USB Power Meter, Electronic Load Tester, 35W Discharge, 4-30V DC, 0.1-4.5A Current, LCD Display, Aluminum Heat Sink

Description: This is a device used to simulate an electrical load, usually for testing purposes. This discharge tester is used for testing a battery or power bank. It can also be used to test current of a USB cable so you could judge if the cable is of good quality. It is designed with a aluminum heat sink and a cooling fan for better heat dissipation, which will start working automatically when temperature is higher than 55°C and stops when temperature is under 45. Specifications: Voltage Range: 4-30V DC Test Current: 0.1-4.5A Temperature: -10 to 65°C Size: 105 x 55 x 43mm / 4.13 x 2.16 x 1.69" Heat Sink Size: 40 x 40 x 10mm / 1.57 x 1.57 x 0.39" Constant Discharge Current: 0.1-4.5A adjustable(coarse adjustment knob for 0-3A, fine adjustment knob for +/-0.2A) Current Error: Less than 2%+3mA Constant Rated Discharge Rate: 35W(if voltage is 21V, constant discharge current should be less than 1.6A) Package Includes: 1 x Load

• Multifunction: This electronic load can real-time monitor voltage, current, capacitance, energy, power and timing, whose data can be stored automatically after power off
• Input interface and Output interface: USB input; clip-wire interface; socket with fast charging decoy device/ continuous parallel application interface
• With LCD: These is a small LCD display that you can check voltage, current and capacity
• Nice design: Designed with a high standard aluminum heat sink in the middle for better heat dissipation
• Operating temperature: The cooling fan of 2900rpm will start working when temperature is higher than 55°C and stops when temperature is under 45
