USB Tester Provides a reading of the charging voltage and current from USB ports, whether it's a wall charger port for a mobile, a car charging port, a portable power bank charging port, or a computer... >> This reading helps you identify charging problems caused by ports, cables, or chargers, and even identify cables and chargers that support fast charging... You can test and sort out bad cables and charging ports at home or in the car, and maintain your mobile's normal charging when you notice slow charging, the charger is no longer charging, no longer supports fast charging, or the mobile heats up during charging. Reading screen codes and their meanings: ◾V / Voltage output from the source ◾A / Amperage the device draws from the charger ◾T / Time since the device was connected to the charger ◾mAh / Milliampere-hours the energy consumed by the device 📗 The following readings are normal and ideal: ◾ Charging from a computer port Normal 5.0 to 4.8 Volts - Amperage 0.5 to 0.4 Slow charging ◾ Normal 5V/1A wall charger: Normal 5.1 to 4.9 Volts - Amperage 1.0 to 0.8 Slow to medium charging ◾ Fast 5V2A wall charger: Normal 5.0 to 5.1 Volts - Amperage 2.4 to 1.5 Fast charging 📙 Notice if the voltage reading is Less than 4.5 Volts, the cable is bad or too long ❌ Current less than 0.5 Amps despite the charger being good, meaning the cable or USB port is weak ❌ The device does not charge at all, the cable is broken or the charger is damaged ❌ Device Information / 🔸 Type / USB Tester 🔸 Display Type / Digital 🔸 Model / KWS-V20 🔸 Brand / Bolantedz 🔸 Voltage from 4 Volts to 20 Volts 🔸 Current from 0 to 3A 🔸 Time from zero to 99 hours ◾ Condition / New ◾ Price / 15 Riyals 📌 Location / Tabuk 📞 Contact / Haraj messages or mobile contact
