Dual USB current and voltage tester Dual output mobile phone charger battery capacity tester
Product introduction:
Measuring range: DC 3V-9V, current: 0-3A (error: ± 1%), maximum support: 5A
5A current (the error will be 3% larger after exceeding 3A) Weight: 25g Package: anti-static bag
In 2018, the new USB voltmeter and ammeter can easily measure the output voltage of the USB port and the working current of the device! (Please note that it can only truthfully display the real-time working voltage and current of the appliance, and it does not have the function of a discharge meter, that is, it cannot set the voltage and current to discharge! It is compact and does not require a power supply and other auxiliary equipment, plug and play! It can also detect the charging current and voltage of any USB charger (computer USB, home charger, car charger), This is used to judge whether the performance of the charger and the performance of the charging line meet the requirements! Wide range of applications, any mobile phone, any electronic product, can be used, easy to operate, suitable for factories, exhibition demonstrations, laboratories and users!
Product features:
1. This product can measure the voltage of the USB power supply device when it is empty or loaded, and the voltage and current of the USB terminal device when it is working.
2. The display of current and voltage cycle is simple, convenient and practical.
3. Compact and easy to carry, no need to connect another power supply
