input is lower than that, please turn potentiometer anticlockwise for 10 laps or more until voltage changes. 2). The case is packaged unassembled to avoid damage during transit. It needs to be manually installed. 3). Please carefully read the user’s manual, especially the “Cautions” before using. You can find the PDF Instructions on this page -- Product information -- Product guides and documents -- User Manual [PDF].

Protection --- The battery power detector comes with protective shell, dust proof waterproof surface and input reverse connection protection.

Application --- This multimeter can be used as battery voltage meter, battery capacity tester and temperature indicator panel for car, marine, RV, boat, etc.

Alarm --- If the small battery indicator gauge is in the condition of a low voltage, its red indicator will flash and buzzer will alarm.

Data Save --- The boost converter can save up to 10 sets of parameter settings. It’s easy to save and very convenient to call out parameters at any time you would like to.

Wide Application --- The step up power converter does great for wind power, DC generators, solar panels to charge battery, and it also can be made as a boost power supply to power devices.

Notes --- 1) No big difference between input and output voltage. Otherwise the power loss will increase then the actual output may not be as what expected; 2) Actual output current is mainly decided by the load. Converter can only set a limit on output current; 3) When powering high-power appliances, please turn off the automatic output function, correctly connect the converter, and then press the "OK" button to output. After the voltage rises to the set voltage, turn on the appliances.

APPLICATION: the usb to DC 12V cable can be used to power the router via power bank if power down. In addition, can also be applied to other device which is 12v power supply, such as small fan, desk lamp, solar panel, USB power pack, power adapter, speakers that requires for 12V poewr and bluetooth audio etc.

CONVENIENT USE: plug and play, you can still enjoy the WIFI during power cuts; design with small dimension, is very convenient to carry out.

One Year Long Time Warranty: If there's any question for using or quality please contact us to get a replacement or refund.

PROTECTION --- this voltage stabilizer comes with over-current protection, over-temperature protection; adopts potting technology, characterized by waterproof, dust-proof, moisture-proof and shock-proof, can be used in various situations such as car, outdoor, underground, etc.

FEATURE --- the step down power module adopts high-integrated chip, stable and reliable; synchronous rectification technology, with conversion efficiency of over 90% and low heat generated.

NOTE --- Leave a margin for the power supply to ensure it can long-term stably working.

【Constant Current and Voltage with Indicator Lights】This volt transformer board can set constant output voltage and constant output current by the key buttons. Also, the module is equipped with working status indicator lights, which are output OUT, constant voltage CV and constant current CC respectively, so that the working status can be checked in real time.

【Auto Output and Button Lock Mode】Automatic output can be set after power on. And The parameter adjustment button can be locked to prevent misoperation to adjust the output voltage and current parameters.

【Cooling fan and cooling pad】This adjustable power supply converter is equipped with cooling fan and cooling pad which can keep it cool when it’s too hot.

Flat Plug: Designed as a flat plug, this volt tester can immediately detect and measure the current voltage by connecting to the switch plug or other kind of wall socket, simple and easy to use, it allows you to check on power health of devices for preventing the low voltage damage to your valuable household appliances.

LCD Display: Built in Premium LCD digital display with blue backlight, this voltage monitor is convenient for you to view the data on it even in dim night. Moreover, it can be used as a voltage meter as well as a night light.

Wide Applications: It is ideally applicable to measuring the AC voltage in family, office space, industrial and mining enterprises, etc. (Please keep the children away from the product & do not use the product in a damp environment.)

【Easy Operation】 A user manual will be included in package, which can help you easier to operate. The button can control ouput voltage ON/OFF status, and you can set the default output state is ON/OFF for the next time. The potentiometer can help you to adjust volt amp in a simple and fast way.

【Protection】 It has reverse-connect protection, short circuit protection and over current protection. When you connect the input wire reversely or short circuit, the module will not burn. And roate the CC potentiometer to set over current protection value you want.

【Application】 The volt conversion board can be used for 5v 6v 9v 12v 24V 30V 32V 3a 5a 10a devices, like solar panel, lab, experiment, RV, All-Terrain Vehicle, car, battery charger, LED stripes, etc.
